Abstract
This study takes place in year of 2021 during the premonsoon and postmonsoon seasons and twenty water samples were collected. Chemical factors like chloride, fluoride, sulphate, nitrate, and phosphate were measured in water samples. There is a significant difference in anion dominance between pre- and postmonsoonal (PRM and POM) water samples. The following anions are HC O 3 > TDS > C l − > S O 4 2 − > TH > N O 3 > F − > P O 4 and TDS > HC O 3 − > S O 4 2 − > C l − > TH > N O 3 − > F − > P O 4 − . In both seasons, particular way of cations is Na + > Ca 2 + > Mg 2 + > K + . SAR, Kelly's ratio, residual sodium carbonate, potential salinity, permeability index, and sodium percentage were used to evaluate the irrigation water quality. To investigate the geochemical regulation and hydrogeochemistry of groundwater, two approaches were used: according to the findings, groundwater in various parts of the investigation was determined to be unfit for human consumption.
