The efforts of CGWB were appreciated which resulted in mitigating water crisis in the area.

Based on Aquifer Mapping the Government of Tamil Nadu initiated regulatory measures for groundwater abstraction in the coastal areas of Cuddalore district in order to prevent sea water intrusion and protection of coastal aquifers.
