Field Services

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 works with the Mississippi Department of Environmental Quality and the Federal Energy Regulatory Commission to manage monitoring oversight and long-term management of the Transco-Williams facility.

SSP&A was retained to identify the source of a 1,1,1-trichloroethane, 1,1-dichloroethene, and 1,4-dioxane plume in groundwater beneath the client’s facility was from the facility or from offsite source(s).

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

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

In support of litigation, SSP&A evaluated the impacts to groundwater and surface water from a wastewater treatment system and septic leach field at a commercial complex in Harwich, Massachusetts.

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 retained by the U.S. Environmental Protection Agency (EPA) Region 5 to evaluate groundwater conditions at the site and to collect environmental media to support the microcosm studies.

The State of Minnesota selected SSP&A to provide expert services for a natural resources damage lawsuit related to impacts to groundwater and surface water from releases of PFAS from the 3M manufacturing facility in Cottage Grove, MN.

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.
