| Description | Portions of South and Central Puget Sound are on the Clean Water Act Section 303(d) list of impaired waters for dissolved oxygen (DO). Human sources of nutrients can increase algae growth, which can decrease oxygen as the additional organic matter decays. Computer modeling tools were used to isolate the impacts of human contributions. The model predicts that current human nutrient loads from marine point sources and watersheds, as well as external current anthropogenic loads, are causing DO to decline by as much as 0.4 mg/L in portions of Totten, Eld, Budd, Carr, and Case Inlets, and East Passage, which violates the standards. Reducing these nutrient sources would decrease the magnitude and extent of DO depletion. |
