Takeaways From AP's Report on How Duck Valley Indian Reservation's Water and Soil Is Contaminated

Monday, September 9, 2024

OWYHEE, Nev. (AP) — The Shoshone-Paiute Tribes of the Duck Valley Indian Reservation have long grappled with contaminants embedded in the land and water. For decades, the tribes suspected that widespread illness and deaths from cancer are tied to two buildings owned and operated by the U.S. Bureau of Indian Affairs. Fuel, herbicides and other chemicals spilled onto the dirt floors of the now-shuttered or demolished structures.Earlier this year, the BIA discovered a decades-old document with a passing mention of Agent Orange that suggests the government might have been more involved in contaminating the land than previously known, this time around the irrigation canals. The community is still waiting to get answers. Sacred land, now contaminated Owyhee is the sole town on the reservation where snow-capped mountains loom over a valley of scattered homes and ranches, nearly 100 miles (161 kilometers) from any stoplights. Bookended by deep Nevada canyons and flat Idaho plains, the valley is home to “Sho-Pais,” whose ancestors were confined there by the federal government.

The Shoshone-Paiute Tribes of the Duck Valley Indian Reservation have long grappled with contaminants in the soil and water

OWYHEE, Nev. (AP) — The Shoshone-Paiute Tribes of the Duck Valley Indian Reservation have long grappled with contaminants embedded in the land and water.

For decades, the tribes suspected that widespread illness and deaths from cancer are tied to two buildings owned and operated by the U.S. Bureau of Indian Affairs. Fuel, herbicides and other chemicals spilled onto the dirt floors of the now-shuttered or demolished structures.

Earlier this year, the BIA discovered a decades-old document with a passing mention of Agent Orange that suggests the government might have been more involved in contaminating the land than previously known, this time around the irrigation canals. The community is still waiting to get answers.

Sacred land, now contaminated

Owyhee is the sole town on the reservation where snow-capped mountains loom over a valley of scattered homes and ranches, nearly 100 miles (161 kilometers) from any stoplights. Bookended by deep Nevada canyons and flat Idaho plains, the valley is home to “Sho-Pais,” whose ancestors were confined there by the federal government.

For generations, the legacy and livelihood of residents have centered around raising cattle year-round. Many of the 1,800 or so residents still use the same medicinal plans and practice the same ceremonies as their relatives buried under them.

Representatives from the BIA and the U.S. Environmental Protection Agency visited the reservation as recently as Aug. 7 to talk about the contamination and review the report that mentioned Agent Orange. Action can't come soon enough for tribal members who say the federal government's past cleanup attempts have lacked urgency and direction.

“People are dying. And I don’t know what they’re waiting for,” said tribal Chairman Brian Mason.

First spills, then potential sprays

Historically, most of the environmental dangers at Owyhee have been traced to two BIA buildings that have since closed or been demolished.

Back in 1985, at the now-abandoned irrigation shop, some 8,000 gallons of heating oil leaked from a pipeline next to a two-lane highway that acts as the area's main road. Samples taken from sump, soil and floor drains around the building revealed a mix of the hazardous chemicals that were stored inside, including waste oil, arsenic, copper, lead and cadmium, along with the two herbicides that make up Agent Orange.

Racheal Thacker, a pesticides and solid waste technician with the tribes, said residents at the time were likely unaware of the dangers related to handling the chemicals stored there. Back then, she said, the workers employed by the BIA didn’t have the expertise or resources to identify pollutants in the ground.

In 1995, the EPA ordered the BIA to stop discharging gasoline, batteries and other fluids onto the dirt floor of the maintenance building, saying the practice was improper, threatened the groundwater supply and could endanger tribal members’ health. The disposal practice had long-lasting effects. The building has since been demolished and is fenced off.

In its statement to the AP, the BIA said it has extensively studied the soil and groundwater on the reservation since 1999 and cleaned up wells used for drinking water. The agency also said any petroleum in the soil is safe and it’s working with the tribe on other remedial actions.

Link between toxins and deaths from cancer

To the community, there's a clear link between past contaminants and the pronounced number of cancer cases and other illnesses.

Mason validated those beliefs in an announcement earlier this year. He stood at a podium and declared — without caveats — that the BIA further poisoned the tribes' land. Agent Orange chemicals were sprayed extensively by the canals, he said, and demanded the government take quick action.

Health experts say it’s nearly impossible to say with certainty that the environment factored into cancer diagnoses and deaths — especially without robust data.

Fish Kill at Clear Lake Reveals a Seven-Foot Sturgeon Surprise 

A problem lake was doing pretty well this year. Then came a series of unfortunate water-quality events. The post Fish Kill at Clear Lake Reveals a Seven-Foot Sturgeon Surprise  appeared first on Bay Nature.

