Abstract: The present investigation is focused on seasonal variation and spatial distribution of the groundwater pollutants in the study area during post monsoon (January), summer (May), pre monsoon (August) and monsoon seasons (November). Geologically, the study area comprises quaternary alluvium made up clay, silt and sandstone deposits. Water quality parameters (WQPs) such as pH, EC, TDS, TA, total hardness, chloride, sulphate, bicarbonate, carbonate, calcium, magnesium, sodium, potassium, nitrate were chosen. GIS technique was used to find out the spatial distribution of the soluble pollutants. The WQPs were compared with the standard guidelines values as recommended by the WHO for drinking and public health. The abundance of major ions groundwater was found in the following order: Na+ > Ca2+ > Mg2+ > K+ and Cl− > HCO −3 > NO −3 > SO 24
Keywords: groundwater; seasonal variation; GIS; correlation; linear regression; east coast; India.
