Hydrochemistry and Water Quality of Some Wells Distributed at Wana Area Northern Iraq

The present work, deals with hydrochemistry and water quality of some
shallow wells in Wana area, northern Iraq and its validity for irrigation, through
the physical and chemical analyses of 13 water samples selected from these wells
distributed in the study area.

The results revealed that there are two factors controlling the hydrochemistry
of water in the area. The first is natural factor represented by type of rock
components of the studied area, and the second is anthropogenic factor which is
human activities. Owing to the natural factor, the analyzed water tend to be of non
carbonate hardness by the influence of the evaporates of Fat'ha formation. Despite
the great influence of Fat'ha formation rocks on water quality in the area, however
the direct feeding of Tigris river to the well waters prevents the increasing of the
concentration of ions and this made these waters valid for irrigation purposes.
