"Happy winter, Minnesota! We seem to love (hate?) our extreme weather here, and our public works crews make it possible even to bicycle through the nastiest of wintry conditions. But many Minnesotans don’t realize that road and sidewalk salt is polluting our waters. When snow and ice melt from roads, parking lots, and sidewalks, the salt we apply to those surfaces goes with it, washing into our lakes, streams, wetlands, and groundwater. It takes only one teaspoon of road salt to permanently pollute 5 gallons of water. Once in the water, there is no way to remove the chloride that comes from salt; at high concentrations, chloride can harm fish and plant life. In the heart of a cold Minnesota winter, come share a cup of coffee and pastry—and learn how road salt is impacting our water resources, what we can do about it, and how the MN Pollution Control Agency is addressing the issue."More: http://www.nps.gov/miss/naturescience/riverforum.htm
