1.0 INTRODUCTION
1.1 PURPOSE
In June 1984, personnel from the U.S. Environmental Protection Agency's
(USEPA) Region IV office and the North Carolina Solid and Hazardous Waste
Management Branch conducted a physical inspection of the Celanese Fibers
Operations Shelby plant. Hazard Ranking System score sheets and
documentation were completed in July 1984. The USEPA selected the Celanese
Fibers Operations Shelby facility for inclusion on the proposed expansion
of National Priority List (NPL) sites in September 1984.
In January 1985, the USEPA issued a Work Assignment to Camp Dresser & McKee
Inc. (COM) to perform forward planning activities at the site. This report
is the output of Task l of the Work Assignment which is to provide a
description of the current situation at the site. It includes a
description of the site and its environmental setting, and a su11111ary of the
data collected during previous site investigations. Information
deficiencies and data gaps are identified to provide a basis for the
development of subsequent remedial investigation activities.
1.2 SITE LOCATION
As shown on Figure 1-1, the Celanese Fibers Operations Shelby, North
Carolina facility is located in Cleveland County on State Highway 198
approximately 2 miles south of Patterson Springs, North Carolina and l mile
north of Earl, North Carolina. Shelby, North Carolina is about 10 miles
northwest of the site •
1.3 HISTORY OF OPERATIONS
Operations began at the Celanese Fibers Operations facility around 1960 for
the production of polymer chips, polymer fiber, and polyester texturizing.
The texturizing plant was phased out of operation in 1982.

A waste treatment plant and polishing ponds are located east of and
downslope from the manufacturing plant. Figure 1-2 is a map of the
Celanese facility showing the locations of the manufacturing plant, waste
treatment plant, and waste disposal areas. Reportedly, the treatment plant
was constructed in phases concurrent with the manufacturing plant. During
part of the early years, chemical wastes were disposed of through a ditch
draining .in a generally northwesterly direction. The ditch was replaced
with pipes when the waste treatment plant became fully operational in the
mid-1960's. In 1973, the plant was expanded with the addition of a
polishing pond, two emergency spill ponds, and an additional aeration
basin.
Several areas around the property have been used for waste disposal.
Normal plant and construction wastes were disposed of in an old burning pit
located just north of the aeration basins. North of the burning pit,
glycol recovery unit (GRU) sludge was buried during the early 1960's in
four trenches measuring approximately 25 feet square and 4 to 6 feet deep.
West of the GRU sludge burial area is a former drum storage landfill.
Solutions which failed to polymerize were stored here during the early
1960's. The drums were removed in the mid-1960's and the storage area
backfilled.
Two areas of buried waste are reported to be located to the north and
outside of the main plant perimeter fence. One of these areas reportedly
contains primarily inert materials such as excavation spoil, polymer, and
waste yarn. The other area is said to include miscellaneous soluables and
chemical wastes.
In the period from 1970 to 1978, approximately 2000 to 3000 drums of waste
chemicals and solvents, including lab packs, were stored temporarily in the
area of the former burning pit. All drums were removed from the area by
1978 and sent to outside disposal facilities.
Approximately 21 acres of the northwest quadrant of the property have been
used for sludge disposal since 1978. Permit No. 5002 was issued by the
North Carolina Division of Environmental Management (DEM) for a one-time

application of 4 million gallons (MG) of sludge that had accumulated in the
plant's sludge lagoons over a period of 18 years. Permit No. 7241 was
issued by DEM on March 18, 1982 for the operation of a non-discharging type
sludge land application facility for the disposal of approximately 1.2 MG
per year of digested sludge on the 21 acre site. The reason for the
substantial increase in the rate of sludge production was that alum sludge
from the plant's water treatment facility was also being discharged to the
sludge lagoons. Permit No. 7241R was issued by DEM on October 12, 1983
amending the previous Permit No. 7241 to allow for the disposal of 1.6 MG
per year of digested sludge at the 21 acre site. Permit No. 7241R expires
on December 31, 1986.
Soil and Material Engineers, Inc. (SME) has been conducting investigations
at the site since October 1981. These investigations include a
hydrogeologic evaluation, an electromagnetic survey, and test pit
excavations. The results of SME's work have been summarized in three
documents:

