This is a geological cross-section diagram depicting subsurface stratigraphy and borehole construction details. The diagram shows a vertical geological profile with multiple sedimentary layers including limestone, sandstone, shale, and white/light-colored deposits extending from approximately 1,890 feet below surface level to 380 feet above surface level. The illustration indicates various geological levels marked with elevation measurements in feet (ranging from approximately -1,062 to +174 feet). A plug and seal installation, dated circa 2002, is shown at approximately the 380-foot level near the top of the borehole. The diagram includes a detailed legend and notes identifying borehole annular sealed records, construction information, and well-related specifications on the left side. The cross-section uses hatching patterns to differentiate between different soil and rock types and their stratigraphic relationships. This appears to be engineering documentation related to well construction, environmental site characterization, or geotechnical investigation rather than a federal contract solicitation document.
