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 two groundwater pollution zones: M’nasra (Kenitra) and Sfafaa (Sidi Slimane). 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 33.9 and 1184.6 mg / l and shows some of the wells are loaded with salts. The pH is generally basic in all wells. Pollution by nitrates two regions showed that the ground water is strongly affected M’nasra zone 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 Sfafaa zone whose nitrate concentrations around 20 mg/l. Further pollution of groundwater in the two regions of the shows values of organic matters that go far beyond the standards of drinking.
