FINAL REMEDIAL INVESTIGATION REPORT

EXECUTIVE SUMMARY
The Remedial Investigation (RI) provided data on the physical
setting and conditions at the CFO/SHELBY facility, as well as
geochemical data on the quality of the soil, sediment and surface
water onsite; and on the general ground-water quality on site and
at nearby offsite locations. These studies documented the
presence of organic and inorganic constituents in soil and water.
Geohydrology
The subsurface conditions are typical of the geologic setting,
where a mantle of residual soil overlies gneiss or schist bedrock
except where altered by man, or occasionally, by alluvial
processes. Residual soils occur at the ground surface except
where overlain by engineered fill associated with the plant
construction, a demolition/rubble landfill, or disposal fill of
wastes in burn pits and the shallow GRU sludge trenches.
Ground-water monitor wells have been installed in the soil and
shallow bedrock. Interpretation of the water table elevation data
indicates that the site ground water occurs under unconfined or
water table conditions in most instances, and flow directions
approximately parallel surface topography. Ground-water
discharge probably occurs to the surface streams which receive
their baseflow from ground-water discharge from the banks or
through the stream bottoms.
Geochemistry
Test pits in the demolition fill area provided samples of
soil degraded with synthetic organic compounds. Present data
suggest that the southern portions near the disposal fill have
higher contaminant concentrations than other portions of the
demolition fill.
The western terrace of the lawn area associated with the
wastewater treatment plant contains the GRU disposal pits and the
burn pits used during the early plant operations. This area is
thought to be the primary contaminant source area. Some other
areas in the main plant and ancillary to the wastewater treatment
plant contain organic compounds similar t~ those in the disposal

fill area, but at generally lower concentrations. Analyses of
stream sediments showed generally similar compound classes to
those present in the fill areas, but at lower concentrations.
The higher concentrations of compounds are generally found on the
perimeter streams to the north of the plant.
Phases II and IIA sampling were given primary consideration in
evaluating the ground-water quality. Wells sampled during these
events were located generally around the perimeter of the site,
and the samples represent water quality entering and exiting the
site. Analyses of these samples showed varying results from the
two sampling periods, with variations occurring in both the
compounds identified and the concentrations of a particular
compound in one well on separate dates. Thus, mappable trends in
ground-water quality were not identified. However, the data do
show that compounds similar to those identified in the probable
source area were detected in the ground water.
The ground-water quality was measured at 19 offsite locations
during the Phase I and IA ground-water sampling. These data also
showed an inconsistency in detected compounds and measured
concentrations between sampling events. No definable plume
associated with the CFO/SHELBY facility was identified. Testing
indicated organic constituents have not spread from the
contaminated area through the ground water beyond the property
boundaries. Analysis of samples from the downgradient wells
nearest the site (Stein and Lambert) did not detect organic
Hazardous Substance List compounds in the most recent sampling
event. James Elliott's well further downgradient has
consistently shown low levels of trichloroethene (TCE). This
compound was detected at a similar concentration in monitor well
HH constructed near the Elliott well, but there is no traceable
plume which would relate the presence of TCE to the plant
facility.

surface water samples primarily showed compounds

Recommendations
Based on evaluation of the available data, the RI recommends that
the Feasibility Study be performed to evaluate the risks
associated with the site, identify remedial alternatives and
select a preferred alternative for site remediation.

application would not be made, as it was no longer required. The
State agency determined to deny a permit for continuing operation
of a hazardous waste management facility and to terminate interim
status under Part A. The notice was dated 17 September 1984 and
became effective 30 September 1984. The stated conditions were

The Project Operations Plan, appended to the Consent Order with
the Work Plan, tacitly accepts these objectives in describing the I
implementation of the Work Plan. These objectives are addressed
in the presentation of the data, analyses and conclusions of the
RI in the following sections of the report.
1.4 Site History and Background
The CFO/SHELBY facility is located east of State Highway 198,
south of the Town of Shelby and north of the Town of Earl, North
Carolina. The facility first began operations around 1960, and
has continued production and processing of polymer chips and
blending of
texturizing
1982. Each
polymer fabric since that time. A process line for
polyester fiber has been out of operation since
of these processes involves organic and inorganic
chemical feedstock and product.
The plant site is shown on the reproduced portion of the USGS
Blacksburg North 7 1/2' Quadrangle (Figure 1-1). The main plant
structures are located along the crest and east slope of a
north-trending ridge between dissecting tributaries of Buffalo
Creek. Surface drainage is to the east, toward Buffalo Creek,
with eventual discharge to Broad River. Buffalo Creek provides

the water used in the plant processes and for other consumption.
Non-contact and treated waste-stream waters are ·returned to the
Creek.
Land use prior to construction at the site was dominantly forest
and agriculture. Present land use within a half-mile of the
plant site retains this pattern with the exception of scattered
residential, municipal and commercial development, to the
southeast, southwest and northwest.
The plant facilities consist of the plant producation area,
wastewater treatment area, waste disposal areas, and the
recreational and tree farm area to the south of the main plant.
The USGS topographic map indicates that the developed areas of
the plant had post-construction elevations within a range of 780
to 860 feet above mean sea level (ft MSL) in the areas shown on
Figure 1-1. A more recently surveyed map of the plant and
grounds (aerial photography February 1985), showing present
cultural modifications (Figure 1-2), indicates that the plant
production area lies between 830 and 870 ft MSL; the wastewater
treatment area, between 780 and 830; the landfarm, between 800
and 860; the recreation area, between 800 and 820; and the
.forested area east of the watertreatment area descending in
moderately rolling terrain between 780 and 720. The highest

topographic perimeter of the site lies along the west side, along
Highway 198, between elevations 840 and 870. Thus, the
operations areas of the site were developed on the highest
available ground, with the present topography dropping moderately
to the north and south, and less steeply to the east. The
majority of the land surface reflects cultural modification by
construction, and by cutting and filling. The original soil
profile has probably been either truncated or covered across much
of the site, and was never conclusively identified as undisturbed
during the field investigations of the RI. The plant production
area is predominantly covered with buildings and paved or
gravelled areas. However, to the east, toward the wastewater
treatment area, the site becomes more open with the majority of
the land covered by impoundments, with grass and access roads in
between.

To the north, the landfarm is now overgrown with coarse
The recreation area and tree farm to the south have no
facilities related to the plant processes.
The recreation area comprises primarily a small reservoir, its
outlet creek and the tree farm adjacent to the south. There is
no evidence or description of disposal of waste in this area.
Many of the plant activities potentially affecting the quality of
runoff water or ground-water infiltration are located in the
plant production area. Surface drainage in some of the paved and

an area where sludge from the glycol recovery unit (GRU) had been
buried during the early years of operation.
West of the GRU disposal area is an abandoned drum storage area.
This was also used during the early operation of the plant.
Materials stored in this area included off-specification process
chemicals, probably of the same type presently used. The drums
were subsequently removed and properly disposed of by Rollins
Environmental Services, Inc., when storage practices ceased in
the mid-1970's. The disposal compatabilitiy tests by Rollins
were not transmitted to CFO/SHELBY. However, if warranted, this
information will be obtained and reviewed for the FS. This area
was subsequently covered by construction and the location was not
precisely recorded.
To the north of the wastewater treatment plant area are various
areas of buried waste. Reportedly, these areas did not receive
liquid or easily dissolved solids. This somewhat inert material
included polymer and yarn waste, as well as demolition and
excavation spoil. Other areas of disposal, of both general and
chemical waste, have been reported, but have not been precisely
located on photographs or drawings.

directions of flow of ground water beneath the site. In the
course of the study, a number of test borings were drilled in
specified areas around the site and converted to monitor wells
for long-term observation of the ground-water environment. These
wells were also subsequently used in the current RI. The
investigative work of this study comprised installation of 24
monitor wells (Appendices I and J) at 18 stations across the site
and performance of field and laboratory tests on the physical and
hydrologic properties of the subsurface materials.

The drilling and sampling techniques in both phases conformed to
ASTM D-1586 for standard penetration tests and to D-1587 for
undisturbed sampling.
S&ME supplemented the data from the exploratory drilling with a
reconnaissance survey of local geologic conditions. Available
information from the drilling and the reconnaissance was used in
evaluating the subsurface geology, in developing a stratigraphic
profile of the shallow subsurface and in establishing certain
geohydrologic parameters and conditions.
The wells with prefaces A through D, F through K, and M through T
correspond to the stations shown on Figure 1-5. The wells
scheduled for stations E and L were deleted from the sequence
following evaluation of the geologic and chemical results of the
first phase, which indicated that wells at these stations would
be redundant. The suffix numbers at each station correspond
approximately to the bottom of the screened interval below land
surface. Differing suffixes indicate that more than one well had
been drilled and installed at that station at segregated and
separated interception levels in the subsurface.
During this investigation, two 6-inch diameter wells were located
that had apparently been abandoned prior to the start of the
investigation. The wells may have penetrated to rock for some

purpose, but presently appear to be grouted to the surface. The
procedures used during this field investigation acted to minimize
cross-contamination between drilling and sampling stations.
These procedures were generally similar to those used during the
RI field work.
1.5.2 S&ME 1983
In the late summer of 1983, S&ME performed a geophysical survey
of selected areas of the site using an electromagnetic induction
(terrain conductivity) device. This is a surface geophysical
method, contrasted to aerial methods, of characterizing the
subsurface of an area by its response to an imposed
electromagnetic field. In effect, this method indicates the
relative ability of subsurface materials to conduct an electric
current. Determination of the actual physical types of these
materials and their associated properties (other than gross
conductance) depends on direct inspection and chemical analysis.
However, certain materials associated with contamination sources
and outfalls (such as tanks, drums, pipes, electrolytic
solutions, and so forth) can be characterized by this method.
The objective of this study was to attempt
indications of contamination in reference
conductivity in the ground water and the subsurface.

