DNAPL Managements Overview
Abstract
This Dense Non-aqueous Phase Liquid (DNAPL) Management Overview provides an introduction on how to manage DNAPL contamination at a site. Because DNAPL sites can be very challenging, this document focuses heavily on the limitations of characterizing and removing DNAPL, and how to make realistic management decisions in the midst of these uncertainties. Part of the challenge is that no technology has consistently achieved maximum contaminant levels (MCLs) at DNAPL sites; in fact, to date there are no documented, peer-reviewed case studies where MCLs were achieved throughout the DNAPL source zone. Another part of the challenge is that applying source-zone remediation technologies without well-defined project objectives will likely lead to excessive costs, risks, or failures. Two case studies are presented to highlight different approaches to managing sites impacted with DNAPL. The information provided in this Overview is based on Navy Remediation Innovative Technology Seminar (RITS) presentations given in October 2001 and Spring 2006.
