NAPL Recovery

Because of past industrial practices, non-aqueous phase liquids (NAPLs) are present at many remedial sites. The regulatory community recognizes both the physical limitations associated with removal of NAPL from the subsurface and the potential for long-term groundwater and soil vapor degradation posed by NAPL. As a result, NAPL recovery, to the extent practical, is often required as an interim remedial measure or as part of an integrated final remedy. This fact sheet provides an overview of a number of NAPL projects.
