GREEN BAY, Wis. (WFRV) – As winter weather continues to impact travel conditions across the state, communities are once again turning to road salt to keep communities safe.
Sustainably Speaking: Wisconsin flash freezes and the impact on aquatic life
During Winter Salt Week, environmental leaders take the spotlight in an annual effort to raise awareness about the environmental impacts of road salt usage.
Road salt, primarily made of sodium chloride, is an effective resource for melting ice – but once it’s applied, it doesn’t disappear.
Melted ice water carries the excess salt into storm drains, streams, groundwater and over time, chloride levels can continue to build, which can harm freshwater systems, fish, aquatic insects and plant life.
According to environmental experts, Wisconsin’s lakes and rivers are especially vulnerable because salt accumulations continue year after year. Unlike some other pollutants, chloride does not easily break down or evaporate.
Winter salt week also emphasizes that utilizing more salt does not lead to safer roads. Over-application can actually reduce traction, damage roads, vehicles and corrode infrastructure, leading to higher costs for taxpayers.
Studies show that applying the right amount at the right time is more effective than excessive salting after snow and ice have already made their fall.
Residents can play their role as well. Experts recommend shoveling early, using salt sparingly, and switching to sand or alternatives when temperatures drop to extreme cold.
