Abstract |
The Oak Ridge Reservation (USDOE) (Operable Unit 18) site is located adjacent to the City of Oak Ridge, Anderson County, Tennessee. The Plating Shop Container Areas, which are within the fenced security area of Y-12, receive spent plating solutions and sludge. Spills in the Plating Shop Container Areas have released inorganic and organic contaminants to the surrounding subsurface soil; however, migration of contaminants to ground water and surface water is unlikely because they are present at low concentrations. The ROD addresses OU18, the soil in the Plating Shop Container Areas. Because the Plating Shop Container Areas are within the fenced security of Y-12 and are devoid of vegetation, the probability of detectable impacts to terrestrial and aquatic plants and animals is low. Currently, the total excess cancer risk is below the EPA-established range of concern, and noncarcinogenic health effects are also below the threshold for potential concern, based on a conservative exposure to protect human health at the Y-12 Plating Shop Container Areas. Therefore, there are no contaminants of concern affecting this site. |
