That sounds like a lot of bull scat.
Suspect the sound is a lot cleaner than it was 40-50 years ago when sewer pipes went straight out.

Nope - Sea/Tac only does secondary treatment - you must have tertiary to produce clean water (a very expensive process - one which few cities do). Secondary releases lots of particulate matter, which produces blooms in warm weather. Just ask any one who uses nets to fish about algae blooms and the origins.
