Hydrochemical Evaluation Of Water Resources In Khanaqin Area, Northeast Iraq
Abstract
The groundwater, surface water and Rainfall evaluation has been carried out in Khanaqin area in Diyala governorate to the east of Iraq. The analyzed hydro chemical parameters such as pH, electrical conductivity, total dissolved solids as well as cations and anions are used to describe groundwater, surface water and Rainfall quality and its suitability for different purposes. The study area covers (600) km2 .The main aquifer in the studied area is the Quaternary deposits which is of unconfined to semi-confined types. In some places of the area it extends within Quaternary–Bai Hassan Formation. (33) samples were sampled during 2013-2014 during water surplus and water deficit periods. The highest and lowest water levels of Al- Wand River for the studied year, (January 2013 to December 2013) were 177.9 m a.s.l (January) and 177.0 m a.s.l ( May to September) respectively. Water type of the most rainwater samples is of Ca-Na-Chloride, whereas the surface water type shown to be of Ca-Bicarbonate at the two study periods. Groundwater type of low and high level periods were Na-Mg-Chloride and Na-Ca-Sulfate respectively.
