ROBINS AIR FORCE BASE, Ga. – Around this time of year, we start to notice the grease, oil, pollen, dirt and grime that collect on our cars over the winter and early spring. This is the time many of us pick up our hoses and soap buckets and give our vehicles a much-needed washing. It is great to have a clean, fresh start. However, it is important to keep in mind the impacts that “do it yourself” car washing has on our local waterways and environment.
When we wash our cars at home, the wash water flows down driveways, parking lots, and streets to the stormwater system. The stormwater system discharges directly to rivers, lakes, and streams without treatment. Pollutants that accumulate on vehicles may include gasoline, residue from exhaust fumes, oil, grease or heavy metals. In addition, soaps that are used for car washing can contain pollutants, which affect water quality and aquatic life.
Under the Houston County Water Resources Protection Ordinance, there are no prohibitions against residential car washing. However, utilizing commercial car-washing facilities can reduce overall water consumption and the concentrations of pollutants in our stormwater.
Car washing facilities must comply with regulations that are designed to protect the quality of water. Commercial car washes usually filter and reuse their water and eventually direct it to a water treatment plant before it goes back into our water resources. These facilities also help to save water by using approximately 60% less water than a car wash at home. Next time you need to give your car a refresh, consider using a local car wash to save water and protect the environment.