The general areas investigated by this study included the open
fields east and west of the e~ergency spill ponds and No. 1
I
polishing pond, the open fields noith of the wastewater treatment
'
area, and the demolition landfill lfarther north of the treatment
area (Figure 1-6). More complete sampling descriptions are
presented in the report.
Area 1 comprised the open field north of the wastewater treatment
facility and west of the emergency spill ponds. The most
conspicuous trend noted from the plotted conductivity values was
I
a strongly defined north/south Iineation near the west side of
the survey area. This lineation cqrresponded to the western edge
of the aeration basin and extend~d northward across most of the
survey area, broadening in the northern section. This east/west
broadening, in the vicinity 1of the K-wells, correlated
approximately with the described: location of the GRU sludge
'
disposal pit. There was no reference to a buried pipeline along
the alignment of this lineatiori, although the conductivity
'
indications were of buried metalliq objects. Thus, the lineation
south of the GRU pond was interpreted to be a pit containing
metallic disposal debris.
' Area 2 lay ' . . to the east of No. 1 polishing pond, adjacent to the
' pond . About 25% of this area apreared to have been unaffected;
the remaining 75%, in the northern'part of the field, showed some

effect of plant or disposal operations. The elevated values
generally observed appeared to be related to previous spray
application of wastewater, with some contribution probable from
the adjacent, liquid-filled polishing ponds or cultural features.
Area 3 included the demolition landfill north and west of the
wastewater treatment area. Data indicated the probable presence
of metallic objects within the landfill.
The remainder of the data were collected around the perimeter of
the wastewater treatment area, and in the area extending to the
southeast corner of the property, along and generally east of the
water intake and discharge pipelines to Buffalo Creek. No
obvious trends were noted except in the area just east of monitor
well T-17. This trend probably indicated the general alignment
of the pipelines or an outfall of effluent from a leaking
pipeline.
In general, the data indicated that most of the area to the west
of the emergency spill ponds had been affected by plant and waste
handling operations, with the southern area to the east of the
No. 1 polishing pond generally representing unaffected background
conditions. The recommendations of this report were reviewed and
subsequently satisfied by the field work for the RI, which
explored the anomalous areas in more detail.

CDM reviewed the available documents and presented a summary and
an initial evaluation of the site; followed by an estimate of the
type and sources of data required to complete the RI/FS. The
background information generally agrees with the presentation in
the section above. Other general information agrees with the
published S&ME reports or other available documents and does not
differ significantly from the information presented in this RI.
The report indicates that not all of the disposal areas on the
site are potential sources for the alteration of ground-water
quality indicated by the chemical analyses cited. The sources
most likely for this alteration appear to be the GRU sludge
burial area, the former drum storage area and the emergency spill
ponds. The other disposal areas are considered having a low to
moderate potential for contaminant distribution include: the
sludge land application area (landfarm); the polymer and fiber
landfill; the buried burn pits; various ethylene glycol/methanol
spill sites; the chemical
landfill; and the various

published a Fact Sheet to provide
for a public meeting on the pending
field program at the CFO/SHELBY site. The Fact Sheet summarized
the history of operations at the site, the current status of the
RI and future actions available or being contemplated.
Site History: The EPA description of the site history paralleled
closely the description in Section 1.4. The EPA mentioned the
major chemicals involved as dimethyl terephthalate and ethylene
glycol, associated with inorganic titanium oxide and antimony.
Remedial Investigation: The EPA presented the objective of the
RI: to define the extent of contamination, to expand and
supplement the available data, and to identify the sources of
contamination and the transport mechanisms involved in the
distribution of contamination from those sources. The ultimate
accomplishment of the RI would be to provide the data required
for formulation and consideration of remedial measures and for
selection of the remedial action program. The EPA expanded on
these general objectives of all Ris in forming the specific
objectives for the Shelby site:
o Determine whether the site poses a public health hazard
or environmental problem.

efficient alternatives for the remedial action. No schedule or
content for the FS was specified.
Current Status: The major events relevant to the intent of the
Public Meeting were preparation of the Forward Planning Study
{COM 1985), and preparation of the S&ME Draft Work Plan. At the
time, the scheduled start of the RI was October 1985.
Future Plans: The EPA anticipated approval of the FS during Fall
of 1987, with a Public Meeting following for comment. The final
document of the RI/FS would be the publication by the EPA of a
Record of Decision (ROD) presenting and explaining the remedial
action selected for the site.

dates. In general, although the photographs clearly showed
various features associated with disposal of chemical waste,
there was no surface expression, such as staining or vegetation
stress, of distribution of those wastes beyond the containment
structures of those features.
Land Use: The false-color photograph for the land use analysis
was taken on 21 May 1981. This analysis covered a radius of
about 1.2 miles around the site. The site was described as being
surrounded primarily by a mixed forest of deciduous and
coniferous trees, cropland and pasture, and limited residential
areas. The recreation lake was noted as being the nearest major
body of surface water to the west of the site. Only one, small
commercial lot was noted adjacent to and west of the site, with
neither commercial nor residential areas adjacent to the north,

as being heavy industrial with associated utilities. There were
notations of other uses, particularly institutional, educational
and rangeland, within the reference circle. None were adjacent
to the site.
(Note: In the descriptions following, features are discussed
with the first photograph in which they are found; subsequently,
they are not mentioned unless there is a significant change in
that feature. Only features associated with disposal practices
appear in the following extracts.) The names associated with the
particular features were taken from information supplied by CFO.
18 December 1960: The photograph indicated that three ditches
drained to the northeast from the large operations building. A
north/south trending pit had been excavated about 270 feet west
of the west side of the present emergency spill ponds. Another
pit had been excavated in the north corner of the plant
production area. There were several areas of mounded material of
undefined association.
12 February 1968: The pit, three ditches and open storage area
noted previously were no longer apparent. Some staining of
ground was noted in the main plant area. The pit on the west

impoundments were noted, along with various channels dissecting
the area. Various locations of undescribed mounded material were
noted. The recreation lake was visible.
11 March 1971: Drum storage remained visible in the eastern part
of the plant production area. A small, dry impoundment had been
excavated near the middle of the east side of the plant
production area. Various drums and debris were noted along the
southern edge of the plant production area. Another impoundment
had been constructed in the southeast corner of the plant
production area. The pit noted in the 1968 photograph was still
present and may have contained liquids; objects that appeared to
be drums were stacked on the south side of the pit. Another
clarifier had been added. Two impoundments in the north of the
treatment area had been filled. Various locations of debris and
mounded material were noted.
1 May 1979: Two liquid-filled lagoons were found to the north
and south of the existing lagoons. The present emergency spill
lagoons had been constructed from one of the existing lagoons.

includes an indication of the type of information expected from
each technique. (NOTE: Section 10.0 contains working
definitions of some technical terms.)
2.1 Topographic Analysis
The topographic analysis consisted of examination of aerial
photographs over an historical period and inspection of
topographic maps available from published sources and prepared
for CFO (Figure 1-2; Plate I). These provided indications of the
locations and probable apparent influences of past and present
disposal practices at the site, particularly around the covered
area within the wastewater treatment facility. As described in
Section 1.5.5, the EPA/EPIC analysis, various locations had been
used for storage or disposal of wastes, with some of the
locations having been reclaimed. Analysis of other photographs
by S&ME supports this indication.

consideration of the topographic analysis, the more detailed
methods were employed.
2.2 Geologic Mapping and Reconnaissance
While the direct exploration and sampling techniques discussed in
the following sections provided detailed information at a single
point within the study site, the broader examination of the site
as a whole provided a general framework in which to place that
information. The development of this framework consisted of
geologic mapping of the rock exposures on and near the site, and
examination of the surface topography. These activities were
performed on a reconnaissance basis and in a less detailed manner
than a rigorous description would require, but are adequate for
the RI. This infomation was compared to the regional map (Figure
4-5) •
The objectives of the mapping and reconnaissance were to develop
an appreciation of the patterns of flow-of surface water, of the
indications on the surface of ground-water flow, of the controls
on either and of the surficial coverage of fill and waste. In
particular,
the pattern

where rock exposure was encountered in streambeds,

regional and local correlation. The pattern of jointing and
fracturing, and the development of secondary mineralization,
indicated the prob.able control of the rock on the movement of the
shallow ground water. Additionally, the depth to which the
streams had incised the overburden indicated the probable
relation of the streams to the discharge of shallow ground water
and their influence as ground-water divides. Overall, the
mapping and reconnaissance were designed to provide indications
of the flow of surface and ground waters, and the potential paths
for the distribution of waste from the disposal areas noted.
2.3 Test Pit Excavation
Exploratory excavation exposed a narrow pit extending to
generally less than 10 feet below land surface. The side of the
pit provided an exposure of the profile of the shallow subsurface

