Superfund Site Profile
The Pierson's Creek site is located in an industrial area of Newark, New Jersey. The site consists of Pierson’s Creek, which discharges to Newark Bay, located approximately 1.5 miles downstream of its headwaters, and several sources of contamination to the creek, including the Troy Chemical Corporation facility, The Troy Chemical Corporation facility, which manufactures antimicrobial and antifungal paint additives and related products is located just upstream of Pierson's Creek. Prior to the facility's current operations, which began in 1956, the facility was occupied by other industrial operators since the late 1800s. In addition, there had been other industries along Pierson's Creek, which may have affected the sediments in Pierson's Creek. Mercury compounds were manufactured at the facility from 1957 until 1987. From 1965 to 1976, the mercury wastewater was treated on-site with sulfide precipitation prior to discharge to the creek. In 1976, an on-site wastewater treatment plant was installed that discharges to the Passaic Valley Sewerage Commission Waste Water Treatment Plant.
In addition to the discharge of mercury-contaminated wastewater, there is a history of spills and discharges to the ground surface characterized by puddles of chemicals on the ground; mercury droplets on the ground and in runoff reaching Pierson's Creek.
