Winter Roads Make Salty Streams teacher's guide
Salt used on winter roads could eventually make water supplies toxic to wildlife and unfit to drink.
"This Science Bulletin, Winter Roads Make Salty Streams that we are about to watch is based on the scientific research of Sujay Kaushal. He was interested in understanding if the salt we put on roads to melt snow and ice ends up in streams. We will be exploring the work reported in this Bulletin over the next week or so."
