Pease Study

alert icon

The CDC/ATSDR Pease Study restarted on October 15, 2020 after a brief pause to implement safety measures for all staff and participants in response to the COVID-19 virus.

CDC and ATSDR have implemented these safety precautions in the testing process to protect staff and participants and to minimize the potential spread of COVID-19. Safety measures include a required screening of all staff and participants for COVID-19 signs and symptoms. This will include temperature checks before entering the office, a questionnaire, and the required wearing of masks and social distancing at all times while in the office. Hand washing stations and hand sanitizer will also be available.

Appointments will be rescheduled for those participants who had their appointments postponed. CDC and ATSDR continue to encourage interested community members to participate in the Pease Study by calling (603) 846-6192.

The Pease Study is the first site of the national, Multi-site Study, which will look at the human health effects of PFAS exposure through drinking contaminated water. CDC and ATSDR will use the Pease Study to evaluate and improve procedures and methods for the Multi-site Study design.

The Pease Study is now enrolling participants who meet specific eligibility requirements. This study will expand our scientific understanding of PFAS by looking at the association between health outcomes and PFAS exposure from drinking water. 

If you would like to enroll in the study or if you are unsure about whether you qualify for the study, please call the Pease Study call center at 603-846-6192. The call center will screen you for eligibility and provide information on the next steps.

Background 

Approximately 8,000 people work at or frequent the Pease International Tradeport. There are also two daycare centers located on the site. In May 2014, drinking water wells that supply the Pease International Tradeport were sampled. The Haven Well, one of three wells that serves the Pease International Tradeport and the New Hampshire Air National Guard base at Pease, showed elevated levels of the unregulated contaminant perfluorooctane sulfonic acid (PFOS). How long PFOS may have been present in this well is not clear. 

Because the level of PFOS exceeded the “provisional health advisory” set by the U.S. Environmental Protection Agency (EPA), the well was shut down by the City of Portsmouth on May 12, 2014, and since that time it has been physically disconnected from the system. The New Hampshire Department of Health and Human Services asked the Agency for Toxic Substances and Disease Registry (ATSDR) to help evaluate possible follow-up actions.
