We know a lot about smoke at Aprovecho and spend a lot of our time and energy working on solutions to keep it out of people’s lungs. But in the past few days we’ve gotten more personal experience than ever with extremely high and pervasive levels of PM2.5. Wildfires are burning hundreds of thousands of acres of Oregon forests and the wind is from the east, filling the western part of the state with heavy smoke. Yesterday at 6pm the Cottage Grove air quality monitoring station registered 807.1 µg/m3 of PM2.5! Fortunately, it’s currently at 232.2 µg/m3. Just breathing has been difficult, even indoors.
