‘No way, not possible’: California has a plan for new water rules. Will it save salmon from extinction?

News Feed
Monday, December 16, 2024

In summary Growers and cities support the Newsom administration proposal, saying it strikes a balance for uses of Delta water. But environmentalists say the “healthy rivers” rules would actually harm California’s iconic salmon. The Newsom administration is refining a contentious set of proposed rules, years in the making, that would reshape how farms and cities draw water from the Central Valley’s Delta and its rivers. Backed by more than $1 billion in state funds, the rules, if adopted, would require water users to help restore rivers and rebuild depleted Chinook salmon runs.   The administration touts its proposed rules as the starting point of a long-term effort to double Central Valley Chinook populations from historical levels, reaching numbers not seen in at least 75 years. But environmental groups have almost unanimously rejected it, saying it promises environmental gains that will never materialize and jeopardizes the existence of California’s iconic salmon and other fish. “There is no way the assets they’ve put on the table, water and habitat combined, are going to achieve the doubling goal — no way, not possible,” said Jon Rosenfield, science director with San Francisco Baykeeper.  Dubbed Healthy Rivers and Landscapes but better known as “the voluntary agreements,” the proposal is one of two pathways for state officials as they update a keystone regulatory document called the Bay-Delta Water Quality Control Plan, which was last overhauled in 1995. With the ecosystem of the Bay-Delta in the throes of collapse, the set of rules is critical to determining how much water flows through the Delta for salmon and other species and how much is available for growers and cities in the Central Valley and Southern California. Once vital to indigenous cultures and the coastal ecosystem, Chinook salmon and other native fish have declined for decades due to dam operations, water diversions, increased water temperatures and marine food web issues. Numbers of spawning adult Chinook have dropped so low that all commercial and recreational salmon fishing has been banned for two years in a row, and preliminary numbers this year show no signs of recovery.  State officials from multiple agencies have lauded the Healthy Rivers program — which would meter out flows for fish while mandating restoration of floodplains and other river features — as their preferred option for updating the plan. California’s most influential water districts, serving tens of millions of people and most of the Central Valley’s farmland, have rallied behind the state’s preferred option, which has taken center stage during public workshops since November. Newsom administration officials have worked on these rules for years during negotiations with the San Joaquin Valley’s Westlands Water District, the nation’s largest agricultural water provider, the giant Metropolitan Water District of Southern California and other water users. California Resources Secretary Wade Crowfoot described the proposal as “a new and strengthened approach” that will protect both the environment and the water supply.  Crowfoot told the water board that the proposed rules would do “a good job working to balance all of (Californians’) needs, and ultimately help the environment to recover in ways that’s workable for communities across our state.”  Such a balance has long eluded state officials. “This is progress,” Chuck Bonham, director of the California Department of Fish and Wildlife, said at a November water board workshop. “It’s gone on so long. It’s time.”  Back in 2020, Gov. Gavin Newsom endorsed the “voluntary agreement” approach. “Today, I am committing to achieving a doubling of California’s salmon population by 2050. These agreements will be foundational to meeting that goal,” he wrote in a CalMatters opinion piece. The rules would do “a good job working to balance all of (Californians’) needs, and ultimately help the environment to recover in ways that’s workable for communities across our state.” California resources Secretary Wade Crowfoot Nina Hawk, the Bay-Delta Initiatives group manager with the Metropolitan Water District — which provides water that serves 19 million Southern Californians — said the Newsom proposal would create an equitable pathway to meeting human and environmental water demands. “It is important that we try to balance what the state board defines as beneficial uses … both for the environment and for farms, in a way that looks at the integrity of the water system and also for the state of California’s natural resources and its economy,” Hawk said.   Kevin Padway of the Zone 7 Water Agency, which serves 270,000 East Bay residents, encouraged the water board to adopt the rules, commending them as an “immediately implementable” route to balancing water demands for people and environmental uses.

