| Short Description |
Twelve open-water sites in south Puget Sound and one intertidal area in inner Budd Inlet were re-assessed in 2005 for previous violations of water quality standards. Water quality violations included PCBs and bis(2-ethylhexyl)phthalate (BEHP) in sole and rockfish as well as several PAHs in clams from the former Cascade Pole clean-up site in inner Budd Inlet. The results of the study were needed to determine if these waterbodies should remain on the federal Clean Water Act Section 303(d) list of impaired waterbodies. Pentachlorophenol, dioxins, and furans were also analyzed at the Cascade Pole site. (Also see abstract below) | |||

| Abstract | Long Description |
Twelve open-water sites in south Puget Sound and one intertidal area in inner Budd Inlet are on the federal Clean Water Act Section 303(d) List for violations of water quality standards. Listings include total polychlorinated biphenyls (PCBs) and bis(2-ethylhexyl)-phthalate (BEHP) in sole and rockfish. Listings also include polynuclear aromatic hydrocarbons (PAHs) in clams from the former Cascade Pole cleanup site in inner Budd Inlet. Sole and mussels were collected from these sites and analyzed by the Department of Ecology to assess the appropriateness of the 303(d) listings. Concentrations of PCBs in Puget Sound sole were low but exceeded the National Toxics Rule (NTR) criteria at all but one site. BEHP was not detected and therefore did not exceed the NTR criteria. It was recommended to continue listing PCBs but to change BEHP from Category 5 (On the 303[d] List) to Category 1 (Meets Tested Standards). Concentrations of PAHs in mussel tissue from the Cascade Pole cleanup site were significantly lower than previous results but still exceeded NTR criteria. Four currently 303(d)-listed PAH chemicals - benzo(a)anthracene, benzo(b)fluoranthene, benzo(k)fluoranthene, and chrysene - were found to exceed the NTR criterion of 0.93 ug/Kg ww. Two others - benzo(a)pyrene and indeno(1,2,3-cd)pyrene - also exceeded NTR criteria. It is recommended that all six of these chemicals be included in Category 5 of the 303(d) List. Pentachlorophenol, dioxins, and furans from the Cascade Pole site were also analyzed, even though there were no previous 303(d) listings for these chemicals at the site. Pentachlorophenol was not detected. The dioxin congener 2,3,7,8-TCDD was found to exceed NTR criteria and was recommended for Category 5. |
