| 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. |
