Abstract
The results of analyses of surface waters collected from a variety of
locations in west-central Indiana indicate extensive contamination by
acidic mine drainage. These samples had pH values as low as 2.1 and to
tal iron concentrations as high as 1200 mg l(-1). The speciation of ir
on, expressed as the ratio [Fe(II)]/[Fe(III)] ranged from 0.08 to 8.27
. Measured lead concentrations were as high as 811 mg l(-1). In additi
on, the concentrations of nitrate and sulfate ions were as high as 359
and 624 mg l(-1) respectively.
