Between 1950 and 1963, large qantities of elemental (metallic) Mercury were used for Lithium separation at the Y-12 Plant. These past activities have resulted in releases of considerable amounts of Mercury to the environment, to include soil, sediments, surface water, groundwater, and air. Mercury contamination also occurs in the soil and sediment along the floodplain of East Fork Poplar Creek in the City of Oak Ridge and in the Clinch River. Residual Mercury still remains within equipment and in process and effluent drain lines within facilities used for past Mercury activities. Current releases of Mercury from these former Mercury-use buildings account for a significant part of the Mercury leaving the Y-12 Plant. Historical losses during the 1950s and 1960s, however, far exceed the current releaases; e.g., the peak annual release of 70,000 pounds occurred in 1957, while the total releases in 1993 were 16 pounds.
