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 ...
The problem of aquifer contamination remains one of the greatest challenges facing environmental scientists and engineers. Air sparging, a technique unknown until recently, has emerged with increasing application frequency as an alternative to both the pump-and-treat technology and conventional in situ bioremediation for treating this problem. ...
The articles in this collection discuss genetic engineering, nutritional amendments, the introduction of nonindigenous microorganisms, and other bioaugmentation techniques for enhancing biological activity to promote remediation of contaminated sites. Included are laboratory and field studies of the biological processes connected with in situ ...
This timely reference presents the state of the art of the emerging and rapidly changing field of bioremediation of chlorinated solvents, PCBs, and other chlorinated compounds, as well as PAHs, both in situ and on site.

Encyclopedic in scope, this new book presents state-of-the-art methods and techniques demonstrating new applications for biotechnology to remediate contaminated sites. Researchers and practitioners world-wide share their collective evidence to demonstrate how biotechnology works, both alone and in combination with other remediation techniques. ...
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 ...
With oil spills occurring worldwide, much media and practical attention has been given in recent years to the rapidly maturing field of hydrocarbon bioremediation, particularly with application to marine spills. Hydrocarbon contamination of soil and groundwater, although less visible, is even more widespread and has provided the background for the ...
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 ...
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 ...
Metals and their salts typically inhibit rather than support biological processes, but some promising technologies have been developed for bioremediation of inorganic contamination. These articles deal with bench-and field-scale studies of the bioremediation of metals-contaminated soils, sludges, and aqueous environments. In situ and ex situ ...
This volume focuses on biodegradation of xenobiotic compounds in soil and aqueous environments. Articles discuss the bioremediation of media contaminated with PAHs, PCBs, PCP, pesticides, explosives, bis(2)-ethyl-hexyl-phthalate, pharmaceutical residues, and alkylpyridines. Also covered is the variation of nutrient supplies for optimizing ...
An international group of researchers and engineers discuss using natural attenuation to degrade contaminants and thereby remediate soils and groundwater. This volume describes laboratory studies and field demonstrations in support of subsurface remediation at military, manufactured gas plant, landfill, petroleum spill, and other sites. The ...
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 ...
