Vehicle wash water contains pollutants like oil, grease, heavy metals, solvents, soaps, etc. which are harmful to local streams, Lake Washington, and Puget Sound. Even biodegradable soap pollutes the environment and harms fish.
One vehicle wouldn't do a lot of damage but when you combine the wash water with everyone from Bothell and surrounding cities it causes a lot of problems downstream. A model created for Bothell residents determined that over 2,000,000 gallons of contaminated car wash runoff flows into our streams each year.
The great news is that you can help!
Join the rest of us in pledging to reduce pollution in our streams by using a commercial car wash. Can't use a commercial car wash facility? Try using a waterless car wash product or diverting the wash water to grass or gravel so it can absorb into the soil.
