Abstract

The present investigation is aimed at understanding the hydrogeochemical parameters and development of a water quality index (WQI) to assess groundwater quality of a rural tract in the northwest of Bardhaman district of West Bengal, India. Groundwater occurs at shallow depths with the maximum flow moving southeast during pre-monsoon season and south in post-monsoon period. The physicochemical analysis of groundwater samples shows the major ions in the order of HCO3>Ca>Na>Mg>Cl>SO4 and HCO3>Ca>Mg>Na>Cl>SO4 in pre- and post-monsoon periods, respectively. The groundwater quality is safe for drinking, barring the elevated iron content in certain areas. Based on WQI values, groundwater falls into one of three categories: excellent water, good water, and poor water. The high value of WQI is because of elevated concentration of iron and chloride. The majority of the area is occupied by good water in pre-monsoon and poor water in post-monsoon period.