Photo by Ken James, California Department of Water Resources But environmentalists aren’t sold. Some have even refused to call it by its formal name, saying it’s a euphemism with no bearing on “healthy rivers.” They say the rules would favor water users, allowing cities and farms to draw so much water from the Delta and its tributary rivers that salmon will continue their long decline. They say the proposed rules simply don’t offer fish the water they need, let alone support the state’s salmon rebuilding mandate.  “If you’re diverting more than half of a river’s flow, you are guaranteeing negative population growth” of salmon, said Gary Bobker, Friends of the River’s program director. The complex flow rules could even allow growers to entirely drain some rivers in critically dry years, according to Barry Nelson, a water policy analyst with the Golden State Salmon Association who spoke at a recent board workshop. “Dewatering rivers during droughts would be completely consistent with the Bay-Delta Plan,” he said.  The State Water Resources Control Board is the agency with the authority to approve the rules. A public hearing and vote could come in 2025. The water board’s other option would require strict minimum flows in rivers. Water users say those rules would have unacceptable impacts on farms, hydropower and communities — including planned housing projects — while environmentalists and tribes laud it as more protective of fish. It would ensure that rivers contain an average of 55% of the total water available in the watershed at a given time — a measure called unimpaired flow. While momentum has built behind the state’s Healthy Rivers plan, the state water board could still go either way with their vote. It is even possible that officials adopt both options, with the unimpaired flow pathway reserved as a regulatory backstop, should the Newsom proposal fail, or as concurrent rules applied to waters users who opt out of the voluntary agreements.   Doubling Chinook runs — is it a stream dream A longstanding mandate requires fishery and water managers to double the Central Valley’s population of naturally reproducing Chinook salmon from levels observed between 1967 and 1991. This would translate into an average of 990,000 spawning Chinook each year, almost 10 times recent averages. State officials say their Healthy Rivers plan would help to realize this goal. Around year-eight — when the program could be extended — officials hope to be about 25% of the way to the doubling goal, said Louise Conrad, lead scientist with the state Department of Water Resources.   “Salmon runs could potentially be extinct by then with the flow assets they’re putting forward.”Ashley Overhouse, defenders of wildlife Officials with the National Marine Fisheries Service, in a January letter to the state, said the eight-year timeframe “is concerning, given the dire status of native fish species within the Sacramento River Basin and Delta.” The U.S. Environmental Protection Agency, in comments emailed to the Water Board in January, noted the light water allowances in critically dry years. “EPA is concerned that the total volume and timing of Delta inflow and outflow provided under the proposed VA (voluntary agreement) alternative relative to baseline is not large enough to adequately restore and protect aquatic ecosystems,” the agency wrote.  Fall-run Chinook salmon migrate and spawn in the Feather River near the Feather River Fish Hatchery in Oroville on Nov. 15, 2024.

Photo by Xavier Mascareñas, California Department of Water Resources This target of doubling Chinook is nothing new. The almost legendary “doubling goal” has been on the books since the early 1990s, when federal law set the deadline for 2002.  Now the state’s proposed rules would punt it to 2050 — what salmon advocates say is much too far away for a species already on the brink and a vanishing fishing industry. “Salmon runs could potentially be extinct by then with the flow assets they’re putting forward,” said Ashley Overhouse, Defenders of Wildlife’s water policy advisor. Representatives of California tribes, who historically relied on Chinook as a dietary mainstay, say they were excluded from planning discussions.  “The only people that have been at the table talking about the voluntary agreements are water agencies, water contractors, irrigation districts, and private companies,” said Gary Mulcahy, government liaison for the Winnemem Wintu Tribe. “They (state officials) have excluded tribes, disadvantaged communities, environmental justice communities for nine years.” State officials “have excluded tribes, disadvantaged communities, environmental justice communities for nine years.”Gary Mulcahy, Winnemem Wintu Tribe But the flow rules environmentalists and tribes prefer would cut deep into urban and agricultural water supplies, causing “impacts far and wide” on water exports from the Delta, storage in upstream reservoirs and hydropower production, said Jennifer Pierre, general manager of the State Water Contractors, which represents 27 water agencies that serve 750,000 acres of farmland and 27 million people. Farmers, she said, would experience substantial permanent economic losses, forcing widespread fallowing of their crops. San Joaquin Valley growers would lose more than a quarter of their water in dry years, and 13% on average for all years, according to the draft rules. Thaddeus Bettner, executive director of the Sacramento River Settlement Contractors — a group of farmers who largely grow rice  — said it would force as much as 30% of his district’s 450,000 irrigated acres out of production, with harder impacts on growers with little groundwater to fall back on.  Rice farmer Jon Munger, with 13,000 acres on the east side of the Sacramento Valley, said, in some years, the unimpaired flow approach favored by environmentalists could strip him of virtually all of his water in summer months. His groundwater supply is very limited. “We wouldn’t have any water to grow rice,” he said.  That option would also squeeze residential water use. The Placer County Water Agency, which serves about a quarter-million residents northeast of Sacramento, would lose almost half its supply, threatening initiatives to accommodate a growing population, said General Manager Andrew Fecko.  It would cost Southern California a big chunk of its municipal water, too.  Under the environmentalists’ option, “we wouldn’t have sufficient water supply. It would be a decline at the taps, it would be a decline for businesses.”Nina Hawk, Metropolitan Water District of Southern California “We wouldn’t have sufficient water supply,” said Hawk at the Metropolitan Water District. “It would be a decline at the taps, it would be a decline for businesses.” Billions of dollars in new salmon habitat The program proposes restoring 45,000 acres of structural habitat, like floodplains, tidal marshes, in-river piles of woody debris and gravel spawning beds over the next eight years.  Thousands of acres are already completed or underway. This, according to Overhouse at Defenders of Wildlife, leaves roughly 30,000 planned acres that would be brand new additions to the ecosystem — which she and others say would mute the promised benefits of the program.  All of this will cost money, and to date $2.4 billion in public funds have been secured to support the flow measures and the habitat restoration. Another $500 million may be needed. The state’s proposed rules would allocate to the Sacramento River system between 100,000 and 700,000 acre-feet of water per year, depending on how much precipitation has fallen. But environmentalists say this isn’t nearly enough. They also worry that regulatory loopholes would allow future water projects — such as the Sites Reservoir, for which Newsom advocated at a public appearance last week — to divert water that would be protected if the state adopted unimpaired flow rules. “It is not an accident that they haven’t solved this problem,” Nelson, with the Salmon Association, said. “The VAs (voluntary agreements) and the Delta tunnel and Sites are a package.”  Some conservationists are optimistic about the state’s proposal. Rene Henery, California science director with Trout Unlimited, thinks more habitat and water — especially in dry years — will be needed to protect salmon. But he also thinks the rules could succeed, as long as it’s just the first step of many in a flexible and collaborative restoration process — something he and a team of colleagues are trying to initiate with a state-funded project called Reorienting to Recovery.   UC Davis fish biologist Carson Jeffres, who has studied floodplain restoration projects, also said the salmon doubling objective is achievable through the Newsom proposal as long as state officials “have the courage to be nimble and adjust and adapt if it looks like things aren’t going as planned.” Tribal water rights advocate Regina Chichizola, executive director of Save California Salmon, rejected the Newsom administration’s notion that the state balances competing needs and demands.  “We’ve compromised so much that we’re facing an extinction crisis, that tribes don’t have fish for ceremonies,” she told the board in an emotional public comment last week. “Of course I want to make sure that all of the cities have access to water, but in the end agriculture is going to have to use less water,” she said. “The job of the water board is not to make everyone happy, it’s to protect beneficial uses and clean water, and if the salmon go extinct on your watch, that’s something that you’re going to have to tell your grandkids about.” A third straight year with no California salmon fishing?  Early fish counts suggest it could happen October 30, 2024October 30, 2024 Is a new plan for delivering Delta water worse than Trump’s rules?

