Book Description

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.
