There had been occurrences of inadequate supply of water in certain cities and unexpected floods over the last few years. This paper discusses the results and efforts to clean the Gombak River which passes through several industrial areas and the City of Kuala Lumpur and the Penchala River which has an extra burden of passing through a highly densely populated Kuala Lumpur satellite city. Both rivers were considered polluted with the Penchala River being in a worse situation than the Gombak River. Special attention was given to the trends in the levels of Water Quality Index (WQI) over a period of nine years from 1997 to 2005. Results of efforts which included public participation, engineering and river works and strict statutory regulations by the government authorities had shown only slight success in improving the river water quality. The Gombak River started with a WQI of 64 units shows improvement of 0.07 WQI units / month while the Penchala River started with WQI of 27 units shows improvement of 0.017 units / month with BOD and Ammoniacal Nitrogen as critical factors. Further efforts from stakeholders could be harnessed and public awareness be enhanced to strive for a healthier Gombak and Penchala rivers.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Evaluating Trends of Water Quality Index of Selected Kelang River Tributaries","attachmentId":73014044,"attachmentType":"pdf","work_url":"https://www.academia.edu/58757232/Evaluating_Trends_of_Water_Quality_Index_of_Selected_Kelang_River_Tributaries","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/58757232/Evaluating_Trends_of_Water_Quality_Index_of_Selected_Kelang_River_Tributaries"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="3" data-entity-id="1812125" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/1812125/Water_Quality_Assessment_and_Associated_Stressing_Factors_of_the_Seti_River_Basin_Pokhara_Sub_Metropolitan_City">Water Quality Assessment and Associated Stressing Factors of the Seti River Basin, Pokhara Sub Metropolitan City</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="1167395" href="https://hkhbenso.academia.edu/DeepNarayanShah">Deep Narayan Shah</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of Hydrology …, 2011</p><p class="ds-related-work--abstract ds2-5-body-sm">The ASSESS-HKH Field Screening Methodology was carried out to assess the ecological river water quality status of nineteen small to medium sized rivers of the Seti River basin within Pokhara sub-metropolitan city during the lean flow period in March 2007. Multi habitat qualitative samplings for forty-six sites were conducted with 100 m stretch in each study river section. Five river water quality classes; class I (high), class II (good), class III (moderate), class IV (poor) and class V (bad) have been used to describe the effect of organic degradable pollution (saprobic approach). The response of benthic macroinvertebrates varied with organic pollution, sediment extraction and river crossings. The Harpan and Orlan (inlets) and Boksira (outlet) rivers of Phewa lake have water quality class III (moderately polluted) except Phirke river (outlet) which has class V. Most of the rivers outside the municipal boundaries have been identified as Class II indicating good water quality. The whole stretches of the Phusre and the Seti Rivers are still in good ecological condition. A total of 19 stressing factors have been identified along the river stretches, which have been grouped into five broad groups i.e., solid waste, effluent factors, activities and facilities, hydro-morphological degradation and ecological disturbances, and sanitation activity. The results are visualized by a colored water quality map which indicates the present ecological status of the Seti River basin. This map serves as an easy readable tool to identify hot spots and to show where immediate action is required. It also attracts the attention of the decision makers and enables timely measures to be taken for improving the deteriorating water quality of the rivers.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Water Quality Assessment and Associated Stressing Factors of the Seti River Basin, Pokhara Sub Metropolitan City","attachmentId":25028257,"attachmentType":"pdf","work_url":"https://www.academia.edu/1812125/Water_Quality_Assessment_and_Associated_Stressing_Factors_of_the_Seti_River_Basin_Pokhara_Sub_Metropolitan_City","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/1812125/Water_Quality_Assessment_and_Associated_Stressing_Factors_of_the_Seti_River_Basin_Pokhara_Sub_Metropolitan_City"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="4" data-entity-id="66188088" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/66188088/Analysis_of_Surface_Water_Quality_of_Four_Rivers_in_Jayapura_Regency_Indonesia_CCME_WQI_Approach">Analysis of Surface Water Quality of Four Rivers in Jayapura Regency, Indonesia: CCME-WQI Approach</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="1227026" href="https://independent.academia.edu/MarcelinoYonas">Marcelino Yonas</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of Ecological Engineering</p><p class="ds-related-work--abstract ds2-5-body-sm">In Indonesia, the river water quality has been determined based on Government Regulation of the Republic of Indonesia No. 22 of 2021. This study aimed to determine the quality of surface water from the Damsari, Jabawi, Kleblow, and Komba Rivers