The Central Ground Water Authority of the Union Ministry of Water Resources, River Development and Ganga Rejuvenation on December 12, 2018 notified revised guidelines for ground water extraction. The revised guidelines, which will be effective from June 1, 2019, aim to ensure a more robust ground water regulatory mechanism in the country. The guidelines were revised in the wake of the directions issued by the National Green Tribunal (NGT) to address various shortcomings in the existing guidelines of ground water extraction.
