Hydrochemical of Groundwater and Determining Its Quality and Suitability for Different Uses in Selected Wells in Khazraj Area/East of Dujail District / Salah Al-Din/Iraq

  • Riyadh M. Rashid


The groundwater quality was assessed and determined its validity for domestic and irrigation purposes. Where samples of groundwater were taken in 20 wells distributed over the study area, and the physical characteristics in the field were analyzed, represented by total dissolved salts (TDS), electrical conductivity (EC), pH, and temperature (C°). The main positive ions are represented by (calcium Ca+2, magnesium Mg+2, sodium Na+, potassium K+) and the main negative and represented ions (chlorides Cl-, sulfate SO4-2, bicarbonate HCO3-, nitrate NO3-) and the trace elements and represented were analyzed. (Cadmium, lead, iron, copper, nickel, and zinc), as well as the total hardness (T.H.), the sodium adsorption rate (SAR) and the percentage of dissolved sodium (Na(%. Where the results of the chemical analyzes indicated that there are several sources of nutrition that work on feeding groundwater in the study area, represented by the Ishaqi project, which is one of the sources of nutrition in the area, as well as the irrigation channels that are widely spread in the study area, as well as sewage and rainwater, all of these sources are considered sources of nutrition for the water study area, Where these sources worked to decrease the concentrations of the elements, to nourish them, raise their level and reduce their concentrations, and the groundwater of the study area was classified as of the type (Fresh Water and Slightly Water(It also showed a comparison of the results of the analyzes of groundwater with the specifications of the validity of using groundwater for different purposes, as it showed that the water of the region is not suitable for human drinking when compared to the Iraqi specifications and falls within the permissible limit when compared with the specifications of the World Health Organization. And it is suitable for drinking animals to a very good degree, as well as suitable for irrigation regardless of the small percentage of the magnesium element, as it is likely to increase its percentage above the permissible limit to the use of chemical fertilizers in those areas because they are dense agricultural areas.
