Description Nutrient loads, particularly nitrogen, are a potential stressor to Puget Sound. The Washington State Department of Ecology initiated the South Puget Sound Dissolved Oxygen Study to determine whether human sources of nitrogen contribute to low levels of dissolved oxygen in South Puget Sound. A statistical method called "multiple linear regression" was applied to develop daily loads of nutrients from field data collected monthly. This report describes the magnitudes and sources of nitrogen loading into South and Central Puget Sound. The study also calculates natural conditions and compares nitrogen loads in Puget Sound to nitrogen loads in other watersheds.
NOTES Erratum for revised version (September 2023): A typo in Equation 2 on page 18 has been corrected. Original version: "log(C)=". Corrected version: "C=".
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.
