The Supreme Court Muddied the Clean Water Act Yet Again

Tuesday, March 4, 2025

The Supreme Court dealt another blow to federal environmental protections on Tuesday in a major water pollution case. In a 5–4 ruling in City and County of San Francisco v. EPA, the justices held that the Environmental Protection Agency could no longer hold certain polluters responsible when the cleanliness of American waterways fell below minimum acceptable standards.Justice Samuel Alito, who wrote for the court, ruled that the agency had gone beyond what the Clean Water Act allowed. “We hold that the two challenged provisions exceed the EPA’s authority,” he wrote. “The text and structure of the CWA, as well as the history of federal water pollution legislation, make this clear. And resorting to such requirements is not necessary to protect water quality.”In a dissenting opinion, Justice Amy Coney Barrett wrote that the majority had badly misread the text and history of the Clean Water Act’s provisions at issue. (The court’s three liberal justices joined her.) But she also argued that her colleagues had done so in pursuit of a specific outcome that was at odds with what Congress had written.“Really, the Court’s argument reduces to the broader policy concern that it may be difficult for regulated entities to comply with receiving water limitations and that they may lack adequate notice of a violation,” she wrote. Those polluters could bring other types of legal challenges in those cases, Barrett explained, but “these concerns do not speak to the relevant question here, which is whether receiving water limitations comport with the Act.”The case represents yet another victory in the Roberts court for polluters, who have again persuaded five conservative justices to adopt stilted readings of environmental laws to reduce their regulatory burdens. The plaintiff in this case—one of the most environmentally conscious cities in the nation—is an unusual one. But the author of the majority opinion was not. Tuesday’s ruling is also a victory for Alito himself, who appears almost eager to rewrite the Clean Water Act more narrowly whenever the opportunity presents itself.At issue in the case is how the Clean Water Act—and, through it, the EPA—regulates offshore water pollution. The question is particularly important for San Francisco. Like many other major U.S. cities, it handles stormwater and wastewater through the same sewage system. That system is able to treat both types of water without issue under normal circumstances.When it rains or snows more than usual, however, the city’s sewer system discharges some of the overflow into the Pacific Ocean. That overflow typically consists of an untreated mixture of wastewater, stormwater, and various urban pollutants. That would violate the Clean Water Act, which generally prohibits the disposal of such pollutants into the nation’s waters.One of the EPA’s tools to combat water pollution under the Clean Water Act is to issue permits for facilities that routinely discharge pollutants into American waterways. Those permits allow the EPA to set certain requirements for would-be polluters to ensure that their outflows meet minimum safety and sanitary thresholds. In exchange for their compliance, permittees are immunized from public or private environmental lawsuits for the duration of the permit, relieving them of the expenses of litigation and short-term regulatory changes.San Francisco is challenging its current permit requirements on multiple grounds. The one that reached the high court in this particular case centered on what Alito called the permit’s “end-result requirements.” In addition to meeting certain minimum requirements at the outset, the EPA also can also levy penalties against permittees if the relevant body of water—which the court calls the “receiving waters”—falls below minimum quality standards.Alito concluded that the Clean Water Act gave the EPA no authority to impose such end-result requirements on would-be polluters. The law allows the agency to impose “any more stringent limitation” that is “necessary to meet” state and federal “water quality standards” established by law or by federal regulation. Alito argued that the term “limitation” only allowed restrictions before the fact, not afterward.“A provision that tells a permittee that it must do certain specific things plainly qualifies as a limitation,” he wrote. “Such a provision imposes a restriction ‘from without.’ But when a provision simply tells a permittee that a particular end result must be achieved and that it is up to the permittee to figure out what it should do, the direct source of restriction or restraint is the plan that the permittee imposes on itself for the purpose of avoiding future liability. In other words, the direct source of the restriction comes from within, not ‘from without.’”Barrett was not persuaded, to say the least. “Limitation,” she wrote, “is simply a synonym for ‘a restrictive condition.’” She noted that “limitations” based on end results were common in everyday life, like a college limiting scholarships to students who maintain a minimum GPA or an employer who limits bonuses to workers based on performance standards. The end-result requirements, Barrett explained, give “practical effect” to water-quality standards “by making them enforceable.”She also emphasized that the plaintiffs would still not be without options to challenge those conditions under her reading of the law. “There is no getting around it: The receiving water limitations are ‘limitations,’” she wrote. “If they are vague or unreasonable, they are vulnerable to challenge on one or both of those grounds. But even a vague or unreasonable limitation is still a ‘limitation.’”Barrett’s reference to Alito’s “broader policy concerns” when it comes to the Clean Water Act is a familiar one. Two years ago, in Sackett v. EPA, he wrote the majority opinion in a decision that sharply limited what types of wetlands count as the “waters of the United States,” the key term for the act’s jurisdiction. Alito held that only wetlands with a “continuous surface connection” to larger bodies of water fell under the Clean Water Act’s terms.In that instance, Justice Brett Kavanaugh dissented from the court’s new interpretation, which he argued was at odds with the statutory text. “The Court’s test narrows the Clean Water Act’s coverage of ‘adjacent’ wetlands to mean only ‘adjoining’ wetlands,” he wrote. “But ‘adjacent’ and ‘adjoining’ have distinct meanings.” Kavanaugh warned at length that the court’s misreading of the statutory text “will leave some long-regulated adjacent wetlands no longer covered by the Clean Water Act, with significant repercussions for water quality and flood control throughout the United States.”In a separate dissent, Justice Elena Kagan agreed with Kavanaugh and argued that Alito’s misreading of the law was driven by his own policy preferences. She pointed to his own phrasing choices that depicted the EPA as a heavy-handed brute and ordinary Americans as its hapless victims. “Congress, [Alito] scolds, has unleashed the EPA to regulate ‘swimming pools and puddles,’ wreaking untold havoc on ‘a staggering array of landowners,’” she wrote. “Surely something has to be done; and who else to do it but this court? It must rescue property owners from Congress’s too-ambitious program of pollution control.”As evidence of his policy views, Kagan cited Alito’s references to “crushing consequences” for those caught in the EPA’s web. Alito—perhaps intentionally, perhaps not—used the same adjective in Tuesday’s ruling. “When a permit contains such requirements,” he wrote in the San Francisco ruling, “a permittee that punctiliously follows every specific requirement in its permit may nevertheless face crushing penalties if the quality of the water in its receiving waters falls below the applicable standards.” (Emphasis mine.)Alito’s opinion only carries the force of law because four of his colleagues agreed to it. At the same time, the opinions in Sackett and San Francisco speak volumes about the court’s priorities and sympathies. Alito hypothesized at one point about a city that “devise[d] a careful plan” for water quality, “diligently implement[ed]” that plan, and still faced “dire potential consequences” if it failed. The EPA is presumed at every turn to be an onerous, malevolent creature; American cities and companies are well-meaning actors who humbly seek the regulatory relief that only the Supreme Court can offer. Alito and his colleagues are all too happy to provide it, even when the Clean Water Act itself doesn’t.

Some big water agencies in farming areas get water for free. Critics say that needs to end

The federal government is providing water to some large agricultural districts for free. In a new study, researchers urge the Trump administration to start charging more for water.

