TIL that salt rock, the stuff used during winter, helped contribute to the Flint Water Crisis

Road salt on the city’s bridges raised the river’s chlorine levels, making the water more corrosive. This has continued into the present and may have been one reason poorly-treated Flint River water was so damaging to metal pipes.

I shared this because my city doesn't use rock salt during winter, and its pretty inconvenient as a driver. So I was surprised to learn why.

It's disingenuous to say it's the PRIMARY contributor, but it is a factor!
