Indpls.- E. 16th St. Air Monitoring Station, Indianapolis, Indiana

Indpls.- E. 16th St. is an air monitoring station located at the Naval Avionics Center in Indianapolis, Indiana. Operated by the Indiana Department of Environmental Management's Office of Air Quality, this station is part of the broader US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other atmospheric parameters across the United States. The station operates under the regulatory framework of the Clean Air Act and EPA monitoring requirements. As an AQS site, it likely measures pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, though specific parameters are not detailed. The station's location in an urban-industrial area provides representative data for population exposure and regulatory compliance. Environmental monitoring at this site supports air quality management in the Indianapolis metropolitan area, contributing to public health protection and attainment demonstrations for National Ambient Air Quality Standards (NAAQS). Continuous operation ensures long-term trend analysis and informs local emission reduction strategies.

Indianapolis is a major urban and industrial center in the Midwest, with air quality influenced by transportation, manufacturing, and power generation. The station's location at the Naval Avionics Center provides data on urban background and industrial emissions. Monitoring criteria pollutants here helps assess compliance with NAAQS and supports the State Implementation Plan for Indiana.
