The ENVVEST Project is designed to develop and demonstrate strategies for protecting and improving the health of aquatic ecosystems in partnership with the U.S. Environmental Protection Agency and the Washington State Department of Ecology. The primary objectives of the ENVVEST Project serve to establish environmentally protective levels for chemicals-of-concern and incorporate them into decision making processes. The objectives are achieved through the use of sound ecological science and risk-based management. The ENVVEST Ambient Monitoring Program (stewarded by long-standing technical stakeholders, PNNL and NIWC) is a singular component of the Project and should be considered holistically within ENVVEST’s large scale environmental monitoring efforts. The current technical report summarizes the status of ENVVEST efforts toward monitoring nutrients and dissolved oxygen in the marine waters of Sinclair and Dyes Inlets, Puget Sound, WA.
