Abstract A field demonstration of the Green World Science® patented process technology was performed to address acid mine drainage (AMD) at an abandoned bituminous coal mine, the Tide Mine in Center Township, Indiana County, PA. ARCADIS owns an exclusive patent license of the Green World Science® process, which can be used in situ to transform an aerobic, AMD-producing mine pool to a biologically mediated, sulfate-reducing state. The Green World Science® process treats the entire mine pool to address the source of AMD in place. The project was conducted through a grant agreement between the Blacklick Creek Watershed Association, the Pennsylvania Department of Environmental Protection's Bureau of Abandoned Mine Reclamation, and ARCADIS. In conjunction with the characterization of mine pool hydraulics through injection of a bromide tracer, the in situ treatments implemented at Tide Mine include the initial addition of alkalinity to create an environment suitable for biological activity, injection of organic carbon into the mine pool to facilitate microbially mediated metals reduction and precipitation, and injection of carbon dioxide gas into the atmosphere above the mine pool to control the dominant source of oxygen that perpetuates the AMD process. Collectively, these treatments raised the pH from a baseline of approximately 2.5 to over 6 during the demonstration period. The mine pool subsequently maintains a pH above 5 through microbially produced (i.e., bicarbonate) alkalinity. Ferric iron has been reduced to non-detect concentrations within the anaerobic mine pool, and aluminum concentrations have decreased by approximately 30%, with additional metals removal expected as the system becomes controlled by ferrous sulfide precipitation. The injection of carbon dioxide gas into the mine workings decreased oxygen concentrations above the mine pool from over 20% (ambient air conditions) to less than 5% over approximately three months, thus mitigating the source of AMD within the mine.

Title Effect of Bast Mine treatment discharge on Big Mine Run AMD and Mahanoy Creek in the Western Middle Anthracite Field of Pennsylvania Type Journal Article

Abstract The Bast Mine (reopened in 2001) and Big Mine are two anthracite coal mines near Ashland, PA, that were abandoned in the 1930's and that are now causing drastic and opposite effects on the water quality of the streams originating from them. To quantify these effects, multiple samples were taken at 5 different sites: 3 along Big Mine Run and 2 from Mahanoy Creek (1 upstream and 1 downstream of the confluence with Big Mine Run). At each site, one set of the samples was treated with nitric acid for metals survey, one set was acidified with sulfuric acid for nitrate preservation, one set was filtered for sulfate and phosphate tests, and one set was unaltered. Measurements of pH, TDS, dissolved oxygen, and temperature were made in the field. Alkalinity, acidity, hardness, nitrates, orthophosphates and sulfates were analyzed using Hach procedures. Selected metals (Fe, Ni, Mg, Ca, Cu, Zn, Hg, Pb) were analyzed utilizing flame atomic absorption spectroscopy. Drainage from the Bast Mine is actively treated with hydrated lime before the water is piped down to Big Mine Run. pH and alkalinity values were much higher at the outflow compared to those in the water with which it merged. The two waters could be visibly distinguished some distance downstream. pH values decreased, sulfate and dissolved iron increased and alkalinity was reduced to zero until the confluence with Mahanoy Creek. The high alkalinity, turbidity, TDS and calcium values in Mahanoy Creek were somewhat reduced downstream of the confluence with the much lower discharge Big Mine Run.
