Spreading a few loads of salt across your driveway is an easy way to ward off your snow woes, and it’s certainly faster than putting in the work behind the shovel.
Ecosystem Impacts
The impacts of salt on wildlife have proven myriad. According to a review Relyea published with a coauthor in Freshwater Biology, the most affected organisms are those that form the base of aquatic ecosystems—zooplankton. These creatures eat algae and provide food for other invertebrates and small fish.
Rising Human Pressure
These are just a few examples, but water salinization doesn’t only affect wildlife. Salt that seeps into waterways can also get into drinking wells, affecting human health in the process.
How Do We Fix the Problem?
Alternatives like beet juice and different chemicals mixtures of salt are marketed as safer, more environmentally friendly alternatives to the sodium chloride typically used.
How does road salt affect trout?
Recently, he found that road salt can reduce the size of rainbow trout hatchlings by about 30 percent, influencing their ability to elude predators and decreasing the number of eggs they lay.
What did Snell-Rood's work show about salt?
Snell-Rood's work shows just how profound an effect salt can have on an ecosystem.
Why are moose so hard to see?
Because they’re so close to this high speed traffic, and going back and forth across the road to get to the salt pools, some of them get clocked ,” Rea says. He adds that the moose are often active at night, which makes them hard to see on roads where cars sometimes only pass every 10 minutes or so.
How does salt affect plants?
Those effects can also be less direct than accumulation in plant life: By attracting some species to roadsides, salt can put animals in danger from getting hit from passing cars. They could also then be exposed to chemicals from car exhaust, spilled gas or heavy metals from break pad run off and other things.
How does algae affect the economy?
It can also affect the economy via tourism and property values, Relyea says. Even non-toxic algae can make water cloudy or murky, which is bad aesthetically for cottagers and others. “Having more algae and less clarity in the water makes the value of those lakes go down to people,” he says. “It’s not just a biological problem. It’s an aesthetic problem, a tourism problem, an economic problem; it’s all of these things.”
Why do cities like Chicago and Minneapolis spread salt?
Cities like Chicago and Minneapolis spread the stuff liberally because it helps lower the freezing point of water, and cuts relatively quickly into ice on contact. It’s road salt, and it’s ubiquitous to anyone who grew up in a northern climate.

Why is road salt so controversial?
Yet the use of road salt is extremely controversial due to its environmental impact, which is why we’ll look at some road salt alternatives.
How does salty water affect wildlife?
It then passes through the water treatment plant and ends up back in our waterways. When the salinity of the water rises, the oxygen content drops, making it difficult for wildlife to thrive. A 2018 study showed that 37 percent of the US drainage area has seen a salinity increase over the past 50 years, citing road salt as the main cause, especially in colder northern states.
How does salt affect the soil?
Pollutes the soil and contaminates drinking water. Vehicles spray salt onto the side of the road when driving past. Once those snowbanks begin to melt, the salt permeates the soil in which we grow crops. It can also reach our groundwater supplies, which we rely on for drinking water.

A Washington State University study estimates that the US spends $5 billion per year on fixing salt-damaged infrastructure This includes fixing roads, bridges, buildings and maintaining their fleet of snow removal vehicles.
Where does road salt come from?
Road, or de-icing salt, comes from naturally mined sodium chloride, and is essentially just poor quality table salt. Using salt to melt ice and snow layers is what leads to the typical brownish slush on roads in winter. Most US rock salt mines are located close to Cleveland, Detroit, New York State, Louisiana, and Kansas.

Hurts our furry friends. Contact with the de-icing salt leads to inflammation of animal paws, especially dogs and cats. Additionally, according to Concordia University, elk and moose are often drawn onto roads to get their salt fix, resulting in accidents that are harmful for both them and humans.
When does Road Salt Not Work?
Road salt cannot be used on surfaces that are 15 degrees or lower. Being in the Midwest means temperatures often drop lower than 15 degrees during the winter months. During these brutally cold times, road salt does not have the effect that is needed on the ice. This is when people need to be more careful about going out and about. We recommend staying indoors during these times if possible.
Why Is Road Salt Used in The Winter?
Precipitation starts to freeze at 32 degrees Fahrenheit and road salt stops the water from freezing on the roads. However, for road salt to work properly, there must be some water on the road. A brine solution is often sprayed first to pre-treat the roads surface. The preprocess of the brine solution and putting down salt on the roads helps to reduce or eliminate the roads from freezing over and becoming icy. This allows for people traveling, including emergency vehicles, ambulances, police cars, and fire trucks to get where they need to go.
What Road Salt is Made Out Of?
Salt used on roads, sodium chloride, is basically the same as table salt. The main difference is the coarseness of the salt. Table salt is purified, grounded, and has iodine added to it whereas Rock salt is what is used for roads. Rock salt is mined underground from salt crystals. People that mine for the salt use dynamite to break apart the salt and then it is hauled away to crushing machines. Salt is mined all over the world and there are plenty of mines located all around the United States. It is a process that is continual and happens all year long so that there will be plenty of salt to be used in a variety of areas that have trouble snow and ice during the winter months. Rock salt is stored in the off months in places that are made specifically for this purpose. Storage areas must be kept completely dry so that the salt is not destroyed.
