Days with an AQI in 2006 (of 365)

In 2006, EPA reported a daily Air Quality Index (AQI) for Escambia, Alabama on 121 days. 31 of those days (26%) were in the Good range, and the median daily AQI was 57. That median is higher than the typical monitored county in Alabama (median 49 across 19 counties), and higher than the typical monitored U.S. county (44). The main pollutant was fine particles (PM2.5) on 121 days.

EPA did not report an AQI for every day of 2006 here (121 of 365 days). Figures describe monitored days only; seasonal monitoring (for example, ozone measured only in warmer months) can make a county look cleaner or dirtier than a full-year record would.

The most recent year with data for this county is 2007; EPA's files for 2008–2025 contain no row for it, which usually means its monitors stopped reporting.

Years with fewer than 120 monitored days (2000, 2001, 2002, 2004, 2005, 2007…) are shown in the table but left out of comparisons and trend statements.

What this data can and can’t tell you

It is a county-level summary. EPA reports one AQI per day for the county, based on the monitors operating there. Air at a particular street, school or home can differ, especially near roads, industry or wildfire smoke.

It is not a health assessment. The AQI is EPA’s scale for communicating daily air quality. A county’s history can’t tell you what the health risk is for any particular person. For daily conditions and health guidance, see AirNow.

Rules change over time. EPA has revised AQI breakpoints, most recently for fine particles in 2024, so some year-to-year change can reflect the scale rather than the air.
