Ecology shares plan to clean up Puget Sound nutrient pollution

The Washington State Department of Ecology is seeking public input on its draft Puget Sound Nutrient Reduction Plan to combat nutrient pollution harming marine life. The increasing population in Western Washington contributes to excess nitrogen levels from human sources, including wastewater and fertilizers, which leads to low oxygen levels in the Sound. These low oxygen conditions disrupt the marine food web, adversely affecting species like salmon and orca. The draft plan outlines actions to be taken by 2050, including updating water quality permits and establishing cleanup strategies for watersheds feeding into the Sound. David Giglio, who manages Ecology’s water quality program, noted that the plan is crucial for regional recovery efforts.

The public is invited to provide feedback to help shape the strategies for cleaner water. The plan utilizes the Salish Sea Model to predict how changes in nitrogen levels affect oxygen in the water. As nutrient pollution remains a significant issue nationwide, this plan serves as a model for similar efforts across the country.
