When clean-up will the community be notified in south and southwest Philly?

Evergreen is in the process of finishing the investigation activities at the former Philadelphia Refinery to identify the extent of the chemicals in soil and groundwater, in order to ultimately develop remediation (cleanup) plans for the site. During this process, Evergreen will develop reports and hold public meetings, both of which will have public notices. Throughout the process, we will post information to the... read more

These are very informative graphics (referring to the August 27th Public Information Session). What about removal of contaminants that are in the soil? Lead cannot be pumped out. All the soil must be removed.

Contamination in soil can be dealt with in many ways.  Some areas of soil impact have been excavated previously.  Soil remediation can also include institutional and engineering controls which eliminate a risk by blocking a pathway of exposure.  Remedial plans for all media will be detailed in the Cleanup... read more

Hilco has indicated in the Soil Management Report it filed with the City that the site-specific standard for lead required for the HRP intended uses for the site is 1,000 PPM. Will Evergreen remediate to this 1,000 PPM standard rather than the 2,240 PPM previously approved by PADEP?

Evergreen’s future cleanup plans will still compare all new soil data to both the statewide health and site-specific values to determine appropriate remedy selection.  In addition, Evergreen will reevaluate the current site-specific standard based on DEP’s proposed new soil standards and associated input... read more

These graphics (Evergreen note: assumption is reference to graphics from the August 27th Public Information Session relating to remediation) all show problems relating to gasses and water…not contaminated soil. Will soil be removed and replaced with clean soil?

The remediation systems operated at the site historically and currently were installed to address groundwater or vapors since those represented potential risk pathways, which is why they were shown during the August 27th Public Information Session. The purpose of the information session was to review historic reports which include mostly Remedial Investigation Reports.  Remedial plans for all media, including soil,... read more

What specific steps are being taken to clean the water from potential contaminants?

Since the original Consent Order & Agreement between Sunoco and DEP in 1993, Sunoco and Evergreen have implemented several interim remedial actions at the refinery. Various remediation systems were installed in the facility in 1995 to prevent the migration of impacted groundwater offsite. Additional remediation systems have been installed since that time to either address source removal (removing petroleum... read more

Have you considered remediating with bacteria? Or mycelium? We understand they’re both more affordable options.

Evergreen has considered and will continue to consider various remedial options at each area of proposed remediation. Remedial options must consider a number of factors, including but not limited to logistics, utilities, subsurface flow conditions, chemistry, nature and extent of the contamination, nutrient availability, etc. Bioremediation technologies, not specifically mycoremediation, have been/are utilized in... read more

What is the quality of the water discharged from the Pollock St well system into the Schuylkill?

Groundwater collected from the Pollack St well system is not discharged directly to the Schuylkill River. Groundwater discharged from any remediation system is either processed through the facility’s wastewater treatment plant which operates under a National Pollutant Discharge Elimination System (NPDES) permit held by PES or discharged to the Philadelphia Water Department (PWD) sewer system via a Groundwater... read more
