Soil and Groundwater Contamination: Nonaqueous Phase Liquids-Principles and Observations

Published by the American Geophysical Union as part of the Water Resources Monograph Series.Nonaqueous phase liquids (NAPLs) are frequently found as soil and groundwater contaminants. Highly toxic even in small volumes, NAPLs can pose a threat to human health and damage surface and subsurface ecosystems.In this book, we clarify the complex phenomena of NAPL migration and offer insight into the behavior of NAPLs at sites undergoing monitoring and remediation. Contents include discussion on:Principles of NAPL behavior in the subsurface, including flow, transfer of components to water and gas phases, and transportMigration and distributionSite characterization and monitoringRemediation methods, including hydraulic removal, pump and treat, and soil vapor extractionFurther discussion on gaps in our understanding of NAPLs at the field scale along with a thorough tutorial approach and supplemental CD, make this book an important guide and resource for practicing engineers and scientists, risk assessment professionals, teachers, and students.Content: Chapter 1 Introduction (pages 1–3): Alex S.
