The Louisville Metro Air Pollution Control District is responsible for ambient air pollution monitoring in Jefferson County, Kentucky. Most of the monitoring is conducted at air monitoring stations or sites. Sites may have just one monitor or multiple monitors depending on the monitoring objective(s). Other sites may have additional support equipment such as meteorological instruments that measure wind speed, wind direction, temperature, precipitation, humidity, and solar radiation.
The number of monitoring sites may vary from year to year and the monitoring network is evaluated annually to determine if changes to the network are needed. Sites may be added if a need is identified or may be discontinued if the monitoring objective has been fulfilled. To insure national consistency in air monitoring data, EPA requires that all sites meet certain criteria and that monitors are operated using approved procedures. To meet these requirements, network plans are developed and submitted to EPA for review and approval. The table below lists the current air monitoring sites operated by APCD.
