Near Road Air Monitoring Station, Washington, District of Columbia | Environmental Monitoring

Near Road is an air monitoring station located at 3600 Benning Road N.E. in Washington, District of Columbia, United States. It is part of the NEAR ROAD network and is operated by the Department of Energy & Environment, District of Columbia. The station is operational and contributes to the US EPA Air Quality System (AQS) monitoring network. The station likely measures criteria pollutants such as carbon monoxide, nitrogen dioxide, and particulate matter, which are common in near-road environments. Its siting near a major roadway allows for representative monitoring of traffic-related air pollution. The station reports to the Department of Energy & Environment, which oversees air quality compliance with National Ambient Air Quality Standards (NAAQS). As part of the District of Columbia's monitoring network, Near Road supports public health by providing data for air quality index (AQI) reporting and regulatory assessments. Its location in an urban area with high traffic density makes it valuable for understanding local exposure patterns and informing transportation and environmental policies.

The station's near-road siting is designed to capture pollutant gradients from vehicle emissions, which is critical for assessing population exposure in urban corridors. Washington, D.C. experiences traffic congestion, and monitoring at this location helps evaluate compliance with NAAQS for nitrogen dioxide and particulate matter. The data supports the District's air quality management plans and contributes to regional airshed modeling.