2.0 ENVIRONMENTAL SETTING
2.1 PHYSIOGRAPHY
The Celanese Fibers Operations Shelby plant is located in the southern
two-thirds of Cleveland County which is characterized by a broadly flat and
gently rolling plateau that gives way to mountainous conditions northward.
The plateau is about 900 feet above sea level in the southern part of the
county.
The U.S. Geological Survey (USGS) Blacksville North 7.5 minute quadrangle
map shows elevations ranging from 780 to 860 feet above mean sea level
(msl) in the developed portions of the plant property (see Figure 1-1). An
accurate site-specific topographic map is not available. The USGS
quadrangle indicates that the manufacturing plant was constructed on the
highest elevations of the site with fairly steep drop-offs occurring to the
north and south and more gradual elevation decreases to the east and west.
The plant's waste treatment facilities are located east of and downslope
from the manufacturing plant at elevations ranging between BOO and 820 feet
above msl.
2.2 GEOLOGY
The geology of Cleveland County was described by Duncan and Peace (1966) in
"Groundwater Resources of Cleveland County, North Carolina". Reportedly,
as much as 75 percent of the county area is underlain by a mica schist and
gneiss complex. This complex consists of polymetamorphosed sedimentary and
pyroclastic volcanic rocks.
The coloration of these rocks is generally light to dark gray and weathers
to dull gray, yellow, and various shades of red. The contacts and boundary
zones separating the mica schist and gneiss complex from other rock units
are generally indefinite because of their gradational character.

Included in the complex are geologically younger bodies of quartz
monzonite, gabbro, and dikes and lenses of pegmatite. Duncan and Peace
(1966) reported Toluca Quartz Monzonite underlies approximately 10 percent
of Cleveland County. Examination of geologic maps presented in Duncan and
Peace (1966) and Soil and Material Engineers, Inc. (1982) indicates that
the Shelby plant is located near the contact between the mica schist and
gneiss complex, and the Toluca Quartz Monzonite. Thus, the facility may be
underlain by one or both rock units.
The Toluca Quartz Monzonite, along with the surrounding mica schists and
gneisses, weathers to saprolite--disintegrated rock that lies in its
original place, and retains the overall appearance, texture, and structure
of the bedrock. The residuum overlying the saprolitic layer is typically
finer grained near the surface and has a higher clay content because of
advanced weathering. The residuum typically becomes coarser grained with
increasing depth because of decreased weathering.
This weathering tends to bring about a convergence in the surface
appearance of the quartz monzonite, schist, and gneiss; making the most
thoroughly weathered rocks, despite differences in origin and original
composition, difficult to distinguish from one another in the field.
2.3 HYDROGEOLOGY
The groundwater reservoir in the Piedmont region, which includes Cleveland
County, has three components: (1) the clayey and sandy soil, (2) the
saprolite, and (3) the underlying bedrock. In the soil, water occurs
between the individual mineral grains. Thus, primary porosity and
permeability are important water-bearing properties of this unit.
Groundwater in the saprolite and underlying bedrock occurs in and along
secondary openings such as joints and fractures. In these units, secondary
porosity and permeability are also important.
In 1981, SME conducted a hydrogeologic study of the Shelby plant site. The
purpose of this study was to explore the shallow subsurface geology and
prepare a hydrogeological report addressing the rates and directions of

