Overview
10939 East Parker Road is an air monitoring station in Stockton, Illinois, operated under the US EPA National Exposure Research Lab. It contributes to the national air quality surveillance network.
10939 East Parker Road is an air monitoring station located in rural Jo Daviess County, Illinois, United States. The station is part of the US EPA's National Exposure Research Laboratory network, which supports ambient air quality monitoring across the country. As an operational station, it plays a role in tracking criteria pollutants and other atmospheric parameters to inform regulatory compliance and public health. The station operates under the US EPA Air Quality System (AQS) framework, which sets standards for monitoring methods, siting, and data reporting. While specific parameters measured at this site are not detailed, typical rural stations in the US monitor ozone, particulate matter, and meteorological variables. The station's location in a non-urban area provides background air quality data essential for understanding regional pollution transport and baseline conditions. Environmental monitoring at this site contributes to the broader national effort to assess air quality trends and protect public health. Data from such stations support regulatory decisions under the Clean Air Act and help communities understand local air quality. The station's rural siting is valuable for distinguishing local emissions from regional background levels.
Environmental context
The station is situated in a rural area of northwestern Illinois, near the Mississippi River. This location is representative of agricultural and small-town environments, where air quality is influenced by farming activities, regional transport, and occasional industrial sources from nearby urban centers. Monitoring in such settings helps characterize background ozone and particulate levels, which are critical for understanding the effectiveness of emission reduction strategies.
