Site Facts

Municipality/County: Doylestown, Plumstead & Buckingham townships, Bucks County
HSCA Site Since: 2016
Primary Contaminants of Concern: perfluorooctanoic acid (PFOA) & perfluorooctane sulfonate (PFOS) PFOA and PFOS are part of a larger class of chemicals known as perfluorinated compounds (PFCs) or per- and polyfluoroalkyl substances (PFAS).

Why is DEP Investigating?

  • In May 2016, after a public supply well in the area was found to contain combined concentrations of PFOA and PFOS that exceeded EPA's 70 ppt Health Advisory Level (HAL), DEP immediately took steps to begin a thorough investigation of the surrounding area.
    • Pennsylvania's Environmental Quality Board has not proposed a State Maximum Contaminant Level (MCL) at this time. If a State or Federal MCL is issued for PFOA or PFOS that is different from the HAL, DEP will reevaluate the Site and take action as necessary and appropriate.
  • DEP is investigating groundwater in the area to determine the extent of PFOA and PFOS in the aquifer underlying the area.

Private Drinking Water Investigation and DEP’s Response

  • Since May 2016, DEP collected samples from more than 350 private wells. Results of this sampling ranged from non-detect (ND) to 229 ppt combined for PFOA/PFOS.
  • DEP identified a localized area of concern within Doylestown Township where the highest concentrations of PFOA/PFOS have been detected.
  • To date, 8 homes in the area of concern have tested above the HAL.
  • In August 2020, DEP completed a round of residential sampling. The event included select homes within the localized area of concern whose private well water had combined concentrations of PFOA/PFOS above 40 ppt. The results revealed no additional homes with private well water above the HAL.
  • DEP's responsibility under HSCA is to select a remedy that is protective of human health and the environment and complies with all statutory and regulatory requirements.
  • The information DEP used to formulate its decision was incorporated into DEP’s Administrative Record.
  • The Administrative Record was open for public comment between October 19, 2019 and January 17, 2020.
    • Administrative Record (PDF)
    • Hard copies of the Administrative Record are available for public review at DEP’s Southeast Regional Office, and the municipal buildings for the local municipalities: Doylestown Township, Buckingham Township, Plumstead Township, and Doylestown Borough
  • DEP held a public hearing on November 18, 2019
  • On April 1, 2020, DEP determined the most appropriate interim response action to be the installation and maintenance of whole-house filtration systems to address PFOA/PFOS contamination exceeding the HAL. This response was formally selected in DEP’s Statement of Decision (SOD) and Response to Public Comments document.
  • Statement of Decision and Response to Public Comments (PDF)*
    • *These documents were subsequently mailed to all individuals who commented on the proposed response.
  • DEP considers this response to be an Interim Response as additional actions may be needed to achieve a complete and final cleanup for the Site.
  • To date, DEP’s contractor has completed the installation of whole house filtration systems in 2 homes, the replacement of 2 existing treatment systems and completed upgrades of 4 additional treatment systems.
  • Post treatment samples revealed that all treatment systems are removing PFOA/PFOS contamination from the drinking water supplies to non-detect levels.
  • DEP plans to monitor and maintain the systems for the duration of its ongoing investigation to ensure they are effectively removing PFOA/PFOS from the water supplies.

Source Investigation

  • DEP is looking into all Potentially Responsible Parties (PRPs). If you have any information related to any potential sources of PFAS contamination, please feel free to provide that information to DEP using the contact information at the bottom of this page.
  • In 2018, DEP completed the installation of 7 groundwater monitoring wells within the localized area of concern in Doylestown Township.
  • The purpose of these monitoring wells is to aid DEP in determining the nature and extent of groundwater contamination beneath the Site area.
  • To date, six (6) rounds of groundwater samples have been collected from the monitoring wells. Results of this sampling have ranged from non-detect (ND) to 72 ppt. Monitoring wells are sampled on an annual basis.
  • In November 2019, DEP collected soil, surface water, and groundwater samples from the Arbonite facility located at 3826 Old Easton Road in Buckingham Township. Based on initial results, DEP determined additional sampling and investigation is needed.
  • Through the course of the investigation DEP collected 24 surface water samples from locations along Pine Run and its tributaries. Results revealed no exceedances of the HAL.
