As you are aware, the Houghton and Keweenaw area is experiencing very poor air quality conditions. Here are some resources for you to monitor conditions and make the best decisions for your health:
-Purple Air has a network of amateur sensors: https://map.purpleair.com/air-quality-standards-us-epa-aqi?opt=%2F1%2Flp%2Fa10%2Fp604800%2FcC0 #7.56/46.933/-88.494.
-The EPA has the https://www.airnow.gov/ site- but be aware, they only have two sensor in the UP (in Negaunee Twp. and Seney) and their model doesn’t reflect our area very well (currently it says the quality is fine…)
-The EPA also has an index to help explain what each value means: https://www.airnow.gov/aqi/aqi-basics/.
With the current conditions (AQI over 300 ), the EGLE makes the following recommendations: AVOID strenuous outdoor activity, especially if you have heart or respiratory conditions. Keep windows CLOSED to reduce smoke indoors. AVOID SMOKE EXPOSURE. Contact may cause chest tightness, difficulty breathing, and irritation to eyes, nose, and throat.
