EXECUTIVE SUMMARY
GEL Geophysics performed geophysical borehole logging services in five, 6-inch diameter
residential wells located at various properties in Arden, North Carolina, and in one, 4-inch diameter
monitoring well located at the Duke Energy Asheville Plant. The field investigations were performed on
May 9-12, 2016, on June 6, 2016, and on June 27, 2016. These investigations were conducted to aid
SynTerra in evaluating potential pathways for groundwater migration through fractured bedrock at the
sites. The geophysical logs consisted of acoustic televiewer, caliper, fluid resistivity, fluid temperature,
single point resistance (SPR), spontaneous potential (SP), and heat pulse flowmeter (HPF). HPF logging
was conducted under ambient conditions for all wells, and under pumping conditions for wells AS-9,
AS-14, AS-20, and MWI8BRL. HPF logging was conducted throughout all the logged intervals.
The logging data was analyzed to determine the location, orientation, and aperture of fractures;
and other features. In addition to these data sets, synthetic caliper logs were calculated from the
acoustic televiewer travel time data to aid in the interpretation. Dip, azimuth (dip direction), and
aperture were calculated for each detected fracture based on the televiewer dataset. HPF data was
analyzed to detect water producing fractures.

1.0 INTRODUCTION
GEL Geophysics performed geophysical borehole logging services in five, 6-inch diameter
residential groundwater wells located in Arden, North Carolina (AS-9, AS-11, AS-13, AS-14, and AS-
20), and in one, 4-inch diameter monitoring well located at the Duke Energy Asheville Plant
(MWI8BRL). The geophysical logs consisted of acoustic televiewer, caliper, fluid resistivity, fluid
temperature, single point resistance (SPR), spontaneous potential (SP), and heat pulse flowmeter
(HPF). The field investigations were performed on May 9-12, 2016, on June 6, 2016, and on June 27,
2016. The logging data was analyzed to determine the location, orientation, and aperture of
fractures; and other features. In addition to these data sets, synthetic caliper logs were calculated
from the acoustic televiewer travel time data to aid in the interpretation.
2.0 EQUIPMENT AND METHODOLOGY
The information below is an overview of the geophysical methodologies used for this
investigation. The intent of this overview is to give the reader a better understanding of each method,
and background information as to what is actually measured, the resolution of the method, and the
limitations imposed by site -specific subsurface conditions.
2.1 Acoustic Televiewer
Acoustic televiewer logging produces a high resolution, magnetically oriented digital image to
map the location, aperture and orientation of intersecting fractures, foliations, and lithologic
contacts. The Acoustic televiewer tool emits a rotating, narrow, acoustic beam that is reflected off
the borehole wall. The travel time and amplitude of the reflected wave are recorded by the tool and
used to create borehole images. Both datasets are useful for identifying the location, aperture and
orientation of fractures. The amplitude of the reflected signal will decrease at the location of
fractures and the travel time will increase. The travel time data can also be used for developing a
high resolution caliper log for a more comprehensive analysis of fractures. Acoustic televiewers can
only be used in fluid filled boreholes. However, the fluid does not have to be optically clear for the
method to work. The acoustic televiewer has a vertical resolution of 2 millimeters.

