Document Description
The DTSC is proposing to approve a Remedial Action Plan pursuant to authority granted under Chapter 6.8, Division 20, California, California Health & Safety Code (H&SC). The purpose of this RAP is to implement remedial activities at Site 24 that are protective of public health and safety and the environment. Chemicals of concern (COCs) in soil at Site 24 include perchloroethene, trichloroethene, cis-1, 2-dichloroethene and vinyl chloride. The RAP proposed remedial alternatives for soil gas and groundwater that include the following activities: soil excavation to 8 feet below ground surface and backfill; off-site disposal of excavated soil; in-situ treatment of groundwater with zero-valent iron and nutrients; and soil gas and groundwater monitoring. Implementation of the proposed remedial alternatives would: 1) ensure that the exposure pathways would be eliminated for future residents and occupational workers at Site 24; 2) prevent exposure to COCs in soil gas (that emanates from the groundwater) to future residents and occupational workers; and 3) reduce the potential for COCs in soil to migrate to groundwater.
