Suivi des paramètres physico-chimiques et microbiologiques de la potabilisation des eaux de quelques sources dans la wilaya de Mila

Abstract

Water is the element necessary for life, because it is one of the most used materials in the fields of nutrition and hygiene, so it must meet quality standards. The objective of our work is to assess the physicochemical and bacteriological quality, as well as the quality and state of organic pollution, based on the Water Quality Index (WQI) and the Organic Pollution Index (OPI) of three water sources located in the province of Mila (Chigara, Mechira, and Ouled Khelouf). The study period spans three months, namely February, March, and April. Analyses were performed on these samples by measuring physicochemical parameters (temperature, pH, electrical conductivity (EC), turbidity, total hardness, calcium, phosphate, silicon, chloride, nitrite, and nitrate, etc.) and bacteriological analyses (total germs, total coliforms, fecal coliforms, sulfite-reducing Clostridum, etc.). The results showed that the water intended for human consumption is of good quality, with most of the analyzed parameters, both physicochemical and bacteriological, complying with the standards approved by the World Health Organization and Algerian standards. The water quality index also indicated that the water studied was potable. It should be noted that the Ouled Khelouf spring is excellent, while the Chigara and Mechira springs provide good quality water.