in Jayapura Regency based on the monitoring data from 2016 to 2019. The CCME-WQI method is used to determine the status of rivers based on river water quality standards (class 1 to class 4). The results of the study showed that the parameters of water temperature, TDS, pH, NH 3 , NO 3-, SO 4-2 , surfactant, oil/grease, Cr-(IV), Mn, Fe, Fecal Coliform, and Total Coliform were still in accordance with the quality standard. Meanwhile, TSS, COD, BOD, Total Phosphate, Hg, and Ni have exceeded the water quality standard, where the dominant pollutant source is an anthropogenic waste. On the basis of the WQI average value, the four rivers are not suitable as a source of drinking water (Poor-Marginal; 41.33-58.25). The Jabawi River can be used as a recreational facility, but it must be under special management (Fair; 69.75), while the other three rivers are not suitable (Marginal; 52.00-61.67). The Jabawi and Komba Rivers are in the Fair category (75.50 and 69.33) to support aquatic life, while the Damsari and Kleblow Rivers are in the Marginal category (59.00 and 61.25). The water quality of the four rivers is very good and suitable to be used as a water source for irrigation (Good category; 80.00-88.00). The strategies for controlling river water pollution and increasing the role of the government, stakeholders, and the community are needed.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Analysis of Surface Water Quality of Four Rivers in Jayapura Regency, Indonesia: CCME-WQI Approach","attachmentId":77478212,"attachmentType":"pdf","work_url":"https://www.academia.edu/66188088/Analysis_of_Surface_Water_Quality_of_Four_Rivers_in_Jayapura_Regency_Indonesia_CCME_WQI_Approach","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/66188088/Analysis_of_Surface_Water_Quality_of_Four_Rivers_in_Jayapura_Regency_Indonesia_CCME_WQI_Approach"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="5" data-entity-id="124235164" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/124235164/Pollution_Control_Strategy_to_Prevent_the_Degradation_of_River_Water_Quality_Case_Study_of_Talawaan_River_Minahasa_Regency_North_Sulawesi_Province_">Pollution Control Strategy to Prevent the Degradation of River Water Quality (Case Study of Talawaan River, Minahasa Regency, North Sulawesi Province)</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="125967655" href="https://wordperss.academia.edu/AlfaPongoh">Alfa Pongoh</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Jurnal Pembangunan dan Alam lestari, 2021</p><p class="ds-related-work--abstract ds2-5-body-sm">This research was conducted to analyze and describe the Pollution Control Strategy for Preventing Degradation in the Water Quality of the Talawaan River in Minahasa Regency, North Sulawesi Province.

On the other hand, river water is an important source of drinking water. Therefore, clean and safe water has become a priority program of the Government and is parallel with the international agreement known as the Sustainable Development Goals (SDGs). Rapid population growth and industrialization cause inadequate access to safe water; only 73% of Indonesian people can access safe water. This review paper aims to present a comprehensive discussion concerning water pollution in four big rivers, i.e., Siak, Citarum, Bengawan Solo, and Brantas Rivers, that have experienced pollution and provide alternative solutions to mitigate the pollution. Data were collected from related institutions, governments' regulations, the authors' experiences, and literature studies. Developing a riparian zone with multiple ecological services and introducing Internet of Things (IoT) devices that monitor and provide real-time water quality information is essential for mitigating river water pollution. Law enforcement is an alternative method to reduce point-source pollutants from industries. Non-point source pollutants from domestic and agricultural wastes may be reduced through spreading awareness and implementing personal and environmental hygiene, involving the community in designing, as well as monitoring and evaluating water quality. Those approaches should be accompanied by proper institutions, regulations, and policies.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Water Pollution of Some Major Rivers in Indonesia: The Status, Institution, Regulation, and Recommendation for Its Mitigation","attachmentId":117582120,"attachmentType":"pdf","work_url":"https://www.academia.edu/123056980/Water_Pollution_of_Some_Major_Rivers_in_Indonesia_The_Status_Institution_Regulation_and_Recommendation_for_Its_Mitigation","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/123056980/Water_Pollution_of_Some_Major_Rivers_in_Indonesia_The_Status_Institution_Regulation_and_Recommendation_for_Its_Mitigation"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="7825105" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/7825105/Water_Resource_Pollution_and_Impacts_on_the_local_livelihood_A_case_study_of_Beas_River_in_Kullu_District_India">Water Resource Pollution and Impacts on the local livelihood: A case study of Beas River in Kullu District, India</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="14527566" href="https://rivpolyonline.academia.edu/PriyaranjanMishra">Priyaranjan Mishra</a></div><p class="ds-related-work--abstract ds2-5-body-sm">Rivers are considered as the life line of any country since they make water available for our domestic, industrial and