Warnings about the effects of road salt on freshwater bodies and ecosystems first started in the 1970s, said Bill Hintz, the studys lead author and an environmental scientist at the University of Toledo in Ohio. Ingestion of these minerals can cause a varying degree of symptoms and health issues. The Ike Dike is the Army Corps of Engineers largest project ever. That should trouble recreational fishers everywhere, he said, but salt contamination has also made it into drinking water, particularly in areas where people rely on deep wells to reach groundwater. Instead, it works by preventing snow and ice particles on concrete surfaces from attaching. De-icing allows traffic to keep moving, a benefit worth. An official website of the United States government. The freezing point of the water is lowered once the salt is added, so it the salt makes it more difficult for . This overreliance on road salt has severe environmental consequences. You need A LOT of a substance to cover freeways and roads in any given state, and a . 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. And so, they can consider new approaches similar the ones in Lake George. And people generally accepted that the roads weren't always passable in icy conditions. About 15 percent of people in the United States get their water from private ground wells, while the rest rely on community water systems, according to the Centers for Disease Control and Prevention.

Maybe they just ride around on polar bears all winter. We accept credit card, Apple Pay, and In addition, road salt can also infiltrate nearby surface and ground waters and can contaminate drinking water reservoirs and wells. While no perfect solution exists to keep our roads clear in winter, the number of tools available to public works departments continues to increase, allowing for a tailored approach to clear roads in an environmentally conscious manner without risking driver safety. JavaScript appears to be disabled on this computer. Shi says these are still further off, though, and likely to be pricey. In Britain, the Salt Association said that salt was the cheapest form of de-icing material and that it had a low environmental impact when used responsibly. De-icing allows traffic to keep moving, a benefit worth many billions of dollars. "Approximately 15 million tons of deicing salt are used each year in the United States," said Rena Silverman, a journalist for National Geographic. In 2009, the USGS said thatabout 2 percent of US drinking water wells it studied had chloride levels higher than the EPA's recommended threshold. If officials have advance warning of a storm, they can spread salt on the roads beforehand. The environmental toll and long-term costs of rock salt have inspired some states to search for alternative management practices. Top: California. Privacy Policy. Dr. Hintz said his review showed that elevated salinity levels in freshwater ecosystems had already caused a reduction in the abundance and growth of freshwater organisms and a reduction in their reproduction outputs. As Nina Rastogireported for Slate in 2010, high chloride levels interfere with amphibians' ability to regulatehow fluids pass through their permeable skins. when it gets extremely cold, other chemicals like magnesium chloride or calcium chloride are mixed in. More than 20 million metric tons of salt are poured on U.S. roads each winter, according to an estimate by the Cary Institute of Ecosystem Studies in New York, and the environmental costs are growing. Google Pay. Chloride levels were on the rise in 84 percent of the urban streams USGS studied. Magnesium chloride (MgCl2)is considered to be safer than NaCl but requires twice the amount to cover the same area, making it more expensive. While there is not a perfect solution to the issue, there are alternatives that can significantly reduce salt usage without compromising driver safety. [3], Road salt is a common cause for corrosion of automobile parts, and cars in the salt belt often experience more rapid rusting compared to other regions of the country, rendering them unsafe as brake lines, electrical wiring, and structural components are adversely affected. Of all salt consumed in the United States, about 43 percent is used for highway de-icing, according to the U.S. Geological Survey in 2020. CDOT moved to using mainly liquid de-icers, a.k.a., mag choride and the like, instead of old-fashioned sand and salt. He estimates the US now spends $2.3 billion each year to remove snow and ice from highways. In New York, the Adirondack Road Salt Reduction Task Force launched a three-year pilot program this month to reduce freshwater salt contamination. New Hampshire passed a similar law in 2013, while Wisconsin also has a salt wise training program. But aside from corroding metal and concrete leading to an estimated $5 billion worth of damages each year it also ends up in rivers and lakes, where it has toxic effects on aquatic life. Known as one of the greenest commercial buildings in the world, since it opened its doors on Earth Day in 2013 the Bullitt Center has been setting a new standard for sustainable design. It's unlikely, for instance, that we'll get self-heating roads in remote mountain passes, where ice is really a problem. The big drawback for many of these solutions, Shi notes, is that they tend to cost more. All donations doubled for a limited time. The states in this belt are, as youd expect, found in New England, the Mid-Atlantic and the upper Midwest. There are solutions, Nissen told Grist. Possibly good: Virginia.

See also Does Wisconsin Have A Port? The sand doesn't help to melt the snow or ice but increases traction, reducing the amount of road salt required. It also includes applicators learning how to calibrate their equipment to know how much salt theyre using in the first place, as well as when to stop salting (below 15 degrees Fahrenheit, for example, salt is much less effective).

Still, these only reduce the need for salt somewhat; they don't solve the problem entirely. But as America's highways expanded and became ever more crucial to the economy, that changed. Four states store all of their salt supplies in sheds, and these states, along with three others, are attempting to place all supplies of . There are huge upsides to salting the streets. DOT also says it does not use magnesium chloride when the temperature is above 25 degrees Fahrenheit because salt alone is effective at those temperatures. The EPA says this can reduce salt use41 to 75 percent and is best done two hours before the storm. Ingredients in ice melts can range from seriously toxic to non-toxic. From the onset of an event, our goal is to keep at least a single lane open in each direction and work towards bare and wet pavement across all lanes. Salt, after all, has plenty of drawbacks.

By lowering the freezing temperature of water, salt prevents snow from turning to ice and melts ice that is already there. These solutions may not be scalable to something like a four-lane highway, said Xianming Shi, an engineer and the director of the National Center for Transportation Infrastructure Durability & Life-Extension at Washington State University.

Once it enters a body of water, salt is almost impossible to remove, requiring expensive and energy-intensive processes like reverse osmosis. Geologic Occurrence They dont realize that this has a hidden consequence.. Officials said the storm began with rain, which washed away road salt and made it difficult to keep roads clear. The concept of smart salting encompasses a range of technologies and techniques. It has killed or endangered wildlife in freshwater ecosystems, with high chloride levels toxic to fish, bugs and amphibians, according to the Environmental Protection Agency. Making matters worse, Dugan's squad establish that chloride levels in lakes rose when merely 1% of adjacent state was developed.

Another alternative is the use a 50/50 salt and sand mixture. But it's an even bigger deal for all the other freshwater organisms in those lakes and streams. If the zooplankton die off, Hintz said, it can trigger a chain reaction that allows algae to flourish, causing toxic blooms and affecting native fish species that cant survive in murky waters.

Its vital reporting made entirely possible by loyal readers like you. Highways depots, spreading vehicles and the de-icing agent all contribute, but with good management, this burden can be minimized..

New Hampshire's state government became the first to use salt on the roads in 1941'42, and the practice spread as the interstate highway system grew.
