3.0 STUDY AREA INVESTIGATION
3.1 Site Characterization Field Activities
•
Field work for the Macon/Dockery site RI was conducted in two phases. Phase I RI field
investigations were conducted from September 1989 to January 1990 and included the
development of a site base map, source area characterization activities, an initial
hydrogeologic assessment, an inventory of off-site wells, and the collection of surface
soil, ground-water, surface water, and sediment samples. Phase II RI field investigations
were conducted from July 1990 to October 1990 and consisted of additional source area
characterization activities, monitoring well installation and ground-water sampling,
hydraulic testing of monitoring wells, and sampling of off-site wells. As outlined in the
approved Work Plan, environmental samples collected during Phase I of the RI were
submitted for analysis of Target Compound List (TCL) and Target Analy1e List (TAL)
parameters (Table 3-1). Results of the Phase I RI analyses were subsequently used to
develop an approved list of site indicator parameters (Table 3-2) for Phase II RI sample
analyses. Chemical analyses of most samples collected during the Phase II RI included
the complete list of Acid Extractable Compounds even though only pentachlorophenol
was required. Theses additional analyses were mistakenly performed by the analy1ical
laboratory. Even though these analyses were not required, they are included in this
report for completeness.
Unique identification numbers were developed which signify the sample type and sample
location. Each sample identification consists of the Sirrine job number, a sample type
code, a sample location number, and a sample replicate number. Sample type codes
used during this investigation were as follows:

Phase II RI well installation activities were conducted in two stages. Drilling and well
installation services wells for both stages were provided by Groundwater Protection, Inc.
and were conducted under the direction of Sirrine field personnel. U.S. EPA oversight
personnel were also on site during both periods to observe well installation activities.
Decontamination and installation procedures for Phase II RI monitoring wells were
conducted in accordance with Sections 2.7.1 and 2.7.5 of the POP and/or subsequent
agreements with U.S. EPA.
As noted below, Phase II RI monitoring wells were predominantly installed by the hollow
stem auger method. The success of this method during this portion of the RI, as
opposed to Phase I, can probably be attributed to either the use of smaller diameter
augers (4.25-inch I.D. verses 6.25-inch I.D.) as well as the use of larger and/or more
powerful drill rigs.
The first stage of well installation under Phase II began on July 18, 1990 and was
completed on August 10, 1990. During this period, nine stainless steel monitoring wells
(MW-02A, MW-05, MW-06, MW-07, MW-08, MW-OBA, MW-09, MW-13, and MW-14R) and
one PVC piezometer (P-11 A) were installed at the Macon site (Figure 3-12). Two
stainless steel monitoring wells (MW-15 and MW-16) were also installed at the Dockery
site at this time (Figure 3-13). The objective of this effort was to complete the
assessment of site ground-water quality and hydrogeology in accordance with the Work
Plan and the POP.
The second well installation stage was conducted from October 8 to October 12, 1990.
During this period, three stainless steel monitoring wells (MW-15A, MW-18, and MW-20)
were installed at the Dockery site (Figure 3-13). Work completed during this effort was

5.0 NATURE AND EXTENT OF RESIDUAL CHEMICALS
•
Data collected from Phases I, 11, and IIA of the RI have been combined, validated, and
presented in accordance with the guidelines presented in Risk Assessment Guidance for
Superfund; Volume I (U.S. EPA, 1989). The RI data have been sorted by medium,
analytical fraction, and in appropriate cases, by geographic area. Data summary tables
have been compiled for analytical results of all samples showing detected
concentrations. Each data summary table includes only those parameters which were
detected in at least one of the samples which are included on that table. Copies of the
original analytical data sheets are included in Appendix J.
The data summary tables have been screened to identify U.S. EPA-defined laboratory
contaminants/artifacts. Those values verified as laboratory contaminants have been
flagged and will not be used in further data evaluations. In addition, some results
contain common laboratory contaminants without those compounds being present in
their accompanying blank(s). These results will be carried forward in the data evaluation
process but should be viewed with some skepticism. As defined in the Contract
Laboratory Program Statement of Work for Organics Analysis (U.S. EPA, 1988), acetone,
methylene chloride, toluene, and the phthalate esters are considered by U.S. EPA to be
common laboratory contaminants. These compounds have been checked in the
analytical results herein by comparing their concentrations with those in their associated
blank samples to determine whether the compounds should be considered as laboratory
contaminants or residual site chemicals. In accordance with the Risk Assessment
Guidance for Superfund: Volume 1 -(U.S. EPA, 1989), the following definition was used
to determine the validity of the presence of the constituent. If the sample blank contains
detectable levels of common laboratory contaminants, then the sample results should be
considered as positive results only if the concentrations in the sample exceed ten times
the maximum amount detected in any blank.

