Road Salt Threatens to Salinize North American

As springtime thaws the country, many are
sighing with relief as frost rescinds and flowers begin to bloom.
However, as the snow and ice melt away, few
realize the lasting impact the winter season will have on the future of
neighboring fresh bodies of water.
Salt, a universal melting solution for
roads and walkways around the country, is slowly making freshwater in North
America saltier.
This change in composition could lead to
serious consequences, which could go as far as to threaten sources of human
drinking water.
Since the 1940s, road salt, not too
different from regular table salt, has been sprinkled on roads as a way to melt
ice and protect drivers.
In fact, each year it is estimated that a
stunning 23 million metric tons of salt are used throughout North America for
this purpose alone.
This safety precaution may be well
intended, but the mass salting of our roadways is consequently contaminating
fresh water and posing threats to local ecosystems.
The
Great Lakes
The Twin Cities in Minnesota, known for its
chill and 10,000 lakes, served as a hotspot for scientists in a recent mass
study of several hundred lakes.
The two cities straddle the Mississippi
River, which since 1985 has shown an 85 percent increase in salt concentration.
This increase could only be caused by road
salt runoff, experts say, because the salt essentially has nowhere else to go.
This point was driven home further when
results showed that lakes within 500 meters of roads had higher salt levels
than those further from roadways.
While the Mississippi River has the
advantage of a flowing stream, which replenishes itself naturally, stagnant
lakes and ponds are not so lucky.
Their water replenishes less frequently,
making them the most vulnerable to pollution.
Experts go so far as to warn that failure
to decrease salt use could result in lakes becoming too salty to support
natural life by the year 2050.
These warnings strike eerily in unison with
recent calls for fresh water preservation due to the sheer lack of it.
Separate researchers have found that most
lakes are shallower than initially estimated in past limited studies, which in
short means “less fresh water” than anyone has ever expected.
With 18 percent of the world’s fresh water
found in the five Great Lakes, the salinization that was seen in and around
these communities could have dire consequences.
Just three years ago in 2014, Lake Erie
faced overwhelming algae and nutrient pollution that left 400,000 citizens in
both the United States and Canadian sides of the lake without drinkable water.
Similar issues have been unfolding
throughout the country, most famously in Flint, Michigan, where salty water
played a part in degrading the city’s water pipe system.
Experts urge that people reflect on the
direct impact humans have on freshwater ecosystems, not just through runoff,
but agriculture, the disposal of waste, and land development.
Salinization is one of the many threats
facing freshwater and even these startling numbers, according to researchers,
are “likely an underestimation” due to a lack of long-term data from Canadian
regions that also use heavy amounts of road salt.
Though local governments have cut back on
salt usage, most did so because of rising costs, not because of the threat its
use poses on waterways and the ecosystem.
It is necessary that governments not only recognize this threat but take steps to protecting and promoting the recovery of freshwater ecosystems.
The population is responsible as well to
use alternative, eco-friendly ice melting options existing in most households,
such as coffee grounds, sand, or beet juice.
By using alternatives to road salt, freshwater can be preserved for future generations.
The
mission of Save The Water™ is to
conduct water research to identify and remove harmful contaminants in water,
and to raise public awareness about water contamination and its health impacts.
Although
Save The Water™ operates mainly in North America and follows scientific
procedures established by the United States Environmental Protection Agency,
the impact of our analytical research and water treatment technology is
universally applicable.
