Jasper PO Air Monitoring Station, Jasper, Indiana | Environmental Monitoring

Jasper PO is an air monitoring station located at the Jasper Post Office in Jasper, Indiana, United States. It is part of the Indiana Department of Environmental Management's Office of Air Quality network, contributing to the state's ambient air quality surveillance. The station is operational and reported data as of December 31, 2024. The station operates under the regulatory framework of the U.S. Environmental Protection Agency's Air Quality System (AQS), which sets standards for criteria pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. Monitoring stations like Jasper PO typically measure a subset of these pollutants to assess compliance with National Ambient Air Quality Standards (NAAQS). The station's siting and equipment follow EPA guidelines to ensure representativeness of local air quality. As part of Indiana's air monitoring network, Jasper PO supports public health protection by providing data used for air quality index reporting and regulatory compliance. The station's location in a mixed urban-industrial area helps characterize exposure for nearby communities. Continuous operation ensures long-term trend analysis and early detection of pollution episodes.

Jasper PO is situated in Dubois County, Indiana, an area with a mix of urban, agricultural, and light industrial activities. The station's monitoring contributes to understanding local air quality impacts from sources such as traffic, manufacturing, and agriculture. Parameter coverage typically includes criteria pollutants, with potential for speciation or meteorological measurements depending on network design. Siting representativeness is critical for capturing population exposure and background levels.
