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

Abstract

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. حازم جمعة محمود 46 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.
