Analysis and Control of Saline Water Intrusion into a Coastal Aquifer in West Bengal, India (original) (raw)

Saline water intrusion into fresh groundwater aquifers takes place in the vicinity of coastal regions having hydraulic continuity with sea. India has significantly long coastal belt and contamination in the aquifers in these regions by saltwater intrusion has been evidenced. Such intrusion is likely to cause serious consequence if such aquifers are tapped for domestic water supply, irrigation or any other specific purpose. This paper is based on extensive field study on subsurface and groundwater characterization in a coastal city of West Bengal, India. An innovative methodology was developed to control the saltwater intrusion into coastal aquifers.
