Listening Session Summary
Listening Session Welcome and Introduction
Cosmo Servidio, Administrator, EPA Region 3, welcomed and thanked community members and
groups, state and local officials, and elected officials for their attendance and participation. Mr. Servidio
articulated that the purpose of the EPA's listening session was to engage with communities and receive
their input to develop EPA's National PFAS Management Plan.
Dr. Peter Grevatt, Director, EPA, Office of Ground Water and Drinking Water, thanked participants for
coming to the event to share perspectives. Dr. Grevatt emphasized EPA's commitment to finding
solutions by working across the entire Agency and with local, state, and federal partners. Dr. Grevatt
stressed the EPA's intent to develop a PFAS Management Plan, to better coordinate federal efforts, and
to listen and learn from impacted communities. Dr. Grevatt described EPA's commitments announced at
the PFAS National Summit:
•	EPA will initiate steps to evaluate the need for a maximum contaminant level (MCL) for PFOA
and PFOS.
•	EPA will initiate the necessary steps to propose designating PFOA and PFOS as "hazardous
substances" through one of the available statutory mechanisms, including potentially CEP,CLA
Section 102.
•	EPA is currently developing groundwater cleanup recommendations for PFOA and PFOS at
contaminated sites.
•	EPA is acting in close collaboration with federal and state partners to develop toxicity values
for GenX and PFBS.
Dr. Grevatt informed participants that EPA has a docket (http://www.regulations.gov: enter Docket ID
No. EPA-OW-2018-0270) available to provide comments on the development of EPA's National PFAS
Management Plan.

Ongoing PFAS Research and Federal Panel on PFAS Activity
A panel of federal officials reviewed ongoing research at EPA and the Agency for Toxic Substances and
Disease Registry (ATSDR) and the work currently underway at US Department of Defense sites in
addressing PFAS.
•	Dr. Andy Gillespie, Associate Director, EPA, Office of Research and Development (ORD),
described the five areas EPA ORD is researching: analytical methods, exposure pathways, human
health/toxicity, treatment/remediation approaches, and technical assistance opportunities.
•	Maureen Sullivan, Deputy Assistant Secretary of Defense, Department of Defense (DoD),
Environment, Safety & Occupational Health Office of the Assistant Secretary of Defense,
described the ongoing work to address PFAS associated with DoD sites. The presentation
described the status of pending health studies.
•	Lora Werner, Director, Region 3, and Dr. William (Bill) Cibulas, Director, Agency for Toxic
Substances and Disease Registry (ATSDR), Division of Toxicology and Human Health Sciences,
emphasized the importance of listening and acting on community needs. Their presentation
indicated that there is still much more health data to gather on PFAS, and that many new health
studies are being conducted and completed. The presentation indicated that ATSDR is planning
a multi-site epidemiologic study and is currently in the process of writing study protocols.
State Panel on PFAS Activity
State officials provided an overview of PFAS issues and challenges in Pennsylvania, Maryland, Delaware,
and West Virginia. The presentations are available at: https://www.epa.gov/sites/production/files/2018-

•	Sharon Watkins, Pennsylvania Department of Health
•	Todd Keyser, Delaware Department of Natural Resources and Environmental Control
•	Keith Mensch, Delaware Department of Health
•	John Grace, Maryland Department of the Environment
•	Scott Mandirola, West Virginia Department of Environmental Quality
Local Panel on PFAS Activity in the Warminster/Willow Grove/Horsham Area
Local government/township officials and water authorities provided EPA with feedback regarding their
experiences with PFAS in the Horsham/Warwick/Warminster/Warrington Townships. Officials discussed
PFAS in their community. They provided information regarding PFOA and PFOS that were detected
above the Health Advisory level in Horsham, Warminster, and Willow Grove during the UCMR3
sampling. They demonstrated how the towns quickly acted to provide safe drinking water by switching
sources and/or installing GAC to treat water from contaminated wells. They summarized information
regarding the source of contamination and how it was traced to the military facilities. They also
indicated that the Department of Defense has been cooperating with the state and local authorities to
address the issue and provide safe water, including connecting most homes with private wells that
tested above the Health Advisory Level to the public water supply. However, they expressed frustration
at the speed which DoD, and to some extent, EPA, are getting things done to address PFAS.

