Air quality today
The air quality in Drummondville today is classified as Good. The primary pollutant identified for this assessment is PM2.5 (fine particles).
Measurements show a PM2.5 concentration of 5.8 µg/m³ based on two valid observations recorded by OpenAQ. This indicates that the current level of fine particulate matter falls within the range associated with the Good category. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.
Latest sensor values
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 Drummondville air‑quality dataset currently includes two measured pollutants: ozone (O3) and fine particulate matter (PM2.5). Both values come from a single monitoring site, identified as “Drummondville – Stad,” which supplies one row of data for each pollutant. In total there are two rows in the record, meaning that every available measurement is tied to this lone station.
All observations are recent: the latest update timestamp for both O3 and PM2.5 is 2026‑02‑10 22:00 UTC, placing them well within the three‑day freshness window used by the source platform. No older or unknown‑age entries appear in the set, so the data reflects conditions at a single point in time rather than a longer historical series.
The numeric values are uniform across each pollutant’s row. Ozone is reported at 0.035 ppm, with the minimum, median, 10th percentile and 90th percentile all equal to that figure, indicating no observed variation within the dataset. Likewise, PM2.5 registers a constant 5.8 µg/m³ across its statistical summary. Because there is only one measurement per pollutant, the typical (median) value coincides with both the minimum and maximum, and no spread can be derived from this snapshot.
These characteristics mean that while the data are fresh and come from an officially recognized sensor, they provide a very limited view of air quality across Drummondville. Conditions can differ in other neighbourhoods or at other times of day, so the single‑station snapshot should be understood as a point reference rather than a comprehensive picture of citywide air quality.

Data notes
The data shown for Drummondville reflects two valid measurements and is updated within 3 days, with the latest values recorded on 2026‑02‑10 at 22:00 UTC. This snapshot provides a brief view of current conditions; however, air quality can differ across neighborhoods and change throughout the day, so local variations may not be captured in these figures.
