Ground water, nutrient salts, physical and chemical properties


  The current study was conducted on 7 wells selected in the district of Al-Zubayr from Umm Anij farms to show some physical and chemical properties and the concentrations of nutritious salts of nitrate, nitrite, phosphates and silica in ground water. The results obtained for groundwater temperatures were almost equal between wells, with rates ranging between 22- 24 Cͦ. For chloride ion, the highest rate was in well (W7), reaching to 6812 mg / l , and the lowest rate in well (W5), which was 2599 mg / l. As for electrical conductivity, the highest rate was found in the well (W7 )reached to  8.540 mS/ cm ,and the lowest rate in well( W5) was 4.933 mS / cm ,the highest rate of total dissolved solids was recorded in the well (W7 )8976 mg / l and the lowest rate in the well( W5) 3923 mg / l  the results showed that the highest rate of pH reached to  8.78 in (W7) well, and the lowest rate was 7.21 in well (W5), As for the turbidity, the highest rate reached to  8.790 NTU in well( W7), and the lowest was 2.303 NTU in well (W5)  proportion to the values ​​of nutrients, the nitrite values ​​ranged as the highest value was 0.932 μg / l in well (W3 ),and the lowest value was 0.094 μg / l in well (W1), and the highest concentration of nitrate reached to 28.299 μg / l in well (W3 ),and the lowest value reached to  4.959 μg / l in well (W1). As for phosphates, the highest value reached to 1.089 μg / l for well (W3) and the lowest value was 0.879 μg / l for well (W2), and the resuits  showed that the highest value of silica reached to value 72.254 μg / l in well (W3), while the lowest value was 55.700 μg / l. Well (W1) during the study period. Well water was within the permissible limits for drinking and irrigation in proportion to nitrate and nitrite values, and the concentrations of chloride ions, electrical conductivity and total dissolved solids in the study wells did not match the standard specifications of drinking and irrigation water.
