This research was conducted during the year of 2009 to evaluate the (WQI) for some wells at Al- Ba'aj district in Mosul city.

The study has been carried out to determine suitability of groundwater for drinking.

(WQI) was examined by analyzing of the following parameters: pH, total hardness, calcium, magnesium, chloride, total dissolved solids and sulphate.

The (WQI) for examined wells ranges from 43.56 to 941.91 which indicated that 6% of water wells was (excellent), 28% (good), 33% (poor) and 33% was (unsuitable) for drinking due to the high value for (WQI) was due to high values of total hardness, calcium, chloride, total dissolved solids and sulphate in the groundwater.

The results of this research recommend an intensive treatment before using the examined water for drinking shows the necessity of conducting primary treatment and disinfection consumption for the wells that can be used as a source of drinking
