Impact of Road Salting on Freshwater Ecosystems in Baltimore, MD

A team of scientists in Maryland is uncovering the significant impact of road salting on freshwater ecosystems. Salt from de-icers enters streams and rivers, particularly in areas with extensive roads and parking lots. This salt poses a threat to wildlife, affecting both animal and plant life, while also posing risks to human health as it contaminates drinking water sources. Understanding these effects is crucial for developing sustainable practices and protecting local ecosystems from the harmful consequences of road salting.

  3. A team of scientists in Maryland are discovering that salt from de-icers is becoming a large threat to freshwater ecosystems in our area. From: http://media-2.web.britannica.com/eb-media/90/77990-004-59C9E845.jpg

  4. Not only have they been finding these salts in freshwater streams and rivers, but the highest amounts occur in watersheds with the MOST roads and parking lots!

  5. When there is snow or ice on the ground, de-icers work to melt the ice to make it safer to drive on the roads. Sidewalks are also treated with these salts to keep people from slipping on the ice.
