Simulated coal leaching experiments were conducted at 25°C and 7°C, after lime treatment, and under reduced oxygen tension. Leachate from coal stored at lower temperatures, reduced oxygen and had higher pH values with lime, lower conductivities, and lower concentrations of dissolved organic carbon (DOC) and total organic carbon (TOC) than leachates from coal stored at higher temperatures and/or oxygen rich conditions. The leaching of DOC is related to acid production by chemoautotrophic bacteria. Lower concentrations of DOC in leachates from coal treated with lime can be attributed to neutralization, subsequent decreased production of acidity by autotrophic bacteria, and utilization of DOC by heterotrophic bacteria. Concentrations of aliphatic and aromatic hydrocarbons associated with the liquid fraction of leachates were not influenced by temperature or reduced oxygen concentration. Changes in the aliphatic hydrocarbon content of the coal leachates are related to metabolism by heterotrophic bacteria and/or to decreased acidity.