groundwater flow beneath the site. To provide data for this study, a
number of test borings were drilled in specific areas around the site.
Subsequent to drilling, the borings were converted to permanent groundwater
monitoring wells so that the effects of plant operations on the groundwater
system could be monitored.
At each well location, standard penetration tests were performed and
samples taken on 2.5-foot intervals for the first 10 feet, and 5-foot
intervals thereafter to the boring completion depth. These samples were
visually classified in the field by a geotechnical engineer/geologist.
Constant head infiltration tests were conducted at selected boreholes to
quantify the hydraulic conductivity of the soil.
Nine undisturbed samples were taken to test the in-situ and hydraulic
properties of the soils. Several laboratory tests were performed to
complete the assessment of the soil classifications made in the field and
quantify the hydraulic properties of these soils. Grain size distribution
tests were made in accordance with ASTM 0-422. Atterberg Limit tests were
performed in accordance with ASTM 0-423 and 0-424. Porosity determinations
were made on all of these samples. In addition, four of the undisturbed
samples were subjected to permeability tests in accordance with the
procedure outlined by the U.S. Army Corps of Engineers Manual EM
1110-2-1906.
Investigations conducted by Soil and Material Engineers, Inc. indicated
that a water-table aquifer occurs at the Shelby plant site in residual
soils and saprolite overlying bedrock. The depth to groundwater ranged
from 5 to 45 feet below ground surface with an average depth of about 20
feet. Bedrock depths ranged between 17 and 88 feet below ground surface at
the boring locations.
As shown on Figure 2-1, the main groundwater flow direction is eastward
from the topographic highest portion of the site. An eastward trending
groundwater divide then directs flows to the northeast and southeast. The
hydraulic gradients calculated by Soil and Material Engineers, Inc. (SME)
from November 1981 water level measurements ranged from about 0.010 to

0.030 foot per foot near the center of the groundwater divide to about
0.023 to 0.050 foot per foot toward the periphery of the main plant area.
Piezometric head differences were observed at 5 of the 6 locations where
well screens were set at two different depths. At locations where
differences were observed, the groundwater levels in the deep wells were
below water levels in the shallow wells, suggesting a downward hydraulic
gradient. However, SME indicates that the recorded potentiometric
differences may be caused by interbedded silt layers encountered in the
profile that act as a confining bed between the shallow and deep wells.
Using the available water-level data, porosity, and hydraulic conductivity
data, SME calculated average linear groundwater velocities of 18 feet per
year toward the southeast and 28 feet per year toward the northeast.
According to SME, the rate of flow in an eastward direction should be
within the range of 18 to 28 feet per year. Flow rates in a southward
direction were not calculated because of limited water-level data in the
area south of the plant.
Surficial drainage at the site is also generally eastward with flow
dividing to the northeast and southeast to intercept two unnamed
tributaries to Buffalo Creek that.flank the site. One tributary crosses
the northeast corner of the property. The other originates at the
recreational pond located on the south half of the property.
Buffalo Creek is located about 1.5 miles southeast of the site. It serves
as both the water supply for the plant and the WWTP receiving stream.
2.4 CLIMATE
Climatic data recorded at Shelby, North Carolina is summarized in Table
2-1. The annual average precipitation of 49.43 inches is fairly evenly
distributed throughout the year. Historically, March is the wettest month.
The fall months of September through December are somewhat drier than the
spring and summer months.

Over an annual period, average monthly temperatures range from a low of
39.2 degrees Fahrenheit in January to a high of 77.2 degrees Fahrenheit in
July. The warm summer temperatures combined with heavier precipitation in
these months serve to maintain a typically humid environment.
Winters are moderate with normal snowfall ranging from 0.1 inch in November

3.0 SITE INVESTIGATIONS
In addition to the hydrogeologic evaluation conducted by SME, a groundwater
sampling and analysis program, an electromagnetic survey, and test pit
excavations have been conducted at the Celanese Fibers Operations site.
The results of these investigations are described in this section.
3.1 MONITORING WELL INSTALLATION
In October 1981, SME installed 23 groundwater monitoring wells at the
Shelby plant. All 23 wells have 2-inch diameter PVC casings and 5-foot
well screens. The well locations are identified by the letters A through T
on Figure 3-1. Two wells, one shallow and one deep, were installed at
locations G, H, J, K, N, and R. In addition to a letter prefix, each of
the wells is also identified by a number representing the depth at the
bottom of the well screen.
During installation of the 23 groundwater monitoring wells, test borings
were drilled at 18 locations on the Shelby plant site. The general
subsurface conditions encountered in the area of contamination are depicted
by the geologic cross-sections indicated on Figure 3-2, and presented in
Figures 3-3 and 3-4.
Fill soils were encountered at boring sites G, K, and J, extending to
depths of 5 and 8 feet at G and K, respectively, and to depths of 12 and 24
feet at the two J boring locations. The fill at the G location is
associated with general structure or utilities construction at the plant
site; the fill at the K location is associated with the disposal of the GRU
sludge; and the fill at the J locations is associated with the former drum
storage area. Fill depths and consistencies in the vicinity of the former
drum storage area (near borings J-59.5 and J-28.5) are anticipated to vary
considerably and are dependent on the storage methods used.

