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. � 2020 Informa UK Limited, trading as Taylor & Francis Group.
