| dc.description.abstract | Water quality in the Taghrist region, located in northeastern Algeria, on the northern slopes of the Aurès massif, has suffered a serious deterioration in recent years due to uncontrolled discharge of urban wastewater, the intensive use of chemical fertilizers in agriculture and overexploitation. This study aims at analyzing the functioning of the Mio-Plio-Quaternary aquifer, determining its current characteristics and understanding the mineralization processes involved in its chemical quality. Physico-chemical analyses were carried out on 34 water samples from the Mio-PlioQuaternary surface aquifer. The dominant chemical facies is of the bicarbonate calcium type. The electrical conductivity of the water has an average value of 974.75µS.cm-1. It should be noted that borehole P4 has an electrical conductivity of 3948 µS.cm-1. The descriptive analysis shows that the salinity of the water is highly variable from one place to another and increases in the direction of water flow, influenced by water-rock interaction, mineral dissolution and precipitation, base exchange and anthropic activity. A vulnerability map to water pollution has been drawn up by the GOD method, The map shows three zones of different degrees of vulnerability, A low vulnerability (29%) occupies the center of the area at the bottom of the Dj mountains. Chelia and Dj. Dalaa and a high to very high vulnerability extends from the northeast to the southwest of the plain and represents 71% of the region. | |
