Iowa. But road salt also comes with major drawbacks: Salt is corrosive. For the same reason, road salt threatens pipes that bear drinking water, scientists say. "It's like when people historic period, their bones lose calcium and go brittle and are more than likely to crevice," Shi said. It snows more in Georgia than South Carolina and it shows SC uses sand. A city worker threw salt from a truck in New York City last year. But where does it go afterward? Xianming Shi is an assistant director. Please also read our Privacy Notice and Terms of Use, which became effective December 20, 2019. Porous or permeable pavement allows standing water to seep through, removing water from roads that would normally go through freeze-thaw periods, thus preventing ice formation on the roads. By 2013, 26 states were sprinkling roughly 17 million tons of salt on their roads each winter. Mostly used in roadway deicing. "The Romans allegedly salted the globe to vanquish their enemies, and we at present do the aforementioned to ourselves at a once unthinkable scale," Edwards said. You need A LOT of a substance to cover freeways and roads in any given state, and a . Magnesium chloride (MgCl2)is considered to be safer than NaCl but requires twice the amount to cover the same area, making it more expensive. Facebook, Follow us on The amount of salt used for deicing roads and highways has increased over the years along with the year-round transportation of goods and services. The chemical is effective at keeping roads free of snow and ice, but it also has damaging consequences, according to a growing body of research. Oftentimes, extra chemicals will be mixed in. Relyea studies what that means for aquatic life. Now, Nissens organization, Stop Over Salting, is pushing for Minnesota to pass a bill to reduce that figure by helping applicators learn how to use less of it a technique called smart salting.. Now, with climate change encouraging excessive salting by making winter storms more unpredictable, officials in states like Minnesota are starting to realize the magnitude of the problem. The reason, she said, is because the states freshwater bodies are in a crisis: 54 lakes and streams are impaired by high salt concentrations, meaning they fail to meet federal water quality standards, while dozens of others are drawing closer to that tipping point, according to the Minnesota Pollution Control Agency. 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. Arkansas. These resources are freely available online at, New Hampshire Department of Environmental Services -. Road salt is basically sodium chloride much like table salt and, leftover after prehistoric oceans evaporated, with huge mines in Ohio, Michigan, New York, Kansas, and Louisiana. It can corrode the steel in cars, trucks, bridges, and reinforcing rods in concrete weakening valuable infrastructure. There's less mystery nearly the chemistry. Ingredients in ice melts can range from seriously toxic to non-toxic. The best solution is a widespread, decreased use of road salt. Since 2012, the State has been applying a brine solution (23.3% salt-water solution) to the roads before a forecasted snow event. In some areas, moose and elk get attracted to the salt and wander onto roads, increasing the risk of crashes. Wisconsin. Instead, its going to be crucial to encourage safer winter driving habits like asking people to stay home during storms whenever possible, or to drive more slowly even on a highway. Yes, CDOT uses salts on the roads. Donate today to keep our climate news free. Pennsylvania is second in total costs at $246.eight 1000000, while iv New England states round out the top five in costs per lane mile: Massachusetts ($7,233), Vermont ($4,967), New Hampshire ($four,815) and Maine ($4,148). to the salt and wander onto roads, increasing the risk of crashes. "Peradventure your state budget has been decreasing every single year," Fay said. Each twelvemonth, Americans spread more than 48 billion pounds of salt on roadways to ward off the effects of winter weather. Rock salt is very effective at melting snow and ice and is considered to be pretty cheap. Twitter, Follow us on "If you take those all into account, then salt is really expensive," he says. Ingestion of these minerals can cause a varying degree of symptoms and health issues. New Mexico. The Reason For All This Salt. In New England, road salting is a necessity to keep people safe during snow or cold weather as they drive to work or take their kids to school. Louisiana. Before World War II, few US cities used salt in the winter. Unfortunately, no one's yet figured out a perfect alternative to salt, which is still the cheapest and easiest way to unfreeze roads. While engineers have developed better alternatives, they have not been widely implemented in part because they require upfront costs for purchasing equipment, Ms. Kelly said. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); A nonprofit, independent media organization dedicated to telling stories of climate solutions and a just future. Brine: Salt-rich liquid, either extracted directly from salt lakes/salty groundwater, or by dissolving salt in water. During the winter, road salt is applied to the roadway to melt snow and ice. It's unlikely, for instance, that we'll get self-heating roads in remote mountain passes, where ice is really a problem. While sodium is less water soluble and lodges in soil, the vast majority of chloride washes away with the rain. 