Household waste. Leachate can be considered among the potential sectors that can contribute to the degradation of water quality and soil. To this end, we selected physico-chemical inorganic elements like indicator of pollution in the neighboring groundwater discharge of the water table in the region of Ouled Berjal to assess the quality of the region’s water wells in M’nasra. The wells in full discharge have a very high pollution levels and water collected from wells located right near the discharge of Ouled Berjal shows lower levels of contamination. So the well water away from the landfill is quite low compared to the other groups.展开更多

Therefore, when issued by a host, they result in sudden and drastic changes in the environment. This study aims at bacteriological characterization of the effluent from the provincial hospital in Sidi Kacem. And it shows that the effluent from the hospital contributing to non-regulatory standards ultimately reaches the environment (river wadi floor, animal, vegetable...). The results of bacteriological analyses (Total Coliforms, Fecal Coliforms) about sewage from the provincial hospital depending on the day of rest and work in the city of Sidi Kacem are presented with means respectively 557 × 104 and 328 × 104 in the rest and working days 555 × 104, 342 × 104 and the much higher maximum working days from the day of rest are 64 × 105 and 42 × 105. The results obtained show that the rate of bacteria (CT-CF) exceeds standards recommended by CNS (1994) and WHO (1996, 1997). These results have adverse effects on human life, animal, environment and ecosystem in general.展开更多
