For some reason DOE refers to the remains left by the Manhattan Engineer District as "legacies," and the long campaign of finding and clearing up the mess left behind by tracking all the uranium and thorium that flowed through the vast system the project created as "linking legacies." The website for this is www.legacystory.apps.doe.gov . Electro Met of NY is only one of 25 uranium processors used in the late forties by MED and AEC, and by no means the largest.
For those interested, a great deal of MED and AEC history can be found on the DOE websites, and is easily searchable.
