When Lawrence and Penny Higgins of Fairfield, Maine, first realized in 2020 that prime ranges of poisonous chemical substances known as PFAS taint their house’s properly water, they puzzled how their well being may undergo. They had consumed the water for many years, given it to their pets and cattle, and used it to irrigate their vegetable backyard and fruit bushes.
“We wanted to find out just what it’s going to do to us,” Penny Higgins stated. They contacted a few medical doctors, however “we were met with a brick wall. Nobody knew anything.”
Worse nonetheless, she added, they “really didn’t want to hear about it.”
Many clinicians stay unaware of the well being dangers linked to PFAS, brief for perfluoroalkyl and polyfluoroalkyl substances, regardless of rising medical and public consciousness of the chemical substances and their toxicity. PFAS can have an effect on practically each organ system and linger in our bodies for many years, elevating dangers of most cancers, immune deficiencies, and being pregnant problems.
These “forever chemicals” have been extensively used because the Nineteen Fifties in merchandise together with cosmetics, cookware, clothes, carpeting, meals packaging, and firefighting foam. Researchers say they permeate water systems and soils nationwide, with a federal research estimating that at the very least 45% of U.S. tap water is contaminated. PFAS may be detected within the blood of nearly all Americans, based on the Centers for Disease Control and Prevention.
Maine was among the first states to start intensive water and soil testing and to attempt to restrict additional public publicity to PFAS through policy action, after discovering that farms and residences — just like the Higgins’ property — had been contaminated by land-spreading of wastewater sludge containing PFAS. Exposure can be excessive for individuals dwelling close to army bases, fireplace coaching areas, landfills, or manufacturing amenities.
In areas the place testing reveals PFAS hot spots, medical suppliers may be caught flat-footed and sufferers left adrift.
Rachel Criswell, a household apply physician and environmental well being researcher, is working to vary that. She was finishing her residency in Central Maine across the time that the Higginses and others there started discovering the extent of the contamination. Her medical coaching at Columbia University included greater than a 12 months in Norway researching the results of PFAS and different chemical substances on maternal and toddler well being.
When sufferers started asking about PFAS, Criswell and the state toxicologist provided major care suppliers lunchtime shows on the best way to reply. Since then, she has fielded frequent PFAS questions from medical doctors and sufferers all through the state.
Even educated suppliers can discover it difficult to remain present given quickly evolving scientific data and few established protocols. “The work I do is exhausting and time-consuming and sometimes frustrating,” Criswell stated, “but it’s exactly what I should be doing.”
Phil Brown, a Northeastern University sociology professor and a co-director of the PFAS Project Lab, stated the medical group “doesn’t know a lot about occupational and environmental health,” including that “it’s a very minimal part of the medical school curriculum” and persevering with training.
Courtney Carignan, an environmental epidemiologist at Michigan State University, stated studying of PFAS publicity, whether or not from their ingesting water or occupational sources, “is a sensitive and upsetting situation for people” and “it’s helpful if their doctors can take it seriously.”
Clinical steering regarding PFAS improved after the National Academies of Sciences, Engineering, and Medicine launched a report on PFAS in 2022. It discovered sturdy proof associating PFAS with kidney most cancers, excessive ldl cholesterol, diminished start weights, and decrease antibody responses to vaccines, and a few proof linking PFAS to breast and testicular most cancers, ulcerative colitis, thyroid and liver dysfunction, and pregnancy-induced hypertension.
That steering “revolutionized my practice,” Criswell stated. “Instead of being this hand-wavey thing where we don’t know how to apply the research, it brought a degree of concreteness to PFAS exposure that was kind of missing before.”
The nationwide academies affirmed what Criswell had already been recommending: Doctors ought to order blood assessments for sufferers with identified PFAS exposures.
Testing for PFAS in blood — and for associated medical circumstances if wanted — can assist ease sufferers’ anxiousness.
“There isn’t a day that goes by,” Lawrence Higgins stated, “that we don’t think and wonder when our bodies are going to shut down on us.”
‘Devastating but Incredibly Helpful’
After discovering out in 2021 that his household was exposed to PFAS by way of sludge unfold on their Unity, Maine, farm a long time earlier, Adam Nordell found that “it was exceedingly difficult” to get examined. “Our family doctor had not heard of PFAS and didn’t know what the test was,” he stated. A lab technician wanted teaching from an out of doors professional to supply the take a look at. The lab analyzing the samples had a backlog that left the household ready three months.
“The results were devastating but incredibly helpful,” Nordell stated. Their blood serum ranges for PFAS have been at roughly the 99th percentile nationally, far increased than their well-water ranges would have predicted — indicating that further publicity was most likely coming from different sources reminiscent of soil contact, mud, and meals.
Blood ranges of PFAS between 2 and 20 nanograms per milliliter could also be problematic, the nationwide academies reported. In extremely contaminated settings, blood ranges can run upward of 150 instances the 20-ng/mL danger threshold.
Nordell and his household had been planning to stay on the farm and develop crops much less affected by PFAS, however the take a look at outcomes persuaded them to go away. “Knowledge is power,” Nordell stated, and having the blood information “gave us agency.”

