Section_J_Attachment_6b_2022_CAVE_Geophysical_Investigative_Report.pdf

The document appears to be a geophysical investigative report (Section J Attachment 6b) related to a National Park Service project involving the Cave 332397 Main Distribution System replacement. The report is part of a solicitation (No. 140P2026R0007) by the Department of the Interior National Park Service, focused on comprehensively replacing underground distribution infrastructure. The primary project goal is to protect the caverns by addressing potential pipe leakage through a complete system replacement, rather than incremental repairs. The investigative report likely contains technical details about the current underground infrastructure, potential geological challenges, and preliminary findings to support the planned infrastructure upgrade.
