A field trail includes permeable reactive barrier (PRB) took place at a severely contaminated site in Yorkshire to the north of the UK through the SMiRT (Soil Mix Remediation Technology) project in May 2011. SMiRT involved the execution of the largest research field trials in the UK to provide field validation. Innovative modified bentonite materials in combination with zeolite and organoclay were used to construct six different walls of a hexagonal PRB. Field monitoring, testing and site cores were collected from the PRB twice: once 2 months after the construction and again in March 2014 (almost 34 months later).This paper presents an overview of the results of the PRB materials’ relative performance with some initial 3-year time-related assessment. Results from the monitoring program and the site cores are presented. Some good correlations are seen together with some clear difference among the materials’ efficiency. These preliminary observations represent a potential for further investigations and highlighted the main lessons learned in a filed scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=in-situ%20remediation" title="in-situ remediation">in-situ remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=permeable%20reactive%20barrier" title=" permeable reactive barrier"> permeable reactive barrier</a>, <a href="https://publications.waset.org/abstracts/search?q=site%20cores" title=" site cores"> site cores</a> </p> <a href="https://publications.waset.org/abstracts/56733/soil-mixed-constructed-permeable-reactive-barrier-for-groundwater-remediation-field-observation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56733.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2648</span> Sustainability Assessment Tool for the Selection of Optimal Site Remediation Technologies for Contaminated Gasoline Sites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Connor%20Dunlop">Connor Dunlop</a>, <a href="https://publications.waset.org/abstracts/search?q=Bassim%20Abbassi"> Bassim Abbassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20G.%20Zytner"> Richard G.

Many studies utilize the LCA methodology within the site remediation field to compare various decontamination methods, including bioremediation, soil vapor extraction or excavation, and off-site disposal. However, with the authors' best knowledge, limited information is available in the literature on a sustainability tool that could be used to help with the selection of the optimal remediation technology. This tool, based on the LCA methodology, would consider site conditions like environmental, economic, and social impacts. Accordingly, this project was undertaken to develop a tool to assist with the selection of optimal sustainable technology. Developing a proper tool requires a large amount of data. As such, data was collected from previous LCA studies looking at site remediation technologies. This step identified knowledge gaps or limitations within project data. Next, utilizing the data obtained from the literature review and other organizations, an extensive LCA study is being completed following the ISO 14040 requirements. Initial technologies being compared include bioremediation, excavation with off-site disposal, and a no-remediation option for a generic gasoline-contaminated site. To complete the LCA study, the modelling software SimaPro is being utilized. A sensitivity analysis of the LCA results will also be incorporated to evaluate the impact on the overall results. Finally, the economic and social impacts associated with each option will then be reviewed to understand how they fluctuate at different sites. All the results will then be summarized, and an interactive tool using Excel will be developed to help select the best sustainable site remediation technology. Preliminary LCA results show improved sustainability for the decontamination of a gasoline-contaminated site for each technology compared to the no-remediation option. Sensitivity analyses are now being completed on on-site parameters to determine how the environmental impacts fluctuate at other contaminated gasoline locations as the parameters vary, including soil type and transportation distances. Additionally, the social improvements and overall economic costs associated with each technology are being reviewed. Utilizing these results, the sustainability tool created to assist in the selection of the overall best option will be refined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title="life cycle assessment">life cycle assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=site%20remediation" title=" site remediation"> site remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability%20tool" title=" sustainability tool"> sustainability tool</a>, <a href="https://publications.waset.org/abstracts/search?q=contaminated%20sites" title=" contaminated sites"> contaminated sites</a> </p> <a href="https://publications.waset.org/abstracts/181499/sustainability-assessment-tool-for-the-selection-of-optimal-site-remediation-technologies-for-contaminated-gasoline-sites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181499.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">58</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2647</span> Soil Remediation Technologies towards Green Remediation Strategies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Petruzzelli">G.

Many contaminated sites have been discovered in industrialized countries and their remediation is a priority in environmental legislations. The aim of this paper is to provide the evolution of remediation from consolidated invasive technologies to environmental friendly green strategies. Many clean-up technologies have been used. Nowadays the technologies selection is no longer exclusively based on eliminating the source of pollution, but the aim of remediation includes also the recovery of soil quality. “Green remediation”, a strategy based on “soft technologies”, appears the key to tackle the issue of remediation of contaminated sites with the greatest attention to environmental quality, including the preservation of soil functionality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioremediation" title="bioremediation">bioremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=Green%20Remediation" title=" Green Remediation"> Green Remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoremediation" title=" phytoremediation"> phytoremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=remediation%20technologies" title=" remediation technologies"> remediation technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a> </p> <a href="https://publications.waset.org/abstracts/44439/soil-remediation-technologies-towards-green-remediation-strategies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44439.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">230</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2646</span> A Case Study: Remediation of Abandoned Mines for Residential Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Issa%20S.%20Oweis">Issa S.

The mine stope is about 137 m (450 long) and dipping over 344m (800 feet) at 450 to 500. As the building footprint straddles, the mine site needed remediation. The remediation scheme consisted of compaction grouting a minimum 10 m (30 ft.) depth of the mine stope in rock to establish a buttress for the hanging wall and allow support of the building foundation. The rock strength parameters (friction and cohesion) were established based on Hoek Geologic Strength Index (GSI). The derived strength parameters were used in the wedge analysis to simulate rock cave-in. It was concluded that a cave-in would be unlikely. Verification holes confirmed the effectiveness of grouting. Although post grouting micro gravity survey depicted a few anomalies, no anomalies were found to exist by further drilling and excavation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grout" title="grout">grout</a>, <a href="https://publications.waset.org/abstracts/search?q=stope" title=" stope"> stope</a>, <a href="https://publications.waset.org/abstracts/search?q=rock" title=" rock"> rock</a>, <a href="https://publications.waset.org/abstracts/search?q=properties" title=" properties"> properties</a> </p> <a href="https://publications.waset.org/abstracts/57720/a-case-study-remediation-of-abandoned-mines-for-residential-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57720.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">330</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2645</span> Remediation Activities in Bagnoli Superfund Site: An Italian Case of Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Bellagamba">S.

