Salt is a complex pollutant and a significant threat to freshwater ecosystems.  Among the issues NOT covered here are salt’s threat to the drinking water of millions. It can contaminate reservoirs and groundwater sources, and can alter chemistry to release toxins like lead. Salt brings up  environmental justice issues, urban design issues, even issues with home appliances and plumbing via water softeners.

Salt may also be addressed regionally and even locally. A simple search will uncover a lot of stories in the media and give you an idea of how your area is affected. The list of resources below is regional in scope. Got a resource you think should be here? Use the form below.
