New LANL cleanup documents posted, Pueblo Canyon work plan available

Los Alamos National Laboratory updated its public archives on December 22, 2025, adding several items to the Los Alamos Legacy Cleanup Contract Electronic Public Reading Room. Chief among the additions is the Phase III Investigation Work Plan for the Pueblo Canyon Aggregate Area, made available with a direct PDF link on the EM LA website. The posting continues the laboratory and federal cleanup program practice of providing public access to legacy cleanup documentation.

The electronic public reading room exists to provide transparency and public access to legacy cleanup documents that are required to be posted after April 30, 2018. The LANL electronic public reading room remains available for documents posted prior to that date, preserving continuity for researchers and residents tracking long term cleanup activity. Links to the public reading room and the specific document files are available on the LANL news page announcing the additions.

For Los Alamos County residents, the newly posted work plan is an immediate opportunity to examine the scope of proposed investigations in the Pueblo Canyon Aggregate Area. Investigation work plans typically describe the planned studies, sampling approaches, and objectives that inform any later cleanup decisions. Making these materials public allows residents, local officials, and independent researchers to monitor schedules and assess whether subsequent remediation actions align with community priorities and regulatory standards.

The posting also reinforces obligations around information access that underpin public oversight of legacy cleanup work. Electronic availability reduces barriers to review and can prompt informed civic engagement during future decision points. Residents seeking to review the documents should follow the links provided in the LANL news posting to the Electronic Public Reading Room and the EM LA site.

As cleanup efforts progress, continued timely posting of work plans and supporting records will be essential for community confidence and institutional accountability. Local officials and community groups may use the materials to coordinate questions for project managers and to ensure that environmental planning remains visible to those most affected.