To reduce asbestos-related health effects, Italy has adopted many laws and regulations regarding exposure thresholds, limits, and remediation tools. The Italian Environmental Ministry (MASE) has identified 42 Italian Superfund sites, 11 of which are mainly contaminated by Asbestos. The highest levels of exposure occur during remediation activities in the 42 superfund-sites and during the management of asbestos containing waste in landfills, which requires specific procedures. INAIL-DIT play a role as MASE scientific consultant on issues concerning pollution, remediation, and Asbestos Containing Waste (ACW) management. The aim is to identify the best Emergency Safety Measures, to suggest specific best pratics for remediation through occupational on site monitorings and laboratory analysis. Moreover, the aim of INAIL research is testing the available technologies for working activities and analytical methodologies. This paper describes the remediation of Bagnoli industrial facility (Naples), an Eternit factory which produced asbestos cement products. The remediation has been analyzed, considering a first phase focused on the demolition of structures and plants and a second phase regarding the characterization, screening, removal, and disposal of polluted soils. The project planned the complete removal of all the asbestos dispersed in the soil and subsoil and the recovery of the clean fraction. This work highlights the remediation techniques used and the prevention measures provide for workers and daily life areas protection. This study, considering the high number of asbestos cement factories in the world, can to serve as an important reference for similar situation at European or international scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=safety" title="safety">safety</a>, <a href="https://publications.waset.org/abstracts/search?q=asbestos" title=" asbestos"> asbestos</a>, <a href="https://publications.waset.org/abstracts/search?q=workers" title=" workers"> workers</a>, <a href="https://publications.waset.org/abstracts/search?q=contaminated%20sites" title=" contaminated sites"> contaminated sites</a>, <a href="https://publications.waset.org/abstracts/search?q=hazardous%20waste" title=" hazardous waste"> hazardous waste</a> </p> <a href="https://publications.waset.org/abstracts/163725/remediation-activities-in-bagnoli-superfund-site-an-italian-case-of-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163725.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2644</span> Evaluation of Spatial Distribution Prediction for Site-Scale Soil Contaminants Based on Partition Interpolation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pengwei%20Qiao">Pengwei Qiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Sucai%20Yang"> Sucai Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenxia%20Wei"> Wenxia Wei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil pollution has become an important issue in China. Accurate spatial distribution prediction of pollutants with interpolation methods is the basis for soil remediation in the site. However, a relatively strong variability of pollutants would decrease the prediction accuracy. Theoretically, partition interpolation can result in accurate prediction results. In order to verify the applicability of partition interpolation for a site, benzo (b) fluoranthene (BbF) in four soil layers was adopted as the research object in this paper. IDW (inverse distance weighting)-, RBF (radial basis function)-and OK (ordinary kriging)-based partition interpolation accuracies were evaluated, and their influential factors were analyzed; then, the uncertainty and applicability of partition interpolation were determined. Three conclusions were drawn. (1) The prediction error of partitioned interpolation decreased by 70% compared to unpartitioned interpolation. (2) Partition interpolation reduced the impact of high CV (coefficient of variation) and high concentration value on the prediction accuracy. (3) The prediction accuracy of IDW-based partition interpolation was higher than that of RBF- and OK-based partition interpolation, and it was suitable for the identification of highly polluted areas at a contaminated site. These results provide a useful method to obtain relatively accurate spatial distribution information of pollutants and to identify highly polluted areas, which is important for soil pollution remediation in the site. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accuracy" title="accuracy">accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=applicability" title=" applicability"> applicability</a>, <a href="https://publications.waset.org/abstracts/search?q=partition%20interpolation" title=" partition interpolation"> partition interpolation</a>, <a href="https://publications.waset.org/abstracts/search?q=site" title=" site"> site</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20pollution" title=" soil pollution"> soil pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a> </p> <a href="https://publications.waset.org/abstracts/110125/evaluation-of-spatial-distribution-prediction-for-site-scale-soil-contaminants-based-on-partition-interpolation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110125.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2643</span> 3-Dimensional Contamination Conceptual Site Model: A Case Study Illustrating the Multiple Applications of Developing and Maintaining a 3D Contamination Model during an Active Remediation Project on a Former Urban Gasworks Site</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duncan%20Fraser">Duncan Fraser</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A 3-Dimensional (3D) conceptual site model was developed using the Leapfrog Works® platform utilising a comprehensive historical dataset for a large former Gasworks site in Fitzroy, Melbourne. The gasworks had been constructed across two fractured geological units with varying hydraulic conductivities. A Newer Volcanic (basaltic) outcrop covered approximately half of the site and was overlying a fractured Melbourne formation (Siltstone) bedrock outcropping over the remaining portion. During the investigative phase of works, a dense non-aqueous phase liquid (DNAPL) plume (coal tar) was identified within both geological units in the subsurface originating from multiple sources, including gasholders, tar wells, condensers, and leaking pipework. The first stage of model development was undertaken to determine the horizontal and vertical extents of the coal tar in the subsurface and assess the potential causality between potential sources, plume location, and site geology. Concentrations of key contaminants of interest (COIs) were also interpolated within Leapfrog to refine the distribution of contaminated soils. The model was subsequently used to develop a robust soil remediation strategy and achieve endorsement from an Environmental Auditor. A change in project scope, following the removal and validation of the three former gasholders, necessitated the additional excavation of a significant volume of residual contaminated rock to allow for the future construction of two-story underground basements. To assess financial liabilities associated with the offsite disposal or thermal treatment of material, the 3D model was updated with three years of additional analytical data from the active remediation phase of works. Chemical concentrations and the residual tar plume within the rock fractures were modelled to pre-classify the in-situ material and enhance separation strategies to prevent the unnecessary treatment of material and reduce costs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20model" title="3D model">3D model</a>, <a href="https://publications.waset.org/abstracts/search?q=contaminated%20land" title=" contaminated land"> contaminated land</a>, <a href="https://publications.waset.org/abstracts/search?q=Leapfrog" title=" Leapfrog"> Leapfrog</a>, <a href="https://publications.waset.org/abstracts/search?q=remediation" title=" remediation"> remediation</a> </p> <a href="https://publications.waset.org/abstracts/150672/3-dimensional-contamination-conceptual-site-model-a-case-study-illustrating-the-multiple-applications-of-developing-and-maintaining-a-3d-contamination-model-during-an-active-remediation-project-on-a-former-urban-gasworks-site" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150672.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2642</span> Assessing Sydney Tar Ponds Remediation and Natural Sediment Recovery in Nova Scotia, Canada</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tony%20R.%20Walker">Tony R.

Contaminated effluents from the industrial site resulted in the creation of the Sydney Tar Ponds, one of Canada’s largest contaminated sites. Since its closure, there have been several attempts to remediate this former industrial site and finally, in 2004, the governments of Canada and Nova Scotia committed to remediate the site to reduce potential ecological and human health risks to the environment. The Sydney Tar Ponds and Coke Ovens cleanup project has become the most prominent remediation project in Canada today. As an integral part of remediation of the site (i.e., which consisted of solidification/stabilization and associated capping of the Tar Ponds), an extensive multiple media environmental effects program was implemented to assess what effects remediation had on the surrounding environment, and, in particular, harbour sediments. Additionally, longer-term natural sediment recovery rates of select contaminants predicted for the harbour sediments were compared to current conditions. During remediation, potential contributions to sediment quality, in addition to remedial efforts, were evaluated which included a significant harbour dredging project, propeller wash from harbour traffic, storm events, adjacent loading/unloading of coal and municipal wastewater treatment discharges. Two sediment sampling methodologies, sediment grab and gravity corer, were also compared to evaluate the detection of subtle changes in sediment quality. Results indicated that overall spatial distribution pattern of historical contaminants remains unchanged, although at much lower concentrations than previously reported, due to natural recovery. Measurements of sediment indicator parameter concentrations confirmed that natural recovery rates of Sydney Harbour sediments were in broad agreement with predicted concentrations, in spite of ongoing remediation activities. Overall, most measured parameters in sediments showed little temporal variability even when using different sampling methodologies, during three years of remediation compared to baseline, except for the detection of significant increases in total PAH concentrations noted during one year of remediation monitoring. The data confirmed the effectiveness of mitigation measures implemented during construction relative to harbour sediment quality, despite other anthropogenic activities and the dynamic nature of the harbour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contaminated%20sediment" title="contaminated sediment">contaminated sediment</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery" title=" recovery"> recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=remediation" title=" remediation"> remediation</a> </p> <a href="https://publications.waset.org/abstracts/42968/assessing-sydney-tar-ponds-remediation-and-natural-sediment-recovery-in-nova-scotia-canada" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42968.