US EPA/ORD's Engineering Issue Paper: Electrokinetic (EK)-Enhanced In situ Remediation Technologies — Options for Addressing Contaminants in Low-Permeability (Low-k) Environments

US EPA's Office of Research and Development (ORD) is sponsoring a presentation on electrokinetic (EK)-enhanced in situ remediation technologies that are available for addressing contaminants in low-permeability (low-k) subsurface environments where conventional hydraulic delivery technologies often face challenges.

The presentation introduces ORD's recently published Engineering Issue Paper (EIP) on the technology. The primary author will present on EK technologies and provide insights to the user community on ways to best utilize the EIP.

ORD's 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 contaminated sites technical staff and site managers 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.
