The air quality in Columbia, Tennessee is currently classified as Moderate. The primary pollutant measured is PM2.5. The latest reading shows a PM2.5 concentration of 32.9 µg/m³. The reported 32.9 µg/m³ corresponds to the reference value used for the current evaluation. The assessment is based on 34 valid measurements collected across the city. The measurement count of 34 reflects the number of valid data points incorporated into the analysis. All observations were recorded during the same reporting period.
Data is shown via OpenAQ. No PM10 measurement was reported for this assessment. The dataset does not include a PM10 reference value. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

PM categories follow US EPA AQI breakpoints, shown here as an estimate derived from the latest valid measurements (this project does not compute EPA NowCast/24-hour AQI yet).
What the data includes
The current station data listed for this city is focused on particulate matter (PM). Only one pollutant is represented – fine particulate matter (PM2.5) – and the dataset contains a single station record. The most recent measurement was recorded on 2026-02-10 23:00 UTC, which places the data within the last 30 days but not within the past week or day. No additional rows are flagged as old or unknown, so the single entry is the only source of recent information for Columbia, Tennessee.
Because there is just one observation, the reported concentration is a single value of 4.8 µg/m³, with the minimum, median, and maximum all identical. This lack of variation means there is no spread to describe across time or locations. The dataset’s coverage is therefore very limited: one station, one reading, and a timestamp that is more than a week old. Consequently, while the figure provides a snapshot of PM2.5 at that moment, conditions in other parts of the city or at more current times may differ.