(Courtesy of Luis Santana)As Luis Santana motored out onto Clear Lake this August, it seemed at first like a normal summer day out on the water: warm air, cloudy skies, and the wide lake waters full of what seemed like bubbles from the waves.  “Then I stopped, and I was like, Oh my god,” Santana, a fisheries biologist with the Robinson Rancheria tribe, recalls. Those weren’t bubbles; they were millions of dead threadfin shad, and others. “I saw literally every species of fish found in the lake,” except for the Clear Lake tule perch, Santana says. The measurements he took that day revealed what likely killed them: a near-total lack of oxygen in the lake. The fish had, essentially, suffocated. Amid the silver-lined shores, one fish washed up that no one had known to be a resident: a dead seven-foot-long white sturgeon. It was Clear Lake’s first on record. No one knows for sure how it got into the waters, but Santana thinks it died with the shad. White sturgeon (Acipenser transmontanus), the biggest freshwater fish in North America, live in the Bay-Delta. They became a candidate for listing as a threatened species under the California Endangered Species Act after a 2022 harmful algal bloom that killed hundreds of them.  Big ’un: A white sturgeon—in Clear Lake? CDFW says the average sturgeon caught in the Delta these days is about 3.6 feet long, and it is rare to encounter fish larger than 6.5 feet long in California. This one was seven feet. (Courtesy of Luis Santana)This fall’s fish die-off is the lake’s largest since at least 2017, according to records from the Big Valley Band of Pomo Indians. And it is yet another environmental black mark for a lake—California’s largest freshwater body—that has been consistently troubled by poor water quality. Now, scientists are uncovering the exact cause of the die-off—and analyzing the sturgeon for more answers. For Angela DePalma-Dow, a lake scientist and executive director of the Lake County Land Trust, the event reminds her: “There’s so much we can learn from Clear Lake.”  As a five-year-old, Santana spent every summer day swimming in Clear Lake. That’s a distant dream now. The summer lake—despite the name—is rarely clear; more often, it’s clouded dirty green as harmful algal blooms take over the waters. Sometimes, Santana thinks the water smells like sewage. “I don’t think my kids have ever swam in Clear Lake,” Santana says.  Fish die-offs and fish kills are a consequence of these impaired conditions, especially the frequent harmful algal blooms (HABs), during which algae decompose and strip the water of oxygen (while also filling the water with cyanotoxins). The Big Valley Band of Pomo Indians has tracked harmful algal blooms in Clear Lake since 2014. The program started after five years of “thick, noxious blooms covering [Clear Lake’s] surface” (as the tribe writes in a history of the program) and no regular monitoring from the state, despite recommendations from the California Office of Environmental Health Hazard Assessment. “We just needed to have more data,” says Sarah Ryan, the environmental director at the Big Valley Band of Pomo Indians.  “It seems like they have fish kills every year,” says Ben Ewing, who studies the endemic Clear Lake hitch, a large minnow, at the California Department of Fish and Wildlife. “I lost track with how many.” In 2017, the state Legislature formed a committee to restore the lake, citing high mercury levels, dangerous contaminants in fish, and the regular HABs; to date, it has led to tens of millions in state funding for research, restoration, and education projects on Clear Lake, including helping sustain water quality monitoring cut by the state during the Covid pandemic.  Cyanobacteria bloom at Redbud Park, in Clear Lake’s southeast arm, in July 2020.

