Michael Hawthorne, PG - GEI Consultants, Inc. Andrew Kirkman, PE - AECOM LNAPL transmissivity incorporates NAPL physical properties, saturation and relative permeability as well as aquifer parameters, and correlates well with LNAPL recoverability. It provides a recoverability metric that is comparable between sites regardless of geology or product type. It is a substantially improved metric over apparent NAPL thickness gauged in wells. BACKGROUND: Apparent NAPL Thickness (ANT) gauged in wells has a long history of...
