Comparison of total dissolved solids abundances (mg/L) reported for the Appalachian, Wind River, Anadarko, and Michigan basins in the revised database and in the Atlas of Gas Related Produced Water (Daly and Mesing, 1995). The minimum, maximum and mean contents for each basin and each dataset are presented. The greater range of values in the revised database relative to the compilation of Daly and Mesing (1995) likely reflects the inclusion of records for wells that produce oil, oil+gas, and gas; the Atlas prepared by Daly and Mesing (1995) was restricted to gas wells.
