Information from the remedial investigation activities do not indicate that there is any risk to indoor or outside air in offsite properties from benzene in groundwater originating from the former Philadelphia Refinery. Evaluation of vapors to indoor and outdoor air from a dissolved plume beneath the subsurface is part of the evaluation required by Act 2. That evaluation will be included in future Act 2 reports to be submitted upon completion of all Remedial Investigation Reports. Please note that the slide being referenced shows refinery data as well as data collected from other nearby Act 2 sites. Plumes originating from other Act 2 sites are evaluated by the appropriate responsible parties who are remediating those Sites.
