Maine, USA, October 2025 — Maine has launched a groundbreaking free PFAS blood testing program for over 600 households and farmers exposed to elevated levels of “forever chemicals,” marking a critical shift from contamination tracking to direct medical intervention.
Program Overview
The initiative, led by the Fund to Address PFAS Contamination—a $60 million fund created by Governor Janet Mills in 2022—will cover blood testing costs that typically range from $400 to $600 per test. The state allocated approximately $400,000 for this first round of testing, with $7.3 million designated for direct medical costs overall.
Eligibility Criteria
According to Beth Valentine, fund director, eligible participants include:
- Commercial farmers or farmhands who worked on commercial farms
- Residents whose well water tested above the state drinking water standard of 20 parts per trillion (ppt) for six specific PFAS compounds
- Residents whose soil tested above 170 parts per billion (ppb) of PFOS
- Non-farm residents whose PFAS exposure is linked to land application of biosolids (sewage sludge)
Letters were sent in September 2025 to identified households informing them of their eligibility.
Health Implications
PFAS blood testing provides critical baseline information for exposed individuals. The National Academies of Sciences, Engineering, and Medicine (NASEM) reported potential adverse health effects in people with PFAS blood levels between 2 and 20 nanograms per milliliter (ng/mL), with increased risk above 20 ng/mL.
Health effects associated with PFAS exposure include:
- Elevated cholesterol levels
- Kidney and testicular cancer
- Liver damage
- Thyroid dysfunction
- Reproductive issues
- Decreased birth weight
- Reduced antibody response to vaccines
Individuals testing above 20 ng/mL will be encouraged to schedule regular screenings for specific cancers and health conditions based on age.
Contamination Background
The PFAS contamination stems primarily from the historical use of sewage sludge as agricultural fertilizer across Maine farms. More than 90 Maine farms have been found to have PFAS-contaminated soil or water. The state identified approximately 700 sites where biosolids were applied, with nearly three dozen “Tier 1” towns at higher contamination risk.
In 2022, Maine passed legislation making new sludge application illegal, effectively “turning off the tap” of these contaminants on farmlands.
Additional Support Programs
Beyond blood testing, the PFAS Fund is developing mental health support services for affected farmers and residents. The fund also provides:
- Financial assistance for water filtration systems
- Income replacement for impacted farms
- Infrastructure investment support
- Reimbursement for PFAS testing expenses
Advocacy efforts continue to expand insurance coverage for PFAS testing to make it more accessible long-term.
National Significance
Maine’s comprehensive approach positions the state as a national leader in addressing agricultural PFAS contamination. The blood testing program represents the first state-funded initiative of its kind in the country, potentially serving as a model for other states facing similar contamination challenges.
