This section provides information on locations sampled during this and previous site sampling
investigations. Sampling data will be evaluated to determine whether additional site sampling
activities are needed and to complete the R1 report. Figures and tables referenced in this section
are provided at the end of this report. Figure 2-1 is a site location map; Figure 2-2 is a site layout
map.
2.1 Results of 2000 Expanded Site Inspection (ESI)
In March 2000, the North Carolina Superfund Section completed an expanded site inspection
(ES!) at the Sigmon's site (NCDENR, 2000a). During the ES!, nine groundwater samples
(including one duplicate), ten soil samples (including one duplicate), six surface water samples, and
six sediment samples were collected. Samples were analyzed for inorganics, volatile organics, and
extractable organics. One groundwater sample was collected from an onsite monitoring well;
remaining groundwater samples (including one duplicate) were collected from private wells,
including one private well that served as a background well. Three soil samples ( and one duplicate)
were collected from the lagoons at depths of! to 3 or I to 4 feet below land surface (bis). Two
soil samples were collected from the waste pile, at a depth of approximately one foot into the pile.
Two soil samples were collected as background surface and subsurface soil samples. The
remaining two soil samples were collected from the drainage ditch on both sides of the culvert
leading to the Davidson pond to determine attribution of contamination found in the pond. Two
surface water and sediment samples were collected from the Davidson pond: one from the
probable point of entry (PPE) into the pond and one upgradient of the discharge culvert from the
pond to the downgradient surface water pathway. One surface water and sediment sample was
collected at the PPE into the perennial stream located southwest of the site. Two surface water
and sediment samples were collected upstream of the PPE as attribution samples. One surface
water and sediment sample, collected from the West's pond, serves as a background sample.
Figure 2-3 shows sample locations.
The following constituents were detected in groundwater samples at concentrations either two times
greater than background levels or exceeding sample quantitation limits (SQ Ls): aluminum (8800
µg/L), arsenic ( 4.2J µg/L), barium (83 to 620 µg/L), chromium (86 µg/L), cobalt (1.2 to 39 µg/L),
iron(! 1000 µg/L), manganese (15 to 27000 µg/L), mercury(!. lJ to 6.6J µg/L), nickel (2.3 to 73
µg/L), I, 1-dicholoroethane (3 µg/L), 1,2-dichlorobenzene (8 µg/L), 1,3-dichlorobenzene (I µg/L),
1,4-dichlorobenzene (2 to 11 µg/L), acetone (SJ to 29J µg/L), benzene (2 µg/L), chlorobenzene
(72 µg/L ), chloroethane ( I µg/L ), cis-1,2-dichloroethene (3 µg/L ), and total xylenes (2 µg/L ).

During the ES!, surface water sample SST-023-SW was considered a background sample;
however, it was collected from a surface water pathway that potentially could be affected by the
site. The following constituents were detected in surface water samples at elevated concentrations
when compared to background sample SST-021-SW: aluminum ( 1900 µg!L ), arsenic (3.6J to I SJ
µg/L), barium (14 to 210 µg!L), cadmium (I to 1.2 µg!L), cobalt (4.8 to 14 µg!L), iron (740 to
7000 µg!L), lead (1.3 to4. l µg!L), manganese (35 to 1300 µg!L), nickel (4.3 to 11 µg!L), and zinc
(85 to 220 µg!L). The highest concentrations of these constituents were typically found in the
samples collected from the Davidson pond. Table 2-3 summarizes analytical results.
During the ES!, sediment sample SST-023-SD was considered a background sample; however,
it was collected from a surface water pathway that potentially could be affected by the site. The
following constituents were detected in sediment samples at elevated concentrations when
compared to background sample SST-021-SD: arsenic (8 mg/kg), barium (210 mg/kg), chromium
( 46 mg/kg), copper (3 7 J mg/kg), iron (3200 to 3 7000 mg/kg), manganese (280 to 3 80 mg/kg),
nickel (21 mg/kg), and zinc (150 mg/kg). Table 2-4 summarizes analytical results.
Table 2-4 includes two soil samples collected from the drainage ditch upgradient of the Davidson
pond. Although not detected above the SQ Ls of the background sediment sample, numerous
polycyclic aromatic hydrocarbons (P AHs) were detected in the Davidson pond. Many of these
constituents also were detected in the soil sample SST-018-SL collected in the drainage ditch
between the road and the pond, indicating that contamination in the pond may be attributable to
a source other than the site.
2.2 Field Investigation Activities and Sampling Locations: October 2002
The October 2002 RI sampling activities were conducted in accordance with the EPA
Environmental Investigations Standard Operating Procedures and Quality Assurance
Manual (EISOPQAM)(EPA, 1997) and addressed the following media:
• Groundwater
• Surface water
• Surface soil
• Subsurface soil
• Sediments
Specific activities performed in the field investigation included mobilization; utility locating;
groundwater monitor well installation; decontamination pad construction; groundwater, surface and
subsurface soil, surface water, and sediment sampling; investigation-derived waste (IDW) staging;
field and laboratory sample analyses; and surveying.

