Sudbury Landfill RI/FS

Floyd|Snider has teamed with Schwyn Environmental to perform the Remedial Investigation/Feasibility Study (RI/FS) for the Sudbury Landfill under an Agreed Order with the Washington State Department of Ecology. The Sudbury Landfill is an active municipal landfill on the outskirts of Walla Walla, Washington that is operated by the City of Walla Walla. Several of the older cells of municipal waste may have contained hazardous chemicals, including solvents, that have reached the shallow water bearing zones that are used by downgradient residences as their water source. Field efforts will fully characterize groundwater and soil conditions at and downgradient of the landfill.
