Why is there no air quality monitor in my neighborhood?

We would love to have air quality monitors every square mile or so, but it's just not practical. So, monitors are placed in locations that can be used to represent a larger area. In your area, there is most likely a monitor to represent the quality of the air you are breathing.

To learn what criteria are used to place monitors, please see


For more information about the monitors in your area, please contact your local air quality office.
