Early Action Area 4 was identified as an area requiring sediment cleanup based on work conducted for the Lower Duwamish Waterway (LDW) Superfund site. This area is located along the eastern bank of the LDW from Slip 4 to the south side of the Jorgensen Forge property. The map shows the location of Early Action Area 4 and the properties located within the area that drains to this area.
The sediments in Early Action Area 4 were contaminated from a variety of sources, both historical and potentially ongoing. Based on the results of sediment sampling, the following chemicals are potential contaminants of concern in Early Action Area 4:
There are two properties adjacent to the Early Action Area 4, Boeing Plant 2 and Jorgensen Forge.
Plant 2 was built on farmland in the 1930’s. Since 1936, Boeing has manufactured airplane parts at Plant 2. This manufacturing process involves many hazardous chemicals including: heavy metals, cyanide, mineral acids and bases, petroleum products, PCBs, and chlorinate solvents. In recent years, activities at Plant 2 have shifted toward research and administration, however some limited manufacturing still continues at this site.
There is contaminated soil, groundwater, and sediment in the Duwamish Waterway adjacent to Plant 2. The site poses potential risk to the health of people, fish, wildlife, and the environment.
The Boeing Company is investigating and cleaning up hazardous waste
contamination at Plant 2 under EPA’s Resource Conservation and Recovery Act
(RCRA). More information on Boeing Plant 2 can be found on EPA’s website:

The Jorgensen Forge site is bordered to the north by Boeing Plant 2, to the
east by East Marginal Way South, and to the south by the Boeing Isaacson
property. The site consists of approximately 21.6 acres in an industrial
area.
Jorgensen manufactures specialized open die steel forgings and rolled aluminum
rings. In addition to steel and aluminum, Jorgensen also processes nickel,
titanium, and specialized alloys.
