Injection Technology

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

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. Such pathways can be installed inside buildings through concrete floors to reach contaminants located under buildings.

Horizontal injection pathways (fractures, performed by Frac Rite Environmental), 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 such as silts and clays. Hydraulic Fracturing creates a network of sand-filled horizontal pathways that are highly permeable. Such fractures can be installed at any depth, through any soil type.

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.

Advanced tiltmeter fracture mapping technology enables us to determine the orientation, extent, thickness and shape of created fractures. It also enables the measurement of amendment distribution throughout the subsurface.

Computer graphics software depicts individual fractures and/or the entire network of fractures as animated illustrations. Confirming the area and direction of fractures ensures coverage throughout the contaminant plume field is achieved.

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