Household Hazardous Waste

Welcome to the

Household Hazardous Waste

Web Site



CLICK HERE for our TENTATIVE 2024 HHW Collection Schedule!


Attendees MUST:

  • stay in their vehicles
  • place their waste in the trunk or truck bed - not hand it out the window or have it in their back seat


The Regional Planning Commission recognizes the great benefit to keeping toxic chemicals out of our water supplies by providing management options for unwanted chemicals like cleaning products, paint and paint related products, automotive fluids, and much more.

2015 was the last year we collected medicines with DHMC at our HHW collection as there are many other options every day at police stations around the region.  Visit for a list of locations and other information about keeping your family safe with proper storage and disposal of medicines.

 Thanks for checking us out!

People try the Nontoxic Cleaners and LIKE them!

After talking to Intern, Noah El Naboulsi this summer, people provided testimonials after trying the nontoxic cleaners at home.  Check them out:

  • My dog has gotten sick in the past from licking floor cleaners off the floor so a mix of only vinegar and water is great.
  • Thank you for doing this work!  It is so important and we need to continue to rally together to make a change!
  • I’m gonna annoy all the people in my dorm this year about what you told me at the farmer’s market.  Scary stuff, but I’m glad you are teaching people.  Thanks!
