Widespread use of road salt over the last several decades has increased significantly the concentration of sodium and chloride in the environment.  Many lakes in the Adirondacks now exhibit chloride concentrations many times higher than background levels and AWI estimates that 72% of lakes participating in our Adirondack Lake Assessment Program are influenced by road salt.  Road salt can result in a variety of impacts to human and wildlife health, particularly in near road environments that receive direct runoff such as roadside streams or vernal pools.  These are improvised knitted and felted coasters illustrating the increasing amount of sodium and chloride measured in Lake George by the Jefferson Project and using historical information from their data dashboard.
