Data Management & Analysis

In accordance with the Denver Federal Center (DFC) Site-Wide RCRA Facility Investigation (RFI) Quality Assurance Project Plan and corresponding standard operating procedures, SSP&A provides field and QA/QC sampling, data validation, sample result screening, evaluation, and data management, and reporting at the DFC site.

SSP&A performed a detailed investigation that revealed contaminated soil remains at concentrations exceeding levels protective of residential/unrestricted use but are intertwined with subsurface utilities or in lenses that extend under buildings and roadways at the Denver Federal Center site.

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

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

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 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.
