This book identifies the most important 'rules' governing transport, partitioning, retention and transformation of leaked motor fuels in the underground environment. It examines micro-scale fate and transport processes as a means toward promoting a better understanding of larger scale movement of contaminants. Environmental scientists, engineers, consultants, and managers will find "Mobility and Degradation of Organic Contaminants in Subsurface Environments" to be a useful technical handbook. Less experienced users will appreciate its in-depth explanations of the fate and transport processes vital to effective remedial response. More experienced users will use this book as a source of information, data and equations to support quantitative assessments of pollutant fate and transport.
