Runoff from Missoula properties and streets collect in storm water inlets, flowing directly to our aquifer, rivers, and streams. This runoff can carry pollutants: oil from our cars, fertilizer from our gardens, animal waste, spilled chemicals, trash left on the ground, sediments, and anything else small enough to be picked up by storm water. These pollutants affect our local industries and economies downstream. Together, we are working to reduce these pollutants and keep our rivers and streams safe and clean.
