Environmentall Air Pollution Control Monitoring Program

Ensuring the quality of the air you breathe

You can access air quality monitoring results for Missouri and the Saint Louis County area directly from the online services of the Missouri Department of Natural Resources. Saint Louis County DPH reports monitoring results directly to the State DNR. You'll be querying their database, so use the following paths for the statewide network, the Saint Louis sites, or go straight to a particular site from the list below.
