A River ‘Died' Overnight in Zambia After an Acidic Waste Spill at a Chinese-Owned Mine

Saturday, March 15, 2025

KITWE, Zambia (AP) — Authorities and environmentalists in Zambia fear the long-term impact of an acid spill at a Chinese-owned mine that contaminated a major river and could potentially affect millions of people after signs of pollution were detected at least 100 kilometers (60 miles) downstream.The spill happened on Feb. 18 when a tailings dam that holds acidic waste from a copper mine in the north of the country collapsed, according to investigators from the Engineering Institution of Zambia. The collapse allowed some 50 million liters of waste containing concentrated acid, dissolved solids and heavy metals to flow into a stream that links to the Kafue River, Zambia’s most important waterway, the engineering institution said.“It is an environmental disaster really of catastrophic consequences,” said Chilekwa Mumba, an environmental activist who works in Zambia's Copperbelt Province.China is the dominant player in copper mining in Zambia, a southern African nation which is among the world’s top 10 producers of copper, a key component in smartphones and other technology.Zambian President Hakainde Hichilema called for help from experts and said the leak is a crisis that threatens people and wildlife along the Kafue, which runs for more than 1,500 kilometers (930 miles) through the heart of Zambia. Authorities are still investigating the extent of the environmental damage.An Associated Press reporter visited parts of the Kafue River, where dead fish could be seen washing up on the banks about 100 kilometers (60 miles) downstream from the mine run by Sino-Metals Leach Zambia, which is majority owned by the state-run China Nonferrous Metals Industry Group.The Ministry of Water Development and Sanitation said the "devastating consequences" also included the destruction of crops along the river's banks. Authorities are concerned that ground water will be contaminated as the mining waste seeps into the earth or is carried to other areas.“Prior to the 18th of February this was a vibrant and alive river,” said Sean Cornelius, who lives near the Kafue and said fish died and birdlife near him disappeared almost immediately. “Now everything is dead, it's like a totally dead river. Unbelievable. Overnight, this river died.”About 60% of Zambia's 20 million people live in the Kafue River basin and depend on it in some way as a source of fishing, irrigation for agriculture and water for industry. The river supplies drinking water to about five million people, including in the capital, Lusaka.The acid leak at the mine caused a complete shutdown of the water supply to the nearby city of Kitwe, home to an estimated 700,000 people. Attempts to roll back the damage The Zambian government has deployed the air force to drop hundreds of tons of lime into the river in an attempt to counteract the acid and roll back the damage. Speed boats have also been used to ride up and down the river, applying lime. Government spokesperson Cornelius Mweetwa said the situation was very serious and Sino-Metals Leach Zambia would bear the costs of the cleanup operation.Zhang Peiwen, the chairman of Sino-Metals Leach Zambia, met with government ministers this week and apologized for the acid spill, according to a transcript of his speech at the meeting released by his company. “This disaster has rung a big alarm for Sino-Metals Leach and the mining industry,” he said. He said it “will go all out to restore the affected environment as quickly as possible." Discontent with Chinese presence The environmental impact of China's large mining interests in mineral-rich parts of Africa, which include Zambia's neighbors Congo and Zimbabwe, has often been criticized, even as the minerals are crucial to the countries' economies. Chinese-owned copper mines have been accused of ignoring safety, labor and other regulations in Zambia as they strive to control its supply of the critical mineral, leading to some discontent with their presence. Zambia is also burdened with more than $4 billion in debt to China and had to restructure some of its loans from China and other nations after defaulting on repayments in 2020.A smaller acid waste leak from another Chinese-owned mine in Zambia's copper belt was discovered days after the Sino-Metals accident, and authorities have accused the smaller mine of attempting to hide it.Local police said a mine worker died at that second mine after falling into acid and alleged that the mine continued to operate after being instructed to stop its operations by authorities. Two Chinese mine managers have been arrested, police said.Both mines have now halted their operations after orders from Zambian authorities, while many Zambians are angry.“It really just brings out the negligence that some investors actually have when it comes to environmental protection,” said Mweene Himwinga, an environmental engineer who attended the meeting involving Zhang, government ministers, and others. “They don’t seem to have any concern at all, any regard at all. And I think it’s really worrying because at the end of the day, we as Zambian people, (it's) the only land we have.”Zimba reported from Lusaka, Zambia.Copyright 2025 The Associated Press.

