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.

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).

SSP&A has performed a wide variety of investigation and remediation activities at the Denver Federal Center (DFC) for U.S. General Services Administration (GSA) and other construction contractors working at the site in Colorado.

SSP&A provided expert services for the State of New Mexico, New Mexico Environment Department (NMED), and members of the Navajo Nation in lawsuits related to a mine blowout at the Gold King Mine in Silverton, Colorado.
