Common substances can pollute Plymouth’s lakes, streams and wetlands. When it rains, runoff carries pollutants into these water resources through the city’s storm sewer system.

Grass clippings and pet waste are two of the most common contributors to algae growth in lakes and wetlands. Both harm water quality.

The Minnesota Pollution Control Agency, in accordance with the federal Clean Water Act, requires the city to develop a Storm Water Pollution Prevention Program (PDF). The plan includes projects, practices and programs that will help prevent pollution from entering the city’s surface water resources.
