Household Hazardous Waste Collection

What is Household Hazardous Waste? Chemicals typically found in homes, such as:

  • Gasoline
  • Antifreeze
  • Oil-Based Paints
  • Drain Cleaners
  • Pesticides
  • Furniture Strippers

  • Oven Cleaners
  • Disinfectants
  • Kerosene
  • Spot Removers
  • Used Motor Oil
  • Auto Batteries

Why Should You be Concerned? Some household hazardous wastes may injure you, your family, or your pets, damage the environment, or contaminate drinking water supplies.  The groundwater in your area flows to a public drinking water supply, and we’re asking for your help in keeping it clean and safe.  If you have a well on your property, you also need to think about keeping the groundwater that supplies your well clean and safe to drink.

What Should You Do? Bring your household hazardous waste to your community’s household hazardous waste collection event.  Funding assistance for these events is provided by NH Department of Environmental Services.

The State of New Hampshire Household Hazardous Waste Collection Events are scheduled in many communities throughout the year.

Please see this New Hampshire Department of Environmental Services Calendar(PDF) to find collection dates in your area.

All dates and times scheduled are subject to change so be sure to confirm the date and time by calling the contact number listed for your town. Remember, there are limits on what you can bring and how much. For complete information, you should receive a mailing from your municipality.
