Field Demonstration, Optimization, and Rigorous Validation of Peroxygen-Based ISCO for the Remediation of Contaminated Groundwater - CHP Stabilization Protocol

Abstract

Catalyzed H2O2 propagations (CHP) is the in situ chemical oxidation (ISCO) process with the most robust chemistry and potential for contaminant destruction. However, hydrogen peroxide is unstable in the subsurface and as a result, CHP use has decreased in favor of activated persulfate as an ISCO reagent. Recent advances have been made in stabilizing hydrogen peroxide in the presence of subsurface solids. The addition of sodium citrate, sodium malonate, and sodium phytate can potentially slow hydrogen peroxide decomposition rates by up to 50 fold. The optimal implementation of these stabilizers for use in CHP field applications is detailed in this guidance document.
