Hot Springs National Park's air quality reflects the Ouachita Mountain valley position in Arkansas, with vehicle traffic on the surrounding Central Avenue historic bathhouse corridor contributing modest local sources. The Ouachita Mountain topography creates modest enclosure, while the thermal springs' distinctive mineral water vapour contributes unique local aerosols and the park generally maintains moderate to good conditions within the broader Arkansas regional airshed throughout most of the year.
