| Suitable for | |
Contaminated
soil and groundwater matrices containing volatile, semi-volatile and
non-volatile organic compounds, particularly organic hydrocarbon compounds
such as fuel oil or waste oil and PAHs. |
|
| Technique | |
Injection
of oxygen and/or other nutrients to enhance the growth of indigenous
microorganisms to undertake the biodegradation of contaminants in
soil and groundwater. Can also be achieved using controlled extraction of soil vapours inducing recharge of clean air into treatment zone. Ex-situ above ground treatment provides an enhanced environment to encourage microorganisms to degrade volatile, semi-volatile and non-volatile contaminants from the soil matrix. |
|
| Benefits | |
In
situ technology minimises site disruption. Can be performed under existing buildings and structures. Can be used ex-situ to treat large quantities of contaminated material giving appropriate economies of scale. Often requires no additional vapour treatment, thus reducing overall costs. |
