Bonne Terre Air Monitoring Station | Missouri, United States

Bonne Terre is an air monitoring station located at 15797 Highway D, Bonne Terre, Missouri, United States. The station is operational and contributes to the US EPA Air Quality System (AQS) monitoring network, which tracks criteria pollutants and other atmospheric parameters to assess ambient air quality. The station reports to Eastern Research Group, a contractor supporting EPA's monitoring programs. While specific parameters measured are not detailed, typical AQS stations monitor pollutants such as ozone, particulate matter (PM2.5 and PM10), carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. The station's location in a rural area of Sainte Genevieve County provides representative background air quality data for the region. As part of the national monitoring network, Bonne Terre supports regulatory compliance with the Clean Air Act and helps inform public health advisories. Its data contributes to long-term trends analysis and air quality index reporting for Missouri communities.

The station is situated in a rural area of eastern Missouri, near the St. Francois Mountains. Local air quality may be influenced by industrial activities in the region, including mining and manufacturing, as well as agricultural emissions. Monitoring at this site helps characterize background pollutant levels and supports the EPA's goal of protecting public health and the environment through the National Ambient Air Quality Standards (NAAQS).
