During the 1940s the Manhattan project used a warehouse at this site to house 1200 tons of radium ore that had been mined in the Congo by the Belgium company Union Minière du Haut Katanga. This was shipped to Port Hope, Canada for refinement. The uranium concetrates were shipped back to this wareshouse for short term storage. Approximately 219,000 pounds of orange and yellow sodium uranate were delivered to the site in 1942, and in the following year, approximately 86,000 pounds of the same substance along with 22,000 pounds of sodium uranyl carbonate and 20,000 pounds of black uranium oxide were delivered. The uranium was later distributed to other U.S. government facilities.

In 1989, DOE conducted a radiological survey of the New York Site. The survey identified sufficient contamination and the site was recommended for remediation. In 1991, remedial action of was taken which generated a total of 12 drums of radioactively contaminated waste. These drums were shipped to Hanford for disposal. In 1993 more remedial action was taken which yielded 38 drums of contaminated materials. These were shipped to Clive, Utah, for disposal.
