Lawrence Aviation Industries, Inc., (LAI) Superfund site is located in the Village of Port Jefferson Station, Town of Brookhaven, Suffolk County, New York. The site is surrounded by residential areas and a few commmercial properties.

Founded at its present location in 1959, LAI was a manufacturer of titanium sheeting for the aeronautics industry. Past disposal practices and the presence of leaking drums at LAI resulted in numerous violations cited by both the Suffolk County Department of Health Services and the New York State Department of Environmental Conservation. In 1980 and 1981, the Department of Health Services required LAI to remove a number of drums of waste materials from the site. The drums contained the chemicals trichloroethylene and tetrachloroethylene, as well as acids (hydroflouric acid and nitric acid), waste sludges containing acid, salt wastes, hydraulic oils and other plant wastes. They conducted a second removal in 1997.

In 1987 the state requested that EPA perform an emergency cleanup in Port Jefferson. EPA has completed the field data collection phase of the Remedial Investigation/ Feasibility Study (RI/FS) at the Lawrence Aviation Industries Site. A significant number of samples of groundwater, surface waters, soils and sediments have been collected and analyzed to assess the extent of contamination. The purpose of the RI is to collect sufficient data to evaluate the nature and extent of contamination at the site. The goal of the FS is to evaluate possible cleanup actions for the site. The soil gas testing to be conducted will provide additional data for the RI.

In addition to the ongoing RI/FS, between September 2004 and April 2005, EPA conducted a cleanup action at the industrial portion of the site. This activity included the disposal of hundreds of drums of hazardous materials, the emptying and disposal of the contents of chemical storage vats, and the stabilization of other waste materials.
