Monitoring the Road Salt Reduction Pilot Program in the Lake George Drainage Basin
Dr. Jim Sutherland, Scientific Advisor the for The Fund for Lake George, and Chris Navitsky, Lake George Waterkeeper, will describe a road salt reduction monitoring program in the Lake George basin, coordination with New York State, and how to balance water quality and human safety in winter road maintenance. This issue has risen to prominence as the “new acid rain” since chloride concentration in Lake George were found to have increased about three-fold from 1980 to 2009, due primarily to winter road de-icing applications. During the same time period, tributaries and soils in basin watersheds with roads receiving winter road salt exhibited elevated chloride concentrations, sometimes in excess of Lake George itself.

In 2018, the FUND for Lake George and the New York State Department of Transportation agreed on a pilot program in which the State would reduce winter road salt application on 17 miles of state roads and the FUND would conduct environmental monitoring to evaluate the effects of the reduced application on tributaries that discharge to Lake George. In 2019, the monitoring began, and it is expected to continue until 2022.

Participants should expect approximately 30 minutes of presentation followed by a facilitated, 20-minute Q&A period.

This presentation describes work conducted as part of the Environmental monitoring program to evaluate the New York State Department of Transportation Road Salt Reduction Pilot Program in the Lake George drainage basin project, which is funded by Lake Champlain Sea Grant, the FUND for Lake George, and its partners.

This seminar is part of the Lake Champlain Sea Grant Seminar Series.
