Did you know grass clippings and yard waste can contribute to stormwater pollution? 💧
Grass clippings themselves are not a direct chemical pollutant, but they can significantly impact water quality if they enter stormwater systems or surface water.
The main concern is nutrient loading, especially nitrogen and phosphorus, which can trigger algal blooms and reduce dissolved oxygen in water bodies.
When grass clippings, leaves, and other landscaping debris are left on driveways, sidewalks or streets, they can wash into storm drains or directly into nearby waterways.
As the yard waste decomposes, it releases excess nutrients such as nitrogen and phosphorus into the water.
These excess nutrients can fuel algae growth, reduce dissolved oxygen levels needed by aquatic life, and contribute to poor water quality conditions in the waterways that support local ecosystems, drinking water resources and the outdoor spaces we enjoy.
These simple actions can help minimize impacts to our local waterways:
💧Compost or properly dispose of yard waste
💧Sweep debris back onto lawns instead of washing it away
💧Use grass cycling or mulching practices when possible
Cleaner streets help support cleaner creeks, lakes, and waterways for everyone to enjoy. 🌊🐟
