Maine adopts tougher limits on PFAS in drinking water
The Maine Center for Disease Control and Prevention has lowered the state limit on forever chemicals, or PFAS, in drinking water to align with rigorous federal standards established by the Biden administration.
The change reduces the maximum amount of the two most harmful forever chemicals to four parts per trillion (ppt) — roughly four drops in 20 Olympic-sized swimming pools — and no more than 10 ppt, for three others combined.
The new rule, adopted in December, will be rolled out in phases, from monitoring by 2027 to initial enforcement in 2028. When in full effect, Maine’s 1,900 public drinking water systems could face fines of up to $2,000 per day for exceeding the maximum contaminant limits.
“The (Department of Health and Human Services) has determined that these new requirements are necessary to protect public health,” it wrote in a rule summary. “The department will work with stakeholders to provide technical assistance and guidance where needed.”
Maine’s old limit was 20 ppt for the combined sum of six forever chemicals. The two most harmful, PFOA and PFOS, are now capped at four ppt each, which is a sharp decrease because they account for the bulk of most forever chemical readings in Maine.
Systems have until April 2029 to comply, which could require treating water, drilling new wells or hooking up to a clean water supply. Until then, Maine will use its 20 ppt limit to “cover the gap,” said DHHS spokeswoman Lindsay Hammes.
Forever chemicals have been used since the 1940s in consumer products and industry, including in nonstick pans, food packaging and firefighting foam. Even trace amounts are deemed harmful, linked to a host of health problems that range from immune deficiency to certain cancers.
State public health officials estimate it could cost $50 million to bring Maine’s public drinking water systems into full compliance with the new standard. The state plans to tap the federal safe drinking water revolving loan fund to cover those costs.
Maintaining each system could cost between $1,000 to $100,000 a year, public health officials predict.
An analysis of state data from 2023 by Defend Our Health, a Portland environmental nonprofit, determined that one in 10 Mainers — roughly 134,035 people — drinks from a public water supply that exceeds the limit Maine just adopted, including in Augusta, Sanford and Waterville.
The group’s data showed that more than 14,000 students and staff at 60 Maine schools, day cares, and colleges are drinking water that was below Maine’s old limit but are above its new limit, like Lake Region High School in Naples or Marshwood Middle School in Eliot.
The U.S. Environmental Protection Agency adopted its protective PFAS limits in April 2024. It said the limit would prevent thousands of premature deaths, serious adult illnesses, and immune and developmental impacts to children.
Private well owners remain responsible for ensuring their water is safe to drink. The quality and safety of private domestic wells are not regulated by the federal government, nor by most state laws. About half of Maine’s residents gets their drinking water from a private well.
Two of the four forever chemicals that had been regulated under the old state rule, PFDA and PFHpA, will not be regulated under the new rule. They are used in food packaging and stain-resistant coatings on rugs and furniture.
Advocates wanted these to count toward the new state limit, but officials say it’s not necessary; they only occur when there is too much PFOA or PFOS anyway. The state will still require the systems to monitor for these chemicals even though they won’t count toward the cap.
The new rule will also require Maine water systems to regulate two new forever chemicals: GenX and PFBS. These chemicals were created to replace PFOA and PFOS but have been found to pose similar health concerns.
Previously, the EPA had advised but not required a drinking water limit of 70 ppt. Many of Maine’s other PFAS advisory levels for milk, eggs, beef, crops, hay, fish or game are based on this old advisory.
State officials said they will use the new EPA standard, and the science supporting it, to inform Maine’s PFAS standards in other substances, but said it would happen over time, and that no one should expect Maine’s milk, beef and fish consumption advisories to change soon.
Maine has identified more than 600 residential wells near former sludge fields, military bases and industrial sites that test above Maine’s old PFAS limit, and that amount is likely to double under the new standard.
The Maine Department of Environmental Protection could not be reached for an interview about how the new limit will be used when deciding who among those living on sludge-impacted land will have their water remediation costs covered by the state.

