Is it just me, or does anyone else think that roads get salted very heavily during winter storms these days? Coming down the freeway on the way home from work, the car sounded like it was on a gravel road. Maybe I was only a half-mile or so behind the salt truck, so the road was freshly salted for me. But I’ve been seeing lots of salt residue on roads after storms, though, long after the roads have dried. Not to mention parking lots—those are getting highly salted too. Even sidewalks in public areas seem to be getting heavier ice melter treatments than in past years. They’ve been really enthusiastic over the NaCl and CaCl deposits at work this year. I just don’t remember salt being that heavily used in years past.
All that stuff has to go somewhere, y’know? It’ll end up in drains and back out into the lakes, or into the soil nearby the pavement. How much salt is really needed?
Maybe it’s only in metro Detroit, I don’t know. Detroit sits on top of salt mines; maybe the road commissions are getting a really good price on what’s left down there.
