Geochemical Study and Remedial Measures of Seawater Ingression in the Southern Part of Purba Medinipur District in West Bengal
Subscribe/Renew Journal
There is a severe warning of groundwater pollution in the coastal district of Purba Medinipur, West Bengal. This is due to ingression of saline water intrusion. A top stratum of the soil in coastal area of the district is found to be made of different layer of clay and sand of sea origin. The groundwater cannot be used for domestic, irrigation or industrial purposes. As a result of continuous extraction of water, the groundwater is formed like a cone of depression. It has resulted in redundant well and therefore the water extraction has become uneconomical due to augmented lift. All these necessitate for urgent measures to control the ingression of salt water into the coastal aquifers. Some measures to control the encroachment of salt water are suggested in this paper.
