Evaluación fisicoquímica y bacteriológica del agua del río chillón

Water is one of the most important and abundant compounds in the ecosystem. All living organisms on earth need water for their survival and growth. Until now, only the Earth is the only planet that has about 70% water, but of it only a very small percentage (0.3%) is suitable for human consumption. Additionally, the increased demand for water as a result of population growth, agriculture, and industrial development has forced environmentalists to determine the chemical, physical, and biological characteristics of natural water resources. The quality of water resources depends largely on physical-chemical parameters and biological characteristics. Evaluating the monitoring of these parameters is essential to identify the magnitude and source of any contaminant load. The availability of good quality water is an essential feature to prevent diseases and improve quality of life. In this article, the quality of the water was evaluated from the physicochemical and bacteriological point of view of the Chillón River located 130 km south of the city of Lima, Peru. The results concluded that the Chillón River, especially downstream, does not meet the quality standards established according to regulations. The ICARHS calculation was 35.40, which categorizes the Chillón River as having poor quality water. With the results obtained, it is recommended that government authorities and institutions support the continuation of river water monitoring as an effective tool to assess their ecological status, as well as to protect against contamination and human health.
