Pollutant Sources

Under Construction Sign


During construction activities such as:

  • Grading and demolition create potential pollutants that can migrate off the site and harm waterways. Sediment is one of the main pollutants of concern.
  • When it rains, stormwater washes over the loose soil on a construction site, along with any materials and products stored outside. As stormwater flows over the site, it can pick up pollutants.
