The accumulation of light non-aqueous phase liquids (LNAPL) such as gasoline, diesel, fuel oil and lubricating oil resulting from historical or catastrophic releases, is present at numerous industrial and hazardous waste sites. Initiating LNAPL removal is the first step in remediating impacted groundwater with the LNAPL recovery process having a profound effect on the ability to cost effectively achieve site closure. In many cases, LNAPL recovery precedes full-scale groundwater design activities or even final site characterization due to regulatory compliance issues. Therefore, the timely and effective implementation of a LNAPL recovery system can result in reduced project costs by mitigating further plume migration, achieving maximum volume of recoverable hydrocarbons, eliminating the source area associated with dissolved phase contamination, and allowing comprehensive groundwater remediation to be employed sooner. Effective LNAPL recovery systems begin with evaluating a number of site-specific parameters to quantify the physical characteristics of the type of LNAPL to be recovered, the hydrogeological environment, LNAPL, plume geometry, and the specified client or regulatory cleanup goals. These parameters are discussed along with their significance in developing a conceptual understanding of the site.
