The purpose of this study is to confirm the ability to inject groundwater directly into a Permeable Reactive Barrier (PRB) and achieve a significant reduction of chlorinated volatile organic compounds (CVOCs) as a result of zero-valent iron (ZVI) assisted reductive dechlorination. Theil-Sen estimation and Mann Kendall testing reveals that directly injecting impacted groundwater to zero-valent iron available to facilitate reductive dechlorination can reduce existing CVOC levels by nearly 70%. Analytical results suggest that trichloroethene (TCE) and cis-1, 2 dichloroethene (cDCE) levels decrease over a remediation testing period. The use of denatured alcohol well treatment mitigated permeability loss throughout the injection to process to ensure viability of the proposed injection methods and subsequent remediation.
