Workshop SM3.

All you need to know about the characterisation of non-aqueous phase liquid (NAPL) contaminated sites in 4 hours!


Sunday, 8 September 2019

Instructors: Naji Akladiss, Chuck Newell, Dan Bryant, Heather Rectanus, Ryan Wymore


The site characterization training will be presented in a progression that will start with an introduction that provides the objectives of the training.  We will discuss the changes in the DNAPL, LNAPL, and Contaminant Fate and Transport Site Conceptual Models including the controlling roles of geology and the interaction of NAPLs and dissolved phase contaminants with geology; effects of NAPL types and properties and interactions with the subsurface on contaminant fate and transport.  We will introduce the Integrated Site Characterization Approach including the important of high-resolution characterization, goals based characterization objectives, contaminant phases, and the developing ITRC characterization tools table.

Who should attend?

Environmental consultants, site owners, and environmental regulators involved with characterization DNAPL and/or LNAPL sites will benefit from this course.   The course draws heavily from the recent U.S. Interstate Technology and Regulatory Council (ITRC) DNAPL Site Characterization guidance document, but with a short LNAPL-specific section drawn from ITRC LNAPL guidance.