Figures 2-4 and 2-5 (soil sample and groundwater monitoring well installation locations,
respectively), and Figure 2-6 (Surface water and sediment sampling locations) show the sample
locations proposed in the Sampling and Analysis Plan (SAP) (Black & Veatch, 2002b ); Table
2-5 provides the rationale used in selecting these locations.
2.2.1 New Groundwater Monitoring Well Locations
The SAP called for installation of seven new monitoring wells during the first field sampling event
(Black & Veatch, 2002b ): three shallow surficial, three deep surficial, and one bedrock aquifer
well. These wells were planned to be screened at depths of30-40 feet, 70-80 feet, and I 00-110
bis, respectively.
During the field sampling event, water was not encountered at the planned shallow aquifer depths
due to extreme drought conditions. The following wells were not installed due to actual field
conditions: SS-MW-1 IA, SS-MW-1 IB, and SS-MW-13A. In addition, fractured bedrock was
encountered at the onsite monitoring well (SS-MW-11 C) location at a depth of30 feet bis versus
the planned depth of 110 feet bis.
Black & Veatch 's subcontractor, Miller Drilling Co., Inc., installed four new monitoring wells: two
deep surficial wells (SS-MW-12B, SS-MW-13B), one background shallow surficial well (SS-
MW-1 0A), and one bedrock aquifer well (SS-MW-11 C). Figure 2-7 shows actual monitoring
well locations.
2.2.2 Existing Monitoring Well Sampling Locations
One of two onsite existing monitoring wells were to be sampled. Both wells were dry due to
extreme drought conditions. Therefore, neither well was sampled.
2.2.3 Existing Private Potable Well Sampling Locations
Four private potable wells were planned to be sampled. One well (SS-PW-02) was dry and could
not be sampled. Five additional private potable wells were sampled at the request of the EPA
RPM. Figure 2-7 shows the locations of the sampled private potable wells.
2.2.4 Surface and Subsurface Soil Sampling
Twelve surface soil samples ( excluding QA/QC samples) and 28 subsurface soil samples/borings
( excluding QA/QC samples) were to be collected from 12 locations during the first field sampling
event. Due to the presence of trash and debris two boreholes (SS-SF/SB-10 and SS-SF/SB-11)
could not be collected. Six more subsurface soil locations (SS-SB-05, SS-SB4-06, SS-SB5-06,
SS-SB6-06, SS-SB7-06, and SS-SB3-09) were not sampled due to auger refusal. A borehole
(SS-SF/SB-13) was added at the SS-MW-11 C location to investigate the oily grains and pore
space noted during the drilling of the monitoring wells. A total of! I surface and 19 subsurface soil

Seven co-located surface water and sediment samples were to be collected to provide data for the
ecological risk assessment, establish upgradient background concentrations, examine surface water
to groundwater discharge, and determine the nature and extent of offsite contamination in these
media. All seven surface water and seven sediment samples were collected; Figure 2-9 shows
surface water and sediment sample locations.
2.2.6 Quality Assurance/Quality Control (QA/QC) Samples
As part of the sampling effort, QC samples were submitted to the EPA-designated CLP
laboratory, with field investigation samples, to evaluate confirmatory sampling procedures and
analytical methodologies. In general, field duplicate samples were collected at the rate of
approximately 5 percent of the regular samples; matrix spike and matrix spike duplicate samples
were collected at the rate of approximately 5 percent of the regular samples, or one per sample
delivery group per laboratory, whichever was appropriate. The RI report will provide sample logs
and chain of custody forms.
2.2. 7 Investigation-Derived Waste
Drill cuttings, surplus soils, well development, and purge water resulting from the well installation
process were containerized in U.S. Department ofTransportation (DOT)-approved 55-gallon
UNlA or I A-2 drums. Drill cuttings were placed in 55-gallon drums, which were then labeled
and staged for future characterization and disposal. The containers are onsite and will be disposed
of at a later date.

