ARM's geophysicists have performed more than 1000 surveys at sites located across the country. These sites have been situated in varying terrains having many different types of subsurface conditions. Our geophysicists apply their geological and geotechnical backgrounds and experience to provide cost effective surveys for the following primary areas of geophysical investigation:
Geotechnical Surveys
During engineering and land development projects, ARM's geophysicists provide
enhanced data acquisition capabilities. We use non-destructive geophysical techniques
such as ground penetrating radar (GPR), microgravity, resistivity (electromagnetic
imaging), and seismic surveys to obtain subsurface information more quickly and
more cost effectively than using conventional methods of data acquisition.
Our areas of expertise include:
- Sinkhole investigations
- Top of rock surveys
- Bedrock rippability determinations
- Concrete inspections (Structure Scans)

Water Resource Surveys
We assist with the development of water resources by conducting non-intrusive and
relatively low-cost surveys that help hydrogeologists delineate potential sources
of water as well as particular types of water bearing materials such as sand and
gravel.
ARM's geophysicists have experience providing.
- Well Siting
- Support for fracture trace analyses
- Top of bedrock delineation
- Downhole geophysics for well construction and rehabilitation
Environmental Surveys
Prior to conducting intrusive subsurface investigations (drilling borings or digging
backhoe trenches) to identify contaminants or buried storage containers, ARM's geophysicists
conduct non-intrusive surveys to provide an indication of subsurface conditions.
Types of projects where geophysical surveys can aid in saving valuable time and
reduce costs include:
- Initial delineation of contaminant plumes
- Determination of migration pathways
- Location of buried drums/USTs
- Identification of the limits of subsurface fill or waste
Utility Location
ARM geophysicists have located underground utilities in multitudes of different
settings for many purposes. We have located single, relatively short conveyance
pipes as well as complex networks of water, sewer, condensate, electrical, and telephone
lines at a large industrial facility. Our services have included:
- Site-wide utility mapping
- Individual utility tracing
- Clearing for individual boring locations
Oil & Gas Applications
Geophysical well logging is routinely used in virtually every oil well drilled in
the world today. It is the primary means by which we characterize the subsurface
in search of hydrocarbons.
