Dense Non-Aqueous Liquid (DNAPL) contamination at sites continues to be one of the most challenging problems in environmental characterization and remediation. The relatively small size (but large impact) and often heterogeneous distribution of NAPL confounds characterization efforts and frustrates cleanup attempts. In this workshop we offer information on tools and methods that will help improve DNAPL characterization. The DNAPL Basics section will provide the basic physics and chemistry of DNAPL in the subsurface primarily in the context of equilibrium conditions. Along with an understanding of the initial release of the contaminant, an important factor for characterizing and remediating a DNAPL site is an understanding of the ambient material properties and configuration. More often than not, geology is the key. Establishing end case perspectives on DNAPL deposition and distribution with respect to the site’s geologic materials and configuration will inform a site conceptual model and allow better choices for selecting the next step in characterization or remediation.
