Saving Puget Sound

Puget Sound Water Quality Activities

Puget Sound needs our help. Toxic chemicals are concentrating in the water and entering the food chain. Low oxygen levels caused by nitrogen discharged from septic tanks, sewage treatment plants and other sources are threatening the Sound. The water quality program is working to prevent water pollution, clean up water pollution to restore aquatic habitat, and help communities make sustainable choices.

Controlling Toxic Chemicals in Puget Sound

Dissolved Oxygen in Puget Sound

Information on what Ecology's Water Quality program is doing to investigate dissolved oxygen and nutrient issues in Puget Sound.

Ocean Acidification and climate change

Ecology and its partners are addressing ocean acidification in the marine waters of Washington State.

Ocean Acidification Modeling

Ecology and its partners have developed an approach for determining the relative contributions of regional and global human impacts.

Puget Sound Ecosystem Monitoring Program

Information on the Puget Sound Coordinated Monitoring Program. The goal of this effort is to provide credible and useful information about the Puget Sound Basin’s freshwater and marine environments and aquatic habitat.

Puget Sound Initiative (PSI) Site Cleanups

In response to the Puget Sound Initiative and increased funding, Ecology has accelerated its efforts to clean and restore contaminated sites within identified priority bays. These areas are the cornerstones of Ecology's approach to protect and restore Puget Sound.
