The Tribal Superfund Working Group (TSFWG) is a network of Tribal professionals, other experts, and government employees that are engaged in work with Superfund sites, Federal Facilities and other sites of special concern. These individuals work on protecting Tribal lands, water, and community health and have become part of this group either by self-subscribing, because of their past work on Superfund issues, or because Superfund is their primary area of work or interest.

January 2024: Climate Vulnerability Assessments at Sites on the National Priorities List

In this quarterly meeting of the Tribal Superfund Working Group, we were joined by Carlos Pachon, from the US EPA’s Office of Superfund Remediation and Technology Innovation (OSRTI). Carlos presented a summary of lessons learned in conducting climate vulnerability assessments (CVAs) at sites on the National Priorities List (NPL). His presentation covered:
  • The underlying authorities to consider climate change at NPL sites
  • Key questions addressed through the climate vulnerability assessment process
  • Tools and data sources used to develop climate projections
  • Recurring climate vulnerabilities that could affect remedy protectiveness
  • The associated adaptation measures needed to increase remedy resilience to climate impacts
  • He also provided a few examples of sites with Native American interest where such an assessment has been done and/or climate adaptation measures have been implemented.

June 2023: The Navajo Nation AUM Portal and Tribal Data

In this quarterly meeting of the Tribal Superfund Working Group we were joined by staff from the Navajo Nation and the EPA. They discussed a collaborative project they’ve worked on called the Navajo Nation Abandoned Uranium Mine Data Portal. They addressed the issue of data sovereignty and integrity, and highlighted their work on creating this web-based portal over the last several years. The portal includes an internal web viewer for visualization of data collected, access to SharePoint libraries containing relevant data and metadata, up-to-date staff contacts from both government agencies, and a help and support page complete with training videos. The Navajo AUM Data Portal ensures that data collected in the course of Superfund work on Navajo Nation are secure and accessible to both EPA and Navajo Nation. Today, the Navajo AUM Data Portal is used to review sites, work plans, historical site information, and generate mobile applications for use in field reconnaissance.

Critical Minerals Presentation and Discussion thumbnail

March 2023: Critical Minerals Presentation and Discussion

This presentation was recorded in March 2023 as part of the Tribal Superfund Working Group meetings. Critical minerals provide the building blocks for many modern technologies, including batteries for green technologies and electric vehicles. The Biden-Harris Administration is prioritizing domestic production of key critical minerals while balancing concerns from communities about renewed mining efforts and impacts. EPA and USGS representatives share the latest on the federal government’s work to increase sustainable mining of critical minerals as well as efforts to reprocess mining waste to collect critical minerals at existing mines.
