The LI Tungsten Superfund Site is located in the City of Glen Cove, Nassau County, New York. The Site consists of the former Li Tungsten facility property located at 63 Herbhill Road, certain portions of the nearby Captain’s Cove property that were contaminated with radioactive material, and other areas where radiologically contaminated materials associated with the former Li Tungsten facility came to be located, including portions of Glen Cove Creek. 

The former Li Tungsten facility is 26 acres and consists of three separate parcels. The 23-acre Captain’s Cove property is bounded by Hempstead Harbor to the west, Garvies Point Preserve to the north, the Glen Cove Anglers’ Club to the east, and Glen Cove Creek to the south. A four-acre wetland makes up a portion of the Captain’s Cove property’s southern boundary with the Creek.

The Wah Chang Smelting and Refining Company owned the former Li Tungsten facility from the 1940s to about 1984 and, during that period, a succession of entities, including Teledyne Inc. and the Li Tungsten Corp., operated the facility. Operations generally involved the processing of ore and scrap tungsten concentrates to metal tungsten powder and tungsten carbide powder, although other specialty metal products were also produced. Portions of the Captain’s Cove property were used as a dumpsite for a variety of wastes, including the disposal of spent ore residuals by the operators of the former Li Tungsten facility. The Glen Cove Development Corporation (GCDC) acquired the Li Tungsten facility property in 1984 and leased it to the Li Tungsten Corporation, which declared bankruptcy in 1985 and ceased operations.

Glen Cove Creek is a 1.0 mile federal navigation channel that is maintained by the Army Corps of Engineers.  It extends from Hempstead Harbor easterly to the head of navigation at Charles Street near the municipal center of Glen Cove. During routine maintenance dredging in 2001, the Corps discovered the presence of radioactive materials in Glen Cove Creek, which led to the indefinite suspension of the dredging program and the inclusion of the creek as part of the Li Tungsten Superfund Site.
