Subsurface UXO Survey

Geophysics

ARM's geophysicists have performed more than 500 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 five primary areas of geophysical investigation.

ARM's six primary survey areas are:

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 often 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 contaminate plumes
  • Determination of migration pathways
  • Location of buried drums/USTs
  • Identification of the limits of subsurface fill or waste

UXO/OE Mapping
Specific skills are required to identify ordnances in the subsurface. ARM's geophysicists have developed these skills and have considerable experience conducting geophysical surveys at ordnance sites across the United States. These capabilities include:

  • Successful performance of geophysical prove outs
  • Performance of meandering path surveys
  • Performance of re-acquisition survey
ARM has two key teaming partners with whom we conduct UXO/OE projects, Explosive Ordnance Technologies Incorporated (EOTI) and EOD Technologies, Inc (EODT). Please visit our partners' web sites at: www.eoti.net and www.eodt.com.

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

Borehole Geophysics
Borehole geophysical logs provide continuous and objective records that present valuable information about the physical properties of the soil and rock through which borings are drilled. Borehole logs also provide information about the fluids in those soils and rocks and about the construction of wells completed in those materials. ARM uses fully digital, state-of-the-art well logging and imaging systems that include the following tools for environmental, geotechnical, mining, and coalbed methane applications:
  • Optical Televiewer (OPTV)
  • Acoustic Televiewer (BHTV)
  • Natural Gamma
  • Spontaneous Potential
  • Three-Arm Caliper
  • Resistivity/Conductivity
  • Fluid Conductivity
  • Fluid Temperature
  • Gamma-Gamma Density
  • Neutron
  • Single Point Resistance
  • Heat Pulse Flowmeter
  • Borehole Video