The U.S. Environmental Protection Agency, in comments emailed to the Water Board in January, noted the light water allowances in critically dry years.

“EPA is concerned that the total volume and timing of Delta inflow and outflow provided under the proposed VA (voluntary agreement) alternative relative to baseline is not large enough to adequately restore and protect aquatic ecosystems,” the agency wrote.

A rare glimpse inside the mountain tunnel that carries water to Southern California

In the 1930s, workers bored a 13-mile tunnel beneath Mt. San Jacinto. Here's a look inside the engineering feat that carries Colorado River water to Southern California.

Thousands of feet below the snowy summit of Mt. San Jacinto, a formidable feat of engineering and grit makes life as we know it in Southern California possible. The 13-mile-long San Jacinto Tunnel was bored through the mountain in the 1930s by a crew of about 1,200 men who worked day and night for six years, blasting rock and digging with machinery. Completed in 1939, the tunnel was a cornerstone in the construction of the 242-mile Colorado River Aqueduct. It enabled the delivery of as much as 1 billion gallons of water per day.The tunnel is usually off-limits when it is filled and coursing with a massive stream of Colorado River water. But recently, while it was shut down for annual maintenance, the Metropolitan Water District of Southern California opened the west end of the passage to give The Times and others a rare look inside. “It’s an engineering marvel,” said John Bednarski, an assistant general manager of MWD. “It’s pretty awe-inspiring.” The 16-foot-diameter San Jacinto Tunnel runs 13 miles through the mountain. While shut down for maintenance, the tunnel has a constant stream of water entering from the mountain. A group visits the west end of the San Jacinto Tunnel, where the mouth of the water tunnel enters a chamber. He wore a hard hat as he led a group to the gaping, horseshoe-shaped mouth of the tunnel. The passage’s concrete arch faded in the distance to pitch black.The tunnel wasn’t entirely empty. The sound of rushing water echoed from the walls as an ankle-deep stream flowed from the portal and cascaded into a churning pool beneath metal gates. Many in the tour group wore rubber boots as they stood on moist concrete in a chamber faintly lit by filtered sunlight, peering into the dark tunnel. This constant flow comes as groundwater seeps and gushes from springs that run through the heart of the mountain. In places deep in the tunnel, water shoots so forcefully from the floor or the wall that workers have affectionately named these soaking obstacles “the fire hose” and “the car wash.”Standing by the flowing stream, Bednarski called it “leakage water from the mountain itself.”Mt. San Jacinto rises 10,834 feet above sea level, making it the second-highest peak in Southern California after 11,503-foot Mt. San Gorgonio.As the tunnel passes beneath San Jacinto’s flank, as much as 2,500 feet of solid rock lies overhead, pierced only by two vertical ventilation shafts. Snow covers Mt. San Jacinto, as seen from Whitewater, in March. At the base of the mountain, the 13-mile San Jacinto Tunnel starts its journey. The tunnel transports Colorado River water to Southern California’s cities. During maintenance, workers roll through on a tractor equipped with a frame bearing metal bristles that scrape the tunnel walls, cleaning off algae and any growth of invasive mussels. Workers also inspect the tunnel by passing through on an open trailer, scanning for any cracks that require repairs.“It’s like a Disneyland ride,” said Bryan Raymond, an MWD conveyance team manager. “You’re sitting on this trailer, and there’s a bunch of other people on it too, and you’re just cruising through looking at the walls.” Aside from the spraying and trickling water, employee Michael Volpone said he has also heard faint creaking.“If you sit still and listen, you can kind of hear the earth move,” he said. “It’s a little eerie.”Standing at the mouth of the tunnel, the constant babble of cascading water dominates the senses. The air is moist but not musty. Put a hand to the clear flowing water, and it feels warm enough for a swim. On the concrete walls are stained lines that extend into the darkness, marking where the water often reaches when the aqueduct is running full. Many who have worked on the aqueduct say they are impressed by the system’s design and how engineers and workers built such a monumental system with the basic tools and technology available during the Great Depression.Pipelines and tunnelsThe search for a route to bring Colorado River water across the desert to Los Angeles began with the signing of a 1922 agreement that divided water among seven states. After the passage of a $2-million bond measure by Los Angeles voters in 1925, hundreds of surveyors fanned out across the largely roadless Mojave and Sonoran deserts to take measurements and study potential routes.The surveyors traveled mostly on horseback and on foot as they mapped the rugged terrain, enduring grueling days in desert camps where the heat sometimes topped 120 degrees.Planners studied and debated more than 100 potential paths before settling on one in 1931. The route began near Parker, Ariz., and took a curving path through desert valleys, around obstacles and, where there was no better option, through mountains.In one official report, a manager wrote that “to bore straight through the