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. In our complex society, the public demands that governments keep traffic flowing smoothly and minimize the tragedy of car crashes. Ms. Kelly said the accumulation of salt in drinking water reservoirs in some places was harming people on low-sodium diets. Shi says these are still further off, though, and likely to be pricey. Municipal highway agencies were not surveyed in this study. But salt use has tripled since then. Its an issue that requires attention now, said Bill Hintz, an assistant professor in the environmental sciences department at the University of Toledo and the lead author of a recent research review published in the journal Frontiers in Ecology and the Environment. Along with using salt, the state also plows roads and provides a map on their website of snow routes. When animals venture into roadways for salt, they're also exposed to dangerous chemicals, such as car exhaust, spilled gas and metal shaving from brake pads. In December 2014, astudy by the US Geological Survey found that chloride levels were on the rise in 84 percent of urban streams studied with 29 percent exceeding federal safety limits of 230 milligrams per liter for at least part of the year. The big drawback for many of these solutions, Shi notes, is that they tend to cost more. New Jersey hasn't contributed data since 2014-15, but the 42 tons it used per mile that year would identify it near the top. Fay recommends a few simple steps to route crews to limit table salt use and its impacts: Cover salt piles to protect them from atmospheric precipitation and calibrate equipment to ensure proper common salt distribution. Alaska Connecticut Maryland Massachusetts Delaware New Hampshire New Jersey Ohio Pennsylvania Rhode Island Washington D.C. Illinois Indiana Iowa Missouri Maine New York Michigan Minnesota West Virginia Vermont Virginia Wisconsin The worst states for rust are primarily located in the Northeastern portion of the U.S. For regions that experience frequent snowstorms, salting can help keep streets and sidewalks clear and prevent slick driving conditions. 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). Salt supplies have been replenished in all 95 counties in preparation for the winter season, and crews have readied snow plows and brine trucks. The salt in those waterways also kills off fish, plants, and amphibians. Unfortunately, no one's yet figured out a perfect alternative to salt, which is still the cheapest and easiest way to unfreeze roads. For example, it says that Massachusetts, Connecticut and Maine likewise autumn in the top ten, while Pennsylvania ranks 13th, Maryland 16th and Delaware . Shi says these are still further off, though, and likely to be pricey. Another technology gaining traction is solar roads, made up of engineered solar panels that can be walked and driven upon. Alabama. 4) Beet and tomato juice de-icers. Chloride levels were on the rise in 84 percent of the urban streams USGS studied. North carolina. Chloride, in particular, binds tightly to water molecules, and can be highly toxic to organisms like fish, amphibians, and microscopic zooplankton, which form the basis of the food chain in a lake or river. Indiana. 1 2 3. But convincing them is a challenge, she said, because people have come to associate the sight of salt with winter safety. A report past AAA establish road table salt could exist costing car owners as much as $3 billion annually in repair costs. The environmental toll and long-term costs of rock salt have inspired some states to search for alternative management practices. 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). The others have written policies all with different levels of sophistication, particularly with respect to application rates and techniques. Rock salt: solid masses of salt crystals that form rocks made almost entirely of salt. (The salt works by lowering the freezing temperature of water, preventing ice from forming.) At worst? Still, little has been done to address the environmental impact of road salt because it is cheap and effective, said Victoria Kelly, the environmental programming manager at the Cary Institute. Highways depots, spreading vehicles and the de-icing agent all contribute, but with good management, this burden can be minimized.. We can still have our winter mobility and be safe with less salt., To support our nonprofit environmental journalism, please consider disabling your ad-blocker to allow ads on Grist. newsletter, Center for Environmentally Sustainable Transportation in Cold Climates. $5 billion to pay for the resulting damage caused by salt. Facebook, Follow us on allmountain40. One 2010study from the University of Waterloo found that a handful of "best practices" can reduce local chloride levels by half. And that's not even counting the cost of salting cities or rural roads. For instance, road salt is less effective at melting ice when temperatures. The brine is used all over the United States. New York, Massachusetts, Michigan, New Hampshire, and Vermont report the highest annual salt loadings. when it gets extremely cold, other chemicals like magnesium chloride or calcium chloride are mixed in. Salt will nestle in past the paint, attach itself top your cars exposed metal frame and eat that sucker dry. Possibly good: Virginia. All rights reserved. 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). (Wisconsinhas even been using cheese brine for this purpose.) A 2017 written report by her squad constitute that well-nigh one-half of the 284 freshwater lakes in their sample in the Northeast and Midwest had undergone "long-term salinization." At the top are five New England states that used the most salt per mile of road lanes over the past four years: The agency has since reduced using salt crystals, which are less effective because. Chloride, in particular, doesn't get filtered out naturally by soil and accumulates in waterways. Moose, elk, and other mammals visit natural salt licks to fill up on sodium. A 2018 study of wells in Dutchess County, N.Y., found that sodium concentration in wells reached levels as high as 860 milligrams per liter much higher than the federal and state recommendation that levels not exceed 20 milligrams per liter for people on very low-sodium diets and 270 milligrams per liter for people on moderately restricted sodium diets. The Minnesota bill, if it passes, would be one of the first state laws to encourage smart salting, a way to reduce road salt use while still maintaining winter safety.

