The mission of the Hazardous Waste & Water Quality Program is protecting our drinking water supply,  an unconfined sole-source aquifer, through public education and regional collection programs of hazardous materials.


We know it’s not easy determining which household products can be disposed of in your regular trash and what is hazardous. We’ll help you identify responsible and convenient disposal options to prevent potential harm to the environment and your home. We’re here to help with:

Household Hazardous Waste

2020 HHW Collections Schedule

How do I get rid of?

Info on the safe disposal of sharps, flares, liquid mercury, and unwanted medications.

Waste Reduction and Recycling

Solutions to reduce trash and increase recycling.

Water Quality & Well Water

Facts sheets, information, and advice for safe drinking water.


Small businesses needing to dispose of hazardous waste are encouraged to participate at any collection scheduled throughout Cape Cod.

Barnstable County coordinates a regional collection program in collaboration with individual municipalities. Should you require additional disposal services, you can participate, at cost, through any town’s scheduled collection.

What Small Businesses Need to Know

  • Registration is required.  Call at least 2 weeks ahead of collection date to register and discuss the type and quantities of materials you plan to bring.  (Note:  Barnstable County’s contractor cannot accept acutely hazardous materials).  Upon registration, we will send you a bill of lading and the fee for disposing materials.
  • Disposal fees are the same as the cost paid by the town.  No additional fees or markups are added.
  • Contact information, current collections schedule, and registration information (coming soon).
