Portsmouth, NH Department of Public Works Hosts Household Hazardous Waste Collection Day on October 24, 2026

September 24, 2026

Portsmouth, New Hampshire – The City of Portsmouth Department of Public Works will hold its 
semiannual Household Hazardous Waste Collection Day on Saturday, October 24, 2026 at the Public 
Works facility at 680 Peverly Hill Road. Residents of Portsmouth, New Castle, and Newington are 
encouraged to bring household chemicals for safe disposal between 8 am and 12 noon.


Collection Day is organized as a drive-through service. Residents remain in their vehicles and pull
through the Public Works garage, where staff will remove disposable items from car trunks. 
Residents will be asked to show proof of residency for survey purposes, in compliance with EPA 
requirements.


Household hazardous waste collection helps safely dispose of items that can harm residents' health, 
the environment, and drinking water supplies.

Items that qualify for collection include the following:

  • From the yard: fertilizer with pesticides or fungicides, insect spray, lighter fluid, pest 
    strips/traps, pesticides, poisons, and pool chemicals.
  • From the garage: acids, car waxes/polish, creosote, driveway sealer/tar, flea powder, 
    gasoline, radiator fluid, and roofing tar.
  • From the house: bathroom cleaner, disinfectants, furniture polish, metal polish, mothballs, 
    oven cleaner, photo chemicals, rug cleaner, and wood strippers.
  • From the workbench: brush cleaner, corrosives, lead and oil-based paint/stain/finish, rust 
    preventive solvents, thinner/turpentine, and wood preservatives.

Items that do not qualify include empty containers for household items which may be disposed of in 
the regular trash collection, explosives, asbestos, medical waste, or latex paint. To prepare latex 
paint for regular disposal at the Recycling Center, solidify the paint by adding kitty litter, sawdust,
SpeediDri, or open the can to allow the liquid to dry out completely before disposal.
