Description This quality assurance project plan outlines a 2021 study to evaluate current concentrations of phthalates and non-phthalate plasticizers in freshwater and marine environments throughout the state. Ecology will collect (1) surface water and bottom sediment samples from 16 rivers and lakes during late spring and fall, and (2) suspended particulate matter from three of the rivers during the winter. This study will also analyze phthalates and non-phthalate plasticizers in marine sediments previously collected by Ecology's Puget Sound Sediment Monitoring Program.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
