Nuclear waste has contaminated Cattaraugus Creek and other areas around West Valley, New York. Although almost all of the high-level nuclear waste has been removed, according to the Department of Energy (DOE), nuclear and hazardous wastes are still buried in unlined trenches on two sites at a former privately operated nuclear fuels reprocessing facility alongside Cattaraugus Creek north of the village of West Valley in Cattaraugus County. The DOE's Demonstration Project at the site transferred high-level nuclear waste into glass canisters. Reprocessing of spent fuel rods from military and civilian nuclear power plants between 1966 and 1972 resulted in burial of low-level radioactive waste (LLNW) on and burial of high-level radioactive waste on another there.
