Structure feature orientations for selected boreholes near GMH Electronics Superfund site, Roxboro, NC (2012-2015)

Metadata Updated: July 6, 2024

The collection of borehole geophysical logs and images and continuous water-level data was conducted by the U.S. Geological Survey South Atlantic Water Science Center in the vicinity of the GMH Electronics Superfund site near Roxboro, North Carolina, during December 2012 through July 2015. The study purpose was part of a continued effort to assist the U.S. Environmental Protection Agency in the development of a conceptual groundwater model for the assessment of current contaminant distribution and future migration of contaminants. Previous work by the U.S. Geological Survey South Atlantic Water Science Center at the site involved similar data collection, in addition to surface geologic mapping and passive diffusion bag sampling within monitoring wells (Chapman and others, 2013). The continued data compilation efforts included the delineation of more than 900 subsurface features (primarily fracture orientations) in 10 open borehole wells. Geophysical logs, borehole imagery, pumping data, and heat-pulse flow measurements were collected and are presented within this data release. The data on this page contain borehole structural feature data measured on the optical and acoustic televiewer logs. Dip direction and dip angle, along with depth of feature and feature type are described within each spreadsheet.
