If you burn wood for heat, please consider your neighborhood air by burning smaller hot fires. Well seasoned wood and good air flow will result in almost no visible smoke from your stack and produce maximum heat from your wood.
When the temperatures at night dip below 20 degrees, please plug in your engine block heater. Plugging in can cut CO emissions by 50%. Timers for your block heater are available at the DHHS on 8th and L St.
Pollen season is over. See the links on this page for historical data.
Please consider your neighbors with asthma and heart/ lung ailments by minimizing airborne dust. If you are responsible for a commercial lot, touch bases with your sweeping contractor in advance to ensure they will follow municipal guidelines for dust control.

Remember the use of leaf blowers for dry sweeping is not allowed!
The most current air quality levels available can be accessed online through a link below for "short term air quality data for the Anchorage area". The link immediately below explains AQI values and their health effect significance.
The values given for AQI relate pollutant concentrations to health effects that may be experienced at those levels by means of the Environmental Protection Agency (EPA) Air Quality Index. For further information about the index from EPA click here.
Get the most recent air quality data from stations in Anchorage and Eagle River by means of the Alaska AQI. Levels given use data from recent hours only at each monitoring site. They will differ from the EPA index reported and forecast above because of their short-term nature. The Alaska Dept. of Environmental Conservation maintains this information. Monitors within the Municipality include "Garden" - a site in the Airport Heights neighborhood in north Anchorage; "Laurel" - located on Tudor Road near the intersection with Lake Otis; "Parkgate" - a site on the Old Glenn Hwy. in the business district of Eagle River. Though monitors continuously collect data, reporting of information from sites via the internet may be periodically interrupted.
During periods of smoke intrusion, people with respiratory illness or heart disease, the elderly, children, and pregnant women are advised to avoid exposure to smoke. When in areas of smoke, avoid outdoor activities and physical exertion.

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:
