Air Quality Matters!

RAPCA measures air quality with an extensive network of air quality monitors. Monitor locations are determined using criteria set by U.S.EPA's Office of Air Quality Planning and Standards.

The data from these monitors is used to calculate the Air Quality Index (AQI).  The AQI uses a simple color coded system (Green, Yellow, Orange and Red) to report daily air quality and focuses on health effects you may experience within a few hours or days after breathing polluted air.  

RAPCA issues AQI forecasts each day so if you’re interested in receiving these forecasts, or want to learn more about the AQI, please visit U.S. EPA’s Enviroflash website.  RAPCA’s air quality data is also used to determine whether our air meets U.S. EPA's National Ambient Air Quality Standards (NAAQS).

If you’re interested in learning more about our area’s designation status, please visit Ohio EPA's Attainment Designations page.

Beginning in 2016, RAPCA and Waste Management began a canister sampling project near the Stony Hollow landfill in Dayton.  In May 2017, RAPCA expanded the sampling with a community monitoring project.

* RAPCA was granted permission from U.S. EPA to stop monitoring for lead at Site 8 at the end of 2016.  RAPCA began sampling at this location in late 2011 and since sampling began, lead levels have shown to be less than 10% of the National Ambient Air Quality Standard, therefore eligible for cessation.
