ELECTROKINETIC-ENHANCED (EK-ENHANCED) AMENDMENT DELIVERY FOR REMEDIATION OF LOW PERMEABILITY AND HETEROGENEOUS MATERIALS: ESTCP COST AND PERFORMANCE REPORT
Cox, E., J. Wang, D. Reynolds, D. Gent, and M. Singletary.
ESTCP Project ER-201325, 72 pp, 2018

EK-enhanced amendment delivery for in situ bioremediation (EK-BIO) was demonstrated and validated via enhanced reductive dechlorination of a PCE source area in clay. The EK-enhanced amendment delivery technology entails the establishment of an electric field in the subsurface using a network of electrodes. The electrical current and voltage gradient established across a direct-current electric field provide the driving force to transport remediation amendments, including electron donors, chemical oxidants, and even bacteria, through the subsurface. Results showed that EK could achieve relatively uniform transport in low-permeability materials. https://www.serdp-estcp.org/content/download/47833/455819/file/ER-201325%20Cost%20&%20Performance%20Report.pdf
