BLACKSBURG, Virginia, April 22, 2021 (ENS) – “Inland freshwater salt pollution is rising nationwide and worldwide, and we investigated the potential conflict between managing freshwater salt pollution and the sustainable practice of increasing water supply through the addition of highly treated wastewater to surface waters and groundwaters,” said Stanley Grant, professor of civil and environmental engineering in the Virginia Tech College of Engineering.
“If we don’t figure out how to reverse this trend of salt pollution soon, it may become one of our nation’s top environmental challenges.” Grant and his collaborators have published their findings in the journal “Nature Sustainability.”

When winter storms threaten to make travel dangerous, people often turn to salt, spreading it liberally over highways, streets and sidewalks to melt snow and ice. A new study warns that introducing salt into the environment whether it’s for de-icing roads, fertilizing farmland or other purposes releases toxic chemical cocktails that create a serious and growing global threat to our freshwater supply and to human health.

However, a new study led by Sujay Kaushal of the University of Maryland warns that introducing salt into the environment whether it’s for de-icing roads, fertilizing farmland or other purposes releases toxic chemical cocktails that create a serious and growing global threat to our freshwater supply and to human health.

Water touches virtually every aspect of human society, and all life on earth requires it. Yet, fresh, clean water is becoming increasingly scarce one in eight people on the planet lack access to clean water. Drivers of freshwater salt pollution such as de-icers on roads and parking lots, water softeners, and wastewater and industrial discharges further threaten freshwater ecosystem health and human water security.
