The purpose of this task is to evaluate the concentrations of toxics chemicals in the marine waters of Puget Sound and the exchange of those chemicals between the Sound and the Pacific Ocean. Marine water will be collected seasonally at two depths from three locations in the Straits of Juan de Fuca and Georgia and from four locations within Puget Sound. In addition, Ecology will collect and analyze freshwater seasonally from the mouths of five major rivers discharging to Puget Sound to evaluate the loading of toxic chemicals to Puget Sound and the partitioning of those chemicals between the water and suspended sediments. Both whole water and particulates will be analyzed.
Expected Outcome: Credible estimate of toxic chemical fluxes for use in the Puget Sound Toxics Box Model to estimate chemical gains and losses between Puget Sound and the Pacific Ocean.
The Department of Ecology's Environmental Assessment Program will oversee this sub-task.
