Towanda Air Monitoring Station, Monroe, Pennsylvania | USA Environmental Monitoring

Towanda is an air monitoring station located in Monroe, Bradford County, Pennsylvania, United States. It is operated by the Pennsylvania Department of Environmental Protection and contributes to the national ambient air quality monitoring network under the US EPA Air Quality System (AQS). The station is part of a statewide effort to track criteria pollutants and support regulatory compliance with the Clean Air Act. The station's technical scope includes routine sampling of ambient air pollutants, with the most recent sample date recorded as July 2025. As part of the Pennsylvania DEP network, it follows standardized methods for monitoring criteria pollutants such as ozone, particulate matter, and nitrogen dioxide. The station's siting is representative of rural air quality in the northern Appalachian region, providing valuable background data away from major urban emission sources. Environmental monitoring at Towanda supports regional air quality management and public health protection. Data from this station helps assess compliance with National Ambient Air Quality Standards (NAAQS) and informs local air quality forecasts. The station's long-term operation contributes to trend analysis and policy development for air pollution control in Pennsylvania.

The Towanda station monitors ambient air quality in a rural area of northeastern Pennsylvania, where air quality is influenced by regional transport of pollutants from industrial and urban areas, as well as local sources such as agriculture and residential heating. The station's data helps characterize background ozone and particulate levels, which are critical for understanding regional air pollution dynamics. Its location in Bradford County provides representative measurements for the Susquehanna River Valley, supporting the EPA's monitoring network design for rural and remote areas.