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">236</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2641</span> Sustained-Release Persulfate Tablets for Groundwater Remediation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Chen%20Chang">Yu-Chen Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yen-Ping%20Peng"> Yen-Ping Peng</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei-Yu%20Chen"> Wei-Yu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ku-Fan%20Chen"> Ku-Fan Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Contamination of soil and groundwater has become a serious and widespread environmental problem. In this study, sustained-release persulfate tablets were developed using persulfate powder and a modified cellulose binder for organic-contaminated groundwater remediation. Conventional cement-based persulfate-releasing materials were also synthesized for the comparison. The main objectives of this study were to: (1) evaluate the release rates of the remedial tablets; (2) obtain the optimal formulas of the tablets; and (3) evaluate the effects of the tablets on the subsurface environment. The results of batch experiments show that the optimal parameter for the preparation of the persulfate-releasing tablet was persulfate:cellulose = 1:1 (wt:wt) with a 5,000 kg F/cm2 of pressure application. The cellulose-based persulfate tablet was able to release 2,030 mg/L of persulfate per day for 10 days. Compared to cement-based persulfate-releasing materials, the persulfate release rates of the cellulose-based persulfate tablets were much more stable. Moreover, since the tablets are soluble in water, no waste will be produced in the subsurface. The results of column tests show that groundwater flow would shorten the release time of the tablets. This study successfully developed unique persulfate tablets based on green remediation perspective. The efficacy of the persulfate-releasing tablets on the removal of organic pollutants needs to be further evaluated. The persulfate tablets are expected to be applied for site remediation in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustained-release%20persulfate%20tablet" title="sustained-release persulfate tablet">sustained-release persulfate tablet</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20cellulose" title=" modified cellulose"> modified cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20remediation" title=" green remediation"> green remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a> </p> <a href="https://publications.waset.org/abstracts/80243/sustained-release-persulfate-tablets-for-groundwater-remediation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80243.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2640</span> Remediation and Health: A Systematic Review of the Role of Resulting Displacement in Damaging Health and Wellbeing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rupert%20G.%20S.%20Legg">Rupert G. S. Legg</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The connection between poor health outcomes and living near contaminated land has long been understood. Less examined has been the impact of remediation on residents’ health. The cleaning process undoubtedly changes the local area in which it occurs, leading to the possibility that local housing and rental prices could increase resulting in the displacement of those least able to cope. Whether or not this potential displacement resulting from remediation has a considerable impact on health remains unknown. This review aims to determine how these health effects have been approached in the health geography literature. A systematic review of health geographies literature was conducted, searching for two-word clusters: ‘health’ and ‘remediation’ (100 articles); and ‘health’, ‘displacement’ and ‘gentrification’ (43 articles). 43 articles were selected for their relevance (7 from the first cluster, 20 from the second, and 16 from those cited within the reviewed articles). Several of the reviewed cases identified that potential displacement was a contributor to stress and worry in residents living near remediation projects. Likewise, the experience of displacement in other cases beyond remediation was linked with several mental health issues. However, no remediation cases followed-up on the ultimate effects of experiencing displacement on residents’ health. A reason identified for this was a tendency for reviewed studies to adopt a contextual or compositional approach, as opposed to a relational approach, which is more concerned with dimensions of mobility and temporality. Given that remediation and displacement both involve changing mobility and temporality, focussing solely on contextual or compositional factors is problematic. This review concludes by suggesting that more thorough, relational research is conducted into the extent to which potential displacement resulting from remediation affects health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contamination" title="contamination">contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=displacement" title=" displacement"> displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20geography" title=" health geography"> health geography</a>, <a href="https://publications.waset.org/abstracts/search?q=remediation" title=" remediation"> remediation</a> </p> <a href="https://publications.waset.org/abstracts/99490/remediation-and-health-a-systematic-review-of-the-role-of-resulting-displacement-in-damaging-health-and-wellbeing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99490.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">162</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2639</span> Mass Flux and Forensic Assessment: Informed Remediation Decision Making at One of Canada’s Most Polluted Sites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tony%20R.%20Walker">Tony R.

Contaminants comprised of coal tar residues which were discharged from coking ovens into a small tidal tributary, which became known as the Sydney Tar Ponds (STPs), and subsequently discharged into Sydney Harbour. An Environmental Impact Statement concluded that mobilization of contaminated sediments posed unacceptable ecological risks, therefore immobilizing contaminants in the STPs using solidification and stabilization was identified as a primary source control remediation option to mitigate against continued transport of contaminated sediments from the STPs into Sydney Harbour. Recent developments in contaminant mass flux techniques focus on understanding “mobile” vs. “immobile” contaminants at remediation sites. Forensic source evaluations are also increasingly used for understanding origins of PAH contaminants in soils or sediments. Flux and forensic source evaluation-informed remediation decision-making uses this information to develop remediation end point goals aimed at reducing off-site exposure and managing potential ecological risk. This study included reviews of previous flux studies, calculating current mass flux estimates and a forensic assessment using PAH fingerprint techniques, during remediation of one of Canada’s most polluted sites at the STPs. Historically, the STPs was thought to be the major source of PAH contamination in Sydney Harbour with estimated discharges of nearly 800 kg/year of PAHs. However, during three years of remediation monitoring only 17-97 kg/year of PAHs were discharged from the STPs, which was also corroborated by an independent PAH flux study during the first year of remediation which estimated 119 kg/year. The estimated mass efflux of PAHs from the STPs during remediation was in stark contrast to ~2000 kg loading thought necessary to cause a short term increase in harbour sediment PAH concentrations. These mass flux estimates during remediation were also between three to eight times lower than PAHs discharged from the STPs a decade prior to remediation, when at the same time, government studies demonstrated on-going reduction in PAH concentrations in harbour sediments. Flux results were also corroborated using forensic source evaluations using PAH fingerprint techniques which found a common source of PAHs for urban soils, marine and aquatic sediments in and around Sydney. Coal combustion (from historical coking) and coal dust transshipment (from current coal transshipment facilities), are likely the principal source of PAHs in these media and not migration of PAH laden sediments from the STPs during a large scale remediation project. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contaminated%20sediment" title="contaminated sediment">contaminated sediment</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20flux" title=" mass flux"> mass flux</a>, <a href="https://publications.waset.org/abstracts/search?q=forensic%20source%20evaluations" title=" forensic source evaluations"> forensic source evaluations</a>, <a href="https://publications.waset.org/abstracts/search?q=remediation" title=" remediation"> remediation</a> </p> <a href="https://publications.waset.org/abstracts/42964/mass-flux-and-forensic-assessment-informed-remediation-decision-making-at-one-of-canadas-most-polluted-sites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42964.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">239</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2638</span> GIS Technology for Environmentally Polluted Sites with Innovative Process to Improve the Quality and Assesses the Environmental Impact Assessment (EIA)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamad%20Almebayedh">Hamad Almebayedh</a>, <a href="https://publications.waset.org/abstracts/search?q=Chuxia%20Lin"> Chuxia Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20wang"> Yu wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The environmental impact assessment (EIA) must be improved, assessed, and quality checked for human and environmental health and safety. Soil contamination is expanding, and sites and soil remediation activities proceeding around the word which simplifies the answer “quality soil characterization” will lead to “quality EIA” to illuminate the contamination level and extent and reveal the unknown for the way forward to remediate, countifying, containing, minimizing and eliminating the environmental damage. Spatial interpolation methods play a significant role in decision making, planning remediation strategies, environmental management, and risk assessment, as it provides essential elements towards site characterization, which need to be informed into the EIA. The Innovative 3D soil mapping and soil characterization technology presented in this research paper reveal the unknown information and the extent of the contaminated soil in specific and enhance soil characterization information in general which will be reflected in improving the information provided in developing the EIA related to specific sites. The foremost aims of this research paper are to present novel 3D mapping technology to quality and cost-effectively characterize and estimate the distribution of key soil characteristics in contaminated sites and develop Innovative process/procedure “assessment measures” for EIA quality and assessment. The contaminated site and field investigation was conducted by innovative 3D mapping technology to characterize the composition of petroleum hydrocarbons contaminated soils in a decommissioned oilfield waste pit in Kuwait. The results show the depth and extent of the contamination, which has been interred into a developed assessment process and procedure for the EIA quality review checklist to enhance the EIA and drive remediation and risk assessment strategies. We have concluded that to minimize the possible adverse environmental impacts on the investigated site in Kuwait, the soil-capping approach may be sufficient and may represent a cost-effective management option as the environmental risk from the contaminated soils is considered to be relatively low. This research paper adopts a multi-method approach involving reviewing the existing literature related to the research area, case studies, and computer simulation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20EIA" title="quality EIA">quality EIA</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20interpolation" title=" spatial interpolation"> spatial interpolation</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20characterization" title=" soil characterization"> soil characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=contaminated%20site" title=" contaminated site"> contaminated site</a> </p> <a href="https://publications.waset.org/abstracts/162880/gis-technology-for-environmentally-polluted-sites-with-innovative-process-to-improve-the-quality-and-assesses-the-environmental-impact-assessment-eia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162880.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">88</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2637</span> Permeable Bio-Reactive Barriers to Tackle Petroleum Hydrocarbon Contamination in the Sub-Antarctic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benjamin%20L.%20Freidman">Benjamin L.

