Each year since 1993 (with the exception of 2017) the Missoula Valley Water Quality District has held a Household Hazardous Waste Collection Event. This event will be held Sept 21st and 22nd (Friday and Saturday)at the Missoula City Shops, 1305 Scott St . Friday’s hours will be from 9 am until 5:30 pm and Saturday’s hours will be 9 am until 4 pm.
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 and you will receive a free digital thermometer in exchange!
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.
