What was the Raleigh four-area remediation project?

IET completed a comprehensive four-area enhanced reductive remediation program in Raleigh, North Carolina, treating 31 injection points across four distinct zones with customized substrate formulations for each area's contaminant profile.

What technology was used at the Raleigh site?

Enhanced reductive dechlorination (ERD) with customized electron-donor substrate formulations was applied across the four treatment areas to stimulate anaerobic biodegradation of chlorinated solvents.

What contaminants were treated?

The program targeted chlorinated solvents through enhanced reductive remediation, with substrate formulations customized to site-specific contaminant conditions in each of the four zones.

How many injection points were installed?

IET installed 31 injection points distributed across the four treatment areas, completed in September 2009.

Can IET design multi-area remediation programs?

Yes. IET routinely designs multi-area, multi-depth remediation programs with area-specific substrate and reagent dosing, as demonstrated by the Raleigh four-area project.
