Acid seeps that continue after reclamation obligate mine operators to long-term water treatment. To provide a low-cost, low- maintenance alternative, the Bureau of Mines investigated the feasibility of establishing a sphagnum moss bog as a self- perpetuating treatment system. The moss removes iron by cation exchange, oxidation of fe2+, and precipitation of iron hydroxides and sulfides. Acidity is then neutralized with limestone that, because of the iron removal step, does not become armored.
