Who were those orange-vested kids seen alongside Edmonds’ creeks and the marsh last week? According to Joe Scordino, a retired NOAA fisheries biologist, they were Edmonds-Woodway High School students from the Students Saving Salmon club, monitoring water quality.

As part of their monthly monitoring project, in rain or shine, the students collected data at 15 stream sites in Edmonds to determine dissolved oxygen, temperature, pH, and other water quality parameters. They also collected winter season water samples that were sent to a lab for heavy metal and petroleum product analysis, said Scordino, who serves as a club adviser.

This spring, students will summarize the data collected monthly since last fall and present a report on Edmonds water quality to the Edmonds City Council and the community.
