Environmental advocates are waiting for results from legislation passed last year, regulating the use of industrial sludge from flowing into waterways like the Chesapeake Bay.

Before laws were passed, the state had limited regulations dealing with the handling and use of industrial sludge, often made up of leftovers from meat processing facilities, which are then used as farmland fertilizers. Mishandling or overuse of the fertilizers would lead to the contamination of groundwater and flow into waterways.

Evan Isaacson, senior attorney for the Chesapeake Legal Alliance, said it was even common for neighboring states with tighter regulations on industrial sludge to transport it to Maryland for dumping.

"We had essentially become the dumping ground for industrial sludge," Isaacson recounted. "It was just an opportunistic business opportunity, I guess, for that industry to evade existing regulatory frameworks in their home states and send it to Maryland."

A 2023 study by the University of Maryland found more than half of industrial sludge land applied in Maryland came from other states. The Maryland Department of Agriculture oversees the year-old regulations governing industrial sludge.

Isaacson argued the department could change regulations to promote more transparency or put out a report on industrial sludge. He pointed out some issues, like farm privacy, means the department's regulations are not always created with as much transparency in mind, like with the Maryland Department of the Environment. Isaacson hopes other states without regulations will introduce their own standards to keep industrial sludge from being dumped in neighboring states.

"Once this regulatory program is up and running properly, it fixes that problem," Isaacson emphasized. "At the very least, we're hoping that we no longer become the regional dumping ground and that those sources in Delaware and Virginia keep their material in Delaware and Virginia."

The neighboring states of Pennsylvania and West Virginia currently have no regulations on the use and dumping of industrial sludge.

The Washington State Pollution Control Hearings Board is ordering state officials to rewrite pollution discharge permit regulations for concentrated animal feeding operations, or CAFOs.

The order was issued after a challenge from community and conservation groups, complaining that previous regulations violated state and federal law. The complaint alleged that the state failed to control the discharge of excess nutrients, bacteria and other pollutants from dairy factory farms.

Tyler Lobdell, a staff attorney for Food & Water Watch, said the state must better protect its water, wildlife and communities.

"The state of Washington hasn't been requiring what are called nutrient management plans or the newer pollution prevention plans to be robustly developed by every CAFO," he said, "and they haven't required those plans to be available to the public to make sure they're actually doing what they're supposed to do."

The ruling ordered the state Department of Ecology to require CAFOs to control pollution from animal waste runoff. CAFOs are industrial farming and dairy operations that can generate substantial amounts of animal waste, which must be appropriately managed to prevent water and air pollution.

Lobdell said it's essential that the order stipulates the public's right to review and comment on all regulations before they are issued, noting that the state has a poor track record of protecting waterways from nitrate pollution. He said having the Environmental Protection Agency involved strengthens the process.

"The state of Washington issues a single, combined permit that covers both the Federal Clean Water Act, which is authority delegated by U.S. EPA to Department of Ecology," he said, "but it also covers Washington state law, which is more expansive."

Several conservation groups, including the Waterkeeper Alliance, the Center for Food Safety, Friends of Teppenish Creek and the Sierra Club, participated in filing the complaint. The appellants were represented by the Western Environmental Law Center.

Johnson County's long saga with PFAS started in 2022, with an influx of calls to Detective Dana Ames, an environmental crimes investigator for the Texas county located just south of Fort Worth. The calls sounded like "desperate pleas for help from all over the state," Ames says, as residents were suddenly seeing dead animals. "We're getting report after report after report," she recounts, with people telling her, "Yeah, they applied this stuff across the street from us, and our animals are dead." More than two years later, county officials declared a state of disaster, as testing pointed to high levels of PFAS in the county's farmland. PFAS stands for per- and polyfluoroalkyl substances, also dubbed "forever chemicals" because they require much longer spans of time to break down in soils. But in Johnson county, officials attributed these high levels of PFAS to a form of processed waste called biosolids - also known as sewage sludge - that were applied to farms as fertilizer to boost crop fertility.

More than two million dry tons of biosolids were applied to U.S. farmland in 2018, according to a report from a biosolids industry group. Biosolids are sourced from treated sewage - waste flowing from homes and factories, everything from basic manufacturing facilities to slaughterhouse operations. In a press release, county officials characterized the test results as an "immediate threat" - to farms, drinking water and public health.