The objectives of the exploratory excavation were to examine the
profile of the fill cover, to locate at least some of the buried
disposal sites, to obtain samples for chemical analysis from
precisely described strata in the profile for correlation, to
indicate the presence of ground water or the controls on vertical
percolation of water and to provide indications and descriptions
of the patterns of waste distribution in the shallow subsurface.
The locations chosen for excavation followed the criteria
discussed in the Work Plan. Forty-six stations (Figures 2-2A and
2-2B) were examined during this program.
2.4 Exploratory Boring Operations
The program of exploratory boring proceeded generally according
to the Work Plan. Eleven locations were selected for monitor
well construction, and the bedrock was cored at eight of these
locations. In addition, fourteen locations were selected for
test drilling and sampling and were subsequently grouted.
Sampling for analytical purposes was performed with
decontaminated sampling equipment, allowing the samples to be
preserved for chemical analysis in a manner similar to those from
the exploratory excavation.
FINAL REMEDIAL INVESTIGATION REPORT
CFO/SHELBY, NC FACILITY
DOCUMENT NO. 85-0SOA-0056 REV.1-0587
PAGE 2-8
The objectives of the boring program were to provide descriptions
of the overburden below the depth available to the excavation
program, to discover the depth to rock at selected stations, to
provide information on the vertical and horizontal distribution
of contamination in the subsurface, to provide a stratigraphic
escription of the shallow subsurface and to provide for
installation of wells to monitor the ground-water environment
over a longer term.
2.5 Monitor Well Installation
Twenty-one monitor wells were installed at the 11 stations
(Figure 1-5; Plate II). The wells are:
D-27.5 AA-54 FF-34.5
D-56.2 BB-18.5 FF-62.4

T-58.5 EE-58 HH-48
AA-41 FF-23.6 HH-77.4
The designation system continues the notation described in
Section 1. 5. 1.
The objectives of the monitor well construction were to provide

to provide information in background areas, within
areas, in areas adjacent to the downgradient side of the
areas, and in areas farther removed from the probable
areas of disposal.
Exploration of the vertical hydraulic or geochemical variation in
the ground water was through construction of five types of
monitor wells as shown schematically on Figure 2-3. The types
are phreatic wells; shallow, deep and intermediate overburden
wells; and rock wells. The distribution of the wells was based
on existing data, and not all types were installed at each
location.
The phreatic wells were designed to intercept the surface of the
water table. Examination of this zone would indicate the
response of the ground-water environment to climatic influences
such as precipitation or drought. The shallow phreatic layer is
the most sensitive zone of the ground water to short-term
influences, including contamination from near-surface sources.

The sequence of overburden wells provided information from the
upper, middle and lower thirds of the overburden, with the
shallow, intermediate and deep monitors, respectively. The
shallow monitor intercepted a level lower than that of the
phreatic well, while the deep monitor intercepted the layer
immediately above the top of the rock. The overburden wells were
selected to provide information on the general patterns of
long-term flow and distribution of ground water and contaminant
transport. The deep monitor was installed to provide indications
of the relation of the overburden and the rock in the flow of
ground water.
The rock wells monitored the upper 25 feet of the bedrock. This
layer was considered to be the most likely to respond to the
presence and movement of ground water in the overburden and to
receive contaminants from the upper layers. Comparison of the

In general, the comparison of relative heads in the wells (the ·•

water from the shallower layers to the deeper layers. Thus, a
downward head in a contaminated layer could lead to a more
extensive vertical distribution of contaminants.
2.6 Chemical Survey by Atmospheric Monitors
While working near the excavations and monitor wells, S&ME
personnel monitored organic vapors with an organic vapor analyzer
(OVA), a photoionization meter (HNu) and an explosimeter. This
program was designed only for the protection of the personnel and
was not intended to provide an indication on the distribution or
severity of contamination across the site. It is, therefore,
neglected in such discussions.
2.7 Chemical Sampling and Analysis
The basis for determination of presence and distribution of
contamination is solely the result _of chemical analysis of ground
or surface waters, or the subsurface materials. S&ME pursued a
sampling program to characterize the vertical and horizontal
environment related to the disposal sites. The samples were
obtained by an appropriate technique from the overburden, the
ground water and the surface water (Figures 1-5, 2-2A, 2-2B and
2-4) . The samples were then delivered to Davis & Floyd, Inc.'s,
analytical laboratory for detailed analysis. The suites of
FINAL REMEDIAL INVESTIGATION REPORT

DOCUMENT NO. 85-050A-0056 REV.1-0587

parameters for these types of analyses are listed in Appendix F.
Sampling protocols are presented in Appendix G.
2.8 Surface Water System
The surface waters of greatest immediate concern to the
investigation are the streams in the eastern hemisphere of the
study area. These streams appeared to cut completely through the
overburden to the top of the rock, having frequent exposures of
rock along their sides and only normal bedload material as the
unconsolidated sediment. The general indications were that the
streams immediately adjacent to the site to the northeast, east
and southeast would intercept the majority of discharge of ground
water from the site. Thus, they would become the receptors of
contaminants entrained in the ground water.
I
I
I
I
I
I
I

S&ME designed a program to characterize the streams by examining I
the relation of the streams to the ground water, by measuring the
flow of the streams at low and high stages at six stations and
sampling the streams for chemical analysis in each of these ,'I
events, and by sampling 23 other stream stations during the
initial survey. All stations are shown on Figure 2-4, with
stations 016, 021, 025, 028, 030 and 031 as the weir locations
where flow was measured.

2.9 Ground-Water System
FINAL REMEDIAL INVESTIGATION REPORT
CFO/SHELBY, NC FACILITY
DOCUMENT NO. 85-050A-0056 REV.1-0587
PAGE 2-21
The ground waters of a site typically represent the part of the
environment initially most sensitive to an uncontrolled release
of hazardous materials. The ground water serves as the mechanism
for distributing contamination to areas remote from the primary
sources of contamination. These are the areas likely to contain
populations or conditions that may be adversely affected, in
varying degrees, by the contaminants.
S&ME designed the ground-water assessment program to examine the
various layers of the subsurface in which water may be found.
The layers were described in Section 2.5, and the monitor well
locations are shown on Figure 1-5. Additionally, 19 commercial
and residential potable water wells were sampled from selected
locations around the site's periphery. The offsite well
locations are shown on Figure 2-5.
The objective of the ground-water assessment program was to
derive appropriate data from which calculations could be made to
indicate the flow and chemical quality of the site's ground-water
regime.

The site is located in the Inner Piedmont physiographic province
of the southern Appalachians. In North Carolina, the Inner
Piedmont is a linear zone approximately 50 miles wide and bounded
by the Chauga Belt/Brevard Fault zone to the northwest and the
Kings Mountain Belt to the southeast. In a cursory view, the

but have locally inconsistent orientations. Draws and streams
dissect the ridges along patterns strongly associated with
conjugate structural trends, and are broadly consistent with a
northwest/southeast orientation. The.major surface water systems
generally· parallel the northeast/southwest trend of the ridges.
These mid-sized streams are fed from smaller draws and originate
as springs. The closest mid-sized stream to the site is Buffalo
Creek, which flows to the southwest and joins the larger Broad
River flowing to the southeast. These streams are the receptors
for overland flow and ground-water discharge from the site.
The general land use of the region retains a strongly
agricultural and forest/range character. Local areas have been
developed for urban, residential and industrial use. The
immediate vicinity of-the site retains a rural setting despite
the site's heavy industrial use.
3.2 Climate
The closest meterologic station to the site recording temperature
and precipitation data lies about 2 miles north-northwest of
Shelby, North Carolina. The closest station recording wind data
over an extended term is located in Charlotte, North Carolina.

storm events, is from the southwest during the summer and from
the west during the winter.
3.3 Geology
The· discussion
includes the
of the general geology in the region of the site
geologic units, regolith, soil types and the
genetic relations among these.
3.3.1 Geologic Units
Geologic units mapped in Cleveland County, around the site,
include a variety of schists and gneisses typical of the Inner
Piedmont, two quartz monzonites, the Toluca and Cherryville, and
a belt of pegmatites {Horton and Butler, 1981). The schists,
gneisses and Toluca Quartz Monzonite have been identifed in the
vicinity of the site.
I

The Toluca Quartz Monzonite is the only geologic unit in the
vicinity of the site having a formal name, the schists and
gneisses divided and mapped only by type (Overstreet, Yates and
Griffitts, 1963). Horton and Butler (1981) did not distinguish

Overstreet, Yates and Griffitts (1963) report that saprolite
thickness in the Inner Piedmont is typically from 25 to 40 feet,
attaining a reported maximum thickness of 185 feet. Throughout
the Piedmont, saprolite is commonly of greatest thickness on the
upper slopes of ridges and of least thickness in stream valleys.

I agricultural land, but was never specifically identified with a
particular soil series. However, surrounding land was identified I
by soil type as being either Seneca sandy loam, Cecil clay loam,
Cecil sandy loam or Appling sandy loam, and by slope and tendency
to erode.
The series most commonly bordering the site and most probably
representative of formerly native soils of the site are the two
Cecil sequences. These vary in texture from clay to silt to
sand, with fine sandy silt dominating. The soils are well
drained; however, the permeabilities are in the range of 0.6 to
6.0 in/hr (4.2 X 10-4 cm/sec or 1. 2 ft/d, to 4.2 X 10-3
cm/sec or 12 ft/d), diminishing downward, indicating that the
majority of this drainage is in the form of overland flow. Soil
reactivity, or pH, ranges from 4.5 to 6.0. Slope of the soil
surface is variable from level to steep. Typical horizons
include a surficial layer of about ?-inches thickness of sandy
loam overlying about 43 inches of red clay and clay loam above
saprolite derived from acidic (light-colored) rocks.
The next most common soil series near the site is Appling sandy
loam. This series also has a texture ranging from clay to sand,

with fine sandy loam dominating. Slope, permeability and
drainage characteristics are similar to the Cecil sequences.
Soil reactivity is slightly more acidic, in the range of 4.5 to
5.5. A typical profile would show horizons of a surficial sandy
loam of about 9-inch thickness over about 37 inches of clay and
clay loam developed on saprolite. The Seneca sandy loam is a
minor series and is not described further by the Soil
Conservation Service.
Significant features of the described soil sequences are that
they are derived directly from saprolite, which is derived
directly from the bedrock, and that they have moderately low
permeabilities affecting infiltration and percolation. Alluvial
deposits of the streambeds apparently have no influence on
dominant soil types adjacent to the site.
Where agricultural influences have operated, the upper profile of
the soil sequences has been altered variously depending on the
type of crops and the method of cultiviation. Where cultural
processes have operated, the original soil profile may have been
cut away to varying depths, or covered by fill or construction.
The fill may, in turn, develop a complete soil profile; however,
none has been distinguished in the vicinity of the site.

