Hazardous Material Information

About Household Hazardous Waste

Hazardous waste can't go in the trash or down the drain. Hazardous products say CAUTION, WARNING, DANGER, or POISON on their labels. They can be harmful to humans, wildlife, and the environment if not disposed of safely.


The Wastemobile travels to communities to provide no-cost, safe disposal for household hazardous waste. Find out what items are accepted.
