In Situ Access to Contaminants

enhancing and enabling subsurface remediation


Achieving the desired contact between remedial materials and contaminants requires control of the subsurface forms created by the injection event.  FRx relies upon a sound understanding of physical and geotechnical principles to adapt injection methods for optimal results.

Practically any remediation agent or material is compatible with one or more of our injection technologies.  Furthermore, FRx can deliver granular solids, such as zero valent iron, by the ton into target formations. Click here for more information.

The physical principles exploited by our injection technologies can be applied to any solid media - whether unconsolidated soil or crystalline bedrock.  Geology does not limit our experience.  Click here for more information.
