About Household Hazardous Waste

Proper handling and disposal of hazardous materials protect our health and environment. Storing hazardous chemicals and materials in your home or garage puts you, your family, and your neighborhood at risk. It is important to minimize this risk by properly using, storing, and recycling these materials.
