“…Results from the study suggest that ryegrass can be used in aided phytostabilization for acidic mine-contaminated soils and that MSWC, and to a lesser extent SS, were effective in the in situ immobilization of metals and improved soil chemical properties and increased plant biomass. Two column experiments were conducted to assess the suitability of an organic carbon (OC)-based reactive mixture and an iron(0)-bearing organic carbon (FeOC)-based reactive mixture to treat simulated groundwater containing 380 ppm sulfate, 5 ppm arsenic, and 0.5 ppm antimony (Guo and Blowes, 2009 Sulfide-and carbonate-rich mine tailings with near-neutral pH pore water were amended with <1 dry wt.…”

A review of literature published in 2009 and early 2010 on research related to the production of acid mine drainage and/or in the dissolution of minerals as a result of mining, with special emphasis on the effects of these phenomena on the water quality in the surrounding environment, is presented. This review is divided into the following sections: 1) Site Characterization and Assessment, 2) Protection, Prevention, and Restoration, 3) Toxicity Assessment, 4) Environmental Fate and Transport, 5) Biological Characterization, and 6) Treatment Technologies. Because there is much overlap in research areas associated with minerals and mine drainage, many papers presented in this review can be classified into more than one category, and the different sections should not be regarded as being mutually– exclusive, nor should they be thought of as being all– inclusive.

Zhovty Vody city, located in south-central Ukraine, has long been an important center for the Ukrainian uranium and iron industries. Uranium and iron mining and processing activities during the Cold War resulted in poorly managed sources of radionuclides and heavy metals. Widespread groundwater and surface water contamination has occurred, which creates a significant risk to drinking water supplies. Hydrogeologic and geochemical conditions near large uranium mine tailings storage facility (TSF) were characterized to provide data to locate, design and install a permeable reactive barrier (PRB) to treat groundwater contaminated by leachate infiltrating from the TSF. The effectiveness of three different permeable reactive materials was investigated: zero-valent iron (ZVI) for reduction, sorption, and precipitation of redox-sensitive oxyanions; phosphate material to transform dissolved metals to less soluble phases; and organic carbon substrates to promote bioremediation processes. Batch and column experiments with Zhovty Vody site groundwater were conducted to evaluate reactivity of the materials. Reaction rates, residence time and comparison with site-specific clean-up standards were determined. Results of the study demonstrate the effectiveness of the use of the PRB for ground water protection near uranium mine TSF. The greatest decrease was obtained using ZVI-based reactive media and the combined media of ZVI/phosphate/organic carbon combinations.

“…Several studies have mentioned the role of different carbon sources on SRB growth (Das et al 2012;Martins et al 2011;Singh et al 2011;Cheong et al 2010;Zhao et al 2010;Costa et al 2009;Das et al 2009a, b;Guo and Blowes 2009;Boshoff et al 2004). On contrary, little information is available about the role of nitrogen source on the growth of SRB.…”

Suitability of different growth substrates as source of nitrogen for sulfate reducing bacteria

et al. 2015

Sulfate reducing bacteria (SRB) mediated treatment of acid mine drainage is considered as a globally accepted technology. However, inadequate information on the role of nitrogen source in the augmentation of SRB significantly affects the overall treatment process. Sustenance of SRB depends on suitable nitrogen source which is considered as an important nutrient. This review focuses on the different nitrogen rich growth substrates for their effectiveness to support SRB growth and sulfate reduction in passive bioreactors. Compounds like NH4Cl, NH4HCO3, NO3 (-), aniline, tri-nitrotoluene, cornsteep liquor, peptone, urea, and chitin are reported to have served as nitrogen source for SRB. In association with fermentative bacteria, SRB can metabolize these complex compounds to NH4 (+), amines, and amino acids. After incorporation into cells, these compounds take part in the biosynthesis of nucleic acids, amino acids and enzyme co-factor. This work describes the status of current and the probable directions of the future research.
