Expedited Large Scale NAPL Plume Removal Utilizing Mobile Remediation Solutions

Mobile remediation systems can an attractive alternative to achieve expedited large scale NAPL cleanups. Presented is a cost-effective mobile remedial process that successfully eradicated a >2 acre NAPL plume containing as much as 3.5 feet of gasoline in 37 days. The mobile system employed dual-phase/multi-phase extraction combined with surfactants. Significant reductions in dissolved phase concentrations accompanied the removal of NAPL at this site. Nominal greenhouse gases are emitted during this process.
This site, located in Norman, Oklahoma, presented subsurface and above-surface challenges. The mobile system allowed successful circumvention of numerous surface challenges, including several active businesses, an office park, parking lots, a  five lane highway, and a two lane side street all located within the plume footprint.
The mobile system was implemented within 24 hours of contract execution. This mobile remedial approach has been successfully implemented at over 50 sites throughout the United States and provides the additional benefits of real-time remedial process optimization along with nominal greenhouse gas emissions and consumption of natural resources (which are quantified and presented).
