  • 12/23/19 - ATSDR’s updated protocol for the multi-site study was published in the Federal Register for a 30 day comment period:
  • 12/220/19 - ATSDR has updated PFAS guidelines for clinicians
  • 9/2019 - In September 2019, CDC/ATSDR awarded research funding to seven recipients for the PFAS multi-site health study.  A team including the Pennsylvania Department of Health, RTI International and Temple University was selected to look at exposures in Montgomery and Bucks Counties. This study will expand the science about the relationships between PFAS exposure and certain health outcomes and it will help people better understand their risk for health effects.  CDC/ATSDR is in the process of finalizing the multi-site research protocol that all the research recipients will follow.  Similar to other research studies, the first year includes preparation for recruitment strategies, data collection and management and community involvement while the study recipients are finalizing all necessary approvals.  More information about the multi-site study is available on CDC/ATSDR’s website at

In 2019, CDC/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. In May and June 2020, CDC/ATSDR began sharing results from the testing from the first four communities (MA, WV, DE, and WA).  Additional information is still being reviewed, such as age and location, to better understand each community’s exposure. Once the full analysis is complete, CDC/ATSDR will share our findings and recommendations in a report for each community.

Summary information for the initial results from these communities are available at:
