Análisis Químico de aguas residuales vertidas en los efluentes Burro, Manta y Muerto que desembocan en las playas de la parroquia Tarqui y los Esteros, Manta.

Abstract

The present study evaluated the quality of wastewater discharged into the effluents of the "rivers" Burro, Manta, and Muerto in Manta by comparing them to the maximum permissible limits for discharges into marine bodies. Samples were collected over 14 weeks at intervals of 3 consecutive days in each study area, using pre-sterilized 1-liter amber bottles. The Muerto effluent showed the highest levels of COD, followed by the Manta and Burro. Regarding TDS, the "river" Manta showed the highest levels in May-June, while the pH was similar across all rivers, indicating generally alkaline conditions. Finally, for the Temperature parameter, there were significant differences between rivers, with high variability within each river (25°C - 35°C). It is noteworthy that the effluents of the "rivers" Muerto and Manta are the most contaminated due to wastewater discharges, suggesting urgent measures to reduce pollution.
