Water is our most valuable shared resource and together we can keep it
that way for generations to come.
Hazardous Waste Disposal Information

Every year the Missoula Valley Water Quality District sponsors Haz Waste Days. It’s an opportunity for you to do your part to help protect Missoula’s drinking water. Paint thinner, lead, acid batteries, degreasers, solvents, aerosol paints, lubricants and limited amounts of used motor oil, antifreeze and highly toxic materials such as pesticides are accepted.

The following hazardous items may be disposed of year-round
at the following locations.

Waste Oil – Republic Services (543-3157) will collect up to 2 gallons in clear plastic jugs with weekly trash collection. Do not mix antifreeze or solvents.

Waste Oil and Antifreeze – Contact the Missoula Valley Water Quality District at (406) 258-4890 for more information.

Automotive Batteries – May be disposed of at most retail outlets.

Nickel-Cadmium Batteries – Stores like Best Buy, Home Depot & Lowes will often accept batteries for recycling.

Fluorescent Bulbs – Palmer Electric (543-3086)

Pharmaceuticals – To dispose of both prescription medicines and over-the-counter drugs:

• Contact your local pharmacist to see if you can return unwanted portions.

• Contact the Missoula Valley Water Quality District (406-258-4890) prior to Haz Waste Days to see if they will accept the waste.

• Dispose of the waste in your household trash:

  • Keep products in their original containers with labels. Remove patient information for privacy.

  • Add a small amount of water if it is a solid drug. Add kitty litter, sawdust or flour if it is a liquid drug.

  • Recap and tape the lid if it is not a childproof container. Then double seal the container in a plastic, sealable bag or a brown cardboard box to prevent easy identification and breaking.

  • Place in trash receptacle as close to garbage pickup as possible.
