Here in the southern part of the northeast, NJ,NY,CT,MA, PA.....we now have have liquid deicer which the DPW guys tell me is the frack fluid from the gas and oil industry/ The stuff that's too toxic to leave in the ground. It used to get shipped to TX to put in old salt mines, they said. Now it gets spread around on the roads!!!! Cast iron manhole covers are turning orange and flaking away to dust, it's bad stuff. And they no longer wait for snow to fall, they pretreat the roads the day before so we can splash thru the stuff before it mixes with snow or water.
A friend who does car repair says 33% of his business is line replacement.
