HazWaste Days Collection Event

What is HazWaste Days?

Each year since 1993 (with the exception of 2017) the Missoula Valley Water Quality District has held a Household Hazardous Waste Collection Event.  This years event was Sept 21st and 22nd and was a huge success.  If you missed us this year's event and have products in your home you can check out the year-round option guide listed below or our next collection event will be in September 2019.

Many unwanted hazardous and toxic materials are accepted at this event from Missoula County Residents for no charge, including oil-based paints and stains, paint thinner, degreasers, gasoline, other flammable liquids, aerosol paints, fertilizer, non-alkaline household batteries (alkaline batteries can be thrown away), used motor oil (courtesy of Republic Services -up to 15 gal.), antifreeze and up to 6 fluorescent tubes (no bulbs -- see year-round options, below). Mercury fever thermometers are also accepted at HazWaste Days for free.

Items accepted for a fee include pesticides, caustics, strong acids and chlorinated solvents. The fee charged covers approximately 25% of our costs for shipping and disposing of the waste.

Businesses and out-of-county residents will be charged our costs for disposal of all waste.

Since we currently only offer this event once a year, please take a look at our Year-round Options Guide if you have waste that you are unable to keep until the next event.  Please note that their may be a charge for disposing of items that are normally accepted for free at the annual event.
