Electrokinetic (EK) Enhanced In Situ Remediation

Impact/Purpose:
The purpose of the EK Enhanced Remediation Engineering Issue Paper was to provide contaminated site managers further understanding on the potential use and limitations of this technology at their sites. This EIP was developed after a number of EPA employees, both remedial project managers and on-scene coordinators, requested information from ORD's Technical Support Coordination Division for use at their sites. We expect this document will allow both technical staff and non-technical staff to understand the potential use of this technology.
Description:
The U.S. Environmental Protection Agency (EPA) Engineering Issue Papers (EIPs) are a series of technology transfer documents that summarize the latest information on selected waste treatment and site remediation technologies and related issues and present it in a conveniently accessible manner to the user community. EIPs are designed to help remedial project managers (RPMs), on-scene coordinators (OSCs), contractors, and other practitioners understand the type of data and site characteristics that are needed to evaluate a technology for a specific site, as well as ways to design and optimize a technology for a particular application. This EIP summarizes the current knowledge on electrokinetic (EK) enhanced in situ remediation technologies that are deployed for the purpose of removing contaminants in low-permeability (low-k) media. As a technical support document, it describes EK-enhanced remediation with a focus on remedial scoping needs based on direct experience with the development and deployment of the technology in the field. This EIP summarizes relevant information from peer-reviewed literature, government reports, and gray literature (e.g., websites, conference proceedings) and provides references for more in-depth information.
