2025 Salt Symposium
The 26th Salt Symposium will be held Tuesday, August 5th, 2025. It is a day-long virtual event bringing together professionals around the world to share their expertise on current research, planning, and initiatives surrounding chloride: including snow and ice management, low salt design, water softening, wastewater, agriculture.
The Salt Symposium is an annual event focused on understanding the concerns, research, solutions, and management of chloride use and innovation that can move us to a lower salt future to improve community sustainability and protect vital freshwater systems and infrastructure.

12:40 PM – Winter Design for Pedestrian Safety & Chloride Reduction
David Veneziano
Iowa State University
David Veneziano is Safety Circuit Rider with the Iowa Local Technical Assistance Program (LTAP) at the Institute for Transportation at Iowa State University. He has over 18 years of experience in various aspects of transportation research, including winter maintenance safety, operations and equipment, roadway safety and operations, and Intelligent Transportation Systems. In addition, his experience includes outreach and training activities for safety treatments, roadside safety, work zone flagging and safety, and roadway signing and marking.
Carl Rosen is a Professor and Extension Soil Scientist in the Department of Soil, Water, & Climate at the University of Minnesota. He received BS and MS degrees in Horticultural Science from Pennsylvania State University and a Ph.D. degree in Soil Science from the University of California, Davis. His research and extension programs in Minnesota have focused on water quality issues related to fertilizer use and use of municipal and industrial by-products as amendments for agricultural soils. He has authored or coauthored numerous publications and extension bulletins about nutrient management, soil fertility, soil health, plant nutrition, and beneficial use of by-products for crop production.
1:40 PM | Afternoon Break
2:00 PM – Municipal Decision Making Around Winter Maintenance in Response to Climate
Wyatt Weatherson
Toronto Metropolitan University, Ontario
Wyatt is a second-year PhD student in the Environmental Applied Science and Management program at Toronto Metropolitan University. A hydrologist by training, part of Wyatt’s doctoral work seeks to combine quantitative and qualitative methods to better understand the perceived and actual drivers of winter deicer use across Ontario. Using key informant interviews, Wyatt seeks to deepen our collective understanding of management and decision-making processes in the winter maintenance industry to identify gaps in knowledge, and inform subsequent quantitative analyses of historical climate trends. The ultimate goal of this work is to understand how changing spatial and temporal temperature and precipitation patterns will influence the extent of deicer use in Canada.
2:30 PM – 5 MINUTE UPDATE: Cold Climate Center of Excellence Update
Andy Erickson
St. Anthony Falls Laboratory, MN
Dr. Andy Erickson is a researcher and engineer at the University of Minnesota’s St. Anthony Falls Laboratory. He studies water quality in urban watersheds, develops stormwater assessment and maintenance best practices, and designs innovative stormwater treatment technologies. Andy is co-director of the Cold Climate Center of Excellence for Stormwater Infrastructure Technologies, the Chair of the ASTM International E64 Committee on Stormwater Control Measures, and the Chair for the University of Minnesota’s Water Council.
