AB: In-situ chemical oxidation (ISCO) has gained support as a remediation technique for immiscible-liquid contaminated source zones. 1,1-dichloroethene (DCE) is present at the Samsonite Building Area, which is part of the Tucson International Airport Authority Superfund Site. Based on prior site characterization, DCE is thought to be located in a lower permeability zone adjacent to the water table of a local groundwater zone. A pilot-scale ISCO demonstration project using potassium permanganate (KMnO₄) was conducted at the site. Bench-scale studies using core samples were used to determine natural oxidant demand and establish optimal KMnO₄ injection concentration. Single, sequential, low-pressure injections were implemented for a 9-well network encompassing the primary source zone. Groundwater monitoring was performed before, during, and after injection.
