Monitoring Network

The Agency maintains a monitoring network that uses state-of-the-art instruments dedicated to collecting high-quality air quality data. This data determines the compliance status of Southwest Ohio with the National Ambient Air Quality Standards (NAAQS) established by the U.S. EPA. Southwest Ohio is currently in compliance with three of the six of the NAAQS.

Current Local Air Quality Map

To determine the air quality in Southwest Ohio, the Agency maintains monitors in five counties—Butler, Clermont, Clinton, Hamilton, and Warren. There are two types of monitors:

Continuous monitors: operate constantly and measure ozone, sulfur dioxide, carbon monoxide, oxides of nitrogen and inhalable particulates. Fifteen continuous monitors are located in Southwest Ohio.

Intermittent monitors: collect airborne particles at 24-hour intervals from twelve locations in the area. Toxic monitoring data is also collected from intermittent monitors at four locations.
