- Gardena Marketplace Interim Removal Action Workplance
- DTSC, pursuant to Ch. 6.8, Division 20, Sections 25323.1 and 25356.1 has approved the Interim Removal Action Workplan (RAW) at the former Honeywell Gardena Facility property (now Gardena Marketplace), located in Gardena, CA, hereinafter "the Site or Site Area". The project plan, Interim Removal Action Workplan for Volatile Organic Compounds in Soil, Former Honeywell Gardena Site, 1733 West Artesia Blvd., Gardena, CA, CH2M, August 11, 2015" is incorporated by reference. The RAW proposes to remove volatile organic compounds (VOCs), primarily Tetrachlorethylene (PCE) and Trichloroethylene (TCE), contamination in soil gas from beneath and adjacent to occupied commercial and residential buildings using a soil vapor extraction (SVE) system. PCE and TCE are the two primary soil vapors COPCs for the Site, and although other VOCs were detected in soil vapor and groundwater at the Site, PCE and TCE have been detected at the highest frequency and concentrations, and other VOCs where detected are generally collocated with PCE and TCE with much lower concentrations.
