Evan Cox, M.Sc. (Ontario) will present "Effective Treatment of Chlorinated Solvents in Clay and Silt Using Electrokinetic Techniques" during the Strategic Environmental Research and Development Program (SERDP) and Environmental Security Technology Certification Program (ESTCP) webinar number 80 at 12:00 p.m. EST on October 4, 2018.

Evan is a Senior Principal Remediation Scientist based in Ontario with more than 15 years of experience focused on managing and directing soil and groundwater remediation projects dealing with emerging and recalcitrant contaminants.

SERDP and ESTCP have launched a webinar series to promote the transfer of innovative, cost-effective and sustainable solutions developed through projects funded in five program areas. The webinar series targets Department of Defense (DoD) and Department of Energy (DoE) practitioners, the regulatory community and environmental researchers with the goal of providing cutting edge and practical information that is easily accessible at no cost.

SERDP is DoD's environmental science and technology program, planned and executed in partnership with DoE and U.S. EPA, with participation by numerous other federal and non-federal organizations. SERDP invests across a broad spectrum of basic and applied research, as well as advanced development.

ESTCP is DoD's environmental technology demonstration and validation program. The Program was established in 1995 to promote the transfer of innovative technologies that have successfully established proof of concept to field or production use. ESTCP demonstrations collect cost and performance data to overcome the barriers to employ an innovative technology because of concerns regarding technical or programmatic risk, the so-called "Valley of Death."

Abstract

Contaminants in clays and silts are long-term sources of pollutants to groundwater, requiring costly remediation and monitoring over many decades. Significant advances have been made in the past few years in the area of electrokinetically (EK) enhanced amendment delivery to treat contaminant source areas in low permeability and highly heterogeneous subsurface materials. ; EK is an innovative approach that uses electrokinetic mechanisms to promote the migration of amendments through clays/silts through electromigration, electroosmosis and/or electrophoresis. ; EK approaches are not dependent on hydraulic conductivity and can therefore achieve uniform and rapid distribution of amendments in clays and silts. ; Amendments can include electron donors (e.g., lactate), electron acceptors (e.g., nitrate), and/or microorganisms (e.g., ;Dehalococcoides, ;Dehalobacter) for in situ bioremediation (EK-BIO), or oxidants such as permanganate or thermally-activated persulfate for in situ chemical oxidation (EK-TAP and EK-ISCO, respectively). This presentation will discuss how and where these EK remediation technologies work in addition to providing in-depth results from a recently completed successful ESTCP demonstration/validation project of the EK-BIO technology to treat a tetrachloroethene (PCE) source area in clay at Naval Air Station Jacksonville, Florida (NAS-JAX; ESTCP; ER-201325).
