Collision repair shops generate various types of waste that can affect water quality, such as used absorbents, waste antifreeze, brake fluids, used paints, paint booth filters, paint solvents and thinners, used fluorescent lamps, used batteries, used part washer solvents, used shop towels/rags, scrap metal, used oil, and used tires. Many of these wastes may be considered hazardous and can impact surface and ground water quality. Spraying, blasting, and sanding activities performed by auto body shops can contaminate surface and ground water if not properly contained. Discharges of untreated wastewater or contaminated stormwater can impact surface and ground water quality, especially if floor drains are connected to shallow injection wells. Aboveground and underground storage tanks can be used at collision repair shops and both have the potential to leak hazardous material that can impact water quality.