"We're non putting everyone on Mars here," Siy said. It as well can stunt the growth of fish, similar rainbow trout, leaving them more vulnerable to predators. Although many tantalum-bearing minerals have been identified, the most For scientists, geoscientists and paleontologists in particular, access to public lands is crucial. The estimated average abundance of tantalum in Earth's crust is about 2 parts per million (or 0.0002%). https://www.nytimes.com/2022/01/07/climate/road-salt-water-supply.html. They use salt here in Tennessee, but since snow is not that much of an occurance, rust is not an issue here. 5) Pavement that doesn't freeze or corrode. (Baltimore Sun/Tribune News Service/Getty Images). 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. Perhaps the most unexpected effect comes with land animals. Elite Eight: March 30-31. Please click here to see any active alerts. Oklahoma. Depending on what models are being recalled, Canada can be included too because, well its Canada and it snows a lot there. 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). JavaScript appears to be disabled on this computer. Google Pay. Some counties, like Jefferson County, Wis., have already made changes. Even a small amount can be dangerous when ingested, causing vomiting, diarrhea, lethargy, disorientation, and even death (by sodium toxicosis) in high amounts. Cold-weather states that have to use a heavy dose of salt in the winter are sometimes referred to as the salt belt. Every now and again youll see a recall or investigation that is limited to this this specific region. Maine, New York, Vermont, Virginia, and Wisconsin have the most detailed policies. In extremely cold temperatures, sand can freeze in hazardous clumps. (Eddie Welker/Flickr). If officials have advance warning of a storm, they can spread salt on the roads beforehand. And for that, we can thank the 15 million tons of salt we dump on our roads and sidewalks each winter to melt away the snow and ice. An official website of the United States government. Secure .gov websites use HTTPS Baltimore County road crews were just spreading salt at this point of the morning, as the roads were warm enough for melting to keep up with the falling snow. The belt, however, sometimes grows or shrinks depending on the recall. But while pouring tons of salt on roads makes winter driving safer, it also has damaging environmental and health consequences, according to a growing body of research. Traditional geoscience departments commonly require 60 semester hours of geology and geology-related elective courses to achieve a BA/BS degree. Snowplows and a huge pile of salt are ready for the first snowfall on October 17, 2013, in Buffalo, New York. New Hampshire. Cars are especially susceptible to corrosion after being exposed to road salt for eight years or more, reports the National Highway Traffic Safety AdministrationGet more car care secrets in this post about how to keep a high-mileage car running. One 1992 study found that spreading salt can reduce car accidents by 87 percent during and after a snowstorm. Salt brines are increasingly used in some areas, but the vast majority is still rock salt. And people generally accepted that the roads weren't always passable in icy conditions. Cities like Milwaukee are tryingto ration what salt they have. Putting ice or any other chemical cold pack directly on the skin, whether manufactured or not, can cause frostbite in minutes. Some cities have opted for proactive solutions preventing snow and ice from building up in the first place, rather than melting it with salt once its already a problem. 2K views, 27 likes, 7 loves, 18 comments, 0 shares, Facebook Watch Videos from Dbstvstlucia: DBS MORNING SHOW & OBITUARIES 25TH APRIL 2023 APRIL 2023 No. "Approximately 15 million tons of deicing salt are used each year in the United States," said Rena Silverman, a journalist for National Geographic. While table salt helps go along roads clear in winter, information technology doesn't but disappear with the snow. The town spent over $1 million to install the first 250,000 square feet of underground tubing, and the system still only encompasses a few streets in Hollands main downtown shopping area, although Sasamoto said it could expand along with future development. It's unlikely, for instance, that we'll get self-heating roads in remote mountain passes, where ice is really a problem. 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. He estimates the US now spends $2.3 billion each year to remove snow and ice from highways. America's habit to road salt the "acid pelting of our time" tin be cured, said Eric Siy, the executive director of The Fund for Lake George, a nonprofit supporting scientific efforts at the lake in upstate New York. Snowy roads are driving a nightmare salt habit. Shi studies how connected infrastructure, such as cars tapped into an information-sharing network, can increase winter road safety. One study in Utah estimated that salt corrosion now costs the US $16 to $19 billion per year. One 1992, found that spreading salt can reduce car accidents by 87 percent during and after a snowstorm. One in x of them reached a threshold where scientists worry nigh impacts on aquatic life. Engineers like Shi. The Salt Belt is the U.S. region in which road salt is used in winter to control snow and ice. Its vital reporting made entirely possible by loyal readers like you. In some areas, salt prices have risen as much as 30 percent. ClearRoads information shows winter maintenance is expensive. Blue Top 3 producing states: LA (32%), NY (27%), OH (24%). Arizona. Reader support helps sustain our work. But it's an even bigger deal for all the other freshwater organisms in those lakes and streams. 