UTM COORDINATES = INLET PROBE LOCATION is an operational air monitoring station located at 126 East Tabernacle, St. George, Utah, within Washington County. The station is managed by the Utah Department of Environmental Quality and contributes to the national ambient air quality monitoring network under the US EPA Air Quality System (AQS). St. George is situated in a semi-arid region near the convergence of Utah, Arizona, and Nevada, where air quality can be influenced by local urban emissions, dust from surrounding desert areas, and seasonal inversions. The station operates under the regulatory framework of the US Clean Air Act, which mandates monitoring of criteria pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. While specific parameters measured at this site are not detailed, typical air monitoring stations in Utah focus on ozone and PM2.5 due to regional concerns about ground-level ozone in the summer and fine particulate matter during winter inversions. The Utah Department of Environmental Quality ensures siting representativeness and data quality through standard EPA protocols. This monitoring station plays a key role in protecting public health and informing air quality management decisions in the growing St. George metropolitan area. Data from this station supports the EPA's Air Quality Index (AQI) reporting, helps identify pollution trends, and guides regulatory actions to maintain compliance with National Ambient Air Quality Standards (NAAQS). The station's location in a rapidly urbanizing area makes it valuable for assessing the impact of development on local air quality.
Environmental context
St. George is located in the Great Basin desert, characterized by hot summers and mild winters, with air quality challenges including ozone formation during high-temperature periods and PM2.5 accumulation during winter inversions. The region's growing population and vehicle emissions contribute to pollutant levels. Monitoring stations like this one are critical for tracking compliance with EPA standards and providing data for public health advisories. The Utah Department of Environmental Quality operates a network of stations to characterize air quality across diverse geographic and climatic conditions.