Authorities and environmentalists in Zambia fear the long-term impact of an acid spill at a Chinese-owned mine that poisoned a major river and could potentially affect millions of people after signs of pollution were detected at least 100 kilometers downstream

KITWE, Zambia (AP) — Authorities and environmentalists in Zambia fear the long-term impact of an acid spill at a Chinese-owned mine that contaminated a major river and could potentially affect millions of people after signs of pollution were detected at least 100 kilometers (60 miles) downstream.

The spill happened on Feb. 18 when a tailings dam that holds acidic waste from a copper mine in the north of the country collapsed, according to investigators from the Engineering Institution of Zambia.

The collapse allowed some 50 million liters of waste containing concentrated acid, dissolved solids and heavy metals to flow into a stream that links to the Kafue River, Zambia’s most important waterway, the engineering institution said.

“It is an environmental disaster really of catastrophic consequences,” said Chilekwa Mumba, an environmental activist who works in Zambia's Copperbelt Province.

China is the dominant player in copper mining in Zambia, a southern African nation which is among the world’s top 10 producers of copper, a key component in smartphones and other technology.

Zambian President Hakainde Hichilema called for help from experts and said the leak is a crisis that threatens people and wildlife along the Kafue, which runs for more than 1,500 kilometers (930 miles) through the heart of Zambia.

Authorities are still investigating the extent of the environmental damage.

An Associated Press reporter visited parts of the Kafue River, where dead fish could be seen washing up on the banks about 100 kilometers (60 miles) downstream from the mine run by Sino-Metals Leach Zambia, which is majority owned by the state-run China Nonferrous Metals Industry Group.

Environmental Agency Denies Petition to Designate Big Hole River as Impaired by Nutrient Pollution

Montana’s environmental regulator has denied a petition to designate the Big Hole River as impaired by nitrogen and phosphorus

