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
