ABSTRACT

The physico-chemical parameters of groundwater in the hard rock terrain largely depend upon geological setup of the area. However, anthropogenic activities adversely affected the quality of groundwater. Groundwater Quality Index (GWQI) was calculated by considering various physico-chemical parameters (pH, EC, TDS, Bicarbonate, Chloride, Fluoride, Nitrate, Sulfate, Calcium, Sodium, Magnesium, Iron, Zinc, and Manganese) of the groundwater samples, to assess overall quality of groundwater for drinking purposes. Groundwater with poor and very poor quality was observed in the sites contaminated by Fe2+, Mn2+, F- and Zn2+, as these ions were given more weightage due to their greater influence in water quality even in very low concentration. Inverse distance weighted (IDW) raster interpolation technique of Spatial Analyst Module was used to generate the spatial distribution maps of various groundwater quality parameters. Good to very good quality of groundwater (GWQI <50) was reported in approximately 33% of the study area while Poor to very poor quality of groundwater GWQI >75) was reported in around 35% of the study area, which needs immediate management.

Keywords: Groundwater Quality Index (GWQI), Ranchi, Physico-chemical parameters, Groundwater, Interpolation.
