Short description: This document provides a framework for assessing the presence of dense non-aqueous phase liquid (DNAPL) and delineating the spatial extent of the DNAPL source zone, a priority at many sites due to the increasing use of in situ remediation technologies. The described strategy expands the applicability of the document to include both unconsolidated deposits and fractured bedrock, and encourage an iterative, flexible site investigation approach
