Air quality today
The air quality in Chartiers Township, Pennsylvania is currently rated as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 11.4 µg/m³ based on two valid observations reported through OpenAQ.
Data for other pollutants are not available at this time. 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 air‑quality record for Chartiers Township includes two pollutant measurements drawn from a single monitoring location. Both ozone (O3) and fine particulate matter (PM2.5) are reported, with the most recent data timestamped 2026-02-11 00:00 UTC, which falls within the last seven days and therefore reflects current conditions.
For ozone, the dataset contains only one value: 0.056 ppm recorded at the Houston‑referenced site on the latest update. Because the minimum, median, and maximum are all identical, there is no observed variation in O3 across the available record. The same pattern holds for PM2.5, which shows a single reading of 11.4 µg/m³ at the same location and time; again, the statistical spread (min, median, max) is zero.
With just one sensor contributing data, coverage across Chartiers Township is limited to that specific point, so spatial differences within the township are not captured in this set. The uniformity of the values indicates that the dataset does not contain multiple observations over time or across different sites that would reveal fluctuations. Consequently, while the timestamps are fresh, the overall picture is sparse: only two pollutant rows exist, both from the same recent measurement, and there are no older or unknown‑age entries to provide a broader historical context. This means that any interpretation of air quality in Chartiers Township should consider that conditions can vary elsewhere in the area and at other times beyond what these single‑point readings show.
