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.
