Description Sources of PCBs, dioxin, and chlorinated pesticides to Vancouver Lake were investigated during the winter, spring, and fall of 2010 from Burnt Bridge Creek, the Flushing Channel, and two Lake River sites. Contaminants were highest during the spring and fall. The NTR human health criterion was exceeded (not met) for total PCBs during all three seasons. Many chlorinated pesticides were detected, but only dieldrin from Burnt Bridge Creek exceeded criteria. Overall Burnt Bridge Creek was ranked the most contaminated of the three inputs to the lake. Lake River north, Lake River south, and the Flushing Channel followed in order of most to least contaminated.
