What the data includes

The current station data listed for this city is focused on particulate matter (PM). In Colville, Washington the available OpenAQ records include two measured pollutants: PM10 and PM2.5. Both are reported from a single monitoring location identified as “Colville‑E 1st St,” so the dataset reflects one row per pollutant. The most recent update for each pollutant was recorded on 2026-02-10 23:00 UTC, which falls within the “updated within 7 days” freshness category, indicating that the latest values are relatively current.

Across the two pollutants the reported concentrations show no variation in this snapshot: PM10 is consistently 44.0 µg/m³ and PM2.5 is consistently 5.0 µg/m³, with the minimum, median, and maximum all equal to those figures. Because only one station contributes data, there is limited spatial coverage and no range of values to illustrate variability over time or across different parts of the city. Consequently, while the timestamps are fresh, the single‑site nature means the numbers represent a very narrow view of air quality in Colville and may not capture conditions elsewhere or changes that occur after the last update.
