Pollution Prevention Week

September 15 - 21, 2025

Each year the United States produces millions of tons of pollution and spends tens of billions of dollars dealing with it. Residents, industry, and government have significant opportunities to reduce or prevent pollution at the source through cost-effective changes in daily habits, production, operation, and raw materials use.

We often don't realize the opportunities for reducing sources of pollution because efforts are focused on treatment and disposal rather than stopping pollution at its source.

Celebrate Pollution Prevention Week!

Take time this week to reduce pollution at home, work, and play! Here are seven simple ways you can help at home: 

1. Pick up your pet waste
2. Check your vehicle for leaks
3. Call the Spill Hotline at 425-806-6750 if any pollutants go into a storm drain
4. Use compost instead of fertilizer for healthy soil
5. Take your car to a commercial car wash
6. Adopt your local storm drain to keep it free of leaves, trash, and debris 
7. Visit the Wastemobile to dispose of household hazardous waste
