Note: The Air Quality Index (AQI) is an index for reporting daily air quality. EPA calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide. The AQI runs from 0 to 500. The higher the AQI value, the greather the level of air pollution and the greather the health concern. There are six AQI categores: "Good" The AQI is between 0 and 50. Air quality is considered satisfactory; "Moderate" the AQI is between 51 and 100. Air quality is acceptable; "Unhealthy for sensitive groups" When AQI values are between 101 and 150, member of sensitive groups may experience health effects; "Unhealthy" When AQI values are between 151 and 200 everyone may begin to experience health effects; "Very Unhealthy" AQI values between 201 and 300 trigger a health alert; "Hazerdous" AQI values over 300 trigger health warnings of emergency conditions; Data covers the entire county unless noted otherwise; (1) Data covers the entire county; (2) Number of days with AQI in 2012
