Flint switched back to using water from Detroit in October 2015, and is now adding extra phosphates to that water to help reduce lead levels. Moreover, the EPA’s regulations only require water suppliers to take corrective action if 10 percent or more of older homes in their service area have lead levels above the standard. Roni Dengler is a 2017 AAAS mass media science & engineering fellow. The people of Flint, Michigan have been drinking lead-tainted water for more than a year since the city switched its water source from Detroit's Lake Huron to the Flint River. Curt Guyette, an investigative reporter with the Michigan branch of the ACLU who helped expose the lead crisis in Flint, profiled Walters in 2014 for a documentary on the city’s growing water problems. Subscribe to ‘Here's the Deal,’ our politics newsletter. "A lot of work still needs to be done to better understand the origins of this manmade disaster," Edwards says. In a cost-cutting move in 2014, the struggling city switched from Detroit’s water system to the Flint River. Since April, 2014, the source for the Flint drinking water has been the Flint River. “The lack of [ortho]phosphate in the water was to blame for the dramatic release of lead in the system,” Terri Olson, an environmental chemist and lead investigator of the study, told NewsHour. Left: Meanwhile, London, Ontario — like Flint — had received its water from The Great Lakes and had not treated its supply with orthophosphates. Both sources were treated with chlorine disinfectant, but health concerns arose within months of the switch. As Flint River water contacts lead, particularly in areas where water is stagnant, it leaches into the water supply inside homes and businesses. Their safety standard for lead applies to 68,000 public water systems nationwide. Dec 20 Guyette says that on his travels across the country, he's encountered many Americans who now know and worry about lead in their own drinking water. "It kind of changes your perception of how to solve these problems," Edwards says. The same goes for lead pipes. But as I continued to film with local residents, I was struck by how little the state seemed to be doing in response. “There’s no law that mandates maximum levels of lead in any tap in the United States,” Edwards said. Flint switched back to the Detroit water system in October 2015, but public health effects from lead exposure prompted emergency declarations … But these measures amount to just a "band-aid," according to Edwards. Overall, Olson’s team suspects that lead accounted for 30.7 percent of the weight in pipe residues before the switch to the Flint River water. Cookie Policy Haizhou Liu, an environmental engineer at the University of California at Riverside who studies corrosion and water quality, praised the study's "careful sampling," and said it shows how crucial phosphates are to controlling corrosion in water systems. Flint water crisis, public health crisis (April 2014–June 2016) involving the municipal water supply system of Flint, Michigan, which resulted in residents being exposed to dangerous levels of lead. WASHINGTON – Nearly four years after an emergency was declared over lead contamination in Flint's drinking water, the Trump administration on … “Corrosion control is an important band-aid that allows us to reduce the risk from the lead pipes for consumers,” said Marc Edwards, an environmental engineer at Virginia Polytechnic Institute who helped uncover the Flint water crisis. Why? Using samples taken by Walters in January 2015 and sections of the iron pipe that connected Walters' house to the lead service pipe, Edwards was able to pinpoint the contamination patterns. They calculated 36 micrograms of lead per liter of water — more than twice the amount allowed by the EPA — flowed into homes over the course of the 1.5-year-long crisis. People outside the government who were veterans of the D.C. water contamination and coverup helped blow the whistle in Flint. The absence of a water treatment — called orthophosphate — was a major contributor to lead contamination of Flint, Michigan’s water supply, scientists confirmed recently in Environmental Science and Technology Letters. Dr. Mona Hanna-Attisha testifies about lead contamination of the Flint, Mich., water supply during a U.S. House hearing in 2016. Rick Snyder's pledge to drink Flint's water for 30 days. Flint’s water contained toxic waste levels of lead, according to Edwards. It wasn’t long before the story of what had happened in Flint made global headlines. Olson and her colleagues at the University of Michigan in Ann Arbor, just 50 miles south of Flint, wanted to help. Accumulated lead on the pipes can fall off into the water over time even without changes to the water supply, such as the interruption of corrosion control in Flint. But, we now know as long as lead paint is there, it’s a hazard, Edwards said. Flint’s water troubles began in April 2014 when the city traded a corrosion-controlled water source — the Detroit River managed by the Detroit Water and Sewage Department — for a non-controlled one, the Flint River. The inner side, the one exposed to water, looked like Swiss cheese. The pipes are a reservoir of lead that can readily detach and pose a hazard to people, Edwards said. The team concludes that that avoiding lead contamination may require far more work than some think—and may even necessitate a nationwide overhaul of America’s outdated plumbing. It accumulated even more toxins from the lead pipes. For a new report, published yesterday in the journal Environmental Science and Technology, Edwards' team returned to “ground zero” and used chemical analysis of water samples to see just how deep the contamination in Walters’ home ran. Water from the Flint River was found to be highly corrosive to the lead pipes still used in some parts of the city. But in summer 2014, that changed. And according to the most recent tests, Flint's water is still