Abstract

Outfalls that discharge residential, commercial, and industrial wastewater as well as upland stormwater are abundant throughout Puget Sound, WA (USA). However, there are limited data or few regulatory guidelines related to the management of outfalls, and practically no oversight on the impacts outfall infrastructure and discharge have on critical nearshore habitats (e.g., eelgrass and macroalgae). Research has demonstrated seagrasses uptake nutrients, metals and organic contaminants with varied physiological effects, but little is known about the concentration of these substances in eelgrass in the Pacific Northwest and more specifically, in greater Puget Sound. Basic nutrients, nitrogen and phosphorus, are known to be abundant in the Sound, but whether these substances or other contaminants are at levels that cause adverse effects and/or toxicity to eelgrass is unknown. In an effort to meet its land stewardship responsibilities and to support the Puget Sound Partnership’s goal to increase eelgrass area by 20% by 2020, the Washington State Department of Natural Resources has identified a need to improve its understanding of key seagrass stressors in greater Puget Sound. The current project conducted a baseline assessment of nutrients, metals, and organic contaminants in eelgrass at 15 sites across Puget Sound and at one additional site where modifications in an outfall are anticipated. The overview of the project components, sample sites, methods, and preliminary results will be presented.

The assessment of nutrient, metal, and organic contaminant concentrations in eelgrass (Zostera marina L.) in Puget Sound, WA (USA): A project overview

Room 608-609

Outfalls that discharge residential, commercial, and industrial wastewater as well as upland stormwater are abundant throughout Puget Sound, WA (USA). However, there are limited data or few regulatory guidelines related to the management of outfalls, and practically no oversight on the impacts outfall infrastructure and discharge have on critical nearshore habitats (e.g., eelgrass and macroalgae). Research has demonstrated seagrasses uptake nutrients, metals and organic contaminants with varied physiological effects, but little is known about the concentration of these substances in eelgrass in the Pacific Northwest and more specifically, in greater Puget Sound. Basic nutrients, nitrogen and phosphorus, are known to be abundant in the Sound, but whether these substances or other contaminants are at levels that cause adverse effects and/or toxicity to eelgrass is unknown. In an effort to meet its land stewardship responsibilities and to support the Puget Sound Partnership’s goal to increase eelgrass area by 20% by 2020, the Washington State Department of Natural Resources has identified a need to improve its understanding of key seagrass stressors in greater Puget Sound.