mountains is very expensive and to pump over them is likewise costly.” He said the planners carefully weighed these factors as they decided on a solution that would deliver water at the lowest cost. VIDEO | 02:45 A visit to the giant tunnel that brings Colorado River water to Southern California Share via Those in charge of the Metropolitan Water District, which had been created in 1928 to lead the effort, were focused on delivering water to 13 participating cities, including Los Angeles, Burbank and Anaheim. William Mulholland, Los Angeles’ chief water engineer, had led an early scouting party to map possible routes from the Colorado River to Southern California’s cities in 1923, a decade after he celebrated the completion of the 233-mile aqueduct from the Owens Valley to Los Angeles with the triumphant words, “There it is. Take it.”The aqueduct’s design matched the audaciousness of the giant dams the federal government was starting to build along the Colorado — Hoover Dam (originally called Boulder Dam) and Parker Dam, which formed the reservoir where the aqueduct would begin its journey.Five pumping plants would be built to lift water more than 1,600 feet along the route across the desert. Between those points, water would run by gravity through open canals, buried pipelines and 29 separate tunnels stretching 92 miles — the longest of which was a series of nine tunnels running 33.7 miles through hills bordering the Coachella Valley.To make it possible, voters in the district’s 13 cities overwhelmingly approved a $220-million bond in 1931, the equivalent of a $4.5-billion investment today, which enabled the hiring of 35,000 workers. Crews set up camps, excavated canals and began to blast open shafts through the desert’s rocky spines to make way for water.In 1933, workers started tearing into the San Jacinto Mountains at several locations, from the east and the west, as well as excavating shafts from above. Black-and-white photographs and films showed miners in hard hats and soiled uniforms as they stood smoking cigarettes, climbing into open rail cars and running machinery that scooped and loaded piles of rocks.Crews on another hulking piece of equipment, called a jumbo, used compressed-air drills to bore dozens of holes, which were packed with blasting power and detonated to pierce the rock. (Courtesy of Metropolitan Water District of Southern California) The work progressed slowly, growing complicated when the miners struck underground streams, which sent water gushing in.According to a 1991 history of the MWD titled “A Water Odyssey,” one flood in 1934 disabled two of three pumps that had been brought in to clear the tunnel. In another sudden flood, an engineer recalled that “the water came in with a big, mad rush and filled the shaft to the top. Miners scrambled up the 800-foot ladder to the surface, and the last man out made it with water swirling around his waist.”Death and delaysAccording to the MWD’s records, 13 workers died during the tunnel’s construction, including men who were struck by falling rocks, run over by equipment or electrocuted with a wire on one of the mining trolleys that rolled on railroad tracks. The Metropolitan Water District had originally hired Wenzel & Henoch Construction Co. to build the tunnel. But after less than two years, only about two miles of the tunnel had been excavated, and the contractor was fired by MWD general manager Frank Elwin “F.E.” Weymouth, who assigned the district’s engineers and workers to complete the project.Construction was delayed again in 1937 when workers went on strike for six weeks. But in 1939, the last wall of rock tumbled down, uniting the east and west tunnels, and the tunnel was finished. John Bednarski, assistant general manager of the Metropolitan Water District of Southern California, stands in a water tunnel near the end point of the larger San Jacinto Tunnel, which carries Colorado River water. The total cost was $23.5 million. But there also were other costs. As the construction work drained water, many nearby springs used by the Native Soboba people stopped flowing. The drying of springs and creeks left the tribe’s members without water and starved their farms, which led to decades of litigation by the Soboba Band of Luiseño Indians and eventually a legal settlement in 2008 that resolved the tribe’s water rights claims.The ‘magic touch’ of waterBy the time the tunnel was completed, the Metropolitan Water District had released a 20-minute film that was shown in movie theaters and schools celebrating its conquest of the Colorado River and the desert. It called Mt. San Jacinto the “tallest and most forbidding barrier.”In a rich baritone, the narrator declared Southern California “a new empire made possible by the magic touch of water.” “Water required to support this growth and wealth could not be obtained from the local rainfall in this land of sunshine,” the narrator said as the camera showed newly built homes and streets filled with cars and buses. “The people therefore realized that a new and dependable water supply must be provided, and this new water supply has been found on the lofty western slopes of the Rocky Mountains, a wonderland of beauty, clad by nature in a white mantle of snow.”Water began to flow through the aqueduct in 1939 as the pumping plants were tested. At the Julian Hinds Pumping Plant, near the aqueduct’s halfway point, water was lifted 441 feet, surging through three pipelines up a desert mountain.

