“…Later, Bromfield (1954) noted that microbial reduction of Fe oxides may be enhanced by metabolic enzymes as mobilizers of the Fe(III) from the oxides. Further progress was accomplished with the extraction of Fe-reducing bacteria from Fe oxides in nature (Ottow, 1968(Ottow, , 1969Ottow & Klopotek, 1969;Munch & Ottow, 1977, 1982Munch et al, 1978;Rinder, 1979;Sugio et al, 1981;Onysko et al, 1984;Soljanto et al, 1985;Sand, 1989), but the ability of bacteria to modify structural Fe in phyllosilicate clay minerals was undocumented until Stucki & Getty (1986) observed that stimulation of microbial growth in the clay mineral converted structural Fe(III) to Fe(II). They measured the extent of Fe reduction in sterilized and unsterilized, nutrient-broth dispersions of ferruginous smectite inoculated with pure cultures of four different Bacillus bacteria common to soils and with the native organisms isolated from the clay mineral.…”

Virtually all 2:1 clay minerals contain some Fe in their crystal structure, which may undergo redox reaction with surrounding redox-active species causing potentially significant changes in the chemical and physical properties of the clay mineral and its surrounding matrix. This phenomenon was originally of interest mostly as a laboratory experiment using strong inorganic reduction agents, but the discovery that the structural Fe could be reduced by microorganisms in natural soils and sediments opened the way for this to become a practical method for altering the chemical and physical properties of soils and sediments in situ. The purpose of this report was to review the body of literature that has been published since the inception of this field of inquiry and to complement, update, and complete three other reviews that have been published during the intervening years. Studies of microbial reduction of structural Fe in smectites have revealed the extent of reduction, effects on chemical and physical properties, reversibility (or lack thereof) of microbial reduction, stoichiometry, possible reaction mechanism, and types of organisms involved. Some organisms are also capable of oxidizing structural Fe, such as in biotite or reduced smectite, while one appears to be able to do both. Illitic layers resist reduction by microorganisms, but this can be partially overcome by the presence of an electron shuttle compound such as anthraquinone-2,6-disulfonate, which also enhances the extent of reduction in smectites. Microorganisms may be employed as an in situ reducing agent to drive redox cycles for structural Fe in constituent clay minerals of soils and sediments, which in turn can serve as an abiotic source for redox-mediated remediation of environmental contaminants.

Controlled release bactericides affect reclamation success and provide assurance against post-reclamation water quality problems. They inhibit Thiobacillus ferrooxidans and aid in the establishment of beneficial heterotrophic bacteria necessary to support revegetation of the site. These conditions persist after the bactericide is depleted from the controlled release systems. Two coal refuse disposal areas, one in Ohio and one in West Virginia, were reclaimed using two different generations of controlled release bactericides. Case Study #1, located in Ohio, was reclaimed using first generation products with a release life of two years. Yet, six years after application, the treated area continues to have a dense vegetative cover while the untreated control area has only sparse vegetation. Water quality data from the treated area continue to show a significant improvement versus that from the control-area. Case Study #2, located in West Virginia, was reclaimed using third generation products with a controlled release life in excess of seven years. In its third year, the vegetation is lush and healthy except for the control area where vegetation is becoming sparse due to acid toxicity. The "Water quality data from the treated area corroborates these improvements and justifies the use of bactericides in reclamation.

“…Inhibiting or destroying Thiobacillus ferrooxidans bacteria can significantly slow the rate of acid production from pyritic materials. Anionic surfactants, organic acids and food preservatives (Onysko et al 1984) act as bactericides and destroy these bacteria; however, bactericides biodegrade over time and are lost because of leaching and runoff. To overcome this short • duration effectiveness of spray applications, controlled release systems to provide the bactericide slowly over a long time period were developed (Sobek et al 1985).…”

In 1984 a reclamation project was undertaken by the Ohio Department of Natural Resources on abandoned coal refuse near East Springfield, Ohio. The site was divided into two areas and each was reclaimed using standard, accepted reclamation practices. However, one area also received a controlled release bactericide treatment of ProMac Products to prevent acidification. Perforated PVC pipe drains were installed in each area at a depth of about Sm from the surface to create artificial seeps which could be monitored. Over a period of five years water quality, soil microbiology and vegetative biomass were measured and compared between the bactericide treated and untreated sides. Results from the first five years were previously reported when monitoring was terminated. Five years later, in 1994, ten years after reclamation, the site was revisited. Water quality, soil microbiology, and vegetation were analyzed to determine the long term effects. of controlled release bactericide treatment for reclamation. The site continues to show distinct differences between the bactericide treated and the untreated parcels. Especially evident are the differences in vegetation. Volunteer vegetation has become established on the bactericide treated side, whereas loss of vegetation has led to severe erosion on the untreated side.
