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

Abstract

The present work, deals with hydrochemistry and water quality of someshallow wells in Wana area, northern Iraq and its validity for irrigation, throughthe physical and chemical analyses of 13 water samples selected from these wellsdistributed in the study area.حازم جمعة محمود46The results revealed that there are two factors controlling the hydrochemistryof water in the area. The first is natural factor represented by type of rockcomponents of the studied area, and the second is anthropogenic factor which ishuman activities. Owing to the natural factor, the analyzed water tend to be of noncarbonate hardness by the influence of the evaporates of Fat'ha formation. Despitethe great influence of Fat'ha formation rocks on water quality in the area, howeverthe direct feeding of Tigris river to the well waters prevents the increasing of theconcentration of ions and this made these waters valid for irrigation purposes.
