Wilton Leads Saratoga Lake Region in Road Salt Reduction Efforts

WILTON — In a watershed where road salt runoff is steadily degrading water quality, the Town of Wilton has emerged as a model for innovation and environmental responsibility. 

Under the leadership of Highway Superintendent Mike Monroe, the Wilton Highway Department has implemented a series of first-in-the-region measures to reduce salt use — a move applauded by the Saratoga Lake Association (SLA) and environmental advocates.

Earlier this year, Wilton completed the calibration of all 14 of its large dump trucks used for winter salt spreading, with technical assistance from WIT Advisors. Each truck now has a precise chart in its cab showing the number of pounds of salt applied per lane-mile, tailored to that truck’s unique hydraulic setup. Monroe said this will allow operators to apply exactly the right amount of salt for each storm, improving efficiency and reducing environmental impact.

Wilton also equipped four trucks with “live edge” plow blades, which better conform to the road surface and allow operators to turn down the auger control on final cleanup passes. Monroe plans to install these blades on all large trucks in 2026.

In another major step, Wilton fabricated and installed a 2,600-gallon brine tank and dispenser on a straight truck. This will enable the town to pretreat main roads with brine — a strategy shown to reduce overall salt usage — during the 2025–26 winter season.

Monroe’s work comes as the Skidmore College Environmental Studies and Sciences Capstone Report, funded by the SLA, warns that chloride levels in Saratoga Lake and its tributaries are at or near toxic thresholds for aquatic life. The study found that road salt runoff from municipal and state highways is a major contributor, with chloride concentrations in some tributaries exceeding 10,000 parts per million during winter peaks.

SLA President, Dr.Jim DeMasi, praised Monroe’s leadership, saying, “Mike Monroe has set the gold standard for municipal highway operations in the Saratoga Lake watershed. He’s proving that safety and environmental stewardship can go hand in hand. We hope every municipality in the watershed takes notice and follows Wilton’s lead.”

For Monroe, the effort is about more than technology. “Calibration, training, and brining are just tools in the toolbox,” he said. “The real goal is to keep our roads safe while protecting the lake and our drinking water. We can do both — and do it better than before.”

With winter approaching, all eyes in the region will be on Wilton’s roads — and on the results of Monroe’s forward-thinking approach.