3.4 Regional Structure
In the Inner Piedmont, the principal regional structures trend
northeast-southwest, parallel to the trend of the Province.
Foliation and lithologic boundaries tend to strike northeast and
dip southeast. This complex structure developed during the many
complicated events of the Appalachian Orogeny.
Major thrust fault traces in the southern Appalachians trend
southwest/northeast. The Brevard Zone is one such thrust fault
which· borders the Inner Piedmont to the northwest throughout most
of the southern Appalachians. Recent COCORP surv~ys (Cook et al,
1979) suggest that the Brevard zone is a thrust fault rooted in
the basal thrust of the Blue Ridge and Piedmont. This zone has a
history of both ductile movement and brittle movement (Hatcher,
1984) . The Kings Mountain Belt, which borders the Inner Piedmont
in North Carolina, may or may not be a thrust fault.
Four regional joint sets exist in the Inner Piedmont. These
joint sets trend approximately north-south, east-west,
northwest-southeast and southwest-northeast.

streams of a given location tend to be in hydraulic
and hydrologic communication with the upper ground water, whether
in overburden or in rock. Thus, consideration of the patterns of
recharge, interflow and discharge cannot be ground-water
separated from the considerations of the source, flow and
confluence of the local streams.
3.5.1 Ground-Water Flow
As noted in the preceding section, the pattern of development of
the stream courses is closely related to the trends of the
underlying geologic structure. The patterns of the ground-water
movement are

the shallow ground water generally follows the

valley slopes become areas of discharge; and intermediate fields
become areas of interflow and vadose recharge. Ground water in
the shallow rock is found in the joint and fracture systems.
These are developed with the geologic structure or fabric.
Therefore, the occurrence and the controls on flow of ground

The first of these represent areas

pattern of flow of surface water
develops. The shallow ground water has similar trends. However,
other hydrologic features are represented by these topographic
and geologic structures: the ridges and spurs, in areas of
recharge and interflow, act as ground-water divides from which
flow paths diverge; the stream courses and the draws also act as
ground-water divides in discharge areas, toward which water flows
from all directions except one, and from which water flows in
only that one direction. Thus, the ridges divide the flow of
both surface and ground water away from their axes, while streams
collect the discharge of surface and ground water and minimize
the potential of those waters to cross their axes and flow to the
other side of the stream course.
The streams in the upper reaches of the water courses are
generally fed by baseflow of ground water from the overburden and
the shallow rock. In some cases, but usually in the lower
reaches of broad valleys, the streams become recharge zones for

Streambeds that are sufficiently incised in the upper reaches of
the courses to intercept the top of the rock act to cut off the
overburden system completely.
The relations of surface and ground water discussed above are
generally applicable to the three conditions of the shallow
ground water: phreatic, confined or semi-confined. The vadose
condition is not directly relevant to the investigation except to
indicate passage of water from the land surface through a zone of
aeration to the phreatic ground water, as recharge to the water
table.
Phreatic ground water is generally the shallowmost layer of
subsurface water comprising one hydrologic system. The surface
of the phreatic system, the water table, lies in equilibrium with
atmospheric pressure and has free communication through the zone
of aeration with surface waters and precipitation. Thus, water
at the surface can, under ordinary conditions, descend to the
water table as recharge. This water may then move with the flow
of the water table to surface discharge in a stream or swamp, or
as recharge by interflow

to another phreatic, confined or
In a confined or semi-confined system, a physical partition
separates that system from the upper (phreatic) system. In a

confined system, this separation is complete; in a semi-confined
system, there is some limited communication across the partition.
A semi-confined system occurs where the overlying strata is not
completely impermeable, but has significantly reduced
permeability compared to the underlying more premeable unit. In
this case, water can move vertically through the semi-confining
layer in either direction, depending on the relation of head, but
at a significantly lower rate than the water in the permeable
unit can move horizontally.

In the Piedmont, the upland regions are generally under phreatic

The intermediate fields similarily receive recharge to the

recharge to a confined or semi-confined system is dominantly from
interflow from the uplands. Discharge in stream valleys is
largely from the phreatic system, although it may also be from
any confined or semi-confined system physically intercepted by
the streambed. Figure 3-1 shows a schematic diagram of the

hydrologic cycle and illustrates the concepts of phreatic and
semi-confined systems. The Figure indicates that preciptation
falling across a given region will either return to the
atmosphere by evapotranspiration, travel to streams by overland
flow or infiltrate the ground.
Once in the ground-water system, the water flows vertically
downward to join the regional, horizontal flow. If this flow
becomes divided by some hydrologic partition, the flow in the
shallower regime is typically under phreatic conditions, while
the flow in the lower regime is typically under confined or
semi-confined conditions. Flow under phreatic conditions has the
characteristic of a water-table being in some free communication
with the conditions at the surface, and continuously transferring
water back and forth between the surface and the phreatic
system. In a confined or semi-confined system, the physical
partition separates the upper and lower ground waters either
completely or to some lesser degree, respectively. The water can
then continue horizontal flow until the discharge area is
reached.
Figure 3-1 further indicates that a properly designed assessment
program would be able to examine the area above the water table
through which percolating water travels to reach the main

evaporation and vegetation demands (evapotranspiration) may
exceed the rate of precipitation, drawing the excess from storage
in the soil. This is, in part, responsible for a decline in
water levels in the ground to a low between October and
D_ecember. Subsequently, the decreased demands of
evapotranspiration in the autumn allow the ground-water levels to
rise from December or January to a high stage in April or June.
During these months, when evapotranspiration is minimal, the
precipitation is usually more steady and less intense than during
the summer, resulting in less overland flow and allowing more
water to infiltrate and percolate through the soil to the
ground-water system. The flow of ground water in the Piedmont is

Peace (1966) found that most domestic and farm wells drilled into
the gneiss/schist obtained adequate yields at depths ranging from
about 100 to 200 feet.
While the circulation of ground water in the quartz monzonite and
pegmatite dikes occurs also in the joints and fractures, similar
to that in the schist/gneiss, the water-bearing properties of the
unit are laterally inconsistent because of the complex patterns
of lineation. Well reports indicate that these rocks often yield
water from one or more separate levels, implying a complicated
interconnection of joints and fractures.
3.5.2 Ground-Water Quality
The natural quality of the ground water is a reflection of the
mineral constituents of the soil and rock through which the water
has circulated. The quality of ground water in the mica schist
and gneiss complexes is reportedly good to excellent for the
common parameters. Iron content may be slightly high. Among the
samples tested by Duncan and Peace (1966), iron content ranged
from

The quality of ground water in the quartz monzonite is also

4.0 GENERAL GEOLOGY OF THE SITE
This section provides a description of the physical conditions of
the site. The description derives directly from the data and
analyses of the RI with the inclusion of. selected information
from the previous S&ME investigations at the site. The section
discusses the physiography and geology of the site with the
exception of the ground-water regime, presented in Section 5.
4.1 Physiography and Hydrology
4.1.1 Topography
The general topography of the site has been discussed in Section
1.4. During the course of the RI, a survey map of the topography
of the site as it existed in February 1985 was prepared by
Landmark Engineering, Co. (Figure 1-2). Surveys by Davis and
Floyd, Inc., overlaid the various data stations on this map.
. This information is the basis for the diagrams presented in this
report indicating various physical features. The aerial
photographs and interpretations provided by EPA/EPIC (1986)
supplemented these surveys.
The air photo interpretations indicated various surface features
I potentially associated with former disposal practices that have

been since erased or covered by plant development. S&ME has
prepared a superposition of these features on a base map made
from the RI topographic map. This compilation (Figures 1-4A and
1-4B) indicates the probable locations where some sort of debris
or staining might be found. These will be compared to the
results of the test excavation and boring in the appropriate
sections.
As noted below, S&ME's investigations indicate that the land
surfaces, including some of the wooded areas, have been altered
by cut and fill. The courses of the perennial streams, however,

activity.

