Technology News 407 - abandoned mine lands program TN #12: passive mine drainage treatment systems.
Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, TN 407, 1992 Oct; :1-4
Objective: Treat contaminated coal mine drainage to meet EP A and State water quality requirements. Approach: A model (fig. 1) is presented for selecting, designing, and sizing one or several passive mine drainage treatment systems that can be used in remediation of abandoned mine lands (AML). The three principal types of passive mine drainage technologies for the treatment of coal mine drainage are anarobic system, a compost wetland, and an anoxic limestone drain. The multistep approach presented here provides a simplified method to characterize the type and magnitude of the water quality problem and then to select either a single treatment system or a combination of treatment systems to address the specific site situation. Benefits: The prime benefit to be derived from using these treatment systems is the ability to meet water quality requirements of the National Pollution Discharge Elimination System. In addition, these treatment systems are more economical and maintenance free than conventional treatment with chemical additives. Applications: Passive mine drainage treatment systems are applicable to any acid or alkaline mine drainage situation. The only constraint is the available area in which to place the selected system.
