Evaluating and Applying Site-Specific NAPL Dissolution Rates During Remediation

Abstract

Remediation of nonaqueous phase liquid (NAPL)-impacted sites is difficult and costly. Even with enhancements (e.g., thermal, chemical), mass transfer constraints of NAPL dissolution govern control of sources and the attainment of cleanup goals. To better manage expenditures, the Department of Defense needs a scientifically-based, process-centric method to evaluate source control provided by past NAPL remediation and the potential benefit of future treatment. Current approaches to predict the impact of remediation include (1) screening models, which are simplistic, and (2) numerical transport models, which are complex and costly. The objective of this project was to establish a practical and cost-effective method to assess source control at NAPL sites using site- and technology-specific NAPL dissolution rates in a volume-averaged source zone.
