Fluoride spill at water facility literally burns holes in parking lot cement

Interesting that the Fluoride compound that is added to American water supplies (and probably water supplies of other countries as well) is so corrosive it can burn holes in concrete and require the Hazmat team to come in to clean up the spill. Even though it is diluted when it is added to the water supply, I can't imagine that it could be good for you given how corrosive it is.
