Arkansas benefits from low population density and relatively limited heavy industry. The Ozarks region has some of the cleanest air in the South, while the Mississippi Delta area has slightly higher pollution from agricultural activity.
ADEQ (Arkansas Dept. of Energy and Environment) oversees air quality. The state has relatively lenient regulations compared to neighboring states.
No current nonattainment areas. Arkansas generally meets all federal air quality standards.
