Mechanisms for acquiring water chemistry in a coastal aquifer

Increasing water demand in the Bouteldja region has led to a systematic use of all the resources available in the-region, including on its borders. However, the development of anthropogenic activities and population expansion-in the Bouteldja region pose a risk to groundwater, which constitutes almost half of the resources mobilized. On the basis of the analytical results obtained for series of samplings (2006- 2013), carried out on the main measurement networks (wells, drilling and piezometers), we have tried to identify the main factors that influence the evolution of the physico-chemical parameters quality of water and to understand the degree of vulnerability of aquifer reservoirs. From these analytical data have been developed temporal evolution diagrams, spatial distribution maps, hydrochemical maps, and Principal Component Analysis PCA to illustrate the physicochemical evolution of water-in Bouteldja region.
