Combining Two Thermal Technologies at the Groveland Wells Superfund Site
Contaminants of Concern (COCs): TCE; 1,1-dichloroethene; trans-1,2 dichloroethene; cis-1,2-dichloroethene; methylene chloride; tetrachloroethene; 1,1,1-trichloroethane; toluene; vinyl chloride.
- Shallow overburden (fill and dark brown loamy sand) layer extending from the ground surface to approximately 4 to 8 ft (1.2 to 2.4 m) below ground surface (bgs). The shallow overburden has a thin layer of perched groundwater in the sand layer just above the clay.
- Clay layer approximately 2 to 10 ft (0.6 to 3 m) thick, thinning north to south. The clay layer is approximately 8 to 16 ft (2.4 to 4.9 m) bgs with a downward hydraulic gradient
- Deep overburden composed of silty fine sand and/or glacial till extending to bedrock.
- Varying bedrock surface at approximately 45 ft (14 m) bgs.
