ASSESSMENT OF MICROBIAL AND CHEMICAL LOAD OF SOME DRINKING WATER PLANTS INTAKES IN GREATER CAIRO

Abstract

River Nile is the main source of fresh water for domestic, agriculture, industry, fisheries and tourism purposes for most governorates in Egypt. Unfortunately, the drinking water plant intakes on River Nile is impacted by increasing concentrations of pollutants resulted from the agricultural drains located along its sides, industrial effluents and domestic waste from villages which have no sanitation system. This study aims at monitoring Total coliform, E.coli, algae which may be related with the risk of diarrheal diseases and other diseases if they are present in water. Also, suggesting limits for them in the criteria of drinking water plant intakes at Article 49 from decree No. 92 of 2013 in law No. 48 of 1982 for the protection of River Nile from pollution. Also to monitor microbiological and chemical water quality and expect any early water deterioration that will facilitate the solution before aggravate the problem.
