Stormwater - Mobile Vehicle Washing


Wastes generated from mobile washing and detailing are among the many common stormwater pollutants that can degrade water quality.  Mobile detailing activities generate a variety of wastes.  Soap and cleaners contain  phosphorus that fertilize aquatic algae which can degrade water quality.  It is illegal to dispose of wash water containing pollutants to the storm drain system!
