Salty roads, salty rivers… on this CurrentCast..

Salt helps keep winter roads safe. But when snow melts, the salt runs off pavement and can end up in waterways.

Salty Roads

John Jackson is with the Stroud Water Research Center in Pennsylvania. In the lab, he’s studied the toxicity of salt on mayflies – a species that’s very sensitive to the environment. He says as water gets saltier...

Jackson: “We see their development times increasing, their growth rates decreasing, and then very soon after that, we also see mortality.”

He says some streams are approaching these concerning levels of salinity. So many highway departments are exploring how to reduce their use without compromising safety. You can help by not overapplying salt on sidewalks and driveways.
