Evaluating Water Quality of Beni-Haroun Dam (Northeastern Algeria) Before and After Treatment Procedures

Water treatment plants are of great importance in order to provide drinking water to the population. The present work aimed to study the quality of treated water from the Beni-Haroun dam (northeastern Algeria) through the analysis of its physicochemical and bacteriological parameters in order to ensure they conform to international standards. Physicochemical and bacteriological parameters of untreated water were also analysed and then compared to the same physicochemical and bacteriological parameters obtained after applying treatment procedures in order to evaluate the efficiency of these procedures on the water quality. As a result, the physicochemical parameters of treated water Beni-Haroun dam were revealed in concordance with the established international standards. Concerning bacteriological results, despite the presence of certain microorganisms in some analysed samples, their loads remained very low and do not constitute a major health risk. Based on our analyses, treated water from Beni-Haroun Dam remains generally of good quality.
