Abstract

The freshwater resource crisis and human health risk due to drinking of contaminated water are the major issues in mining regions. The primary goal of the present study was to assess the major and trace elements concentration in the groundwater of North Karanpura Coalfield (NKC) of Damodar Valley to identify the major governing factors of groundwater chemistry and estimate the possible human health risk via the drinking water pathway. To achieve the objectives, 34 groundwater samples were collected in the NKC, and analysed for pH, electrical conductivity (EC), turbidity, total dissolved solids (TDS), total hardness (TH), major ions and dissolved metals. The results of the present study revealed that TDS, F−, NO3−, TH, Turbidity, Fe, and Mn were the major concerns and exceeded the Bureau of Indian Standards (BIS 2012) acceptable drinking water limits at many locations in the NKC area. The estimated WQI suggests that few locations were not appropriate for drinking uses. Moreover, the calculated heavy metal pollution index (HPI) indicates that 41% of the water samples belong to the medium class. Further, the calculated hazard index (HI) suggest that the child population were at a higher potential health risk than the adult population in the NKC area. The used approaches show that the quality of groundwater in the area was primarily controlled by the dissolution of minerals and weathering of rocks with minor contributions from agriculture, coal mining and other mining-related activities.
