At least 33 US cities used water testing 'cheats' over lead concerns [View all]

At least 33 cities across 17 US states have used water testing “cheats” that potentially conceal dangerous levels of lead, a Guardian investigation launched in the wake of the toxic water crisis in Flint, Michigan, has found. Of these cities, 21 used the same water testing methods that prompted criminal charges against three government employees in Flint over their role in one of the worst public health disasters in US history.
The crisis that gripped Flint is an extreme case where a cost-cutting decision to divert the city’s water supply to a polluted river was compounded by a poor testing regime and delays by environmental officials to respond to the health emergency. The Guardian’s investigation demonstrates that similar testing regimes were in place in cities including Chicago, Boston, Philadelphia, Detroit and Milwaukee.
Marc Edwards, the scientist who first uncovered the crisis in Flint, described water testing in some of America’s largest cities as an “outrage." “They make lead in water low when collecting samples for EPA compliance, even as it poisons kids who drink the water,” Edwards, a Virginia Tech scientist, said. “Clearly, the cheating and lax enforcement are needlessly harming children all over the United States. “If they cannot be trusted to protect little kids from lead in drinking water, what on Earth can they be trusted with? Who amongst us is safe?”
Testing methods that can avoid detecting lead include asking testers to run faucets before the test period, known as “pre-flushing”; to remove faucet filters called “aerators”; and to slowly fill sample bottles. The EPA reiterated in February that these lead-reducing methods go against its guidelines, and the Flint charges show they may now be criminal acts. In the nine years since the EPA last updated lead regulations, a substantial body of peer-reviewed science has shown no level of lead is safe for humans. Tiny amounts are associated with impaired development and behavioral problems in children, and exposure is linked to a propensity to commit violent crimes.
