Contaminated Sites Program

The Native Village of Eklutna (NVE) Tribal Council and US Environmental Protection Agency support the NVE Land and Environment Department to advocate for cleanup of lands near our community.
Of particular interest are contaminated sites and Brownfields near Eklutna Village, especially those that may affect Eklutna lands and people. The NVE Land and Environment Department will track these sites and, where useful, help with and coordinate timely assessment and cleanup efforts.

What is a Brownfield?
What is a Brownfield? Brownfields are generally contaminated sites which could be targeted for cleanup and reuse or redevelopment. According to the EPA, a ‘brownfields site’ is defined as real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant or contaminant. Another Brownfields site qualification is that there is no solvent responsible party.

Examples of potential Brownfields:

  • Old or illegal dumps
  • Petroleum spills
  • Abandoned or idle structures with lead paint, asbestos or other hazardous materials
  • Old fuel storage areas
  • Mine scarred lands

Brownfields Redevelopment Process

  • Site identification and prioritization

Old Matanuska Townsite

This is our best potential Brownfield site.  The documents below detail voluminous contaminants were stockpiled by one site owner, whose heirs do not have the money for assessments or cleanup.  Most of the contamination has been removed, but may have secondarily impacted neighboring lands through groundwater.  Six area land holders may be impacted.  The site is bordered by Rabbit Slough and Wasilla Creek, which sustain salmon fisheries and it supports subsistence resources such as moose.  The lands could be assessed for contaminants, cleaned up if necessary, and reused as conservation mitigation wetlands.

Matanuska River Dump

This is an open debris pile on and in the Matanuska River. The Alaska Railroad initially placed railroad cars at the site in the 1960’s to help stabilize the river bank. After the railroad cars were placed, the site was used as an unpermitted open dump. Trash, including vehicles, household garbage, fuel cans and 55-gallon drums, scrap metal, and other miscellaneous debris were discarded there. The dump has the potential to directly impact the river’s water quality. River channels run through and next to the dump at all times of the year. Visible sheens have been observed in the river. This open dump is within the Drinking Water Protection Area for a minimum of three public water systems. The Matanuska River is designated for all uses, with the most common uses being subsistence and recreation, including fishing and river rafting. The dump is near a hiking trail in a scenic riparian woodland area.
