Passive mine drainage treatment: an effective low-cost alternative

Two prototype Passive Mine Drainage Treatment Systems have been designed and constructed in Colorado. These projects have addressed acid mine drainage from inactive coal mines. Metal removal for both systems is accomplished using simulated peat bogs composed of sphagnum moss and hypnum moss retained by loose rock check dams. Acid neutralization is accomplished using crushed limestone filled channels. Neutralization and aeration are enhanced with drop structures and waterfalls placed in the drainage channel. Preliminary water quality results show dramatic treatment effects with the PMDT system. This investigation presents cost data for design and construction of the two PMDT systems. Cost projections for periodic maintenance requirements are provided along with a suggested method for financing maintenance costs. Performance data for the first system installed are presented. 14 references, 1 figure, 2 tables.