Migrating petroleum hydrocarbon spills can have a significant impact on terrestrial and marine ecosystems in cold regions, as harsh environmental conditions result in heightened sensitivity to pollution. This migration of contaminants has led to the development of Permeable Reactive Barriers (PRB) for application in cold regions. PRB’s are one of the most practical technologies for on-site or in-situ groundwater remediation in cold regions due to their minimal energy, monitoring and maintenance requirements. The Main Power House site has been used as a fuel storage and power generation area for the Macquarie Island research station since at least 1960. Soil analysis at the site has revealed Total Petroleum Hydrocarbon (TPH) (C9-C28) concentrations as high as 19,000 mg/kg soil. Groundwater TPH concentrations at this site can exceed 350 mg/L TPH. Ongoing migration of petroleum hydrocarbons into the neighbouring marine ecosystem resulted in the installation of a ‘funnel and gate’ PRB in November 2014. The ‘funnel and gate’ design successfully intercepted contaminated groundwater and analysis of TPH retention and biodegradation on PRB media are currently underway. Installation of the PRB facilitates research aimed at better understanding the contribution of particle attached biofilms to the remediation of groundwater systems. Bench-scale PRB system analysis at The University of Melbourne is currently examining the role biofilms play in petroleum hydrocarbon degradation, and how controlled release nutrient media can heighten the metabolic activity of biofilms in cold regions in the presence of low temperatures and low nutrient groundwater. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=groundwater" title="groundwater">groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=petroleum" title=" petroleum"> petroleum</a>, <a href="https://publications.waset.org/abstracts/search?q=Macquarie%20island" title=" Macquarie island"> Macquarie island</a>, <a href="https://publications.waset.org/abstracts/search?q=funnel%20and%20gate" title=" funnel and gate"> funnel and gate</a> </p> <a href="https://publications.waset.org/abstracts/37838/permeable-bio-reactive-barriers-to-tackle-petroleum-hydrocarbon-contamination-in-the-sub-antarctic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37838.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">358</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2636</span> Electrokinetic Remediation of Uranium Contaminated Soil by Ion Exchange Membranes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Z.%20H.%20Shi">Z.

The electrokinetic process is one of the most promising remediation techniques for sludge, sediment, and saturated or unsaturated soils contaminated with heavy metals and radionuclides. However, secondary waste is a major concern for soil contaminated with nuclides. To minimize the generation of secondary wastes, this study used the anion and cation exchange membranes to improve the performance of the experimental apparatus. Remediation experiments of uranium-contaminated soil were performed with different agents. The results show that using acetic acid and EDTA as chelating agents clearly enhances the migration ability of the uranium. The ion exchange membranes (IEMs) used in the experiments not only reduce secondary wastes, but also, keep the soil pH stable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrokinetic%20remediation" title="electrokinetic remediation">electrokinetic remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20exchange%20membranes" title=" ion exchange membranes"> ion exchange membranes</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=uranium" title=" uranium"> uranium</a> </p> <a href="https://publications.waset.org/abstracts/48962/electrokinetic-remediation-of-uranium-contaminated-soil-by-ion-exchange-membranes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48962.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">352</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2635</span> Remediation of Heavy Metal Contaminated Soil with Vivianite Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shinen%20B.">Shinen B.</a>, <a href="https://publications.waset.org/abstracts/search?q=Bavor%20J."> Bavor J.</a>, <a href="https://publications.waset.org/abstracts/search?q=Dorjkhand%20B."> Dorjkhand B.</a>, <a href="https://publications.waset.org/abstracts/search?q=Suvd%20B."> Suvd B.</a>, <a href="https://publications.waset.org/abstracts/search?q=Maitsetseg%20B."> Maitsetseg B.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A number of remediation techniques are available for the treatment of soils and sediments contaminated by heavy metals.

