Abstract:
Our work under investigation is interested of quality physicochemical and bacteriological ground waters
in the area of the valley of M’Zab, in order to determine their aptitudes of use and the problems of
degradations posed.
Our adopted methodological approach consists to carry out for 12 wells and 16 drillings of
measurements physicochemical and bacteriological of groundwaters,as well as the classification of the
quality of water by report the standards.
The results of the analyzes carried out have shown that the waters of a large number of wells are of poor
quality both physico-chemically and bacteriologically, which probably constitutes a considerable danger to
the health of the populations consuming these waters. On the other hand, the contents of the
physicochemical constituents of the majority of these boreholes are in accordance with the standards of
potability. The classification of the boreholes indicates that they are of acceptable quality for irrigation or
half of the wells sampled are of poor quality, not generally suitable for irrigation.
