We are using the latest airborne electromagnetic survey technology, helicopter time-domain electromagnetics (HTEM), to see deep into the subsurface and get a picture of our aquifers that we have never had before. You may see a helicopter towing a large hoop hanging from a cable, which is a device that uses electromagnetics to create images of the subsurface. The information we collect from this process will help us to create a 3D picture of what the aquifers look like as deep as 1,000 ft (300 m) underground.