(Los Angeles Times) From there, the water flowed by gravity, moving at 3-6 mph as it traveled through pipelines, siphons and tunnels. It entered the San Jacinto Tunnel in Cabazon, passed under the mountain and emerged near the city of San Jacinto, then continued in pipelines to Lake Mathews reservoir in Riverside County. In 1941, Colorado River water started flowing to Pasadena, Beverly Hills, Compton and other cities. Within six years, another pipeline was built to transport water from the aqueduct south to San Diego.The influx of water fueled Southern California’s rapid growth during and after World War II.Over decades, the dams and increased diversions also took an environmental toll, drying up much of the once-vast wetlands in Mexico’s Colorado River Delta. John Bednarski, assistant general manager of the Metropolitan Water District, walks in a water tunnel near the end point of the larger San Jacinto Tunnel. An impressive designToday, 19 million people depend on water delivered by the MWD, which also imports supplies from Northern California through the aqueducts and pipelines of the State Water Project.In recent decades, the agency has continued boring tunnels where needed to move water. A $1.2-billion, 44-mile-long conveyance system called the Inland Feeder, completed in 2009, involved boring eight miles of tunnels through the San Bernardino Mountains and another 7.9-mile tunnel under the Badlands in Riverside County.The system enabled the district to increase its capacity and store more water during wet years in Diamond Valley Lake, Southern California’s largest reservoir, which can hold about 260 billion gallons of water. “Sometimes tunneling is actually the most effective way to get from point A to point B,” said Deven Upadhyay, the MWD’s general manager.Speaking hypothetically, Upadhyay said, if engineers had another shot at designing and building the aqueduct now using modern technology, it’s hard to say if they would end up choosing the same route through Mt. San Jacinto or a different route around it. But the focus on minimizing cost might yield a similar route, he said.“Even to this day, it’s a pretty impressive design,” Upadhyay said.When people drive past on the I-10 in Cabazon, few realize that a key piece of infrastructure lies hidden where the desert meets the base of the mountain. At the tunnel’s exit point near San Jacinto, the only visible signs of the infrastructure are several concrete structures resembling bunkers. When the aqueduct is running, those who enter the facility will hear the rumble of rushing water. The tunnel’s west end was opened to a group of visitors in March, when the district’s managers held an event to name the tunnel in honor of Randy Record, who served on the MWD board for two decades and was chair from 2014 to 2018. Speaking to an audience, Upadhyay reflected on the struggles the region now faces as the Colorado River is sapped by drought and global warming, and he drew a parallel to the challenges the tunnel’s builders overcame in the 1930s. “They found a path,” Upadhyay said. “This incredible engineering feat. And it required strength, courage and really an innovative spirit.” “When we now think about the challenges that we face today, dealing with wild swings in climate and the potential reductions that we might face, sharing dwindling supplies on our river systems with the growing Southwest, it’s going to require the same thing — strength, courage and a spirit of innovation,” he said.

