Etude de la qualité de l’eau du barrage Mekheissia (Ain Témouchent)

Abstract

My research work consists first of all to study the evaluation of the quality of the waters of the Mekheissia by carrying out bacteriological and physicochemical analyzes. During this study I studied some bacteriological parameters, these are based on the research and the enumeration of the total germs (total coliforms and faecal coliforms and Escherichia coli), as well as the physico-chemical parameters which are mainly: temperature, pH, electrical conductivity, salinity, turbidity and hardness. The contents of the studied parameters of the Mekheissia dam water for drinking water exceed the maximum permissible values and in accordance with the Algerian standards, the dam waters show a poor aptitude for the production of drinking water. According to the results obtained, the Mekhaissia dam water is of acceptable quality for irrigation. Furthermore, bacteriological contamination in the dam water must be used with caution because it is not suitable for irrigation of all the cultures.
