Fifty-two grab samples of bottom sediment in settling ponds were obtained at 17 surface coal mines in the eastern and mid-western US. A series of laboratory extraction procedures were designed to simulate a wide range of possible natural conditions. There was generally a consistent order of extractability for all the extracts performed. At the mines where chemical treatment was used to neutralise mine drainage, Mn was the most mobile and Fe and Al the least mobile of the metals considered. At mines not using chemical treatment, Ni, Zn and Co were among the most mobile and Fe, Al and Cr the least mobile of the metals studied. Two stepwise regression procedures were used to suggest a ranking of independent variables that influence extractable metals. In general, the total amount of metal present was most important in determining metal extractability in the buffered extract at a mine using chemical treatment. Variables related to the natural acidity or alkalinity of the sediment and element interrelationships were important in the other extracts. It appears possible to predict extractable metals using simple regression models.
