PROVIDING PROFESSIONAL GEOPHYSICAL SURVEYS TO MEET A WIDE RANGE OF CLIENT NEEDS

FORREST ENVIRONMENTAL SERVICES, Inc. (FES, Inc.) specializes in the conduct of geophysical surveys to provide clients with critical subsurface data collected through non-invasive, non-destructive methods.  FES Inc. has conducted hundreds of successful geophysical surveys providing clients with the data needed to make sound decisions.  

The application of geophysical methods is a cost effective means of obtaining substantial subsurface data along continuous lines and areas that cannot be obtained through traditional methods of borings and trenching.

CLIENTS

Our clients include the following:

bulletEnvironmental Engineers/Consultants
bulletLand Developers
bulletGeotechnical Consultants
bulletMining Companies
bulletFederal, State, and County Agencies
bulletIndustry
bulletIndividual Land Owners

APPLICATIONS

Geophysical surveys can provide critical information on subsurface conditions and are frequently conducted for  hydrogeological and geological investigation, environmental assessment, mineral exploration, geotechnical investigations, and anthropological assessments.  Some common applications are outlined below.  Specific FES survey examples and project summaries are provided within each application grouping (click to see examples and project summaries):

Anthropology

bulletSubsurface delineation of suspected anthropological sites

Environmental

bulletElectrical Resistance Tomography (ERT) monitoring of subsurface thermal remediation processes
bulletLocate buried materials such as drums, tanks, pipes, and utilities
bulletDelineate landfills, buried trenches and other subsurface anomalies 
bulletDetermine the presence of contaminant plumes, their distribution, direction, and rate of movement

Geotechnincal

bulletLocate leaks in dams and lagoons
bulletCharacterize stratigraphy, determine depth to bedrock
bulletLocate subsurface caverns or voids that can develop into sinkholes
bulletDetermine slope stability, identify saturated zones and delineate clay layers

Mining

bulletLocate mineral deposits

Water Resources

bulletLocate water-bearing fractures and zones of groundwater flow for monitor, remediation, and potable well installation 

 

METHODS

FES provides the following geophysical survey methods (click to see more information on each method):

bulletElectric Resistivity (ER)
bulletElectromagnetic Induction (EM)
bulletGround Penetrating Radar (GPR)
bullet Very Low Frequencies (VLF)
bullet Seismic Refraction
bulletGravity
bulletMagnetic
bulletMagnetotelluric (MT)

The use of such methods in a site investigation, where subsurface conditions are unknown or questionable, can lead to significant short term and long term cost savings.

FES can bid surveys at costs well below other geophysical specialty firms.  Our strong hydrogeological and environmental consulting background and experience enables us to select appropriate survey applications for a given set of site conditions.  Our ultimate goal is to provide our clients with a high quality and timely product while maintaining cost effectiveness.

To receive a bid or for more information concerning geophysical methods or if you have questions regarding your specific needs and site concerns, please contact us.