Community Listening Session
Cosmo Servidio and Peter Grevatt welcomed community members and groups and articulated the
importance of the listening sessions in developing EPA's National PFAS Management Plan. The session
was kicked off with a video from Congressman Boyle (PA 13th district).
Close to 50 community members shared input during the community listening session. The following is a
synthesized list of themes and points shared during the listening session:
Health Impacts
Community members spoke about health problems in their families and their communities.
Commenters shared their individual experiences and discussed the health and economic impacts to
their families. They urged the EPA to further investigate the high frequency of occurrence of negative
health impacts in the community. Others noted that there is no clear determination of past
concentrations and exposure, which they felt may be much higher, resulting in serious health impacts. In
addition to current and past health impacts, commenters also stated that they were fearful of future
and ongoing exposure. Several commenters spoke to the need for long-term comprehensive
biomonitoring. They recommended EPA take proactive measures to identify and treat community health
impacts associated with PFAS, including their desire to be included in upcoming health studies.

Private Wells
Community members expressed that risk characterization is important for private well owners. They
expressed concerns with the costs to install a carbon filter and recommended that the cost burden for
remediation for wells that test below the Health Advisory Level, and therefore have not been connected
to the public water supply, should be covered upfront by producers and users of PFAS, rather than
private individuals. Commenters asked for information or mapping on contaminated areas to better
support decision making, such as where to drill private wells.
Risk Communication
Community members expressed the need for more effective communications and greater transparency.
Some commenters expressed frustration with the lack of timely guidance and information. Others felt
the communications were inconsistent and ineffective. Commenters pointed to the lack of trust
between regulators and community as a barrier to communication. They urged the EPA to rebuild trust
through action, first by providing funding and testing, and second by developing guidelines and
communication resources. There is confusion about different numbers and standards, which leaves
community members hesitant to drink the water in their homes.
Standards/Guidance
Community members recommended that EPA regulate or address PFAS as a family of chemicals, rather
than review each chemical separately. They urged EPA to develop MCL(s) rather than health advisories
to better enable drinking water utilities to take action. There was a collective desire for EPA to develop
national guidance to protect families and communities across the country. By providing regulators an
enforceable standard, commenters felt the EPA would be better able to safeguard human health and
the environment. Community members urged that PFAS and associated chemicals be listed as
hazardous substances.
Cost Impacts
Community members identified the cost impacts to their families and community from PFAS. They
indicated that they are bearing the cost of the cleanup and increased costs of health care. Commenters
expressed that the polluters should be responsible for costs. They shared their frustration at the high
cost PFAS contamination has had on health and finances. They urged the EPA to consider the stories of
the people behind the statistics and data. Commenters identified the need for additional funding for
states to support health monitoring. They encouraged the EPA to fast-track the development of
treatment solutions. Additionally, many commenters stated that they were fearful of their exposure and
for the potential for future medical problems. Commenters noted that military members that formerly
lived in the area may have been exposed and should be contacted and provided support.
Remediation
Community members expressed a sense of urgency to deal with the issues including cleanup deadlines.
They felt that remediation timelines should be aligned at Horsham Air Guard Station/former Naval
Station Joint Reserve Base - Willow Grove and former Naval Air Warfare Center - Warminster. They
recommended that remediation at these sites be expedited as the health, wellbeing, and economic
development of the community depended on it. One commenter pointed to the need for
comprehensive remediation and treatment, which would include addressing PFAS in air, soil, and water.
Community members expressed that source water protection is critical, including treatment of
wastewater and storm water from the military bases.
