| Description | The Department of Ecology’s (Ecology’s) Statewide River and Stream Ambient Water Quality Monitoring Program, led by the Freshwater Monitoring Unit (FMU), has collected monthly water quality samples at over 60 freshwater monitoring sites since the 1950s. The monitored parameters include temperature, pH, dissolved oxygen, streamflow, bacteria, and nutrients. In a subset of these locations, FMU also collects metals data and water hardness data every other month. During the 2023 water year, FMU staff collected select metals and hardness samples each month as well as additional samples of toxic chemicals (toxics) at one location: station 09A190, on the Green River above Kanaskat-Palmer State Park. Monthly sampling for the seven toxics parameters – metals (arsenic, copper, zinc), hardness, and organic pollutants (cPAHs, DEHP, PCBs) – is needed to support pollutant-modeling efforts in the Green/Duwamish River watershed. This addendum to the 2021 Statewide River and Stream Ambient Water Quality Program QAMP describes the additional elements needed for the collection of the proposed toxics. |
