This is a technical diagram depicting Well Screen Number 1 at the Bureau of Reclamation's Leadville Facility. The diagram illustrates a vertical cross-section of a well installation showing ground elevation at the top, with a 20-inch casing extending to the surface. Water elevation is marked at 80 feet below ground level. The well screen configuration consists of three main components: an approximately 6-foot tall screen positioned at 120 feet depth, a coupler connecting to a second approximately 6-foot tall screen, another coupler, and an approximately 2-foot well screen at the bottom, with the entire screen assembly terminating at 139 feet depth. The well screens are constructed of 1/4-inch round stock vertical bars with 1/4-inch round stock rings welded to the vertical bars in a grid-like pattern. Depth measurements are taken from the top of the casing. This technical specification document provides engineering details necessary for understanding the subsurface well structure and screen placement at the facility.
