L-3 Communications (L-3) occupies one acre of land located at 960 River Road, Bristol Township, Bucks County, Pennsylvania. The facility is a manufacturer of high quality circuit boards for the aerospace, aircraft, and electronic data communication industries, and is a leading provider to the Department of Defense, Department of Homeland Security, selected U.S. government intelligence agencies, and aerospace prime contractors. The facility was owned and operated by Aydin Corporation from 1967 to 1999 at which time it was acquired by L-3, the current owner/operator.

The facility is a small quantity generator (SQG) of hazardous waste that operates in a single one-story building which houses storage, manufacturing, and clerical operations. Approximately 90 percent of the property consists of impermeable surfaces (i.e., the building and paved areas). The remaining ten percent of the property (primarily the northern portion of the property) is grass-covered, the majority of which serves as the facility's storm water detention basin. The facility is situated within a small commercial/industrial area surrounded by residential land uses. The nearest residential area is located approximately 400 feet northeast oftre facility.

Operations performed at the facility include the assembly, cleaning, etching, and plating (copper, nickel, and gold) of custom circuit boards. Wastewater generated in the facility 's laboratory, plating lines, solder strip line, and copper etch area is treated on-site by flocculation and pH adjustment. Treated wastewater is discharged to the Bristol Township wastewater treatment.
