Density-driven convection wells clean up MTBE-contaminated site

Article Abstract:

The Wilmington, NC, office of the North Carolina Waste Management Division's Underground Storage Tank unit received a site closure report on Aug 1994, that showed that solid and groundwater samples at a former Fast Fare service station exceeded state groundwater quality standards. The agency contacted a company to perform site characterization due to the presence of methyl tertiary butyl esther and other contaminants in the property. The company recommended the use of a remediation system using density-driven convection well technology. The system was installed and its operation began in May 1997. It has, since then, proven to be a highly effective groundwater treatment technology costing up to 50% less than other technologies.
