Geophysics

EDI provides geophysical surveying services that include ground-penetrating radar, electromagnetic induction, electrical resistivity, magnetics, seismic refraction, gravity and VLF surveys throughout the United States. 

EDI performs geophysical surveys that accomplish several objectives that include 1) determining depth to bedrock (electrical and seismic methods), 2) establishing IBC Site Class via Refraction Microtremor - ReMi (seismic method), 3) locating buried metallic debris and drums (magnetic method), 4) delineating boundaries of solid waste management units - SWMUs (electromagnetic method), and 5) locating buried utilities, piping, and tanks (ground penetrating radar - GPR method)).

EDI performs geological site assessments (aka Geological Hazard Surveys) of properties (and surrounding land), to address county growth management concerns.

Other services include:

Seismic Site Classifications (NEHRP / IBC / Vs30)

Soil properties (P-wave and Shear-wave velocities)

Measuring depth to bedrock

Groundwater investigations (Hydrogeophysics)

Landfill mapping (boundary delineations)

Locating buried waste, drums and underground storage tanks

Locating unexploded ordnance (UXO)

Locating abandoned wells

Utility locating

Rebar mapping

Rippability

Soil resistivity
