AIR QUALITY

The Maricopa County Air Quality Department strives to provide clean air to all Maricopa County residents so they can live, work and play in a healthy environment.

The department however, does much more than monitor air quality. In addition to measuring particulate matter and carbon monoxide levels in the air, the department also enforces compliance from industrial and residential users, issues permits, creates air pollution rules and ordinances and manages a trip reduction program designed to reduce the number of single occupancy vehicles on the road.

The air monitoring division provides real-time air quality readings through an interactive map. The department works with the Environmental Protection Agency (EPA) to operate 23 air quality sites around the county that will monitor the amount of harmful pollutants in the air, including carbon monoxide, lead, nitrogen dioxide, ozone and sulfur dioxide.  For related content, see the downloads below.
