Locations of DEQ Air monitoring locations with Monitoring type and Pollutant.

DEQ's monitoring network measures the levels of five of the six ambient air criteria pollutants identified by the federal Clean Air Act. The criteria pollutants are: 

Particulate matter 
(PM10 = particulate matter less than or equal to 10 microns in diameter; PM2.5 = particulate matter less than or equal to 2.5 microns in diameter)

Carbon monoxide 
Nitrogen dioxide 
Sulfur dioxide 
Ozone 
Lead (Airborne lead is no longer considered a major health threat in most of the U.S. With the phase-out of leaded gasoline and closure of the Bunker Hill Mine, DEQ no longer monitors airborne lead levels.)

The Air Pollution Monitoring program monitors all of the six criteria pollutants. Measurements are taken to assess areas where there may be a problem, and to monitor areas that already have problems. The goal of this program is to control areas where problems exist and to try to keep other areas from becoming problem air pollution areas.
