Altitude of selected beds and inferred faults in boreholes as identified from geophysical logs at Valmont TCE Site, Luzerne County, Pennsylvania

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-08-11T00:00:00Z
This dataset contains altitudes of selected beds and inferred faults in boreholes within an area of interest determined by the U.S. Environmental Protection Agency (EPA) at the Valmont TCE Superfund site in Luzerne County, Pennsylvania. The selected beds correspond to sections of borehole geophysical logs with elevated natural gamma activity as described in the U.S. Geological Survey (USGS) Open-File Report 2021–1093 (Senior and others, 2021). Geophysical logs were correlated on multiple cross sections in this USGS report, which showed these geologic features and inferred faults in the subsurface. Additionally, thin coal or coaly beds were identified from borehole density logs (Senior and others, 2021). The altitudes of these geologic features where they intersect boreholes as displayed on the cross sections are provided here, as well as locational information for each borehole. Naming conventions used for beds are provided in this dataset only and are not present in Senior and others (2021), thus cross sections from Senior and others (2021) with added labels for bed identifiers are also provided.
