Fate and Transport Modeling

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.

For over 10 years SSP&A consulted to the NYSDEC spills department, evaluating and simulating the fate and remediation of fuel spills at multiple sites.

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

SSP&A was retained to develop a groundwater transport model that would explicitly account for the long-term fate of arsenic and boron in aquifers underlying the Coronet Industries Alternative Site, located in Plant City, Florida.

SSP&A was retained by Sparton Technology, Inc., to assist in the development of a remedial plan, litigation support, and negotiations with federal, state, county and city regulatory authorities for its Former Coors Road facility in Albuquerque, New Mexico.

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.

SSP&A was initially retained to evaluate the fate and transport of CrVI (from historical plating activities) and the effectiveness of a combined strategy of in-situ and ex-situ remedies.

SSP&A developed and applied a 3D groundwater flow and contaminant transport model for the OTIS/MMR as part of remediation efforts at the site, and was subsequently retained to undertake wide-ranging data analysis, reporting, and remedy evaluation and optimization tasks.

Historical operations at the Bannister Federal Complex had led to extensive contamination with chlorinated solvents, PCBs, hexavalent chromium, and petroleum hydrocarbons.

SSP&A was retained to evaluate the locations, timing, and quantities of historical contaminant discharges to the Columbia River to support a potential Natural Resource Damage Assessment (NRDA) claim.
