19-2 Quantifying Nutrient Pollution Reductions Achieved by Erosion Remediation Projects on Vermont's Roads

Project Dates: Jul 1, 2019 - Jun 30, 2021
Project Description:

Transportation networks have been recognized as contributors to water quality impairment by discharging stormwater, sediment, and nutrients to receiving waters. These contributions can occur through chronic inputs of water and pollutant washed from the road surface during storm events or through episodic and often catastrophic road failure by slope failure during extreme storms. Watershed planning efforts in the state call for attention to this issue, and the recently-released Phosphorous Total Maximum Daily Load (TMDL) for Vermont Segments of Lake Champlain calls for reductions in phosphorus contributions from the transportation sector. This project will assess road drainage-related erosion and the effectiveness of mitigation measures.
