Each site contaminated with dense nonaqueous phase liquids (DNAPLs) is different and requires a site-specific approach to implementing an effective treatment technology and verifying its performance. The Strategies for Monitoring the Performance of DNAPL Source Zone Remedies (DNAPLs-5, 2004) guidance document provides approaches to performance monitoring while implementing various in situ technologies for the treatment of dense nonaqueous phase liquids. It provides guidelines as to the best way to balance performance objectives against site-specific stratigraphy, measurement uncertainties, regulatory acceptance, and cost.
