|Abstract:||The present study was undertaken with an aim to understand the response of groundwater resources in Bist-Doab catchment of Punjab in Northwest India to sustained abstraction for irrigation and forecast likely future trajectories. The groundwater samples were taken randomly from 19 sites for deeper and shallow aquifers and the nitrate may have breakthrough from the shallow groundwater to depth which is likely to be enhanced in the future if the current increases in pumping from the shallow and deep aquifers continue. The naturally occurring contaminants arsenic and fluoride were present at concentrations below WHO guideline drinking water limits for all sites and median concentrations were below 10 μg/L and 1.5 mg/L, respectively. This has implications for future contamination of deep sources of drinking water from other anthropogenic contaminants such as pesticides.|
