CONTEXT:

• The National Green Tribunal has directed a committee to take groundwater samples and study the methodology of recharging it. The decision came after a plea alleged that rainwater harvesting structures built by the civic bodies were contaminating water.
• A bench headed by NGT Chairperson Justice Adarsh Kumar Goel asked the committee comprising representatives from the Central Pollution Control Board, Delhi Pollution Control Committee and the Central Ground Water Board to submit the report within a month.
• Delhi Pollution Control Committee will be the nodal agency for coordination and compliance of the order.
• NGT had earlier imposed a penalty of 5 lakh Rs. each on educational institutions in the National Capital for failing to install rainwater harvesting systems
