Sewage Sludge Fertilizer From Maryland? Virginians Say No Thanks.
In 2023, sewage plants in Maryland started to make a troubling discovery. Harmful “forever chemicals” were contaminating the state’s sewage, much of which is turned into fertilizer and spread on farmland.
To protect its food and drinking water, Maryland has started restricting the use of fertilizer made from sewage sludge. At the same time, a major sludge-fertilizer maker, Synagro, has been applying for permits to use more of it across the state border, on farms in Virginia.
A coalition of environmentalists, fishing groups and some farmers are fighting that effort. They say the contamination threatens to poison farmland and vulnerable waterways that feed the Potomac River.
These sewage sludge fertilizers “aren’t safe enough for farms in Maryland, so they’re coming to Virginia,” said Dean Naujoks of the Potomac Riverkeeper Network, which advocates for clean water. “That’s wrong.”
Virginia finds itself at the receiving end of a pattern that is emerging across the country as states scramble to address a growing farmland contamination crisis: States with weaker regulations are at risk of becoming dumping grounds for contaminated sludge.
In Virginia, Synagro, one of the nation’s leading providers of sludge for use as fertilizer, has sought permission to apply more sludge in rural Virginia, according to local filings. Synagro is controlled by a Goldman Sachs investment fund.
Kip Cleverley, the chief sustainability officer at Synagro, said in a statement that the fact that the fertilizer “may contain trace levels of PFAS does not mean that they are contaminated.” He said that Synagro continually adds new farms to its fertilizer program and that its decision to seek additional permits in Virginia was independent of any Maryland guidelines.
The fertilizer industry says more than 2 million dry tons of sewage sludge were used on 4.6 million acres of farmland in 2018. And it estimates that farmers have obtained permits to use sewage sludge on nearly 70 million acres, or about a fifth of all U.S. agricultural land.
But a growing body of research shows that this black sludge, also known as biosolids and made from sewage that flows from homes and factories, can contain heavy concentrations of harmful chemicals called per- and polyfluoroalkyl substances, or PFAS. Those chemicals are thought to increase the risk of some cancers and to cause birth defects and developmental delays in children.
For people in regions like Virginia’s Northern Neck, the “Garden of Virginia” that is the birthplace of George Washington, the threat feels doubly unfair: Much of the biosolids moving across state lines come from big industrial cities like Baltimore.
The contamination, locals fear, will wash off the farmland and into the region’s rivers and creeks, and will hurt the farmers and watermen who live side by side.
“The water just runs off from the farmland into the water,” said Lee Deihl, a seventh-generation waterman who owns the Northern Neck Oyster Company, as he maneuvered an oyster boat through a winding tributary of the Potomac. “And we get some pretty big rains this time of year.”
His concerns are not unfounded. New research published in the scientific journal Nature found that PFAS in sludge applied as fertilizer can contaminate both farms and surrounding rivers and streams.
“That stream might be the headwaters to your drinking water, further downstream, or the chemicals might be bioaccumulating in fish,” said Diana Oviedo Vargas, a researcher at the nonpartisan Stroud Water Research Center, who led the federally funded study. “There’s a lot we don’t know. But these contaminants are definitely reaching our surface water.”
It is a tricky problem. Fertilizer made from sewage sludge has benefits. The sludge is rich in nutrients. And spreading it on fields cuts down on the need to incinerate it or put it in landfills. It also reduces the use of synthetic fertilizers made from fossil fuels.
But the sludge can be contaminated with pathogens as well as chemicals like PFAS, research has shown. Synthetic PFAS chemicals are widely used in everyday items like nonstick cookware and stain-resistant carpets, and are linked to a range of illnesses.
The E.P.A. regulates some pathogens and heavy metals in sludge used as fertilizer, but it does not regulate PFAS. This year, for the first time, the E.P.A. warned of the health risks of PFAS in fertilizer made from sewage sludge. The Biden administration last year also set the first federal PFAS drinking water standards, saying there was virtually no safe level of the chemicals.
The lack of federal rules on PFAS in sludge has left states in charge, leading to a hodgepodge of regulations and the diversion of contaminated sludge to states with weaker regulations.
Maine banned the use of sludge fertilizer in 2022. Since then, some of its sewage sludge has been shipped out of state because local landfills can’t accommodate it, local officials have said.
