Lawrence Aviation Industries
Port Jefferson Station, New York

Site Description

The Lawrence Aviation Industries (LAI) site is located in Port Jefferson Station, Suffolk County, NY. The 126-acre site includes the LAI facility and several outlying parcels of undeveloped land. The facility has been making titanium sheeting for the aeronautics industry since 1959. Past disposal practices have resulted in a variety of contaminant releases including volatile organic compounds, acid wastes, polychlorinated biphenyls (PCBs), oils, sludge, metals, and other plant wastes. Releases of hazardous substances from the facility have contaminated site soils and ground water, surface water, and down-gradient sediment.

Current Site Status and Cleanup Actions to Date

• In 1987, EPA extended water mains to residences with private wells affected by ground water contamination.
• During 2004 EPA undertook another action to stabilize remaining on-site materials and to reduce the threat of a hazardous substances' release. Approximately 1,300 drums, containers, and cylinders containing various flammable liquids, solids and gases, and unknown compounds were disposed off site.
• EPA selected a comprehensive remedy for the site in 2006, which includes excavation and removal of PCB-contaminated surface soils. The selected remedy for ground water includes extraction and treatment of off-property ground water. In addition, the remedy calls for extraction and treatment and in situ chemical oxidation enhancement of on-property ground water.
• After EPA issued the remedy in 2006, several residences and a school gymnasium were provided with systems to control vapor intrusion.

Current Funding Status

• In Fiscal Year 2008, EPA obligated approximately $2.5 million for cleanup activities at this site to conduct the excavation and removal of PCB-contaminated surface soils and to treat contaminated ground water.
• To date, EPA has obligated a total of nearly $3.5 million for cleanup activities at this site.
