Freels/Oak Ridge Air Monitoring Station, Oak Ridge, Tennessee

Freels/Oak Ridge is an air monitoring station located on Freel's Bend Road in Oak Ridge, Tennessee. It is part of the state's ambient air quality monitoring network, operated by the Tennessee Division of Air Pollution Control. The station contributes to the US EPA's Air Quality System (AQS), which tracks criteria pollutants and other parameters to assess compliance with National Ambient Air Quality Standards (NAAQS). The station's last reported sample date is June 30, 2025, indicating ongoing operations. As a fixed-site monitor, it collects data on pollutants such as ozone, particulate matter, and others relevant to the region. The station's siting follows EPA guidelines to ensure representative sampling of local air quality, particularly in the Oak Ridge area, which has a history of industrial and research activities. Environmental monitoring at this station supports public health protection by providing data used for air quality index (AQI) reporting and regulatory compliance. The data also informs local and regional air quality management strategies, helping to identify trends and guide emission reduction efforts in Tennessee.

The Oak Ridge area is home to the Oak Ridge National Laboratory and former nuclear facilities, contributing to a complex industrial and research landscape. Air monitoring here focuses on capturing representative pollutant levels, including ozone and particulate matter, which are influenced by both local emissions and regional transport. The station's data supports the EPA's regulatory framework under the Clean Air Act, ensuring that ambient concentrations remain within NAAQS limits.
