Cornell Dubilier Electronics

South Plainfield, New Jersey

Site Description

During its years of operation at the site (1936 to 1962), Cornell Dubilier
Electronics, Inc. manufactured electronic parts and components, including
capacitors. It is reported that transformer oils were tested for an unknown period
of time during plant operations. During their operations, Cornell Dubilier
Electronics, Inc. likely dumped polychlorinated biphenyl (PCB) contaminated
materials and other hazardous substances directly onto site soils. The site is
currently known as Hamilton Industrial Park and is occupied by an estimated 15
commercial businesses. Through the years, numerous companies have
operated at the site as tenants. An investigation conducted by the New Jersey
Department of Environmental Protection in the vicinity of Hamilton Boulevard
during the period of 1988-1991 revealed significant ground water contamination
consisting of mainly trichloroethene and tetrachloroethene. Due to widespread
contamination, all residential wells in the area were reportedly closed and
residences were hooked up to a water main providing potable water from
another location.

Current Site Status and Cleanup Actions to Date

•	In 1997, the property owner implemented an interim cleanup to limit
access to the areas of known PCB contamination, limit the surface
water run-off of contaminants to Bound Brook, and pave the parking
surfaces and driveways.

•	In 1998, EPA cleaned the interiors of nearby homes contaminated with
PCB dust from the site.

•	A subsequent action cleaned up the contaminated soil around 18
nearby residential properties.

•	The Remedial Design for building demolition and soil remediation at the
industrial park is currently underway.

•	EPA is currently studying the full nature and extent of ground water and
sediment contamination at Bound Brook.

Current Funding Status

•	To date, EPA has obligated approximately $6.6 million for the site.

•	In September 2006, EPA allocated an additional $5.8 million to the site
for new construction work associated with on-site building demolition.

Key

Accomplishments

•	EPA and the PRPs
have removed
approximately 1,997
cubic yards of
contaminated soil from
residential properties.

•	Eighteen residential
properties have been
remediated.
