| Description | The Department of Ecology investigated sources of PCBs and dieldrin within the Burnt Bridge Creek drainage from December 2013 to October 2014. Fall PCB concentrations in water were moderate, showing no exceedance of the National Toxics Rule (NTR) criterion. Spring PCB concentrations from Cold Creek and Peterson Channel did exceed the NTR. Dieldrin concentrations in water were high in both fall and spring, exceeding the NTR at all Burnt Bridge Creek sites and at Burton Channel. Concentration patterns suggested a continual source. PCB concentrations in sediment were moderate. The highest levels were found in the downstream wetland and the two sites on Peterson Channel. Recommendations include an additional water quality study and a survey of chemicals being applied near the stream. |
