Description Ecology conducted this 2009-2010 study to address data gaps identified by the Puget Sound Toxics Box Model. Samples were collected from the marine water column and 5 major rivers discharging to Puget Sound and analyzed for various toxic chemicals. Many were present in low concentrations but others were seldom if ever detected.

Marine water concentrations were used to evaluate exchange of toxic chemicals between Puget Sound and the ocean. Most chemicals, except for cadmium, appeared to be exported from Puget Sound. River water concentrations and flows were used to calculate daily loads of toxic chemicals. Additional monitoring for fewer target chemicals, especially in suspended particulate matter, was recommended.