Residuum occurs beneath the fill and at the ground surface in other areas
of the site. As shown on the geologic cross-sections (Figures 3-3 and
3-4), the site generally exhibits a typical Piedmont weathering profile.
The upper portion of the profile consists of stiff to very stiff sandy
silts ranging in depth from 7 to 42 feet at the locations penetrated.
Underlying, and occasionally interfingered with the sandy silts are medium
to fine, or coarse to fine sands. The sands generally have relative
densities ranging from loose to very firm. After the initial weathered
zone is penetrated, the samples are generally saprolitic; i.e. retain some
remnant or relict structure of the parent material.
Partially weathered rock (saprolite) was encountered at several of the test
boring locations. This material can be augered with a drill rig, but
exhibits standard penetration resistances in excess of 100 blows per foot.
The predominant soil constituents of partially weathered rock can be sands
or silts, depending on the mineral composition of the parent rock. Since
the weathered rock portions of the profile are perceived to have similar
hydrogeologic properties, partially weathered rock is depicted on the
geologic cross-sections as one unit, independent of the soil constituents.
Partially weathered rock was encountered in test borings G, H, J, K, M, N,
Q, and Rat depths of 80, 77, 47, 35, 31, 18, 22, and 40 feet,
respectively.
Auger refusal was encountered at borings T-17 and P-31.5, at depths of 17.5
feet and 32 feet, respectively. The rock was not cored, but these refusal
depths were interpreted by SME as the top of relatively sound, unweathered
rock rather than a boulder or rock lens in the weathered rock matrix.
Because the rock surface was not cored, information on the site bedrock
type(s) and characteristics is not known. However, during the grouting of
a 65-foot deep well near the B location, grout losses in excess of pumping
capacity occurred. At this location, the grout set-up at a depth of about
51 feet, indicating a fracture zone in the rock at about this depth.
Odors were noted at nine locations during drilling operations. A Oowtherm
odor was reported at boring F-55. Dowtherm is heat transfer fluid used in
plant processing operations. A Dowtherm odor was also noted at boring G-88

from the surface to a depth of 60 feet. At boring H-79.5, an organic odor
was noticed at a depth of 12 to 17 feet. At boring J-59.5, a carbide
odor was noted at a depth of 14 feet. Other chemical odors were noted at
depths of 24, 29, and 49 feet.
Odors were noticed at 8 to 22 feet and 42 to 60 feet in boring K-58. At
this boring, a silver oil-base substance was detected in auger cuttings
from below the water table. At boring M-44.5, a chemical odor was noted at
depths of 19, 24, and 29 feet. A faint odor that may have been ethylene
glycol was noted at 6, 9, 14, 24, and 29 feet in boring N-53.5. Odors were
noticed at all depths in boring 0-25. At boring R-42.5, a chemical odor
was noted at depths of 9, 14, and 19 feet.
Based on the results of the hydrogeologic evaluation conducted by SME
following well installation, wells A-39, B-34.5, C-49, and D-35 are
upgradient of the plant. As shown on Figure 1-2, wells F-55, G-50, and
G-88.5 are located in an unpaved process area where spills occurred. Well
H-79.5 is just west of the former drum storage landfill while wells J-28.5
and J-59.5 are within the boundaries of the former drum storage landfill.
Wells I-57.5, K-28, K-58, N-29, N-53.5, P-31.5, Q-33, R-17, R-42,5, S-50,
and T-17 form a downgradient network along the plant perimeter fence. Well
0-25 is located between the two emergency spill ponds and polishing pond
number 1. Well M-44.5 is adjacent to the two sludge holding ponds.
3.2 GROUNDWATER SAMPLING AND ANALYTICAL RESULTS
In November 1981, Celanese Fibers Operations began a groundwater sampling
and analysis program at their Shelby facility. Davis and Floyd, Inc. was
contracted to perform sampling and analysis. The program consists of
sampling background wells of possible concern on an approximately quarterly
basis with the other wells sampled at least annually. The initial list of
analytical parameters was chosen on the basis of their use as indicators of
possible contamination and their presence in materials used at the plant.

