Household Hazardous Waste

Household hazardous wastes (HHW) are household products that contain potentially hazardous ingredients that require special care when disposing of them. HHW’s are products that contain corrosive, toxic, ignitable, or reactive ingredients, such as oil-based paints, cleaners, oils, batteries, and pesticides. Improper disposal of HHW can pollute the environment and pose a threat to human health.

The Snohomish County HHW facility is free to residential customers, with the exception of latex based paint (see below). For loads larger than 40 gallons call prior to arrival. Conditionally exempt small quantity generator businesses may use the facility for a fee, and by appointment only. Call for fees and more information.
