Household Hazardous Waste

Household Hazardous Waste (HHW) is any leftover household product that contains ingredients that are: corrosive, toxic, ignitable (flammable) or reactive. 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.  

For items that are accepted everyday at the landfills during regular hours, please see information below.