The initial analytical parameter list included:
• pH
• conductivity
• total organic carbon (TOC)
• total dissolved solids (TDS)
• oil and grease
• nitrate
• antimony
• total chromium
• copper
• zinc
Nitrate was included in this list because the plant is located in a rural
area where fertilizer use on surrounding agricultural lands may lead to
elevated nitrate levels in the groundwater system. Antimony is used as a
catalyst in plant processing operations. Chromium was used at the plant
until 1979. The analytical results of sampling conducted from November
1981 through November 1984 are contained in the Appendix.
During the first year of the program, samples were collected from all 23
wells on a quarterly basis. Table 3-1 summarizes the specific conductivity
and total organic carbon (TOC) results obtained at wells C-49, 0-35,
J-28.5, J-59.5, K-28, K-58, and 0-25. Data from well locations C and Dare
shown because these locations were identified by SME as being upgradient of
the plant and therefore indicative of background conditions. Specific
conductivity levels in these two wells range between 20 and 300 mmho/cm
with 100 lllllho/cm as the average. TDC levels range between 1.0 and 14 mg/1
with an average value of 6 mg/1. While these values provide a basis for
comparison with levels in other wells, the specific conductivity and TOC
parameters are still general measures of contamination that may not always
be proportional to the level of contamination present.
As shown in Table 3-1, the analytical results of four rounds of samples
from monitoring well 0-25 showed consistently elevated levels of specific
conductivity and total organic carbon (TOC). Specific conductivity levels

in wells J-28.5, J-59.5, and K-28 were higher than in wells C-49 and D-35,
but not as high as those in well 0-25.
On June 27, 1983, monitoring wells C-49, D-35, G-50, G-88.5, J-28.5,
J-59.5, K-28, K-58, 0-25, and R-17 were sampled. In addition, a GC scan
was performed on the sample from well 0-25. As shown in Table 3-1, a large
increase in both specific conductivity and TDC was observed at well K-28
during this sampling round. Well 0-25 continued to have elevated specific
conductivity and TDC levels. Well J-28.5 also showed high specific
conductivity. Thirteen priority pollutants were identified in the sample
from well 0-25 with the largest concentration identified as 2-chlorophenol
at 17 mg/1. Other compounds detected are listed on the analytical data
sheet included in the Appendix.
Table 3-1 shows that the same pattern of contamination in wells J-28.5,
K-28, 0-25 was detected in the six rounds of sampling data collected since
June 27, 1983. However, the TDC levels measured in well 0-25 have
decreased steadily since that time.
A priority pollutant analysis was performed on the May 18, 1984 sample from
well K-28. Five priority pollutants including benzene, methylene chloride,
toluene, phenol, and diethyl phthalate were found in the sample from well
K-28. In December 1984, samples were taken from wells D-35, K-28, 0-25,
and T-17 for GC/MS organic constituent analysis. Priority pollutants were
detected in all four wells. The types of compounds detected in wells K-28
and 0-25 did not correlate well with the constituents measured in previous
analyses. In fact, 2-chlorophenol, which had been present in well 0-25 at
a concentration of 17 mg/1 on June 27, 1983, was not detected in the
December 6, 1984 sample. Trichlorofluoromethane and zinc were detected in
all four of the December 1984 samples.
Although much of the focus of the analytical program has been on
contamination in wells K-28 and 0-25, trends in specific conductivity
levels have been noted at other wells. Measured specific conductivity
levels in wells P-31.5 and Q-33 have increased steadily since the beginning
of the sampling program. While no trend is evident, specific conductivity