on 27 February 1986. A storm occurred in mid-March, allowing

(National Oceanographic and Atmospheric Administration) indicate
that the precipitation preceding the baseflow sampling had been
0.05 inches three days previously, with a rainless period of five
days preceding that. These records also indicate that 0.43
inches of rain fell on the day of the storm flow sampling.
4.1.3 Surface Hydrology
The general drainage of the site forms a dendritic pattern
flowing in various directions locally, but dominantly to the east
(Figures 1-1 and 1-2). As noted on these Figures, there is a
confluence point for all perimeter streams lying about 2500 feet
east of the southeast corner of the site.
The established local drainage is fed from various surface
sources within the site, dominantly as sheet-wash or along
controlled paths such as culverts and ditches.
During the geologic mapping along the streambeds, S&ME noted that
I the beds are generally incised to or into the top of rock. The

maximum cut into rock found was less than 5 feet. The sediment
found in the stream was the normal bedload of a stream
approaching maturity. That is, the bedload was dominantly sandy,
indicating some distance of transport without a strong influence
of advancing erosion locally during normal flow. Thus, the

indications are that the streams have cut vertically through the
overburden and are in some communication with the rock. Along
isolated reaches, the streams rested on rock without having a
detrital bedload, indicating that some downcutting is still
occurring.
Further analysis of the valley floors indicates that there are
generally broad floodplains around the creeks, but that the
creeks are incised deeply in their courses. This would indicate
that the streams have been at least partially rejuvenated and had
returned to vertical erosion. This is apparently occurring after
a period of dominantly horizontal erosion, and deposition of

or, less frequently, as infiltration to the ground-water system.
The relationship between the ground-water-and surface water
systems in the Piedmont generally is that the shallow ground
water usually mimicks the divides and directions of flow of the
surface system, and that the surface of the water table
approximates the shape expressed by the topographic surface
(Figures 1-1 and 1-2). Further, the streams usually communicate
freely with the ground water in some fashion. This communication
is expressed by the stream being either gaining or losing; that
is, either gaining water from the ground or losing water to the
ground. The general conditions are that the streams of the
Piedmont gain throughout their length. In some circumstances,
the farthest headwaters of perennial streams may exist under
losing conditions; however, this is not commonly extensive.

The flows recorded indicate broadly that the streams gain
discharge from the ground water under the usual conditions of the
Piedmont during baseflow conditions. In particular, the small
tributary joining the reach between Wiers 030 and 028 has a very
short length and appeared during field inspection to be a spring
fed by the ground water; the increase of about 20 gpm between the
stations most probably represents contribution from the
ground-water system.
The

incision of the streams through the overburden indicates that
are free to receive discharge from the overburden and, also,
some contribution from the upper rock. Further, this
interception would include the types of the systems encountered,
whether phreatic (water table), semi-confined or confined. The
indications from the geologic survey and the stream measurements
are that the perimeter streams intercept the discharge of ground
water from the overburden and the upper bedrock of the site. The
indications from the general pattern of stream and ground-water
divides are also that ground-water flow under the streams to the
opposite slope would be highly improbable.

appropriate interpretation of the data derived. The information
available from the previous studies, particularly S&ME (1982),
was reviewed and incorporated where appropriate. The
interpretations considered the material exposed at the surface or

rock. In the latter case, a reconnaissance analysis of

indications are interpretations by the analyst, but have, in some
cases, been confirmed by direct means. The direct inspection of
the shallow subsurface proceeded with the excavation and boring
programs. Figure 4-2 indicates the pits and borings in which
native materials were encountered without identifiable fill and
in which either clean, demolition or disposal fill was
encountered. The disposal fill was mapped by the occurence of
plastic product or liquid, in whatever quantity; this is the main
concern in the identification of contaminated areas and sources
of contamination. The logs of the test pits appear in Appendix
H. This distribution is represented on Figure 4-2 indicating the
relevant areas.

of the emergency holding ponds and north of the aeration basins.
This area appears to enclose the majority of buried disposal
sites found. The distribution and types of buried disposal
facilities agree closely with the interpretations of the aerial
photographs (Figures 1-4A and 1-4B). The disposal pits found by
excavation were sufficiently close together that, for the
purposes of the RI, they form a single unit, indicated primarily
in the area of the upper lawn. Significantly, where the sides or
bottom of a disposal pit were exposed, no liner or other
containment or control structure was found to isolate the pit

from the subsurface material or from ground water. In the
examination of the pits, no undisturbed soil profile was found at
the surface. The profiles found were immaturely developed either
in fill or on the cut land.
4.2.2 Geologic Profile
By utilizing the characteristics ' ' , of the material comprising or
immediately underlying the topographic surface, the preceding
section identified the potential primary or original sources of
contamination found in the subsurface. The presentation in this
section considers the native unconsolidated and rock materials
underlying and proximate to these areas of made land. The native
materials outside the disposal areas represent the medium through
which contamination may be transported from the original sources.
The discussion of the regional geology indicated that the
material underlying the site could be expected to be saprolite
over igneous/metaigneous or metamorphic rock, with localized
areas of alluvium in the stream courses. The geologic mapping,
and exploratory excavation and boring, confirmed this
expectation. Alluvium was found in the streambeds. The pits
penetrating the fill, or excavated where fill was absent, exposed
a profile in the overburden of saprolite, usually with sufficient
compositional and textural indications to permit association with

Samples from the borings also encountered saprolitic material of
various compositions and textures. The rock cores recovered were
dominantly gneiss, with a common association of schist.
Figure 4-3
the top of
indicates the thickness of the overburden found above
rock. Figure 4-4 portrays the interpreted shape of
the surface of the rock below the overburden. Figure 4-5
represents the plan distribution of rock types inferred from
regional descriptions and from the coring during the RI. The
stratigraphic profile of the site is presented on cross-sections,
oriented in plan on Figure 4-6 and presented in Figures 4-7A
through 4-7G.
4.2.2.1 Overburden
The descriptions from the test pits (Appendix H) provide the most
representative characterization of the soil and fill examined
during the RI. The test pits exposed a broader section of the
subsurface and allowed description of the most prevalent and
relevant composition and texture of the material. Further, the
test pits allowed a better appreciation of the compositional,
textural or mechanical structure of the overburden, compared to
the smaller samples provided by test boring.

The pits across the study area that encountered native material
uniformly found either the lower zone of saprolite retaining I
structure or fragments of the parent rock, or regolith presenting
an appearance most reasonably associated with the upper, and more
weathered, zone of saprolite.

the undifferentiated clays and silts, with quartz, plagioclase,
garnet, muscovite and biotite found in the sand and gravel
fractions. The saprolite tended to coarsen downward, with
occasional layers of clayey, silty sand in the lower profile.
The thickness of the overburden explored by the test borings
(Figure 4-3) (Appendix I, with the schematic diagrams of the
monitor wells installed presented in Appendix J and the well
data summary in Appendix K) would normally be controlled by the
conditions under which the weathering had occurred and by the
conditions of subaerial erosion and deposition. However, the

Figure 4-4 represents the surface of the rock encountered in the

the surface indicates that a ridge of rock trends somewhat east

broadly with the interpretation of the maps and photographs,'and
with the regional trends. A third trend was noted in the streams
where an
horizontal
unconsolidated bedload was absent: an apparently
or nearly horizontal fracture plane or parallel
sequence of planes often formed the bed of the stream. A further
discussion of the geologic mapping appears in Appendix L.
4.3 Type and Distribution of Fill
Three broad categories of fill were identified across the site:
clean, demolition and disposal. Clean fill was the type of
granular material used for construction purposes, either to
support structures or to raise a depression to grade. Demolition
fill comprised the artificial material not directly associated
with
blocks,
clean

For the purposes of the RI, the ground-water regime is, in the
absence of confirmed, adverse effects on a living population, the
most sensitive indicator of the effect of a disposal site on a
general environment. The ground-water regime includes the
physical matrix of the subsurface (described in Section 4), the
sources of contaminants within or affecting that matrix, the
presence and occurrence of ground water in the matrix, and the
conditions of ground-water flow. The latter consideration

involves the ability of the matrix to allow water to flow, the
availability and volume of water contributing to that flow, the I
energy of the regime that may be used to move the water and the
area or zone receiving the discharge from that flow.
5.1 General Considerations
The discussions of ground-water flow derive from various
manipulations of the rational form of Darcy's Law: Q = KAi;
Q = total discharge, L3 /T
K = hydraulic conductivity, L/T
i = hydraulic gradient, L/L
A = cross-sectional area at right
angles to the flow direction, L2
The hydraulic gradient value is commonly expressed as the
magnitude of the change in energy as it is expended in moving the
water along the direction of the gradient vector (indicating both
the direction and the magnitude). The magnitude is usually
expressed in the amount of vertical change per unit of horizontal
change; e.g., in feet-vertical/feet-horizontal (ftv/fth).
The final consideration of the presence and flow of ground water
is the matrix in which it occurs. For the CFO/SHELBY site, the
relevant matrices are porous and fracture media. The porous

be no significant barriers not considered.
The case of a fracture matrix is somewhat different in that
fractures are typically open only at shallower depths; at greater
depths, they may exist, but may not be sufficiently open to
permit the free passage of water. However, where the fractures
are open, the following discussion applies to the general
conditions of flow.

