Brownfields are described as a "real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presences of a hazardous substance, pollutant or contaminant". The most common type of brownfield sites in Alaska are petroleum contamination, old or illegal dumps, mine-scarred land, structures containing lead paint, asbestos, PCBs, hazardous materials, or old fuel storage areas.  

In 2010, the United States Environmental Protection Agency (USEPA) awarded Alaska Native Tribal Health Consortium with the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), Section 128 (a).  This goal of the funding is to ensure that tribal response programs include, or are taking reasonable steps to include the following four elements into their new or existing environmental programs:

1.Timely survey and inventory of brownfields sites

2. Oversight and enforcement authorities or other mechanisms and resources to ensure that a response action will protect human health and the environment.

3. Mechanisms and resources to provide meaningful oppotunities for public participation.

4. Mechanisms for approval of a cleanup plan and verification and certification that cleanup is complete.
