Study of the properties of drinking water for Kirkuk city and its pollution in some areas

Kirkuk Technical Institute, Kirkuk, Iraq

Abstract

This study was conducted to demonstrate the difference between drinking water quality for seven different areas of Kirkuk city with the treatment water in the main and three sub storages tanks, affected with drinking water pipe lines, supplying system Alternate and continuous and also pipes across the construction work’s areas. The physical and chemical properties (turbidity, pH, conductivity, Alkalinity, Total hardness, calcium, magnesium, chloride, sulfate, TDS (Total dissolve solids), TSS (Total suspended solids), sodium and potassium) for raw water and treated water in the Storages in addition to the supplying water from seven different areas in Kirkuk were analyzed, samples taken at a rate nine times during the month of March. Results showed that Drinking water of Dumez, Wasti, Shorja, Imam Qasim and Arubaa polluted with turbidity with an average levels of (8.68, 6.04, 7.41, 6.95, 7.64) NTU respectively, over the limit allowed by IBWA (International Bottled Water Association), 2012 and WHO (World Health Organization), 2006. The turbidity in the main and sub storages have reached (4.04, 4.09, 4.47, 4.16) NTU respectively, while other physical and chemical properties were within the allowed limits for human use. The pollution in those areas caused by the alternative supplying system of treatment water and it has negative impact on the pipelines, it includes constriction work in areas also where pipelines exist.
