Hydrologic data were collected at 15 stream sites draining potential lignite areas in Calhoun, Montgomery, and Webster Counties during a period of low streamflow. The total dissolved solids ranged from 25 to 14.9 mg/L and most major ion concentrations were less and suspended sediment concentrations were less than 30 mg/L. The pH ranged from 6.7 to 8.1 units. Aluminum concentrations ranged from less than 100 to 500 micrograms per liter. Chromium and zinc concentrations ranged from 1 to 10 micrograms per gram and mercury concentrations ranged from 0.01 to 0.04 micrograms per gram in bottom material. (USGS)
