Overview
Union County #1 Jensen is an air monitoring station in South Dakota, United States, operated by the South Dakota Department of Agriculture and Natural Resources. It provides ambient air quality data for the region.
Union County #1 Jensen is an air monitoring station located at 31986 475th Ave in Union County, South Dakota, United States. The station is part of the state's ambient air quality monitoring network and is operated by the South Dakota Department of Agriculture and Natural Resources. As a fixed-site monitor, it contributes to the characterization of air quality in a rural area near the border with Iowa and Nebraska. The station operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA) Air Quality System (AQS). While specific parameters measured are not detailed, typical rural monitoring stations in the region measure criteria pollutants such as ozone, particulate matter (PM2.5 and PM10), and meteorological parameters. The station's last reported sample date was September 30, 2021, indicating ongoing data collection. Environmental monitoring in this area is important for assessing regional air quality, particularly given the agricultural and industrial activities in the region. The data supports compliance with National Ambient Air Quality Standards (NAAQS) and helps inform public health advisories. The station's location in a rural setting provides background air quality measurements that are valuable for understanding transport of pollutants from urban and industrial sources.
Environmental context
The station is situated in a rural agricultural area of southeastern South Dakota, near the Missouri River and the borders with Iowa and Nebraska. The local environmental context includes emissions from agricultural operations, such as ammonia from fertilizers and livestock, as well as potential contributions from regional industrial sources. Monitoring at this site helps assess background air quality and the influence of transported pollutants from nearby urban centers like Sioux City, Iowa. The data supports the state's air quality management programs and compliance with federal standards.
