A new report from environmental watchdog group Food & Water Watch suggests that almost 2 million fish were killed from manure spills in Iowa between 2013 and 2023. The 179 spills occurred throughout the state, with a major hotspot for spills in the northwest corner of the state. Earlier this year, the group reported that Iowa factory farms produce more waste than any other state, at 109 billion pounds of manure annually, based on U.S. Department of Agriculture data.

The report and accompanying map, released on Dec. 9, designated over 700 segments of Iowa water as “impaired” — not meeting the standards necessary to support aquatic life, public water supplies or recreation. Details include where in the state spills occur, who owns the operation and if they are repeat offenders.

Manure spills in the state of Iowa have contributed to what environmental advocacy groups call a water quality crisis. In the capital city of Des Moines, the local water supply has one of the world’s largest nitrate removal facilities. Nitrate is the resulting chemical of manure that is not absorbed by the soil or crops. Due to high levels of nitrate in water, which can cause blue baby syndrome in children and colon cancer in adults, the Des Moines Water Works has to run its nitrate removal system more frequently as the situation worsens — at a cost of anywhere from $10,000 to $16,000 per day, which falls entirely on utility customers.

“When you think about the nature of what they’re spilling and the quantities of what they’re spilling, it’s the difference between life and death, and people are being strapped down with medical debt and suffering in a prolonged way,” Food & Water Watch Iowa Organizer Michaelyn Mankel tells Sentient.

According to the report, the Iowa Department of Natural Resources fined 171 of the 179 offenders at $635,808 over the ten-year period it studied. That’s less than half of what Des Moines Water Works spent on its nitrate removal system in 2015, at $1.4 million. There are gaps in the state reporting as well. The total volume of the spills is difficult to determine because most reports do not contain information on how much manure is spilled. And in those that do note volume, the range is anywhere from 500 to 1 million gallons.

“The fines that the DNR has leveled against these companies do not represent restitution for the damage that they’re causing to Iowa,” Mankel says. “They also don’t represent a real demand that these corporations change the way that they’re doing business.”

In 2024 alone, the Iowa Department of Natural Resources documented 13 fish kill events, one of which regulators directly tied to animal waste. This one “anthropogenic” spill in northwest Iowa — caused by dairy manure land-applied runoff —killed anywhere from 100,001-500,000 fish.

Many concentrated animal feeding operations operate without the proper discharge permits, rendering their spills more difficult to track. In October, the Ninth Circuit Court of Appeals struck down a petition from 13 groups — including Food & Water Watch — calling for stricter regulation and enforcement of the Clean Water Act. Today, Food & Water Watch is calling for a “Clean Water for Iowa Act” to be passed in the state legislature. The act would require all medium and large-scale concentrated animal feeding operations to get National Pollutant Discharge Elimination System permits.

This report and map are released in the midst of a health crisis in the Midwest, which some observers and critics argue is tied to, or exacerbated by, large-scale industrialized agriculture. Mankel points to cancer incidence in the state of Iowa; it’s the only state in the country with rising cancer rates (though other factors, like obesity and alcoholism rates may play a role).

“We’re paying for it,” Mankel says. “I really want Iowans to understand that these problems are a policy choice, and that we are being burdened with paying the true cost of massive profits that these corporations are reaping from our state, and that’s a very intentional choice on behalf of lawmakers.”

Environmental groups say Oregon's new groundwater law, meant to curb pollution, has been diluted to the point they can no longer support it.

Industrial agriculture has contaminated parts of Eastern Oregon's groundwater with nitrates from fertilizers and manure, putting residents, many of whom rely on wells for drinking water, at risk.

Kaleb Lay, director of policy and research for the group Oregon Rural Action, said earlier bill versions would have protected residents and held polluters accountable.

"Unfortunately, as the legislative session went on, we saw industry groups and big ag groups get more and more heavily involved," Lay pointed out. "We really saw the governor concede many of the really important points in this bill."

Nitrates are increasingly linked to cancer, miscarriages and birth defects. Gov. Tina Kotek said the new bill gives state agencies more authority to intervene in Oregon's contaminated groundwater areas.

