Abstract: Abstract Groundwater is an essential natural resource that ensures people have access to safe drinking water, which is important for their health and well-being. The present study assessed the suitability of groundwater by using the Canadian Council of Ministers of the Environment Water Quality Index (CCMEWQI) and the Groundwater Water Quality Index (GWQI) model. The hydrogeochemical characterization in groundwater was elucidated by plotting the piper trilinear diagram of major cations (Ca2+, Na+, Mg2+, K+) and anions (HCO3−, Cl−, SO42−, F−). Performance evaluation of WQI models indicated that the CCMEWQI performed better than GWQI for assessing groundwater quality index with a comparatively higher R2 value of 0.97 and less NMSE, RMSE, and MAPE. Six heavy metals, viz. arsenic (As), iron (Fe), manganese (Mn), copper (Cu), lead (Pb), and nickel (Ni), were investigated in the groundwater from 65 locations in Ranchi city. Significant water-level fluctuation was observed (WLF—3.5–5.7 m) in the central and western parts of the study area. The non-carcinogenic and carcinogenic health risk of heavy metals hazardous quotient (HQ) was investigated and found that As (HQ > 1), followed by Mn > Pb > Ni > Fe > Cu (HQ 1).
