Household Hazardous Waste

Household Hazardous Wastes are chemicals that are used in our daily lives and can be found in most of our homes - in the workshop, under the sink, and in the garage. These chemicals are corrosive, flammable, toxic, or reactive, and can cause damage to the environment and/or public health if they are not handled and disposed of properly. The City of Nashua and surrounding communities work together to provide opportunities for residents to safely dispose of unwanted hazardous waste. Residents of Nashua, as well as Amherst, Brookline, Hollis, Hudson, Litchfield, Merrimack, Milford, Mont Vernon, Pelham and Windham are eligible to participate in any of the events.


5 drop-off collections are scheduled for 2019 at the Nashua Public Works Garage at 9 Stadium Drive (formerly 6 Riverside Street) near the Police Department and the Conway Arena. Please carpool if possible!

There is one drop-off collection scheduled at the PELHAM Public Works Garage. The cost is $15 per vehicle, for up to 10 gallons or 20 pounds. Please carpool if possible!

  • Never mix chemicals together.
  • Never smoke or eat while handling or transporting hazardous materials.
  • Leave children and pets at home when transporting hazardous waste to a collection event.
  • At the collection site, do not leave your vehicle unless instructed to do so.
