Site Description

Johnson Matthey Incorporated is located on Piney Hollow Road in Winslow, New Jersey. The Johnson Matthey site began operations in 1971. The site occupies approximately seven acres. Activities included the production of process catalysts, salts manufacture, extracting metals from ore, incineration of trash paper and warehousing and packaging of various products. In October 1993, operations ceased at the site, triggering New Jersey's Industrial Site Recovery Act (ISRA). The buildings were subsequently demolished. The property is now owned by Piney Hollow Associates, L.L.C.

Potential Threats and Contaminants

There were 13 solid waste management units (SWMUs) identified as part of the operations area of the site. The contaminants of concern in soil and groundwater included lead, cadmium, beryllium, hexavalent chromium and polychlorinated biphenyls, or PCBs.

Cleanup Approach and Progress

Limited soil excavation was conducted at the site. The New Jersey Department of Environmental Protection (NJDEP) determined that no further action was required for all of the above SWMUs, except for SWMU 8 (the East Pond Area). Surface soil samples of chromium at this SWMU indicated levels above NJDEP Residential Criteria, but below Non-Residential Criteria. There were also other areas of the site (not related to SWMUs) where residential, but not non-residential soil standards were exceeded. As a result, a Deed Notice was implemented, limiting the entire site to non-residential re-use.

There is some groundwater contamination at the site in the West Pond Area. A Classification Exception Area (CEA) has been established for this area of contamination to restrict the use of groundwater and Monitored Natural Attenuation has been selected as the final groundwater remedy.
