Stage of Clean-up: Study Underway

Conditions at Proposal (July 29, 1991): The Pearl Harbor Naval Complex occupies at least 6,300 acres in Pearl Harbor on the Island of Oahu, Honolulu County, Hawaii. Land around the complex supports agriculture, aquaculture, industry, urban, and commercial uses. The complex consists of these major facilities: Naval Shipyard, Naval Supply Center, Naval Station, Submarine Base, Public Works Center, Inactive Ships, and Navy Magazine Lualualei (Westlock Branch and Waipio Peninsula). The Pearl Harbor Naval Complex began operation in 1901 when the Navy received an appropriation to acquire land for a naval station. After the attack by the Japanese on December 7, 1941, industrial activity at the complex skyrocketed, reaching 24,000 civilians by mid-1943. After World War II, activity declined and has fluctuated with the Navy's requirements. In 1983, the Navy identified 30 potential hazardous waste sources within the six facilities. Subsequently, an additional source was identified.  More...

Sources of Contamination:

• Discharge to sewer/surface water
• Dumping - unauthorized
• Inadvertent spill
• Incineration residuals handling
• Lagoon disposal
• Lake or river - disposal in
• Landfill
• Ocean disposal
• Recycling (Other than primary operation)
• Storage - drums/containers of waste
• Storage - raw material
• Waste pile
• Waste tank - above ground
• Waste tank - below ground

Soil, groundwater and sediment are contaminated with metals, organic compounds and PETROLEUM HYDROCARBONS. There is a potential human health and ecological risk with contact or accidental ingestion with the contaminated media
