Assessment of the Quality of Tap Water Intended for Potability Using the IQE Water Quality Index Case of the Municipality of Sendjas (Algeria)

Abstract

Water quality is an important criterion for meeting water demand and supply. Ensuring freshwater quality that meets human and ecological needs is therefore an important aspect of integrated environmental management and sustainable development. The objective of this study is to monitor and evaluate the quality of the water distributed to the municipality of Sendjas from the Sidi Yakoub dam to the consumer using the index of water quality which includes 10 parameters. (PH, TDS, nitrate, sulphate, bicarbonate, chloride, calcium, potassium, sodium and magnesium). Physico-chemical analyses were carried out on samples taken from the Sidi Yakoub dam, a reservoir which distributes water to the municipality of Sendjas called reservoir 500, and a sample from the house of one consumer directly from the tap. The results of the analyses obtained during our work show that there is a slight difference in the latter, but the quality of the physico-chemical water remains good and consumable at the level of two stations (Sidi Yakoub Dam, Reservoir 500) and Bad quality of the station which represents the municipality of Sendjas, the latter is due to the high content of chloride and the degradation of distribution networks.
