Use of Permeability Enhancement Technology for Enhanced In Situ Remediation of Low-permeability Media
Abstract
Remediation of contaminants in low-permeability lithologies (hydraulic conductivities of approximately 10^5 centimeters per second [cm/s] or lower) is a significant challenge for many sites, with conventional technologies often failing. Environmental Permeability Enhancement Technology (PET), also known as environmental soil fracturing, is a technology that has shown promise for emplacement of solid (U.S. patent number 7,179,381) or liquid phase amendments into low-permeability lithologies (silts, clays, and some bedrock formations), where standard approaches such as permeation injections (conventional injections into existing pore space) typically fail. This document has been developed under the Environmental Security Technology Certification Program (ESTCP) and is associated with project ER-201430, A Rigorous Demonstration of Permeability Enhancement Technology for In Situ Remediation of Low-permeability Media. The purpose is to: 1) demonstrate appropriate uses of PET for various contaminants and lithology; 2) provide guidance on design, implementation, and monitoring of the technology once it has been selected for use; and 3) provide details necessary for procurement of an effective technology implementation.
