Air Quality Partnership of the Delaware Valley
The Air Quality Partnership (AQP) is a public / private coalition dedicated to improving air quality in the Delaware Valley through air quality initiatives and advisories. The Partnership implements the Air Quality Action program to notify the public when air quality is forecast to be unhealthy and to encourage the public to take action to reduce air pollution, especially on Air Quality Action days. The AQP is administered by the Delaware Valley Regional Planning Commission.

The AQP provides air quality forecasts for ground level ozone and fine particulate matter (PM2.5). Ozone forecasts are available from May through September. PM2.5 forecasts are provided year-round. Forecasts are provided on this website and also by calling the Air Quality Partnership Information Line at 1.800.872.7261. Check the forecast daily and take the proper actions to reduce pollution and protect your health.
