If the AQI changes significantly, we will update the Air Quality message line: (907) 343-4899.
Results of recent air monitoring is available here weekday mornings. Updates about air pollution levels in Anchorage can also be obtained by calling 343-4899. This recording is updated before 9AM each weekday. The numbers reported relate measured concentrations of pollutants to health effects that may be experienced at those levels by means of the Environmental Protection Agency (EPA) Air Quality Index.

Air Quality Data for Anchorage
Get the most recent air quality data from stations in Anchorage and Eagle River. Levels given at counting stations (color-coded dots) reflect an 8-hour average concentration at the monitoring site; they are not a snapshot of air quality at current time. The Alaska Dept. of Environmental Conservation maintains this information and can be accessed through the following link. Monitors for the Municipality include "Anchorage" and "Eagle River". Though monitors continuously collect data, reporting of information from sites to the internet can be problematic.
Merrill Field Lead Monitoring Study
The Anchorage Department of Health and Human Services (DHHS) has completed a one-year monitoring study of airborne lead levels at the Merrill Field Airport. Merrill Field was one of 15 airports selected by the EPA for lead monitoring. This monitoring will help determine whether airports serving large numbers of piston aircraft meet new, more stringent air quality standards for airborne lead set by the EPA in 2008. Click here to view the report or an overview of the study can be found on the Merrill Field Airborne Lead Monitoring Fact Sheet.
Anchorage Benzene Monitoring Studies
The Air Quality Program has completed a year-long study of indoor and outdoor benzene levels in Anchorage. Previous studies conducted in Anchorage suggested that levels of benzene in outdoor air and inside homes were higher than those in most of the U.S. An overview of the studies can be found on the Anchorage Benzene Monitoring Studies Fact Sheet.
The full studies can be found at:
Anchorage Outdoor Benzene Study Phase 1
