Multi phase vacuum extraction

We have a history of delivering reliable, cost-effective land remediation techniques

Our ability to ensure safe, award-winning land remediation for some of the country's biggest operators has never faltered.

Applying a powerful vacuum to the surface of groundwater, multi phase or dual phase vacuum extraction is a highly flexible treatment system, adept at recovering floating fuel and hydrocarbons from the environment.

Through sustained application, a vacuum gradient is developed that can pull contamination from surrounding soil pores. This ensures maximum recovery with minimal toxic rebound.

Following free phase hydrocarbons removal, the system may be further optimised to treat contaminated groundwater plumes or it can be used in conjunction with a chemical injection programme - further reducing treatment times and maximising recovery.

By utilising a network of trenches on live sites, we can accommodate any operation, no matter how big or small. This, paired with our 20+ years of experience in land remediation, ensures a service that treats hydrocarbons efficiently, irrespective of job size.

Anglesey: Dual Phase Vacuum Extraction and Chemical Oxidation

The issue

Decades of heavy industrial activity on a former aluminium site in Anglesey left a legacy of significant contamination. Diesel leaks from underground tanks, oil spills from industrial compressors and fire damage incidents leading to transformer oil spills left the site in need of immediate attention.

The solution

A detailed investigation and pilot testing enabled the design of an in situ treatment solution. This aimed to address three separate contaminant plumes, covering an area of <0.5 hectares. The team targeted saturated soils and groundwater within the complex geological setting of made ground, superficial gravels and an underlying fractured schist bedrock.

The result

This combination of techniques successfully removed all detectable contaminants and achieved a reduction in dissolved hydrocarbon concentrations, in all areas, of greater than 95%. As a result, regulatory approval of the works was secured and the development potential of the site was unlocked. This work culminated in an award for theGeo² team - an award-winning service, delivered quickly to save the client £100,000s.
