SRS is the prime contractor managing multiple, concurrent projects involving hazardous site investigations, soil gas and radiological surveys, monitoring well abandonments, and providing technical support for multiple National Priority List (NPL) sites at Crab Orchard National Wildlife Refuge (CONWR). Beginning with World War II, some parts of the Refuge were used for ordnance and other defense manufacturing activities that resulted in soil and groundwater contamination.

Technical support includes finalizing the groundwater risk assessment, reviewing and providing comments on the Draft FS report and reviewing and providing comments on the Final FS. Other activities currently underway include Proposed Plan review and providing comments; review of open house meeting plans and assisting with open house meetings; providing mediation support to USFWS; participating in meetings and teleconferences with USFWS managers and Potentially Responsible Parties (PRPs); and responding to and providing all correspondences for the project.
