Application of the CCME WQI to Evaluate Water Quality for Drinking Purpose: A Case Study for Groundwater Quality of Al-Mahalibiyah SubDistrict, Nineveh Province/ Iraq.

Abstract

The current study aims to applying the Canadian water quality model on water of twelve wellsdistributed in Al-Mahalibiyah sub district, north-west of Mosul, to be evaluated for drinkingpurposes, Monthly water samples were collected from each well, (From June to December 2012) toestimate the followings: PH, Total dissolved solids, Total Hardness, Total Alkalinity, Anions andCations concentrations.The results indicated a rise in some studied characters, especially Total dissolved Solid,Calcium and sulfate ions, that reached to (33909.673, 2271) mg / L, respectively, which have anegative impact on the CCMEWQI values, which ranged between (42.41 - 60.45) and this indicatesthat %83 of the water samples were classified as Marginal water category and the rest wereclassified as Poor water quality of drinking, this deterioration in water quality reflects the nature of the geological formations that water passes through, which requires some treatments such asfreezing and slow melting to improve their quality before drinking.
