Stewart, D., Norman, T., Cordery-Cotter, S., Kleiner, R., Sweeney, E., & Nelson, J. D. (1997). Utilization of a ceramic membrane for acid mine drainage treatment. Tailings and Mine Waste '97, , 453–460.
Abstract: BASX Systems LLC has developed a treatment system based on ceramic membranes for the removal of heavy metals from an acid mine drainage stream. This stream also contained volatile organic compounds that were required to be removed prior to discharge to a Colorado mountain stream. The removal of heavy metals was greater than 99% in most cases. A decrease of 30% in chemicals required for treatment and a reduction by more than 75% in labor over a competing technology were achieved. These decreases were obtained for operating temperatures of less than 5 degrees C. This system of ceramic microfiltration is capable of treating many different types of acid mine waste streams for heavy metals removal.

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.