Maryland temporarily halted new permits for the use of sludge as fertilizer. The Maryland Department of the Environment also ordered PFAS testing at sewage treatment plants across the state. It found contamination in the wastewater and sludge, even after the treatment process, and now has adopted guidelines, albeit voluntary, that say sludge with high levels of PFAS should be reported and disposed of.
In Virginia, the groups opposed to Maryland’s sewage imports are urging the state to start regulating PFAS in sludge.
But in the meantime, tens of thousands of tons of Maryland sludge are already heading to Virginia, according to data from Virginia. Biosolids from 22 wastewater treatment plants in Maryland have been approved for use as fertilizer in Virginia, and all 22 of those plants have reported PFAS contamination in their biosolids, according to an analysis by the Potomac Riverkeeper Network.
In Westmoreland, a rural county in the Northern Neck, Synagro has reported applying sludge from 16 wastewater treatment plants in Maryland, all from facilities that have reported PFAS contamination.
In December, Synagro applied for a permit expansion that would allow it to apply sludge on 2,000 additional acres of agricultural land in Westmoreland, more than doubling the total. After comments filed by local residents prompted a public hearing, Synagro withdrew its application, though it has told Virginia regulators it intends to reapply.
In neighboring Essex County, Synagro is seeking to apply sludge to an additional 6,000 acres, increasing the acreage by nearly a third, according to its permit application.
Mr. Cleverley of Synagro said the biosolids the company applied in Virginia met Maryland’s PFAS guidelines.
Irina Calos, spokeswoman for Virginia’s Department of Environmental Quality, said her state had yet to see a significant increase in the amount of Maryland biosolids being applied in Virginia. She said the state was still reviewing Synagro’s applications to increase its acreage in Virginia.
Ms. Calos also said Virginia was not aware of any Maryland biosolids with levels of PFAS higher than what was recommended in Maryland. Environmental groups have countered that it is difficult to verify.
Jay Apperson, a spokesman for Maryland, said the state’s guidelines and testing requirements aimed to protect public health while also supporting utilities and farmers.
Robb Hinton, a fourth-generation farmer, has grown corn, soy and other crops on Cedar Plains Farm in Heathsville, Va., southeast of Essex and Westmoreland counties, for 45 years. He fears farmers in the Northern Neck are being misled.
“When people are giving you something for free, or nearly free, it sounds attractive, and I don’t fault any farmer trying it,” he said. But they had to remember that “it’s these big cities that are bringing their waste to us,” he said.
“I didn’t know about PFAS until I was talking with my watermen friends,” he said. “I can’t understand how Virginia doesn’t test for this.”
Synagro has also been directly lobbying farmers and other local residents. At a presentation in March, a Synagro representative, together with a researcher from Virginia Tech, distributed data from a study that appeared to show that fields that had received sludge fertilizer had only a third of the PFAS levels of fields that had not, according to attendees as well as presentation slides reviewed by The New York Times.
Synagro said it could not provide the full study because the company was not involved in it. The Virginia Tech researcher named on the materials did not respond to requests for comment.
At a meeting of Virginia’s State Water Control Board in March, Bryant Thomas, the Virginia Department of Environmental Quality’s water division director, said the public had submitted 27 comments on Synagro’s plans to expand its use of sludge in Essex County. Of those comments, 26 expressed concerns over the effects of the sludge on public health and wildlife, including shellfish, he said.
The board subsequently requested that the agency study the issue further and report back.
“I think it’s interesting that Maryland is working on their rules and regulations, but then they’re sending their biosolids to us in Virginia,” Lou Ann Jessee-Wallace, the water board chairwoman, said in an interview. “We in Virginia are going to have to be on our toes to make sure that we are taking care of our water and our citizens.”
Experts say Maryland’s approach is a good first step. But even in Maryland, a bill that would have strengthened PFAS limits in biosolids failed at the last minute. And “we’re concerned about the patchwork of regulations among states,” said Jean Zhuang, a senior attorney at the Southern Environmental Law Center, an environmental nonprofit group. “The federal government needs to play a bigger role.”
President Biden had been set to propose a rule that would have limited how much PFAS industrial facilities could release in their wastewater. The Trump administration has pulled back that proposal, though recently said it could develop its own effluent limits.