As indicated in the analytical data packages (Appendix J), a portion of the samples
submitted for analysis required either dilution or re-extraction to bring the concentration
of various volatile or semivolatile organic analytes within the instrument calibration range.
Two sets of volatile and semivolatile organics analysis data sheets are therefore provided
in Appendix J for each sample that required either dilution or re-extraction. Diluted
samples are indicated by a "Dl" suffix appended to the sample identification. Similarly,
re-extracted samples are indicated by a "RE" suffix appended to the sample identification.
Merging of the two data sets for the above samples was required in order to enhance
the utility of the data summary tables presented in this section. Data sets were merged
by identifying volatile and semivolatile compounds marked with a "E" data flag.
Concentration values marked with an "E" data flag were then replaced with the
corresponding concentration values for the diluted or re-extracted samples. All other
concentration values listed in the data summary tables (i.g., values which did not exceed
the calibration range of the instrument) are as reported in the pre-dilution or pre-re-
extraction organics data analysis sheets.

Soil Boring Samples -Upper Macon Site
•
Chemical analyses of 18 soil boring samples collected from the Upper Macon site
detected the presence of 37 different TCL constituents (Table 5-9). As summarized
below, these constituents include four acid extractable compounds, 19 base/neutral
extractable compounds, and 14 volatile organic compounds. Soil boring samples were
also collected at two control locations (9168-SB13-01-1 and 9168-SB14-01-1).
Detected acid extractable compounds include 2,4,5-trichlorophenol, 4-methylphenol,
benzoic acid, and phenol. These constituents were detected in six samples and
range in concentration from 39 ug/kg (4-methylphenol in 9168-SB09-01-1) to 3000 ug/kg
(phenol in 9168-SB07-01-1) .
Detected base/neutral extractable compounds comprise two chemical groups: phthalate
esters, and polyaromatic hydrocarbons. Detected phthalate esters include bis(2-
ethylhexyl) phthalate, butyl benzyl phthalate, di-n-butylphthalate, and di-n-octyl phthalate.
Bis(2-ethlhexyl) phthalate was detected in nine Upper Macon site soil boring samples at
concentrations ranging from 87 ug/kg (9168-SB02-02-1) to 920 ug/kg (9168-SB09-01-1).
Butyl benzyl phthalate was only detected in sample 9168-SB07-01-1 at a estimated
concentration of 1100 ug/kg. Di-n-butyl phthalate was detected in two samples at
estimated concentrations of 52 ug/kg (9168-SB-06-01-1) and 180 ug/kg {9168-SB07-01-
1). Di-n-octyl phthalate was detected in one sample at a concentration of 460 ug/kg
(9168-SB08-01-1 ). A summary of detected TCL constituents is presented in Table 5-10.
TAL inorganic constituents detected among the above 18 soil boring samples include 19
metals (Table 5-11). Table 5-12 summarizes detected TAL constituents for Upper Macon

Soil Boring Samples -Lower Macon Site
•
Four soil boring samples and one duplicate sample were collected from the Lower
Macon site and analyzed. Twenty-six different TCL constituents were detected (Table 5-
13). These constituents include one acid extractable compound, 20 base/neutral
compounds, and five volatile organic compounds.
Benzoic acid is the sole acid extractable detected. Sample 9168-SB11-01-1 contained
an estimated concentration of 160 ug/kg.
The detected base/neutral extractable compounds comprise two chemical groups:
phthalate esters and polyaromatic hydrocarbons. Detected phthalate esters include
bis(2-ethylhexyl)phthalate, di-n-butyl phthalate, and di-n-octyl phthalate. Bis(2-ethylhexyl)
phthalate was detected in two Lower Macon site samples in estimated concentrations
ranging from 53 ug/kg (9168-SB11-02-2) 66 ug/kg (9168-SB11-01-1). Di-n-butylphthalate
and di-n-octyl phthalate were only detected in sample 9168-SB11-01-1 at estimated
concentrations of 43 ug/kg and 190 ug/kg, respectively.
PAHs were detected in only three Lower Macon site samples (9168-SB11-01-1, 9168-
SB11-01-1, and 9168-SB11-02-2). Detected PAHs include 2-methylnapthalene,
acenaphthene, acenaphthylene, anthracene, benzo(a)anthracene, benzo(a)pyrene,
benzo(b)fiuoranthene, benzo(g,h,i)perylene, benzo(k)fluoranthene, chrysene,
dibenzo(a,h)anthracene, fluoranthene, fluorene, indeno(1,2,3-cd)pyrene, naphthalene,

