Dense, non-aqueous phase liquids (DNAPLs), which are typically chlorinated organic compounds, are one of the most widespread and high-risk types of subsurface contamination. Understanding the subsurface behavior of DNAPLs is technically challenging and methods for site characterization have evolved. The goal of this project was to summarize emerging DNAPL site characterization methods, their applicability in various geological settings, and where they fit into current regulatory processes. This project produced a Web-based guidance document and Internet-based training course, also available on Clu-In, that will help environmental regulators, project managers, and stakeholders improve their understanding of these techniques, prior to major site characterization decisions.
