Maricopa's air quality reflects the Sonoran Desert basin south of Phoenix in Pinal County, with vehicle emissions from SR-347 the primary local source in this rapidly growing suburban community. Windblown Sonoran Desert dust contributes PM10 during dust storm events, while the flat desert basin's partial topographic enclosure between the Estrella and Sierra Estrella ranges creates periodic inversion episodes and summer ozone from Phoenix metropolitan traffic affects the entire South Valley corridor.
