Local Air Quality
The Southwest Ohio Air Quality Agency monitors air pollutants daily. The results are then released to the public in the daily Air Quality Index (AQI). Levels of six criteria pollutants are monitored to determine the region's air quality as it relates to a series of health-based standards. Pollen and mold counts, air toxics levels, anti-tampering inspections, stack observations/validations and emissions inventory programs are also conducted by the Agency.
