I find it interesting that with all of the worries about pollution these days, every time it snows we put tons and tons of pollution on the roads to melt ice. I am talking about NaCl, in other words salt. I just read an article that talked about how much salt that we were put on the roads which each snow storm that we get, and where it runs to when it gets melted. Being a former "snow fighter" as we liked to call ourselves, limiting the amount salt was never an issue that we were concerned with, all we worried about was removing ice from roads. I found it very interesting that only a cup of salt into a 5 gallon bucket could kill fish, I understand that there is way more water that runs through streams and rivers, but there is still a lot that runs into them. I didn't know of too many studies that has been done to see what effects this has on the habitat and ecosystems in these areas.
