Details: A herbicide, endothall, was detected at around half the MCL at the entry point to the distribution in the November 2018 sample. (Rainier is already sampling more frequently for another herbicide, diquat.)

Action Needed
Sample for endothall quarterly in 2019.
Reevaluate sampling frequency & treatment based on those results.