The water that flows down irrigation canals to some of the West’s biggest expanses of farmland comes courtesy of the federal government for a very low price — even, in some cases, for free.In a new study, researchers analyzed wholesale prices charged by the federal government in California, Arizona and Nevada, and found that large agricultural water agencies pay only a fraction of what cities pay, if anything at all. They said these “dirt-cheap” prices cost taxpayers, add to the strains on scarce water, and discourage conservation — even as the Colorado River’s depleted reservoirs continue to decline.“Federal taxpayers have been subsidizing effectively free water for a very, very long time,” said Noah Garrison, a researcher at UCLA’s Institute of the Environment and Sustainability. “We can’t address the growing water scarcity in the West while we continue to give that water away for free or close to it.”The report, released this week by UCLA and the environmental group Natural Resources Defense Council, examines water that local agencies get from the Colorado River as well as rivers in California’s Central Valley, and concludes that the federal government delivers them water at much lower prices than state water systems or other suppliers.The researchers recommend the Trump administration start charging a “water reliability and security surcharge” on all Colorado River water as well as water from the canals of the Central Valley Project in California. That would encourage agencies and growers to conserve, they said, while generating hundreds of millions of dollars to repair aging and damaged canals and pay for projects such as new water recycling plants.“The need for the price of water to reflect its scarcity is urgent in light of the growing Colorado River Basin crisis,” the researchers wrote. The study analyzed only wholesale prices paid by water agencies, not the prices paid by individual farmers or city residents. It found that agencies serving farming areas pay about $30 per acre-foot of water on average, whereas city water utilities pay $512 per acre-foot. In California, Arizona and Nevada, the federal government supplies more than 7 million acre-feet of water, about 14 times the total water usage of Los Angeles, for less than $1 per acre-foot. And more than half of that — nearly one-fourth of all the water the researchers analyzed — is delivered for free by the U.S. Bureau of Reclamation to five water agencies in farming areas: the Imperial Irrigation District, Palo Verde Irrigation District and Coachella Valley Water District, as well as the Truckee-Carson Irrigation District in Nevada and the Unit B Irrigation and Drainage District in Arizona. Along the Colorado River, about three-fourths of the water is used for agriculture.Farmers in California’s Imperial Valley receive the largest share of Colorado River water, growing hay for cattle, lettuce, spinach, broccoli and other crops on more than 450,000 acres of irrigated lands. The Imperial Irrigation District charges farmers the same rate for water that it has for years: $20 per acre-foot. Tina Shields, IID’s water department manager, said the district opposes any surcharge on water. Comparing agricultural and urban water costs, as the researchers did, she said, “is like comparing a grape to a watermelon,” given major differences in how water is distributed and treated.Shields pointed out that IID and local farmers are already conserving, and this year the savings will equal about 23% of the district’s total water allotment. “Imperial Valley growers provide the nation with a safe, reliable food supply on the thinnest of margins for many growers,” she said in an email.She acknowledged IID does not pay any fee to the government for water, but said it does pay for operating, maintaining and repairing both federal water infrastructure and the district’s own system. “I see no correlation between the cost of Colorado River water and shortages, and disagree with these inflammatory statements,” Shields said, adding that there “seems to be an intent to drive a wedge between agricultural and urban water users at a time when collaborative partnerships are more critical than ever.”The Colorado River provides water for seven states, 30 Native tribes and northern Mexico, but it’s in decline. Its reservoirs have fallen during a quarter-century of severe drought intensified by climate change. Its two largest reservoirs, Lake Mead and Lake Powell, are now less than one-third full.Negotiations among the seven states on how to deal with shortages have deadlocked.Mark Gold, a co-author, said the government’s current water prices are so low that they don’t cover the costs of operating, maintaining and repairing aging aqueducts and other infrastructure. Even an increase to $50 per acre-foot of water, he said, would help modernize water systems and incentivize conservation. A spokesperson for the U.S. Interior Department, which oversees the Bureau of Reclamation, declined to comment on the proposal.The Colorado River was originally divided among the states under a 1922 agreement that overpromised what the river could provide. That century-old pact and the ingrained system of water rights, combined with water that costs next to nothing, Gold said, lead to “this slow-motion train wreck that is the Colorado right now.” Research has shown that the last 25 years were likely the driest quarter-century in the American West in at least 1,200 years, and that global warming is contributing to this megadrought.The Colorado River’s flow has decreased about 20% so far this century, and scientists have found that roughly half the decline is due to rising temperatures, driven largely by fossil fuels.In a separate report this month, scientists Jonathan Overpeck and Brad Udall said the latest science suggests that climate change will probably “exert a stronger influence, and this will mean a higher likelihood of continued lower precipitation in the headwaters of the Colorado River into the future.” Experts have urged the Trump administration to impose substantial water cuts throughout the Colorado River Basin, saying permanent reductions are necessary. Kathryn Sorensen and Sarah Porter, researchers at Arizona State University’s Kyl Center for Water Policy, have suggested the federal government set up a voluntary program to buy and retire water-intensive farmlands, or to pay landowners who “agree to permanent restrictions on water use.”Over the last few years, California and other states have negotiated short-term deals and as part of that, some farmers in California and Arizona are temporarily leaving hay fields parched and fallow in exchange for federal payments.The UCLA researchers criticized these deals, saying water agencies “obtain water from the federal government at low or no cost, and the government then buys that water back from the districts at enormous cost to taxpayers.”Isabel Friedman, a coauthor and NRDC researcher, said adopting a surcharge would be a powerful conservation tool. “We need a long-term strategy that recognizes water as a limited resource and prices it as such,” she wrote in an article about the proposal.

