Puget Sound is suffering from emergency levels of toxic and nutrient pollution. That pollution is causing wholesale food web changes, dangerously low levels of dissolved oxygen, shells thinning from ocean acidification, and toxic threats to orca whales, Chinook salmon, and Dungeness crabs. A lot of this toxic and nutrient pollution is from treated municipal sewage. From our sinks and toilets. Only one sewage treatment plant near Puget Sound is required to use modern technology. The rest use something called “secondary treatment.” That technology was invented in the early 1900s, and it doesn’t remove nutrients or toxic pollution from sewage. Washington state’s sewage treatment methods are older than: zippers for clothing, the ballpoint pen, the Ford Model T, filtered coffee, the discovery of antibiotics and medical insulin to treat diabetes, the iron lung machine, ladies’ bras, crossword puzzles, the pop-up toaster, the electric guitar, and the entire history of rock and roll. But a newer and far more modern treatment method does remove nutrients and toxic pollution from sewage. It’s called “tertiary sewage treatment” and it’s about 30 years old. Washington’s Department of Ecology requires Spokane County to use this treatment method. So why doesn’t the state require other sewage treatment plants in Puget Sound to use the technology? Modern sewage treatment would put Puget Sound on the path toward healing. It’s the obvious choice for a healthier Sound, and it’s long overdue.
