Autumn is beginning to reacquaint itself with Oregon; the light doesn’t last so long as it did a month ago, and the evenings are beginning to cool. The water temperatures haven’t been as warm, and when I waded out into the Columbia River when I visited Sauvie Island earlier this week, my skin was rather less tolerant of the chill. Still, I was able to take the necessary samples and readings for my final water testing of the year for Columbia Riverkeeper. While I’ve been taking care of this beach since December 2012 for SOLVE, this is the first summer I was able to test the waters monthly, measuring temperature, pH, and dissolved oxygen, among others. These readings help to determine whether there have been any significant changes to the water quality, which can lead to an investigation of the source of the changes if need be.
