Welcome to the Applied NAPL Science Review
Applied NAPL Science Review (ANSR) is a scientific ejournal that provides insight into the science behind the characterization and remediation of non-aqueous phase liquids (NAPLs) using plain English.
We welcome feedback, suggestions for future topics, questions, and recommended links to NAPL resources. All submittals should be sent to the editor. To receive the quarterly updates, sign up below.

GEI Consultants, Inc. How do you know if the apparent LNAPL thickness gauged in a well is exaggerated? The answer can mean a substantial difference in predicted LNAPL volumes and associated cleanup costs. BACKGROUND: As discussed in the last issue (“LNAPL Thickness Revitalized”), LNAPL thickness is an important LNAPL Conceptual Site Model (LCSM) variable. However, the thickness used in multiphase LNAPL volume calculations must be the formation LNAPL thickness (saturation curve height). Under unconfined conditions, apparent LNAPL thickness gauged in wells is a good approximation of the formation LNAPL thickness (mobile LNAPL interval excluding the smear zone). However,...