Across the South, the center has already been pressing wastewater treatment plants to get local factories and other industrial facilities to clean up their wastewater before it reaches the treatment plant. That forces polluters to control pollution at the source, or even phase out the use of PFAS entirely, Ms. Zhuang said.
“If wastewater treatment plants acted, industries would be the ones paying for their own pollution,” she said, “and not the families and communities that rely on farms and pastures for their food, water, and livelihood.”
One recent evening, Michael Lightfoot, a waterman, went out to bring up a wire-mesh cage of oysters he cultivates in Jackson Creek, where he lives with his wife, Phyllis. After a nearly three-decade career with the federal government, he retired in 2012, and has been a full-time waterman since.
Mr. Lightfoot is part of an oyster cultivation boom in Virginia, which is now the East Coast’s biggest oyster producer and among the biggest producers in the nation. But his proximity to contaminated farms worries him, he said. “There is no farm field that doesn’t drain into our waterways,” he said.

Forest Service completed prescribed burns on 127,000 acres during shutdown, despite reduced workforce
During the government shutdown, the U.S. Forest Service completed prescribed burns on more than 127,000 acres, Forest Service Chief Tom Schultz announced in an internal memo welcoming back furloughed employees. During the same time frame in 2023 and 2024, the Forest Service completed a comparable amount of work, indicating the agency managed to take advantage of prime weather for burns even with a reduced workforce.
“Despite the disruption, we accomplished a great deal together,” the memo, first reported by the Hotshot Wake Up and verified by The Times, said. “We advanced timber sales that strengthen local economies, kept recreation sites open and safe for public enjoyment, and carried out critical wildfire response and active management work.”
By comparison, the Forest Service completed about 200,000 acres of prescribed burns in 2023 from Oct. 1 through Nov. 12 — the same span as the 2025 shutdown — and in 2024, it burned roughly 90,000 acres during that time frame, according to a Forest Service database that tracks hazardous fuel treatment work.
The latest contingency plan for the Forest Service — the largest federal firefighting entity in the country — called for continuing essential work during a shutdown, including responding to and suppressing wildfires.
The plan also involves furloughing roughly 30% of the service’s workforce, including those who oversee forest-use permit processing and public recreation, as well as researchers studying forest health and the timber market. Yet fuel treatment work, such as prescribed burning and mechanically thinning forests, is conducted by many of the same personnel responsible for putting out fires — the part of the workforce that avoided the furloughs.
That was important, given that significant fire activity across the West in 2024 inhibited the Forest Service from reducing wildfire risk on as many acres. So, this year, the Forest Service has been playing catch-up.
However, Grassroots Wildland Firefighters, a nonprofit representing current and former federal firefighters, found in October that Forest Service fuel management work in 2025 was down by 38% compared with recent years. The organization said that downturn was largely due to staff and resource cuts championed by President Trump’s cost-cutting team at the start of his second administration.
The Forest Service did not immediately respond to a request for comment.
California Gov. Gavin Newsom has challenged the federal government to match state investments in wildfire risk reduction work, and in July even sent the White House a draft executive order that Newsom said would accomplish exactly that.
In 2021, the state and U.S. Forest Service agreed to ramp up their yearly fuel treatment work in California to 500,000 acres each by 2025.
In 2023, the most recent year both state and federal data are available, the state reached 415,000 acres, and the Forest Service reached 311,000, according to a state dashboard. From 2021 to 2024, the state invested $4.3 billion to complete that work, whereas the Forest Service invested $3.1 billion.
This past weekend’s rain could mark an early start to prescribed-burn season in Southern California — home to a handful of national forests, including the Los Angeles and San Bernardino forests — as federal employees return to work until at least the end of January, when the agreed-upon funding is set to expire.
“I’m profoundly grateful to welcome our furloughed employees back as the government reopens,” Schultz said in the memo. “I look forward to getting the entire team back together to continue and build upon the work that we’ve begun this new fiscal year.”

CDC warns of dramatic rise in dangerous drug-resistant bacteria. How you can protect yourself
Infection rates are soaring in the United States due to a menacing bacteria that are resistant “to some of the strongest antibiotics available,” prompting infectious-disease experts to warn about the difficulty of responding to the surge.
