Project 18, a Formerly Used Defense Site (FUDS), encompasses 379.6 acres located in the north-central portion of the Waikoloa Maneuver Area (WMA). Project 18 east of Mamalahoa Highway was within the “Maneuver Area 2 Non-Firing” portion of WMA, while Project 18 west of Mamalahoa Highway was in proximity to the known distance ranges used for weapons firing training during the World War II era.
The project is in the remedial action phase of the CERCLA process, with 11.2 acres being investigated under this upcoming action. During this phase, contracted field teams will implement the selected remedy detailed in the decision document.
