Groundwater contamination recently has come to the attention of the public as incidents of contamination are being reported from every state. Central Ground Water Board, Southern Region, for the last nearly five decades has been carrying out hydro geological and hydro chemical investigations and has generated voluminous data.

India is a vast country with varied hydrogeological situations resulting from diversified geological, climatological and topographic settings. Water-bearing rock formations (aquifers), range in age from Archaean to Recent.

Ground Water Year Book is prepared annually by CGWB depicting changes in groundwater regime of the country through different seasons. It is an effort to obtain information on groundwater levels through representative monitoring wells. The important attributes of groundwater regime monitoring are groundwater level.

The dynamic groundwater resources of India for the year 2023 are assessed following the Groundwater Estimation Methodology, 2015 (GEC–2015), which takes into account all the relevant parameters contributing to groundwater recharge and extraction.

The Union Minister of Jal Shakti, released the Dynamic Ground Water Resource Assessment Report for the entire country for the year 2023. The assessment was carried out jointly by Central Ground Water Board (CGWB) and States/UTs, which can be used for taking suitable interventions by various stake-holders.

Ground Water Year Book is the basic data report consisting information regarding the ground water regime, depth to water levels and quality and their variations in space and time compiled and analyzed based on the information generated through field studies.

Monitoring of ground water levels from 768 (745+23) Hydrograph Network Stations (HNS) were carried out in the year 2021-2022 with an objective to assess ground water regime of phreatic aquifer. The water level monitoring was carried out manually in the months of May’19, August’19, November’19, and January’20.

Central Ground Water Board, North Central Region, Bhopal monitors ground water level in the state of Madhya Pradesh through a network of 1482 ground water monitoring dug wells and piezometers, four times in a year in order to bring out the spatial and temporal changes in the ground water regime.