Montana’s environmental regulator has denied a petition to designate the Big Hole River as impaired by nitrogen and phosphorus, throwing a wrench in environmentalists’ efforts to put the blue-ribbon fishery on a “pollution diet.”Upper Missouri Waterkeeper and the Big Hole River Foundation contend that excess nutrients are creating regular summertime algal blooms that can stretch for more than a mile, robbing fish and the macroinvertebrate bugs they eat of the oxygen they need to thrive. The groups argue in the petition they sent to the Montana Department of Environmental Quality last month that an impairment designation would direct the agency to identify and work to reduce the river’s pollution sources in an effort to rebalance the river’s aquatic ecosystem.On April 14, about a month after receiving the 32-page petition, DEQ wrote that it “cannot grant” the group’s petition. The agency’s letter doesn’t quibble with the groups’ findings, which were detailed in a five-year data collection effort. Instead, the agency suggested that legislation passed in 2021 has tied its hands. “As a result of Senate Bill 358, passed during the 2021 Legislative Session … DEQ is unable to base nutrient assessment upon the numeric nutrient criteria,” the letter, signed by DEQ Director Sonja Nowakowski, reads. In an April 23 conversation with Montana Free Press, Upper Missouri Waterkeeper Executive Director Guy Alsentzer criticized the agency’s decision, arguing that it did not use the best available science and applied “illogical and disingenuous” reasoning in its denial. “EPA already took action and struck down Senate Bill 358 from the 2021 session,” Alsentzer said, referencing federal regulators’ oversight of state laws and rules governing water quality. “Numeric criteria are applicable.”A spokesperson for the EPA confirmed Alsentzer’s assertion, writing in an April 24 email to MTFP that numeric nutrient standards for nitrogen and phosphorus the agency approved a decade ago “remain in effect for Clean Water Act purposes” and will remain so “unless or until the EPA approves the removal of the currently applicable numeric nutrient criteria and approves revised water quality standards.”A DEQ spokesperson did not directly answer MTFP’s questions about what water quality standards DEQ is using to assess Montana waterways and determine whether permittees are complying with state and federal regulations.The agency wrote in an email that no permitted pollution sources under its regulatory oversight are discharging into the Big Hole, suggesting that its enforcement role is limited. The agency also wrote that an impairment designation is not required to implement water quality improvement projects such as creating riparian buffers, improving forest roads, or creating shaded areas. “Watershed partners may begin actively working on nonpoint source pollution reduction projects at any time,” DEQ spokesperson Madison McGeffers wrote to MTFP. “There is nothing standing in the way of starting work on these types of projects to improve water quality. In fact, the Big Hole River Watershed Committee is actively implementing its Watershed Restoration Plan with funds and support from DEQ Nonpoint Source & Wetland Section’s 319 program.”Alsentzer countered that a science-based cleanup plan and greater accountability will benefit the Big Hole regardless of whether nutrients are flowing into the river from a pipe or entering via more diffuse and harder-to-regulate channels.“You can’t get to that if you don’t recognize that you’ve got a problem we need to solve,” he said, adding that an impairment designation “unlocks pass-through funding to the tune of millions of dollars.”Addressing manmade threats to the Big Hole should be a priority for DEQ, given local communities’ economic reliance on a healthy river, he added.“It’s just a real tragic state of affairs when you have a blue-ribbon trout fishery in a very rural county that’s essentially having its livelihood flushed down the drain because we can’t get our agencies to actually implement baseline river protections (and) use science-based standards,” Alsentzer said. “When people try to do the work for the agency and help them, they’re getting told to go pound sand. I think that’s wrong.”Two years ago, Montana Fish, Wildlife and Parks biologists recorded historically low numbers of brown trout along some stretches of the Big Hole. Anglers and conservationists floated a number of possible contributing factors, ranging from pathogens and drought conditions to angling pressure and unmitigated pollution. Save Wild Trout, a nonprofit formed in 2023 to understand which factors merit further investigation, described the 2023 southwestern Montana fishery “collapse” as a “canary in the coal mine moment.”In response to the 2023 population slump, Gov. Greg Gianforte announced the launch of a multiyear research effort on Jefferson Basin rivers that FWP is coordinating with Montana State University. Narrative Standards For ‘Undesirable Aquatic Life’ DEQ’s letter to Upper Missouri Waterkeeper and the Big Hole River Foundation leaves open the possibility of a future impairment designation based on narrative water quality standards. After mentioning the 2021 legislation, Nowakowski wrote that the agency reviewed the submitted data “along with other readily available data, in consideration of the state’s established narrative criteria.”The letter goes on to outline the additional material petitioners would need to submit for the agency to evaluate an impairment designation using narrative criteria, which establish that surface waters must be “free from substances” that “create conditions which produce undesirable aquatic life.”In an April 22 letter, Upper Missouri Waterkeeper and the Big Hole River Foundation addressed the petition denial in two parts. First, the groups argued that numeric nutrient standards apply. Second, they resubmitted material — photos, emails, a macroinvertebrate report, and “Aquatic Plant Visual Assessment Forms” — to support an impairment designation under the looser narrative standards. “We encourage DEQ to do the right thing, use all available science to determine the Big Hole River impaired for nutrients, and commit to working with petitioners and other (stakeholders) in addressing the pollution sources undermining this world-class waterway and harming the diverse uses it supports,” the letter says. Alsentzer noted that he has set up a meeting with the EPA to discuss DEQ’s treatment of the petition and its description of applicable water quality standards.The dispute over numeric nutrient standards comes shortly after the Legislature passed another bill seeking to repeal them. Any day now, Gianforte is expected to sign House Bill 664, which bears a striking similarity to 2021’s Senate Bill 358. HB 664 has garnered support from Nowakowski, who described it as a “time travel” bill that will return the state to “individual, site-by-site” regulations in lieu of more broadly applicable numeric standards.

