NGRI Study Uses Electricity to Detect Water

Electricity can be used to detect groundwater in semi-arid hard rock areas, thereby improving water supply globally, according to a new research conducted by India-based research institute National Geophysical Research Institute (NGRI).

NGRI’s cost-effective approach uses electrical conductivity logs to compare data of hard rock terrain before and after the monsoon season in order to understand how water accumulates in subterranean rock fissures.

Drilling test boreholes or investigating underground openings will enable the understanding of hard rock aquifers and help find abundant sources of groundwater.

The NGRI research team based the findings on a study conducted in Maheshwaram in the Indian state of Andhra Pradesh.
