Hockessin Groundwater Removal Action


The selected response action in the 2019 Action Memorandum is intended to address the source area under and directly adjacent to the Sunrise Cleaners and effectively prevent any further tetrachloroethylene (PCE) contamination from this source area into the groundwater and the Site. The response action consists of heating the soils to approximately 215°F. PCE and other volatile organic compounds (VOCs) will then be volatilized and removed safely with vapor extraction.
