Question raised in Lok Sabha on Groundwater Resources in India, 27/06/2019. Central Ground Water Board (CGWB) carries out ground water monitoring, four times a year, on regional scale through a network of observation wells in the Country. As per the pre-monsoon water level data (2018), the deeper ground water level (more than 40 meters below ground level) has been observed in the isolated pockets in some of the States/UTs. State-wise depth to water level and distribution of percentage of wells for the Period of Pre-monsoon, 2018 is given at Annexure I. In order to assess the declining/rising trend in water level on a long-term basis, pre-monsoon water level data 2018 has been compared with the decadal average (2008-2017) water level. Analysis of data indicates decline in ground water level in about 52% of the wells and rise in 48% wells being monitored. State-wise details are given at Annexure II.
