Project 4: Design Principles and Field-Deployable Models for Economical Remediation of Dioxin-Contaminated Sites

Design Principles and Field-Deployable Models for Economical Remediation of Dioxin-Contaminated Sites: The aims of this project are: 1) Quantify the parameters for integrative remediation of PCDD/Fs in the presence of exogenous B12, hydrogen release compound (HRC), Dehalococcoides mccartyi, and activated carbon (AC), 2) Identify native OHRB and rdhs-mediated pathways for dechlorination and detoxification of PCDD/Fs at TR/SR/PR Superfund sites, 3) Determine the effect of activated carbon (AC) and bioaugmentation on native PCDD/F-dechlorinating OHRB, dechlorination pathways, and rates in microcosms, and 4) Develop and validate site-specific integrative remediation models for PCDD/Fs involving biotic and abiotic interventions.
