Artesian discharges of net alkaline, ferruginous waters from abandoned underground lead-zinc mines cause considerable surface water degradation at the Tar Creek Superfund Site, part of the historic Tri-State Mining District of Oklahoma, Kansas and Missouri. Two perennial borehole discharges, identified as the lowest elevation mine water discharge points in the district, have flowed unabated for almost 30 years and considerably degraded the physical, chemical and biological integrity of a first-order tributary to Tar Creek. Based on a comprehensive water quality and quantity characterization study, a large multi-cell passive treatment system was designed to receive approximately 1000 L/minute of mine water flowing from these abandoned boreholes (pH 5.95±0.06, total alkalinity 393±18 mg/L CaCO 3 , total acidity 364±19 mg/L CaCO 3 , Fe 192±10 mg/L, Zn 11±0.7 mg/L, Cd 17±4 ug/L, Pb 60±13 ug/L and As 64±6 ug/L). The objectives of this project include: i) remediation of polluted mine waters to acceptable quality for maintenance of the receiving water body aquatic community, ii) demonstration of the first mine water treatment facility of any kind in the Tri-State Mining District, and iii) technology transfer to speed application of this technology to other locations. The passive treatment system includes an initial oxidation pond followed by parallel treatment trains (to facilitate research and experimentation) consisting of aerobic wetlands, vertical-flow bioreactors, re-aeration ponds (with active aeration via wind and solar power) and horizontal-flow limestone beds. Waters from the parallel trains are recombined in a polishing wetland prior to final discharge. Total design surface water elevation change in the entire system is approximately 1.8 m. Prior to system implementation, the abandoned boreholes required rotosonic over-drilling to establish hydraulic control. In addition, diversion of storm water flows from an approximately 470-ha upgradient watershed was necessary. During construction, a third mine water discharge was discovered and incorporated into the design. This system represents a state of the art ecological engineering research site for passive treatment of mine waters.

“…The high concentrations of multiple ecotoxic metals of interest in the sludge present a possible reclamation opportunity or if mishandled an environmental hazard. Iron has been economically recovered from standard passive treatment systems for years and Mn recovery has recently begun (Hedin, 2003; Denholm et al, 2008). It is important to note that the sludge was not dewatered before sampling and analysis.…”

Novel Passive Co‐Treatment of Acid Mine Drainage and Municipal Wastewater

A laboratory-scale, four-stage continuous-flow reactor system was constructed to test the viability of high-strength acid mine drainage (AMD) and municipal wastewater (MWW) passive co-treatment. Synthetic AMD of pH 2.6 and acidity of 1870 mg L(-1) as CaCO3 equivalent containing a mean 46, 0.25, 2.0, 290, 55, 1.2, and 390 mg L(-1) of Al, As, Cd, Fe, Mn, Pb, and Zn, respectively, was added at a 1:2 ratio with raw MWW from the City of Norman, OK, to the system which had a total residence time of 6.6 d. During the 135-d experiment, dissolved Al, As, Cd, Fe, Mn, Pb, and Zn concentrations were consistently decreased by 99.8, 87.8, 97.7, 99.8, 13.9, 87.9, and 73.4%, respectively, pH increased to 6.79, and net acidic influent was converted to net alkaline effluent. At a wasting rate of 0.69% of total influent flow, the system produced sludge with total Al, As, Cd, Cr, Cu, Fe, Pb, and Zn concentrations at least an order of magnitude greater than the influent mix, which presents a metal reclamation opportunity. Results indicate that AMD and MWW passive co-treatment is a viable approach to use wastes as resources to improve water quality with minimal use of fossil fuels and refined materials.

“…because the Mn is chemically displaced by Fe 2+ , and precipitates of Fe and Al interfere by plugging the bed. Denholm et al (2008) successfully recovered an Mn-rich sludge from a limestone bed that had been removing Mn for several years. A small pond was excavated in the bed, and the Mncoated limestone was agitated below water level in the pond inside a perforated drum mounted on an excavator.…”

Abstract. This report updates the review of passive treatment prepared by the Acid Drainage Technology Initiative (Skousen et al., 1998). Important advances since that report include: 1. Measured and calculated acidities are net acidities that are robust measures of this parameter. 2. Removal rates of Fe at pH>5 can be enhanced by CO 2 degassing, by catalysis by solid Fe phases and by specialized aerators; at pH<5, low pH Fe oxidation by bacteria can be helpful in treating high-Fe acidic discharges. 3. For low-Fe-Al AMD, oxic limestone drains can be effective for treatment, but effectiveness declines over years owing to accumulation of precipitate. 4. For high Fe or Al AMD, limestone beds with timed flushing devices can remove large amounts of metals, though eventual cleaning of the limestone may be needed. 5. Addition of limestone sand or lime to streams can be a cost-effective method of restoring watersheds 6. Vertical flow ponds (VFP's, SAPS) can be sized using a loading factor of 25-35 g of acidity/m 2 /d. 7. Manual flushing of VFP's removes only a few percent of accumulated Al precipitate, but timed flushing can be much more effective. 8. Common problems of VFP's include inadequate size, accumulation of Fe precipitate on compost, deterioration owing to Al coatings, and construction defects. 9. Sulfate reduction in passive systems involves a complex community of microbes, with long-term rates dependent on cellulose degrading microbes. Mixtures of fresh organic matter with high-cellulose material appear to provide good performance in lab tests, but more data on longer-term behavior is needed. 10. Sulfate-reducing bioreactors process Al better than older VFP's. 11. Steel slag and chitin hold promise for effective treatment of AMD. 12. A relation for sizing of limestone beds for Mn removal has been developed. 13. Fe precipitate from sludge is being successfully sold for pigment production, and Mn-rich concentrate has been recovered from limestone beds. 14. A revised flow chart for selection of treatment method has been prepared, and the AMDTreat computer program allows easy costing of passive treatment.
