摘要：In this study, the assessment of surface and ground waters quality in Tensift region during the period of 2003 to 2012 (9 years) was investigated. For surface waters, the results show that the five dams in the study area are distributed mainly in three facies, Ca-Na-HCO 3 -Cl-SO 4 , Ca-HCO 3 -SO 4 and Ca-HCO 3 -Mg facies. According to Moroccan water quality evaluation systems of 2002 and 2008, the quality is generally medium and good respectively. The trophic status of dams' waters studied is relatively varied, this variation shows a tendency to eutrophication. In most dams, Chlorophyceae, Diatoms, Cyanophyceae and Dinophyceae classes are the most dominant. These classes exhibit high algal production. During the investigation period, water quality of six treatment plants studied is consistent with the Moroccan standard of water quality for human consumption. For ground waters, the majority facies are Ca-Na-HCO 3 -Cl-SO 4 facies. Excellent and good classes are the dominant quality classes for these waters in the study area.
