EPA called to address “long-ignored health crisis” in Iowa drinking water
By Carey Gillam
US regulators must take immediate action to address a “long-ignored health crisis” stemming from dangerously contaminated drinking water in Iowa, according to a legal petition filed by environmental and health advocacy groups this week.
The Iowa Environmental Council (IEC) and 12 other organizations are calling for the Environmental Protection Agency (EPA) to take a series of steps to reduce harmful nitrate pollution found in water supplies in Northeast Iowa.
The petition highlights the fact that for many years, nitrate concentrations found in thousands of private wells and some public water sources have exceeded the federal limit of 10 milligrams per liter for drinking water.
State agencies have documented the contamination, but have “failed to do what is needed to correct the pervasive threat to human health,” the petition states.
“For decades, Northeast Iowa residents have been exposed to dangerous levels of nitrate contaminated water,” Food & Water Watch attorney Dani Replogle said in a press release. “As the state reckons with high cancer levels and ongoing pollution regulation rollbacks, federal action is needed to safeguard the right to clean water. EPA must exercise emergency authority to hold polluters accountable and deliver safe drinking water in Iowa.”
Food & Water Watch is among the groups joining IEC in its petition. Others include the Environmental Working Group, the Center for Food Safety, the Environmental Law & Policy Center, and several state organizations.
All signs indicate that “dangerous contamination levels will continue or worsen, absent EPA action,” the petition states.
Farm operations are largely to blame for the contamination, both from the runoff of fertilizer applied to fields of corn and other crops, and the runoff of liquified manure generated by large livestock operations that is also often spread on farm fields. The runoff carries nitrates and phosphorus into surface and groundwaters, and ultimately drinking water.
Iowa is one of the nation’s largest farm states for crops and livestock, and Northeast Iowa is particularly vulnerable to farm pollutants because of its “karst” terrain, which features porous limestone that allows surface pollutants to more quickly move into groundwater. All of the drinking water in the karst region of northeast Iowa depends on groundwater aquifers.
Despite these facts, only a small fraction of private wells are tested regularly for nitrates, which are known to cause health problems at high levels, especially for infants. Cancer is a specific concern with nitrate exposure. Still, more than 1,200 wells in the 12-county karst region tested above the federal threshold for safety from 2016 to 2023, the petition states.
Dire threats seen for America’s ‘most endangered’ rivers
By Johnathan Hettinger
Rivers from Arizona to Alaska, Mississippi to Connecticut, and California to the Carolinas face dire threats from climate change, overdevelopment, pollution and water scarcity, according to a new report released by American Rivers this week.
But this year, the most endangered river isn’t a single one — it’s all of the streams in the entire state of New Mexico, according to the report.
The environmental nonprofit, which focuses on river health and publishes an annual list of most endangered waterways in the US, found that New Mexico is the state most likely to be impacted by a US Supreme Court ruling issued last year in the case of Sackett v. EPA, which stripped federal clean water protections for small streams and wetlands across the country.
The Sackett ruling found that the Clean Water Act only applies to continuous and permanent surface waters, meaning that seasonal rivers and wetlands that aren’t directly connected to rivers aren’t covered by the federal law. Instead, it’s up to states to regulate these bodies of water, which account for more than half of all wetlands and streams in the US.
“These streams and wetlands are the beginning of all of our rivers. And all of that water is connected, so when we lose the protections in our headwaters, those wetlands and streams, our rivers are threatened and the long-term quality of your drinking water will likely be harmed,” Tom Kiernan, president and CEO of American Rivers, said in a video released about the list.
In New Mexico, that means the majority of streams are left unprotected because the state does not have a permitting process in place. That could mean dire downstream consequences for rivers, including the Gila, San Juan, Pecos and Upper Rio Grande.
“People depend on this water. We have depended on this water for hundreds of years. This is our tradition, this is our culture. We don’t want to be a people that loses its traditions because we haven’t taken the right steps to protect our rivers,” Vicente Fernandez, acequia mayordomo and community leader, said in a press release.
“It’s getting worse” – US failing to stem tide of harmful farm pollutants
By Keith Schneider
VENICE, LA. Kindra Arnesen is a 46-year-old commercial fishing boat operator who has spent most of her life among the pelicans and bayous of southern Louisiana, near the juncture where the 2,350-mile-long Mississippi River ends at the Gulf of Mexico.
