Abstract

A Water Quality Index (WQI) is a useful statistical tool for simplifying, reporting and interpreting complex information obtained from any body of water. A simple number given by any WQI model explains the level of water contamination. This study is carried out by using twelve ecological parameters in evaluating the quality of the ground water for drinking usage, by choosing four sampling sites in Kanasura and Kanigoma district located in Sulaimani city during 15 July, 2013 to 1 September 2013. The sampling was repeated after 15 days and the present study is spread over a period of two months of summer season. The present study aimed to calculate water quality index (WQI) by the analysis of twelve physico-chemical parameters on the basis of Weighted Arithmetic Index in order to assess the suitability of water for drinking purposes and other human uses. These physico-chemical parameters like Electrical Conductivity (EC), Turbidity, pH, Total Dissolved Solids (TDS), Calcium (Ca2+), Magnesium (Mg2+) ,  Total Hardness as CaCO3, Nitrate (NO3-_N), Nitrite, (NO2-_N), Sulfate (SO4 2-), Chloride(Cl-),  and Phosphate (PO43-_P). The observed values of these physico-chemical parameters were compared  with WHO standards. The results showed that water quality varied from good water to poor water range.
