Protected Aquifers For oil and gas wells • Freshwater (less than 1,000 mg/l total dissolved solids, TDS), and • Usable-quality water (less than 3,000 mg/l TDS, waters known to be used, and waters identified by the Texas Water Development Board for use in desalination) For saltwater injection wells in addition to the above • Underground source of drinking water (less than 10,000 mg/l TDS)
