Air Quality Division: Assessment: Air Quality Monitoring

ADEQ conducts ambient air quality monitoring throughout Arizona. Environmental parameters measured in this monitoring network include criteria pollutants (O3, SO2, PM10, PM2.5, CO, and Pb), air toxics, and meteorology. ADEQ's Ambient Air Quality Monitoring Network Plan contains a detailed description of this network. Please visit ADEQ's Annual Reports for information on previous network plans.

In addition to ADEQ's monitoring network, several county air quality agencies also conduct ambient air quality monitoring.
