Monitoring Network

The Kansas Department of Health and Environment - Bureau of Air monitors ambient air for criteria pollutants (carbon monoxide, ozone, sulfur dioxide, nitrogen dioxide, lead, and particulate matter) in accordance with regulations set forth in the federal Clean Air Act.

Wichita has been in compliance with all six criteria air pollutants since 1989. The criteria pollutants are the only ones for which National Ambient Air Quality Standards (NAAQS) have been established by EPA. Based on recent scientific heath effects studies, EPA last revised the ozone standard in 2008 and the particulate matter standard in 1997. These changes effectively lowered allowable concentrations of these two pollutants. Ambient air measurements show that Wichita is closer to exceeding the new ozone standard but we are currently in attainment with both the ozone and particulate matter standards.

Sources of Pollution

The pollutants in urban air come from many sources. The major contributors are:

  • Mobile sources (automobiles, trucks, buses, and trains)
  • Area sources (smaller sources such as boilers, dry cleaners, and citizen activities)
  • Stationary (industrial), and natural sources (background) are also contributors.
