Airborne Electromagnetic (AEM) Survey 2022
Active
By Upper Midwest Water Science Center
January 26, 2022
The U.S. Geological Survey (USGS) is conducting an Airborne Electromagnetic (AEM) Survey project in Southwestern and Southeastern Wisconsin.
The survey is in partnership with Wisconsin Geological and Natural History Survey (WGNHS), Natural Resources Conservation Service (NRCS) and Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP).
What is the survey for?
Sources/Usage: Public Domain. View Media Details
The survey will use airborne electromagnetic (AEM) technology to better understand how surface water and groundwater are connected, and the geometry of different aquifer units. To accomplish this, AEM data will be collected to image surficial confining units, shallow aquifers, and bedrock units. The use of a helicopter-towed AEM sensor (looks like a large hoop hanging from a cable) for this type of evaluation uses cutting-edge technology and provides accurate science-based data about below-ground properties that are otherwise difficult to assess over large areas. This project is in response to public feedback on groundwater quality, limited data on depth to bedrock, and to further define aquifer properties in relation to surface activities.
When and where will it happen?
Flights are expected to start in late February/early March 2022 and exact dates will be weather dependent. At this time, surveying will take place in the following counties: Grant, Iowa, Lafayette, Green, Waukesha, Walworth, Racine, and Kenosha.
Why is measuring subsurface geology important for water quality?
Sources/Usage: Public Domain. View Media Details
Much of Wisconsin’s drinking water comes from groundwater and groundwater sources. Degradation of groundwater quality has been a rising concern as well as the influence of groundwater connections to our streams. Having a better understanding of aquifer properties as well as connectivity to the surface (depth to bedrock), allows practical guidance for the development of approaches to maintain a healthy groundwater system. Using AEM allows scientists to develop a 3D image of the subsurface geology to better predict how water moves through those layers and how groundwater and surface water are connected.
How does this benefit the public?
This survey supports public health efforts to help protect groundwater and promote water quality. The results of the survey will:
-
Create a better understanding of aquifer properties
-
Address groundwater quality
-
Improves understanding of the influence of surface activities (agriculture, mining, development, etc.) on groundwater quality
This project uses the strength of local, state, and federal resources to help many citizens in southern Wisconsin.
Helicopter Activity: What to Expect

Sources/Usage: Public Domain. View Media Details
- Flights are expected to take 14-21 days depending on weather and flight conditions
- The helicopter is flying a grid pre-determined flight track based on study locations, so it will be seen several times in the same area
- The helicopter will fly relatively low, hundreds of feet above ground
- The helicopter will not fly within 500 ft of buildings according to Federal Aviation Administration (FAA) rules, and will make efforts to fly around people or large equipment on the ground
- The electromagnetic device will not harm plants, animals, or humans
- The low flying helicopter may startle wildlife and cattle and the helicopter will make efforts to fly around confined animal areas
- Local enforcement and conservation contacts are informed of the activity
- A flight tracker will map the daily progress of the study
- Only depth to bedrock and hydrogeologic properties will be identified through this process