(Courtesy of Big Valley Band of Pomo Indians)This die-off, Ewing says, caught lake-watchers off guard because 2025 seemed like the year Clear Lake might escape a fish kill. The characteristic pea soup of harmful algal blooms had been noticeably absent. Instead, the cause was likely a perfect storm of other conditions, says Ewing. “Everything had to line up correctly for this to happen,” he says.  Two bountiful water seasons laid the ground for it, DePalma-Dow explains. Fish populations—especially nonnative bait fish like shad—boomed with the increased water, which also meant some fish naturally died. She speculates that as their bodies decomposed, they stripped oxygen from the water column. Then, this fall, heavy winds came and distributed the low-oxygen water throughout the water column. A series of cloudy mornings arrived, during which the lake’s aquatic plants couldn’t respire oxygen back into the water. So more fish likely died, triggering oxygen levels to further plummet. Eventually, conditions became fatal for all species of fish. Santana says he measured “basically zeroes on every level” for dissolved oxygen through the water column. DePalma-Dow says this process is just the lake self-regulating, as fish populations outstrip the oxygen available. “This is totally not surprising for a lake cycle event,” she says. “This is a big, huge, natural system.” Santana blames human disturbance for the die-off. “We took away all the habitat that could potentially negate any of these effects,” he says. Clear Lake has lost up to 90 percent of its wetlands, he says, and creeks that might once have provided an infusion of oxygen-rich water into the lake now run dry in May and June. “There’s just so many things we’re taking and taking and not giving back,” he says.  A satellite image of Clear Lake during a May 2024 algal bloom. The emerald color doesn’t tell you whether toxins are present, though. That requires water sampling, which the Big Valley Band of Pomo Indians EPA has been doing since 2014. (Sentinel-2 satellite, via the Copernicus browser)In lieu of those natural processes, technological solutions are being considered: Researchers from UC Davis are exploring installing oxygenators in Clear Lake that could trap nutrients in the sediment under a thin layer of oxygen, theoretically reducing the number of harmful algal blooms—and, possibly, keeping oxygen levels higher so more fish can breathe. “That would be one of the hopeful outcomes,” says DePalma-Dow. Neither the state nor county put out a press release about the die-off, Ryan notes. “It’s always better if you can anticipate the questions and try to get information out.” For now, those living by the lake watch (and smell) the dead fish decompose. “There’s really no post support,” she says.  The August die-off on Clear Lake silvered the shoreline. It claimed fish of “literally every species,” says Luis Santana, a Robinson Rancheria fisheries biologist. (Larger fish on shore courtesy of Luis Santana; silvery shoreline by Shawna McEwan; closeup by Sophia Zesati) Fish populations will likely recover, scientists say. Many fish probably survived, in nooks and crannies. With good winter rains, they can breed and repopulate the waters by spring. This die-off is just another challenge for a beleaguered lake.  As for the sturgeon? USGS scientists were trying to figure out how old it was, and hoping to answer when it got to the lake, but the government shutdown has since paused their work. And they cannot answer questions about their research until the shutdown ends. Santana’s observations of the sturgeon showed it was a female with eggs. For now, the giant fish is a reminder of the treasures that may hide in Clear Lake’s murky waters. “Every year is a mystery and surprise,” DePalma-Dow says.

Millions of households face jump in water bills after regulator backs more price rises

Competition watchdog agrees requests from Anglian, Northumbrian, Southern, Wessex and South East to raise household billsBusiness live – latest updatesWater bills for millions of households in England will increase by even more than expected after the competition regulator gave the green light for five water suppliers to raise charges to customers – but rejected most of the companies’ demands.An independent group of experts appointed by the Competition and Markets Authority (CMA) decided provisionally to let the companies collectively charge customers an extra £556m over the next five years, it said on Thursday.

Water bills for millions of households in England will increase by even more than expected after the competition regulator gave the green light for five water suppliers to raise charges to customers – but rejected most of the companies’ demands.An independent group of experts appointed by the Competition and Markets Authority (CMA) decided provisionally to let the companies collectively charge customers an extra £556m over the next five years, it said on Thursday. That was only 21% of the £2.7bn that the firms had requested.The five companies – Anglian, Northumbrian, Southern, Wessex and South East – together serve 14.7 million customers. The changes will add 3% on average to those companies’ bills, on top of the 24% increase previously allowed.The companies appealed to the CMA in February for permission to raise bills by more than allowed previously by the industry regulator, Ofwat. They argued they needed more to meet environmental standards.Water bills have become the subject of significant political controversy in recent years in the UK amid widespread disgust over leaks of harmful sewage into Britain’s rivers and seas.Emma Hardy, the water minister, said: “I understand the public’s anger over bill rises – that’s why I expect every water company to offer proper support to anyone struggling to pay.“We’ve made sure that investment cash goes into infrastructure upgrades, not bonuses, and we’re creating a tough new regulator to clean up our waterways and restore trust in the system.”English and Welsh water companies are mostly privately owned, but the prices the local monopolies can charge customers are regulated by Ofwat over five-year periods. Ofwat in December said average annual household bills could rise by 36% to £597 by 2030 to help pay for investment.Ofwat said the companies could spend £104bn in total, paid by consumers.The allowed bill increases stopped well short of the water companies’ requests. The CMA said the expert panel had largely reject companies’ funding requests for new activities and projects beyond those agreed by Ofwat. However, the panel did allow more money for returns to investors, to reflect sustained high interest rates since the bills increases were approved.Anglian Water, serving the east of England and Hartlepool, asked for the average annual household bill to rise to £649 – a 10% increase – but was granted only £599, or 1%. Northumbrian, mainly in north-east England, asked for £515, or 6%, and was given £495, also 1%.South East Water, which only provides drinking water and not sewage services in several home counties, asked for an 18% increase to £322, but was allowed 4% to £286. Southern Water, on England’s south-east coast, asked for a 15% increase to £710. That would have been the highest bill in England and Wales, but it was allowed only a 3% increase to £638.Wessex Water in south-west England asked for an 8% increase to £642, and was granted the biggest proportional increase on appeal of 5% to £622.The CMA and other regulators have faced pressure from the Labour government to put more focus on economic growth. The chancellor, Rachel Reeves, this year appointed former Amazon boss Doug Gurr to lead the CMA.Kirstin Baker, the chair of the group that decided on the appeals, said: “We’ve found that water companies’ requests for significant bill increases, on top of those allowed by Ofwat, are largely unjustified.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 information about charities, online ads, and content funded by outside parties.

