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!
Being in Wisconsin as well, I always wonder how the environment copes with crazy amount of salt that gets used on the roads during bad winters. We’ve had winters where they ran out of salt and started using sand.
Salting the roads is just another stupid thing we do to destroy everything around us
