Household hazardous waste in Chatham, MA

The 2026 schedule, now past

Collections are held Saturdays, 9 a.m. to noon, at the Harwich Transfer Station. The 2026 dates were May 9, June 13, July 11, August 8, September 12 and October 10. All have passed as of November 2026. The card says the collections are funded by Brewster, Chatham, Harwich and Barnstable County's Cape Cod Cooperative Extension.

The county card gives no 2027 dates, and neither does the Chatham Transfer Station page. Check loveyourlocalwater.org or call the county HazMat specialist at 1-800-319-2783 in the spring. Until then, the Transfer Station takes paint at its paint shed and has a mercury shed for bulbs and thermostats.

Who qualifies and what to bring

Town residents participate for free and proof of residency is required. The town's 2025 flyer defines residents as people who own a home, own a second home, are tenants, or landlords in the town, with a driver's license showing a town address or a tax bill as proof. A second-home owner or a landlord clearing a rental can qualify; non-residents register in advance or call the county.

Bring paints and stains, lawn and garden products, household cleaners and disinfectants, auto and boat fluids and pool chemicals. The 2026 card says latex paint acceptance varies by town. Do not bring unknown or unlabeled materials, medical waste or sharps.

Cleanout days and what we haul

A cleanout often turns up half-full paint, stain and pool chemicals in a garage or shed. Keep them upright in original containers, away from heat, until the next collection. JUNKRUN does not carry hazardous waste.

What we do carry: furniture, mattresses, appliances, boxes and the rest of the pile. A mixed load is a quarter trailer $209, a half $319, three-quarters $409, a full trailer $519, with a $159 minimum. We take it from basements, garages and sheds in Chatham, South Chatham and West Chatham, with no travel fee.
