The Puget Sound Fact Book brings together statistics and other information about the health and makeup of the Puget Sound ecosystem. Areas of focus include climate change, geography, water quality, habitats, human dimensions and regional species. The fact book was prepared for the Encyclopedia of Puget Sound with funding from the Environmental Protection Agency and the Puget Sound Partnership.

The Lower Duwamish Waterway in Puget Sound was designated a Superfund cleanup site in 2001. Its legacy of contamination predates World War II and the waterway continues to pollute Puget Sound through stormwater runoff.

This report communicates findings of a social science study conducted between July 2013 and December 2014 on a focal domain of human well-being: sense of place.

A 2015 paper in the journal Ecology and Society looks at interdisciplinary approaches to developing conservation targets in Puget Sound. 

Researchers updating a 1980 fish catalog have found evidence of 37 additional fish species in the Salish Sea. This information, accompanied by hundreds of detailed illustrations, is seeding a new reference book expected to gain wide use among scientists, anglers and conservationists. [Editor's note: As of 2019, the list of Salish Sea fishes has grown to 260 species.]

Contaminants of Emerging Concern (CECs) range from pharmaceuticals, personal care products and food additives to compounds used in industrial and commercial applications. These compounds are not typically removed from wastewater and are flushed into waterways throughout the world in significant amounts. This article describes how scientists are measuring the presence of these contaminants along with their potential impacts in Puget Sound, the Columbia River and elsewhere.

An EPA-funded study by the Thurston Regional Planning Council identified recommended strategies and actions to protect and improve water quality and aquatic resources in the Black Lake Basin.
