Remedial Investigation

We regularly conduct Remedial Investigations at properties contaminated with myriad hazardous substances. The results lead to concise risk assessments, remedial alternatives analysis, cleanup, and contaminated site closure.

Our team has successfully completed Remedial Investigations at numerous commercial, industrial, Brownfield, and agricultural properties to characterize the extent and magnitude of contamination to various media. These include impacts to soil, groundwater, surface water, soil gas, sediments, and air quality.

The Remedial Investigation process for each property or facility is the foundation by which we assess human health or ecological risk, develop appropriate remediation goals, and conduct feasibility studies of viable remedial alternatives to achieve site cleanup goals and obtain regulatory closure. Our experts tailor the scope of each Remedial Investigation to the history of the property or facility use, known or potential release mechanisms, and the media of concern to meet our clients’ business goals as well as federal and state regulatory requirements.