Detected base/neutral extractable compounds include bis (2-ethylhexyl) phthalate and di-
n-octyl phthalate. Bis(2-ethylhexyl) phthalate was detected in four samples and ranged
in concentration from 51 ug/kg (9168-MW0B-4S-1) to 110 ug/kg (9168-MW-09-4S-1 and
9168-MW12-4S-1). Di-n-octyl phthalate was detected in two samples at estimated
concentrations of 60 ug/kg (9168-MW0B-4S-2) and 62 ug/kg (9168-MW0B-4S-1).
Detected volatile organic compounds include 2-butanone, acetone, and methylene
chloride. Maximum detected concentrations range from 9 ug/kg (2-butanone in 9168-
MW0B-48-1) to 140 ug/kg (acetone in 9168-MW05-4S-1) to 55 ug/kg (methylene chloride
in 9168-MW05-4S-1). Acetone was determined to be a laboratory contaminant in
samples 9168-MW13-7S-1 and 9168-MW14-2S-1. Methylene chloride was determined to
be a laboratory contaminant in all MW-12 samples, 9168-MW13-7S-1, and 9168-MW14-
2S-1. Detected TCL constituents are summarized in Table 5-26.
TAL constituents detected include 20 metals (Table 5-27). Table 5-28 summarizes
detected TAL constituents for Macon site vadose zone soils. Comparison of detected
TAL constituents in the Macon site vadose zone soils against the control locations
(9168-SB13-01-1 and 9168-SB14-01-1) indicates that the concentrations of inorganic
constituents in vadose zone soils are generally present at higher levels than the ·control
locations.

compound, four base/neutral extractable compounds, and five volatile organic
compounds (Table 5-29}.
The detected acid extractable compound is 2-methylphenol (97 ug/kg in 9168-MW15-2S-
1 }. Detected base/neutral extractable compounds include bis (2-ethylhexyl) phthalate, di-
n-butyl phthalate, dimethyl phthalate, and dimethyl phthalate. Detected concentrations
range from 42 ug/kg (di-n-butyl phthalate in 9168-MW15-4S-1} to 9500 ug/kg (dimethyl
phthalate in 9168-MW15-2S-1}.
Detected volatile organic compounds include 2-butanone, 2-hexanone, 4-methyl-2-
pentanone, acetone, and methylene chloride. Detected concentrations range from 1.0
ug/kg (2-hexanone in 9168-MW15-2S-1) to 9200 ug/kg (acetone in 9168-MW15-4S-1}.
Methylene chloride was determined to be a laboratory contaminant in 9168-MW16-2S-1.
Detected TCL constituents are summarized in Table 5-30.
TAL constituents detected include 15 metals (Table 5-31). Table 5-32 summarizes TAL
detections for Dockery site vadose zone soil samples. Comparison of detected TAL
constituents in Dockery site vadose zone soils against the control locations (9168-SB 13-
01-1 and 9168-SB 14-01-1) indicates that the concentrations of inorganic constituents
detected in monitoring well soil boring samples 9168-MW15-4S-1 and 9168-MW18-1S-1
are generally present at higher levels than the control locations.

