Each of the soil samples was assigned a unique name which included the sample location and
depth. Thirty-seven (37) soil samples were submitted for laboratory analysis. Duplicate and
matrix spike/matrix spike duplicate (MS/MSD) samples were retained to ensure Level II
laboratory quality Assurance/Quality Control (QA/QC). Quality control samples and
corresponding samples are listed below.
• DUP 011309-A — SB-I (1')
• DUP 011309-B — SB-2 (0-0.5')
• DUP 011309-C — SB-35 (10-11')
• DUP 011309-D — SB-12 (0-1')
• DUP 011409-A — SB-I I (1')
• MS/MSD — SB-20 (0-1')
• MS/MSD-2 — SB-29 (14-15')
A summary of the soil sample and analytical program is presented in Table 1. Results are
presented in Table 2 and discussed in Section 3.3.
Laboratory analyses were conducted by Prism Laboratories, Inc., a North Carolina -certified and
Woman -owned Business Enterprise (WBE) analytical laboratory located in Charlotte, NC.
Samples were placed into the appropriate containers, stored on ice in coolers, and submitted to
the laboratory under standard chain -of -custody protocol.
After soil sampling was completed, each of the DPT bore holes, except those borings converted
to temporary or permanent monitoring wells were backfilled with soil and bentonite to surface
grade and capped with concrete. Boring and monitoring well logs are provided in Appendix A.
Investigation -derived waste was contained in 55-gallon UN1A steel drums temporarily stored
onsite. A label indicating that the drum(s) are "on hold pending analysis" was affixed to the
exterior of the drum(s) and the contents of the drum(s) "investigative derived waste — soils" was
annotated along with the generation date(s) on the label. Analyses of the drummed material
indicated the material was non -hazardous. The drums were transported and properly disposed at

an offsite permitted facility by Garco, Inc. on May 13, 2009. A copy of the waste profiles and
Certificate of Disposal are provided in Appendix B.
2.4.1 Study Area 1
Soil borings installed within Study Area 1 included those designated as S13-1, S13-2, S13-3, S13-6,
S13-7, SB-10, SB-11, S13-12, S13-13, SB-14, SB-15 and S13-17. Locations of these borings and
wells are shown on Figure 3. All soil samples obtained for laboratory analysis in Study Area 1
were within 3 feet of surface grade due to the shallow ground water table encountered in this
area. Soil samples from the three Study Areas were analyzed according to the plan presented in
Table 1.
S13-4 and S13-5 were advanced but soils were not sampled because ground water was
encountered within 1/2 foot of surface grade. Soil was also not collected from S13-8 and S13-9
because of the shallow (less than 3' bgs) ground water level. These borings were proposed to
evaluate unsaturated soil conditions at the bottom of the former 3,000 thinner overflow tank and
the former 7,500 gallon naptha tank. However, due to the high water table, samples collected at
the required depth would have been below the water table. In a January 13, 2008 conversation
with Mr. Michael Rogers of the NC DENR UST Section, Winston Salem Regional Office, H&H
was advised that collection of soil samples at these locations would not be necessary because the
base of the former USTs were within saturated soils.
Permanent monitoring wells MW-lA, 2A, 3A and 4A were installed within Study Area 1 and
soil samples were obtained from each of these wells during their installation
2.4.2 Study Area 2
A single boring (SB-27) was installed in Study Area 2 to evaluate soil and ground water
conditions at the location of the release from a former 550 gal gasoline UST (Figure 4). SB-27
was installed to a depth of 22 ft-bgs in the center of the former tank pit. A soil sample was
retained from SB-27 at a depth of 8 to 9 ft-bgs, the anticipated bottom of the former tank pit, in

