During the fall of 2008, the Navy conducted a large field-scale groundwater treatability study at the Hunters Point Shipyard, San Francisco, California. The project evaluated and documented the technical cost and performance involved in using microscale zero-valent iron (ZVI) to remediate groundwater affected by chlorinated compounds, including TCE and chloroform. This innovative project is one of the first documented field studies targeting chloroform with ZVI. The work was performed within a very tight schedule and allowed an unprecedented comparison of injection methodologies and types of ZVI powders. [EDITORIAL NOTE: The Record of Decision for Parcel C, Hunters Point Shipyard, was issued September 30, 2010. It states: "The selected remedy for groundwater consists of actively treating VOCs in groundwater using ZVI or an injected biological substrate to destroy the VOCs in the groundwater plumes at RU-C1, RU-C2, RU-C4, and RU-C5. ZVI would be used to target hotspot areas where concentrations of PCE exceed 15 µg/L and of TCE exceed 110 µg/L."]
