The White Pine and Sash company operated on the North side of Missoula between 1920 and 1996 and served as a finish mill that processed logs into trim board, window and door components and other precision woodwork.In order to preserve the wood, it was dipped in a solution of diesel and pentachlorophenol in "dip tanks". Spills and drips and drying lumber impacted soil throughout the property. On the southern end of the site, a injection well (a deep hole designed to rapidly infiltrate into the ground) infiltrated thousands of gallons of this penta mixture. This site has a record of decision (ROD) issued and is being overseen by the Montana Department of Environmental Quality.