Jim Klipfel moved to Boardman six years ago and discovered his well was contaminated with nitrates after a neighbor warned him not to drink from the hose. Now, he relies on delivered water as officials work on connecting residents to city water. He said there are more stories of illness in the community than average.

"Scientifically, yes, I know this can't be 100% tied to the nitrates, but it's a pretty huge freaking coincidence," Klipfel contended. "People getting cancer, people having miscarriages, people losing farm animals, horses, cows."

A 39-page amendment to the bill removed key pollution control measures, Lay explained, including a mandate for agencies to review and tighten groundwater pollution permits. He argued the industry has too much influence over the law.

"We need to shift that power back where it belongs," Lay stressed. "That is, to the people who are on the front lines of their pollution. It's to the rural working class, low-income residents."

A report from January showed nitrate levels continued to rise across the Lower Umatilla Basin Groundwater Management Area in Morrow and Umatilla counties. About 40% of tested wells exceeded safe drinking water limits.

Sometimes called the original "ecosystem engineers," beavers and the techniques they use are guiding conservationists in New Mexico to protect scarce water resources.

Defenders of Wildlife is working with a team to install human-made "beaver dam analogs" along two tributaries of the Upper Rio Grande.

Peggy Darr, New Mexico representative for the advocacy group, said like beaver dams, analogs cause water to pond, allowing surrounding soils to soak up moisture during high flows, which restores habitat and encourages beavers to move in.

"The reason that we want to have as many beavers as the systems can hold is because they help keep rivers running year-round, they help to mitigate fire hazards, they help make water cleaner, they also help to reduce damage from flash flooding," Darr outlined.

A recent survey by the group showed a much higher concentration of beaver dams in the northern part of New Mexico, highlighting a need for targeted conservation in less populated regions.

In the Southwest, many perennial rivers now run dry during parts of the year, discouraging the growth of trees, providing a food source for beavers and the wood they use to build their dams. Darr noted the restoration work includes community and tribal outreach about the importance of a nonlethal beaver/human coexistence.

"If you rip out a beaver dam, beavers can rebuild it overnight sometimes, so you'll spend the rest of your life ripping out beaver dams," Darr pointed out. "And if you kill the beavers, it's like putting up a vacancy sign for another beaver pair, and eventually other beavers will move in."

Massive eradication of beavers began in the 1800s, leading to river and stream degradation in New Mexico and across the nation, often made worse by climate change. Darr emphasized conservation tools and public awareness can be beneficial.

"Beavers do millions of dollars of work for free," Darr stressed. "Beaver coexistence and beaver restoration, and just beavers in general, have become high priority for conservation, especially across the West."

Concentrated Animal Feeding Operations, or CAFOs, are banned from the Buffalo National River watershed.

That's after the Arkansas Legislative Council issued a moratorium, outlawing large-scale swine operations on land surrounding the river.

Gordon Watkins, president of the Buffalo River Watershed Alliance, said it's good news for them - but he said he's concerned about other bodies of water around the state that don't have the same protection.

"We've got lots of high-quality recreational streams in the state that deserve to be protected, but our by-laws restrict us to working within the Buffalo River Watershed," said Watkins. "While we would support changes to the regulation, we can't legally take up the leadership role."

Members of the alliance had been fighting for the moratorium since 2013 when C&H Hog Farm opened in the watershed.

Legislators recently passed Act 921, which allows farms to operate anywhere in the state. The Buffalo River is exempt from the legislation.

C&H Hog Farm shut down in 2020, after pressure from environmentalists who said waste from the operation was contaminating surrounding land and water.

Watkins said changes to state rules, such as not contacting local leaders when a company submits an application for a liquid animal waste permit, could impact other rivers and streams.

"Other places in the state are not going to have public notice," said Watkins, "and they're not going to have access to critical information to be able to see if a facility is being built next to them or to see if it's operating properly over time. So, those are our big concerns."

He urged Arkansans to monitor the actions of the Department of Agriculture and the Department of Environmental Quality.

"Be vigilant, pay attention and push for better transparency," said Watkins. "To push the ag department to at least put up a listserv. If they had a listserv where people could sign up for it and they could be guaranteed that they would receive a notice every time an application came up. "

The Arkansas Farm Bureau and the Arkansas Cattlemen's Association argue the moratoriums are government overreach.
