LNAPL CONCEPTUAL SITE MODELS – GARY BECKETT (October 2017)
LNAPL scientist and industry expert G. D. Beckett, of Aqui‐Ver, Inc., held a half-day workshop on LNAPL (Light‐Non‐Aqueous Phase Liquid) Conceptual Site Models (LCSMs) at the HEER Office on October 11, 2017. A pdf copy of the workshop presentations is posted below.
LCSMs are the foundation for site assessment and site remediation decisions; therefore, a useful and detailed LCSM using easily available standard data or more advanced data collection for complex sites is key. Topics discussed included LNAPL distribution in the subsurface, factors that drive LNAPL distribution, and guidance on characterization and remediation. The workshop included theoretical aspects of LNAPL fate and transport in the subsurface as well as numerous field examples and practical guidance for implementation.
