What Is Household Hazardous Waste (HHW)?

Household hazardous wastes (HHW) are the leftover or unused portions of chemicals and products used to clean and maintain your home.  These materials are often labeled CAUTION, WARNING, DANGER, POISON, TOXIC, FLAMMABLE, or CORROSIVE.

For safety and environmental reasons it is illegal to dispose of HHW in the garbage, sewers, or storm drains. Please take these materials to the Delta Household Hazardous Waste Collection Facility.
