We studied the vulnerability and risks of pollution of the alluvial aquifer of Tebessa-Morsott that ranks amongst the major groundwater reservoirs of the region. The method used to assesgroundwater vulnerability was the DRASTIC method, based on seven parameters that affect andcontrol the groundwater flow: Depth to groundwater, Impact of the unsaturated zone, net recharge,aquifer media, hydraulic conductivity, soil media, topography. These parameters were obtained fromdata field, synthetic maps relative to the area considered and then identified within each cell afterdiscretization of the studied area in regular square cells. For each cell, DRASTIC rating for eachparameter was multiplied by the DRASTIC weight for that cell and summed to determine theDRASTIC index. A detailed vulnerability map was obtained, showing four classes of potentialpollution of the aquifer. Check analysis of the quality of groundwater within these zones are carriedout in order to assess the risks of contamination. Pollution by nitrates occurs especially in the wells oflow depth, but also in certain drillings for drinking water, whereas bacteriological pollution is observedonly in the domestic wells. |
