Wash Your Car – Without Harming Streams
Take your car to a commercial car wash. Commercial car washes are required to trap grease, oil, grime, soap and dirt onsite. They then send this filtered wash water to the Water Pollution Control Plant, where it is further cleaned and treated.
Why is it better not to wash your car on the driveway? Wash water can run off into the street, enter a storm drain, and flow into a neighborhood stream, affecting fish and other aquatic life. Even if you can position your car so that wash water would flow to a grassed or landscaped area, you may not want the brake dust, grease, and other substances on your car in your yard.
White sudsy water in a stream is usually associated with car washing, pressure-washing or other detergent discharge. If you see this in an Arlington stream, call 703-558-2222 to report it right away.
