Household Hazardous Waste

Many everyday household products are considered hazardous.  If not disposed of correctly, these wastes can contaminate groundwater, damage sewer lines, and impair natural resources such as lakes and rivers.

  • Anti-freeze
  • Button cell and rechargeable batteries (not alkaline)
  • Cleaners and disinfectants
  • Drain openers
  • Mercury thermometers and fluorescent bulbs
  • Oil-based paints, stains and thinners (not latex)
