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

We propose in this study to proceed with sampling wastewater at the three collectors Oued R’dom from upstream (Bab tissra) to downstream (Zirara) through the domestic center of the city of Sidi Kacem. The sampling was carried out twice a month over a period of five months (January, February, March, April and May). We used the technique Bailenger amended by [1]. At the upstream percentages of positive samples helminth eggs found in wastewater are: Nematodes 30%, 20% and 10% Ascaris sp, Trichuris sp, Enterobius vermicularis for Cestodes 30% Taenia. Sp and the eggs and larvae of strongyles 30%. At the home collector (C) nematodes are represented by the eggs of Ascaris sp, 60%, followed by Tri-churis sp. 40% for Enterobius. Vermicularis eggs sp. représentent 20% of the class Cestoda with percentages of positive samples for Taenia sp 30% and 10% for Hymenolepis. sp. is isolated from cyst protozoan Entamoeba coli 10% for eggs, and larvae of strongyles 60% presented in the wastewater at the Downstream class nematodes is 70% with 40% of Ascaris sp, and 30% Trichuris sp. la class Cestoda is represented by 30% of Taenia. Sp. et Hymenolepis’s. Sp. 10%. For eggs and larvae of strongyles is 40%. Exceeding the WHO standards, these parasites pose a potential hazard to the direct and indirect use of wastewater from the town of Sidi Kacem.展开更多
