Ted Walker Park Air Monitoring Station, Tucson, Arizona | United States

Ted Walker Park is an air monitoring station located at 6751 North Casa Grande Highway in Tucson, Arizona, United States. Operated by the Pima County Department of Environmental Quality, this station is part of the US EPA's NEAR ROAD network, which focuses on monitoring air quality near major roadways to assess traffic-related pollution. The station is currently operational and contributes to the national Air Quality System (AQS) managed by the EPA. As a NEAR ROAD monitoring site, Ted Walker Park is equipped to measure criteria pollutants and other parameters relevant to vehicle emissions. The station's siting near a highway ensures representativeness for roadside exposure assessments. Data from this station supports compliance with the National Ambient Air Quality Standards (NAAQS) and informs local air quality management decisions. The reporting agency, Pima County Department of Environmental Quality, ensures data continuity and quality assurance. The environmental significance of Ted Walker Park lies in its role in monitoring air quality in a region influenced by transportation emissions. Tucson's arid climate and growing urban population make roadside monitoring critical for understanding pollution patterns and protecting public health. The station's data helps evaluate the effectiveness of emission control strategies and supports community awareness of local air quality conditions.

Ted Walker Park operates within the regulatory framework of the US EPA's Air Quality System (AQS), which sets standards for criteria pollutants such as ozone, particulate matter, and nitrogen dioxide. As a NEAR ROAD station, it focuses on roadside air quality, capturing emissions from vehicles that may not be representative of regional background levels. The station's siting near a major highway in Tucson provides data on traffic-related pollution, which is a key concern in urban areas with growing vehicle miles traveled. The arid climate of Arizona can influence pollutant dispersion and chemistry, making continuous monitoring essential for understanding local air quality dynamics.
