Abstract :
The aims of this study is to assess the quality of surface and groundwater resources in Ajdir commune. The studied area is characterized by a cracked soils composed of alternating marl-calcareous-sandstone layers. The Ajdir population used groundwater for agricultural and domestic uses. Accidental contamination of water resources as a result of anthropogenic activities will be a human disaster. Field investigation showed the presence of agricultural activity, car paint shop and car washing units and a controlled landfill (CL). The results of physico-chemical characterization indicate that the surface water and groundwater are chloride-sodium and potassium or sulphate-sodium types. The COD of surface water samples taken upstream and downstream of the CL varies between 153.6 and 249.6 mg / l, indicating an organic contamination. Water samples of some wells used for agricultural and human comsumption show high concentration of nitrates and contamined by Coliforms and Enterococci. Disturbing concentration of mercury (6.21 μg.L^-1) was detected in groundwater around tolerie and car washing activities . The use of water for human consumption and agriculture in the Ajdir region should be monitored.
