Exhibit F Environmental Monitoring Locations Figure.pdf

Exhibit F is a site layout map for the Captain Jack Superfund Site located in Ward, Colorado. The document illustrates the geographic locations and features relevant to environmental monitoring activities at this remediation site. Key elements depicted on the map include monitoring well and borehole locations, water quality monitoring system points, surface water sampling locations, historical mine features, and seep locations both before and after valve closure. The map also identifies the Borehole-ERT Array location, surveyed and assumed mine working locations including the Big 5 Tunnel, Niwot Crosscut, and Dew Drop Mine, as well as the approximate boundaries of archaeological sites (Switzerland Trail and Camp Francis). Access roads and the extent of seep survey areas are marked, with specific elevation ranges noted (8,944-9,144 feet). A critical operational restriction is documented: no vehicular traffic is permitted within the Camp Francis Archaeological Site except in emergencies, as noted in the November 12, 2020 documentation.

This exhibit serves as a technical reference document for site characterization and environmental monitoring activities associated with the Captain Jack Superfund Site remediation project. The map provides essential spatial information for contractors and environmental professionals conducting field work, sampling, and monitoring activities. No pricing information, contract terms, bidder requirements, or funding details are contained within this exhibit, as it functions solely as a reference document illustrating site-specific locations and features necessary for project execution.
