Cape Cod Wastewater
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.
OTIS AFB MMR Fate-and-Transport Analysis, Modeling, and Remedy Design
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.
Bannister Federal Complex
Historical operations at the Bannister Federal Complex had led to extensive contamination with chlorinated solvents, PCBs, hexavalent chromium, and petroleum hydrocarbons.