At the CFO/SHELBY site, ground water exists in the granular
material of the overburden and in the fractures of the upper
rock. However, the flow of water in the rock appears limited to
the uppermost system of fractures. This is indicated by the
increases in recovery ratios and RQD (rock quality determination)
{Appendix I) with increasing depth. These calculations reflect
the tendency of the rock to become more competent, and less
fractured and open, with depth. A further indication of
decreased circulation of ground water is the decrease with depth
of features associated with such circulation; notably, a decrease
in weathering, iron-staining and the growth of secondary,
hydrothermal minerals, both in general and on fracture surfaces.

permeability of undisturbed samples. The vector conductivity (K)
indicates the ability of the matrix to conduct water from, or to,
the well in all directions. This value is most strongly
affected, in a porous matrix or in a fracture matrix with an
equivalent porosity, by the horizontal hydraulic conductivity
(Kh)' with the vertical hydraulic conductivity (Kv) usually
being significantly less. In granular material, the minimum
conductivity contrast for Kh:Kv is about 10:1; a contrast of
1000:1 is not uncommon. No general rule can be stated for the
conductivity contrast in fractured rock or jointed saprolite.

compared to 1.8 ft/d for the saturated overburden, is not
unexpected.
The overburden wells have interception intervals segregated by
depth within the saturated zone; the shallow wells have screened
intervals within the upper third of the saturated matrix; the
intermediate, in the middle third; and the deep, in the lower
third. Further, the deep overburden wells rest on the top of the
rock beneath the site and may be influenced by the hydraulic
conductivity of the rock and of the layer of weathered and
fragmented rock along the top of rock. The shallow and
intermediate intervals probably indicate the most common value of
hydraulic conductivity for the overburden, while the values of I the overburden and the rock indicate the most common value for

value for the overburden (excepting the phreatic interval) is
about 1.8 ft/d.
The wells of the rock interval intercept the upper 25 feet of the
rock through their sand packs. The flow of water through the
rock is controlled by the pattern of fractures and joints in the
rock, and does not allow discrimination between vertical and
horizontal hydraulic conductivity by well-head tests of flow.
The method of the tests accounts for the increased interception

average value of the overburden.
The hydraulic conductivity of granular materials is controlled by
the interconnected porosity, or interstitial space, of the
unconsolidated mass. In rock, the conductivity is related to the
ability of the ground water to flow along the openings and narrow
passages created by fracturing and jointing of the rock mass. In

that provide the least permeability. The permeability, or
hydraulic conductivity, of saprolite may also be affected by
relict expression of jointing or fracturing preserved during the
weathering process. The orientations of these relict features
follow the original trends of the parent rock, and cannot be
predicted for the purposes of separating vertical and horizontal
conditions of flow. The hydraulic conductivity of the saprolite
is then dependent on the undefined proportions of porous flow and
fracture flow components.
5.2.2 Vertical Hydraulic Conductivity
The well-head tests provide a representation of the vector
hydraulic conductivity exhibited by the water-bearing layer.
Laboratory tests of permeability are routinely performed to
estimate the vertical permeability (Kv) on a small sample of
the matrix of the water-bearing layer. Of necessity, this type
of test cannot account for the larger, medium-scale influence of
the fracture traces.
S&ME (1982) reports that tests of vertical permeability on
undisturbed samples yielded values of Kv averaging 0.068 ft/d
(2.4 X 10-5 cm/sec). This value is about one order of
magnitude less than the vector hydraulic conductivity.

5.3.1 Horizontal Hydraulic Gradient
Water level elevations established during the RI (Appendix M)
provided the data for calculation of horizontal gradients
(Appendix 0). For the purpose of this RI, 12 March, 27 May and
7 July 1986 were used to calculate the gradients. These dates
correspond with sampling events and are representative of the
patterns of ground-water flow throughout the RI.

The direction indicated also corresponds to the

(equipotential) lines of a flow net. The magnitude of the
gradient indicates the maximum difference in head along a unit
length of the direction. This magnitude indicates the maximum
energy available to drive the movement of ground water between
the points, and within the system.
The calculations of gradient involved solution of 'three-point
problems' by standard methods. In this technique, three

values for the elevation of the phreatic or potentiometric
surfaces. In this triangle, three apparent gradients appear
(excluding the trivial case of two or more elevations being

lowest; and from the middle to the lowest. The calculation by
standard methods resolves the apparent gradients into the single
average gradient for the system within the triangle. Since the

Typically, the phreatic surface would respond most strongly to
the rapid fluctuations of recharge from the surface and to the
horizontal and vertical distribution of this recharge within the
ground-water system. Thus, the direction and magnitude of the

At the CFO/SHELBY site, the secondary topographic structural
patterns are at an angle to the primary pattern, and are mimicked

previously. Therefore, the general flow in the overburden would
respond to the smaller draws of the upper reaches of the
tributaries around the site and discharge to the east, while the
flow in the rock and deep overburden would respond to the larger,
regional pattern and discharge to the southeast, in the direction
of Buffalo Creek and Broad River. The discharge toward the major

major features would also be deflected in the direction of flow
of these streams and would not be orthogonal to the closest
approach of these streams to the site.
Given these general directions, the consistency of the gradients
would imply a magnitude for ih of about 0.023 for both the
overburden and the rock.
5.3.2 Vertical Hydraulic Gradient
The vertical hydraulic gradient represents the potential for the
movement of ground-water between zones of the water-bearing
matrix, and between the ground-water system and the surface water
system. An upward gradient indicates movement from deeper zones
of the ground-water system to shallower zones, and from the
ground water to surface water as discharge. A downward gradient
indicates a tendency for the ground-water system to accept
recharge from the surface and to distribute this recharge to
lower parts of the system. The direction of the gradient

I

indicates the condition of recharge or discharge, as a downward I
or upward tendency. The magnitude of the gradient indicates
whether these conditions develop as a result of flow, represented
by a relatively lower magnitude, or of confinement by lessened
permeability, represented by a relatively higher magnitude. The
similarity of hydraulic conductivity found in the field tests

indicates that the general patterns of the CFO/SHELBY site have
developed as a result of flow; however, certain locations,
particularly station T, presented stratigraphic evidence that
confining or retarding layers may be found locally and with
limited lateral extent beneath the site.
Vertical gradients appear where the phreatic or potentiometric
surface elevations in the separate wells at a given station
differ. (Note: For this comparison, the wells must be within a
negligible horizontal range of each other, as they are at the
stations discussed below. This minimizes an impression of the
horizontal gradient on the measurement of elevations between
wells). In the case of a well intercepting a shallow interval
having a head higher than that of a well intercepting a deeper
interval, the direction of the gradient would be downward; and
lower, upward. The magnitude of the gradient is calculated as
the change in head divided by the distance between comparable
reference points in the wells or across a layer of very low
permeability. Since no extensive impermeable layer was found at
I the site, and since the head of a column of water in a well is
I

the same at every point in the column, and since the water in the
sand pack of the well (having a significantly higher conductivity
than the formation) has effectively the same head as the well,
the reference datum for each well was taken as the bottom
I elevation of the sand pack. Thus, the calculations of magnitude

vertically. The magnitudes are more appropriate to this than the
head differentials by making some account for distribution of
head along a vertical length. The vertical gradients for the
stations with nests of monitor wells are shown on Table 5-1.
The gradients display a distribution of orientations and values.
This distribution has been charted for areal comparison in a
schematic representation (Figure 5-1), showing that the southern
part of the site has a dominantly upward head, while the
remainder of the site has a dominantly downward head. The lawn
area and the disposal pits north of the north fence lie in this
area of downward gradient. The pattern represented compares with
the inferred pattern of geologic units (Figure 4-5), representing
an interpretation of a regional trend.

two sets of cross-sections indicates that the ground-water
surfaces follow the trend of the dipping bedrock, implying a
structural control on flow and discharge at the site. Comparison
of the ground-water cross-sections and the table of gradients
indicates the orientations schematically illustrated in Figure
5-1.
5.4 Discharge
The last variable in the calculation of horizontal discharge is
the cross-sectional area through which the ground water flows.
For the

reasons presented in Section 5.5, selection of a
front for the site would be difficult. For the

suitable
combination of length and depth; however, a reference length of
100 ft, with a depth of 10 feet, will be used. For the rock, the
depth of interception of 25 feet into the rock restrains the
reference length to 40 feet, to provide a comparable dishcarge
area of 1000 ft2 . For the equation Q = KAi, with the values
presented above, the comparative discharges are:

Thus, for every 1000 ft2 of discharge front, as an average for
the site, about 310 gpd of discharge could be expected.
The RI field program was conducted during conditions of drought,

than of a longer term pattern of discharge. The flow of
about 310 gpd per 1000 ft2 of discharge front can be expected
to be somewhat lower than the general value during normal
conditions of precipitation.

water from the ground. In addition, the reservoir on the south
side of the site, located at an artificially high elevation,
serves both as a ground-water divide from which water flows and
as a continuing source of water to the ground. The overall
pattern of flow at the site appears in the variants of A through
c of Figures 5-3A to 5-7C for each of the stratigraphic intervals
intercepted by the monitor wells. The recharge areas appear as
the upland areas of the site, while the discharge areas, along
the stream courses, appear along the contours with the lowest
value of head. The contours of the available maps for the
selected
discharge
dates have similar shapes and support the indications of
to the perimeter streams. The shape of the lowest
contours also approximates the shape of the discharge front along
the downgradient perimeter of the site.
The similarity of the ground-water contours and gradients, and
the extensive range of dominantly downward head, indicate that
the disposal area lies under conditions of phreatic recharge. In
this case, water at the surface may, at whatever rate, move to

5.5.2 Vertical Potential
The two broad regions characterized by particular orientations of
the vertical head are the southern part of the site, indicating a
dominantly upward head, and the northern part, including the
disposal area, showing a dominantly downward head. The area of
downward head supports the inference of phreatic recharge from
the surface to the upper ground water, and then to the remainder
of the ground-water system. The area of upward head presents a
more complex pattern, influenced by the lithology of the matrix,
the impression of the topographic flow divides and the presence
of a large areas of open water at higher topographic elevations.
The south

The borings at station T encountered lenses of
material at higher elevations than the actual top of
rock. These lenses had relatively small thicknesses, but would
probably indicate a barrier to the free circulation of ground
water. The reservoirs of the recreation pond and polishing ponds
lie in a topographically elevated area, and themselves may
represent ground-water divides. The elevated position of the
water in this type of terrain would characterize a divergence
divide from which water flowed, in this case to the north, east
and south. The ponds would serve as sources of head to the
subsurface, and would distribute this head to the ground-water

Thus, general patterns of subsurface communication would
explain the development of upward heads in the region affected by
the reservoir and the topographic divide.
The upward head of the southern region indicates a tendency for
water to move from deeper to shallower layers in the ground. The
laterally limited stratigraphic barriers (rock lenses), however,
have the property to contain this tendency and limit actual flow
of water. The potential for deep recharge from the surface is,
therefore,

5.6 Distribution of Flow from the Disposal Areas
However,

The pattern of flow represented by the ground-water contours of
the various interception intervals (Figures 5-3A to 3C) shows a
distributive movement from the ridgeline containing the site
along the slopes of the ridge and down the spurs to the stream
courses. This pattern includes the disposal area beneath the
upper lawn and the isolated disposal sites to the north. The
overall trend of the flow is to the east and into the streams
along the topographic perimeter of the site.

