Recent tests for PCB contamination in Little Bayou Creek near the Paducah Gaseous Diffusion Plant indicate improved conditions, but environmental officials continue to advise consumers not to eat fish caught in the creek.
The Kentucky Natural Resources and Environmental Protection Cabinet prepared a draft report on Little Bayou as required by the Federal Clean Water Act. Comments on the draft report can be made to the cabinet through Feb. 9.

The report said Little Bayou is contaminated with PCBs because of spills and discharges from the gaseous diffusion plant. PCBs are used in capacitors and transformers. Advisories against eating fish from the creek have been consistent since 1992.
The report found that levels of PCBs have dropped from almost two parts per million in 1992 to less than one part per million in the most recent study. The goal is to remove all PCBs.
Contamination has been reduced through improvements in environmental management at the gaseous diffusion plant, and through cleanup efforts that began 10 years ago, the report said.
