LNAPL IN FINE GRAINED SOIL:
Convention, Misconceptions and New Advances
LNAPL recovery systems are proven to be grossly inefficient at recoverying LNAPL in fine grained soil conditions. Many believe this inefficiency is a result of current recovery methods having already reached technical impractibility. To better define technical practictibility and reasonable endpoints for LNAPL sites in fine grained soil, we can better understand the occurrence, saturation, distribution and recoverability of LNAPL in fine grained soil.
This 90-minute webinar will provide practitioners with an advanced understanding LNAPL occurrence and distribution in fine-grained soils and a discussion of the geochemical conditions that affect LNAPL saturations. Comprehensive analysis of various sites will illustrate practical ways to consider LNAPL saturations their residual effects.
HIGHLIGHTS AND OBJECTIVES:
- Why LNAPL does not float on the water table in FGS - or most soil
- Understanding how FGS structure controls LNAPL distribution
- How this distribution can be drastically different than we expect
- Understanding LNAPL saturations measured at field sites
- The impact this has on LNAPL volume
- Understanding residual LNAPL saturation
- Importance of vertical hydraulic gradients in LNAPL distribution
- An introduction to confined LNAPL conditions

Instructor Bio
Mark R. Adamski, PG is a Technical Specialist with BP America where he directs BP and API research in the occurrence and behaviour of LNAPL in the subsurface. He has conducted research on this topic for ten years within BP and conducted, analyzed, and modeled LNAPL distribution and recovery at BP sites worldwide. As a result of this experience he has presented at conferences, seminars, and workshops internationally for several years, including the Midwest GeoSciences Group. He has been involved with the development of landmark regulatory LNAPL guidance documents developed by the State of Texas, ITRC, and the US EPA. His primary areas of current LNAPL study are site characterization techniques, LNAPL metrics, plume migration, and recovery techniques. Mark has worked in modeling fluid migration in porous media throughout his 17 year career with BP. He holds a BS in Geological Engineering and a MS in Hydrogeology. Mark is currently located in the BP office at Westlake in Houston, Texas.
Andrew Kirkman, PE
Mr. Kirkman has 11 years experience conducting environmental investigations and engineering. Mr. Kirkman specializes in subsurface petroleum hydrocarbon, coal tar and creosote distribution, release and recovery studies. He has characterized the distribution and mobility of NAPL at multiple refinery, railroad, retail, manufactured gas plant, wood treating and terminal sites. Mr. Kirkman has worked with regulatory agencies across the nation to accept alternative metrics to NAPL remediation such as NAPL transmissivity or recoverability rather than gauged NAPL thickness alone. Mr. Kirkman has presented technical discussions regarding the use of NAPL transmissivity, petroleum baildown tests, core analyses and laser induced fluorescence technology at multiple conferences. He eagerly promotes the discussion of improved LNAPL understanding through LNAPL forums such as the Interstate Regulatory Council publications and as the chair of an ASTM task group under E50.04 to develop a guidance document on the calculation of LNAPL Transmissivity.
