The National Green Tribunal (NGT), Southern Zone, Chennai, has initiated Original Application No. 43 of 2026 (SZ) concerning the contamination of groundwater with petrol in Kovilambakkam, Tamil Nadu, following a news report. The Tribunal has issued notices to the respondents, including the Chief Secretary to the Government of Tamil Nadu, and has directed the Tamil Nadu Pollution Control Board (TNPCB) to inspect the site, take samples, and file a comprehensive report with water analysis results.