California cities pay a lot for water; some agricultural districts get it for free

Even among experts the cost of water supplies is hard to pin down. A new study reveals huge differences in what water suppliers for cities and farms pay for water from rivers and reservoirs in California, Arizona and Nevada.

In summary Even among experts the cost of water supplies is hard to pin down. A new study reveals huge differences in what water suppliers for cities and farms pay for water from rivers and reservoirs in California, Arizona and Nevada. California cities pay far more for water on average than districts that supply farms — with some urban water agencies shelling out more than $2,500 per acre-foot of surface water, and some irrigation districts paying nothing, according to new research.  A report published today by researchers with the UCLA Institute of the Environment and Sustainability and advocates with the Natural Resources Defense Council shines a light on vast disparities in the price of water across California, Arizona and Nevada.  The true price of water is often hidden from consumers. A household bill may reflect suppliers’ costs to build conduits and pump water from reservoirs and rivers to farms and cities. A local district may obtain water from multiple sources at different costs. Even experts have trouble deciphering how much water suppliers pay for the water itself. The research team spent a year scouring state and federal contracts, financial reports and agency records to assemble a dataset of water purchases, transfers and contracts to acquire water from rivers and reservoirs. They compared vastly different water suppliers with different needs and geographies, purchasing water from delivery systems built at different times and paid for under different contracts. Their overarching conclusion: One of the West’s most valuable resources has no consistent valuation – and sometimes costs nothing at all.  Cities pay the highest prices for water. Look up what cities or irrigation districts in California, Nevada and Arizona pay for surface water in our interactive database at calmatters.org “It costs money to move water around,” the report says, “but there is no cost, and no price signal, for the actual water.” That’s a problem, the authors argue, as California and six other states in the Colorado River basin hash out how to distribute the river’s dwindling flows — pressed by federal ultimatums, and dire conditions in the river’s two major reservoirs. The study sounds the alarm that the price of water doesn’t reflect its growing scarcity and disincentivizes conservation. “We’re dealing with a river system and water supply source that is in absolute crisis and is facing massive shortfalls … and yet we’re still treating this as if it’s an abundant, limitless resource that should be free,” said Noah Garrison, environmental science practicum director at UCLA and lead author on the study.  Jeffrey Mount, senior fellow at the Public Policy Institute of California, applauded the research effort. Though he had not yet reviewed the report, he said complications abound, built into California’s water infrastructure itself and amplified by climate change. Moving, storing and treating water can drive up costs, and are only sometimes captured in the price.  “We’ve got to be careful about pointing our fingers and saying farmers are getting a free ride,” Mount said. Still, he agreed that water is undervalued: “We do not pay the full costs of water — the full social, full economic and the full environmental costs of water.”  Coastal cities pay the most The research team investigated how much suppliers above a certain purchase threshold spend on water from rivers and reservoirs in California, Arizona and Nevada.  They found that California water suppliers pay more than double on average than what Nevada districts pay for water, and seven times more than suppliers in Arizona.  The highest costs span the coast between San Francisco and San Diego, which the researchers attributed to the cost of delivery to these regions and water transfers that drive up the price every time water changes hands.  “In some of those cases it’s almost a geographic penalty for California, that there are larger conveyance or transport and infrastructure needs, depending on where the districts are located,” Garrison said.  Agricultural water districts pay the least In California, according to the authors, cities pay on average 20 times more than water suppliers for farms — about $722 per acre foot, compared to $36.  One acre foot can supply roughly 11 Californians for a year, according to the state’s Department of Water Resources.  Five major agricultural suppliers paid nothing to the federal government for nearly 4 million acre-feet of water, including three in California that receive Colorado River water: the Imperial Irrigation District, the Coachella Valley Water District and the Palo Verde Irrigation District.  