What did the Ministry of the Environment find on completing the Pottersburg Creek and Walker Drain 2008 PCB Sampling Study?
The sampling results show that small amounts of PCBs are still present in Walker Drain, Pottersburg Creek and the Thames River. The levels in water and sediment are within or below the levels the ministry considers acceptable for human health. Levels of some ecological standards are exceeded but remain low enough that they are not a significant risk to the environment. Levels continue to decline in fish, clams and water. Levels in sediment are relatively unchanged from the post-cleanup period. Consumption advisories apply for Thames River carp downstream of Pottersburg Creek. Additional sampling is being done in Walker Drain, where the study found PCB levels are moderately higher than in Pottersburg Creek.
