In Situ Aeration: Air Sparging, Bioventing, and Related Remediation Processes (Proceedings from the Third International in Situ and On-Site)

This volume includes laboratory studies, field demonstrations, and aeration-related technologies that support remediation at hydrocarbon-contaminated sites. The relationship of site characteristics (soil temperatures and permeability, availability of nutrients, etc) to the rate of contaminant degradation is addressed, and ways to enhance natural site conditions are explored. Techniques include pressure de watering and use of foams, oil aprons, and microbial dispersions. Numerical modeling and design parameters for in-well circulation, wind-powered bio-venting, and other systems are discussed.
