Water quality evaluation of the river Tislit-Talsint (East Morocco)

In this paper we gave an assessment of the water quality of the river (Tislit-Talsint in the east morocco), water samples of the river were made during two campaigns during a dry period (May/2011). The physicochemical analysis results, presented in this work, showed that the pH values measured in the river waters put them in the class excellent to good surface water, thus low mineralization due to the low conductivity with an average of 850 μs/cm. Nitrate Analysis shows that nitrate levels are extremely low; the sulfates values are conform to the WHO standards (250 mg/l). In all study stations, the levels found in potassium ion, meet the WHO standard (12 mg/l), except the station SR1 (21.85 mg/l) has a high content of this element. At the end of this study, it can be argued that the use of the Tislit-Talsint river water without treatment could be a significant health risk.
