Water Quality Assessment

This is another in the series of guest posts authored by the consultants we work with and trust. Owen Reese is a Water Resources Engineer at Aspect Consulting approached us and offered to provide Aspect’s perspective on Ecology’s efforts to update its Water Quality Assessment for freshwater. We eagerly took Owen up on the offer because this work by Ecology has the potential to impact a number of dischargers throughout Washington State and fits well into Science Law and the Environment’s editorial goal of analyzing the intersection of science, law, and policy.

The remaining sessions are: April 15 in Yakima, and April 16 in Spokane Valley. I attended the first session in Edmonds on April 7.
