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.

Strandley Manning - Fish Reintroduction 2

In May 2000 these fish were returned to their native stream to preserve the original genetic stock from the area and to allow them to return to their normal migratory and reproductive cycle. Cooperative monitoring will continue over the next few years to ensure full success of the stream?s restoration to a healthy aquatic system. Sediment concentrations will be monitored for five years to ensure that they remain below target concentrations. The health of the plantings established during revegetation of the site will be monitored for the first three years after planting. The benthic community in the stream will be monitored annually for five years or until it is determined that the community would be able to sustain fish. Stream flow and the structural stability of banks will be monitored for five years. Finally, the suitability of the stream to support fish will be evaluated. Results from these investigations will also help in planning and evaluating future restoration efforts.
