Superfund Site: SHIELDALLOY CORP., NEWFIELD BOROUGH, NJ
Superfund Site Profile
The Shieldalloy Metallurgical Corp. (SMC) site is located in Newfield, New Jersey. The 67.5-acre area was the location of a specialty plant where chromium alloy and other products were produced. Past disposal practices, including the release of processed wastewater, caused groundwater contamination. Soil is contaminated with heavy metals. Area residents have been connected to the public water supply. After initial actions to protect human health and the environment, site investigations and cleanup are ongoing.
Radiological contamination in a restricted area on the SMC facility is not part of the Superfund site and is being addressed by New Jersey Department of Environmental Protection (NJDEP), as authorized by the U.S. Nuclear Regulatory Commission (NRC). The restricted area is surrounded by a chain link fence with barbed wire and is posted with specific signage. Inside the perimeter fence is a storage area with slag and dusts containing low levels of radioactive isotopes generated during past facility operations. Further information about the environmental response actions to address the restricted area is available from NJDEP.