Who is raising the most money in the Maine governor’s race?
(Joe Phelan/Staff Photographer)
Candidates vying to become Maine’s next governor have until midnight Tuesday to file campaign finance reports for the first quarter of the year.
The reports will show who is best positioned to control the message in the final month-plus until the primaries. But fundraising success doesn’t always guarantee a win at the ballot box.
The reports come as a growing number of leading candidates are taking to the airwaves a head of the June 9 primaries. Five Democrats and seven Republicans are vying to replace Gov. Janet Mills, who is term limited.
As of Tuesday, Republican Jonathan Bush topped all candidates in broadcast, cable and digital advertising, having booked nearly $1.5 million in ads through the primary, the political spending tracker AdImpact said.
But Republican Garrett Mason is benefitting from about $3 million in spending by Restoration of America PAC, which is running ads targeting Gov. Janet Mills and tying Mason to President Donald Trump.
Other Republican candidates running ads are Bobby Charles ($63,000), Owen McCarthy ($43,660) and Ben Midgely ($55,000.)
Hannah Pingree tops the Democratic slate with about $564,000 in ad spending, followed by Nirav Shah ($493,000), Shenna Bellows ($462,700) and Angus King III ($299,000.)
As of Tuesday afternoon, fundraising totals were only trickling in. Public access to those reports was hampered because the Maine Commission on Governmental Ethics & Election Practices is building a new website, and glitches made some reports unviewable.
This story will be updated when more reports are filed. As of Tuesday afternoon:
- Republican Jonathan Bush reported raising about $845,000 in the first quarter, but 60% of that, $500,000, was a personal loan to his own campaign. His totals were not yet available through the new website, but his quarterly fundraising and spending was provided by ethics staff.
- Republican Robert Wessels was the only other active candidate that had filed. He raised nearly $11,600 for the quarter and has about $13,540 in cash.
This is a developing story.

Moldy Maine weed is being treating with radiation
Maine marijuana growers are increasingly using radiation and other methods to remove contaminants from their products, a process consumers are likely in the dark about.
Despite a state policy requiring remediated products to be labeled as such, Maine’s Office of Cannabis Policy is not enforcing that rule.
In response to a complaint by a dispensary owner in late February, deputy director of operations Vern Malloch acknowledged, “we are not requiring labeling of remediated or treated product,” according to records obtained through a media request.
“We plan to issue guidance on this in the near future,” Malloch wrote.
Office of Cannabis Policy Director John Hudak also told lawmakers last year that the agency hasn’t enforced remediation labeling requirements since at least November 2024.
“The Office began receiving pushback from cannabis cultivators who did not want to label their cannabis if they ‘treated’ their cannabis with radiation or ozone prior to submitting the cannabis for mandatory testing,” Hudak wrote in testimony last year.
A spokesperson for the agency declined to answer specific questions Monday, but confirmed the agency stopped enforcing the rule after some growers raised concerns over the “misleading impact” that labeling treated cannabis has on consumers.
“Requiring label disclosure of the use of irradiation or ozone treatment implies a consumer risk that is not scientifically supported and is potentially misleading in its implication about potential harm from exposure,” Alexis Soucy, OCP’s director of media relations, wrote in an email.
Over the last couple years, several marijuana products have been subjected to recall because of high levels of mold, yeast and other contaminants. Unsafe levels of mold in cannabis can cause flu-like symptoms, including respiratory issues, sinus infections, headaches and dizziness.
But rather than tossing their product, growers can turn to a process called irradiation, often involving gamma rays or X-rays, to remove contaminants.
Supporters say it’s a safe way to reduce waste and prolong shelf lives. Mold and yeast grow naturally just about everywhere and many species are benign. Standard cannabis mold testing does not differentiate between harmful and harmless microbes.