readings in wells 8-34.5, G-50, R-42.5, S-50, and T-17 have consistently
been higher than the levels in wells C-49 and D-35. In no instance has an
attempt been made to correlate the observed contamination with a particular
source.
Nine additional monitoring wells were installed by SME in February 1985.
Because of a concern for contamination introduced from PVC casings, these
wells were constructed using stainless steel casing rather than PVC. Well
H-shallow extends about 15 feet below the water table adjacent to the
existing well H-79.5 which is drilled to the top of bedrock. SME installed
this well to provide data on the vertical hydraulic gradients existing in
this portion of the site, and provide water quality data to help identify
the source area for the elevated specific conductivity values at well
J-28.5 located topographically down-gradient.
Well 0-deep extends to the top of bedrock. According to SME, this well
will evaluate vertical gradients existing adjacent to polishing pond number
1, and will establish whether organic and inorganic degradation at well
0-25 has penetrated to deeper portions of the aquifer.
Wells U and V extend about 15 feet below the water table. Well U was
installed to provide local background data for conditions existing in the
wastewater treatment plant. SME installed well V to provide a better
understanding of the contamination indicated by well 0-25.
Well W was installed by SME to determine if the contamination observed in
well 0-25 has migrated around or below the polishing pond. Well X extends
about 15 ·feet below the water table and completes the perimeter well
network adjacent to polishing pond number 3.
A well nest was installed at location Y to evaluate groundwater quality
conditions in an area hydraulically downgradient from the glycol recovery
unit sludge burial area. The first round of samples from these wells was
collected in March 1985, but sample results are not yet available.

The North Carolina Division of Environmental Management's Asheville
Regional Office sampled two residential well water supplies on March 5,
1985. Both samples were analyzed for inorganics and organics. In one
sample, arsenic was detected at a level of 87 ug/1. In the other sample,
dimethyl hexene was measured at 52 ug/1.
3.3 ELECTROMAGNETIC SURVEY
In August 1983, SME performed an electromagnetic survey in three areas of
the Shelby plant site in an attempt to delineate areas containing elevated
specific conductivity levels in the groundwater and possible buried
materials. The results of this work were documented in the November 8,
1983 letter report entitled Electromagnetic Survey Report, Waste Treatment
Area, Shelby, North Carolina.
Areal is defined as the open area north of the wastewater treatment plant
and west of the emergency spill ponds. This was the area of primary
concern during the survey. Area 2 consists of the area immediately east of
polishing pond number l, and located between polishing ponds 2 and 3. Area
3 is the construction demolition landfill containing miscellaneous wastes
located north and west of the waste treatment plant area.
Figure 3-5 shows the results of the survey using 10-meter coil spacings
with a horizontal dipole orientation. This yields a theoretical
exploration depth range of 25 to 50 feet below ground surface. The lateral
zone of influence was about 33 feet on either side of the survey line. A
log transformation was used to convert the raw data measured in units of
millimhos per meter into dimensionless values representing the level
measured above background. These values are shown on Figure 3-5.
The most conspicuous trend shown on Figure 3-5 is a strong north/south
lineation in Area 1 located near the western edge of the aeration basins
and extending northward. Toward the fence line, the higher conductivity
values encompass a wider area in the east/west direction and trend

generally east toward borings K-28 and K-58. This area correlates
approximately with the location of the GRU sludge disposal area.
At the time of the electromagnetic survey, Area 2 was being used as a test
plot for the spray application of plant process wastes. The elevated
values observed in this area have been interpreted by SME as being related
to the spray application with some contribution from the adjacent polishing
ponds.
No prominent trends were noted in Area 3 except that the values
subs tan ti a 1 ly above background occur in the deeper fi 11 sections.
According to SME, measurements made in the vertical dipole orientation
indicate the probable presence of metallic objects within the landfill.
3.4 TEST PIT EXCAVATIONS
Based on the results of the electromagnetic survey, SME excavated three
test pits in February 1984 at the locations shown in Figure 3-5. The
results of their investigation are summarized in an April 3, 1984 letter
report entitled Summary of Findings and Suggested Future Work, _Wastewater
Treatment Plant Area, Shelby, North Carolina. Test pit TP-1 was excavated
at the height of the conductivity anomaly observed during the
electromagnetic survey, and in an area where the survey indicated buried
metal objects may exist. Test pits TP-2 and TP-3 were excavated north of
TP-1 in an area showing a lower conductivity anomaly, but not suspected to
contain buried metal objects.
Buried metal consisting of steel strapping, crushed drums, reinforcing
steel, pipe, and other debris was encountered in test pit TP-1. At a depth
of approximately 8 feet below land surface, free water entered the test
pit. This water and the underlying residuum was sampled. No unusual odors
were noted during the excavation.
Test pit TP-2 was excavated in an area suspected of containing GRU sludge.
An odorous reddish-brown and white material was encountered in this
excavation. Celanese Fibers Operations personnel identified the odor as

