Thanks to the Delaware Division of Natural Resources and Environmental Control (DNREC), Bellefonte now has an air quality monitoring station at Town Hall. PurpleAir sensors allow communities to monitor air quality at a local level.
The data is displayed as an Air Quality Index (AQI), with a color code indicating levels of concern for human health. The sensors measure a type of air pollution known as particulate matter (PM) and report live data to the Environmental Protection Agency’s AirNow Fire and Smoke Map.
