| Professional car washes remove soap and toxins from car washing water, and pipe it into a treatment facility. |
| Storm water contamination occurs when a car is washed over a paved surface instead of at a professional car wash. Oil, dirt, and grime, along with detergent, petroleum, and wax are allowed to flow down the storm drain and into the nearest body of water. Unfortunately, most people do not know that discharging anything other than clean, cold water into Washington state waters is, in fact, illegal. |
