Strandley Manning - Netting Junk

A Superfund site on south Puget Sound in Washington State, contaminated with PCBs and dioxins, has turned out to be a cleanup and restoration success thanks to the early cooperation of NOAA, EPA, and Seattle City Light. Until 1983, the Strandley-Manning Superfund site was used for scrapping and salvaging electrical transformers, with metals recovered by burning the transformer cores. As a result, soil and sediment throughout the site were contaminated with PCB compounds, and some areas contained elevated concentrations of dioxins produced by the burning of PCBs.

Surface runoff and shallow groundwater from the site discharge to an on-site, spring-fed stream that flows into Burley Lagoon through shallow tidal creeks that meander through a saltmarsh. The Lagoon is habitat for a variety of estuarine fish and serves as a migration corridor for steelhead, salmon, and sea-run cutthroat trout.
