Abstract
This investigation was aimed at development of laboratory techniques for use in acid pyritic-coal spoils for the purpose of identifying potential water quality problems and potential solutions to these problems. The laboratory tests or techniques involved include solution and surface characterization, FT-IR spectroscopy, automanometry, surface reactions with manganese, and treatment effectiveness in controlling acid production. These treatments include carbonates, phosphates, and organic mulches. A number of solution and surface characterization techniques were tested employing as extractants NH4Cl, NH4OAc, BaCl2 triethanolamine (TEA), and H2SO4+HCl. It is demonstrated that, based on the saturation extract test, spoils vary widely in their potential to introduce acidity and salts to runoff. This potential is not related to the potential acidity present (pyrite); rather, it is related to the age of the spoil and degree of oxidative conditions in the field. Spoils, based on the saturation extract test, appear to vary fron nonsaline to very saline.
