Chemours Oakley Site Sediment, Soil and Groundwater Corrective Measure Studies

Chemours Oakley Site Sediment, Soil and Groundwater Corrective Measure Studies

DTSC is considering approval of three Corrective Measures Studies to address the release of Constituents of Concern. The proposed remedial activities would address the releases of COCs in sediment, soil, and groundwater that may pose a risk to human health or the environment. Key constituents of concern that will be remediated include lead, organolead, carbon tetrachloride, CFC-11, CFC-113, 1,2-DCA, tetrachloroethylene, and arsenic. Once these remedies are in place, it is expected that most of the upland area of the site would be redeveloped for industrial and commercial use, although a portion of the upland adjacent to wetland area may be used for recreational use. (e.g. walking trail).
