Where to take solid waste in King County

Where does it go?

Local dump/transfer stations:

Household hazardous waste

  • Household hazardous waste includes:
    • cleaning agents
    • pesticides
    • solvents
    • motor fuels
    • crankcase oil
    • oil-based paints
    • wood preservatives
    • banned or restricted-use pesticides
    • chemicals used for:
      1. home repair and remodeling
      2. auto, boat, and equipment maintenance
      3. hobby and recreational use
  • Use up hazardous household products completely before disposing of empty containers.
  • If materials cannot be used, dispose of them at a designated household hazardous waste facility such as the Wastemobile, the Factoria Household Hazardous Waste Drop-off Facility or the Seattle Hazardous Waste Facilities. Call the Household Hazards Line at 206-296-4692, Monday through Friday except holidays, between 9 am and 4:30 pm for information on these facilities.
  • Visit the Local Hazardous Waste Management Program website for additional disposal options.

Human fecal waste

  • If you suspect you have found human feces on the ground, you can pick it up the same way you would other animal waste. There is likely not a service in your local government agency that will come pick it up.
    • Get a bag, or double bag, put your hand in the bag(s), pick up the waste, wrap the bag around it, tie it off, and throw it in the garbage.
    • Don’t put it in a toilet or compost – it goes in the garbage.

Waste screening

Public Health's Waste Screening Program reviews questionable waste generated in King County that will end up as municipal solid waste.

  • The goal of the program is to keep dangerous wastes out of the solid waste stream.
  • They figure out whether a waste is dangerous or not by using information given by the generator, from lab analyses, Safety Data Sheets, and other available information.
  • Typical wastes reviewed include:
    • contaminated soil
    • sludges
    • expired or off-spec products and chemicals
    • filters
    • blasting/grinding wastes
    • empty containers
    • manufacturing wastes

Waste Screening Program staff help generators with profiling their waste and figuring out if the waste can be thrown out in the garbage.

  • For some wastes, staff will be able to give other options such as treatment, recycling, or reuse.
  • Generators should complete the online Waste Screening Application Form and submit it to the Health Department.
  • Email questions on testing requirements or further clarification to
  • To request a clearance, please fill out the Waste Screening Application Form. Contact if you have any questions.
