摘要：The quality of water resources in Morocco is degraded by pollution from agriculture, industry and urbanization. In this work we have realized a comparative study of three groundwater pollution sites: Mohammedia, Temara and Dar Bouazza. In general, the results of this study showed that most water wells are strongly mineralized as the conductivity far exceeds the standard of drinking water. Sodium chloride (NaCl) concentration is between 300 and 4000 mg / l and shows some of the wells are loaded with salts. These wells are ready for the old Mohammedia dump to be built in the industrial zone. The basic pH is generally in all wells.Pollution by nitrates three regions showed that the ground water is strongly affected Mohammedia terms of the permeability of the soil of the city. The concentration of nitrate can reach high values compared to the results obtained on the ground water at Temara and Dar Bouazza whose nitrate concentrations around 100 mg/l. Further pollution of groundwater in the three regions of the shows values of organic matters that go far beyond the standards of drinking water.
