The problem of pollution affects the whole world groundwater. The purpose of our
present study is to evaluate the impact of contamination from residues of
industry and agriculture, and discharge of untreated domestic wastewaters on
the physical, chemical, metal and bacteriological water quality of
Maamora’s
tablecloth (
Sebou bassin, Kenitra, Morocco). The
physicochemical parameters followed are: T ℃, pH, EC, NH

and fecal coliforms, faecal streptococci and total and faecal germs of raw
water from the boreholes. The physical, chemical, metal and bacteriological
quality shows that the groundwater which is used as drinking water in the city
of Kenitra and adjacent towns is generally good. However, high concentrations
of nitrates (over 210.8 mg/L) and other metals (185 μg/l for lead; 58.98 for nickel;
187.3 μg/L for iron; 2204 μg/L for zinc) in some wells are worrisome because of
the serious health consequences.