Clark Porter is a 62-year-old farmer who lives in north-central Iowa where he spends part of his day working as an environmental specialist for the state and the other part raising corn and soybeans on hundreds of acres that his family has owned for over a century.
Though they’ve never met, and live 1,100 miles apart, Arnesen and Porter share a troubling kinship – both of their communities are tied to a deepening water pollution crisis that is fouling the environment and putting public health in peril across multiple US states.
Arnesen’s home lies near an oxygen-depleted expanse of the northern Gulf known as the “dead zone,” where dying algae blooms triggered by contaminants flowing out of the Mississippi River choke off oxygen, suffocating shrimp and other marine life.
Porter’s farm is positioned at the center of the Upper Mississippi River Basin where streams and other surface waters saturated with farm wastes flood into the big river, and contaminated groundwater permeates drinking water wells. Cancer incidence in Iowa is among the nation’s highest, and is rising.
The culprit at the center of it all is a colossal tide of fertilizer and animal manure that runs off fields in Iowa and other farm states to find its way into the Mississippi River. The same agricultural pollution problems are plaguing other iconic US waterways, including Chesapeake Bay and Lake Erie.
US farmers use more fertilizer and spread more manure than in most other countries, accounting for roughly 10% of global fertilizer use, behind China and India. But while the nutrients contained in animal manure and fertilizer are known to nourish crop growth, the resulting nitrogen and phosphorous that end up in waterways are known to create severe health problems for people.
A grand government plan to address the problem has cost taxpayers billions of dollars with minimal results so far, and nowhere is the problem more pronounced than in the Mississippi River Basin.
The reasons for the persistent pollution problem are multi-fold, including strong industry opposition to regulations to control the farm contaminants, and a perverse system in which some government programs incentivize farming practices that add to the pollution even as other government programs try to induce farmers to reduce the pollution.
“You’re talking about systemic dysfunction,” said Matt Liebman, professor emeritus of agronomy and sustainable agriculture at Iowa State University.
Firefighting foam company reaches $750 million PFAS settlement
By Shannon Kelleher
The company Tyco Fire Products today reached a $750 million settlement to help resolve claims related to its firefighting foam, which allegedly contaminated drinking water systems with harmful PFAS chemicals for decades.
Once the settlement is approved, an estimated 7,000 to 8,000 US public water systems could receive money to treat contaminated drinking water, said Joe Rice, co-lead attorney for the plaintiffs with the Motley Rice law firm. Water systems that test positive for PFAS by May 15 may be eligible to benefit from the settlement.
“$750 million towards this problem, that is a huge contribution,” said Rice.
Tyco, a subsidiary of Johnson Controls, does not admit liability or wrongdoing by agreeing to the settlement.
The announcement builds on last summer’s landmark settlements from the companies 3M, Dupont, and others, which could total up to nearly $14 billion to assist affected water systems as they test for and clean up PFAS contamination. 3M’s settlement received final approval April 1.
Earlier this week, US regulators announced the nation’s first legally enforceable limits for levels of six toxic per- and polyfluoroalkyl substances (PFAS) in drinking water, a move the US Environmental Protection Agency (EPA) says should prevent thousands of deaths and reduce serious illnesses in people across the country.
“A huge victory for public health”: EPA set limits on PFAS toxins in drinking water
By Shannon Kelleher
US regulators on Wednesday put in place the nation’s first legally enforceable limits for levels of six toxic PFAS chemicals in drinking water, saying the moves should prevent thousands of deaths and reduce serious illnesses in people across the country.
The rule is designed to reduce exposure to these per-and polyfluoroalkyl substances (PFAS) – also called “forever chemicals” – for about 100 million people nationwide, according to the US Environmental Protection Agency (EPA). Exposure to PFAS has been linked to “deadly cancers, impacts to the liver and heart, and immune and developmental damage to infants and children, the EPA said.
“Today we can celebrate a huge victory for public health in this country,” Rob Bilott, a lawyer who has become famous for his work against PFAS, said in a statement. Bilott has spent decades pushing for PFAS regulations and to hold PFAS manufacturers accountable for releasing the dangerous chemicals into the marketplace.
