DOUGLAS CITY PARK Air Monitoring Station, Douglas, Arizona | Environmental Monitoring

DOUGLAS CITY PARK is an operational air monitoring station located at 15th St Park in Douglas, Cochise County, Arizona, United States. The station is part of the U.S. EPA's Air Quality System (AQS) network, which monitors ambient air quality to ensure compliance with National Ambient Air Quality Standards (NAAQS). As a fixed-site monitor, it contributes to the regulatory framework established under the Clean Air Act. The station likely measures criteria pollutants such as ozone, particulate matter (PM2.5 and PM10), carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead, as well as meteorological parameters like wind speed and direction. These measurements support local and regional air quality assessments, particularly given Douglas's location near the U.S.-Mexico border, where cross-border pollution transport may be a concern. Environmental monitoring at this station provides critical data for public health protection and regulatory compliance. The data helps inform air quality alerts, emission reduction strategies, and long-term trend analysis. As part of the broader Arizona monitoring network, DOUGLAS CITY PARK supports the state's efforts to maintain healthy air quality for residents and ecosystems in the region.

Douglas, Arizona, lies in a semi-arid region near the Mexican border, where air quality can be influenced by local industrial activities, vehicular emissions, and dust from dry conditions. The station's location in a city park provides representative sampling of urban background air. Monitoring criteria pollutants and meteorology is essential for assessing compliance with NAAQS and protecting public health, especially in a border community where cross-border pollution sources may contribute to ozone and particulate matter levels.
