| Short Description |
This report summarizes the readily available data collected since 1995 on selected toxic chemicals in the water column of the Strait of Juan de Fuca, Strait of Georgia, and Puget Sound. Water column data on toxic chemicals were identified as an important component of an overall strategy to control chemical inputs to Puget Sound. Data were sought for selected toxic heavy metals, persistent organic compounds, pesticides, and hormone disruptors. There are much more useful data on metals than on organic compounds. Further sampling is recommended to fill the data gaps. (Also see abstract below) | |||

| Abstract | Long Description |
This report summarizes the readily available data collected since 1995 on selected toxic chemicals in the water column of the Strait of Juan de Fuca, Strait of Georgia, and Puget Sound. The Washington State Department of Ecology compiled a total of 15,000 potentially relevant sampling records. These data are needed to estimate the flux (movement) of toxic chemicals between the ocean boundary and Puget Sound. The data will be used in the Puget Sound Toxicant Transport and Fate Box Model which will predict the effects of contaminant loadings on concentrations of toxic chemicals in the water column, fish, and other animals. Data were sought for selected toxic heavy metals, persistent organic compounds, pesticides, and hormone disruptors. The metals data appear adequate to estimate fluxes at the ocean boundary and to provide representative water column concentrations for some cells of the Puget Sound box model. There is much less data on organic contaminants. The most useful data are for polychlorinated biphenyls (PCBs) and polybrominated diphenylethers (PBDEs) in the Strait of Georgia. It is recommended that sampling be conducted for all of the organic chemicals and chemical groups of concern in the Strait of Juan de Fuca and Strait of Georgia boundary waters, as well as selected Puget Sound locations. There are gaps in the metals data for the Strait of Juan de Fuca, South Sound, and Hood Canal that should also be addressed through sampling. |
