use Vertical electrical sounding.

Hi, Groundwater is characterized by a certain number of parameters, which geophysical methods try to determine from surface measurement mostly indirectly, but sometimes directly. Groundwater is a primary input for the sustainable development of an area. It plays a protective role against the vagaries monsoon. The surface resistivity sounding is very much effective in estimating aquifer thickness and basement topography which help in identifying various suitable sites for groundwater exploration.
everywhere, Vertical Electrical Sounding is one of the very common geophysical methods used for domestic borewell exploration. However, sufficient open area around the location is needed for conducting the survey.

In some part of world the local divine people use the magnet and wooden plank and magnet for identification of well site, but I am sure this method is not useful with critical geographical conditions.
