Electromagnetic Profiling (EM) provides unique and valuable information about subsurface content, properties, and anomalies. American Geophysics Inc. can combine both EM and GPR to provide one of the most comprehensive geophysical investigations possible. Using the latest industry technology (GSSI EMP-400), (Geonics EM-31, Geonics EM 61), we can easily cover all types of job sites and environments ranging from square feet to acres. This unique system allows us to capture data over multiple frequencies simultaneously while logging GPS coordinates of the gathered information. After the scan, we post-process the data, providing high-quality, accurate figures, which can be vital in determining where to focus your efforts first. Electromagnetic Profiling is essential, and we’re the team of experts to trust to handle the job for you.
Why Use EM Services?
Comprehensive spectrum and colored data sets can overlay directly over aerial images.
Can measure conductivity and in-phase data simultaneously.
Can penetrate to depths as great as ~12 ft below grade.
Can cover larger areas of land, in a more timely manner.
Can detect metallic and non-metallic subsurface anomalies.
Can detect concrete structures in the subsurface.
Pairs with GPR for more extensive and focalized investigations.
American Geophysics conducted a comprehensive electromagnetic profiling investigation at a historic uranium processing site in New York City. The mission focused on identifying potential underground storage tanks (USTs) and other subsurface anomalies that could pose environmental or structural risks.
Our client needed an Electromagnetic Profile of their property to measure the conductivity, collect in-phase data, as well as determine the presence of any subsurface metallic anomalies consistent with underground storage tanks (USTs), for heating oil, as well as any associated piping.
Using GPR, and the RF equipment, we were able to identify radial cables coming from the base of an antenna and their pathways across the property and to the main building in Lodi, NJ.
An abandoned in place, decommissioned or “orphaned” underground storage tank was detected in the walkway to the home. The previous owners tried to “hide the vent line” by painting the vent line the same color as the wall, as well as, using similar piping for the railing of the staircase that matches the vent pipe.
One major thing that sets us aside from the other locating firms is that our methodology consists of three layers of investigation, whereas most firms only provide one. The other firms only use magnetometers, which solely detect magnetic/metallic presences in the subsurface.
