Assessment of hydro-geochemistry and groundwater quality of Rajshahi City in Bangladesh

The study was carried out to understand the hydro-geochemistry and ground water quality in the Rajshahi City of Bangladesh. A total of 240 groundwater samples were collected in 2 years, i.e., 2009 and 2010 covering the pre-monsoon, monsoon and post-monsoon seasons. Aquifer soil samples were collected from 30 locations during the monsoon in 2000. All the samples were analyzed for various physicochemical parameters according to standard methods of analysis, these includes pH, electrical conductivity, total dissolved solids, total hardness, and total alkalinity, major cations such as Na+, K+, Ca2+, Mg2+, and Fe2+, major anions such as HCO3 −, NO3 −, Cl−, and SO4 2− and heavy metals such as Mn, Zn, Cu, As, Cd and Pb. The results illustrated that…
