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.

In 2016, researchers said lead was no longer detectable in many homes. The proposed settlement in the Flint water crisis where residents were harmed by lead-tainted water is now $641million - and the state plans to borrow $600million for the payout. That’s because Olson’s figure is likely an underestimation. 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. However, tests have shown Flint's tap water has improved greatly since the depths of the water crisis. Olson and her colleagues at the University of Michigan in Ann Arbor, just 50 miles south of Flint, wanted to help. Meanwhile, the lead service lines from Ontario mirrored those in Flint. The absence of orthophosphates made the lead vulnerable to dissolving off the pipes and into the water supply. However, tests have shown Flint's tap water has improved greatly since the depths of the water crisis. It accumulated even more toxins from the lead pipes. As Flint River water contacts lead, particularly in areas where water is stagnant, it leaches into the water supply inside homes and businesses. Those methods include adding phosphates to the water, which help keep lead from dissolving into the water flowing through the pipes. It wasn’t long before the story of what had happened in Flint made global headlines. https://www.pbs.org/newshour/science/study-confirms-lead-got-flints-water.

There are so many lies being told about the Flint water story. Today she says the water … 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. “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. Terms of Use 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. Why? "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.

The pipes are a reservoir of lead that can readily detach and pose a hazard to people, Edwards said. Obama drinking the water was mostly a stunt, if a well-intentioned one, as was Gov. Orthophosphates create a mineral coating that keeps toxic lead stuck to pipes. And the ridiculously corrosive water running from the Flint River turned out to be eroding both the iron and the lead in the water mains and service lines to Flint homes. 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. 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. All Rights Reserved. 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.

In Flint, Michigan, a scandal over lead-tainted water keeps getting darker. 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.