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. Thats changed in recent years. Follow us on Road salt alternatives? Even with the recent shortage, salt is extraordinarily cheap, and cities have a limited budget for de-icing their roads. 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. The EPA says this can reduce salt use41 to 75 percent and is best done two hours before the storm. Interstate 5 is the busiest roadway on the west coast and is vital for moving people and goods to support the economy. 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. Sometimes youll even receive an anti-corrosion warranty with a new car that lasts a couple years. Kansas. cars, trucks, concrete, and steel bridges. Just as alarming, when that salt dissolves and splits into sodium and chloride,it washes away into rivers and streams. "It was merely and so obvious that when a lake was virtually whatever kind of urban environment, the chloride concentrations tended to be going upward," Dugan said. Still, these only reduce the need for salt somewhat; they don't solve the problem entirely. The Oregon Department of Transportation in 2012 launched a pilot program, salting two stretches of road near the states border to avoid the sudden change in conditions. Transportation departments can add chemicals to the salt to inhibit corrosion or add coating to steel, but this gets pricey. The first natural-gas banin the USjust got shotdown, Bidens new vehicle emissions rules could speed the EV revolution, What a pending Supreme Court ruling could mean for Bidens new clean water protections, Amid fracking boom, Pennsylvania faces toxic wastewater reckoning. It may not be big enough. 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. Extra salinity can also affect oxygen levels and createdead zones in lakes. And the salty soil near roadways can kill trees and other plants. 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. 4.1K views, 50 likes, 28 loves, 154 comments, 48 shares, Facebook Watch Videos from 7th District AME Church: Thursday Morning Opening Session While there is not a perfect solution to the issue, there are alternatives that can significantly reduce salt usage without compromising driver safety. "At that place'southward much less out in that location on what (table salt) does to ecosystems," Relyea said. Snow came early this year, and with it snow/ice road maintenance. Solar and wind companies are coming to rural Texas. Information technology's a problem that'south growing exponentially. Merely it comes at a cost: De-icing salt degrades roads and bridges, contaminates drinking water and harms the surround, according to a slate of scientists expressing growing alarm. Since 1988, the town of Holland, Michigan, has invested in a snowmelt system, which uses pre-heated water from a nearby power plant to warm sidewalks and roads through a network of pipes underneath the surface, eliminating the need for salting. Im not really sure. The US economy doesn't just grind to a halt every time there's a major blizzard. Quantity taxes can be based on either overall product weight or the amount of THC sold.

Top rock salt producing (yellow) and consuming (blue) states in 2014. Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius), and that includes ice on roadways. But road salt also comes with major drawbacks: Salt is corrosive, chewing through cars, trucks, concrete, and steel bridges. Maybe they just ride around on polar bears all winter. Once salt has entered the environment, there is no effective way to remove it. In 2015, he consulted with public works officials in Brick, New Jersey, and establish that road salt contributed to corrosion and high pb levels in the township's drinking water. . The issues encountered in Brick could occur in any of the thousands of public water systems across the country where road salt is used, Edwards said, adding that local water departments often don't empathise the risks of high chloride levels. Some say that salts corrosive properties slow down once the salt dries into a crusty white dust all over your car. You are free to share or distribute this material for non-commercial purposes as long as it retains this licensing information, and attribution is given to the American Geosciences Institute. The consequences of insufficiently salting roads. Brining involves laying down a liquid mixture of salt before a storm, which prevents ice from sticking and reduces the need for repetitive salting. 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). What is MDSS? Another alternative is the use a 50/50 salt and sand mixture. DOT, which uses about 150,000 tons of salt annually, says it applies less salt per mile than do other New England states. But rock salt's low cost does not include the potential damage to property, infrastructure, or the environment.
