Household Hazardous Waste

Safe and convenient disposal is just a phone call away!

The words “hazardous waste” may conjure images in your mind of toxic green slime oozing out of huge industrial barrels. But did you know you probably have hazardous waste in your own home? Most households do. In fact, most families use about 60 toxic products! Common items like cans of leftover paint, dead batteries, cans of ant and roach spray, used motor oil, and weed killer can pollute the soil and water—and harm your trash collector—if you throw them in the garbage.

Visit the San Mateo County Department of Health or call (650) 363-4305 to find out about safe, convenient and free disposal options.
