Physicochemical quality of the water table of temara the salted rabat region kenitra, Morocco

Abstract

Water is a vital element for the development and maintenance of life on our planet, for which it is necessary to preserve and ensure the continual persistence of water, not only to provide man with a sufficient quantity for these needs but to assure him an ir upright quality of this water. The main objective of this work is to evaluate the physicochemical quality of the water of the Temara water and the comparison of this quality with Moroccan and international standards. Physico-chemical analyzes showed true variations in the different parameters studied, related to the impact of agricultural activities. The physicochemical characterization of the samples revealed a pH close to neutrality and relatively high salt contents. The chloride content was between 14.20 and 958.5 mg / l. For nitrate and nitrite load varies and 0.5 mg/L and 5.7 mg / L. These parameters of pollution were relatively high, compared to the average concentrations usually met for Moroccan drinking .The results obtained clearly exceed the standards of WHO (World Health Organization). Effluents therefore constitute a health risk. In conclusion, the pretreatment of these waters is strongly recommended.
