Waste Management

The Hyde Park Landfill is a hazardous waste landfill where approximately 20,000 tons of chlorinated compounds (primarily DNAPLs) were disposed in a fractured rock setting.

SSP&A developed analyses to predict the evolution of the concentration of chloride at a compliance boundary downgradient from an existing landfill and proposed new landfill cells.

SSP&A was retained to estimate and depict the lateral extent and the volume of radiologically-impacted material (RIM) within Areas 1 and 2 of Operable Unit 1 (OU-1) at West Lake Landfill Site

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.

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.
