Air Quality

One of primary duties of the Regional Air Pollution Control Agency is to monitor the air quality in our six-county jurisdiction and compare our air quality against U.S. EPA’s National Ambient Air Quality Standards (NAAQS), which are set to be protective of public health.

In order to do this, we operate a network of air quality monitors. Currently, the network includes 30 monitors, dispersed over 11 locations, in five of our six counties. RAPCA monitors the following pollutants:

• ozone,
• particulate matter (2.5 microns and 10 microns)
• carbon monoxide
• sulfur dioxide
• lead, and
• nitrogen oxides

If you're interested in monitoring data for the pollutants above, please visit our air quality data section. To view today's air quality graphs, click here.
