Abstract
El-Moheet drain represents the main drainage system in El Minia district. It was selected as a case study in El Minia district. El-Moheet drain receives all waste water e.g. agricultural, domestic, and sewage from lateral minor drains. These wastes represent a source for contamination to the surface water which will be extended to the ground water aquifer through a seepage process.
The maximum industrial units in the selected areas also discharge their effluents directly into El Moheet drain and the seepage taking from the effluents as well as other anthropogenic activities impair the quality of surface and ground water and making them unfit for irrigation and drinking purposes. So, the treatment of the effluents before disposal into the drain should be practiced in all industrial premises of the district to safeguard better water quality.
The main task of this work is delineation the contaminated boundary around El-Moheet drain. For achieving propose Self potential and electrical resistivity measurements were carried out in a form of profiles perpendicular to the drain. Chemical analyses for trace and major elements were carried out for 28 water samples collected from the drain and drilled wells around it. Surface water from El Moheet drain and ground water samples exhibit substantial concentrations of trace elements. The electrical data were processed and interpreted through iteration process by using IX1D V3 software. It can be noticed that the contaminated zone was characterized by higher bulk electrical conductivity, positive SP anomaly. This zone is perpendicular to El –Moheet drain in nearly E-W direction with wide reached to more
than 150 m. Management waste water in El-Moheet drain is strongly recommended for further protection of the groundwater aquifer.
