Description :

This comprehensive technology survey describes and compares the many biological, chemical, and physical processes available for remediating soils contaminated by jet fuels, gasoline, bunker oil, hydraulic and lubricating oils, and related petroleum products. Many details have been collected from the literature and assembled under one cover to provide a convenient and informative reference source for those who must contend with the critical worldwide problem of environmental contamination by these compounds.
The survey was initially conducted for the naval civil engineering laboratory (NCEL), port Huen-eme, CA, which is now merged with other commands in the new naval facilities engineering service center (NFESC). The survey was performed in connection with the installation restoration effort at twenty-nine palms, a marine corps base training and staging facility at twenty-nine palms, CA, on purchase order number N62583/88 P 2085. It was later expanded and updated for this publication.
Bioremediation is emerging as an important tool for treating petroleum-contaminated soils, whether used as a stand-alone technology or in combination with othe'f physical or chemical methods. Bioremediation was considered to be the desired primary approach for remediating the contaminated soil at twenty-nine palms, supplemented, as necessary, by other processes. Also, because of heightened world interest in the phenomenon of bioremediation and its appropriation as a viable treatment option, this book presents an in-depth coverage of its application for contaminated soils.
The results of current research are combined with essential background information to cover all aspects of in situ and ex situ bioremediation of petroleum-contaminated soils. This information elaborates on the numerous factors affecting biodegradation of petroleum hydrocarbons and describes how they can be enhanced to optimize bioremediation. The susceptibility of individual petroleum components to biodegradation by specific microorganisms is reported, as are the chemical reactions and metabolic pathways involved. All groups of microorganisms are considered for their potential contribution, and the effects of both aerobic and anaerobic conditions are discussed.