This study was carried out to scrutinize the feasibility of vivianite nanoparticles for remediation of soils contaminated with heavy metals. Column experiments were performed in the laboratory to examine nanoparticle sequestration of metal in soil amended with vivianite nanoparticle suspension. The effect of environmental parameters such as temperature, pH and redox potential on metal leachability and bioavailability of soil amended with nanoparticle suspension was examined and compared with non-amended soils. The vivianite was effective in reducing the leachability of metals in soils. It is suggested that vivianite nanoparticles could be applied for the remediation of contaminated sites polluted by heavy metals due to mining activities, particularly in Mongolia, where mining industries have been developing rapidly in the last decade. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioavailability" title="bioavailability">bioavailability</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=remediation" title=" remediation"> remediation</a> </p> <a href="https://publications.waset.org/abstracts/121769/remediation-of-heavy-metal-contaminated-soil-with-vivianite-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121769.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">190</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2634</span> Data Management System for Environmental Remediation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elizaveta%20Petelina">Elizaveta Petelina</a>, <a href="https://publications.waset.org/abstracts/search?q=Anton%20Sizo"> Anton Sizo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Environmental remediation projects deal with a wide spectrum of data, including data collected during site assessment, execution of remediation activities, and environmental monitoring. Therefore, an appropriate data management is required as a key factor for well-grounded decision making. The Environmental Data Management System (EDMS) was developed to address all necessary data management aspects, including efficient data handling and data interoperability, access to historical and current data, spatial and temporal analysis, 2D and 3D data visualization, mapping, and data sharing. The system focuses on support of well-grounded decision making in relation to required mitigation measures and assessment of remediation success. The EDMS is a combination of enterprise and desktop level data management and Geographic Information System (GIS) tools assembled to assist to environmental remediation, project planning, and evaluation, and environmental monitoring of mine sites. EDMS consists of seven main components: a Geodatabase that contains spatial database to store and query spatially distributed data; a GIS and Web GIS component that combines desktop and server-based GIS solutions; a Field Data Collection component that contains tools for field work; a Quality Assurance (QA)/Quality Control (QC) component that combines operational procedures for QA and measures for QC; Data Import and Export component that includes tools and templates to support project data flow; a Lab Data component that provides connection between EDMS and laboratory information management systems; and a Reporting component that includes server-based services for real-time report generation. The EDMS has been successfully implemented for the Project CLEANS (Clean-up of Abandoned Northern Mines). Project CLEANS is a multi-year, multimillion-dollar project aimed at assessing and reclaiming 37 uranium mine sites in northern Saskatchewan, Canada. The EDMS has effectively facilitated integrated decision-making for CLEANS project managers and transparency amongst stakeholders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20management" title="data management">data management</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20remediation" title=" environmental remediation"> environmental remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=geographic%20information%20system" title=" geographic information system"> geographic information system</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title=" decision making"> decision making</a> </p> <a href="https://publications.waset.org/abstracts/115840/data-management-system-for-environmental-remediation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115840.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2633</span> Efficient of Technology Remediation Soil That Contaminated by Petroleum Based on Heat without Combustion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gavin%20Hutama%20Farandiarta">Gavin Hutama Farandiarta</a>, <a href="https://publications.waset.org/abstracts/search?q=Hegi%20Adi%20Prabowo"> Hegi Adi Prabowo</a>, <a href="https://publications.waset.org/abstracts/search?q=Istiara%20Rizqillah%20Hanifah"> Istiara Rizqillah Hanifah</a>, <a href="https://publications.waset.org/abstracts/search?q=Millati%20Hanifah%20Saprudin"> Millati Hanifah Saprudin</a>, <a href="https://publications.waset.org/abstracts/search?q=Raden%20Iqrafia%20Ashna"> Raden Iqrafia Ashna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increase of the petroleum’s consumption rate encourages industries to optimize and increase the activity in processing crude oil into petroleum. However, although the result gives a lot of benefits to humans worldwide, it also gives negative impact to the environment. One of the negative impacts of processing crude oil is the soil will be contaminated by petroleum sewage sludge. This petroleum sewage sludge, contains hydrocarbon compound and it can be calculated by Total Petroleum Hydrocarbon (TPH).Petroleum sludge waste is accounted as hazardous and toxic. The soil contamination caused by the petroleum sludge is very hard to get rid of. However, there is a way to manage the soil that is contaminated by petroleum sludge, which is by using heat (thermal desorption) in the process of remediation. There are several factors that affect the success rate of the remediation with the help of heat which are temperature, time, and air pressure in the desorption column. The remediation process using the help of heat is an alternative in soil recovery from the petroleum pollution which highly effective, cheap, and environmentally friendly that produces uncontaminated soil and the petroleum that can be used again. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=petroleum%20sewage%20sludge" title="petroleum sewage sludge">petroleum sewage sludge</a>, <a href="https://publications.waset.org/abstracts/search?q=remediation%20soil" title=" remediation soil"> remediation soil</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20desorption" title=" thermal desorption"> thermal desorption</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20petroleum%20hydrocarbon%20%28TPH%29" title=" total petroleum hydrocarbon (TPH)"> total petroleum hydrocarbon (TPH)</a> </p> <a href="https://publications.waset.org/abstracts/48698/efficient-of-technology-remediation-soil-that-contaminated-by-petroleum-based-on-heat-without-combustion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48698.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">247</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2632</span> Systematic Review of Misconceptions: Tools for Diagnostics and Remediation Models for Misconceptions in Physics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Iqbal">Muhammad Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Edi%20Istiyono"> Edi Istiyono</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Misconceptions are one of the problems in physics learning where students' understanding is not in line with scientific theory. The aim of this research is to find diagnostic tools to identify misconceptions and how to remediate physics misconceptions. In this research, the articles that will be reviewed come from the Scopus database related to physics misconceptions from 2013-2023. The articles obtained from the Scopus database were then selected according to the Prisma model, so 29 articles were obtained that focused on discussing physics misconceptions, especially regarding diagnostic tools and remediation methods. Currently, the most widely used diagnostic tool is the four-tier test, which is able to measure students' misconceptions in depth by knowing whether students are guessing or not and from then on, there is also a trend toward five-tier diagnostic tests with additional sources of information obtained. So that the origin of students' misconceptions is known. There are several ways to remediate student misconceptions, namely 11 ways and one of the methods used is digital practicum so that abstract things can be visualized into real ones. This research is limited to knowing what tools are used to diagnose and remediate misconceptions, so it is not yet known how big the effect of remediation methods is on misconceptions. The researcher recommends that in the future further research can be carried out to find out the most appropriate remediation method for remediating student misconceptions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=misconception" title="misconception">misconception</a>, <a href="https://publications.waset.org/abstracts/search?q=remediation" title=" remediation"> remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=systematic%20review" title=" systematic review"> systematic review</a>, <a href="https://publications.waset.org/abstracts/search?q=tools" title=" tools"> tools</a> </p> <a href="https://publications.waset.org/abstracts/185854/systematic-review-of-misconceptions-tools-for-diagnostics-and-remediation-models-for-misconceptions-in-physics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185854.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">36</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2631</span> Phytoextraction of Heavy Metals in a Contaminated Site in Assam, India Using Indian Pennywort and Fenugreek: An Experimental Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chinumani%20Choudhury">Chinumani Choudhury</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy metal contamination is an alarming problem, which poses a serious risk to human health and the surrounding geology. Soils get contaminated with heavy metals due to the un-regularized industrial discharge of the toxic metal-rich effluents. Under such a condition, the remediation of the contaminated sites becomes imperative for a sustainable, safe, and healthy environment. Phytoextraction, which involves the removal of heavy metals from the soil through root absorption and uptake, is a viable remediation technique, which ensures extraction of the toxic inorganic compound available in the soil even at low concentrations. The soil present in the Silghat Region of Assam, India, is mostly contaminated with Zinc (Zn) and Lead (Pb), having concentrations as high as to cause a serious environmental problem if proper measures are not taken. In the present study, an extensive experimental study was carried out to understand the effectiveness of two commonly planted trees in Assam, namely, i) Indian Pennywort and ii) Fenugreek, in the removal of heavy metals from the contaminated soil. The basic characterization of the soil in the contaminated site of the Silghat region was performed and the field concentration of Zn and Pb was recorded. Various long-term laboratory pot tests were carried out by sowing the seeds of Indian Pennywort and Fenugreek in a soil, which was spiked, with a very high dosage of Zn and Pb. The tests were carried out for different concentration of a particular heavy metal and the individual effectiveness in the absorption of the heavy metal by the plants were studied. The concentration of the soil was monitored regularly to assess the rate of depletion and the simultaneous uptake of the heavy metal from the soil to the plant. The amount of heavy metal uptake by the plant was also quantified by analyzing the plant sample at the end of the testing period. Finally, the study throws light on the applicability of the studied plants in the field for effective remediation of the contaminated sites of Assam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phytoextraction" title="phytoextraction">phytoextraction</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy-metals" title=" heavy-metals"> heavy-metals</a>, <a href="https://publications.waset.org/abstracts/search?q=Indian%20pennywort" title=" Indian pennywort"> Indian pennywort</a>, <a href="https://publications.waset.org/abstracts/search?q=fenugreek" title=" fenugreek"> fenugreek</a> </p> <a href="https://publications.waset.org/abstracts/127760/phytoextraction-of-heavy-metals-in-a-contaminated-site-in-assam-india-using-indian-pennywort-and-fenugreek-an-experimental-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127760.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2630</span> Remediation of Oil and Gas Exploration and Production (O&G E&P) Wastes Using Soil-Poultry Dropping Amendment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ofonime%20U.%20M.%20John">Ofonime U.

