ATSDR Press Room

ATSDR invites public to comment on the Pease International Tradeport report

Portsmouth, Newington, and Greenland, New Hampshire

Monday, April 01, 2019

ATLANTA, GA - The Agency for Toxic Substances and Disease Registry (ATSDR) has released for public comment its health consultation report, “Per and Polyfluoroalkyl Substances (PFAS) in the Pease Public Water System,” in Portsmouth, Newington, and Greenland, New Hampshire. ATSDR will accept comments from the public until June 3, 2019.

The report concluded that workers at Pease International Tradeport and children attending the childcare centers were exposed to PFAS in contaminated drinking water at the Pease International Tradeport. Those exposures occurred from 1993 until the Haven well was shut down in May 2014. People exposed to drinking water from the Pease Tradeport Public Water System (PWS) during this period might be at increased risk for some harmful health effects. The cancer risk from past exposure to all PFAS in the Pease Tradeport PWS is uncertain.

Although the Haven well was shut down, low levels of PFAS remain in the water serving the Pease Tradeport PWS. Consuming water containing low levels of PFAS at Pease is not expected to harm people.  However, persons who have had long-term exposures to PFAS should be aware of ways to reduce further exposures. Information on ways to reduce exposures to all sources of PFAS is available at  

ATSDR staff will hold public availability sessions to discuss the report’s findings and recommendations with Pease International Tradeport workers and parents of children who attended the childcare centers.  It will also provide the community with an opportunity to speak with ATSDR scientists.