Officials to Test Water From Ohio Village Near Cold War-Era Weapons Plant After Newspaper Probe

Authorities in Ohio plan to test the water supply across a small village near a former weapons plant after a newspaper investigation published Friday found high levels of radioactivity in samples taken at a school, athletic field, library and other sites

LUCKEY, Ohio (AP) — Authorities in Ohio plan to test the groundwater supply across a village near a former weapons plant after a newspaper investigation published Friday found high levels of radioactivity in samples taken at a school, athletic field, library and other sites.However, The Blade in Toledo said its tests showed radioactivity levels 10 times higher than normal in water from a drinking fountain at Eastwood Middle School, 45 times higher than normal at the Luckey Library and 1,731 times higher than normal at a water pump near athletic fields.“We’ve got to get to the bottom of this,” said Lt. Col. Robert Burnham, commander of the U.S. Army Corps of Engineers’ Buffalo District, which oversees the cleanup.Nineteen of the 39 samples collected by the newspaper from well water across Luckey — at homes, businesses, and public places — showed radioactivity at least 10 times greater than what the federal government calls normal for the area, the newspaper said. The Blade hired an accredited private lab to conduct the testing.The radioactivity detected was primarily bismuth-214, which decays from the radioactive gas radon-222. Experts agree that high levels of bismuth-214 suggest high levels of radon are also present.Radon exposure is the leading cause of lung cancer in nonsmokers.The testing also found low levels of radioactive cobalt-60, a man-made isotope, in two wells. Experts called that finding extremely rare.Taehyun Roh, a Texas A&M University scientist who specializes in environmental exposures, said regulators should also conduct air and soil testing to assess the extent of the contamination and identify the source."Since this area likely has high radon levels, testing for radon in both air and water is advisable,” he wrote in an email. “A safe drinking water advisory should be issued, recommending the use of bottled water until further assessments and mitigation measures are in place.”The Corps of Engineers has long maintained that residential drinking water was not being contaminated by the removal work. Burnham and others said they still believe that to be true, citing thousands of their own soil samples.The state Environmental Protection Agency and Department of Health will lead the testing. In an email, Ohio EPA spokesperson Katie Boyer told the newspaper the contaminant levels in the public drinking water are still “within acceptable drinking water standards.” She said any concerns raised by the state testing would be addressed.The 44-acre industrial site — 22 miles (35 kilometers) south of Toledo — was long crucial to America’s nuclear weapons program. In the 1940s, farmland was replaced by a sprawling defense plant that produced magnesium metal for the Manhattan Project. In the 1950s, the plant became the government’s sole source of beryllium metal for nuclear bombs, Cold War missiles and Space Race products, including a heat shield for Project Mercury.“Things that happened generations ago are still affecting us,” said Karina Hahn-Claydon, a 50-year-old teacher whose family lives less than a mile from the site. “And that’s because the government didn’t take care of it.”Private drinking wells, unlike municipal systems, are not regulated, and responsibility for testing is left to owners. The Blade’s testing took place from April 2024 through January.Radioactivity has been linked to an increased risk of various cancers, including blood and thyroid cancers.Copyright 2025 The Associated Press.