Culture-dependent microbiological, chemical and enzymatic techniques were employed to assess the efficacy of remediation process. Microbiological activities of the remediated wastes showed increased hydrocarbonoclastic microbial populations with increased remediation time; 2.7±0.1 x 105cfu/g to 8.3 ± 0.04 x106cfu/g for hydrocarbon utilizing bacteria, 1.7 ± 0.2 x103cfu/g to 6.0 ± 0.01 x 104cfu/g for hydrocarbon utilizing fungi and 2.2 ± 0.1 x 102cfu/g to 6.7 ± 0.1 x 103cfu/g for hydrocarbon utilizing actinomycetes. Bacteria associated with the remediated wastes after the remediation period included the genera Bacillus, Psuedomonas, Beijerinckia, Acinetobacter, Alcaligenes and Serratia. Fungal isolates included species of Penicillium, Aspergillus and Cladosporium, while the Actinomycetes included species of Rhodococcus, Nocardia and Streptomyces. Slight fluctuations in pH values between 6.5± 0.2 and 7.1 ± 0.08 were recorded throughout the process, while total petroleum hydrocarbon (TPH) content decreased from 89, 900 ± 0.03mg/kg to 425 ± 0.1 mg/kg after twelve weeks of remediation. The polycyclic aromatic hydrocarbon (PAH) levels decreased with increased remediation time; naphthalene, flourene, pheneanthrene, anthracene, pyrene, chrysene and benzo(b)flouranthene showed decreased values < 0.01 after twelve weeks of remediation. Enzyme activities revealed increased dehydrogenase and urease activities with increased remediation time and decreased phenol oxidase activity with increased remediation period. There was a positive linear correlation between densities of hydrocarbonoclastic microbes and dehydrogenase activity. On the contrary, phenol oxidase and urease activities showed negative correlation with microbial population. Results of this study confirmed that remediation of oily wastes using soil-poultry dropping amendment can result in eco-friendly O&G E&P wastes. It also indicates that urease and phenol oxidase activities can be reliable indices/tools to monitor PAH levels and rates of petroleum hydrocarbon degradation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dehydrogenase%20activity" title="dehydrogenase activity">dehydrogenase activity</a>, <a href="https://publications.waset.org/abstracts/search?q=oily%20wastes" title=" oily wastes"> oily wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=remediation" title=" remediation"> remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=soil-poultry%20dropping%20amendment" title=" soil-poultry dropping amendment"> soil-poultry dropping amendment</a> </p> <a href="https://publications.waset.org/abstracts/24504/remediation-of-oil-and-gas-exploration-and-production-og-ep-wastes-using-soil-poultry-dropping-amendment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24504.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">322</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2629</span> Kuwait Environmental Remediation Program: Fresh Groudwater Risk Assessement from Tarcrete Material across the Raudhatain and Sabriyah Oil Fields, North Kuwait</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nada%20Al-Qallaf">Nada Al-Qallaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Aisha%20Al-Barood"> Aisha Al-Barood</a>, <a href="https://publications.waset.org/abstracts/search?q=Djamel%20Lekmine"> Djamel Lekmine</a>, <a href="https://publications.waset.org/abstracts/search?q=Srinivasan%20Vedhapuri"> Srinivasan Vedhapuri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Kuwait Oil Company (KOC) under the supervision of Kuwait National Focal Point (KNFP) is planning to remediate 26 million (M) m3 of oil-contaminated soil in oil fields of Kuwait as a direct and indirect fallout of the Gulf War during 1990-1991. This project is funded by the United Nations Compensation Commission (UNCC) under the Kuwait Environmental Remediation Program (KERP). Oil-contamination of the soil occurred due to the destruction of the oil wells and spilled crude oil across the land surface and created ‘oil lakes’ in low lying land. Aerial fall-out from oil spray and combustion products from oil fires combined with the sand and gravel on the ground surface to form a layer of hardened ‘Tarcrete’. The unique fresh groundwater lenses present in the Raudhatain and Sabriya subsurface areas had been impacted by the discharge and/or spills of dissolved petroleum constituents. These fresh groundwater aquifers were used for drinking water purposes until 1990, prior to invasion. This has significantly damages altered the landscape, ecology and habitat of the flora and fauna and in Kuwait Desert. Under KERP, KOC is fully responsible for the planning and execution of the remediation and restoration projects in KOC oil fields. After the initial recommendation of UNCC to construct engineered landfills for containment and disposal of heavily contaminated soils, two landfills were constructed, one in North Kuwait and another in South East Kuwait of capacity 1.7 million m3 and 0.5 million m3 respectively. KOC further developed the Total Remediation Strategy in conjunction with KNFP and has obtained UNCC approval. The TRS comprises of elements such as Risk Based Approach (RBA), Bioremediation of low Contaminated Soil levels, Remediation Treatment Technologies, Sludge Disposal via Beneficial Recycling or Re-use and Engineered landfills for Containment of untreatable materials. Risk Based Assessment as a key component to avoid any unnecessary remedial works, where it can be demonstrated that human health and the environment are sufficiently protected in the absence of active remediation. This study demonstrates on the risks of tarcrete materials spread over areas 20 Km2 on the fresh Ground water lenses/catchment located beneath the Sabriyah and Raudhatain oil fields in North Kuwait. KOC’s primary objective is to provide justification of using RBA, to support a case with the Kuwait regulators to leave the tarcrete material in place, rather than seek to undertake large-scale removal and remediation. The large-scale coverage of the tarcrete in the oil fields and perception that the residual contamination associated with this source is present in an environmentally sensitive area essentially in ground water resource. As part of this assessment, conceptual site model (CSM) and complete risk-based and fate and transport modelling was carried out which includes derivation of site-specific assessment criteria (SSAC) and quantification of risk to identified waters resource receptors posed by tarcrete impacted areas. The outcome of this assessment was determined that the residual tarcrete deposits across the site area shall not create risks to fresh groundwater resources and the remedial action to remove and remediate the surficial tarcrete deposits is not warranted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conceptual%20site%20model" title="conceptual site model">conceptual site model</a>, <a href="https://publications.waset.org/abstracts/search?q=fresh%20groundwater" title=" fresh groundwater"> fresh groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=oil-contaminated%20soil" title=" oil-contaminated soil"> oil-contaminated soil</a>, <a href="https://publications.waset.org/abstracts/search?q=tarcrete" title=" tarcrete"> tarcrete</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20based%20assessment" title=" risk based assessment"> risk based assessment</a> </p> <a href="https://publications.waset.org/abstracts/136951/kuwait-environmental-remediation-program-fresh-groudwater-risk-assessement-from-tarcrete-material-across-the-raudhatain-and-sabriyah-oil-fields-north-kuwait" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136951.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">174</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2628</span> The Composting Process from a Waste Management Method to a Remediation Procedure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Petruzzelli">G.