The disposal areas are under normal phreatic conditions of
recharge and flow. Therefore, if water percolates from the
surface through the disposal fill, it may enter the ground-water
system and discharge to the streams intercepting that system.

6.0 CHEMISTRY AND CHEMICAL GEOHYDROLOGY
6.1 Introduction
This section presents the data available from the analytical
chemical program of the RI, primarily reported by Davis and
Floyd, Inc. The full
appears in Appendix P,
Q. Relevant information
following discussions.
compilation of the analytical results
with related correspondence in Appendix
has been extracted for use in the
This information has been prepared by
reorganization of the reported analyses and by segregation of
species of the chemical parameters. The ground-water sample
collection summary sheets are presented in Appendix R.
Consideration of the sampling and analytical program of the RI,
as approved by the EPA, indicates that the sampling and analyses
of Phases II and IIA are the most appropriate for the discussions
of the transport trends of contaminant outfalls. The Phase II
and IIA sequences characterize the background and distribution
areas vertically and horizontally more completely than other
combinations. However, all of the analyses from each round
(Phases I, IA, II and IIA) of sampling have been considered and
will be discussed where appropriate.

CFO/SHELBY, NC FACILITY
DOCUMENT NO. 85-050A-0056 REV.1-0587
PAGE NO. 6-2
The Phase designations refer only to calendar dates of sampling.
The analyses of Phase II and IIA are more appropriate to the
purposes of the RI since they included the downgradient wells
installed as part of the RI.
6.2 Identification and Characterization of Selected
Contaminants
Tables 6-1 and 6-2 present the data extracted from the main body
of analytical results as representative of the general patterns
found during the RI. These discussions are limited to the CERCLA
Hazardous Substance List (HSL) compounds and include the Clean
Water Act Priority Pollutants plus about 30 additional
compounds. Non-HSL compounds were also quantitatively identified
in some samples and are reported in Appendix P. The non-HSL
compounds are not generally discussed in the text. Consideration
of the analytical parameters falls into three main categories:
field parameters, metals and organic compounds or groups of
organic compounds. A summary of health and environmental effects
of selected compounds and elements, is listed in Appendix S.
Government regulations which are applicable to chemicals present
on this site are also identified. Maximum Contaminant Level
Goals (MCLGs) for regulated ground-water contaminants are taken

Other sources may be referred to where a MCLG or MCL is not
available. Although chemical compounds are also present in soils
as well as ground water, there are no regulations regarding
concentration limits for soil contaminants.
In characterizing contaminants at this site, discussion of more
toxic and frequently occurring compounds is emphasized.
6.2.1 Field Parameters
The field parameters considered herein are pH and Sc (specific
conductance). These are values measured in the field at the time
of sampling. The pH is a dimensionless value indicating the
activity of the hydrogen ion in an aqueous solution. A value of
7.0 indicates neutrality, while above 7.0 is considered basic,
and, below, acidic; the usual value for drinking water standards
I lies from 6.5 to 8.0.
I
I
Sc indicates the ability of the aqueous solution to conduct an
electric current across a representative length; the units are
usually expressed in umhos/cm (micromhos per centimeter). There
I is no drinking water standard for Sc. However, Sc is directly
related to the total dissolved solids of an ionically balanced I solution by the approximate ratio of: 0.58 umhos/cm = 1 mg/1
I (milligram per liter or parts per million) of TDS. The usual

at the site was restricted to treatment of the wastewater for I
elimination of bacterial growths. This practice has ceased.
6.2.3 Organic Compounds and Groups of Organic Compounds
Organic compounds and groups of compounds are considered where
the compound or group has been detected in the ground water of
the site, and is of some regulatory significance, or is commonly
found or is present in relatively high concentrations. Groups of
compounds are the sums of related species in the sample.
6.2.3.l Total Volatile Organic Compounds
This value is the additive sum of the HSL volatile organic
compounds found in each sample, regardless of species. The value

Benzene, the unsubstituted parent of this class of compounds, is I
necessary in the synthesis of many organic compounds such as
polymers, detergents, pesticides and pharmaceuticals. Benzene is
also used as a raw material in the production of synthetic rubber

concentrations, benzene and other volatile compounds in this
class may cause central nervous system depression.

6.2.3.8 Phenol and Phenolic Compounds
Phenol, 2-chlorophenol,
and methyl phenol were
4-chloro-3-methylphenol, 4-nitrophenol
detected in ground water at the site.
With the exception of methylphenol, these compounds were also
present in soil. Pentachlorophenol was also detected in soil.
Phenolic compounds are used in the manufacture of resins and
plastics and in the synthesis of drugs, antiseptics, fungicides,
insecticides, preservatives, dyes, detergents and plasticizers.
Phenol, the simplest representative of this group, is corrosive
and can damage the skin if applied in sufficient concentration.
Phenol is well absorbed from the gastrointestinal tract, lungs
and skin. Systemic phenol poisoning has been shown to damage the
liver and kidneys. Chronic poisoning is rare. It is proposed
that water containing less than 3500 ug/1 of phenol is safe to
I drink (Sittig, 1985).

textiles and explosives. Exposure to carbon disulfide may cause
injury to the nervous system. Symptoms of acute toxicity include
profound mood changes and uncontrollable anger. Lesser exposures
may cause headache and dizziness. A permissable ambient water
criterion of 830 .ug/1 has been proposed for carbon disulfide
(Sittig, 1985). Carbon disulfide was also found in soil at the
site.
1,3-dichloropropene is used as a soil fumigant and nematocide.
In high concentrations it is irritating to the skin, eyes and
respiratory tract, and has caused liver and kidney injury in
animals.
1,2-dichloropropane is a solvent for fats, oils, waxes and gums,
and is used in solvent mixtures for cellulose esters and ethers.
Acute poisoning in animals produces signs typical of solvent
toxicity, including central nervous system depression and kidney
and liver injury. Recent studies of 1,2-dichloropropane indicate
that high doses may induce cancer in mice and possibly rats.
Based on this information, the EPA Cancer Assessment Group has
calculated a proposed MCLG for 1,2-dichloropropane of 0.56 ug/1
in drinking water. This estimated concentration is suggested to
cause 1 excess cancer incident in 1,000,000 persons over a
lifetime.

regulatory limits have not been set for certain of these species,
preliminary comparative calculations of the most common organic
compound have been made from non-regulatory information provided
by industrial and academic sources.
6.3 Ground-Water System
The ground-water system considered in Phases II and IIA comprises
all wells at stations C, D, P, T, AA, BB, CC, DD, EE, FF, GG and
HH. The wells at stations C and D lie in the background
locations. Station cc lies in the center of the waste management
area. The well at station DD lies across the flow-path of ground
water indicated in Section 5. The remaining stations T, P, EE,
FF, GG, AA, BB and HH lie in the probable paths of discharge from
the waste management area, and would reflect influence of an
outfall of contaminants from that area.
6.3.1 Field Parameters
6.3.1.1 pH
The values of pH at the stations for Phases II and IIA ranged
from moderately acid, at about 4.4, to moderately basic, at 9.9.
FINAL REMEDIAL INVESTIGATION REPORT

Twenty-two of the 50 samples were more acidic than the drinking
water standards, while 5 were more basic. The remaining 23
samples were within the acceptable range for drinking water.
I
I
I
I

There were no discernable trends of horizontal distribution of I
pH, each value seemingly an isolated occurrence.
The vertical profile of pH at the nested wells tended to exhibit
more basic, or less acidic, values in the deeper wells of the
I
I
nest, except at station GG in Phase II, and stations AA, FF and I
HH in Phase IIA.
6.3.1.2 Specific Conductance
The values of specific conductance (Sc) demonstrated a random
horizontal distribution, with values below the 850 umhos/cm
equivalence of the drinking water standard for TDS, except at
monitor well GG-25.8 and P-31.5 in Phase II, at 1350 and 917
umhos/cm, respectively, (Figure 6-1).
The vertical profile indicated that the shallow wells tended to
have higher conductivities (up to about 1350 umhos/cm), except at
stations AA and FF in Phase• II, and stations AA, FF and HH in
Phase IIA.

