Description
The former Bristol Socket Screw (BSS) property is located at 4 Pines Bridge Road in Beacon Falls, New Haven County, Connecticut. The 1.3-acre former BSS property is currently occupied by Knapp Container, Inc. A single building and a paved parking area are located on the former BSS property. The former BSS property is bordered by Old Turnpike Road to the north; Route 8 to the east; a residential property to the south; and Route 42 to the west. The BSS property is served by public drinking water and a septic system is located on the property.
Prior to 1973, the former BSS property was owned and operated by the Ideal Manufacturing Company (IMC), which manufactured safety pins, badge pins, and drapery and shower hooks. IMC generated the following types of waste: scrap metals, grinding dust, xylene-soaked waste, waste oil, spent vapor degreaser, and compressor condensate blowdown. BSS occupied the property from 1973 to 1977. BSS manufactured socket screws on the property. BSS used the following processes on the property: “cold heading”, operation of automatic screw machines (which used cutting oil), thread rolling and grinding, vibratory tumbling, and secondary operations (such as drilling and tapping). The wastes generated by BSS included used cutting oil, tetrachloroethylene (PCE), used vapor degreaser, and spent Magnus No. 1073 cleaner/soap degreaser/rust inhibitor (which contained 15% sodium nitrate, 5% triethanolamine, and 3% xylene sulfonate). Knapp Container, Inc. began corrugated and solid fibreboard box manufacturing operations on the former BSS property in 1978.
In a 1982 inspection, Connecticut Department of Environmental Protection (CT DEP) noted that an unknown amount of waste solvent (Magnus No. 1073) was disposed of to the on-site septic system. Reportedly, waste oil and waste PCE generated by BSS were stored in drums at the BSS facility until removal from the property by a licenced waste hauler.
In 1989, CT DEP completed a Preliminary Assessment of the BSS property for the U.S. Environmental Protection Agency (EPA); and in 1994, a contractor to EPA completed a Site Inspection (SI) of the BSS property. Reportedly, an additional investigation, including unspecified sampling, was conducted on the former BSS property by a private contractor in the 1980s, but no evidence of additional investigations was found in available files. Possibly contaminated soil and the on-site septic system are the only source areas identified on the former BSS property. No documented source samples have not been collected from the former BSS property. Review of CT DEP files did not indicate that any additional work has been performed at the former BSS property since the 1994 SI.
The depth to groundwater and beneath the former BSS property is approximately 10 feet below ground surface; the direction of groundwater flow beneath the property is suspected to be westerly, towards the Naugatuck River. The nearest private groundwater supply is located approximately 0.2 miles west of the former BSS property. The nearest public groundwater supply is located approximately 1.5 miles southwest of the former BSS property. An estimated 16,052 people rely on groundwater sources located within 4-radial miles of the former BSS property for drinking water. No nearby drinking water wells have been reported to be impacted; however, no groundwater sampling has been conducted.
Runoff from the former BSS property enters the Naugatuck River, 600 feet west of the former BSS property, via storm drains. The Naugatuck River flows southerly and discharges to the Housatonic River. No surface water intakes are located downstream of the former BSS property. Recreational fisheries are located downstream of the former BSS property. Habitats for State-protected species and approximately 4 miles of wetland frontage occur along the 15-mile downstream surface water pathway. No documented surface water and sediment samples have been collected downstream of the former BSS property in an effort to document a release to surface water.
In 1994, approximately 10 workers were present on the former BSS property. Access to the former BSS property is not restricted by fences and gates. An estimated 1,222 people live within 1-radial mile of the former BSS property. No documented shallow soil samples have been collected on the former BSS property.
An estimated 30,871 people live within 4-radial miles of the former BSS property. Habitats for species with State-protection status and wetlands are located within 4-radial miles of the former BSS property. No complaints of air releases from the former BSS property were found in available files.
