Ambient Air Monitoring

monitoring equipment

Johnson County is part of a regional air quality monitoring program for Kansas City. There are two current monitoring locations located in Johnson County, one at 8500 Antioch and the other at Heritage Park. The monitors are currently operated and maintained by staff from the Air Quality Program in the Unified Government of Wyandotte County (UGWC). Their monitoring staff have many years of experience and expertise in air quality monitoring and is responsible for operating an extensive ambient air quality monitoring network in Wyandotte and Johnson Counties.

Federal health levels for air quality are set by EPA for the National Ambient Air Quality Standards (NAAQS). The NAAQS is comprised of six criteria pollutants, each one having its own health limit: Ozone (O3), carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), lead (Pb), and sulfur dioxide (SO2). This program monitors the ambient levels of these pollutants except for lead. Lead has largely been removed as a pollutant in most parts of the country as a result of the the use of unleaded gasoline. It is only monitored in local areas where there is a lead source. The monitoring staff also operates a complex weather station as part of the program. The monitoring staff coordinates closely with the Mid America Regional Council and the other state and local agencies in the region to insure that good data is collected and reported.

Gaseous Monitoring Network

The Gaseous Monitoring Network currently consists of four types of analyzers. There are for ozone, carbon monoxide, sulfur dioxide and nitrogen oxides. One ozone analyzer is operated in Johnson County at Heritage Park at 15900 Lackman.

Particulate Monitoring Network

metropolitan towerThe Particulate Monitoring Network currently consists of five types of particulate samplers with eleven monitors total. These monitors sample for various sizes of particulate matter. This includes fine particulate matter which can lodge deep in the lung tissue and some may even get into your bloodstream. At some locations, there may be two identical samplers operating side-by-side. One operates as a regular sampler and one operates as the collocated sampler to provide data verification for the regular sampler. Two fine particulate samplers are located in Johnson County. One sampler operates at the Antioch Justice Center, 8500 Antioch, and one sampler operates at 15900 Lackman, Heritage Park.

All monitors operate on a specified schedule. The filters are recovered and sent to a lab for analysis.
