The majority of electricity in the United States is generated from burning coal, due mainly to its abundance and low cost. As coal is mined a significant amount of waste rock material, or coal refuse, is generated. This coal refuse is disposed of in large, highly compacted piles on the mine site and must be stabilized and revegetated in accordance with the Surface Mining Control and Reclamation Act (SMCRA). Coal refuse generally lacks any essential plant nutrients, has a low water holding capacity, and can produce acid mine drainage (AMD). One method to reclaim coal refuse piles is to use fly ash as a liming agent. Fly ash is the noncombustible mineral component of coal that rises with the flue gases after coal combustion and is captured by various dust collecting systems. Previous studies have focused on bulk blending of fly ash with the refuse. While this may be the preferable way to codispose the two materials, it is difficult to practically execute. A better representation of field conditions is a pancake layer of ash above the refuse. This leaching column study will compare the two methods by evaluating the leachates over the course of 6 months. An emphasis will be placed on the leaching of the trace elements As, Se, Mo, and Cr.
