Demonstration of permeability enhancement technology for in situ remediation at three low permeability sites

Effective amendment delivery at low-permeability sites remains one of the most challenging obstacles in the remediation industry. Permeability enhancement technology (i.e., environmental fracturing) has been shown capable of improving amendment delivery and treatment effectiveness at many sites where conventional injection techniques are ineffective. A rigorous demonstration of environmental fracturing for treatment amendment distribution in low permeability media in different geologic settings was performed to provide for the first time the costs and benefits compared to previous conventional injections at the same sites.
