The data on this page consists of .csv and .xlsx files with water-level information collected from a pressure transducer within the borehole during pumping conditions for the "stressed" heat-pulse flow measurements. The water-levels were used for drawdown calculations.
The collection of borehole geophysical logs and thermal imaging data was conducted by the U.S. Geological Survey South Atlantic Water Science Center in the vicinity of the Hemphill Road TCE National Priorities List Superfund site near Gastonia, North Carolina, during August 2014 through February 2015. In an 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, surface geological mapping and borehole geophysical log and image data collection, which included the delineation of more than 600 subsurface features (primarily fracture orientations) was conducted in 5 open...
The data on this page consists of .csv files that contain vertical flow measurements within the borehole and the associated depth below land surface. Measurements recorded under both ambient and stressed conditions are contained in each file.

The data on this page contain .pdf files of field sheets that show water level and pumping flow rate during heat-pulse flow meter measurements during stressed conditions.
The data on this page contain .pdf files of thermal images collected at 10 stream sites nearby study area, showing stream surface and bank seepage temperature readings.
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.
