Turning to beet juice and beer to address road salt danger

Looking to strike a balance between ice-free roads and clean waterways, public works departments around the country are working to cut their salt use in winter by slathering the roadways with beet juice, molasses, and even beer waste to make them safer. Rock salt for decades has provided the cheapest and most effective way to cut down on traffic accidents and pedestrian falls during winter storms. But researchers cite mounting evidence that those tons of sodium chloride crystals — more than 20 million nationwide each year — are increasing the salinity of hundreds of lakes, especially in the Northeast and Midwest. That is putting everything from fish and frogs to microscopic zooplankton at risk. Agencies from New Jersey to North Dakota are using a mixture that includes beet juice; New Hampshire and Maine use one with molasses. Highway departments also have turned to beer waste, pickle brine and, in at least one Wisconsin county, cheese brine.
