Soil and Groundwater Contamination – Nonaqueous Phase Liquids: Water Resources Monograph

Published by the American Geophysical Union as part of the Water Resources Monograph Series, Volume 17.

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 transport
• Migration and distribution
• Site characterization and monitoring
• Remediation methods, including hydraulic removal, pump and treat, and soil vapor extraction
• Further 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.
