Air Quality - City of Longmont Skip to main content

  

 

Air QualityAir quality impacts our quality of life in numerous ways. Poor outdoor air quality can decrease visibility and negatively impact our respiratory health. Outdoor air pollution is generated by fires, construction, and street maintenance, as well as chemical pollutants generated by vehicles, oil and gas operations, and even spilling gas at the fueling station.

Learning about Air Quality

6 flags ranging from green to very dark red, showing air quality. Green is good, yellow moderate, orange unhealthy for sensitive groups, red unhealthy, dark red very unhealthy, very dark red hazardous

Front Range Air Quality

Each day, you can find out what the air quality is like by checking the Air Quality Index (AQI) for where you live. The Environmental Projection Agency calculates the AQI, which tells you when high levels of air pollution are predicted for the day. You can use that information to plan for safe and healthy physical activity.

Longmont and the surrounding areas are part of the Denver Metro/North Front Range reporting area.

Checking the AQI is easy — anyone can do it! All you need is your ZIP code. Look up the local AQI on AirNow.gov

Longmont Air Quality

As directed by City Council, and in accordance with the objectives of the Sustainability Plan, an air quality monitoring program has been developed to monitor oil and gas emissions, and the overall air quality in the City of Longmont.

Air monitoring instruments are located at Union Reservoir and Vance Brand Airport. Air monitors track the presence of compounds such as carbon dioxide, ozone, nitrogen oxides, methane, benzene, and particulate matter. To learn more about the air quality monitoring program, check out our interview video at the top of the page featuring Dr. Jane Turner and Dr. Detlev Helmig.

Longmont’s preliminary air quality data is available in near real-time to interested residents. Note: The air quality dashboard is best viewed using Google Chrome. Questions about interpretation of the air quality data should be directed to the air quality contractor, whose contact information can be found on the dashboard site.
