Here is the link to a website that gave great background information about the introduction of the use of salt to clear snow and ice from roadways. It gave us the year of origin, and a map of how use has increased over the past half century. It also gives the scientific reason that salt is able to melt away snow and ice. It is explained that salt lowers the freezing temperature of water to -21 degrees fahrenheit. This is a very interesting fact. The website will help us to introduce the project by giving the science behind it and a brief description of how much road salt is used nationally. From here we hope to narrow it down to a state and city-wide scope, and that way we will be able to guess at how much salt can potentially reach our local ravines. http://onlinepubs.trb.org/

Effects of Road Salt on Ecosystem By: Lucas and Jeffy
Our project is going to focus on how road salt effects the fish and overall ecosystem of the ravine.
