Hydrogeologic Assessments

GLEC has over 20 years of experience in evaluating soil and groundwater quality impacts from a wide variety of industrial operations, including automotive, aircraft, electronics, chemical manufacture, fuel storage and refining, power plants, metal coating operations and unregulated and permitted landfills. Evaluations conducted under state and federal regulatory jurisdictions including facilities subject to RCRA Corrective Action and permit enforced groundwater monitoring programs. In addition to industrial operations, GLEC manages an ongoing groundwater monitoring and assessment program for a major U.S. Army munitions facility.

GLEC is experienced in the design and installation of monitoring well networks, aquifer testing, and compliance monitoring. Soil and groundwater quality assessments have been conducted to identify contamination sources, to delineate migration patterns of groundwater contamination and movement, and to develop remedial action alternatives for the removal of chemicals in soil and groundwater to compliance levels. In conjunction with these evaluations, we have prepared remedial alternatives analyses and cost comparisons, and directed cleanups to facilitate risk based closures of industrial and commercial sites.


GLEC operates one of only a few U.S. laboratories accredited for whole sediment toxicity testing.
GLEC also maintains NELAP accreditation for chlorophyll and nutrient chemistry testing.