The Centers for Disease Control and Prevention warned in a report this week that between 2019 and 2023, bacterial infections caused by a “super bug” bacteria dubbed NDM-producing carbapenem-resistant Enterobacterales (NDM-CRE) surged by more than 460% in the U.S.
The NDM-CRE is a type of bacteria with a special gene that can break down powerful antibiotics rendering most drug treatments ineffective, said Shruti Gohil, associate professor of infectious diseases at UC Irvine School of Medicine.
“This makes these ‘superbug’ bacteria very hard to treat because they’re resistant to some of the strongest antibiotics we have,” Gohil said.
The CDC’s findings, originally published in a 2022 report, noted that there were approximately 12,700 infections and 1,100 deaths in the U.S. in 2020 due to this drug-resistant bacteria.
The public health agency did not determine the exact reason for the surge; however, there is an association involving the use of antibiotics to treat COVID-19 patients in the beginning of the pandemic, said Neha Nanda, medical director of antimicrobial stewardship with USC’s Keck Medicine.
Public health officials warn that NDM-CRE has not historically been common in the U.S., so healthcare providers might not suspect it when treating patients with bacteria-related infections.
The rise of the bacteria also “threatens to increase NDM-CRE-related infections and deaths,” according to the CDC.
This is the second report the CDC released that highlighted a rise in bacteria-related cases, the most recent was published in June and focused on cases in New York City between 2019 and 2024.
Available treatment for NDM-CRE?
Experts say people with NDM-CRE bacteria won’t have any symptoms unless they develop an infection. Once they develop an infection, the symptoms will vary. NDM-CRE can cause such ailments as pneumonia, bloodstream infections, urinary tract infections and wound infections.
Some symptoms can include fever, chills with cough, shortness of breath if the bacteria infect the lung, and pain or blood when urinating if the bladder/kidneys are infected.
Since the bacteria are resistant to most antibiotics, treatment options are severely limited, leading to slower recovery and higher risk of serious complications or death, Gohil said.
Another reason health officials are concerned is because the bacteria can spread to others and survive on contaminated surfaces.
Doctors can test for NDM-CRE, but most people do not need to be tested unless they are at higher risk for having it, according to experts.
Those at risk are people who have been “in a hospital (especially in another country), had repeated antibiotics, hospital stays, or invasive medical procedures, or if you’re sick and been in contact with someone known to have NDM-CRE,” Gohil said.
Testing for the bacteria is also difficult because many hospitals and clinics do not have the tools to rapidly detect it in patients even when the patient is not sick.
How to protect yourself against NDM-CRE
NDM-CRE is caused by overuse of powerful antibiotics.
“I think this may be an opportunity for us to change the narrative where all patients typically want antibiotics,” Nanda said.
Nanda advises patients who are being prescribed with antibiotics to ask their healthcare provider:
- Why they’re getting prescribed the antibiotics? Why is it necessary?
- Ask about your options. Make sure you’ve exhausted all other treatments options before going straight to antibiotics.
“If you need it, you need it, but then be judicious about it,” she said.
Because NDM-CRE infections happen to people who are very sick, patients in hospitals or in long-term care, experts recommend that patients, healthcare staff and visitors in these settings wash their hands and avoid contact with dirty surfaces.

Trump says research links Tylenol and autism; scientists say their paper is being misinterpreted
During this week’s White House press conference in which President Trump named the over-the-counter drug Tylenol as a possible cause of rising autism rates, he did not mince words, urging pregnant women to “fight like hell” not to take it.
But outside those remarks in the Roosevelt Room — during which Trump himself acknowledged “I’m not so careful with what I say” — the discussion on the common fever and pain reliever’s role during pregnancy is a lot more nuanced.
What the research on Tylenol use during pregnancy actually says
Physicians, researchers on the very studies cited in support of Trump’s position and even other members of the president’s administration are largely united on a few key facts: untreated fevers in pregnancy pose real risks to the fetus, acetaminophen (Tylenol’s active ingredient) remains the safest medication to treat them and any pregnant person seeking advice on the issue should consult their doctor.
“All that we should be asking of the medical profession [is] to actually weigh the risks and benefits for the women, with the women, and be cautious about chronic use of pain medications,” said Dr. Beate Ritz, a UCLA professor of epidemiology who co-authored a paper published last month that the White House cited as evidence for the link between Tylenol and autism.
