BP2 is located on the east bank of the Duwamish Waterway in both Seattle and Tukwila, Washington. The facility was built in the late 1930’s and was a major aircraft manufacturing facility during World War II. PCB’s from large electricity generators and transformers were released at Plant 2 and into the Lower Duwamish Waterway. A wide range of other hazardous chemicals are found in the soil, groundwater, and sediment. As an Early Action site, this project involved dredging part of the Early Action area as a precursor to the Superfund clean-up of the entire Lower Duwamish Waterway. WaterTectonics deployed two 300gpm WaveIonics electrocoagulation systems to remove solids, heavy metals, and PCB’s from the dredge return water. In addition, the WaterTectonics field service team also provided mobilization, operator training, and ongoing operations support.
