CERCLA Compliance

SSP&A led site characterization, removal of contaminated soil, and stabilization and containment of remaining impacted soil to enable site redevelopment.

SSP&A was initially retained to provide expert review and evaluation of hydrologic, hydrogeologic, and geochemical conditions at the former Leviathan Mine Site, and to assess the sources of impacts of mining-related residues on groundwater and surface water.

Multiple Sites in EPA Region 5: Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin

The USDOE Hanford Site transitioned over decades from a Manhattan Project mission to environmental assessment and cleanup. SSP&A was initially engaged to assess groundwater conditions and develop and apply models to design, evaluate, and optimize groundwater remedies for CERCLA operable units across the Hanford Site.