Mike Keil, chief executive of the Consumer Council for Water, which represents consumers, said “further increases will be very unwelcome”, and questioned whether the CMA should have allowed higher returns for investors.“There is a danger the customers of these companies will end up paying more, without seeing any additional improvements in return,” he said.Environmental groups have questioned why companies are allowed to return cash to shareholders while continuing to pollute Britain’s rivers and seas. James Wallace, chief executive of River Action, a campaign group, said: “Once again, water bill payers are forced to shoulder the cost of decades of failure.“Millions of households in England face higher bills while rivers continue to suffer from mismanagement by privatised water companies. In 2024 alone, four of these five companies were responsible for at least 1.4m hours of sewage discharges into rivers and seas – a stark illustration of ongoing environmental harm.”The CMA group’s decision will also be carefully considered by Thames Water, Britain’s biggest water company with 16 million customers. Thames also appealed initially but has agreed to pause it while the utility and its creditors negotiate with Ofwat over a restructuring plan to try to cut its debt burden and prevent it collapsing into temporary government control.Thames is still considering a request for a further £4bn. People close to Thames Water had criticised Ofwat’s approach to the price determination, arguing that the utility needed much more cash to turn around its performance on pollution.The best public interest journalism relies on first-hand accounts from people in the know.If you have something to share on this subject you can contact the Business team confidentially using the following methods.Secure Messaging in the Guardian appThe Guardian app has a tool to send tips about stories.

South Africa’s Coast Is Rising—And Scientists Have a New Explanation Why

Human water management contributes to sinking land across the globe, and it may also be responsible for an unexpected rise

