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 commercial 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.

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.

The Lawrence Aviation received American Resource and Recovery Act (ARRA) funding in fiscal year 2009. The $4.7 million in ARRA funding for this site was used to initiate the LAI property ground water remedy for the site, which consists of a groundwater extraction and treatment system and the in-situ chemical oxidation process. The groundwater extraction and treatment system on the LAI property is currently operating and is expected to stop any further migration of groundwater contamination from the Lawrence property.  A second groundwater treatment system constructed  at the Caroline Avenue Ball Field is also operating and is expected to capture and treat contaminants in groundwater that have left the Lawrence Aviation property in the past.  Currently, EPA is conducting the first five-year review and its purpose is to ensure that the implemented remedies at this site function as intended and continue to be protective of human health and the environment.  It is anticipated that the five-year review will be completed by June 2015.
