Soil bioventing is one of the most popular modern techniques for removing contaminants from soil. It has recently emerged as one of the most cost-effective and efficient technologies available for vadose zone remediation of petroleum-contaminated sites. This book explains in practical terms how to carry out a bioventing program. It is an interdisciplinary treatment of the subject, covering everything from basic physical and chemical properties of soils to site evaluation, project design, and post-bioventing monitoring.
The wide breadth of coverage makes Soil Bioventing useful to a large audience, including consulting firms, students, contractors, environmental managers, and anyone who is responsible for supervision of soil cleanup for regulatory reasons.

These articles discuss aerobic and anaerobic biological degradation for dehalogenating sites contaminated with pesticides and chlorinated solvents. Bench-and field-scale studies are described, as are microcosm studies, numerical simulations, and site characteristics and their effect on the stability of methanotrophic community. Methods discussed include air venting, alternative electron donors, biofilm reactors, surfactants, municipal digester sludge, iron enhancement, and sulfate reduction to improve conditions for microbial consortia.

These articles focus on methods for optimizing the effectiveness of microorganisms for biodegradation. This volume includes discussions of the biodegradation and toxicity of PAH-, PCP-, PCB-, and BTEX-contaminated soil and aqueous sediments. Both bench-scale and pilot-scale studies deal with microbial issues such as surfactant-enhanced aromatic hydrocarbon degradation, nutrient addition and bioavailability, and various dispersion techniques. Selected case studies include discussions on pre-culture and consortium biodegradation of various petroleum hydrocarbons.

This volume emphasizes pilot- and field-scale applications of bioremediation technology for petroleum hydrocarbon and chlorinated solvent contamination. Described are a variety of biological process units used to treat hazardous waste aerobic bioreactors, fluidized-bed reactors, fixed-film bioreactors for chlorinated solvent treatment, rotating biological contactors, slurry-phase bioreactors, biopile systems for treating ethylbenzene- and styrene-contaminated soils, microbial mats, and biofilters for VOC treatment.
