Abstract


In this paper, we present the results of an experimental study of the effect of dissolved chemical pollutants existing in the wastewater from black wells on drinking water wells which drilled in unconfined aquifers. We observe the transport of pollutant from black wells to drinking water wells drilled in the area by collecting of several samples from drinking water well. The period between each two samples were 6 days and chemical analysis for collected water samples have been done in the laboratory. An investigation to the variation with time in the concentration of dissolved substance in black water well. It was found that the concentration of dissolved pollutants in pumping wells increases gradually with time till reaches the maximum level of concentration as that at the source of pollution (the black well), and it is not acceptable for drinking or use in the domestic purpose. Also it, was found that the degree of pollution of the pumping wells depends on the distance between the black well and pumping well and on the type of soil, also the pumping well in study area is not polluted by seawater intrusion because the typical seawater has a salinity of about 3500 p.p.m.
