Superfund record of decision (EPA Region 10): NAS Whidbey Island (operable unit 1, areas 5 and 6), Oak Harbor, WA, December 1993. Final report
The decision document presents the selected final remedial action for Operable Unit (OU) 1, one of four operable units, at the Naval Air Station Whidbey Island, Ault Field, Superfund site near Oak Harbor, Washington. This remedial action addresses the risk to the public posed by volatile organic compounds in leachate and groundwater. The purpose of this action is to reduce the risk associated with the continued spread of the contaminated groundwater plume at Area 6 and remediate the groundwater through two different categories of actions. The second action category is groundwater controls, which are intended to prevent further movement of contaminated groundwater across the site boundary and to prevent consumption by area residents of groundwater exceeding maximum contaminant levels. Major components of the remedy include the following: Capping the Area 6 landfill operations area; Extracting groundwater from the shallow aquifer beneath the western boundary of the Area 6 landfill, treating it by air stripping; Monitoring groundwater; Monitoring off-site water supply wells; Monitoring groundwater in the shallow aquifer at Area 5 for inorganics; Implementing institutional control. The selected remedies are protective of human health and the environment, in compliance with federal and state requirements that are legally applicable or relevant and appropriate to the remedial action, and cost-effective.
