Ground-level ozone in the Kansas City region is an air quality problem, exceeding federal standards at times, and causing health problems for many citizens. Johnson County, along with Wyandotte County in Kansas; and Jackson, Clay, and Platte Counties in Missouri collectively make up the Kansas City "airshed" that is subject to air pollution regulations set by the Environmental Protection Agency (EPA). All five counties in two states work together along with the Mid-America Regional Council, the Kansas Department of Health and Environment, and the Missouri Department of Natural Resources to monitor and evaluate sources of air pollution and work toward decreasing air pollution.

EPA has set national air quality standards (or limits) for the six air pollutants (also referred to as "criteria" pollutants.) These are lead, sulfur dioxide, particulate matter, carbon monoxide, nitrogen oxides, and ground-level ozone. Kansas City has historically had problems with ozone in the metro area and we are still working to remain within the standard. During the 2007 ozone season (April - October), the metro area air quality has exceeded the federal ozone standards six times.
