Superfund Site Profile
The Lincoln Park site is located south of Canon City in Fremont County, Colorado. The site includes the Cotter Corporation's (Cotter's) 2,600-acre uranium mill and areas of mill-associated contamination, including the Lincoln Park community near the mill. Cotter started producing yellowcake at the Canon City mill in August 1958. Yellowcake is the solid form of mixed uranium oxide, which is produced from uranium ore in the uranium milling process. In addition to producing yellowcake, the mill produced vanadium and molybdenum as byproducts. Historical mill operations and disposal practices contaminated soil, groundwater and sediment with hazardous chemicals. Investigation and cleanup activities at the site are ongoing.
