At the U.S. Department of Energy’s (DOE’s) Hanford Site, located in southeastern Washington State, ¹²⁹I was produced as a byproduct of nuclear fission in the site’s nine Pu production reactors. Currently, there are large dilute ¹²⁹I groundwater plumes at Hanford, including a groundwater plume in the 200-UP-1 operable unit (OU) located within the Central Plateau. The interim Record of Decision (ROD) for the 200-UP-1 OU requires that DOE evaluate potential treatment options for I-129 before a final ROD is issued. A remedy evaluation plan was subsequently published and identified the approach for this effort. The laboratory evaluation reported herein is part of the remedy evaluation. This report builds from information gathered in previous literature reviews of potential remedy technologies and provides laboratory testing results for promising candidates in support of determining which candidates warrant additional evaluation through treatability testing.
