The physical and chemical properties for the water of three wells in the Kharab Bazar village of Al-Baaj district in Nineveh Governorate were studied to determine its suitability for drinking, animal consumption and domestic uses, as groundwater is the main water resource in Al-Baaj district. Well water samples were collected monthly from October 2021 to March 2022, It included the measurement of some the physical and chemical properties: turbidity, electrical conductivity (ec), total dissolved solids (TDS), salinity, dissolved oxygen (DO), total hardness, calcium hardness, magnesium hardness, chloride (Cl-) and sulfates (SO4-2).
The results of this study showed the increase and decrease values of some physical and chemical properties, including turbidity, which ranged between (0-9.88) N.T.U in wells 1,2,3 respectively, and total dissolved solids (TDS) that ranged between 383-262 mg/L in well3, and EC reached (766-523) μS/cm in well3, salinity ranged between (1-1.8) mg/L in well 3, DO ranged between (2-8.2) mg/L in wells 2,3 respectively, total hardness ranged between (160-500) mg/L in wells 2,3 respectively, and calcium ranged between (100-180) mg /L in wells 1,2 and well3 respectively, and magnesium ranged between (40-340) mg /L in wells 2,3 respectively, while chloride and sulfates reached (53.25 - 88.75) mg /L in wells 1,3 and well3 respectively, and (843 -1955) mg /L in wells 1,3 respectively.
These results reflect the geological nature of the area in which the water passes, in addition to the effect of rainfall on water quality. Turbidity, dissolved oxygen, total hardness, calcium and magnesium did not permissible the standard standards, except for EC, TDS, salinity, Cl- and SO4-2. So, these wells water is acceptable for drinking except after treatment and suitable for animal consumption, but suitable for most domestic uses.
