7.01 Air Quality

This page includes data on air quality from the U.S. Environmental Protection Agency. The Air Quality Index (AQI) is used to report the daily level of pollution in the air, including ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. An AQI between 0 and 50 is considered good air quality. Values between 51 and 100 are considered moderate pollution levels. A value between 101 and 150 is unhealthy for “sensitive groups,” including people with heart or lung disease, older adults, and children. An AQI greater than 150 is considered unhealthy for everyone.
