Household Hazardous Waste (HHW) is any leftover household product that contains corrosive, toxic, ignitable (flammable) or reactive ingredients. Any product that contains one or more of these ingredients should NEVER be put into any of the curbside containers, down any drain, or thrown on the ground.

To keep these items from contaminating our water, land and air, they need to be disposed of properly.
