The study of the quality assessment of groundwater for the drinking of seven wells distributed in Kadam AL-jabal (Bdarna, Josh, Badr and Tigi) was highlighted in this research. A number of well water samples were collected during (2016), natural and chemical properties were assigned to these samples and elements were identified by the following: pH, TDS solids, EC Electrical conductivity, total hardness, calcium, magnesium, sulphate, potassium, sodium, results compared to standard water quality (who,2011), and (WQI-Water Quality Index), calculations were performed. The results found that the salt concentration in the studied wells increased, affecting water quality so that it was between poor and undrinking according to the quality index. Keywords: Groundwater, natural and chemical properties, standard water quality and water quality index.