native soils. Boring SB-27 was advanced approximately 2 feet below the water table, to install a
temporary monitoring well and obtain a ground water sample. Installation and sampling of the
temporary well at this location is discussed in Section 2.5.2.
2.4.3 Study Area 3
Thirteen (13) soil borings (SB-28 to SB-40) were installed within Study Area 3 as shown on
Figure 4. In accordance with the QAPP, soil samples within this area were generally obtained
within 3 ft. of surface grade (with the exception of borings SB-28, SB-29 and SB-35).
Samples SB-28 and 29 were obtained from depths of 14 to 15 ft. bgs, approximately 2 ft. below
the estimated base depth of an abandoned fuel oil UST. Boring SB-29 was placed immediately
downgradient of the former UST and extended to a depth of 20 ft. bgs to install a temporary
monitoring well. Installation and sampling of the temporary well at this location is discussed in
Section 2.5.3.
Sample SB-35 was retained from 10 to 11 ft. bgs, approximately 2 ft. below the estimated base
depth of two gasoline USTs which were removed in 1989. Boring SB-35 was extended to a
depth of 20 ft-bgs to install a temporary monitoring well. Installation and sampling of the
temporary well at this location is discussed in Section 2.5.3.
Samples SB-36 and SB-37 were collected to assess potential impacts from two in -floor
vaults/sumps in the former wood processing area. The former use of these features is unknown.
These vaults/sumps were approximately eight feet long by four feet wide by two feet deep. The
features were dry with no signs of staining or sludge. Samples were collected adjacent to and
immediately beneath the bottom of the vaults/sumps.

2.5 Monitoring Well Installation
As specified in the QAPP, four (4) permanent ground water monitoring wells (MW-IA, MW-
2A, MW-3A and MW-4A) were installed to assess the shallow ground water within Study Area
1. In addition, soil borings SB-2, SB-4, SB-6, SB-7, SB-10, SB-14, SB-27, SB-29 and SB-35
were extended into the water table and completed as temporary monitoring wells. Both
permanent and temporary wells were constructed in accordance with the QAPP, and North
Carolina Administrative Code (NCAC), Chapter 15A, Subchapter 02C, Section .0108 (Standards
of Construction: Wells Other Than Water Supply). After sampling, the temporary wells were
abandoned in accordance with the above standard. Well Construction records for the installation
of these wells are presented in Appendix C. Permanent monitoring well construction data are
summarized in Table 3. Installation of permanent and temporary wells and sampling of ground
water are discussed below.
2.5.1 Study Area 1
Within Study Area 1, four (4) permanent ground water monitoring wells (MW-IA, MW-2A,
MW-3 A and MW-4A) were installed at the locations shown on Figure 3. Wells MW-IA, MW-
3A and MW-4A were each installed to 12 ft. bgs, while MW-2A was installed to 17 ft. bgs.
Wells were installed after the collection of soil samples.
Temporary wells were set in borings SB-2, SB-4, SB-6, SB-7, SB-10 and SB-14 (Figure 3).
After collection of soil samples from these borings, each was extended (if necessary) to penetrate
the water table at their location. Temporary wells were installed and constructed as outlined in
the QAPP. Ground water sampling is discussed in Section 2.6.

2.5.2 Study Area 2
Following collection of soil samples from boring SB-27 (Figure 4), the boring was extended to
22 ft. bgs and a temporary well was installed and constructed as outlined in the QAPP. Ground
water sampling is discussed in Section 2.6.
2.5.3 Study Area 3
After collection of soil samples from borings SB-29 and SB-35 (Figure 4), the borings were
extended to depths of 20 ft. and temporary wells were installed and constructed as outlined in the
QAPP. Ground water sampling is discussed in Section 2.6.
2.6 Ground Water Sampling
Ground water samples were collected from temporary wells installed in borings S13-2, SB-4, SB-
6, SB-7, SB-10, SB-14, SB-27, SB-29 and SB-35 on January 14, 2009. Samples were collected
from permanent monitoring wells MW-IA, MW-2A, MW-3A and MW-4A, installed in Study
Area 1 on January 23, 2009. Prior to sampling, the water level within the well was measured
from ground surface (in the case of the temporary wells) or the top of the well casing (in the case
of the permanent wells). Each well was purged and sampled in accordance with procedures
outlined in the QAPP.
Samples obtained from temporary wells SB-2, SB-4, SB-6, SB-7, SB-10 and SB-14 were
submitted for analysis of VOCs, SVOCs and metals by EPA Methods 8260B, 8270C and
6010B/7471A, respectively. Samples obtained from temporary wells SB-27 and SB-35 were
submitted for analysis of VOCs by EPA Method 8260B and VPH by the MADEP-VPH method.
The sample obtained from SB-29 was submitted for analysis of SVOCs and EPH by EPA
Method 8270C and the MADEP-EPH method, respectively.
Samples from permanent wells MW-IA, MW-2A, MW-3A and MW-4A were submitted for
analysis of VOCs, SVOCs and RCRA metals by EPA Methods 820613, 8270C and

