AbstractThe study was designed to evaluate the efficiency of two water treatment plants of drinking water in City of Kerbala as a model for the purification stations in Kerbala City- Province of Kerbala, and from December 2012 to May 2013,Many physio-chemical properties factors affecting water quality such as temperature, turbidity, conductivity EC, pH, dissolved Oxygen DO, biological demand oxygen BOD5, total dissolved substances TDS, total hardness, TH, nitrate NO3, phosphate PO4, sulphate SO4, Calisum Ca, magnesium Mg, potassium K, sodium Na and residual chlorine Cl. Also biological factors which included bacterial indicators for water pollution (total Coliform, fecal Coliform, fecal streptococci, Escherichia coli). Samples were collected monthly from six stations are H1,H2,H3, and R1,R2,R3 which represents source processing of crude water, sedimentation basin , basins final stages after chlorination in Al-Husain and Al- Hur water plant respectively.
The results showed the presence of fluctuation in most of the properties studied in both treatment plants, as well as the presence of greater numbers of bacteria than permissible limit environmentally counting months, indicating a defect in the purification process.