Ritz said it has been misinterpreted.
The conclusion of the paper, which reviewed existing studies on the topic, was that the association between acetaminophen use in pregnancy and later diagnoses of neurodevelopmental disorders in kids was strong enough to merit doctors’ consideration when determining how to treat fever or pain in pregnancy. The group did not determine a causal relationship between the drug and autism, or suggest barring the drug altogether, she said.
“Looking at all of these studies, yes, there is a risk,” Ritz said. “It’s not very big, but it’s there, but the risk increases are more seen in regular users of Tylenol. This is not a woman who has a fever and takes three Tylenols.”
“There is always a weighing of the risks and the benefits, and fever in women is no good either. … Not having to take any pain medications when you are in severe pain or in chronic pain is also very cruel,” she said. “We all should have an interest in helping out here, making the right decisions without blaming the victim and putting it all on the individual woman.”
Her co-author, University of Massachusetts epidemiologist Ann Bauer, has made similar statements.
“What we recommend is judicious use — the lowest effective dose [for] the shortest duration of time under medical guidance and supervision, tailored to the individual,” Bauer told the news outlet Politico.
The administration’s confusing recommendations
Ultimately, that’s what the administration is recommending as well.
The letter that U.S. Food and Drug Administrator Dr. Marty Makary sent to physicians this week made clear that “a causal relationship” between autism and acetaminophen “has not been established and there are contrary studies in the scientific literature.”
It went on to recommend that clinicians consider limiting their use of acetaminophen for routine low-grade fevers during pregnancy, while noting that medical advice “should also be balanced with the fact that acetaminophen is the safest over-the-counter alternative in pregnancy among all analgesics and antipyretics.” (An analgesic is a pain reliever; an antipyretic reduces fever.)
Untreated fevers during pregnancy are associated with higher rates of birth defects, particularly those of the heart, brain and spinal cord; premature birth; low birth weight; neurodevelopmental disorders including autism; and fetal death, said Dr. E. Nicole Teal, an assistant professor of maternal-fetal medicine at UC San Diego.
“The FDA’s letter, while significantly more nuanced than the president’s comments on the issue, still gives too much weight to findings from poorly designed studies,” she said.
She said she will continue to prescribe acetaminophen to pregnant patients who need to treat fevers or severe pain, as it has the fewest known risks in pregnancy.
Are there other pain-relief and fever-reducing drugs that can be used during pregnancy?
Nonsteroidal anti-inflammatory drugs like ibuprofen (often sold as Advil) or naproxen (often sold as Aleve) are linked to problems with blood vessel and kidney development, as well as oligohydramnios, a condition in which there isn’t enough amniotic fluid to support a healthy pregnancy. Aspirin raises the risk of bleeding complications, and narcotics — which can relieve pain but not fever — pose addiction risks for the mother and infant alike, Teal said.
She referred to a statement from the American College of Obstetricians and Gynecologists noting that two decades of research on the question had failed to find a causal relationship between acetaminophen and autism.
“Acetaminophen is one of the few options available to pregnant patients to treat pain and fever, which can be harmful to pregnant people when left untreated,” American College of Obstetricians and Gynecologists president Dr. Steven J. Fleischman said in the statement.
The group also noted that reviews in 2015 and 2017 from the FDA and the Society for Maternal-Fetal Medicine respectively found no risks associated with appropriate usage of the drug in pregnancy.
How to navigate government communications around Tylenol use
Nonetheless, the mixed messaging from the Trump administration about Tylenol seems likely to continue.
The Department of Health and Human Services this week reposted a 2017 tweet from the Tylenol brand’s account that said, “We actually don’t recommend using any of our products while pregnant.”
A spokesperson for Kenvue, the company that owns Tylenol, said the post was taken out of context and incomplete.
“Consistent with regulations, our label states clearly ‘if pregnant or breast-feeding, ask a health professional before use,’ ” Melissa Witt said in an email. “We do not make recommendations on taking any medications in pregnancy because that is the job of a healthcare provider.”
Vice President JD Vance offered similar guidance this week.
“My guidance to pregnant women would be very simple, which is follow your doctor. Right?” Vance said in an interview with the outlet NewsNation after Trump’s press conference. “Talk to your doctor about these things.”