In recent years composting has been increasingly used as a remediation technology to remove biodegradable contaminants from soil, and to modulate heavy metals bioavailability in phytoremediation strategies. An optimization in the recovery of resources from wastes through composting could enhance soil fertility and promote its use in the remediation biotechnologies of contaminated soils. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture" title="agriculture">agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=biopile" title=" biopile"> biopile</a>, <a href="https://publications.waset.org/abstracts/search?q=compost" title=" compost"> compost</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20clean-up" title=" soil clean-up"> soil clean-up</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20recycling" title=" waste recycling"> waste recycling</a> </p> <a href="https://publications.waset.org/abstracts/6245/the-composting-process-from-a-waste-management-method-to-a-remediation-procedure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6245.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">309</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2627</span> Kuwait Environmental Remediation Program: Waste Management Data Analytics for Planning and Optimization of Waste Collection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aisha%20Al-Baroud">Aisha Al-Baroud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The United Nations Compensation Commission (UNCC), Kuwait National Focal Point (KNFP) and Kuwait Oil Company (KOC) cooperated in a joint project to undertake comprehensive and collaborative efforts to remediate 26 million m3 of crude oil contaminated soil that had resulted from the Gulf War in 1990/1991. These efforts are referred to as the Kuwait Environmental Remediation Program (KERP). KOC has developed a Total Remediation Solution (TRS) for KERP, which will guide the Remediation projects, comprises of alternative remedial solutions with treatment techniques inclusive of limited landfills for non-treatable soil materials disposal, and relies on treating certain ranges of Total Petroleum Hydrocarbon (TPH) contamination with the most appropriate remediation techniques. The KERP Remediation projects will be implemented within the KOC’s oilfields in North and South East Kuwait. The objectives of this remediation project is to clear land for field development and treat all the oil contaminated features (dry oil lakes, wet oil lakes, and oil contaminated piles) through TRS plan to optimize the treatment processes and minimize the volume of contaminated materials to be placed into landfills. The treatment strategy will comprise of Excavation and Transportation (E&T) of oil contaminated soils from contaminated land to remote treatment areas and to use appropriate remediation technologies or a combination of treatment technologies to achieve remediation target criteria (RTC). KOC has awarded five mega projects to achieve the same and is currently in the execution phase. As a part of the company’s commitment to environment and for the fulfillment of the mandatory HSSEMS procedures, all the Remediation contractors needs to report waste generation data from the various project activities on a monthly basis. Data on waste generation is collected in order to implement cost-efficient and sustainable waste management operations. Data analytics approaches can be built on the top of the data to produce more detailed, and in-time waste generation information for the basis of waste management and collection. The results obtained highlight the potential of advanced data analytic approaches in producing more detailed waste generation information for planning and optimization of waste collection and recycling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste" title="waste">waste</a>, <a href="https://publications.waset.org/abstracts/search?q=tencnolgies" title=" tencnolgies"> tencnolgies</a>, <a href="https://publications.waset.org/abstracts/search?q=KERP" title=" KERP"> KERP</a>, <a href="https://publications.waset.org/abstracts/search?q=data" title=" data"> data</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a> </p> <a href="https://publications.waset.org/abstracts/167411/kuwait-environmental-remediation-program-waste-management-data-analytics-for-planning-and-optimization-of-waste-collection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167411.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">113</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2626</span> Early-Warning Lights Classification Management System for Industrial Parks in Taiwan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Min%20Chang">Yu-Min Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuo-Sheng%20Tsai"> Kuo-Sheng Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Hung-Te%20Tsai"> Hung-Te Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Chia-Hsin%20Li"> Chia-Hsin Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the early-warning lights classification management system for industrial parks promoted by the Taiwan Environmental Protection Administration (EPA) since 2011, including the definition of each early-warning light, objectives, action program and accomplishments. All of the 151 industrial parks in Taiwan were classified into four early-warning lights, including red, orange, yellow and green, for carrying out respective pollution management according to the monitoring data of soil and groundwater quality, regulatory compliance, and regulatory listing of control site or remediation site. The Taiwan EPA set up a priority list for high potential polluted industrial parks and investigated their soil and groundwater qualities based on the results of the light classification and pollution potential assessment. In 2011-2013, there were 44 industrial parks selected and carried out different investigation, such as the early warning groundwater well networks establishment and pollution investigation/verification for the red and orange-light industrial parks and the environmental background survey for the yellow-light industrial parks. Among them, 22 industrial parks were newly or continuously confirmed that the concentrations of pollutants exceeded those in soil or groundwater pollution control standards. Thus, the further investigation, groundwater use restriction, listing of pollution control site or remediation site, and pollutant isolation measures were implemented by the local environmental protection and industry competent authorities; the early warning lights of those industrial parks were proposed to adjust up to orange or red-light. Up to the present, the preliminary positive effect of the soil and groundwater quality management system for industrial parks has been noticed in several aspects, such as environmental background information collection, early warning of pollution risk, pollution investigation and control, information integration and application, and inter-agency collaboration. Finally, the work and goal of self-initiated quality management of industrial parks will be carried out on the basis of the inter-agency collaboration by the classified lights system of early warning and management as well as the regular announcement of the status of each industrial park. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industrial%20park" title="industrial park">industrial park</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20and%20groundwater%20quality%20management" title=" soil and groundwater quality management"> soil and groundwater quality management</a>, <a href="https://publications.waset.org/abstracts/search?q=early-warning%20lights%20classification" title=" early-warning lights classification"> early-warning lights classification</a>, <a href="https://publications.waset.org/abstracts/search?q=SOP%20for%20reporting%20and%20treatment%20of%20monitored%20abnormal%20events" title=" SOP for reporting and treatment of monitored abnormal events"> SOP for reporting and treatment of monitored abnormal events</a> </p> <a href="https://publications.waset.org/abstracts/14144/early-warning-lights-classification-management-system-for-industrial-parks-in-taiwan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14144.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">326</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2625</span> On-Site Management from Reactive to Proactive </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Tzu%20Chen">Yu-Tzu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Luh-Maan%20Chang"> Luh-Maan Chang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Construction is an inherently risky industry.

