Chromium Ore Processing Residue
It is suspected that "clean granular inorganic fill material" was used as a euphemism for "chromite ore processing residual." The Baltimore Chrome Works plant operated from the 1800s until 1986 at the site in Fells Point. Until 1954, Mutual Chemical Company and its predecessors operated the plant. In 1954 the plant was acquired by
