Setting |
- Seymour Johnson AFB, North Carolina
- Two FreeOx™ systems. Active fighter jet flight line.
- Jet fuel contamination in soil and groundwater. Floating product previously removed; only a sheen remains.
|
Hydrogeology |
- Fine sand aquifer:
- Hydraulic conductivity: unknown
- Plume thickness: 3 - 4 ft
- Depth to groundwater: 9 - 11 ft
|
Contamination |
- BTEX up to 2,400 ppb
- C9 - C18 aliphatics up to 640,000 ppb
- C9 - C22 aromatics up to 145,000 ppb
- Primary Objective: Increase dissolved oxygen in groundwater to increase natural attenuation by aerobic degradation.
|
Operation Details |
- Two FreeOx™ systems, each with one extraction and one release well. The two systems operate at 0.5 gpm and 0.2 gpm.
- Oxygenation of groundwater up to saturation with dissolved oxygen for removal of dissolved contaminants through biodegradation.
- System startup scheduled for early summer 2009.
