"A Guardian investigation reveals that testing regimes similar to that of Flint were in place in major cities including Chicago, Boston and Philadelphia".

"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 US’ worst public health disasters.

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."