The nationwide academies’ steering paved the way in which for extra clinicians to order PFAS blood tests. The value, sometimes $400 to $600, may be prohibitive if not picked up by insurance coverage, and never all insurers cowl the testing. Deductibles and copays also can restrict sufferers’ capability to get examined. Less expensive finger-prick assessments, administered at house, seem to seize a few of the extra generally discovered PFAS as precisely as blood serum assessments, Carignan and colleagues found.
Maine legislators not too long ago passed, with overwhelming support, a invoice — modeled after one in New Hampshire — that may require insurers to contemplate PFAS blood testing a part of preventive care, however it was carried over to the following legislative session.
“In my mind, it’s a no-brainer that the PFAS blood serum test should be universally offered — at no cost to the patient,” stated Nordell, who now works as a marketing campaign supervisor for the nonprofit Defend Our Health. Early screening for the ailments related to PFAS, he stated, is “a humane policy that’s in the best interests of everyone involved” — sufferers, suppliers, and insurance coverage firms.
Criswell tells colleagues in household apply that they will view elevated PFAS blood ranges as a danger issue, akin to smoking. “What’s challenging as a primary care doctor is the nitty-gritty” of the testing and screening logistics, she stated.
In trainings, she shares a handout summarizing the nationwide academies’ steering — together with related heath circumstances, blood testing, scientific follow-up, and publicity discount — to which she has added particulars about lab take a look at order codes, insurance coverage prices and protection, and water filtration.
Criswell served on an advisory committee tasked with allocating $60 million in state funds to handle PFAS contamination from previous sludge-spreading in Maine. The group beneficial that labs analyzing PFAS blood assessments ought to report the outcomes to state public well being authorities.
That change, slated to take impact this summer season, will permit Maine well being officers to comply with up with individuals who have excessive PFAS blood ranges to higher decide potential sources and to share data on well being dangers and medical screening. As with many earlier PFAS policies, Maine is among the many first states to undertake this measure.
Screening for PFAS is falling brief in lots of locations nationwide, stated Kyle Horton, an internist in Wilmington, North Carolina, and founding father of the nonprofit On Your Side Health. She estimates that solely about 1 in 100 individuals dealing with excessive PFAS publicity are getting ample medical steering.
Even in her highly contaminated community, “I’m not aware of anyone who is routinely screening or discussing PFAS mitigation with their patients,” Horton stated. Knowledge of native PFAS threats, she added, “hasn’t translated over to folks managing patients differently or trying to get through to that next phase of medical monitoring.”
Patients as Advocates
In closely affected communities — together with in Michigan, Maine, and Massachusetts — sufferers are pushing the medical area to higher perceive PFAS.
More medical doctors are talking out as properly. Testifying earlier than a Maine legislative committee this 12 months in help of a invoice that may restrict occupational PFAS publicity, Criswell stated, “We, as physicians, who are sworn to protect the health of our patients, must pay attention to the underlying causes of the illnesses we treat and stand up for policy solutions that reduce these causes.”
Even the place coverage modifications are instituted, the bodily and psychological toll of “forever chemicals” will lengthen far into the longer term. Criswell and different Maine medical doctors have noticed persistent stress amongst sufferers.
Nordell, the previous farmer, described his household’s contamination as “deeply, deeply jarring,” an ordeal that has at instances left him “unmoored from a sense of security.”
To assess the psychological well being penalties of PFAS publicity in rural residents, Criswell and Abby Fleisch, a pediatric endocrinologist on the MaineHealth Institute for Research, teamed up on a research. In its first section, winding up this summer season, they collected blood samples and detailed life-style data from 147 individuals.
Nordell, the Higginses, and different Central Maine residents sit on an advisory board for the research, a step Criswell stated was crucial to making sure that their analysis helps these most affected by PFAS.
“The urgency from the community is really needed,” she stated. “I don’t think I would be as fired up if my patients weren’t such good advocates.”
Criswell has confronted what she calls “cognitive dissonance,” caught between the deliberate tempo of peer-reviewed medical analysis and the fast wants of sufferers desirous to decrease their PFAS body burden. Initially she thought-about inviting residents to take part in a scientific trial to check therapies which might be thought-about secure and will assist cut back PFAS ranges within the physique, reminiscent of high-fiber diets and a drug designed to scale back ldl cholesterol known as cholestyramine. But the scientific trial course of might take years.
Criswell and Fleisch are as a substitute planning to provide a case series on PFAS blood-level modifications in sufferers taking cholestyramine. “We can validate the research results and share those,” Criswell stated, probably serving to different sufferers.
Alan Ducatman, an internist and occupational doctor who helped design the largest PFAS cohort study thus far, stated suppliers ought to convey that “there is no risk-benefit analysis” for any of the present therapies, though they’re typically well-known and low-risk.
“Some people want to be treated, and they should be allowed to be treated,” he stated, as a result of realizing they’ve excessive PFAS ranges of their our bodies “preys on them.”
