    • Abstract

       

      Temporal variations have been observed in both dissolved helium and TDS in the form of increase in basaltic and decrease in alluvial aquifers. The increase in basaltic aquifers has been explained by enhanced pumping of old groundwater with relatively higher concentration of dissolved helium and salt, whereas the decrease in alluvial aquifers has been explained by dilution from the post monsoon groundwater recharge. Therefore, the observed temporal variations cannot be ascribed to the contemporary enhanced seismic activity in this region since August–September 2000.
