While natural processes have been remediating acidic water exhibiting elevated dissolved metals for eons, engineers and scientists have been trying to mimic nature in the treatment of mining influenced water for only about 50 years. The technical community has adopted the term “passive treatment” to describe the technology. The design of passive treatment systems is based on the application of multidisciplinary engineering sciences including biogeochemistry, hydraulics, physics, microbiology, and agronomics to name a few. Consequently, there are many opportunities to not quite “get it right” in passive treatment system design, construction, and operation. Fortunately, Mother Nature can be quite forgiving and sometimes a design or operational hiccup can reveal new insights. The case histories presented in this review reflect the learning experiences of a mining engineer whose technical education barely touched on the fundamentals of passive treatment system design. Early system designs were often based on the findings of other practitioners who were gracious enough to share their knowledge at pre-internet conferences and in easy-to-understand publications. Indeed, the current state of practice of passive treatment design rests on the shoulders of a few brilliant pioneers, most of whom are still with us. This review continues the sharing tradition. The common thread among the mini-case histories discussed is that most are from bench- and pilot-scale testing programs, which reinforces the benefits of small-scale testing as an economical way to accumulate valuable lessons learned experience with minimum risk. Key takeaways from the lessons learned by this author are: ● Biochemical reactors (BCRs) can be overloaded, but only for a short time to avoid permanent harm to the microbial community. ● Other metal removal processes can substitute for sulfate reduction in overloading situations but the beneficial effects may be reversible. ● Media material substitution risk in full scale construction can be lessened if bench or pilot data is available. ● BCRs are feasible in cold climates. ● The age of woody material (fresh vs. moldy) in BCR media is inconsequential. ● Allow plants to grow on BCR surfaces with caution. ● Excessive aluminum concentrations do not cause BCR media to plug. ● Metal adsorption to manganese oxide coatings may be a viable alternative to sulfide precipitation in BCRs. ● Mixing bypassed mining influenced water with BCR effluent may offer benefits in a freshet. ● A test failure may be due to an improper design and should not condemn the passive treatment concept. ● In final design and construction, avoid deviating from the bench- or pilot-scale test conditions.

Mitigation of Metal Mining Influenced Water is the "how to fix it" volume in a series of six handbooks on technologies for managing metal mine and metallurgical process influenced water. Unlike other texts that focus exclusively on acid drainage from coal mines, this comprehensive series examines both acidic and neutral pH waters from metal mining and metallurgical processes that may impact the environment. The authors take a holistic approach by considering all aspects of the mine life cycle, from planning and design to closure. In this book you'll learn how mining influenced water concerns can be prevented or reduced by disrupting the geochemical relationship that contributes to the release of metals and/or acidity. Industry experts provide insights into understanding a mine's physical environment and how it can influence waste and drainage quality. They outline key issues designers must address, including involving stakeholders who may be affected long after the mine closes. Case histories offer valuable planning and design considerations by illustrating what works and what doesn't. You'll also benefit from a thorough examination of mitigating technologies in a host of mining and processing situations, as well as the latest arsenal of waste treatment options. Mitigation of Metal Mining Influenced Wateris a must-read for planners, regulators, consultants, land mangers, students, researchers, and others concerned about the environmentally sound management of metal mine and metallurgical processing wastes and drainage quality.