UK spending watchdog censures water firms and regulators over sewage failings

Water companies have been getting away with failures to improve sewage works and overspending because of regulatory problems, a damning report by the government’s spending watchdog has found.Firms have overspent on infrastructure building, the National Audit Office (NAO) found, with some of these costs being added to consumers’ bills. The Guardian this week reported Ofwat and the independent water commission are investigating water firms for spending up to 10 times as much on their sewage works and piping as comparable countries.Bills in England and Wales are rising by £123 on average this year, and will go up further over the next five years, so that companies can fix ageing sewage infrastructure and stop spills of human waste from contaminating rivers and seas. Several water firms have complained to the Competition and Markets Authority because they want the regulator to allow them to increase bills even further.Only 1% of water companies’ actions to improve environmental performance, such as improving sewer overflows, have been inspected by the Environment Agency, the authors of the NAO report said. They also found there was no regulator responsible for proactively inspecting wastewater assets to prevent further environmental harm.The report, which audited the three water regulators, Ofwat, the Environment Agency, and the Drinking Water Inspectorate, as well as the Department for Environment Food and Rural Affairs, also found the regulators did not have a good understanding of the condition of infrastructure assets such as leaking sewers and ageing sewage treatment facilities as they do not have a set of metrics to assess their condition.Gareth Davies, the head of the NAO, said: “Given the unprecedented situation facing the sector, Defra and the regulators need to act urgently to address industry performance and resilience to ensure the sector can meet government targets and achieve value for money over the long term for bill payers.”Despite the huge costs of infrastructure, the water companies have moved slowly meaning that at the current rate, it would take 700 years to replace the entire existing water network, the report found. Regulatory gaps and a lack of urgency about replacing old and malfunctioning infrastructure has caused a “rising tide of risk” in the sector, which is contributing to increasing bills for customers, the report warned.It also criticised the lack of a national plan for water supply and recommended that Defra must understand the costs and deliverability of its plans, alongside the impact they would have on customers’ bills.Several of the issues raised by the NAO, including concerns about weak infrastructure, have come to the fore in the debate over the future of Thames Water, the country’s largest water company with 16 million customers. Thames, which is under significant financial pressure with almost £20bn in debt, needs to secure fresh investment within months. Questions over the state of Thames’s infrastructure and regulatory punishment it could face for its failures have dogged the process of winning fresh funds. Meanwhile, Ofwat has also rejected its requests to raise bills by as much as 59%, instead allowing a 35% increase over the next five years.The government set up the independent water commission (IWC) last year to investigate how the water industry operated and whether regulation was fit for purpose.Sir Geoffrey Clifton-Brown, the Tory chair of the Commons public accounts committee, said: “Today’s NAO report lays bare the scale of the challenges facing the water sector – not least the real prospect of water shortfall without urgent action.“The consequences of government’s failure to regulate this sector properly are now landing squarely on bill payers who are being left to pick up the tab. After years of under-investment, pollution incidents and water supply issues, it is no surprise that consumer trust is at an all-time low. Having not built any reservoirs in the last 30 years, we now need 10.skip past newsletter promotionSign up to Business TodayGet set for the working day – we'll point you to all the business news and analysis you need every morningPrivacy Notice: Newsletters may contain info about charities, online ads, and content funded by outside parties.

Defra and the regulators must focus on rebuilding public confidence and ensure the sector can attract the long-term investment it desperately needs.”An Environment Agency spokesperson said: “We recognise the significant challenges facing the water industry. That is why we will be working with Defra and other water regulators to implement the report’s recommendations and update our frameworks to reflect its findings.”An Ofwat spokesperson added: “We agree with the NAO’s recommendations for Ofwat and we continue to progress our work in these areas, and to contribute to the IWC wider review of the regulatory framework. We also look forward to the IWC’s recommendations and to working with government and other regulators to better deliver for customers and the environment.”A Defra spokesperson said: “The government has taken urgent action to fix the water industry – but change will not happen overnight. We have put water companies under tough special measures through our landmark Water Act.”Water UK, which represents the water companies, has been contacted for comment.

Water firms admit sewage monitoring damaging public trust

The industry says powers to self-monitor water quality should be handed back to the regulator.

Water companies should no longer be allowed to monitor their own levels of sewage pollution, the industry body has told the BBC exclusively.Instead they are proposing a new, third-party monitoring system to build consumer trust.The recommendation is part of a submission made to the UK government's independent review into the water sector.Campaigners have long complained the companies' self-reporting has prevented the true scale of pollution in UK water being revealed.A third-party system could add more pressure to the regulators, which have also been criticised for not holding the companies to account. A report from the National Audit Office is expected to say on Friday that the Environment Agency does not currently have enough capacity to take on any new monitoring.David Henderson, CEO of industry body Water UK, told the BBC: "We absolutely accept that self-monitoring is not helping to instil trust and so we would like to see an end to it, and in place of it a more robust, third-party system." As part of their permitting arrangements water companies are expected to regularly sample water quality to identify potential pollution, and submit this data to the Environment Agency in an arrangement known as "operator self monitoring". But there have been incidents of misreporting by water companies in England and Wales uncovered by the regulators, who said some cases had been deliberate.Southern Water was previously issued fines totalling £213m by the industry regulator (Ofwat) and the environmental regulator (the Environment Agency) for manipulating sewage data.In that case, there was unreported pollution into numerous conservation sites which caused "major environmental harm" to wildlife.The company later admitted its actions "fell short".Henderson added that the industry never asked to self-monitor, but that it was introduced in 2009 by the then Labour government to "reduce the administrative burden" on the Environment Agency (EA). In 2023, the BBC reported that EA staff were concerned that, due to funding cuts, the Agency was increasingly relying on water companies to self-report rather than carrying out its own checks on pollution from sewage. The current environment minister, Steve Reed, has promised to review the system, calling it the equivalent of companies "mark[ing] their own homework".But the National Audit Office (NAO), which reviews government spending, questioned the ability of the EA to take on any new monitoring. "Regulators need to address the fact that they currently have limited oversight over whether water companies are carrying out their work as expected. It is hard to see how they will achieve this without increased overall capacity," said Anita Shah, NAO Director of Regulation.It is expected to publish a full review of the regulation of the water sector on Friday. A Defra spokesperson told the BBC: "We are committed to taking decisive action to fix the water industry. The Water Commission's recommendations will mark the next major step [to] restore public trust in the sector."The government launched an independent water commission in October to review the sector and the way it is regulated. The public consultation closed on Wednesday with the findings expected in July. Water UK submitted a 200-page document of recommendations, including this call to end self-monitoring.The industry body also requested that water meters be universal across England and Wales to make bills fairer. At present about 60% of the population have a meter."The meter is just to ensure that people are paying for what they use as opposed to a flat rate of system where you can use virtually no water and pay the same as someone filling up a pool three times in a summer," said Henderson."This doesn't properly reflect the value of water and encourage people to conserve it in the way that we need," he added.