Phosphorite mining activities generate vast amounts of waste, which pose significant environmental risks due to their contaminants. The proposed approach involved transforming these phosphorite residue tailings into valuable porous materials through a series of physico-chemical processes including milling, acid-base leaching, designing or templating as well as formation processes. The key components of the tailings were extracted and processed to produce porous arrays with high surface area and porosity. These materials were engineered to possess specific properties suitable for environmental remediation applications, such as enhanced adsorption capacity and selectivity for target contaminants. The synthesized porous materials were thoroughly characterized using advanced analytical techniques (XRD, SEM-EDX, N2 sorption, TGA, FTIR) to assess their structural, morphological, and chemical properties. The performance of the materials in removing various pollutants, including heavy metals and organic compounds, were evaluated through batch adsorption experiments. Additionally, the potential for material regeneration and reusability was investigated to enhance the sustainability of the proposed remediation approach. The outdoors of this research holds significant promise for addressing the environmental challenges associated with phosphorite residue tailings. By valorizing these waste materials into porous materials with exceptional remediation capabilities, this study contributes to the development of sustainable and cost-effective solutions for environmental cleanup. Furthermore, the utilization of phosphorite residue tailings in this manner offers a potential avenue for the remediation of other contaminated sites, thereby fostering a circular economy approach to waste management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functional%20porous%20materials" title="functional porous materials">functional porous materials</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphorite%20residue%20tailings" title=" phosphorite residue tailings"> phosphorite residue tailings</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20remediation" title=" environmental remediation"> environmental remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20solutions" title=" sustainable solutions"> sustainable solutions</a> </p> <a href="https://publications.waset.org/abstracts/181998/advancing-environmental-remediation-through-the-production-of-functional-porous-materials-from-phosphorite-residue-tailings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181998.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">59</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2623</span> Enzymatic Remediation in Standard Crude Palm Oil for Superior Quality Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haniza%20Ahmad">Haniza Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Norliza%20Saparin"> Norliza Saparin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmadilfitri%20Md%20Noor"> Ahmadilfitri Md Noor</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Suria%20Affandi%20Yusoff"> Mohd Suria Affandi Yusoff</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Enzymatic remediation is applied in low free fatty acid (FFA) (<4%) crude palm oil (CPO) to investigate if further FFA reduction is able to take place to produce premium CPO (<1% FFA). There are four different lipase Candida Antartica brands used in this study. Samples submit to enzymatic remediation using rotary evaporator under 100mbar vacuum with rotation at 260rpm. Samples were taken at 4hours, 8hours and 24hours for analyses. FFA less than 1% was achieved after 24hours reaction with 1% enzyme and 2% glycerol. The FFA reduction was intensified with the presence of glycerol who provides more sites for fatty acid attachment. At 2% glycerol, 71-88% FFA was reduced whereas at 1% glycerol, 46-75% FFA reduced. However, partial glycerides was increased with presence of glycerol with 2% add in glycerol showed greater partial glycerides increment compared to 1% glycerol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enzymes" title="enzymes">enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=crude%20palm%20oil" title=" crude palm oil"> crude palm oil</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20fatty%20acid" title=" free fatty acid"> free fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=glycerol" title=" glycerol"> glycerol</a> </p> <a href="https://publications.waset.org/abstracts/44575/enzymatic-remediation-in-standard-crude-palm-oil-for-superior-quality-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44575.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">322</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2622</span> Semiconducting Nanostructures Based Organic Pollutant Degradation Using Natural Sunlight for Water Remediation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Gupta">Ankur Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Jayant%20Raj%20Saurav"> Jayant Raj Saurav</a>, <a href="https://publications.waset.org/abstracts/search?q=Shantanu%20Bhattacharya"> Shantanu Bhattacharya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work we report an effective water filtration system based on the photo catalytic performance of semiconducting dense nano-brushes under natural sunlight. During thin-film photocatalysis usually performed by a deposited layer of photocatalyst, a stagnant boundary layer is created near the catalyst which adversely affects the rate of adsorption because of diffusional restrictions. One strategy that may be used is to disrupt this laminar boundary layer by creating a super dense nanostructure near the surface of the catalyst. Further it is adequate to fabricate a structured filter element for a through pass of the water with as grown nanostructures coming out of the surface of such an element. So, the dye remediation is performed through solar means. This remediation was initially limited to lower efficiency because of diffusional restrictions but has now turned around as a fast process owing to the development of the filter materials with standing out dense nanostructures. The effect of increased surface area due to microholes on fraction adsorbed is also investigated and found that there is an optimum value of hole diameter for maximum adsorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nano%20materials" title="nano materials">nano materials</a>, <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title=" photocatalysis"> photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20water%20treatment" title=" waste water treatment"> waste water treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20remediation" title=" water remediation"> water remediation</a> </p> <a href="https://publications.waset.org/abstracts/33109/semiconducting-nanostructures-based-organic-pollutant-degradation-using-natural-sunlight-for-water-remediation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33109.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">338</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2621</span> Electrokinetic Remediation of Nickel Contaminated Clayey Soils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waddah%20S.%20Abdullah">Waddah S.

Al-Sarem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrokinetic remediation of contaminated soils has undoubtedly proven to be one of the most efficient techniques used to clean up soils contaminated with polar contaminants (such as heavy metals) and nonpolar organic contaminants. It can efficiently be used to clean up low permeability mud, wastewater, electroplating wastes, sludge, and marine dredging. EK processes have proved to be superior to other conventional methods, such as the pump and treat, and soil washing, since these methods are ineffective in such cases. This paper describes the use of electrokinetic remediation to clean up soils contaminated with nickel. Open cells, as well as advanced cylindrical cells, were used to perform electrokinetic experiments. Azraq green clay (low permeability soil, taken from the east part of Jordan) was used for the experiments. The clayey soil was spiked with 500 ppm of nickel. The EK experiments were conducted under direct current of 80 mA and 50 mA. Chelating agents (NaEDTA), disodium ethylene diamine-tetra-ascetic acid was used to enhance the electroremediation processes. The effect of carbonates presence in soils was, also, investigated by use of sodium carbonate. pH changes in the anode and the cathode compartments were controlled by using buffer solutions. The results showed that the average removal efficiency was 64%, for the Nickel spiked saturated clayey soil.Experiment results have shown that carbonates retarded the remediation process of nickel contaminated soils. Na-EDTA effectively enhanced the decontamination process, with removal efficiency increased from 64% without using the NaEDTA to over 90% after using Na-EDTA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=buffer%20solution" title="buffer solution">buffer solution</a>, <a href="https://publications.waset.org/abstracts/search?q=contaminated%20soils" title=" contaminated soils"> contaminated soils</a>, <a href="https://publications.waset.org/abstracts/search?q=EDTA%20enhancement" title=" EDTA enhancement"> EDTA enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=electrokinetic%20processes" title=" electrokinetic processes"> electrokinetic processes</a>, <a href="https://publications.waset.org/abstracts/search?q=Nickel%20contaminated%20soil" title=" Nickel contaminated soil"> Nickel contaminated soil</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20remediation" title=" soil remediation"> soil remediation</a> </p> <a href="https://publications.waset.org/abstracts/76161/electrokinetic-remediation-of-nickel-contaminated-clayey-soils" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76161.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">245</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2620</span> Dry Binder Mixing of Field Trial Investigation Using Soil Mix Technology: Case Study on Contaminated Site Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mary%20Allagoa">Mary Allagoa</a>, <a href="https://publications.waset.org/abstracts/search?q=Abir%20Al-Tabbaa"> Abir Al-Tabbaa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study explores the use of binders and additives, such as Portland cement, pulverized fuel ash, ground granulated blast furnace slag, and MgO, to decrease the concentration and leachability of pollutants in contaminated site soils. The research investigates their effectiveness and associated risks of using the binders, with a focus on Total Heavy metals (THM) and Total Petroleum Hydrocarbon (TPH). The goal of this research is to evaluate the performance and effectiveness of binders and additives in remediating soil pollutants. The study aims to assess the suitability of the mixtures for ground improvement purposes, determine the optimal dosage, and investigate the associated risks. The research utilizes physical (unconfined compressive strength) and chemical tests (batch leachability test) to assess the efficacy of the binders and additives. A completely randomized design one-way ANOVA is used to determine the significance within mix binders of THM. The study also employs incremental lifetime cancer risk assessments (ILCR) and other indexes to evaluate the associated risks. The study finds that Ground Granulated Blast Furnace Slag (GGBS): MgO is the most effective binder for remediation, particularly when using low dosages of MgO combined with higher dosages of GGBS binders on TPH. The results indicate that binders and additives can encapsulate and immobilize pollutants, thereby reducing their leachability and toxicity. The mean unconfined compressive strength of the soil ranges from 285.0- 320.5 kPa, while THM levels are less than 10 µg/l in GGBS: MgO and CEM: PFA but below 1 µg/l in CEM I based. The ILCR ranged from 6.77E-02 - 2.65E-01 and 5.444E-01 – 3.20 E+00, with the highest values observed under extreme conditions. The hazard index (HI), Risk allowable daily dose intake (ADI), and Risk chronic daily intake (CDI) were all less than 1 for the THM. The study identifies MgO as the best additive for use in soil remediation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=risk%20ADI"
