Description: A number of authors have reported that DSC in the Tuscaloosa Group in southwestern Alabama is high (Alverson, 1970; Tucker and Kidd, 1973; Miller, 1990) However, there are few published numbers (see Tucker and Kidd (1973; their table 3 in which they report one calculated DSC for the Tuscaloosa Group of 151,000 mg/L). For the GIS, we used a map of Miller (1990), which shows the portion of southwest Alabama, Tuscaloosa Group (Black Warrior River aquifer), in which formation waters are more than 10,000 mg/L
