Notice of Proposed Interim Response
Ridge Run PFAS HSCA Site, East & West Rockhill Townships, Bucks County

Public Hearing July 11 at 6:30 p.m.

 The Department of Environmental Protection (Department), under the authority of the Hazardous Sites Cleanup Act (HSCA) (35 P.S. §§ 6020.101—6020.1305), is proposing an interim response at the Ridge Run PFAS HSCA Site, East and West Rockhill Townships, Bucks County, PA. The Site is located along Old Bethlehem Pike, Bethlehem Pike, Tabor Road, Hill Road and North Rockhill Road. The Ridge Run PFAS Site includes approximately 12 private wells impacted with per- and poly-fluorinated alkyl substances (PFAS) above the Health Advisory Limit (HAL) combined concentration for Perfluorooctane sulfonate (PFOS) and Perfluorooctanoic acid (PFOA) of 70 nanograms per liter (ng/L) or parts per trillion (ppt). The area of the Site consists mostly of residential properties mixed with several commercial properties.


 In August of 2016, the North Penn Water Authority (NPWA) conducted sampling for PFAS in two public water supply wells in East Rockhill Township in accordance with the Federal Unregulated Contaminant Monitoring Rule (UCMR3). Analysis of these samples detected combined concentrations of PFOS and PFOA of 117 ng/L and 70 ng/L, both at or above the HAL. Approximately 156 homes have been sampled by the Department in the subsequent investigation of the surrounding area. Twelve properties have been impacted above the HAL. The highest combined concentration detected was 11,320 ng/L. No source area has yet been identified. The Department is continuing to sample homes affected by the contamination to monitor concentrations at the Site. In addition to the 12 properties impacted above the HAL, two other properties with concentrations above 40 ng/L have continued to be monitored for seasonal fluctuations. The Department has also been providing bottled water to impacted homes. The owners of two of the affected homes have installed their own carbon filtration units, which have been effective at reducing the levels of contamination below the HAL.


 To address the release or substantial threat of release of contaminants at the Site, and corresponding threats to human health and the environment, the Department proposes an interim response action at the Site under section 501(a) of HSCA (35 P.S. § 6020.501(a)). The Department hereby proposes the installation of whole house carbon filtration units on affected private residential water supplies with concentrations exceeding the HAL. This proposed alternative complies with Applicable, Relevant and Appropriate Requirements (ARAR) and is feasible and cost-effective. Other possible alternatives include taking no action, the installation of a public waterline and continuing to provide bottled water.


 This notice is being provided pursuant to section 506(b) of HSCA. The administrative record which contains the information that forms the basis and documents the selection of this response action is available for public review and comment. The administrative record is located at the Department's office at 2 East Main Street, Norristown, PA 19401 and is available for review Monday through Friday from 8 a.m. until 4 p.m. Those interested in examining the Administrative Record at the Department's office should contact Lena Harper at (484) 250-5721 to arrange for an appointment. Additional copies of the Administrative Record are available for review at the East Rockhill Township Office, 1622 Ridge Road, Perkasie, PA 18944, the West Rockhill Township Office, 1028 Ridge Road, Sellersville, PA 18960 and on the Department's web site at www.dep.pa.gov/pfcs.


 The administrative record will be open for comment from June 2, 2018, until August 31, 2018. Persons may submit written comments into the record during this time only, by sending them to Lena Harper, Environmental Protection Specialist at the Department of Environmental Protection, 2 East Main Street, Norristown, PA 19401, lharper@pa.gov. In addition, persons may present oral comments, for inclusion in the administrative record, at the public hearing. The Department has scheduled the hearing on July 11, 2018, at 6:30 p.m. at the West Rockhill Township Building, 1028 Ridge Road, Sellersville, PA 18960.
