Revising Water Quality Assessment Policy 1-11

Feb. 12, 2018 - Mar. 28, 2018

We are accepting written comments on the draft revisions of Policy 1-11

For more information visit our Revising the Water Quality Assessment and Policy 1-11 webpage.
Policy 1-11 provides guidance for how we evaluate the water quality data that we receive.  We collect this data to determine if water bodies are polluted and decide if further action is needed.   We use data that meets this policy in our Water Quality Assessment to track how clean the rivers, lakes, and marine waters are in Washington.
