Non-Aqueous Phase Liquids (NAPLs) in Subsurface Environment: Assessment and Remediation

Proceedings of a specialty conference at the ASCE National Convention, held in Washington, D.C., November 10-14, 1996.

This collection contains 68 papers addressing the contamination of soil and groundwater with nonaqueous phase liquids (NAPLs). A growing number of recent incidents of such contamination has caught the nation unprepared, and challenges confront government agencies, the academic research community, and private industry. The urgency of cleanup necessitates swift progress in several directions: assessment and characterization of NAPL-contaminated sites, assessment and management of the risks involved, development of remediation technologies which are both technically and economically feasible, and development of concepts involved in fate and transport of the NAPLs in their various forms in the subsurface. Although the past decade has seen considerable progress in all these areas, a synthesis of the developments made in various disciplines and the progress achieved is essential to further progress in this important area. Topics include: site assessment and characterization; remediation technologies; analysis and modeling of fate and transport; and case studies of some NAPL sites.
