los tanques de abastecimiento de la Facultad de Ciencias y Educación (sedes Macarena A y B), pertenecientes a la Universidad Distrital. Se tomaron ocho puntos de muestreo en las dos sedes, siendo prioritarios los grifos de los baños y los tanques del agua. En el laboratorio, se empleó la técnica de filtración por membrana y el medio selectivo Agar Chromocult para la detección de presencia de coliformes fecales. Los resultados en los parámetros fisicoquímicos del agua presentaron niveles de pH entre 7.2 y 7.5; mientras que los nitratos, nitritos, fosfatos y amonio fueron de cero (0 ppm) y el oxígeno disuelto se mantuvo entre 8.5 y 9 mg/L.Lo anteriorevidenció que el agua, en las sedes mencionadas, es apta para el consumo humano. Sin embargo, se hace necesario tomar medidas preventivas para el uso adecuado de los espacios físicos en lavamanos y grifos destinados al acceso directo del agua de consumo.</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":"Determinación de indicadores de contaminación fecal (coliformes fecales) en los tanques de abastecimiento de agua de la Universidad Distrital Francisco José de Caldas Sedes Macarena a y b","attachmentId":67548562,"attachmentType":"pdf","work_url":"https://www.academia.edu/49160967/Determinaci%C3%B3n_de_indicadores_de_contaminaci%C3%B3n_fecal_coliformes_fecales_en_los_tanques_de_abastecimiento_de_agua_de_la_Universidad_Distrital_Francisco_Jos%C3%A9_de_Caldas_Sedes_Macarena_a_y_b","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/49160967/Determinaci%C3%B3n_de_indicadores_de_contaminaci%C3%B3n_fecal_coliformes_fecales_en_los_tanques_de_abastecimiento_de_agua_de_la_Universidad_Distrital_Francisco_Jos%C3%A9_de_Caldas_Sedes_Macarena_a_y_b"><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="9" data-entity-id="51256166" 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/51256166/Contaminaci%C3%B3n_fecal_del_agua_superficial_de_la_Microcuenca_del_R%C3%ADo_Purires_Costa_Rica_2010_2011">Contaminación fecal del agua superficial de la Microcuenca del Río Purires, Costa Rica. 2010-2011</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="48929587" href="https://ucr.academia.edu/LuzChac%C3%B3nJim%C3%A9nez">Luz chacon</a></div><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":"Contaminación fecal del agua superficial de la Microcuenca del Río Purires, Costa Rica. 2010-2011","attachmentId":69054916,"attachmentType":"pdf","work_url":"https://www.academia.edu/51256166/Contaminaci%C3%B3n_fecal_del_agua_superficial_de_la_Microcuenca_del_R%C3%ADo_Purires_Costa_Rica_2010_2011","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/51256166/Contaminaci%C3%B3n_fecal_del_agua_superficial_de_la_Microcuenca_del_R%C3%ADo_Purires_Costa_Rica_2010_2011"><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":83805839,"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":83805839,"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_83805839" 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.
