The Impact

Litter and chemicals from our home can pollute waterways and be toxic to aquatic life. Household hazardous waste includes products that can cause algal blooms, damage aquatic ecosystems, and harm wildlife living in and drinking from our streams and creeks.

What do I do with hazardous materials?

Whether you need to get rid of used motor oil, paint, solvents, or fertilizer, please recycle or properly dispose of these products. By responsibly disposing of these items, you are keeping them from accidentally ending up in our streams and negatively impacting aquatic life.
