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 "on-property" ground water remedy for the site, which consists of an extraction and treatment system and the in-situ chemical oxidation process. These actions, aimed at source control, will prevent the further migration of ground water contaminants beyond the LAI plant site boundary. Mobilization for the initiation of field activities occurred in November 2009 and construction was completed in September 2010. The treatment system operation at the LAI Facility began on September 28, 2010, following completion of the Initial Testing Program (ITP). The ITP was the last component of construction related activities and served as the final testing of the entire treatment system. Following the ITP, normal Operation and Maintenance (O&M) were initiated. Construction of the second treatment system down gradient at the Old Mill Pond began in November 2010. Completion is expected by late summer 2011, conditions permitting.
