On this day May 17, 1983, the United States Department of Energy confirmed that Oak Ridge, Tennessee had the highest levels of mercury pollution ever recorded in water anywhere in the world. The contamination was traced back to operations at the Y-12 National Security Complex, which began during World War II as part of the top secret Manhattan Project.
The Y-12 facility was used to enrich uranium for the development of nuclear weapons, and large amounts of mercury were used in the process of lithium isotope separation. Over the years, improper disposal methods and leaks led to thousands of pounds of mercury being released into nearby creeks and waterways, including East Fork Poplar Creek.
The 1983 report shocked the public and led to a series of environmental investigations, lawsuits and cleanup efforts that would take decades. Oak Ridge became a central case in discussions about Cold War era environmental damage and the long term consequences of unchecked industrial activity during wartime.
Fun fact: It is estimated that over two million pounds of mercury were used at the Y-12 site between 1950 and 1963, with a large portion unaccounted for in official records.
