Abstract: The presence of light non-aqueous phase liquids (LNAPL) in the subsurface poses potential environmental liabilities due to risks associated with human health and/or the environment. In addition, the presence of LNAPL may present concerns relating to current or future land use (including property redevelopment) independent of risk. LNAPL (mainly free-phase petroleum hydrocarbons) is a pervasive environmental issue that is technically challenging to identify, quantify and deal with.
This presentation will provide an overview of the understanding of basic LNAPL concepts, site characterization tools, and remedial options. The use of the American Petroleum Institute (API) Interactive LNAPL Guide software will also be discussed (with several model runs) in terms of evaluating LNAPL mobility and recoverability. Case studies and examples of projects performed by CRA will be presented.
Learning Objectives: After this seminar, participants will be able to:
- Recall where to access key information about LNAPL basics, and CRA related LNAPL presentations and research;
- Recognize when to use the API Interactive LNAPL Guide calculation tools;
- Explain why it is important to have a copy of the API Interactive LNAPL Guide software; and
- Demonstrate how to perform select API model simulations.
