Household Hazardous Waste

Household hazardous wastes (HHW) are household items which may threaten human health or the environment and should be disposed of properly when they can no longer be used for their intended purposes.  It is illegal to throw hazardous materials in the trash.  Instead, take them to a HHW collection facility.

It is illegal to abandon hazardous substances outside the facility when it is closed.  Residents can use any of the other participating HHW collection facilities in the county.  Days and hours of operations vary.  Call (800) OILYCAT (800-645-9228) or visit the San Bernardino County Fire's Household Hazardous Waste site.   

In response to the evolving pandemic, and to protect the public from further spread of COVID-19, the Rancho Cucamonga Household Hazardous Waste Collection facility will be closed until further notice. Please contact staff at Environmental Programs if you have any questions or concerns at (909) 919-2635. Here are some great tips for storing materials until our facility opens:


  • Do keep containers tightly sealed. If there are leaks, place the leaking container into a clear plastic bag.
  • Do keep products in their original containers and keep labels on.
  • Do store HHW out of reach of pets and children.
  • Do follow storage directions provided by manufacturer.

Do Not:

  • Do not store products in food containers.

  • Do not store products near sun exposure, heat, flames, or sparks.
