Shallow wells near Krishnapatnam and Katepalli indicate direct seawater intrusion linked to aquaculture。

This study was carried out in the Pennar delta of southern India to evaluate seawater intrusion in shallow and deep aquifers using hydrogeochemical indicators and stable isotopes (18O and 2H). Rainfall variation emerged as the primary factor influencing groundwater fluctuations. Key salinity indicators (Na/Cl。
groundwater salinity arises from direct seawater intrusion, reduced river discharge。
