Middlesex Sampling Plant Information
Location
Mountain Avenue
Middlesex, New Jersey
In the 1940’s and 1950’s the Middlesex Municipal Landfill was a repository for wastes from the Middlesex Sampling Plant.
In 1980 this site was designated as part of the Formerly Utilized Site Remediation Action Program (FUSRAP), Environmental remediation work took place in 1984 and 1986. This work was performed under the Bechtel In 1943, the Manhattan Engineer District (MED) established the Middlesex Sampling Plant to assay, sample, store, and ship uranium, thorium, and beryllium ores.
Until 1950, the plant was operated by the MED and then the AEC. By 1948, Ledoux and Company and Lucius Pitkin, Inc. personnel were stationed on site to perform assaying work. Another contractor, Perry Warehouse, provided laborers until about 1950.
From 1950 to 1955, United Lead, a subsidiary of National Lead Co., operated the plant for the AEC. The plant discontinued uranium and beryllium assaying and sampling activities in 1955 and was used as a thorium storage and sampling site until 1967. In 1967, operations at Middlesex were terminated and all remaining thorium sampling activities were transferred to the Feed Materials Production Center and to the Weldon Spring Plant.
Approximately one dozen contracting companies and subcontractors were involved in the cleanup effort between 1980-1982. Between April and August 1986, material from the Middlesex Municipal Landfill was entombed at the Middlesex Sampling Plant. No further remediation was performed on-site prior to the responsibility for cleanup being shifted to the Corps of Engineers in 1997.
Throughout the course of its operations, the potential for beryllium exposure existed at this site, due to beryllium use, residual contamination, and decontamination activities.