“It should never have taken this long to address such serious threats to public health and our environment,” Bilott said, noting that he first alerted the EPA to the presence of PFAS in US drinking water more than twenty-three years ago.
The new rule sets a limit of four parts per trillion (ppt) for two types of PFAS – perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), which are both known to be particularly hazardous.
The EPA acknowledged that there is “no level of exposure to these contaminants without risk of health impacts, including certain cancers,” and said it was setting a “non-enforceable health-based goal,” at zero for PFOA and PFOS.
Unsafe levels of PFAS contaminate global water sources, study finds
By Shannon Kelleher
A large part of the world’s surface waters and groundwater contains toxic PFAS chemicals at levels higher than regulators consider safe for drinking water, according to a new analysis of data from more than 45,000 water samples collected from around the world.
The data points to Australia, China, Europe and North America as hotspots for contamination by per- and polyfluoroalkyl substances (PFAS), although the authors suggest this may be skewed due to higher levels of sampling in these regions.
The findings, which were published April 8 in the journal Nature Geoscience, come as regulators in the United States prepare to set the first enforceable drinking water limits for certain types of PFAS. Many US states and other countries have already set regulations for PFAS in drinking water.
“I was surprised to find out the large fraction of source waters that are above drinking water advisory recommendations,” Denis O’Carroll, an engineering professor at the University of New South Wales in Australia and an author of the study, said in a press release.
The number of samples considered unsafe was higher in countries that have stricter PFAS drinking water guidelines and regulations. In Canada, which has one of the strictest recommendations for PFAS in drinking water, 69% of groundwater samples had levels that surpassed that country’s threshold, while only 6% of samples from the European Union failed to meet its criteria.
In “crucial step”, EPA finalizes rule to reduce cancerous chemical plant emissions
By Carey Gillam
More than 200 US chemical plants face new requirements that should slash toxic air pollution and reduce cancer risks for hundreds of thousands of people living near the facilities, officials said on Tuesday.
The action formalizes a hotly debated proposal by the Environmental Protection Agency (EPA) to cut out over 6,000 tons of toxic air pollution annually. The agency is taking specific aim at emissions of ethylene oxide (EtO), which is used in the production of many products and for sterilization of medical equipment, and chloroprene, used to make synthetic rubber.
Most of the impact would be seen in plants in Texas and Louisiana, as well as in the Ohio River Valley, in communities that have become notorious for high rates of cancer. People living near a chloroprene plant in St. John the Baptist Parish, Louisiana, face a cancer risk 50 times higher than the national average, for instance. The community has been dubbed “Cancer Alley.”
“This final rule delivers on EPA’s commitment to protecting public health for all, especially communities historically overburdened by pollution,” EPA Administrator Michael Regan said in a press conference.
An EPA analysis shows that once the final rule is implemented, “no one will again face elevated cancer risks from EtO or chloroprene emissions from the equipment and processes covered by this rule,” Regan said. He said agency actions would cut the cancer risk for people living near the plants by 96%.
The move is part of a “government-wide commitment to ending cancer as we know it,” he said.
An herbicide so hazardous that courts have banned it twice
By Bill Freese
In early February, something rather extraordinary happened in the world of American farming. For the second time, a federal court banned the hazardous herbicide dicamba, which has been wreaking havoc on farmers, rural communities and the natural world for seven long years. The Environmental Protection Agency (EPA) re-approved dicamba after the first court action. Will it do so once again?
What about dicamba makes it so hazardous that courts have overruled EPA twice? It’s an incredibly volatile, drift-prone weed-killer, and extremely potent as well: just one teaspoon over an acre stunts tomato plants. It vaporizes while being sprayed, but also evaporates from plant surfaces and soil days after a spraying operation. Once the vapor is airborne, it forms clouds that drift long distances to kill or injure virtually any flowering plant in its path.
And that’s precisely what happened following Monsanto’s 2016 introduction of soybeans and cotton genetically engineered (GE) to withstand dicamba’s killing effects. Widespread planting of these new GE crops triggered a dramatic upsurge in use during late spring and summer, when heat enhances dicamba’s volatility.
