Every winter, I wonder about the impacts of salting the roads on urban streams. We don’t do it much around here, but it sure feels like a lot of salt. A recent paper looked a some of those impacts in the Northeast and Southeast United States. While there were certainly some impacts farther north, the researchers didn’t find problems in the sites in the South Atlantic. Yet another reason to be thankful for the mild winters here!