2.2 3-Arm Caliper
Caliper logging is used to generate a profile of the borehole diameter with depth. The tool
measures the borehole diameter using three spring -loaded arms. Narrow enlargements in the
borehole diameter can, in most cases, be attributed to fractures. Caliper logging can be conducted
above and below the water surface.
2.3 Fluid Temperature
Fluid temperature logging is used to identify where water enters or exits the borehole. In the
absence of fluid flow, a gradual increase on water temperature of approximately VF per 100 feet of
depth is expected. Rapid changes in the fluid temperature indicate water -producing or water -
receiving zones. Little or no temperature gradient indicates intervals of vertical flow.
2.4 Fluid Resistivity
Fluid resistivity logging is used to measure the electrical resistivity of the fluid in the borehole.
Variations in fluid resistivity can be contributed to concentration variations of dissolved solids. These
differences can occur when sources of water have contrasting chemistry and have come from
different transmissive zones. Fluid temperature and resistivity are measured concurrently using the
same logging tool.
2.5 Single Point Resistance (SPR)
Single point resistance logging involves passing an alternate current between a surface
electrode and a probe electrode and measuring the voltage difference created by the current. SPR is
then calculated using Ohm's law. SPR is the sum of cable resistance, and the resistance based on the
composition of the medium, the cross sectional area and length of the path through the medium.
Therefore, the single point resistance log does not provide quantitative data. In general, SPR
increases with increasing grain size and decreases with increasing borehole diameter, fracture
density, and the concentration of dissolved solids in the water. Single -point resistance logs are useful
in the determination of lithology, water quality, and location of fracture zones.

2.6 Spontaneous Potential (SP)
SP logging is conducted to measure naturally occurring voltage differences along a borehole.
The method has been found useful for delineating sandstone/shale layering and other boundaries
between permeable and impermeable beds. The measurements are made with reference to an
electrode at ground level. Therefore, SP logging does not provide quantitative data.
2.7 Heat Pulse Flowmeter (HPF)
HPF logging measures the direction and rate of vertical fluid flow in a borehole by heating up a
small volume of water and monitoring temperature variations as the heated water moves with the
fluid flow in the borehole. Under ambient conditions, differences in hydraulic head between two
transmissive fractures produce vertical flow in the borehole. However, if the hydraulic head is the
same, no flow will occur under ambient conditions. Therefore, HPF logging is also conducted under
low -rate pumping conditions. HPF readings are point readings at the location of fractures. The
location and number of these readings can be determined after analyzing the other geophysical logs
for fractures. HPF can be used for measuring vertical flows between 0.005 gallons per minute (gpm)
and approximately 1.5 gpm.
3.0 FIELD PROCEDURES
All GEL Geophysics activities on -site were supervised by a senior geophysicist. For this
investigation, GEL Geophysics used a Mount Sopris Matrix logging system. Pumping tests during HPF
testing were conducted using a Grundfos Redi-Flow-2 water pump with variable speed control box
and an in -situ Mini -Troll pressure transducer with logging capabilities. HPF logging under pumping
conditions commenced after the borehole water level had stabilized. HPF logging was conducted
throughout the logging intervals under ambient conditions for all wells, and under pumping
conditions for wells AS-9, AS-14, AS-20 and MWI8BRL. Typical spacing between readings was 10-20
feet. More closely spaced readings were then conducted at sections with abrupt changes in flow. A
summary of the configuration of the borehole, pumping rates, and water levels is provided below. All
depth measurements for the residential wells are referenced from the top of casing. The depth
measurements for MWI8BRL are referenced from ground surface. All wells are surface cased and
open hole below the casing.

4.0 DATA PROCESSING AND RESULTS
The logs were analyzed for fractures and other features using WelICAD software, manufactured
by Advanced Logic Technology. The travel time data from the acoustic televiewer log was used to
develop synthetic caliper logs. Fractures were interpreted through a complete data analysis of all
logs. The logs are presented in Appendix 1 and a fracture summary for each well is provided below.
Dip, azimuth (dip direction), and aperture were calculated for each detected fracture. The fracture
data was corrected from apparent to true dip and azimuth using deviation logs included with the
televiewer dataset. The azimuth or dip direction is measured clockwise from magnetic north (Figure
1). Attributes for all identified fractures for the wells are listed in the tables following this section.
Dominating water producing fractures based on flow logging are highlighted and shown in bold and
italics text. Minor water producing fractures based on flow logging are shown in bold. Fracture rose
diagrams are presented on Appendix 2. HPF logs and fracture characteristics are shown on Appendix
3. All depth measurements for the residential wells are referenced from the top of casing. The depth
measurements for MWI8BRL are referenced from ground surface.