undrinkable. FLINT, MI -- Tests show water leaving Flint's treatment plant is lead free, but by the time it reaches the tap, it sometimes has elevated levels of lead, and here's why. Dec 18 Roni Dengler After Flint River water began flowing, corrosive water caused lead to leach from joints, pipes and fixtures, causing a spike in toxic lead levels in the blood of Flint children and other residents. However, tests have shown Flint's tap water has improved greatly since the depths of the water crisis. However, tests have shown Flint's tap water has improved greatly since the depths of the water crisis. For 50 years, Flint had purchased its water from Detroit, its neighbor 70 miles to south. Terms of Use Additionally, about half of the service lines to homes in Flint are made of lead and because the water wasn't properly treated, lead began leaking into the water supply, in addition to the iron. The standard also doesn’t apply to private water systems like wells and springs. Subscribe to Here’s the Deal, our politics newsletter for analysis you won’t find anywhere else. When Michigan officials switched water sources for Flint, it introduced iron and lead into the water supply . An unknown number of children in Flint, Michigan, were exposed to dangerous amounts of lead in their drinking water because of a cheapskate decision to switch the city's water source in 2014. An 11-year-old changed election results on a replica Florida state website in under 10 minutes, Read Running tap water is seen in Flint, Michigan on May 4, 2016. For decades, the pipes that brought water to LeAnne Walters’ house did their job unnoticed and safely. This lead was the source of the initial contamination, Edwards says. The attorney general alleged Veolia gave Flint bad advice, and did not help it to prevent its lead crisis by pushing harder for safeguards against corrosion or a switch to a different water supply. Why is lead leaching into the water? However, in 2014, the cash-strapped city decided to end its agreement with Detroit and start pulling water from the Flint River until a new aqueduct was built. The crisis arose after Flint, under control of a state-appointed emergency manager, switched its water source from Detroit to the Flint River to save money in … Beyond the lab bench, she acted as editor-in-chief for a graduate student-run blog Science Buffs and co-organized several science and science communication symposiums, including the upcoming ComSciCon Rocky Mountain West. But the problem extends further. Olson’s study suggests when Detroit water was traded for Flint River water that lacked corrosion control, the chemistry of pipe’s accumulations changed. Today she says the water … Tests later revealed elevated levels of lead in the water coming from the river. The Black Lives Matter group said African-Americans, especially those in rural and poor areas, have long been denied equal access to clean drinking water. Definitively solving the lead pipe crisis will require more drastic efforts than just replacing existing pipes—it will require an expensive, time-consuming rehaul of the city’s entire plumbing system. "There's just a very severe lack of trust," says Guyette about Flint residents’ current relationship with both their water supply and their government officials. Olson’s team found enrichment of these two metals on Flint’s pipes relative to other cities. Another engineering failure that occurred during the Flint water crisis was a failure of the Lead and Copper Rule (LCR). What officials didn't seem to anticipate was the effect that the slightly more acidic water of the Flint River would have on the city's pipes. Residents began to complain, and elevated levels of lead were found in some children. Lead contamination is the most troubling in a series of water problems that have plagued Flint since the summer of 2014. Vote Now! "The crisis in Flint is not an isolated incident. Flint residents used bottled water for drinking and other household needs for more than a year. The team used a high-tech sorter — an inductively coupled plasma mass spectrometer — that can detect trace amounts of metals to precisely measure the amounts of lead, aluminum, magnesium, iron and other metals in samples scraped from the pipes. Yet, more than 150,000 public water systems exist in the country. Advertising Notice The root cause of the Flint lead crisis was corrosion, the new study confirms. About half of the service lines to homes in Flint are made of lead and because the water wasn't properly treated, lead began leaching into the water supply, in addition to the iron. On Tuesday, Governor Rick Snyder declared a state of emergency due to lead in the water … Without getting into the details of this rule, Flint had failures of the LCR that they did not report initially. It was patchy. "What this study does is only add to the evidence of how widespread the concern should be," he says. After meticulously sampling her house’s water and testing it with at-home testing kits, Walters discovered that it had lead levels far higher than those considered safe. Ben Panko is a staff writer for Smithsonian.com, Continue Mays did know one thing about her symptoms: They began after Flint, Michigan’s water supply was switched from the Detroit River to the Flint River in April of that year. On April 25, 2014 officials from Flint, Michigan switched the city’s water supply to the Flint River as a cost-cutting measure for the struggling city. Suddenly, Walters found that the water spewing out of her faucets was discolored and foul-tasting; her son would come out of the bath with alarming rashes. The outcome of these side-by-sides was unexpected. That led to residents' water being tainted with lead, causing one of the worst man-made environmental disasters in U.S. history. Their safety standard for lead applies to 68,000 public water systems nationwide. Even with corrosion control, Edwards said the continued use of lead pipes throughout the country poses a constant public health risk. With Walters' assistance, Edwards and his team conducted the first major study showing that lead levels in the water of more than a hundred of the city's homes exceeded safe levels in 2014. Prior to that, the city purchased treated Lake Huron water from the Detroit Water and Sewerage Department. On average, lead provided 12.4 percent of chemical build-up on the pipes. Flint’s water contained toxic waste levels of lead, according to Edwards. The Flint water crisis did not begin on April 25th, 2014, when the city switched its water supply from Detroit’s system, tapping Lake Huron to its own on the Flint River. But as I continued to film with local residents, I was struck by how little the state seemed to be doing in response. “You can have hazardous waste levels of lead at the tap.”