Barnstable County health officials report high demand for PFAS and beach testing; free PFAS slots filled in 48 hours

Barnstable County health officials told commissioners on Aug. 27 that the county’s PFAS testing pilot filled its roughly 300 free slots within 48 hours, and that the beach-sampling program is concluding after collecting 350 samples across 15 communities.

"The 300 or so, we didn't know. It filled up in 48 hours," Jake Gardner, director of health and environment, said. He told the board that county staff are talking with the laboratory about options to offer paid testing to residents who did not receive free slots, and that staff may consider underwriting some tests to ensure affordability.

Gardner said the beach-sampling program will wrap up the week of the meeting; staff held an appreciation event for volunteers who collected samples. He said the county must ensure geographic distribution of PFAS sampling to avoid clustering samples on a single street and to produce useful data for community-level pattern detection.

Commissioners and staff discussed how test results may reveal elevated PFAS in some areas and that identifying a source can be complex; septic systems, household practices and other diffuse sources were cited as possible contributors. Gardner said the Department of Environmental Protection (DEP) will be a collaborative partner in follow-up actions where remediation or municipal planning is needed.

No new county appropriation for broader testing was voted at the meeting; staff said they will return with options for laboratory pricing and potential underwriting to expand access.