Cambodia Canal's Impact on Mekong Questioned After China Signs Deal

By Francesco Guarascio(Reuters) -Cambodia should share a feasibility study on the impact of a planned China-backed canal that would divert water...

(Reuters) -Cambodia should share a feasibility study on the impact of a planned China-backed canal that would divert water from the rice-growing floodplains of Vietnam's Mekong Delta, said the body overseeing the transnational river.After months of uncertainty, Phnom Penh last week signed a deal with China to develop the Funan Techo Canal when President Xi Jinping visited Cambodia as part of a tour of Southeast Asia.It was Beijing's first explicit public commitment to the project, giving state-controlled construction giant China Communications Construction Company (CCCC) a 49% stake through a subsidiary, but also linking Chinese support to the "sustainability" of the project.The Secretariat of the intergovernmental Mekong River Commission (MRC) that coordinates the sustainable development of Southeast Asia's longest river said it had so far received from Cambodia only "basic information" on the project."We hope that further details, including the feasibility study report and other relevant reports, will be provided," the Commission said in a statement to Reuters this week.That would be needed "to ensure that any potential implications for the broader Mekong Basin are fully considered," it added.The canal has already created concern among environmentalists who say it could further harm the delicate ecology of the Mekong Delta, which is Vietnam's major rice growing region and is already facing problems of drought and salination as result of infrastructure projects upstream. Vietnam is also a leading exporter of rice.On Friday, the Cambodian government said the canal would have minimal environmental impact and "aligns with the 1995 Mekong Agreement" which governs cooperation among riverine countries in Southeast Asia.The Mekong River, fed by a series of tributaries, flows some 4,900 kilometres (3,045 miles) from its source in the Tibetan plateau through China, Myanmar, Laos, Cambodia and Vietnam to the sea."Whether the Funan Techo Canal violates the 1995 Mekong Agreement depends on several factors, including its connection to the Mekong mainstream," the Commission said, offering additional guidance to Phnom Penh and other member states "to ensure compliance".Cambodia, Laos, Thailand and Vietnam are members of the MRC while China and Myanmar are dialogue partners.The Cambodian government did not respond to questions about whether it intended to share the requested documents.Vietnam's foreign ministry did not reply to a request for comment after the deal with China was signed, but the country has repeatedly asked Cambodia to share more information about the canal to assess its impact.Xi made no reference to the canal in his public statements in Phnom Penh but a joint communique issued at the end of his visit said China supported Cambodia in building the canal "in accordance with the principles of feasibility and sustainability".The deal signed by CCCC on Friday was for a 151.6 km (94.2 miles) canal costing $1.16 billion.However, the Cambodian government says on the canal's official website that the waterway would stretch 180 km and cost $1.7 billion at completion in 2028.The higher cost reflects a short section to be built by Cambodian firms as well as bridges and water conservation resources, the government told Reuters without clarifying who would pay for the bridges and water conservation.Cambodia's deputy prime minister said in May 2024 that China would cover the entire cost of the project, which was put at $1.7 billion.The canal is designed to link the Mekong Basin to the Gulf of Thailand in Cambodia's southern Kep province. Much of the Mekong's nutrient-rich sediment no longer reaches rice farms in the Delta because of multiple hydroelectric dams built by China upriver, a Reuters analysis showed in 2022.The project agreed with China is also different from the original plan as it is focusing on boosting irrigation rather than solely pursuing navigation purposes, said Brian Eyler, an expert on the Mekong region at U.S.-based think tank Stimson Center.The water diverted from the Mekong Delta "will be much more than previously described," said Eyler.(Reporting by Francesco Guarascio; additional reporting by Khanh Vu in Hanoi; Editing by Kate Mayberry)Copyright 2025 Thomson Reuters.