3.0 Data Reduction, Tabulation, and Evaluation
This section provides sample analytical results and other data collected during this field sampling
event. Figures and tables referenced in this section are provided at the end of this report.
3.1 Soil Boring Logs and Well Installation Diagrams
During the RI/FS investigation at the Sigmon's Septic Tank site, the Black & Veatch drilling
subcontractor, Miller Drilling Company, installed four monitoring wells and six soil borings. Soil
boring logs and well installation diagrams were generated using Geosystem® computer software
(Geosystem, 2000). Appendix A provides soil boring logs; Appendix B provides well installation
logs; Appendix C provides geologic cross-sections; and Appendix D provides well development
logs. The RI report will provide well installation diagrams.
3.1.1 Environmental and Lithology Soil Sample Collection from Boreholes
Soil samples were collected at locations SS-SB-01 through SS-SB-05 using decontaminated
stainless steel hand augers. Soil samples SS-SB-06, SS-SB-07,SS-SB-08,SS-SB-09,SS-SB-l 2,
and SS-SB-13 were collected using a hollow stem auger and 2-inch diameter split spoon. Soil
boring samples were analyzed for volatile organics (Modified SW-846 Method 5035 [using
Encore® T-handles and Encore® samplers and 82608-soil]); semi-volatile organics (Modified EPA
Method 625); pesticides/PCBs (Modified EPA Method 608); and metals (Modified EPA Method
200 series). In addition, soil samples SS-SB-01, SS-SB-04, and SS-SB-06 were analyzed for
dioxin (SW-846 Method 8290).
For lithologic samples, samplers were driven in intervals of2 feet, in accordance with American
Society for Testing and Materials ( ASTM) Standard Penetration Test D 1586. The effort required
to drive the sampler (blow counts) every 6 inches was recorded. Continuous split-spoon soil
samples were collected from approximately 2 to 4 feet bis, 5 to 7 feet bis, and every 5 feet
thereafter. Each soil sample was visually logged by the site geologist for soil classification, color,
grain size, moisture, texture, consistency, and geologic characteristics using a modified version of
the Unified Soil Classification (USC) system.

The Black & Veatch surveying subcontractor, Donaldson, Garrett & Associates, Inc., conducted
a topographic survey of the site. They also surveyed two existing onsite monitoring wells, the four
newly installed monitoring wells, seven private potable wells, and all surface soil, subsurface soil,
sediment, and surface water samples collected during this sampling event.
Soil and surface water/sediment surveys included northings, eastings, and elevations. Monitoring
well surveys included northings, eastings, top of casing, top of riser, and top of ground. Potable
wells surveys included northings, eastings, top of riser, and top of ground.
Horizontal coordinates are referenced to the North Carolina Grid System, North America
Datum of 1983 (NAD 83). Elevations are shown in feet above mean sea level, National
Geodetic Vertical Datum of 1929 (NOVO 29) (Donaldson, Garrett & Associates, 2002).
Appendix E provides survey maps.
3.3 Field Data
Field data associated with the RI investigation includes soil boring and well installation diagrams,
geologic cross sections of site lithology, groundwater field parameters, water levels, and slug testing
data. Section 3.1 addresses data reduction associated with soil boring logs. The following sections
detail data reduction and tabulation of the other field data.
3.3.1 Groundwater Field Parameters
Groundwater samples from the monitoring wells were analyzed for the following field parameters:
temperature,dissolved oxygen, conductivity, redox potential, pH, and turbidity; Table 3-1 provides
analytical results. 0 2 lower explosive limit (LEL) and organic vapor analyzer (OVA)
measurements were collected at each well installation location.
3.3.2 Water Levels
Groundwater levels and total depths of the four newly installed wells were measured before
development, during development, and before groundwater sampling. Groundwater levels were
obtained for seven potable water wells. For pre-sampling measurements, after unlocking the

the presence of organic vapors. A decontaminated electric water level indicator then was placed
into the monitoring well to measure the depth to the static water level and total well depth. Depths
were recorded to the nearest 0.01 foot and measured from a reference notch at the top of the
monitoring well casing; Table 3-2 provides results. Figure 3-1 is a potentiometric surface map
showing water table elevations.
3.3.3 Slug Testing .
Slug testing of monitoring wells was not performed during this sampling event. If necessary, slug
tests will be performed at a later event to estimate hydraulic conductivity of the strata where wells
are screened.
3.4 Analytical Data
This subsection summarizes analytical data derived from the RI field investigation.
3.4. 1 RI Analytical Data and Data Qualifiers
In the tables presented, some concentrations of organic and inorganic constituents may have been
assigned a "J" qualifier, indicating that the qualitative analysis was acceptable, but the quantitative
value is an estimate. Other constituents may have been assigned an "N" qualifier, indicating that
they were detected based on the presumptive evidence of their presence. This means that the
compound is only tentatively identified, and its detection cannot be a positive indication of its
presence. Some sample results are assigned a "U" qualifier, which indicates that the constituents
were analyzed for, but not detected above the sample quantitation limit (SQL) for that sample. The
reported number is the laboratory derived SQL for the constituent. At times, miscellaneous organic
compounds that do not appear on the target compound list are reported with a data set. These
compounds are assigned a "JN" qualifier, indicating that they are tentatively identified at estimated
quantities. Because these compounds are not routinely analyzed for, background levels or SQL
levels are not generally available for comparison. Data assigned an "R" qualifier are not useable
data. Samples containing concentrations of contaminants greater than groundwater performance
standards are considered to be elevated.

