Heavy metal concentration in groundwater and soil samples from around NLC India Limited are within permissible limits, says the Tamil Nadu Pollution Control Board (TNPCB) in a report submitted at the National Green Tribunal (NGT).
In a suo motu case taken up by the southern bench of the NGT in August 2023 based on news reports about a report on pollution due to effluents from thermal plants in Neyveli, the TNPCB was directed to file a comparative test report.
As per the report titled ‘POWERing Pollution’, published by non-governmental organisations Poovulagin Nanbargal and Manthan Adhyayan Kendra in August 2023, high levels of mercury, selenium, and fluoride were found in drinking water from as many as 20 locations around NLC India Limited.
