New Hampshire has been successful in reducing road salt use through improved management practices and policy. The portion that remains on roadways eats away at pavement and bridges. When snow fell, local governments would plow the roads and then spread sand and cinders around to improve traction. "We've become salt-addicted over the last 50 years, and we're now discovering that there are all these hidden costs," says Xianming Shi, an associate professor in civil and environmental engineering at Washington State University. Though seemingly harmless to us, rock salt can have corrosive effects in large quantities that affects cars, trucks, bridges, and roads resulting in approximately $5 billion dollars in annual repairs in the U.S. alone.

ROAD SALT IN WINTER. By lowering the freezing temperature of water, salt prevents snow from turning to ice and melts ice that is already there. "If you take those all into account, then salt is really expensive," he says. It broke 1 million tons in 1954, 10 million in 1985, and now averages more than 24 million tons a year . Another technology gaining traction is solar roads, made up of engineered solar panels that can be walked and driven upon. Along with using salt, the state also plows roads and provides a map on their website of snow routes. In 2013 the State launched, the "New Hampshire Road Salt Reduction Initiative" to address the high number of waters impaired by chloride (19 water bodies in 2008, and 43 in 2012). 1999-2023 Grist Magazine, Inc.

Of the 60 hours, typically half are required courses in geology. "Peradventure your state budget has been decreasing every single year," Fay said. Shi has worked on research for newer "smart" snowplows that not only measure pavement temperature but also detect residual salt that's already been laid down, as well as the presence of ice on the road. Privacy Policy. See also Does Wisconsin Have A Port? newsletter, Center for Environmentally Sustainable Transportation in Cold Climates. Ohio.

"And then we see, my goodness, information technology is everywhere, and it is a growing trouble.". But environmental activists and scientists argue that its possible to maintain winter safety while reducing the amount of salt spread on streets and highways. To put it another way, while consumption varies each year, the US now puts approximately10 times as much salt on its roads as it does in processed food: Road salt is basically sodium chloride much like table salt and comes from deposits leftover after prehistoric oceans evaporated, with huge mines in Ohio, Michigan, New York, Kansas, and Louisiana. Unfortunately, no one's yet figured out a perfect alternative to salt, which is still the cheapest and easiest way to unfreeze roads. Secure .gov websites use HTTPS But road salt also comes with major drawbacks: Salt is corrosive, chewing through cars, trucks, concrete, and steel bridges. Highway Salt nvironmental protection, properly, is a high public priority. Salt thats already been deposited might take years to show up in groundwater, and how much can be safely added without permanently damaging an ecosystem is an open question, he said. At the top are five New England states that used the most salt per mile of road lanes over the past iv years: Rhode Isle (44.2 tons), Massachusetts (34.vi tons), New York (28.0 tons), New Hampshire (25.1 tons) and Vermont (23.3 tons).

If sex-changing frogs don't business organisation you, this might: A Washington Country Academy professor estimates the country spends $5 billion a twelvemonth on infrastructure damages caused past road common salt and information technology might not most be enough. Due to its chemical properties, route common salt can exacerbate the damage roads already suffer each winter when they repeatedly freeze and thaw. But as America's highways expanded and became ever more crucial to the economy, that changed. Road crews use salt on roads and other surfaces in the winter Salt lowers the freezing point of water, which prevents ice from forming Salt loses its effectiveness once the temperature falls below 15 degrees In addition to clearing snow and ice from roads, plows also put down a lot of salt on roads and other surfaces this time of year. At the top are five New England states that used the most salt per mile of road lanes over the past four years: Rhode Island (44.2 tons), Massachusetts (34.6 tons), New York (28.0 tons), New Hampshire (25.1 tons) and Vermont (23.3 tons). There are exotic remedies like adding beet juice to the de-icing mix, which can help the salt stick in place and lessen the amount needed. One 1992 study found that spreading salt can reduce car accidents by 87 percent during and after a snowstorm. As snow and ice melt on roads, the salt washes into soil, lakes and streams, in some cases contaminating drinking water reservoirs and wells. Even a small amount can be dangerous when ingested, causing vomiting, diarrhea, lethargy, disorientation, and even death (by sodium toxicosis) in high amounts.
