Dakota County has reduced its salt usage on county roads by 40 percent over the last eight years, according to County Commissioner Joe Atkins, who added that the county's 2018 budget allots 25 percent less for salt materials while maintaining its effectiveness.
County workers have improved methods of applying salt and employees are trained better, Atkins said. And Kevin Schlangen, Dakota County fleet manager, said that truck equipment changes, both mechanical and computer-controlled, and different chemical combinations helped reduce the use of salt.
"It's a great story that other agencies ask us about all the time," he said, in an e-mail.
Road salt ends up in Minnesota's lakes and rivers, and studies have shown that excessive use has a negative effect on ecosystems and threatens their ability to support native fish and plants.
The Minnesota Pollution Control Agency says that groundwater in the metro area also is affected, with enough salt showing up in nearly a third of monitored wells to hurt aquatic life and affect the taste of drinking water.

MnDOT awards $1.5 million for intersection
The Minnesota Department of Transportation has awarded $1.5 million to Carver County to help reconstruct the Hwy. 18 (Lyman Boulevard)-Hwy. 41 intersection in Chaska.
Plans for the $4.1 million project include a roundabout to allow vehicles, pedestrians and cyclists to safely pass through the intersection.
The intersection currently is controlled by a temporary traffic signal, which county officials said made it dangerous and overburdened. Traffic volumes are expected to grow there as nearby businesses expand.
