Seward Park in Seattle, Washington, needs citizen volunteers to conduct water chemistry tests during visits to the park.
Participants will use water chemistry test kits to monitor phosphates, dissolved oxygen, nitrates/nitrites, pH, and temperature at three locations around Seward Park.
After a short training course, volunteers are welcome to check out a kit and run the analysis any time. The more data, the better! Volunteers can even conduct tests during a lovely walk around the park -- it's exercise with a subplot!
