Study of qualitative properties of groundwater and its suitability for different uses in the Eastern of the Al- Dour city/ Salahaldin/ Iraq
A study was conducted to evaluate the groundwater in Abo- Dalaf Area, far east of Al-Dour city, Salahaldin governorate. The field work included, field visits to the area to know the geological reality and to identify the most important geomorphological and structural phenomena, then 10 wells were selected, distributed over the study area.
Laboratory work included physical and chemical tests of water samples, The physical characteristics included, Total hardness (TH), Total Dissolved Solid (TDS) Sodium Adsorption Ratio (SAR), Sodium Ratio (Na%), Temperature (T) and pH.
Chemical analyses, the main components of water samples, for Cations such as: Sodium (Na+), Potassium (K+), Calcium (Ca+2), and Magnesium (Mg+2), and Anions such as Chloride (Cl-), Sulfate (SO4-2), Bicarbonates (HCO3-), and nitrate (NO3-), and some trace elements were measured such as Iron (Fe), Copper (Cu), Zinc (Zn), lead (Pb), Nickel (Ni), Cobalt (Co), Chromium (Cr) and Cadmium (Cd). A location map of the study area was prepared using ArcGIS.The results showed a variation in the quality characteristics of groundwater in the study area. After comparing the results with local international standards, it was showed that the wells water of the study area was not suitable for human drinking, but suitable for irrigation except well (1).
