Information on outdoor air quality monitoring for every county in the United States? Yes, I can provide that.
In the United States, there are roughly 3,000 counties, but only about one-third of them have air quality monitoring data [1][3]. This means that approximately 2,000 counties do not have access to comprehensive air quality data, leaving many communities without crucial information about their local environment.
The lack of outdoor air monitors in U.S. counties is primarily due to resource limitations, regulatory requirements, and prioritization based on population density and pollution sources. The Clean Air Act requires states to maintain monitoring networks for key pollutants in areas where air pollution is a concern, generally focusing on metropolitan or industrial regions with higher populations or emissions [1][3]. As a result, fewer monitors are found in rural or less populated counties that may have lower pollution risks.
If you're wondering why your specific county lacks an air monitor, there are several steps you can take to find out:
- Check the EPA's Air Quality System (AQS) database or AirData website, which provide comprehensive data on monitoring locations and air quality statistics for counties and cities across the U.S. [3]
- Contact your state or local environmental agency or air quality agency (such as a state environmental commission or local clean air agency) to inquire about monitoring plans or gaps. Agencies sometimes have strategic or budgetary reasons for choosing where to place monitors [1][5]
- Review state air quality network information online to see monitoring coverage and data availability. For example, Texas publishes detailed info about its network on the Texas Commission on Environmental Quality (TCEQ) website [1]
- Speak to your county public health department or environmental office; they may offer insight into monitoring decisions or any plans to expand monitoring in the future [5]
It's worth noting that the outdoor air monitoring data summaries only go back to 1980, and it's unclear if older data is available. Additionally, the location or distribution of outdoor air monitoring data summaries that go back to 1980 is not specified. The accessibility of outdoor air monitoring data for periods beyond the summaries that go back to 1980 is not guaranteed.
The majority of U.S. counties do not have access to real-time air quality data, and the timeframe for when outdoor air monitoring data will be available is unknown. The reasons for the lack of availability of older and recent outdoor air monitoring data are not addressed.
The lack of air quality monitoring data in U.S. counties is a significant issue, as it leaves many communities without the ability to make informed decisions about their health and environment. By following the steps outlined above, you can gain a better understanding of your county's air quality and advocate for improved monitoring where necessary.

The absence of air quality monitors in U.S. counties might impact the health and wellness of residents, as many communities are left uninformed about their local environment. This gap in environmental-science data could potentially origin from resource limitations, regulatory requirements, and prioritization based on population density and pollution sources.
