How is ATSDR involved investigating PFAS in the environment?

ATSDR is involved at a number of PFAS-related sites, either directly or through assisting state and federal partners (Figure 1). As of now, most sites are related to drinking water contamination connected with PFAS production facilities or fire training areas where aqueous film-forming firefighting foam (AFFF) was regularly used. We are working with one state partner on a site where consuming contaminated fish is the concern.

Examples include:

Region 1

Merrimack Area of Southern New Hampshire (NH)

The New Hampshire Department of Environmental Services (NHDES) tested public and private drinking water supplies in the Merrimack area that may have been contaminated by discharges from nearby factories. Some of the wells are contaminated with PFOA (perfluorooctanoic acid). ATSDR is evaluating the test results to determine if drinking the water may harm people’s health and will provide the findings in a written report.

Background on the investigation is available via the NHDES website at https://www4.des.state.nh.us/nh-pfas-investigation/

Pease International Tradeport (aka Former Pease Air Force Base) (NH)

The City of Portsmouth, working with the NH Department of Environmental Services and the NH Department of Health and Human Services (NH DHHS), tested the Pease International Tradeport drinking water wells for PFAS (per- and polyfluoroalkyl substances) in May 2014. One of three wells had elevated levels of PFOS (perfluorooctane sulfonic acid). The City of Portsmouth took the well off-line. PFAS were found in the other Tradeport wells, and in some residential private drinking water wells located near the site. Aqueous film-forming foam (AFFF), a fire suppressant agent used at the former Pease Air Force Base, is the presumed source of PFAS. ATSDR will evaluate the test results from contaminated city and private wells to determine if drinking water from these wells may harm people’s health. They will provide their findings in written reports. ATSDR has created a Community Assistance Panel (CAP) to receive input from community members about health studies.

For more information, visit the CAP website at http://www.atsdr.cdc.gov/sites/pease/cap.html

The NH DHHS provides information about the site at http://www.dhhs.nh.gov/dphs/investigation-pease.htm In 2015, NH DHHS tested the blood of people who worked on, lived on, or attended childcare on the Pease Tradeport or Pease Air Force Base, and drank water from contaminated wells. A copy of the report is available at http://www.dhhs.nh.gov/dphs/documents/pease-pfc-blood-testing.pdf

North Bennington PFOA Well Water (VT)

The Vermont Department of Environmental Conservation (VDEC) found PFOA (perfluorooctanoic acid) in private drinking water wells in North Bennington. PFOA is one of the chemicals in the PFAS (per- and polyfluoroalkyl substances) family. VDEC is testing private wells within a 1.5-mile radius of the former ChemFab site, which is the source of the PFOA, to see how widespread the contamination is. The Vermont Department of Health (VDH) asked NCEH/ATSDR for technical support in addressing health issues.

Region 3

Naval Air Development Center, Warminster TWP (PA)

Groundwater at the former Naval Air Warfare Center Warminster site is contaminated with PFAS (per-and polyfluoroalkyl substances). The Environmental Protection Agency (EPA) and the Navy tested private drinking water wells in Warminster, and the Warminster, Ivyland, Warwick, Northampton and upper Southampton townships. Some of the wells are contaminated with PFAS. Public water utilities continue to test water samples from their systems. The source of PFAS in the groundwater is likely past use of aqueous film-forming foam (AFFF) in the area. In 2016, ATSDR produced a letter health consultation that evaluated the available off-site water test results. The report is available at http://www.atsdr.cdc.gov/HAC/pha/NavalAirWarfareCenter/Naval_Air_Warfare_Center_LHC_01-20-2016_508.pdf

ATSDR is working with the Mid Atlantic Center for Children’s Health and the Environment to answer health questions and to educate local health professionals about potential health effects caused by exposure to PFAS. In addition, ATSDR has worked with the PA Department of Health to summarize available cancer statistics for this area. The 2016 cancer data review for selected zip codes of Warminster, Warrington, and Horsham, PA, is available at https://www.atsdr.cdc.gov/HAC/pha/CancerDataReviewPA/CancerDataReview_PA_508.pdf PADOH is continuing to provide updates on the cancer information for this community at http://www.health.pa.gov/My%20Health/Environmental%20Health/Pages/default.aspx#.WgDCz2hOmEc

