Valuation of water quality for drinking and domestic purposes using WQI : Acase study for groundwater of Al-Gameaa and Al-Zeraee qaurters in Mosul city/Iraq

Abstract

The current study aims to assess the groundwater quality of some area in the left side of Mosul city, the samples were collected randomly from 11 wells (five replicates from each well), to measure the physicochemical and bacteriological properties using weighted mathematical model (WQI). The results indicated that the studied groundwater were ranged from poor to unsuitable qualities for drinking and domistic purposes. This deterioration in water quality is due to as a result of the high levels of electrical conductivity, total hardness, sulfate ions, total number of bacteria and faecal coliform bacteria, which reached 3605 μS. Cm-1, (2760, 477) mg. l-1, 8.0 ×103 cell. ml-1 and 16< cell. 100ml-1 respictively.
