In recent news by Deccan Chronicle, National Geophysical Research Institute (NGRI) is planning to take up a massive a groundwater mapping programme across the entire landmass of India using advanced helicopter surveys.

Aquifer mapping will help prepare a 3D map of groundwater resources at every point across the country and hence help in their efficient usage and sustainability.

In collaboration with Aarhus University in Denmark, NGRI had taken up pilot projects in five states (Tamil Nadu, Rajasthan, Bihar, Uttar Pradesh and Maharashtra) of India for aquifer mapping two years ago.

Most countries in the world are now using continuous aquifer mapping to ascertain their groundwater resources and use them judiciously. These surveys can even find points and sources of contamination in groundwater.

The institute has put the proposal on the desk of Union Ministry of Water Resources and is waiting for a green signal. The mega project could span up to a decade and cost Rs 8,000 to Rs 10,000 crore.

Dr Shakeel Ahmed, chief scientist and team leader, Indo French Centre for Groundwater Research (IFCGR), NGRI, said the outcome of the pilot project was extremely satisfactory.
