| Suitable for | |
Removal
of dissolved phase volatile and semi-volatile contaminants from groundwater. |
|
| Technique | |
Air
introduced below groundwater causes bubbles to spread out and rise
through the saturated zone. Dissolved phase contaminants are partitioned into vapour phase and migrate to the surface of the groundwater for subsequent collection using a vapour recovery system |
|
| Benefits | |
Increased
supply of oxygen enhances any bioremedial activity. No water extraction and surface treatment required. Unobtrusive low maintenance system with associated lower cost. Low maintenance/low cost remediation option. |