The process works like this: first, wastewater treatment plants filter out the water from sewage, Christopher Higgins, an environmental chemist at the Colorado School of Mines, tells Sentient. The solids left behind can then be processed and turned into fertilizer. One problem, however, is that so-called forever chemicals do not break down during that process, which means these chemicals travel into soils along with the biosolids.

Johnson County is now at the center of two lawsuits: local farmers are suing the biofertilizer company Synagro Technologies, and, along with the county itself, are also suing the U.S. Environmental Protection Agency.

Biosolids, Explained

Nearly 4.5 billion pounds of sludge were used in the United States in 2023 alone, applied to farmland or used in compost for gardens and landscaping. The EPA has long promoted agricultural use of sewage sludge as an environmentally friendly way to reuse municipal waste.

Last year, a New York Times investigation revealed that even though the EPA was aware of the potential risks of biosolids since at least 2003, the agency continued to encourage the practice.

The strategy of applying excess waste - whether from livestock operations or city wastewater - is a common one on farms. Fertilizer, whether synthetic or manure, is used to boost yields and enhance crop fertility. But there are other consequences, as the waste and its contaminants don't tend to stay put. In Iowa, for example, fertilizer is so over-applied or misapplied that it ends up contaminating nearby waterways. Manure storage tanks can leak or break down. Dangerous pathogens like E. coli linked to food outbreaks have been traced back to dust particles from manure.

In early January of this year, the EPA released a draft risk assessment that warned of the PFAS contamination that can occur from sewage sludge used as fertilizer. The assessment found that around 31 percent of sewage sludge was used on farms. Any land that has had biosolids applied will have some amount of PFAS, says Higgins, but not necessarily at the levels seen in Johnson County.

Johnson County officials who spoke with Sentient expressed hope the area would receive federal assistance. Yet the Trump administration's moves to slash EPA programs and aid provided by the Federal Emergency Management Agency (FEMA) could complicate the response, though so far EPA regulators working on biosolids risk do appear to still be employed by the agency.

Other advocates are not so confident about future funding, in part because Texas governor Greg Abbott is a staunch supporter of the president. "I don't have a lot of faith that it will get approved by the governor, but I hope it will," says Kyla Bennett, the director of science policy with Public Employees for Environmental Responsibility (PEER) and a former EPA attorney. "I guess we're just going to have to wait and see."

'Shocking to the Conscience'

When Detective Ames first received a complaint in 2022, it was from a rancher seeing fertilizer that had been smoking on a neighboring farm for days. "He was just complaining that it was horrible. He couldn't breathe. It smelled bad," Ames tells Sentient. The smoke had caused the valley where the farmer lived to fill up with smoke.

Ames drove out to the farm and found 12 to 15 large piles of smoking biosolids. She then brought what she learned to her boss, Constable Troy Fuller, and County Commissioner Larry Woolley. From there, Ames launched an investigation that involved calls with scientists, environmentalists and EPA whistleblowers. "It was shocking to the conscience, honestly, what all I learned," she says.

"We tested the well water. We tested soil, we tested the pond water. From animals that were dying, we tested their livers. We tested fish in the ponds," she says. "We had PFAS contamination in everything."

A stillborn calf's liver had over 610,00 parts per trillion (ppt) of PFAS. Fish had 57,000 ppt of PFAS. They found PFAS in a property's well water too, according to Ames.

The levels of PFAS found in Johnson County were unusual - "really, really high," confirms Higgins, a researcher who was not involved in the investigation but reviewed the public test results. He says there could be two reasons for that. Either the farmers applied more biosolids than is typical, or the levels in the sludge were just unusually high to begin with. "It's more likely the latter," he says.

Ames feels an obligation to uncover what happened. "I think we owe our citizens to know what's happening here, to listen, to believe them when they tell us there's something wrong, even though we can't put our finger on it," she recalls telling the commissioners. "And we need to test, because if what I'm reading is accurate and what I'm being told is accurate, we may have a very dangerous contaminant that has been land applied, and that could have a lot of far-reaching consequences."