exist that affect the rate at which residual chemicals reach the water table and are
transported in the saturated zone. Some of the mechanisms that reduce the advance of
chemicals in the subsurface include adsorption-desorption, biodegradation, ion exchange
reactions, reduction reactions, and diffusion of materials into immobile water or pore
zones. Often, where organic chemicals are likely to be transported through the soil
media, adsorption reactions occur that transfer contaminant mass from the pore water to
the solid matrix of the porous medium. This is likely a significant mechanism for
reducing the mobility of residual chemicals within the saturated zone.
In general, ground-water samples which contain TAL metals at concentrations
significantly above those reported for the control sample and for EPA primary and
secondary Maximum Concentration Limits (MCLs) were collected from monitoring wells
MW-5, MW-6, MW-7, MW-8, MW-SA, MW-9, MW-10, and MW-19. Barium, chromium,
iron and manganese were the TAL constituents detected that primarily exceeded MCLs.
Aluminum, beryllium, calcium, cobalt, magnesium, nickel, and vanadium were
consistently detected at concentrations exceeding those detected in the control sample.
A number of these metals (sodium, calcium, magnesium, and manganese) are common
metals in native geologic materials and are reported by Dragun (1988) to exist in
relatively high concentrations in ground water. When compared to these natural
concentrations, it appears that aluminum, barium, beryllium, chromium, cobalt, copper,
iron, lead, nickel, and vanadium are the primary TAL metals at the Upper Macon site of
concern in terms of potential impact to the environment. Significant concentrations of
suspended sediment in many of the ground-water samples may have biased the
apparent TAL metals concentrations .

5.3.3.2 Lower Macon Site. Analytical data for Lower Macon site monitoring wells
indicate the presence of residual TCL constituents. As with the majority of Upper Macon
site wells, the presence of residual chemicals in wells MW-4, MW-12, MW-13, and MW-
14R appears to be related to the presence and close proximity of former waste disposal
source areas, primarily lagoons. These wells are located directly down-gradient of
lagoon areas and serve as direct monitoring positions for residual chemicals migrating to
the northwest in ground water. As with the Upper Macon site, there is no indication of
widespread distribution or plumes of impacted ground water at the Lower Macon site
(Figure 5-1). Elevated concentrations of TAL metals were detected in all lower Macon
site wells. Similar to the Upper Macon site, aluminum, barium, beryllium, chromium,
cobalt, iron, lead, nickel, and vanadium appear to be the metals of primary concern.
Also, the high turbidity in many of the ground-water samples may have biased the
• apparent TAL metals concentrations.
•
5.3.3.3 Upper Dockery Site. Elevated concentrations of TCL constituents at the upper
Dockery site appear to be related to previous drum handling activities at the site.
Ground-water samples collected from monitoring well MW-15 indicate relatively high
concentrations of residual chemicals, especially 1, 1, 1-trichloroethane, 1, 1-dichloroethane,
and 1, 1-dichloroethene (Figure 5.2). Review of aerial photographs of the site and visual
observations during RI field activities indicate that the vicinity of MW-15 was used for
drum handling, storage, and possibly disposal operations. Due to the trace
concentrations of residual chemicals in other Upper Dockery site wells, there is no
indication of widespread impact to site ground-water; rather, the impact appears
localized in the immediate area of MW-15 (Figure 5-2). Elevated TAL metals were also
detected in MW-15. Aluminum, chromium, cobalt, iron, nickel, and vanadium exceed
commonly reported levels for naturally occurring metals in ground water and certain

MCLs (chromium and iron). As stated earlier, the high sample turbidity may have biased
the apparent TAL metals concentrations.
5.3.3.4 Lower Dockery Site. The presence of residual chemicals (TCL and TAL
constituents) in MW-16 (Lower Dockery site) appears to be related to the close proximity
of the well to Lagoon 12. MW-16 is located immediately down-gradient of Lagoon 12
and serves as a direct monitoring position for ground water migrating away from the
lagoon (Figure 4-3 and Figure 5-2). However, as noted earlier, TAL metals
concentrations may be biased due to the high turbidity levels.
5.3.3.5 Private Wells. Analytical results from ground-water samples collected from
privately-owned wells in the area detected no TCL constituents in ground water in these
wells. Detected TAL constituents for wells PW-02 and PW-03 are within MCLs and
ranges determined from the control sample. In well PW-04, iron exceeds the secondary
MCL (483 ug/I versus an MCL of 300 ug/L) and is less than the concentration detected
in the control sample. Vanadium and zinc were detected in concentrations slightly
exceeding the control sample. Detected concentrations in well PW-05 exceed MCLs for
iron and manganese. However, these constituents were detected in concentrations less
than the control sample. Cobalt, copper, magnesium, vanadium, and zinc
concentrations in PW-05 exceed concentrations detected in the control sample for those
metals. PW-05 is located at a slaughterhouse facility. Observed site operations and
conditions indicate that impact to the soil and ground-water media are very likely due to
the slaughtering operations, cleaning practices, and disposal procedures.

