mainly gains water from groundwater which is continuously protected by various human activity even with
reckless deterioration. The maximum nitrate concentration reached up to 51 ppm whereas the amount of
phosphate found to be as 3.8 ppm. The average EC for a year is 38.1 mS/cm and corresponding salinity and TDS
found to be as 20.2 and 24.3 g/L respectively. The middle region of the territory consists less saline water and
0.132 ppm of Pb and 0.092 ppm Cd presence in the groundwater. The BTEX has been completely eradicated by
