Physical and Chemical Properties Study on the Groundwater in Tuz District

The present study is carried out to detect some quality properties of groundwater at Tuz,. The results showed that air temperature noted minimum at ranged between (8-35)C° , and The recorded temperatures of ground water values range between (18-25)C°, Turbidity values for all wells water at the study area ranged (0.00-29.88)NTU, It is obtained that wells near-off the mountain chain Nafed dag increase of electric conductivity comparative ranged between (734-6890)μs/cm. Groundwater in the study area was Brackish dependence to the total dissolved salts ranged (20-5860)mg/l . The pH values ranging between (4.15- 8.91) . It was noted that the values of the dissolved oxygen are few and almost non-existent in some cases it ranged between (0.8 -0.30)mg/l. Analysis of biological oxygen demand refers to wells water (very clean) levels involving (0.00 -0.15)mg/l. Reason of groundwater very hardness ranging values of total hardness , calcium and magnesium hardness between (300-2440) mg/l , (160-1400)mg/l and (44-1580)mg/l respectively. The total alkalinity ranged between (74-600)mg/l , The chloride ions in ground water of the studied within the permissible limits for watering of animals and irrigation of plants, with values range (0.00-349.89)mg/l . Sulphates range between (134.5-3326)mg/l .Sodium values for all wells water at the study area ranged (112.35 -495.59)mg/l. Potassium values for all wells water at the study area ranged (1.158-51.036)mg/l. As for plant nutrients , ranged between the values of silica (9.688-25.981)mg/l.The concentration of active nitrite ions ranged between (0.000 –1.212) μg NO-NO2/L .As the values of phosphate , ranged between (0.26- 0.399) μg P-PO4/L during the study period.
