QUEEN VALLEY Air Monitoring Station, Queen Valley, Arizona

QUEEN VALLEY is an operational air monitoring station located in Queen Valley, Pinal County, Arizona, United States. The station is part of the national network of ambient air quality monitors that track criteria pollutants and other atmospheric parameters to ensure compliance with the Clean Air Act. The station operates under the regulatory framework of the U.S. EPA's Air Quality System (AQS), which sets standards for monitoring methods, siting, and data reporting. The reporting agency for this station is Eastern Research Group, which manages data collection and quality assurance. Typical air monitoring stations in Arizona measure pollutants such as ozone, particulate matter (PM2.5 and PM10), carbon monoxide, sulfur dioxide, and nitrogen dioxide, though specific parameters measured at this station are not detailed. Air monitoring stations like QUEEN VALLEY play a critical role in protecting public health and the environment by providing data for air quality index (AQI) reporting, regulatory compliance, and research. The station's location in Queen Valley, a rural area near the Tonto National Forest, contributes to understanding background air quality and regional transport of pollutants.

The Queen Valley area is situated in the Sonoran Desert, with a semi-arid climate and significant seasonal temperature variations. Air quality in this region can be influenced by dust from dry lake beds, agricultural activities, and wildfires, as well as transported pollutants from the Phoenix metropolitan area. Monitoring stations in such settings help distinguish local sources from regional background pollution, supporting effective air quality management and public health advisories.
