Chlorinated Solvent and DNAPL Remediation addresses remediation of chlorinated solvents and dense nonaqueous phase liquids (DNAPLs) in groundwater and discusses remedial alternatives that are available for subsurface cleanup. Chlorinated Solvent and DNAPL Remediation: Innovative Strategies for Subsurface Cleanup focuses primarily on current technological developments and innovative applications for in situ remediation of chlorinated solvents including DNAPLs in soil and groundwater.
However, this book also provides a general overview of all of the physical, chemical, and biological processes available for in situ remediation of groundwater contaminated with chlorinated solvents and DNAPLs. Chapters discuss surfactant flushing to enhance DNAPL removal; in situ chemical destruction by reduction processes involving zero valent iron or related metals; in situ chemical destruction by advanced oxidation processes; and in situ biological destruction by enhanced anaerobic bioremediation or natural bioattenuation.
This book also emphasizes zero valent iron-based strategies, including reaction geochemistry, permeable reactive barrier longevity, rejuvenation of iron walls, and emplacement technique. One chapter summarizes 10 years of permeable reactive barrier development and application.
The controversial issues related to DNAPL remediation, including the concept that remediation of sites affected by DNAPL could be technically impractical, are reviewed. Another chapter focuses on the evolution of DNAPL remediation practice.
