Air Quality Monitoring
ADEQ conducts ambient air quality monitoring throughout Arizona. Environmental parameters measured in this monitoring network include criteria pollutants (lead, ozone, particulate matter — PM10 and PM2.5, carbon monoxide, nitrogen oxides, sulfur dioxide) as well as air toxins. ADEQ also collects meteorological data at sites throughout the state to support the analysis of pollutant data and to provide support for exceptional event reporting.
ADEQ operates ambient air quality equipment for a variety of federal and state monitoring programs. Data collected by these monitors helps:
- determine Arizona’s current air quality status in regards to attaining the Environmental Protection Agency’s National Ambient Air Quality Standards (NAAQS)
- determine current air quality trends
- modeling for new sources of pollution
- air quality forecasters better predict future air quality trends
