Municipality/County: Doylestown, Plumstead & Buckingham townships, Bucks County
HSCA Site Since: 2016
Why is DEP Investigating?
- In May 2016, after a public supply well in the area was found to contain combined concentrations of Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS) that exceeded EPA's 70 ppt Health Advisory Level (HAL), DEP immediately took steps to begin a thorough investigation of the surrounding area.
- DEP is investigating groundwater in the area to determine the extent of PFOA and PFOS in the aquifer underlying the area.
- We are referring to the Site as the Easton Run PFC HSCA Site. PFOA and PFOS are part of a larger class of chemicals known as perfluorinated compounds (PFCs) or per- and polyfluoroalkyl substances (PFAS).
Private Drinking Water Investigation
- 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.
- There are currently 8 homes whose private well water has exceeded the HAL.
- In April 2019, DEP completed an additional round of private well 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 that no additional homes had private well water with combined concentrations of PFOA/PFOS above the HAL.
- DEP is looking into all Potentially Responsible Parties. 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 provided below.
- In March 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, five (5) rounds of the groundwater sampling have been collected from the monitoring wells. Results of this sampling have ranged from non-detect (ND) to 69 ppt. The next round of monitoring well sampling is scheduled for winter 2020.
- DEP collected 24 surface water samples from locations along Pine Run and its tributaries. Results revealed no exceedances of the HAL.
Press Releases/Public Notification
What is DEP Doing to Address the Drinking Water Contamination?
DEP is supplying bottled water to 4 of the residential properties with private well water exceeding the HAL; the 4 other properties with private well water exceeding the HAL have elected to privately install filtration systems at their own expense to mitigate this contamination.
DEP is currently proposing the installation and maintenance of whole-house filtration systems as an Interim Response to address PFAS contamination in homes that have private well water above the HAL.
All of the information used to formulate its proposal has been incorporated into DEP’s Administrative Record. The administrative record process enables community members to have an opportunity to be heard concerning the cleanup or abatement of hazardous contaminants in their community.
The Administrative Record will be open for public comments for 90-days between October 19, 2019 and January 17, 2020.
- DEP held a public hearing on November 18, 2019 at the Lenape Middle School
* 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.
