King County invited reviewers outside of King County to look at our plans, findings and draft documents throughout the process – from initial scoping in 2012 to publication in 2017.

We wanted to make sure the study’s scientific methods and results would be high quality, thorough, and objective – and useful to others working on water quality in the region.

Science and Technical Review Team

A Science and Technical Review Team reviewed every step of the process. The five members are independent technical experts in water quality, environmental science and engineering. They are not affiliated with King County. They met more than 20 times to review the study plans, findings, and draft documents.

See the Review Team’s final report on the study.
