Swoboda-Colberg, N., Colberg, P., & Smith, J. L. (1994). Constructed vertical flow aerated wetlands.
Abstract: In the report, wetland technology is described in which the main reactive layer is limestone gravel (rather than organic material) which is overlain by a fine gravel filter and soil. The three-year project included laboratory and field studies. Vertical aerated wetlands, simulated by columns, constructed in the field and in the laboratory, were operated during the project. The report presents a summary of results given in previous reports and summaries of results obtained using water from Butte, MT, and field studies at the Rockford Tunnel, near Idaho Springs, CO.

Abstract: Laboratory tests with synthetic acid mine water show the sealing effect of the gelatinous precipitate that forms when hydrated lime or powdered limestone is added in a simulated mine entry closed by a porous barrier.^Field tests were conducted in a recently abandoned coal mine.^Hydrated lime and limestone slurries were pumped into the mine water behind rubble barriers through 2-inch steel pipes to test the laboratory findings.^The outflow was observed at weirs attached to the ends of two 12-inch diameter drain pipes.^The results indicated that only temporary sealing of the outflow was achieved and that neutralization took place when the interior water flow conditions were favorable.

Stefanoff, J. G., & Kim, Y. K. (1994). Reduction of leachability of heavy metals in acid mine drainage. J. Environ. Sci. Health Part A Environ. Sci. Eng., 29(2), 371–388.
Abstract: The leaching characteristics of sludges from the treatment of acid mine drainage(AMD) from Iron Mountain Mine near Redding, California were compared using two different processes: caustic soda treatment and a modified lime/sulfide treatment process. The modified lime/sulfide process produced a sludge with better dewaterability characteristics than sludge from the caustic soda process. The results of the Cal WET indicated that the modified lime/sulfide process sludge had less leachability than that of sludge from the caustic soda process. Both processes could achieve a substantial reduction of heavy metals in leachate to levels below the federal regulatory limits(TCLP). For cadmium and zinc, however, neither process produced a sludge that met the requirements of the Cal WET procedure.
