Investigating Groundwater Condition and Seawater Intrusion Status in Coastal Aquifer Systems of Eastern India

Providing sustainable water supply for domestic needs and irrigated agriculture is one of the most significant challenges current century. This challenge more daunting in coastal regions. Groundwater plays a pivotal role addressing this hence, it under growing stress several parts world. To address challenge, proper understanding groundwater characteristics an area essential. In study, spatio-temporal analyses pre-monsoon post-monsoon levels two aquifer systems (upper leaky confined underlying confined) were carried out Purba Medinipur District, West Bengal, India. Trend analysis seasonal aquifers was also performed using Mann-Kendall test, Linear Regression Innovative test. Finally, status seawater intrusion evaluated available groundwater-quality data Chloride (Cl−) Total Dissolved Solids (TDS). Considerable spatial temporal variability found aquifers. Further, decreasing trends spotted groundwater-level time series aquifers, except Contai-I Deshpran blocks, level Ramnagar-I block aquifer. The Contai-I, Contai-III, blocks Nandigram-I Nandigram-II are vulnerable to intrusion. There urgent need real-time monitoring quality both systems, which can ensure efficient management reserves.
