Description:
Dense non-aqueous phase liquid (DNAPL) poses a difficult problem for subsurface remediation because it serves as a continuing source to dissolved phase ground water contamination and is difficult to remove from interstitial pore space or bedrock fractures in the subsurface. Numerous technologies have been developed for DNAPL remediation, but demonstrations of these technologies have had mixed results. This document summarizes the performance and results of DNAPL removal demonstration projects at five sites with the purpose of informing the hydrogeology and remedial engineering community of the results and lessons learned from these demonstrations. Most of the technologies were successful at removing contaminant mass from the subsurface, and project performance varied with the degree of project planning and site conditions. Each of the projects is discussed and evaluated for success relative to the project objectives and within a financial/regulatory framework that is typical of most contaminated sites. Lessons learned and considerations for future applications based on each project are provided along with lessons learned for conducting future demonstration projects
