Electromagnetic TEMcompany sTEM10
#102036
The sTEM system maps subsurface geological layers via the time-domain electromagnetic method, making it ideal for locating new groundwater wells and estimating the extent of aquifers and groundwater recharge potential.
The sTEM can also be used to locate large fractures in the bedrock and estimate the thickness of a weathered overburden. Mapping surface layers to identify the best sites for artificial infiltration of surface water into aquifers is another use of the sTEM.
The system is designed for ease of use and requires limited training for a field crew. All sTEM instruments are operated from an iOS or Android App, and data is processed on a Windows PC.
EXI offers the sTEM 10 amp system in two configurations for deployment:
- The classic in-loop configuration using a 40x40m single-turn transmitter wire as deployed here.
The sTEM 40m transmitter loop being deployed.
2. The 3x3m Profiler offset loops kit (shown below). The 40m loops will be used to image depths to 1600 feet while the Profiler is designed for more rapid mapping of the top 300 feet.
