Project Description

Whitestone has designed, coordinated, and overseen remedial action efforts to obtain liability protection for sites throughout Pennsylvania including the following representative projects:

Borough of Royersford

This project included the removal of two 2,500-gallon heating oil USTs that had leaked and impacted soil in the vicinity of the tanks. Contaminated soil was excavated and transported off-site for treatment/disposal and a groundwater investigation was initiated per PADEP requirements. Three groundwater monitor wells were installed and sampled, documenting that groundwater conditions had not been impacted by the leaking USTs. This information was submitted to PADEP and liability protection was obtained under the Act 2 Program.

City of Philadelphia

Whitestone’s client intended on purchasing and continuing the operation of an on-site quick-serve restaurant at this Philadelphia location. During due diligence investigations, Whitestone identified soil contamination in the existing drive-thru area resulting from historic gasoline USTs which had previously been removed. Whitestone conducted soil and groundwater remedial investigation activities and identified an area of impacted soil requiring remediation. At the client’s request, impacted soil was excavated and removed and transported off-site for treatment/disposal in order to avoid an Environmental Covenant. Liability protection was obtained under state-wide health standards for both soil and groundwater. Site investigation and remediation activities were conducted at night and off-hours to avoid disturbance of restaurant business operations.

City of Philadelphia

The project included the remediation of tetrachloroethylene (PCE) contaminated soil and groundwater resulting from a leaking PCE UST which was encountered during site redevelopment activities. Soil remediation activities included excavation and off-site treatment/disposal of the source area soil and in-situ chemical oxidation for the remaining impacted site soils and site groundwater. On-site and off-site groundwater investigation and quarterly sampling was performed, and fate and transport modeling was used to document no receptors. Liability protection was received for soil under state-wide health standards and groundwater under site-specific standards with an Environmental Covenant executed for groundwater.

Northampton Township

This project included the removal of five heating oil USTs immediately adjacent to an operating retail structure. Soil impacted by the leaking USTs was excavated down to bedrock and along the edge of the building foundation. Whitestone applied the 75/10x statistical test to demonstrate attainment of state-wide health standards for site soil. Free product was encountered on groundwater and a product recovery program was instituted along with quarterly groundwater sampling and analyses. Based on the removal of free product and fate and transport modeling demonstrating no receptors, liability protection was obtained under state-wide health standards for soil and site-specific standards for groundwater with an Environmental Covenant executed for groundwater. Whitestone was also able to demonstrate that MTBE contamination on site was the result of a nearby gasoline station and was not the responsibility of the property owner/Whitestone’s client.
