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 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, while conditionally exempt small quantity generator businesses may use the facility for a fee, and by appointment only.
