California is suffering from drought and lack of drinking water. That is the reason why the U.S. Geological Survey (USGS), in cooperation with the California Water Resources Control Board, has contracted SkyTEM to conduct an electromagnetic geophysical survey of the subsurface in Southern San Joaquin Valley. The purpose of the survey is to protect all waters and monitor the groundwater that has the potential to be a source of drinking water and to characterize and monitor risk zones.
The survey is scheduled to start end September.
