Salty runoff creating “chemical cocktails” in drinking water

Salty runoff creating “chemical cocktails” in drinking water

Last Week we wrote about the detriment that road salt can have on waterways, plants, and animals and how runoff is causing dead zones in lakes. It turns out that the story doesn’t stop there and all that salt is actually reacting with soil and water pipes to form toxic substances that can poison drinking water and harm the environment. The Revelator recently published an article examining a report published last month that found that not only is salinity increasing in many surface waters, but when you add salt to the environment it can mobilize heavy metals, nutrient pollution and other contaminants that are combining to create new “chemical cocktails” in rivers, streams, and reservoirs.

More snow, more salt, more problems

More snow, more salt, more problems

Just as one storm passed last weekend, here in D.C. (as well as across central and eastern parts of the country) we’re expected to get more winter weather. As USA Today reported, a pair of winter storms will dump snow and ice across the central and eastern U.S. over the next several days, with the second storm a potential blockbuster in some spots, with a foot of snow possible. However, with snow comes road salt to help it melt and prevent ice from forming. The downside of melting snow with rock salt is that when the snow melts most of that salt makes its way into waterways where it can harm aquatic species should enough of it accumulate. As CNN explained, salt can also change the way the water mixes and lead to the formation of salty pockets near the bottom of lakes, creating biological dead zones.
