Abstract:
The objective of this study is to evaluate the physicochemical quality of groundwater in the M'Zab valley intended for human consumption and irrigation because of the impact of their quality on public health. The analysis of the physicochemical quality is about samples taken from 16 holes of the deep aquifer and 12 wells of the surface water, distributed along the Oued M'Zab River from upstream to downstream. The results of the carried out analyzes have shown that the waters of the deep aquifer have a better quality than that of the waters of the superficial aquifer. The contents of the physicochemical constituents of the majority of the boreholes match the standards of potability according to WHO especially for pH, NH4+ and NO3-. On the other hand the waters of the superficial aquifer have a quality different from that of the waters of the deep aquifer. The waters of a large number of wells are of poor quality often exceed the thresholds of potability, this concerns more particularly the EC and the NO3-, which constitutes undoubtedly a risk for the inhabitants consuming these waters. Continuous assessment of the quality of these waters and treatment to reduce excessive concentrations of pollutants that may affect human health are strongly recommended. This preserves the quality of the groundwater and protects against all forms of pollution.
