Injection Technology

In-situ remediation is highly dependent on effective injection technology and saturation of the contaminant plume with remediation product.

Vertical injection pathways are efficiently installed using direct push or auger drilling technology. Remediation product is injected into the strategically placed injection tubes where it disperses downward and outward saturating the area. Injection wells can be installed inside buildings through concrete floors to reach contaminants located under buildings.

Horizontal injection pathways expedites in-situ remediation. Biological and/or chemical amendments can be injected separately or simultaneously ensuring saturation and the destruction of contaminants.

This process has proven highly effective in low permeability soils.

Solid or liquid phase amendments ensure the horizontal injection pathways remain open. These proprietary amendments allow bioremediation or chemical oxidation products to efficiently pass, saturating the contaminant plume. The amendment remains in place keeping the pathway open for multiple injections if necessary.

Former barriers to in-situ remediation such as low permeability soil types (silt and clay), depth and poor accessibility (under structures) have been overcome.
