Abstract:
The groundwater samples from different aquifers (shallow, intermediate and deep) were collected from
Jalandhar and Kapurthala districts, Punjab and analysed for major ions, stable isotopes of oxygen and hydrogen and
environmental tritium activity. The groundwater in shallow and intermediate aquifer is Ca-Mg-HCO3 and in deep
aquifer is Na-HCO3 hydro geochemical facies. The groundwater chemistry in the study area is influenced by silicate
dissolution of host rock. The shallow aquifer shows recharge is mainly through local precipitation. Location around
R. Beas show significant contribution from the river. The Bist- Doab canal shows very less contribution to shallow
aquifer. The enriched nature of isotopic composition in the shallow aquifer is mainly due to evaporation of water
during filtration through impermeable clayey layer. The groundwater in deep aquifer gets recharged mainly from the
precipitation from outside the study area.
