Air Quality Details (2024–2025)
The Air Quality Index (AQI) measures how clean or polluted the air is. A lower AQI means cleaner air. Main pollutants include particulate matter like PM2.5, ozone, and others regulated by EPA standards.
Air quality data sourced from OpenAQ, aggregating official monitoring stations.
| Yearly Average AQI | National Average AQI | Good Days | Moderate Days | Unhealthy Days | Worst Day AQI | Top Pollutant |
|---|---|---|---|---|---|---|
| 27.8 | 41.4 | 348 | 17 | 0 | 69 (on 7/10/2024) | PM2.5 |
Monthly AQI Trend
Monthly average AQI values over the past year. Lower values are better. Peaks may indicate pollution events.
Facility Compliance
Facility compliance and violation data come from the EPA's ECHO database.
5,000+ monitored facilities