County and Watchdog Groups Pursue Lawsuits and Legislation

"The more we allow these biosolids to spread, and the more we allow this to continue without cleaning it up, or at least attempting to clean it up, is just sentencing the farmers of Texas to decades of unusable land, inedible meat, milk, fish, dairy," says Bennett, who works for the watchdog group PEER.

PEER is representing Johnson County and other plaintiffs in their case against the EPA, which aims to compel the agency to address the PFAS and biosolids under the Clean Water Act. "It's rendering the farmland useless, and harming the people themselves."

Christopher Boedeker, the county judge who issued the declaration, tells Sentient that one of the primary purposes of the declaration is to work with the state government to pass legislation that addresses and stops the contamination. "We've done all of this out in the daylight with the intent of shining a spotlight on what's going on here," Boedeker says.

"And then the other part of it is, of course, making our citizens who have been impacted eligible for federal aid." The affected farmers in Johnson County have kept their cattle, but are not selling them, and county officials would like to see the farmers compensated.

"I've had, strangely enough, a few negative interactions, and those have all been questions of, well, why didn't you all do more sooner?" says Boedeker. "I feel like that's in some ways validating, that people believe we're doing the right thing here. I think we're doing the right thing here."

The EPA told Sentient it does not comment on ongoing litigation.

"It's really important to recognize that this is not a partisan issue," says Laura Dumais, legal counsel at PEER. "No one wants toxic chemicals in their food. No one wants farmers to be poisoned. Johnson County is a rural, conservative county, and everyone's reaction is: how come the EPA hasn't regulated this."

How to address PFAS under current regulations can quickly get complicated, says Bennett, who is the director of science policy for PEER. "We don't know how widespread the contamination is. We don't know how much it will cost to try to remediate it, or whether it can be remediated. There are a lot of unanswered questions."

Texas lawmaker Helen Kerwin has already filed a bill to require biosolids to be tested for PFAS levels. Other states have already taken steps to restrict their use. Michigan, California and Wisconsin require wastewater treatment plans to test biosolids for PFAS, while Connecticut and Maine have banned the use of biosolids on farmland all together.

If anything, says Higgins, the situation in Johnson County "indicates we need more testing. As an environmental chemist, I would not be disappointed if every single soil farm that had received biosolids over the last 50 years was tested. I think that's not an unreasonable ask."

Ames put it more bluntly: "Stop using our [agricultural] land as the city's toilet."

One of many federal agencies facing cuts by the Trump administration's Department of Government Efficiency is the National Oceanic and Atmospheric Administration. Scientists said it will threaten Americans' safety, especially in states with extreme weather events, including Montana.

NOAA employees are bracing for expected staffing cuts of up to 20%, or more than 1,000 jobs. Among other roles, NOAA's National Weather Service provides open-source weather data the majority of U.S. forecasters use, including for warnings and advisories.

Bernadette Woods Placky, chief meteorologist and vice president of engagement for Climate Central, said NOAA provides critical weather data.

"Because of NOAA data, we know when to evacuate ahead of storms, fires," Woods Placky explained. "We know when not to evacuate, which is also really critical because that saves a lot of money and a lot of time."

Other conditions NOAA data helps Montanans understand include avalanches, floods, high winds, air quality, red-flag warnings and extreme heat. Woods Placky added beyond short-term predictions, NOAA data helps farmers understand what to plant and when to harvest, especially as crop hardiness zones shift due to climate change.

NOAA's data on storm events and climate change dates back to 1950 and goes beyond U.S. borders. Woods Placky pointed out unstable governments can interrupt data gathering.

"When you get that gap in the data, it invalidates the long-term data sets," Woods Placky stressed. "You can't carry it with the same weight to tease out longer-term trends to keep people safe and prepared on longer-term shifts that we're seeing."

She added global groups use NOAA's data, including the Intergovernmental Panel on Climate Change and the United Nations.

David Dickson, TV engagement coordinator for the nonprofit Covering Climate Now, said while some have argued services NOAA offers could be privatized, the sentiment shows a misunderstanding.

"To argue against NOAA not being useful because we have private companies offering weather apps would be to argue against farmers because we have grocery stores," Dickson emphasized. "It really does fund the invisible backbone of virtually everything we consume."