Tina Anderholt Shields, water manager for the Imperial Irrigation District, which receives the single largest share of Colorado River water, said the district’s contract with the U.S. government does not require any payment for the water.  Cities, by contrast, received less than 40,000 acre-feet of water for $0. The report notes, however, that the Metropolitan Water District of Southern California, a major urban water importer, spends only 25 cents an acre-foot for around 850,000 acre-feet of water from the Colorado River.  Bill Hasencamp, manager of Colorado River resources at Metropolitan, said that the true cost of this water isn’t reflected in the 25-cent fee, because the expense comes from moving it. By the time the Colorado River water gets to the district, he said it costs several hundred dollars. Plus, he added, the district pays for hydropower, which helps cover the costs of the dams storing the water supply. “That enables us to only pay 25 cents an acre foot to the feds on the water side, because we’re paying Hoover Dam costs on the power side.” Federal supplies are the cheapest; transfers drive up costs Much of the difference among water prices across three states comes down to source: those whose supplies come from federally managed rivers, reservoirs, aqueducts and pumps pay far less on average than those receiving water from state managed distribution systems or via water transfers.  Garrison and his team proposed adding a $50 surcharge per acre-foot of cheap federal supplies to help shore up the infrastructure against leaks and losses or pay for large-scale conservation efforts without tapping into taxpayer dollars.  But growers say that would devastate farming in California.  “It’s important to note that the ‘value’ of water is priceless,” said Allison Febbo, General Manager of Westlands Water District, which supplies San Joaquin Valley farms. The report calculates that the district pays less than $40 per acre foot for water from the federal Central Valley Project, though the Westlands rate structure notes another $14 fee to a restoration fund. “The consequences of unaffordable water can be seen throughout our District: fallowed fields, unemployment, decline in food production…” The Imperial Irrigation District’s Shields said that a surcharge would be inconsistent with their contract, difficult to implement, and unworkable for growers.  “It’s not like farmers can just pass it on to their buyers and then have that roll down to the consumer level where it might be ‘manageable,’” Shields said. The most expensive water in California is more than $2,800 an acre-foot The most expensive water in California, Arizona or Nevada flows from the rivers of Northern California, down California’s state-managed system of aqueducts and pumps, to the San Gorgonio Pass Water Agency in Riverside County. Total cost, according to the report: $2,870.21 per acre foot.  Lance Eckhart, the agency’s general manager, said he hadn’t spoken to the study’s authors but that the number sounded plausible. The price tag would make sense, he said, if it included contributing to the costs for building and maintaining the 705-mile long water delivery system, as well as for the electricity needed to pump water over mountains.  Eckhart compared the water conveyance to a railroad, and his water agency to a distant, distant stop. “We’re at the end, so we have the most railroad track to pay for, and also the most energy costs to get it down here,” he said.  Because it took decades for construction of the water delivery system to reach San Gorgonio Pass, the water agency built some of those costs into local property taxes before the water even arrived, rather than into the water bills for the cities and towns they supply. As a result, its mostly municipal customers pay only $399 per acre foot, Eckhart said.  “You can’t build it into rates if you’re not going to see your first gallon for 40 years,” Ekhart said.  The study didn’t interrogate how the wholesale price of imported water translates to residential bills. Water managers point out that cheap supplies like groundwater can help dilute the costs of pricey imported water.  The Los Angeles Department of Water and Power, for instance, purchases water imported from the Colorado River and Northern California to fill gaps left by local groundwater stores, supplies from the Owens Valley, and other locally managed sources, said Marty Adams, the utility’s former general manager. (The Los Angeles Department of Water and Power was unable to provide an interview.) Because the amount of water needed can vary from year to year, it’s added as an additional charge on top of the base rate, Adams said. “If you have to pay for purchased water somewhere, when you add all the numbers up, it comes out in that total,” he said.  “The purchased water becomes the wildcard all the time.”

