Facilities that generate ready-mixed concrete, crushed stone, or sand and gravel can impact surface water and ground water quality through runoff and chemical storage, use, and disposal practices. Stormwater runoff from these facilities can have a significant impact on water quality by contributing sediment and other pollutants to surface water. Diesel fuel, solvents, and oil are used on site and have the potential to impact ground water and surface water if proper handling, storage, and disposal practices are not used.