Dicamba has drifted rampantly from these GE fields, damaging millions of acres of non-dicamba-resistant soybeans. Wave after wave of dicamba vapor drift killed fruit trees, or left them with small, unsaleable fruit. Vegetable farms and gardens were devastated. Trees in natural areas suffered. And beekeepers reported steep drops in honey production where dicamba had devasted the flowering plants their bees require for nectar and pollen.
Echoing many of his colleagues, North Dakota pesticide expert Andrew Thostenson stated: “We are in unprecedented, unchartered territory. We’ve never observed anything on this scale since we’ve been using pesticides in the modern era.”
Vermont advances bill targeting oil and gas companies for climate cleanup
By Dana Drugmand
In the aftermath of costly flooding that swept the US Northeast last year, lawmakers in Vermont on Tuesday advanced a proposed new law that aims to make fossil fuel companies liable for the costs of cleaning up communities battered by climate change-related events.
In a 26-3 vote, the state senate passed what state lawmakers are calling the “Climate Superfund Act.” If the bill becomes law, it would be the first of its kind in the country, imposing strict liability for carbon pollution on large oil and gas companies that produce carbon-based fuels. Like the federal Superfund program that holds polluters liable for hazardous waste contamination, the “climate superfund” concept proposes to replicate this polluter pays program for climate pollution.
“I’m proud to vote yes today to respond to the greatest overarching existential threat of our time,” Vermont Sen. Becca White said following the vote.
The measure now moves on to the Vermont House of Representatives, where support appears strong.
“This is a bill that had a lot of support going into the session,” said Ben Edgerly Walsh, climate and energy program director at Vermont Public Interest Research Group. “We’re pretty optimistic that the House is going to take it up and move it before the end of the session.”
Last July, exceedingly heavy rainfall led to damaging flooding in the US Northeast, submerging streets in Vermont’s capital city of Montpelier, as well as thousands of acres of farmland across the state. One hard-hit farming operation, the Intervale Community Farm in Burlington, Vermont, lost an estimated $200,000 of its vegetable crops when 99% of the farm flooded.
Vermont’s bill would assess a one-time fee on fossil fuel companies responsible for more than 1 billion metric tons of greenhouse gas emissions over the last 30 years. The bill leaves the task of determining which companies would pay, and how much each would owe, to the state’s Agency of Natural Resources and the state treasurer, as well as the task of calculating Vermont’s costs of recovering from and adapting to climate impacts.
Concerned about developing babies, EPA warns about danger of weed killer used on farms, golf courses
By Johnathan Hettinger
The US Environmental Protection Agency (EPA) on Monday took the rare step of issuing a warning about “serious, permanent, and irreversible health risks” associated with a chemical used to kill weeds on farms and golf courses and athletic fields.
Citing “significant health risks to pregnant individuals and their developing babies,” the agency said farmworkers and others handling dimethyl tetrachloroterephthalate, more commonly known as DCPA, were at risk, as are people who might play on courses or fields recently sprayed with the pesticide.
The most serious risks extend to the developing babies of pregnant women, especially those handling DCPA products. The agency said pregnant women exposed to DCPA could experience changes to fetal thyroid hormone levels, which are linked to low birth weight, impaired brain development, decreased IQ, and impaired motor skills later in life. Though product labels say people should stay out of fields for 12 hours after they are sprayed with DCPA, the EPA said evidence indicates that in many cases, sprayed fields would be unsafe for 25 days or more. The agency additionally said that mothers and their developing babies could be at risk if they live near areas where DCPA is used because the pesticide can drift.
“EPA has determined that currently registered products containing the herbicide DCPA likely cannot be used under current label directions without posing serious risks of concern in humans,” Ed Messina, director of the Office of Pesticide Programs, stated in a letter to AMVAC, a California-based company that is the sole manufacturer of the pesticide.
The product is primarily used to control weeds on crops such as broccoli, Brussels sprouts, cabbage and onions, though it is also used in some non-agricultural settings. Last year, AMVAC agreed to end its use on turf, citing health concerns.
The EPA is currently reviewing whether to reapprove DCPA. Though the agency rarely takes the step of canceling a pesticide, it is considering that route, including suspending DCPA during review process, the agency said.
“Due to the serious potential risks posed by DCPA use, EPA will be pursuing these regulatory options as soon as practicable,” Messina wrote in the communication to AMVAC.
