Crown Kana Cleaners Feasibility Study - Removal Action Workplan

Crown Kana Cleaners Feasibility Study - Removal Action Workplan

The approximately overall 4.5-acre commercial Site is bordered by a concrete-lined drainage channel on the north and east, Warner Avenue on the south, and Springdale Street on the east in the City of Huntington Beach. The dry cleaner business operated from approximately 1971 until 2018. A Phase II Site Investigation in June 2018 found chlorinated solvents in soil vapor samples collected beneath and local to the former Crown-Kona Cleaners, suggesting a potential release of dry-cleaning chemicals to the subsurface. The maximum detected concentrations of cis-1,2-Dichloroethene, Tetrachloroethene (PCE), and Trichloroethene in soil vapor indicated a potential vapor intrusion concern. Additionally, chlorinated solvents have impacted groundwater. The SVE system does not directly address groundwater impacts but will decrease or eliminate an on-going threat to groundwater posed by VOCs in vadose zone soils. The dry cleaner suite is located approximately 250 feet north west of Tesoro Service Station No. 42052 (former ARCO Facility No. 3053), where remediation of hydrocarbon impacted soil and groundwater has been ongoing since at least 1993 at the Tesoro Site. DTSC and Kitsigianis Properties, LLC executed a Voluntary Cleanup Agreement (VCA), Docket Number HAS-FY 18/19- 029 to address contaminates the Crown-Kana Project Site. See NOE for full details.