6.3.2 Chromium
FINAL REMEDIAL INVESTIGATION REPORT
CFO/SHELBY, NC FACILITY
DOCUMENT NO. 85-050A-0056 REV.1-0587
PAGE NO. 6-75
Chromium concentrations were above the drinking water standard of
50 ug/1 in 19 of the 50 samples. The background station D
provided 2 of the high samples. No other trends of horizontal
distribution were apparent, except that the highest ranges found
in the ananytical rounds occurred in wells around the wastewater
treatment area. These values ranged from about 300 to 775 ug/1
at stations N, R, z and cc.
In the vertical profile, the shallower layers tended to have
higher concentrations, except at stations AA and FF in both
phases, where the rock wells were above the standard.
These values indicate that there may be some contribution of
chromium to the natural regime from the waste management area
(monitors N-53.5, R-17, Z-78.4 and CC-33), and also that there
may be some contribution from of the native suite of metals
(monitors D~27.5 and D-88).
The vertical distribution of chromium indicated by Tables 6-1 and
6-2 appears to favor higher concentrations of chromium in the
shallower wells of the nests. While the monitor CC-33 could show
the influence of distribution from the waste management area in
the shallower zone, the chromium of the shallower wells of the
FINAL REMEDIAL INVESTIGATION REPORT

stations remote from the central area could reflect the influence
of the upper, more weathered zones of the saprolite that are
likely to liberate larger concentrations of cations. The
potential relation of the distribution of chromium to the plant
operation will be more fully evaluated during the FS.
6.3.3 organic Compounds and Groups of Organic Compounds
6.3.3.1 Total Volatile Organic Compounds
The sum of all voes in a single sample ranged up to about 2300
ug/1 at well C-33 (Figure 6-2). There was no consistent pattern
of distribution with position or time. The highest
concentrations of voes were in the middle of the waste management
area and at the station HH, farthest downgradient from that area.
In the vertical profile, no consistent trends were found except
that the deeper layers were more frequently above the mean value
for all voes, with the downgradient rock wells showing some
concentrations of total voes.
6.3.3.2· Total Organic Compounds
The indications of total concentrations of organic compounds were
similar to those of the total voes and are shown on Figure 6-3.

6.5 Soil and Sediment
Similar analyses were performed on the soil/sediment and water
samples. This allows direct comparison of the potential source
with the mechanisms of transport from that source. However, in
some cases, different individual species of an association of
compounds were found in the soils.
The samples of soil and sediment for chemical analysis were taken
from the test pits, the geotechnical borings and the stream
bottoms at the water sample locations. The samples from the
geotechnical borings came from both the standard test boring and
the monitor well construction programs.

The sediments of the stream were sampled at the time of the
baseflow sampling event at the weirs and at the time of the
general stream sampling. The sediments of the emergency ponds
were sampled in each of the four quadrants of each pond.
6.5.2.1 Streams
The sediment of the streams exceeded phthalate concentrations of
1000 ug/kg at stream stations 017, 020, 027 and 029, with the
highest concentration measured at station 029 (13000 ug/kg).
Polynuclear aromatic hydrocarbon compounds exceeded 1000 ug/kg at
station 023; additionally station 023 had the highest

Fourteen soil samples collected from the north and south
emergency ponds, and from STB-5, 6, 7, 10, 11, 12 and 14 were
analyzed for metals by an extraction procedure (EP) toxicity
test. These tests identified the presence of antimony, arsenic,
chromium, copper, lead, nickel, zinc and mercury in the leachate
samples. Results indicate that metal concentrations leached from
the soil samples were lower than regulatory levels which would
classify soil as a hazardous waste.

7.0 SITE ASSESSMENT
FINAL REMEDIAL INVESTIGATION REPORT
CFO/SHELBY, NC FACILITY
DOCUMENT NO. 85-050A-0056 REV.1-0587
PAGE NO. 7-1
The RI study generated new data on the physical setting and
conditions at the CFO/SHELBY facility, along with geochemical
data on the quality of the soil, sediment and surface water on
site, and on general ground-water quality on and at nearby
offsite locations. The data used in the assessment were
primarily generated during the RI, but were supplemented where
possible with historic information on ground-water levels and
previously-generated data on subsurface geologic conditions.
These studies documented the presence of organic and inorganic
constituents in soil and water. The Endangerment Assessment
prepared as part of the Feasibility study (FS) will address the
potential effects of the identified constituents on the health of
potential receptors or the environment.
7.1 Geohydrologic Assessment
7.1.1 Geologic Assessment
The site is located in the Inner Piedmont Physiographic Province
of the Southern Appalachians. The subsurface conditions
encountered are typical of the Inner Piedmont where a mantle of
residual soil overlies bedrock except where altered by man or,
occasionally, alluvial processes. At the CFO/SHELBY site, the

soil surface, the soils become saprolitic and retain the relict I
appearance of the underlying bedrock, including identifiable
mineralogical banding, and fractures and joints. Exploratory I
corings showed the bedrock fracturing to decrease in intensity
and weathering with increasing depth below the top of rock,
indicating a probable reduction in circulation of ground water at
greater depths.
The primary activities affecting the occurrence of residual soils
at the ground surface at the sample locations were the man-made
effects of structural fill associated with the plant
construction, the demolition landfill, and destruction and
disposal of wastes through use of the burn pits and the GRU
disposal pits. The engineered fill encompasses the greatest area

The non-engineered fill consists of the demolition fill and the
disposal fill area. The demolition landfill is located north of
the wastewater treatment plant area and contains construction
rubble, soil, and miscellaneous fiber and debris. The disposal
fill area is located in the wastewater treatment plant area and
encompasses the areas used for disposal of the GRU bottoms and
the former burn pits. The disposal fill area extends beyond the
present plant fence but remains well within the plant property,
and may overlap the demolition landfill in some areas. However,
most of the disposal fill is thought to be located on the western
terrace of the lawn, north of the aeration basins and west of the
emergeri'cy ponds.

observed most notably at Location T.
Comparison of the potentiometric heads in the monitor well nests
indicated a tendency for recharge or downward flow of ground
water in the higher elevations of the site and a tendency for
discharge or upward flow of ground water in the topographically
lower areas. Since the disposal fill and demolition fill areas

However, the location showing the highest organic

subject to receipt of much of the erosional loading from the fill
areas and storm water runoff from the plant production area.

Limited data on the demolition landfill indicate that it

southwestern portions near the disposal landfill, showing
the higher levels of contaminants.
Other apparently isolated areas around the periphery of
the wastewater treatment plant area contained organic
compounds in both soil and ground water.
The compounds most frequently encountered are phthalates,

Ground water beneath the site exists in generally a water

The potential source areas are generally located in
topographically higher areas.
The flow mechanics existing at the site should result in
ground-water flow being toward the perimeter streams with
subsequent discharge providing base flow to the streams.
Ground-water analyses identified the presence of
phthalates, ketones, benzene and related compounds,
phenolic compounds and chlorinated ethenes and ethanes,
with the phthalates and ketones occurring more frequently
and generally at higher concentrations than other noted
compounds.
Volatile organics analysis of offsite wells adjacent to
and down gradient of the plant detected trichloroethene
in James Elliott's well at 14 ug/1: this compound was not
traceable to plant operations and other volatiles were
not detected.
The results of the ground-water analyses varied in
compounds identified and in reported concentration
between succeeding sampling events for offsite and onsite
samplings.

8.0 POTENTIAL REMEDIAL ACTIONS
The Feasibility Study will evaluate the reliability,
implementability, public health and environmental effectiveness
and economic considerations of potential remedial actions. The
FS will also consider the potential for additional contaminant
migration due to the remedial operations, and health and safety
considerations during implementation. The following section
presents a preliminary listing of alternatives for the CFO/SHELBY
site.
A preliminary listing of the remedial alternatives to be
considered during the FS are:
o No Action
0
Consideration must be given to potential receptors of
contamination migrating from the site and the possible
harmful effects if no remedy is implemented. The No
Action alternative is to be addressed in the Endangerment
Assessment as required by the National Contingency Plan,
and will serve as the standard against which the
effectiveness of the other alternatives will be
considered.
Offsite Removal and Disoosal
This alternative could be used for the GRU
other isolated sources. Due to excavation
requirements, this alternative may not be

Furthermore, it is not a permanent remedy. Due to this
lack of permanence, and the present regulatory preference
for permanent solutions, this alternative is not
considered a prime candidate, but will be considered.
Onsite Containment
This alternative would involve removal of the source and
encapsulation of the material in a secure landfill cell.
This alternative would involve permitting and long-term
maintenance, monitoring and liability. This is not a
preferred alternative, but will be considered.
Onsite Stabilization/Solidification
This alternative is intended to immobilize the waste
constituents. This would involve excavation of the
amenable portions of the source area, and solidifying
them with a pozzolonic material or by one of the
commercially available processes. Once this was
completed, the solidified material could be landfilled on
site or replaced into the area where it was removed.
This alternative would involve some long-term monitoring,
but should not involve the permitting requirements for
onsite landfilling.
Incineration
Incineration may be the technically favored option since
it destroys the organic fraction of the waste. However,
metal-laden ash may need to be handled by solidification
or offsite disposal.
Ground-Water Extraction and Treatment
Based on the results of the Endangerment Assessment,
ground-water extraction may be needed to abate the
constituents already in the ground water. This would
involve extraction through pumping. Treatability of the
effluent would be documented as part of the FS.
Composite Alternative
The remedial actions outlined in preceding paragraphs
treat the source area and site ground water. Based on
the results of the Endangerment Assessment, a combination
of alternatives may be needed to remediate the site
conditions. Appropriate combinations will be considered
during the FS.
