The salt pollution challenge can be daunting: years and years of salt use have already penetrated surface and groundwater and will stick around for years to come. And salt is still the No. 1 way of keeping winter roads safe.
But the small highway crew in Hague, on the western shores of Lake George has started to show that if you use less salt on the roads, less salt will show up in the water. After the Hague crew reduced its salt use by nearly 70% over the last five years, researchers with RPI’s Darrin Fresh Water Institute have found an average 4% annual reduction in chloride concentrations in Hague Brook. More study is needed but it’s a positive sign that Hague is reducing salt on the roads and in the waters.
Read more about what Hague has been up to and my recent visit to their garage. I also spoke with North Country Public Radio Adirondacks reporter Emily Russell this week about the latest on the state’s road salt reduction task force.
The road salt issue has also started to draw more national coverage in recent weeks after a scientific research review published in Frontiers in Ecology and the Environment highlighted the dire public health and environmental downsides of rampant salt use – which has tripled in the last 45 years.
