Bioremediation techniques for treating metals-contaminated soil and water are in an emerging state of development. Unlike organic compounds that can be broken down into harmless compounds such as CO2 and water, metals and their salts generally inhibit biological activity. They must be converted into more complex states, be sorbed, or undergo valence state changes before biodegradation by activated sludge treatment or other complex reactions such as air stripping can occur.

This book introduces various treatment technologies and options for the bioremediation of metals. The chapters, written by researchers and practitioners from North America and Europe, represent the most recent compilation of state-of-the-art techniques and methods for metals biotreatment.

These topics and more are addressed:

• Biological treatment options for metals
• Passive bioremediation of metals from water using reactors or constructed wetlands
• Bacterial chromate reduction and product characterization
• Microbial removal of heavy metals and sulfate from contaminated groundwaters
• Combined removal of arsenic, VOCs, and SVOCs from groundwater using an anaerobic/aerobic bioreactor
• Recycling of copper flotation tailings and bioremediation of copper-laden dump sites
• Feasibility of in situ chemical oxidation of refractile chlorinated organics by H2O2-generated oxidative radicals
• Implementation of microbial mats for bioremediation
• Mercury microbial transformations and their potential for remediating a mercury-contaminated site #
• Remediation of mining water with microbial mats
