HHRA Evaluation of Six Townhomes

Location: Radnor Township, Delaware County, PA


HHRA Project Summary – Residential Redevelopment in Delaware County

 

In support of a Pennsylvania Department of Environmental Protection (PADEP) Act 2 Combined Remedial Investigation Report (RIR), Risk Assessment (RA), and Final Report (FR), Brickhouse performed a Baseline Human Health Risk Assessment (HHRA) for the future development of six townhomes in Radnor Township, Delaware County, PA.  The property is comprised of a mixture of commercial and residential properties and was most recently was used for storage of material by a swimming pool maintenance company.  Historic Site operations did not result in contamination; however, elevated concentrations of Polycyclic Aromatic Hydrocarbons (PAHs) were identified in historic fill during Phase II Environmental Site Assessment (ESA) soil sampling.  In an effort to benefit the public through employment opportunities during the redevelopment phase, as well as through future residential housing; a Baseline Human Health Risk Assessment (HHRA) was performed in order to demonstrate attainment of the Site-Specific Standard (SSS).

The HHRA was conducted in order to characterize the potential exposure and risks associated with Site soil to future human health receptors including construction/utility workers and child and adult residents. As an additional line of evidence, Brickhouse developed Site-specific cleanup standards for any cancer risk greater than 1E-06 or HI greater than 1.  Based on current conditions, Brickhouse was able to demonstrate attainment of the SSS for PAHs in soil without the need for further remedial actions and resulting additional costs to the client.
