Whether on land or in the sea, oxygen is critical for sustaining life. Healthy ecosystems depend on it, and the amount of dissolved oxygen in marine environments is one of the ways that scientists measure water quality. Both the research community and the regulatory authorities rely on complex computer models of the Salish Sea to predict dissolved oxygen levels, and key mechanistic drivers of water quality change, such as Nitrogen (N), and Net Primary Production (NPP). Now, the University of Washington Puget Sound Institute and the Salish Sea Modeling Center […]

New sewage-treatment permit would be a step to curbing nitrogen in Puget Sound

Share

In an effort to stem the flow of excess nitrogen into Puget Sound, Washington Department of Ecology has proposed a new type of permit for some 60 sewage-treatment plants operating throughout the region. The flexible permit, called the Puget Sound Nutrient General Permit, aims to hold nitrogen releases close to or below their current levels at most of the treatment plants while offering plant operators options for how to meet those goals. It’s a temporary solution, because the long-term goal is to make significant cuts in the total amount of […]
