Evaluation of the water quality of some wells in the village of Shamit - Zab district

Abstract

The current study included a field survey of the groundwater characteristics in the Zab district, where the bacteriological aspect of this water was examined to determine its quality. The study began in October 2024 and continued until March 2025, where six wells were selected in the area to collect water samples and analyze some of their characteristics. The results of the study showed that the air temperature in the studied area varied significantly between (15°C and 38°C) during October and March, while the temperature of water samples ranged between (19°C and 28.5°C). The pH values ranged between (7.0 and 8.74), the dissolved oxygen values ranged between (7.6 and 36.3) mg/L, while the biological oxygen demand (BOD) values ranged between (3.2 and 13.2) mg/L. Turbidity values in well water ranged between 0.00 and 20.97 NTU, while electrical conductivity values ranged between 1.859 and 3999 microsiemens/cm. Total hardness values in water ranged between 0.105 and 0.79 mg/L. Total dissolved solids (TDS) values ranged between 1.012 and 2000. Phosphate values ranged between 0.226 and 0.549 mg/L, while nitrite values ranged between 0.156 and 0.293 µg/L.
