Salt Runoff Chokes Baltimore Streams

Baltimore County's winter salting practices are leading to significant environmental challenges, as runoff carries excessive salt into local streams. Monitoring of Scott's Level Branch reveals salinity levels mirroring those found in the Chesapeake Bay, impacting the delicate freshwater ecosystem. This situation, ongoing for nearly two decades, poses a threat to native plants and animals, including vulnerable trout populations.

While essential for road safety, the effectiveness of salt diminishes beyond certain concentrations. Baltimore County's Department of Environmental Protection and Sustainability is promoting reduced salt usage. Agencies are implementing computerized systems to prevent oversalting, and residents are advised to apply salt sparingly, using alternatives like sand, to mitigate environmental damage.

Small changes in winter habits can yield substantial improvements for stream health. By reducing salt application, Baltimore County aims to reverse the decline in aquatic species and restore its waterways. The goal is to protect local biodiversity, allowing species to return if ecosystem conditions improve.
