Legacy of the Past; Challenge for the Future
![]()
When Europeans arrived in Puget Sound they found a rich abundance of resources that had sustained native populations for thousands of years.
New levels of technology allowed exploitation of these resources at a level that was far higher than ever before, and in a few decades almost all the forests had been cut, some species of animals had been harvested to the point of extinction, and many other populations of animals were in severe decline.
Puget Sound and other waterways were also used as places to dump waste. One of the most difficult legacies of our technological society is the toxic chemical burden it has dumped into our air and waters.

Puget Soundkeeper Alliance tries to eliminate toxic chemicals from our waste streams by focusing on regulations that limit their discharge by many sources:
- Industries
- Publically-owned sewage treatment facilities
- Stormwater drainage systems
- Boatyards and shipyards
- Boats and marinas
The Problem:
"Marine life is disappearing from Puget Sound, and fast" (Seattle Post-Intelligencer, October 9, 2006)
"Peter
Lang and his buddies like to go diving by Blake Island, just across
Puget Sound from West Seattle, where they can scoop up delectable
Dungeness crabs. But when they showed up last spring, the lush meadows
of eelgrass where crab like to hide were nearly gone..." (more)

Historical Pollution: A saga of neglect and unintended consequences
Logging and Siltation
The first major impact by Europeans on the Puget Sound environment was through logging. In 1853, Henry Yesler built the first steam driven mill on Puget Sound; by 1883, William Renton noted that nearly all the timber contiguous to Puget Sound had been removed.
Pulp Mills
The first pulp mills in Puget Sound in the 1920's had devastating effects on the shellfish industry in southern Puget Sound. It was said that it was not necessary to use copper-based paint on boats in areas with pulp mill discharges, for nothing would grow there.
Industrial pollution
State permits for wastewater discharges were not required until 1955. Pulp mills and other industrial dischargers began treating their discharges by the early 1960s.
Modern Sources of Pollution
Point Source Pollution
Point source pollution comes mainly from industrial discharges and sewage treatment plants. Though these facilities are required to have permits to discharge into public waters, a very large amount of toxic materials still enter Puget Sound, other waterways, and our state's air. Here is a link to the state's toxic releases, by industry, for 2005, the latest year available (Learn more...)
"Nonpoint source" pollution
Nonpoint source pollution is the polluted runoff from the landscape that runs into Puget Sound after a rainfall. It contains oil and grease, pesticides, industrial chemicals, and many other things that can harm Puget Sound. The Environmental Protection Agency has made nonpoint source pollution a priority.
