Eighteen months later, in the fall of 2015, researchers discovered that the proportion of children with above-average lead levels in their blood had doubled.
The city reconnected to Detroit’s water system in October, but the damage was done. Water from the Flint River was found to be highly corrosive to the lead pipes still used in some parts of the city. Even though Flint River water no longer flows through the city’s pipes, it’s unclear how long those pipes will continue to leach unsafe levels of lead into the tap water supply. Experts currently say the water is safe for bathing, but not drinking.
A group of Virginia Tech researchers who sampled the water in 271 Flint homes last summer found some contained lead levels high enough to meet the EPA’s definition of “toxic waste.”
