Use greener ice melt this winter!

Chemicals from ice melt eventually find their way into rivers and streams, permeating our groundwater and posing potential risks to water supplies, pets, plants, and aquatic life.

By planning ahead, you can minimize the use of de-icing chemicals and opt for safer alternatives!

Be smart about fall cleanup!

Follow these tip to help keep your local waterways clean and healthy:

  • Place raked leaves or lawn clippings in paper bags to be collected by the town.
  • Consider composting yard waste.
  • Keep paved areas and storm drains clear of leaves.
  • Keep bagged, piled and mulched leaves on natural soil, a few feet back from paved areas.
  • Ensure that your lawn service is properly disposing of yard waste.
  • Reduce excessive lawn chemical use and always follow manufacturer’s directions.
  • Call the NSP Stormwater Hotline (781) 575-0354 x300 to report dumping.

Leaves and grass clippings that are dumped or stored near waterways or paved areas add to water pollution and flooding.

The #1 cause of water pollution in the Neponset River Watershed is polluted stormwater runoff.

Polluted stormwater happens when bacteria, chemicals, and trash get washed into storm drains from impervious surfaces, like streets, driveways, parking lots; industrial sites, and construction sites.

After the polluted runoff enters our storm drains, it empties — untreated — into local streams and ponds and affects our drinking water resources, swimming, boating, fishing, wildlife, and fish habitats.

The Neponset Stormwater Partnership (NSP) is a regional cooperation and resource-sharing program in the Neponset Watershed that was formed to help reduce the water quality problems caused by polluted stormwater runoff.

NSP partners include the towns of Avon, Canton, Dedham, Foxborough, Medfield, Milton, Norwood, Quincy, Randolph, Sharon, Stoughton, Walpole, and Westwood, along with the Metropolitan Area Planning Council (MAPC).