Willow Grove NAS and ARS (PA)

Groundwater at the Willow Grove Air Station Joint Reserve Base is contaminated with PFAS (per‐ and polyfluoroalkyl substances). Some public water supply wells in Horsham and Warrington Townships are contaminated, and the utilities continue to test the water in their systems. The Department of Defense asked the Environmental Protection Agency (EPA) to test private well water near the site.  Some private wells in Horsham, Warminster and Warrington are contaminated with PFAS. The source of PFAS is likely a result of past use of aqueous film-forming foam (AFFF) in the area.

EPA asked ATSDR to evaluate PFAS water sampling results in the public and private wells. ATSDR is currently preparing a report that reviews the public and private drinking water results.

ATSDR is working with the Mid Atlantic Center for Children’s Health and the Environment to answer the community’s health questions and to educate local health professionals about possible health effects caused by exposure to PFAS. ATSDR continues to work with the PA Department of Health to summarize available cancer statistics for this area because community members are concerned about cancer in their community.

Wallops Flight Center – NASA (VA)

The NASA Wallops Flight Center is located on Wallops Island, VA, near the Town of Chincoteague (ToC). Two of the three ToC shallow wells, and the deep well adjacent to them, are contaminated with PFAS (per‐ and polyfluoroalkyl substances) above the EPA Lifetime Health Advisory (HA) for perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). The shallow wells, and the adjacent deep well are no longer being used for drinking water. Samples collected between the NASA fire training area and a residential community west of the facility contained traces of PFOA and PFOS that were below the HA.

The NASA and ToC water supplies were tested in October 2017, and sample results indicate there are no detectable levels of PFOA or PFOS in the finished drinking water. NASA will continue to test drinking water supplies for PFAS. NASA is installing groundwater monitoring wells to monitor PFAS levels in the shallow groundwater along the site perimeter. There are several oyster beds near the NASA Wallops Flight Facility and the local population is concerned about whether the PFAS contamination might be impacting the oyster industry.  Surface water and sediment will be tested for PFAS in the fall or winter of 2018.  ATSDR is providing public health education support.

US Naval Auxiliary Landing Field Fentress (VA)

In January 2016, the Navy sampled groundwater monitoring wells and the on-base drinking water wells at Naval Auxiliary Landing Field Fentress (NALF). PFOS (perfluorooctane sulfonate) and PFOA (perfluorooctanoic acid) were detected in the monitoring wells and on-base drinking water supply wells). The NALF drinking water supply wells were shut down and the base supplied with bottled water. Private wells located off-site were sampled, and some wells were above the EPA Lifetime Health Advisory (HA) for PFOS and PFOA. The Navy is providing alternative water to residences with contaminated wells, and is sampling the wells quarterly. The source of the PFAS is aqueous film-forming foam (AFFF) used for firefighting exercises conducted at the site. The Navy has installed a total of 47 on-base groundwater monitoring wells for further delineation of PFAS.

The Navy will be sampling additional private wells near the base in 2018.  ATSDR and the Virginia Department of Health will evaluate test results when available.

For more information, visit the Navy website at https://www.cnic.navy.mil/regions/cnrma/installations/nas_oceana/om/environmental_support/NALF_fentress_drinking_water.html

Oceana Naval Air Station (NAS Oceana) (VA)

Groundwater at the NAS Oceana was tested for PFAS (per‐ and polyfluoroalkyl substances), following detections of PFAS at nearby Fentress. On-site sampling found PFOS (perfluorooctane sulfonate) and PFOA (perfluorooctanoic acid) combined exceeding the EPA Lifetime Health Advisory (HA) for PFOS and PFOA. Off-site sampling did not detect levels above EPA’s Lifetime HA. The source of the PFAS is aqueous film-forming foam (AFFF) used in training activities at the site. ATSDR is providing health education and technical support activities at the site.
