LM OU - Lake Monitoring Operable Unit

The Lake Monitoring Operable Unit consists of the water and sediment within the boundary of Crab Orchard Lake.  A Preliminary Screening Analysis was conducted in 2000-2001 to assess contaminants in the lake to evaluate risk.  As there is a potential risk to some ecological receptors, the USFWS is conducting further evaluation; however, that investigation will be incorporated into other OUs.

The Illinois Department of Natural Resources (IDNR) publishes advisories of fish consumption.  An advisory against the consumption of certain species of fish at Carb Orchard Lake has been in effect since the early 1980s because of elevated levels of PCBs and recently mercury.  PCB levels in fish have decreased since the original advisory.