5.3.4 Surface Water
•
No residual TCL constituents were detected in surface water samples collected down-
gradient from either the Macon site or the Dockery site. TAL constituents detected in
the Macon site surface water control sample (9168-SW-03-1) are within normal ranges
for natural waters and, excepting iron, concentrations of metals are below MCLs. The
remaining stream sample (9186-SW-02-1) compares closely to the control sample with
the exception of iron and manganese. The surface water sample collected from the
Lower Macon site pond contains elevated concentrations of barium, chromium, iron,
lead, and manganese. Mercury was also detected but at low concentration. The
variability of detected concentrations of T AL constituents in the surface water samples
likely reflects differences in the amount of suspended sediment included with the
samples.
The surface water samples collected downgradient of the Dockery site compare
favorably to the control sample. Cobalt was detected in samples 9168-SW-05-1 and
9168-SW-06-1 but not in the control sample. However, the low concentration of
detected cobalt is considered natural in occurrence.
The Macon site pond is a relatively closed system with no significant outflow. As such,
the pond has a high concentration of suspended sediment which can significantly bias
the total metals analyses. The Phase I pond sample (SW-01) was collected immediately
after the bottom sediments were disturbed. Samples from Phase II (SW-11, SW-12)
were collected with less disturbance and the resultant analyses indicated much lower
concentrations. Further, a split of the Phase II sample was filtered in the field to further
reduce the influence of suspended sediments. This sample had even lower values for

detected metals than did the un-filtered, relatively un-disturbed sample. Based upon a
comparison of these results, the detectable metals concentrations primarily represent the
physical setting of the pond rather than the concentration of soluble metals
concentrations.
5.3.5 Sediment
Residual TCL constituents detected in the Macon site control sediment sample are
related to the presence of tar or asphalt-coated wood fragments unavoidably collected in
the sediment sample. TCL constituents were not detected in other downstream
sediment samples.
The presence of acetone in the Macon pond sample {200 ug/kg) is likely due to
laboratory contamination. Acetone was not detected in the surface water collected from
this pond. Additionally, the only other organic compounds detected In the pond
sediment sample, methylene chloride and chloroform, both appear to be laboratory
artifacts.
Sediment samples from the Dockery site indicate the presence of benzoic acid and
benzo {a) pyrene. Due to the remote nature of sampling location 9168-SED-04-1, it
appears that the presence of these constituents may be naturally derived {Merck Index,
1983),
As with surface water samples, the pond sediment samples exhibit elevated metals
concentrations, specifically barium, chromium, cobalt, manganese, vanadium, and zinc.
Variations in metals concentrations detected in stream sediment samples are viewed as

a function of sediment grain size, mineralogy, and depositional environment. Analytical
and physical data indicate that stream sediment transport is not acting as a mechanism
for the off-site transport of TAL constituents. This indication is supported by the fact that
none of the sediment samples that exhibit elevated metals concentrations reflect a
corresponding increase in the concentration of organic constituents.
5.3.6 Discussion
In summary, no widespread or uniform vertical or horizontal distribution of the residual
chemicals present at the site is apparent. Instead, chemical residuals appear to be
primarily concentrated, both in soil and ground water, in localized areas related to former
direct disposal activities (lagoon and/or drum handling and storage). Due to the lack of
steep topography, the heavy vegetative cover at the site, and the nature of residual
chemicals at the site, it is not likely that overland migration of residual chemicals or
impacted surface soils away from the former disposal areas is significant. Significant
transport of impacted ground water also appears to be confined. Further discussion of
ground-water transport will be provided in Section 6.0 .

restricted to the former waste oil lagoons and drum storage areas. This assumption is
supported by observations made during test pit excavation and soil boring activities,
findings of the geophysical survey, and results of the surface soil sampling program.
The model further assumes that the primary mechanism by which residual chemicals
were introduced into the unsaturated zone was by the seepage of waste materials
through the bottom of the unlined lagoons or by the release of waste materials from
drums to surface soils.
Following a release of waste materials to the subsurface, infiltration from precipitation is
believed to mobilize residual chemicals present in soils at the source areas and transport
the compounds downward. As depicted in the conceptual model, residual chemicals
mobilized by wetting fronts are initially transported to the perched water table. Due to its
limited lateral extent, however, this unit is not anticipated to serve as a primary ground-·
water migration pathway for the residual chemicals. Instead, constituents are believed
continue to move vertically downward until reaching the water table in the saprolite.
Upon reaching the water table the residual chemicals are anticipated to move
horizontally in the direction of ground-water flow which, at both Macon and Dockery
sites, is to the west-northwest. Residual chemicals in the saprolite, therefore, are
expected to be transported in a west-northwestern direction from the source areas
towards the low-lying marshes formed by Solomon's Creek or to the Pee Dee River as
the ultimate point of discharge. Similarly, residual chemicals present in the bedrock, if
any, are anticipated to be transported in a west-northwestern direction from the source
areas towards the low-lying marshes of Solomon's Creek or to the Pee Dee River as the
final point of discharge.

