PCBs (polychlorinated biphenyls) have been challenging to clean up in Puget Sound and connected rivers due to their chemical stability and persistence in the environment, which allows them to remain in sediment and bioaccumulate in the food chain. Additionally, ongoing sources of contamination, such as stormwater runoff and legacy pollution from industrial activities, complicate remediation efforts. The complex ecosystems and varying sediment types also hinder effective cleanup strategies, making it difficult to fully eliminate these harmful compounds from the environment.
