Electrical water detection in semi-arid hard rock areas

ScienceDaily (June 22, 2011)

A quick and easy way to detect groundwater in semi-arid hard rock areas that is also economical could improve the siting of borewells to improve clean water supply in the developing world. Details of the approach are outlined in the International Journal of Hydrology Science and Technology (June 2011)

P.D. Sreedevi, Dewashish Kumar and Shakeel Ahmed National Geophysical Research Institute in Hyderabad, India, explain how electrical conductivity (EC) logs of hard rock terrain recorded before and after the monsoon season can reveal differences that show where water accumulates most in subterranean rock fissures. By comparing the data with other geological measurements and drilling experiments, the team is available to correlate the EC data with regions of underground water without additional test drilling.
