Hide details for Threats and ContaminantsThreats and Contaminants

Media Affected: Surface Water, Soil & Sludges, Groundwater
Investigations at this site found heavy metals, including lead and arsenic, in the soil in the vicinity of an old auto repair shop and next to the old seaplane nose hanger/repair shop. There were also three soil "hot spots" of pesticide contamination near Building 25 and an area of polycyclic aromatic hydrocarbons (PAHs). All contaminated soil was removed allowing unlimited use of the Seaplane Base. The groundwater and surface water may have been contaminated with heavy metals; however, the groundwater is not potable. The sediments may contain heavy metals and PAHs, but there are no contaminant levels in the bioactive zone of the sediment that affect the flora and fauna. Multiple leaks and spills from fuel and oil tank storage areas may have affected the surface waters of Oak and Crescent Harbors. There was the potential for long-term exposure to the contaminated soil to result in adverse health effects.


Hide details for Cleanup ProgressCleanup Progress

In 1993, the Navy completed an investigation into the nature and extent of contamination at the landfill area, auto repair and paint shop, a disposal area, a nose Hangar, and a salvage yard. The cleanup remedy, selected in 1993, was to excavate the areas of contamination and dispose of the soils in an appropriate off-site landfill. Excavation began in the Summer of 1994, and was completed in early 1995. These actions resulted in the site being available for unrestricted use.

The site was deleted from the NPL on September 21, 1995.