Drinking water contaminated with Pfas chemicals probably increases the risk of infant mortality and other harm to newborns, a new peer-reviewed study of 11,000 births in New Hampshire finds.The first-of-its-kind University of Arizona research found drinking well water down gradient from a Pfas-contaminated site was tied to an increase in infant mortality of 191%, pre-term birth of 20%, and low-weight birth of 43%.It was also tied to an increase in extremely premature birth and extremely low-weight birth by 168% and 180%, respectively.The findings caught authors by surprise, said Derek Lemoine, a study co-author and economics professor at the University of Arizona who focuses on environmental policymaking and pricing climate risks.“I don’t know if we expected to find effects this big and this detectable, especially given that there isn’t that much infant mortality, and there aren’t that many extremely low weight or pre-term births,” Lemoine said. “But it was there in the data.”The study also weighed the cost of societal harms in drinking contaminated water against up-front cleanup costs, and found it to be much cheaper to address Pfas water pollution.Extrapolating the findings to the entire US population, the authors estimate a nearly $8bn negative annual economic impact just in increased healthcare costs and lost productivity. The cost of complying with current regulations for removing Pfas in drinking water is estimated at about $3.8bn.“We are trying to put numbers on this and that’s important because when you want to clean up and regulate Pfas, there’s a real cost to it,” Lemoine said.Pfas are a class of at least 16,000 compounds often used to help products resist water, stains and heat. They are called “forever chemicals” because they do not naturally break down and accumulate in the environment, and they are linked to serious health problems such as cancer, kidney disease, liver problems, immune disorders and birth defects.Pfas are widely used across the economy, and industrial sites that utilize them in high volume often pollute groundwater. Military bases and airports are among major sources of Pfas pollution because the chemicals are used in firefighting foam. The federal government estimated that about 95 million people across the country drink contaminated water from public or private wells.Previous research has raised concern about the impact of Pfas exposure on fetuses and newborns.Among those are toxicological studies in which researchers examine the chemicals’ impact on lab animals, but that leaves some question about whether humans experience the same harms, Lemoine said.Other studies are correlative and look at the levels of Pfas in umbilical cord blood or in newborns in relation to levels of disease. Lemoine said those findings are not always conclusive, in part because many variables can contribute to reproductive harm.The new natural study is unique because it gets close to “isolating the effect of the Pfas itself, and not anything around it”, Lemoine said.Researchers achieved this by identifying 41 New Hampshire sites contaminated with Pfoa and Pfos, two common Pfas compounds, then using topography data to determine groundwater flow direction. The authors then examined reproductive outcomes among residents down gradient from the sites.Researchers chose New Hampshire because it is the only state where Pfas and reproductive data is available, Lemoine said. Well locations are confidential, so mothers were unaware of whether their water source was down gradient from a Pfas-contaminated site. That created a randomization that allows for causal inference, the authors noted.The study’s methodology is rigorous and unique, and underscores “that Pfas is no joke, and is toxic at very low concentrations”, said Sydney Evans, a senior science analyst with the Environmental Working Group non-profit. The group studies Pfas exposures and advocates for tighter regulations.The study is in part effective because mothers did not know whether they were exposed, which created the randomization, Evans said, but she noted that the state has the information. The findings raise questions about whether the state should be doing a similar analysis and alerting mothers who are at risk, Evans said.Lemoine said the study had some limitations, including that authors don’t know the mothers’ exact exposure levels to Pfas, nor does the research account for other contaminants that may be in the water. But he added that the findings still give a strong picture of the chemicals’ effects.Granular activated carbon or reverse osmosis systems can be used by water treatment plants and consumers at home to remove many kinds of Pfas, and those systems also remove other contaminants.The Biden administration last year put in place limits in drinking water for six types of Pfas, and gave water utilities several years to install systems.The Trump administration is moving to undo the limits for some compounds. That would probably cost the public more in the long run. Utility customers pay the cost of removing Pfas, but the public “also pays the cost of drinking contaminated water, which is bigger”, Lemoine said.
