Contamination by nitrate was found in all samples (from wells and pumps). As many as 80%of the water samples contain nitrate concentration exceeding the 45 mg l -1 standard for safedrinking water recommended by the United States Environmental Protection Agency (EPA). Eight of the examined ten samples display NO - 3 ranging from 57-120 mg l -1 . The nitratecontents in the remainder two samples (34 and 35 mg l -1 ) are slightly lower than the standardlimit.Such contamination of water by nitrate, reaching up to more than two times higher than thepermissible limit, is considered to be a serious environmental and public health concern,where various health risks and toxicity can arise.Natural levels of ammonium (NH + 4 ) in ground and surface water are usually low. Higherconcentrations can be used as well indicator of anthropogenic pollution including sewageand animal wastes.The elevated contents of nitrate (NO 3 ) in studied ground water should be of anthropogenicsource, where no nitrate –bearing components are recorded in the subsurface fluviatile Nilebasin sediments. The reported concentrations of ammonium are extremelyhigher than the naturally documented levels; and thus probably of anthropogenic parentage.The contemporaneous enhancement of NO - 3 and NH + 4 in ground water from the two sitesconfirms this conclusion
