BARRERA CASTILLO, Violeta Victoria et al. Discharge of domestic wastewater and the degree of contamination of the Pisco River, Ica. Rev. Inv. Cs. Agro. y Vet. [online]. 2024, vol.8, n.24, pp.916-929.  Epub 20-Sep-2024. ISSN 2664-0902.  https://doi.org/10.33996/revistaalfa.v8i24.313.

Introduction: The discharge of domestic wastewater into surface water bodies, such as rivers, lakes and oceans, constitutes one of the most serious environmental problems worldwide. The objective was to verify the discharge of domestic wastewater contributes to the degree of pollution of the Pisco River, Ica, 2023. Materials and methods: The approach is quantitative, descriptive type, the design is experimental-cross-sectional. Standardized sampling techniques were used to collect water samples at different times of the year. Analyses of "biochemical oxygen demand (BOD), total suspended solids, total coliforms", among other indicators, were performed using methods recognized in the scientific field. Results: they revealed that the concentrations of the evaluated elements are within the acceptable limits established by environmental regulations. The BOD suggests a controlled load of organic matter, and the concentrations of suspended solids and total coliforms are below the critical thresholds. Discussion: The findings highlight the importance of continuous monitoring and the need to implement preventive measures in the event of possible changes in the conditions of discharge of residual household fluids. The relevance of public awareness about sustainable practices and collaboration between government entities, local communities and industrial sectors to preserve the Pisco River and its aquatic ecosystem in the long term was highlighted. Conclusions: This study provides a comprehensive view of the nature of the fluid in the Pisco River, evidencing relatively healthy environmental conditions at the selected sampling stations, but underlining the importance of maintaining conservation and sustainable management efforts.