October 7, 20254 min readSouth Africa’s Coast Is Rising—And Scientists Have a New Explanation WhyHuman water management contributes to sinking land across the globe, and it may also be responsible for an unexpected riseBy Avery Schuyler Nunn edited by Sarah Lewin FrasierLand rising along South Africa’s coast may be closely tied to humans’ use of water. For decades geologists thought the slow rise of South Africa’s southern coast was driven by forces deep below—buoyant plumes of molten rock ascending through Earth’s mantle and heaving the crust upward over millions of years. But now satellite data and precise GPS measurements are tilting such assumptions off their axis. A study in the Journal of Geophysical Research: Solid Earth suggests this land rise may have less to do with deep tectonic forces and more to do with missing groundwater just under our feet.Human activity has long been depleting South Africa’s groundwater. In 2018, after grappling with severe droughts for years, the country came close to a full-blown water emergency when Cape Town was nearly the world’s first major city to literally run out of water—a scenario dubbed “Day Zero.” For several months that year the city’s residents faced the very real prospect of having to regularly queue for critically limited water supplies, an outcome staved off only by timely rainfall and intensive water-saving campaigns. The extreme shortage resulted from a combination of climate change and unsustainable water use, which drained surface reservoirs and placed mounting pressure on aquifers across the region.The recent study hypothesizes that the ground, once compressed by the sheer weight of the surface water and groundwater above it, is now expanding like a foam mattress relieved of pressure. Using GPS and satellite gravity data from between 2000 and 2021, the researchers detected a roughly six-millimeter rise in the land surface—a shift that coincides with humans’ depletion of South Africa’s water reserves and periods of drought.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.“Sometimes the first explanation isn’t necessarily the right one,” says University of Bonn geodesist Christian Mielke, the study’s lead author. “Perhaps it isn’t plate tectonics after all.”That misunderstanding, not necessarily the rising land itself, may be the most striking thing about South Africa’s situation. What was once chalked up to the slow churning of Earth’s mysterious and inaccessible interior may instead reflect human activity, especially our management—or mismanagement—of water.“The presence of water, either as ice and snow on the land surface or as groundwater below, and the removal of that water are intimately tied to the deformation of the ground’s surface,” says Stanford University geophysicist Rosemary Knight. In most places around the globe, this process usually leads to sinking, called land subsidence, to fill the gap.But in South Africa, the new study suggests, that tie between water and land movement shows up in a surprising way. During the rainy season, rivers and reservoirs fill, adding weight that presses the crust down. In the dry months, much of that water either evaporates or gets pumped away, and the land rebounds upward. Over time the long-term loss of groundwater tips the balance toward uplift rather than sinking.This “seasonal breathing” is the giveaway that the cause is probably not solely a mantle plume. If molten rock were pushing upward, the motion would be steady, not tied to rainfall cycles. The expansion, if verified, could be yet another example of the ways human water use is reshaping the planet.From 1945 to 1970 more than 13,000 square kilometers of California’s San Joaquin Valley, once hailed as a “land of milk and honey” for Dust Bowl migrants, sank by at least 30 centimeters—and in some places by nearly nine meters. The San Joaquin sinking has only sped up since then, and parts of the valley drop more than 30 centimeters a year during severe droughts. On average, the pace has accelerated by 70 percent from the mid-20th century.Something similar is happening to the Chesapeake Bay, which, with its sweeping estuaries and lush tidal wetlands, is one of the U.S. East Coast’s most ecologically significant regions. Here land subsidence—driven by both groundwater extraction from aquifers and the lingering effects of ancient glacial shifts—is accelerating flood risk and relative sea-level rise. Satellite data, tide gauge records and projections from the Intergovernmental Panel on Climate Change suggest that by 2100 the combination of subsidence and sea-level rise could inundate up to 1,100 square kilometers of the Chesapeake Bay’s coastline.Mielke notes that such findings highlight the complexity of the planet’s response to human-induced environmental change. The consequences are still gradually being uncovered, and the implications may be profound. As climate change accelerates, land movements could exacerbate other challenges, especially in coastal areas with rising seas.To monitor such hidden shifts on a global scale, scientists use the GRACE satellite mission (Gravity Recovery and Climate Experiment) to detect changes in Earth’s mass by measuring minuscule variations in gravity. Because water has weight, depleting or replenishing groundwater subtly alters the planet’s gravitational field, which GRACE can detect from orbit.Knight and other researchers are looking for ways to keep land from shifting on such a vast scale by maintaining a careful balance. “Basically you get subsidence when water out exceeds water in,” Knight says. “And for water in, the term that’s used is ‘recharge.’”Some recharge happens naturally as rain or snowmelt soaks into the soil, but this precipitation isn’t enough to offset decades of groundwater extraction and current demand. That’s why places such as California are now turning to managed aquifer recharge: strategically spreading excess surface water (such as winter floodwaters) across land where it can percolate into the ground and rebuild depleted reserves, or injecting water directly into aquifers. Estimates suggest there is space underground for a total amount of water 30 times the volume of California’s Shasta Lake, enough to begin reversing the land’s descent.As Knight puts it, the solution can’t be about just cutting back on groundwater pumping. It must involve replenishment: restoring water to the ground from which it was drawn.It’s Time to Stand Up for ScienceIf you enjoyed this article, I’d like to ask for your support.

The Great Divide

Twenty minutes outside of Visalia, amidst the seemingly endless rows of citrus trees, Yolanda Cuevas packs enchiladas with shredded chicken for her husband Benjamin, their adult daughters and two teenaged grandchildren in her modest single-story home. Their house is the first one off the main drag, one of 83 lining the two crumbling roads that comprise the tiny town of Tooleville. Yolanda must wash the tomatoes for the salsa first in the sink and then again with a splash of clean water from a 5-gallon jug. The process is arduous, and though she’s resigned to do it, she’s not happy about it. Along with Tooleville’s several hundred other residents, Yolanda’s family has survived on bi-weekly delivery of water to their homes for the past 12 years. It’s an annoyance for the family, and it’s expensive for the State of California, which has been paying for the replacement water since the discovery of Chromium-6 (the same chemical featured in Erin Brokovich) in the water. The simpler solution would be to consolidate the town’s water system with that of its larger, affluent neighbor to the west, Exeter. And for this purpose, Yolanda has become a reluctant activist, attending community meetings in Tooleville and lobbying for consolidation at Exeter’s city council meetings under the expert guidance of Pedro Hernandez, an organizer with the Leadership Counsel. While Exeter has resisted the consolidation since it was first proposed, organizers like Pedro feel that this could be the year Exeter finally succumbs to the growing community pressure and brings Tooleville into the fold. The decision will echo around the Central Valley and across the state, as hundreds of similar community water systems find themselves in a nearly identical predicament.