This section provides information on the usability of sample analytical data and field data
generated during the RI field investigation for the Sigmon's Septic Tank site. The data
usability report evaluates the quality of the data and the implication of a qualifier applied
to the sample result. The EPA Region 4 Science and Ecosystem Support Division
(SESD) applies qualifiers to sample results in accordance with criteria and parameters
listed in the United States Environmental Protection Agency Contract Laboratory
Program National Functional Guidelines for Organic Data Review (EPA, 1994a),

4.1.2 Field Data
Field data recorded for use in RI/FS project reports consist of the following items:
boring logs and well installation diagrams for monitoring wells installed during the RJ,
groundwater field parameters recorded before groundwater sample collection,
groundwater levels, slug testing data recorded with a data logger, and surveying data.
The following subsections present detailed information about each of these types of field
data.
4.1.2.1 Boring Logs and Well Installation Diagrams. During the RJ/FS
investigation at the Sigmon's Septic Tank site, the Black & Veatch drilling
subcontractor, Miller Drilling Company, installed four monitoring wells and six soil
borings. Soil boring logs and well installation diagrams were generated using
Geosystem® computer software (Geosystem, 2000). The pertinent information required to
evaluate the usability of boring logs and well installation diagrams has been reviewed
and determined to be of sufficient quality and deemed acceptable for their intended use.
4.1.2.2 Groundwater Field Parameters. Groundwater samples were also analyzed
for the following field parameters: temperature, dissolved oxygen, conductivity, redox
potential, pH, and turbidity; Table 3-1 provides analytical results. LEL and OVA
measurements were collected at each well installation location.
Groundwater field parameter data were collected from well development logs and field
logbooks. Data were tabulated, reviewed, and approved as tabulated, in terms of

properly transcribing the data. Temperature, dissolved oxygen, conductivity, pH,
turbidity, and redox potential data are considered to be of sufficient quality and have
been deemed acceptable for their intended use.
Despite slow purge rates, SS-MW-I0B was evacuated during purging. Sample SS-MW-
1 OB was collected following sufficient recovery of the well, in accordance with the US.
EPA Environmental Services Division, Environmental Investigations Standard Operating
Procedures and Quality Assurance Manual (EISOPQAM) (EPA, 1997). The-minimum
goal of IO NTUs was not met upon well recovery. Temperature, redox potential,
dissolved oxygen, conductivity, pH, and turbidity were measured during sample
collection from the recovered volume, as the measurements of record for the sample.
Dissolved oxygen data are questionable because readings were recorded from
groundwater samples brought to the surface. EISOPQAM recommends collecting
dissolved oxygen in situ using a field probe or measuring from a stoppered BOD bottle
(EPA, 1997). The U.S. Geological Survey (USGS), however, recommends that dissolved
oxygen measurements should occur in an open or flow-through chamber, with the
pumped groundwater flowing over the ends of the probe (USGS, 1999). Therefore,
dissolved oxygen data from this round of groundwater samples will be included in this
report, but will not be evaluated in the future RI report.
4.1.2.3 Surface Water Field Parameters. Surface water field parameters were not
collected during this sampling event.
4.1.2.4 Groundwater Levels. Groundwater levels and total depths of the four newly-
installed wells were measured before development, during development, and before
groundwater sampling. Groundwater levels of seven potable water wells were measured.
For pre-sampling measurements, after unlocking the monitoring well and removing the
cap, the ambient air was monitored using an OVA to evaluate the presence of organic
vapors. A decontaminated electric water level indicator then was placed into the
monitoring well to measure the depth to the static water level and total well depth.
Depths were recorded to the nearest 0.01 foot and measured from a reference notch at the
top of the monitoring well casing. Table 3-2 provides the analytical results. Data are

seven private potable wells; and all surface soil, subsurface soil, sediment, and surface
water samples collected during this sampling event. (Donaldson, Garrett & Associates,
2002).
Soil and surface water/sediment surveys included northings, eastings, and elevations.
Monitoring well surveys included northings, eastings, top of casing, top of riser, and top
of ground. Potable well surveys included northings, eastings, top of riser, and top of
ground. Horizontal coordinates are referenced to the North Carolina Grid System, North
America Datum of 1983 (N AD 83 ). Elevations are shown in feet above mean sea level
by the National Geodetic Vertical Datum of 1929 (NGVD 29). Appendix E provides the
survey maps.
Survey data is considered to be of sufficient quality and have been deemed acceptable for
its intended use.
