DEER Air Monitoring Station, Newton County, Arkansas | US EPA AQS Network

DEER is an air monitoring station located on Highway 16 in Newton County, Arkansas, within the United States. Operated by the Arkansas Department of Energy and Environment, this station is part of the national ambient air quality monitoring network. The station is operational and provides data to the US EPA Air Quality System (AQS), supporting regulatory compliance and public health protection. The station operates under the framework of the US Clean Air Act and EPA monitoring regulations. While specific parameters measured are not detailed, typical rural stations like DEER monitor criteria pollutants such as ozone, particulate matter, or meteorological parameters. The Arkansas Department of Energy and Environment coordinates monitoring efforts to ensure data representativeness and quality assurance. As a rural monitoring station in the Ozark region, DEER provides baseline air quality data away from urban emission sources. This data is essential for understanding regional air quality trends, supporting state implementation plans, and informing public health advisories. The station's long-term operation contributes to the continuity of the national monitoring network.

Located in the Ozark Mountains of Arkansas, DEER monitors air quality in a region characterized by forested landscapes and low population density. The station's rural siting provides background air quality data, helping to distinguish regional pollution transport from local sources. Typical parameters at such stations include ozone and fine particulate matter, which are relevant for assessing visibility and ecosystem impacts in nearby protected areas.
