Question raised in Lok Sabha on Depleting Ground Water, 18/07/2019. The Dynamic Ground Water Resources of the country are being periodically assessed jointly by Central Ground Water Board (CGWB) and State Governments. As per the 2017 assessment, Total Annual Ground Water Recharge is 432 Billion Cubic Meter (BCM) and the Annual Extractable Ground Water Resource is 393 BCM. The Annual Ground Water Extraction for all uses is 249 BCM. The Stage of Ground Water Extraction, which is a measure of Annual Ground Water Extraction for all uses (irrigation, industrial and domestic uses) over Annual Extractable Ground Water Resource is 63% for the country as a whole. Out of the total 6881 assessment units (Block/ Taluks/ Mandals/ watersheds/ Firkas) in the country, 1186 units in 17 States/UTs have been categorized as ‘Over-exploited’ where Annual Ground Water Extraction is more than Annual Extractable Ground Water Resource. State-wise details are given at Annexure.
