The Hollingsworth Solderless Terminal Company (HSTC) site is located in Fort Lauderdale, Broward County, Florida. The 3.5-acre site was in operation from 1968 until the company closed the facility on October 1, 1982. HSTC manufactured solderless electrical terminals. The manufacturing process included heat treatment in molten salts baths, degreasing, and electroplating. For approximately eight years, HSTC disposed of wash water and process wastewater contaminated with trichloroethylene (TCE), and/or heavy metals into drainfields adjacent to the manufacturing plant. Disposal practices at the site have been clearly documented; however, the amounts of TCE disposed of and the exact locations and duration of disposal remain undocumented. The waste TCE was used both as a degreasing solvent and for cleaning floors, equipment, etc. Primary contaminants at the site include TCE, vinyl chloride, trans-1,2-dichloroethene, and to a lesser extent, nickel, tin, and copper.
