Read this CSE critique on NEERI report on assessment & remediation of hazardous waste contaminated areas in & around M/S Union Carbide in Bhopal. It says that NEERI has underestimated the extent of potential groundwater contamination & that there is a need for extensive research on aquifer movements in & around the UCC/UCIL factory, so that the extent of contamination can be ascertained and the need for draining aquifers for remediation can be known.
