Soil Vapour Extraction (SVE) is an in-situ remediation technology where a vacuum is applied to the soil through trenches or boreholes. This induces a flow of air through the unsaturated zone of the soils to remove volatile and some semi-volatile contaminants. The extracted air can be treated to recover or remove any contaminants contained.
Soil Vapour Extraction remediation systems are commonly combined with other remediation techniques such as air sparging.
SVE can remediate a wide range of contaminants including but not limited to:
- Petroleum range hydrocarbons (PRO)
- Diesel range hydrocarbons (DRO)
- Vinyl chloride
- Trichloroethene
- Benzene
- Toluene
- Ethylbenzene
- Xylene
- Most volatiles
- Pesticides and herbicides
Generally a contaminant with a vapour pressure of greater than 1.0mm Hg at 20°c and a Henry’s Law constant greater than 0.0001stm/m3/mol will be suitable for Soil Vapour Extraction.
JS Remediation have decades of experience in Soil Vapour Extraction having worked on Soil Vapour Extraction projects in Ireland, the UK and Africa. JS Remidiation has an extremely impressive client base, including multinationals, blue chips, leading building and mining companies, prominent engineering and environmental consultants, local authorities, utilities, semi-states and other government departments.
At JS Remediation, we pride ourselves on our problem-solving abilities. Our in-house design team develops focused remedial strategies which we can take through from conceptual design and regulator negotiation to full scale implementation, final validation, regulatory approval, and every stage in-between.