Generally, compounds with a high water solubility are more likely to biodegrade, while
compounds with a low water solubility are less likely to biodegrade. Thus, compounds
with a low water solubility tend to be more persistent in the environment, though
compounds with a higher water solubility are more likely to move greater distances in
the subsurface.
Other fate processes that are, or can be, affected by water solubility include hydrolysis
and oxidation. These factors affect the degradation and transportation of chemical
compounds, and therefore influence the persistence of a chemical compound in the
subsurface environment.
Compounds detected at the Macon/Dockery site include semi-volatile organic
compounds and volatile organic compounds. The semi-volatile organic compounds
generally have lower water solubilities as compared to the volatile organic compounds
(Table 6-1). The semi-volatile compounds also have higher Koc values than the volatile
organic compounds. Thus, the semi-volatile compounds generally tend to be adsorbed
onto the soil and aquifer materials rather than be dissolved into soil water and ground
water.
Generalizations can be made regarding the distribution of residual chemicals at the
Macon/Dockery site. Semi-volatile organic compounds were detected in ground water
samples from a limited number of monitoring wells close to the residual chemical source
areas. Volatile organic compounds were detected in monitoring wells at greater
distances from the residual chemical source areas.

and effective porosity (Appendix K) were underestimated to yield a conservative estimate
of the maximum extent of the residual chemical plume. The actual field porosity, as
calculated from void ratio data, averages approximately 0.5 (see Appendix K). The
effective porosity is therefore not expected to be less than 0.3. In the model calculation,
however, an effective porosity of 0.2 was used, giving a conservative estimate of the
linear velocity. A lower value of actual porosity, 0.4, was again selected as a
conservative value. A lower effective porosity would increase the linear velocity which,
in turn, would transport the residual chemicals a greater distance. Bulk density of the
aquifer materials was assumed to be 1.5 g/cm3.
As indicated in Table 6-2, a low distribution coefficient was applied to the model to
account for two factors. First, 1, 1, 1-trichloroethane and trichloroethane are the parent
compounds most commonly detected at the site and occur generally at the highest
concentrations. These compounds have very low Koc values. Other compounds
detected, such as tetrachloroethene, have higher Koc values, while still others, such as
1,1-dichloroethene, have lower Koc values. Secondly, the organic carbon content
(0.065%) of the aquifer and soil materials at the Macon/Dockery site is also very low
(see Appendix K). An average ~ value of 0.105 was selected for use in the analytical
model calculations, based on ~ values for several volatile organic compounds detected
at the site (Appendix K).
Model calculations were made for the Macon site and for the Dockery site using ground-
water flow velocities calculated for each site. The linear velocity at the Macon site was
calculated to be 0.21 ft/day. The average linear velocity at the Dockery site was
calculated to be 0.16 ft/day (see Section 4.6.4).

their respective source areas toward ground-water discharge areas,
which are Solomons Creek and the Pee Dee River.
Solomons Creek marshes, Solomons Creek, and the Pee Dee River act
as potential ground-water discharge areas and may serve to assimilate
residual chemicals transported in ground water.
7.3 Future Studies
Based upon the results of the RI, the FS will consider the need for potential remediation
to attain all ARARs. Conditions which may present the need for remediation include:
•
•
•
•
•
Discharge of ground water to Solomons Creek marshes, Solomons
Creek, and the Pee Dee River.
Potential for exposure to on-site waste materials located in Lagoon 1 O
and above ground storage tanks, vats, and tankers.
Potential for exposure to on-site chemical residuals via surface soil
erosion and direct contact.
Potential for exposure to on-site chemical residuals due to seasonal
reversals of in ground-water flow directions.
Presence of metals in ground-water related to suspended sediment in
the samples or site-related sources.
