Road and sidewalk salt -- too much of a good thing?
With the onset of colder weather, the Izaak Walton League and local conservation groups are launching a new year of the Salt Watch program in the Philadelphia region.
While road salt (sodium chloride) helps keep roads and sidewalks safe during icy weather, the salt eventually washes into watersheds where it damages streams and water quality.

The Izaak Walton League created Winter Salt Watch to give volunteers the tools to monitor levels of salt pollution in local waterways. The program aims to ensure transportation safety while protecting clean water through best practices.
