Hylebos Waterway, A Superfund Site and Historical Standup Paddle Adventure in Tacoma, Washington.

The Commencement Bay Nearshore/Tideflats (CB/NT) Superfund site is located in Tacoma, Washington at the southern end of Puget Sound. EPA placed the site on the Superfund National Priorities List in 1983 after discovering widespread contamination.. The Hylebos waterway contains a toxic blanket of sediment contaminated with PCBs, PAHs, arsenic, hexachlorobenzene, hexachlorobutadiene, and other organics and metals. The contamination is from several industries established in the late 1800s, including chemical manufacturing plants, scrap metal recycling, log transfer facilities, and shipbuilding. The Port of Tacoma worked to extend the Hylebos Waterway in the 1960s to a three mile-long waterway, 200 feet wide. Today, 167 acres of the 285-acre area that makes up the Hylebos Waterway requires cleanup.
