News release: Understanding the underground – DWR completes first phase of innovative groundwater mapping program
National Groundwater Awareness Week is next week, and in the spirit of promoting groundwater knowledge, the Department of Water Resources (DWR) is excited to announce that its innovative groundwater mapping project is complete and will provide critical information about our underground water supply. The Statewide Airborne Electromagnetic (AEM) Survey Project has now completed surveys in all high-and-medium-priority groundwater basins in California. AEM surveys use state-of-the-art helicopter-based technology to scan the earth’s subsurface to depths of up to 1,000 feet, like taking an MRI of the earth, to visualize the aquifer structures beneath our feet. You can see the AEM equipment in action in this DWR video: DWR’s Airborne Electromagnetic (AEM) Surveys: The AEM Method (youtube.com).
