Berkeley County (WV) near Shepherd Field Air National Guard Base
PFAS Exposure Assessment Community Level Results
New! In 2019, the Centers for Disease Control and Prevention (CDC) and the Agency for Toxic Substances and Disease Registry (ATSDR) started exposure assessments (EAs) in communities near current or former military bases known to have had per- and polyfluoroalkyl substances (PFAS) in their drinking water. Individuals who participated in the EAs provided blood and urine samples to CDC/ATSDR for analysis. We sent letters to participants that included their individual lab results. An example letter of the test results letter and the community level results are available here.
The Shepherd Field Air National Guard Base previously used aqueous film-forming foam containing PFAS to fight fires and train workers. These compounds later moved off-site in groundwater, likely affecting the City of Martinsburg’s Big Springs well. Drinking water from this well supplies both City of Martinsburg and a small percentage of Berkeley County customers. Residents who may have been affected include those who live in areas south of the Big Springs treatment plant and those City of Martinsburg residents who are connected to the municipal water supply and live west of Interstate 81 (I-81) or in the Amber Woods housing complex (east of I-81).
PFAS was first detected in the Big Springs well in February 2014. Levels did not exceed the U.S. Environmental Protection Agency (EPA) provisional health advisory level (level used in 2014). In 2016, EPA issued a health advisory (HA) for the sum of two PFAS compounds — perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) —at 70 parts per trillion (ppt). This prompted the City of Martinsburg to take its Big Springs well out of service until a treatment system was installed to remove PFAS from the well water. Martinsburg now conducts routine monitoring to ensure treatment is effectively removing PFAS to levels well below the revised health advisory. In 2017, the West Virginia Department of Environmental Protection (WVDEP) tested for PFOS/PFOA in private well water in the vicinity of the base. All water sample results were below EPA’s HA for PFOS and PFOA.
Participating in an exposure assessment will help you and your community better understand the extent of environmental exposures to PFAS. A random selection of households impacted by PFAS in their drinking water will be identified. If your household is selected to participate, you will receive a letter in the mail from CDC/ATSDR explaining the exposure assessment and registration process. You will also get a phone call from a representative who can answer questions and register you and other members of your household interested in participating. Household members are eligible if they are 3 years of age or older, do not have a bleeding disorder and are not anemic, and have lived in the recruitment area since May 19, 2015. Inclusion of children in the exposure assessment is dependent on parent or legal guardian consent.
CDC/ATSDR began an exposure assessment in Berkeley County in summer 2019. Recruitment took approximately 6 weeks. CDC/ATSDR was in Berkeley County from September 24 through October 7, 2019 to test participants.
CDC/ATSDR completed the analysis of environmental and biological samples. Individual test results were mailed to participants on May 15, 2020. If you participated in the exposure assessment and have not received your individual test results, please contact ATSDR at PFAS@cdc.gov. CDC and ATSDR will write a final report summarizing the findings and recommendations for the community and present the results at a public meeting.
CDC/ATSDR held an information session to answer questions from the community, listen to concerns, and promote transparency and understanding.
