ECOLOGICAL ENVIRONMENT: A NEW PERSPECTIVE

In coastal aquifers, saltwater intrusion may cause serious consequences in terms of both environmental and economic impacts. An attempt has been made in the present study to elucidate the quality of groundwaterin the study area in terms of the chemical parameter change due to the seasonal variation of water level. The present study deals with the physio-chemical characteristics of groundwater quality in Nagapattinam district.The study area showed generally similar hydrochemical characteristics slightly higher level of Cl-, Na+, and EC was observed. Based on the Cl- , Na+ and EC data, the groundwater falls within high salinity.
