Abstract
The present study investigates the groundwater suitability for drinking and irrigation purposes in the Shivalik region of Punjab, India. The results revealed that the concentration of Se, U, and F− exceeded BIS acceptable drinking water standards in 18%, 9%, and 16% samples, respectively. Multivariate analyses indicate the geogenic origin for As, U, Fe, F− and SO42−, and anthropogenic for NO3−, Cu, and Cr. The carcinogenic risk of drinking water is in very low (10−6) to low (10−5) category, while cumulative non-carcinogenic risk (HI-1.2) is slightly higher than USEPA limits (HI-1). The groundwater quality was found suitable for irrigation purpose.