Supreme Court justices consider reviving industry bid to ax California clean car rule

The Supreme Court on Wednesday heard oral arguments in a case that could revive a bid by fuel producers to ax California’s clean car standards. The court was not considering the legality of the standards themselves, which ​​require car companies to sell new vehicles in the state that produce less pollution — including by mandating a significant share of cars sold to be electric or hybrid.  Instead, the Supreme Court was considering whether the fuel industry had the authority to bring the lawsuit at all. A lower court determined that the producers, which include numerous biofuel companies and trade groups representing both them and the makers of gasoline, did not have standing to bring the case. Some of the justices were quiet, so it’s difficult to predict what the ultimate outcome of the case will be. However, others appeared critical of the federal government and California’s arguments that the fuel producers do not have the right to bring a suit. Justice Brett Kavanaugh in particular noted that the Environmental Protection Agency (EPA) itself did not initially try to have the case tossed on that basis.  “Isn't that a tell here? I mean, EPA, as you, of course, know, routinely raises standing objections when there's even — even a hint of a question about it,” Kavanaugh said.  The fuel producers argued that while it was technically the auto industry that was being regulated, the market was being “tilted” against them as well by California’s rule, which was also adopted by other states. The EPA and California have argued that the fuel producers are arguing on the basis of outdated facts and a market that has shifted since the rule was first approved by the EPA in 2013.  The EPA needs to grant approval to California to issue such rules. The approval was revoked by the Trump administration and later reinstated in the Biden administration.  If the justices revive the currently dismissed case, lower courts would then have to decide whether to uphold the California rule — though the underlying case could eventually make its way to the high court as well.  Meanwhile, California has since passed subsequent standards that go even further — banning the sale of gas-powered cars in the state by 2035. That rule was approved by the Biden administration — though Congress may try to repeal it.

EPA fires or reassigns hundreds of staffers

The Environmental Protection Agency plans to fire or reassign more than 450 staffers working on environmental justice issues, it said Tuesday.Why it matters: The large-scale changes could effectively end much of the EPA's work tackling pollution in historically disadvantaged communities.It's part of the Trump administration's effort to vastly shrink the federal workforce. EPA has around 15,000 employees.Driving the news: EPA notified roughly 280 employees that they will be fired in a "reduction in force." Another 175 who perform "statutory functions" will be reassigned.The employees come from the Office of Environmental Justice and External Civil Rights, the Office of Inclusive Excellence, and EPA regional offices."EPA is taking the next step to terminate the Biden-Harris Administration's Diversity, Equity, and Inclusion and Environmental Justice arms of the agency," a spokesperson said.Between the lines: The firings will likely see challenges from congressional Democrats and the employees themselves.EPA had previously put many environmental justice staffers on administrative leave.Administrator Lee Zeldin, during a Monday news conference, defended the agency's broader efforts to cut environmental justice grant programs, arguing the money is ill-spent."The problem is that, in the name of environmental justice, a dollar will get secured and not get spent on remediating that environmental issue," he said.

EPA firing 280 staffers who fought pollution in overburdened neighborhoods

The Environmental Protection Agency (EPA) will fire 280 staffers who worked on tackling pollution in overburdened and underserved communities and will reassign another 175. These staffers worked in an area known as “environmental justice,” which helps communities that face a disproportionate amount of pollution exposure, especially minority or low-income communities.  The EPA has framed its efforts to cut these programs — including its previous closure of environmental justice offices — as part of a push to end diversity programming in the government. Supporters of the agency's environmental justice work have pointed out that Black communities face particularly high pollution levels and that the programs also help white Americans, especially if they are poor.  “EPA is taking the next step to terminate the Biden-Harris Administration’s Diversity, Equity, and Inclusion and Environmental Justice arms of the agency,” an EPA spokesperson said in a written statement.   “Today, EPA notified diversity, equity, and inclusion and environmental justice employees that EPA will be conducting a Reduction in Force,” the spokesperson said. “The agency also notified certain statutory and mission essential employees that they are being reassigned to other offices through the ‘transfer of function’ procedure also outlined in [the Office of Personnel Management’s] Handbook and federal regulations” The firings will be effective July 31, according to E&E News, which first reported that they were occurring. The news comes as the Trump administration has broadly sought to cut the federal workforce. The administration has previously indicated that it planned to cut 65 percent of the EPA’s overall budget. It’s not clear how much of this will be staff, though according to a plan reviewed by Democrat House staff, the EPA is considering the termination of as many as about 1,100 employees from its scientific research arm.  Meanwhile, as part of their reductions in force, other agencies including the Department of Health and Human Services and the Department of Veterans Affairs have fired tens of thousands of staffers. The EPA is smaller than these agencies, with a total of more than 15,000 employees as of January.  Nearly 170 environmental justice staffers were previously placed on paid leave while the agency was “in the process of evaluating new structure and organization.”
