Contamination of surface water by conglomerate mixtures of metals is a significant health problem in aquatic environments near mining and metal (tannery) processing operations. Metals, such as hexavalent chromium (CrVI), manganese (Mn), lead (Pb), selenium (Se), and zinc (Zn) have been shown to occur at elevated levels in many near-shore environments (Capone et al., 1983). In situ bioremediation of these metals has been suggested as a mechanism to alleviate the presence of these contaminants. In this regard, our laboratory has examined the bioremediation and removal of various individual heavy metals from soil and water, in simulated ponds using a mixed microbial ecosystem. In these experiments 80–90% of the metals examined were reduced and recovered from both soil and water in the biomass formed on the pond surface (Ibeanusi et al., 1989; Archibold et al., 1989; Bender et al, 1987).