Opponents, however, argue there isn’t enough research about remediating cannabis to say whether it’s safe or not. There is not much data on whether the various types of remediation are effective at killing microbes or are safe for consumers, most of whom don’t know about the practice.
“It’s a complex topic without many answers,” said Yasha Kahn, who co-founded MCR Labs, one of four licensed cannabis testing facilities in Maine. “Hopefully, the rescheduling can lead to more research.”
The federal government moved last week to reclassify cannabis from a Schedule I to Schedule III drug. Decades-long restrictions on cannabis research will be lifted, which acting Attorney General Todd Blanche said will allow for studies into “marijuana’s safety and efficacy.”
Kahn, who operates several testing labs throughout New England, said irradiating cannabis has become increasingly prevalent in legal markets across the country and the world. It’s still debated whether irradiation works as well as it’s supposed to, he said.
‘THIS IS A FAIRLY NEW PROCESS’
There are numerous kinds of cannabis remediation, each with its own pros and cons. Growers most commonly use X-rays, gamma radiation or ozone gas to remove mold and microbes.
Radiation does not kill all the mold, yeast and other microbes present in cannabis outright, Kahn said. Certain species of mold, like harmful mycotoxins, can often survive remediation. Others can remain dormant for months following the procedure.
“Irradiation gets rid of mold’s ability to procreate, and not necessarily permanently,” he said. “You can take that same product and test it again, months from then, and there’s going to be mold growth.”
Some in the industry, like organic marijuana farmer Lizzy Hayes in Mercer, fear that having the option to remediate cannabis removes the incentive to grow clean cannabis. If you can simply use radiation to eliminate mold from harvested crops, she said, why would you put effort into growing mold-free products?
Part of the blame, according to Hayes, lies at the feet of Maine’s recreational cannabis testing regime. Unlike the state’s medical marijuana market, batches of recreational cannabis products must be tested for contaminants like mold, yeast and heavy metals before they can be put on a dispensary shelf.
But since the mold test only detects the presence of mold, not whether it’s harmful, Hayes said many growers save themselves the trouble and irradiate their cannabis by default rather than risking a failed test.
“When you have a regulatory system that incentivizes irradiation, it’s also making it so that customers don’t have access to as high quality of a product,” she said.
Some in the industry disagree. A bill was proposed last year to codify requirements around labeling treated cannabis and inspecting remediation equipment. It was ultimately defeated after many Maine cannabis growers testified in opposition to the bill.
“Radiation and ozone treatment methods are well-established, scientifically validated technologies commonly used in industries far beyond cannabis,” wrote Jacob Racioppi, owner of Goose River Cannabis in Unity. “In fact, they are standard in the food industry.”
Joel Pepin, co-founder of JAR Cannabis Company, owns and operates one of about a dozen X-ray machines in Maine’s cannabis industry. He estimated that about half of Maine’s recreational cannabis has been treated by similar methods. It would be overkill, he said, to require all of that product to be labeled over scientifically unfounded concerns.
“If we apply this same logic to other industries in Maine, then why doesn’t this bill also require dental patients to wear a shirt that says, ‘treated by X-ray’ after leaving the dental office?” Pepin testified.
Neither Racioppi nor Pepin responded to requests for an interview.
Lorri Maling, laboratory director at cannabis testing facility Nelson Analytical, seconded Pepin that remediating cannabis is “more in use now than it was a few years ago.”
While some opponents of irradiation claim the process reduces THC content and eliminates terpenes — the chemicals that give different cannabis strains unique scents and effects — Maling said there’s no data to back that up. Nor is there much data to back up many other conclusions about the effects of irradiating cannabis.
Most of the studies on the effects of irradiation have been on fruits and vegetables, she said, which have not shown any negative effects — though there’s no guarantee that any remediation method will kill all bacteria.
“This is a fairly new process for cannabis,” Maling wrote in an email. “I really cannot say that it is safe or unsafe for cannabis as there really is not enough data on this.”