. I don’t expect anything I say will be taken seriously as I am no authority but I have followed the story from the beginning as I live in Saginaw, about 30 mi. or Was lead present in the Flint river, or did get into the water in another way? Hanna-Attisha became involved thanks partly to an August barbecue with two lifelong friends, one of whom happened to have worked for the Environmental Protection Agency in Washington when the city's taps spewed lead from 2001 through 2004. The National Guard hand out water testing jugs for residents at a fire station January 21, 2016 in Flint, Michigan. Keep up-to-date on: © 2020 Smithsonian Magazine. Doctors explain the long-term health effects of Flint water crisis Lead residues on Flint’s water pipes were much lower than those found on the lead service lines from 26 water utilities in the U.S. Half of the chemical build-up — 54 percent — on pipes around the nation was lead, more than four times as much as in Flint. Walters tried to contact city and state officials for guidance, but was mostly ignored. To Edwards, lead pipes and lead paint have a lot in common. The city's water supply had been contaminated by lead … The corrosive water pumping underneath Flint quickly ate away at the protective layer inside the city's old lead pipes, exposing bare lead to the water flowing through them. Omitting orthophosphate, which controls metal corrosion, caused lead embedded in the pipes to leach into the water. The 1982 Tylenol Terror Shattered American Consumer Innocence, Without These Whistleblowers, We May Never Have Known the Full Extent of the Flint Water Crisis, Three People Hit With Criminal Charges Over Flint Water Crisis, a new report, published yesterday in the journal, Freed of 1,000 Years of Grime, Anglo-Saxon Cross Emerges in Stunning Detail, Officials Seize 27,400 Artifacts Looted by a Single French Treasure Hunter, Ivory From 16th-Century Shipwreck Yields Clues to African Elephants' Decline, With Lightning Speed and Agility, Germany's Ar 234 Blitz Jet Bomber Was a Success That Ultimately Failed, Missing Great Pyramid Artifact Found in Cigar Box in Scotland, A Cider-Can 'Camera' Captured Eight Years in a Single Photograph, How Bullwinkle Taught Kids Sophisticated Political Satire, Hegra, an Ancient City in Saudi Arabia Untouched for Millennia, Makes Its Public Debut, $340,000 Surrealist Painting Found in Recycling Bin at German Airport, The Aztecs Constructed This Tower Out of Hundreds of Human Skulls, Why Just 'Adding Context' to Controversial Monuments May Not Change Minds, The Winter Solstice Begins a Season of Storytelling and Ceremony, What the Pandemic Christmas of 1918 Looked Like, How Pepper Plants Pick the Perfect Path for Putting Down Roots, The Inspiring Quest to Revive the Hawaiian Language, The New Science of Our Ancient Bond With Dogs, Why Seagrass Could Be the Ocean's Secret Weapon Against Climate Change. The researchers wanted to compare these amounts to pre-crisis levels. Lead levels in one home’s tap water ballooned to nearly 50 times more than the EPA’s action standard. Concern among Muslims over halal status of COVID-19 vaccine, Watch According to the Michigan Civil Rights Commission, “The Flint Water Crisis … Flint made the switch to getting its water from the Flint River back in April 2014, as a money-saving exercise. Meanwhile, other metals like aluminum and magnesium appeared to take the lead’s place. So instead, they compared Flint’s waterworks to pipes inspected across the U.S. in 2008, including a location near Flint, as well as pipes examined in London, Ontario in 2010. Give a Gift. Roni Dengler. Photo by Rebecca Cook/REUTERS. Edwards is now working to study the efficacy of Flint's citywide efforts to replace lead pipes, and says this study is just the first step in getting the full picture. Olson’s team only measured lead that dissolved in the water and acknowledged this limitation in their report, too. • What caused lead to get into the water? Bridge Magazine should consider an article highlighting Lansing's achievement in full replacement of lead lines and Flint's rejection of Lansing Board of Water and Light's innovative methods and the cost of that rejection in both financial terms and potential failure to get to 100% of all of Flint's lead service lines. 17th Annual Photo Contest Finalists Announced. People used to believe that lead paint was not hazardous so long as it wasn’t chipping or flaking. Orthophosphates create a mineral coating that keeps toxic lead stuck to pipes. Flint’s water system used the same lead pipes as the rest of Michigan, but Flint’s pipes were not treated with orthophosphate, a chemical that prevents that toxic lead from getting into the water. While Walters had plastic pipes inside of her house, many older homes have galvanized iron pipes in their walls, meaning that removing any chance of lead contamination would take costly renovations. Dr. Mona Hanna-Attisha testifies about lead contamination of the Flint, Mich., water supply during a U.S. House hearing in 2016. At this point, Flint's lead levels are better than some other Michigan cities.