characteristic of GRU sludge and similar to that of water extracted from
wells at the K location. Free water was encountered at a depth of
approximately 2.5 feet. Samples of this water and the underlying residuum
were collected.
Conditions in test pit TP-3 were similar to those observed in test pit
TP-2, without encountering free water. A crushed drum was observed in the
test pit.

4.0 CURRENT SITUATION
4.1 SITE CHARACTERIZATION
A site characterization and data collection trip was conducted by USEPA and
CDM on April 3, 1985. USEPA personnel coordinated site activities with
Celanese Fibers Operations representatives and arranged access for CDM
personnel.
Prior to visiting the waste treatment area of the facility, a presentation
was given by Celanese Fibers Operations. The chronology of the site since
1970 was reviewed. A copy of all groundwater analyses from November 1981
through November 1984 was provided along with a monitoring well location
map.
Following the presentation, USEPA and CDM personnel were driven to the
waste treatment area. The old burning pit location is marked by a berm
just north of the aeration basins. The GRU sludge burial area is
grass-covered and clear of any above-ground material. The only waste
disposal area still in use is the sludge land application area which is
located on a hill northwest of the waste treatment area. This area was not
inspected during this trip.
On the day of the site visit there was very little liquid in either of the
emergency spill ponds. The ponds, which are unlined, receive liquid wastes
diverted from the WWTP because they would cause a process upset. In
addition, one of the clarifiers was completely empty. Both aeration basins
and all three polishing ponds were full.
The waste treatment area perimeter fence is bounded by trees to the north
and east. Looking south, several sheep were seen grazing in an open field
beyond the perimeter fence. According to Celanese Fibers Operations
personnel, there are approximately 47 private residence wells within a
one-quarter mile radius of the plant. The nearest downgradient wells are
located approximately 1300 feet southeast of the plant. In addition,

several wells are clustered northeast of the plant along Secondary Route
2210. The northeastern unnamed tributary to Buffalo Creek runs between the
plant and these wells. Several wells are also located on N.C. 198 opposite
the Celanese Fibers Operations Facility.
4.2 DEFICIENCIES IN EXISTING DATABASE
Currently there are insufficient data to conduct an analysis of
cost-effective remedial alternatives for the Celanese Fibers Operations
site. Listed below are the data gaps to be considered in the development
of subsequent remedial investigation activities.
• The areal extent and content of the waste disposal areas are not
well-defined. In order to evaluate remedial alternatives involving
material handling and transport, the volume and type of material
involved must be known.
, Because the waste disposal areas are not clearly defined, it is
difficult to attribute the observed groundwater contamination to a
particular source. For example, wells 0-25 and K-28 which have shown
the highest TDC and specific conductivity levels are located adjacent
to two potential contamination sources, the GRU sludge disposal area
and the emergency spill ponds. Furthermore, while specific
conductivity and TDC measurements can indicate a location where
groundwater contamination may be present, unless priority pollutant
analyses are done, the nature of the contamination will not be known.
• Specific conductivity and TDC measurements have other limitations,
particularly as indicators of background conditions. A full priority
pollutant scan at all the wells is recommended to establish baseline
conditions. From these results, an indicator compound can be
selected to track any future groundwater contaminant migration.
• There is little information regarding the geologic and hydraulic
characteristics of the aquifer system and the extent to which it is a
pathway for contaminant transport. To date, groundwater

contamination has only been observed in the shallow wells. The
recently installed wells will help better define the groundwater flow
pattern and provide data on vertical hydraulic gradients. In
addition, consideration should be given to pumping tests as a method
to develop aquifer transmissivity data.
• The recently installed wells have stainless steel casings rather than
the previously used PVC. The change was made because of a concern
for contamination introduced by the PVC material. As analytical
results are obtained from both types of wells, it may become apparent
that wells with stainless steel casings should be installed at other
locations.
