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 the book as a source of information, data and equations to support quantitative assessments of pollutant fate and transport.
Abstract. Introduction. Contaminant Vapors as a Component of Soil Gas in the Unsaturated Zone. Liquid Contaminants Adhering to "Water-Dry" Soil Particles in the Unsaturated Zone. COntaminants Dissolved in the Water Film Surrounding Soil Particles in the Unsaturated Zone. Contaminants Sorbed to "Water-Wet" Soil Particles or Rock Surface (After Migrating Through the Water) in Either the Unsaturated or Saturated Zone. Liquid Contaminants in the Pore Spaces between Soil Particles in the Saturated Zone. Liquid Contaminants in the Pore Spaces between Soil Particles in the Unsaturated Zone. Liquid Contaminants Floating upon the Water Tables. Contaminants Dissolved in Groundwater. Contaminants Sorbed onto Colloidal Particles in Water in Either the Unsaturated or Saturated Zone. Contaminants That Have Diffused Into Mineral Grains or Rocks in Either the Unsaturated or Saturated Zone. Contaminants Sorbed onto or into Soil Microbiota in Either the Saturated or Unsaturated Zone. Contaminants Dissolved in the Mobile Pore Water of the Unsaturated Zone. Liquid Contaminants in Fractured Rock or Karstic Limestone in Either the Unsaturated or Saturated Zone. Glossary.