recreational functions. The quality of river water signifies the health status and hygienic aspects of a particular region, but the quality of these life lines is continuously deteriorating due to discharge of sewage, garbage and industrial effluents into them. Water demand has increased manifolds due to the increased population, therefore tangible efforts to make water sources free from pollution is catching attention all across the globe. This paper attempts to highlight the trends in water quality change of River Beas, right from Manali to Larji in India. This is an important river in the state of Himachal Pradesh and caters to the need of water for Manali and Kullu townships, besides other surrounding rural areas. The Manali-Larji Beas river stretch is exposed to the flow of sewage, garbage and muck resulting from various project activities, thereby making it vulnerable to pollution. In addition, the influx of thousands of tourists to these towns also contributes to the pollution load by their recreational and other tourist related activities. Pollution of this river has ultimately affected the livelihood of the local population in this region. Hence, water quality monitoring was carried out for the said stretch between January, 2010 and January, 2012 at 15 various locations on a quarterly basis, right from the upstream of Manali town and up to downstream of Larji dam. Temperature, colour, odor, D.O. pH, BOD, TSS, TC and FC has been the parameters that were studied. This study gives the broad idea about the characteristics of water at locations in the said river stretch, and suggestions for improving water quality and livelihood of local population in this particular domain.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Water Resource Pollution and Impacts on the local livelihood: A case study of Beas River in Kullu District, India","attachmentId":34326251,"attachmentType":"pdf","work_url":"https://www.academia.edu/7825105/Water_Resource_Pollution_and_Impacts_on_the_local_livelihood_A_case_study_of_Beas_River_in_Kullu_District_India","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/7825105/Water_Resource_Pollution_and_Impacts_on_the_local_livelihood_A_case_study_of_Beas_River_in_Kullu_District_India"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="24427394" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/24427394/River_water_quality_preliminary_rapid_assessment_using_pollution_index">River water quality preliminary rapid assessment using pollution index</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="30808780" href="https://bogoragriculturaluniversity.academia.edu/HefniEffendi">Hefni Effendi</a></div><p class="ds-related-work--abstract ds2-5-body-sm">A rapid interpretation of river water quality is a compulsory since river is a dynamic ecosystem, influenced by various activities in the river bank.

Hence, river water quality is an important parameter that must be preserved and monitored. As the state of Selangor and the city of Kuala Lumpur, Malaysia, are undergoing tremendous development, the river is subjected to pollution from point and non-point sources. The water quality of the Klang River basin, one of the most densely populated areas within the region, is significantly degraded due to human activities as well as urbanization. Evaluation of the overall river water quality status is normally represented by a water quality index (WQI), which consists of six parameters, namely dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, suspended solids, ammoniacal nitrogen and pH. The objectives of this study are to assess the water quality status for this tropical, urban river and to establish the WQI trend. Using monthly WQI data from 1997 to 2007, time series were plotted and trend analysis was performed by employing the first-order autocorrelated trend model on the moving average values for every station. The initial and final values of either the moving average or the trend model were used as the estimates of the initial and final WQI at the stations. It was found that Klang River water quality has shown some improvement between 1997 and 2007. Water quality remains good in the upper stream area, which provides vital water sources for water treatment plants in the Klang valley. Meanwhile, the water quality has also improved in other stations. Results of the current study suggest that the present policy on managing river quality in the Klang River has produced encouraging results; the policy should, however, be further improved alongside more vigorous monitoring of pollution discharge from various point sources such as industrial wastewater, municipal sewers, wet markets, sand mining and landfills, as well as non-point sources such as agricultural or urban runoff and commercial activity.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Trend analysis of a tropical urban river water quality in Malaysia","attachmentId":31197050,"attachmentType":"pdf","work_url":"https://www.academia.edu/3422899/Trend_analysis_of_a_tropical_urban_river_water_quality_in_Malaysia","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/3422899/Trend_analysis_of_a_tropical_urban_river_water_quality_in_Malaysia"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":107440751,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":107440751,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_107440751" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
