Michael Hawthorne, PG - GEI Consultants, Inc. Mark Adamski - BP America Sanjay Garg, PhD - Shell Global Solutions (US) Inc. Andrew Kirkman, PE - AECOM Have you ever wondered why the apparent NAPL thickness (ANT) gauged in wells at a site is large, but increased groundwater extraction does not increase LNAPL recovery rate? The cause may be perched LNAPL. BACKGROUND: Much like groundwater, LNAPL can be perched on finer-grained soils in the vadose zone, although the underlying processes that cause LNAPL and groundwater to perch...