601013/7471A, respectively. In addition to these methods, the sample from MW-4A was also
analyzed for pesticides using EPA Method 8081A.
In accordance with the QAPP, duplicate, matrix spike and matrix spike duplicate samples were
obtained from the temporary and/or permanent wells. Quality control samples and
corresponding samples are listed below.
• GW-DUP-012309 — MW4A
• MS/MSD (1/14/09) — SB-35
• MS/MSD (1/23/09) — MW-3A
Several monitoring wells installed during assessment of the former 550 gallon petroleum UST in
Study Area 2 and were proposed in the QAPP to be sampled. However, field inspection revealed
these wells had been permanently abandoned as part of the NFA granted for this UST.
Therefore, these wells were not sampled as a part of the SA.
Analytical data for the ground water samples are discussed in Section 3.4, and summarized in
Table 4.
2.7 Permanent Well Elevations Measurement
Relative elevations of each permanent well were established on January 23, 2009 utilizing a
transit and stadia rod. A benchmark with an assumed elevation of 500.00 ft. was established at a
random location on the site, and the relative elevation of each well was measured based on the
assumed elevation of the benchmark. The relative elevation data were used to calculate ground
water hydraulic gradient, based on water level elevations also obtained on January 23, 2009.
Relative elevations are presented in Table 3.

Laboratory Analytical Data and Data Validation Summary
Data Validation Summary
In accordance with the December, 2008 Site QAPP, the field and laboratory analytical data were
subjected to review, verification, and validation to ensure that the quality and validity of the data
were acceptable for the stated data quality objectives. A discussion of the field data, laboratory
data, and variations from the procedures outlined in the approved QAPP for the subject site is
presented below.
Field Procedures
The field procedures for sampling, decontamination, calibration, chain -of -custody forms, etc.
were followed in accordance with the QAPP procedures, with seven (7) exceptions:
• The QAPP called for the sampling of five (5) existing monitoring wells within Study
Area 2, associated with the former location of a 550 gallon gasoline UST from which a
release was confirmed and later evaluated, independent of this Phase II SAR. It was
discovered that these five wells had been abandoned prior to the initiation of Phase II
Assessment activities; therefore, the wells were not sampled.
• The QAPP called for the collection of samples from soil borings SB-8 and SB-9,
associated with the former locations of a 3,000 gallon thinner UST (SB-8) and a 7,000
gallon naphtha UST (SB-9). As groundwater was found to be less than 3 feet (ft) beneath
land surface (bls), the collection of these samples from their target samples depths (13-14
ft bls for SB-8 and 7-8 ft bls in SB-9) would have yielded samples in the saturated zone,
and the data for the samples would have been of no value. For this reason, neither of
these borings were completed.
• The presence of groundwater at a shallow depth at the original intended location of
boring SB-3 prompted the relocation of this boring adjacent to a drainage structure
between borings SB-1 and SB-2.
D-1
• The QAPP called for the sampling of soils at the locations of soil borings SB-4 and 5.
Groundwater was encountered within 1 foot of surface grade in each of these borings,
therefore soil samples were not obtained.
• The QAPP called for the collection of samples from hand auger borings SB-18, 19, 25
and 26. Upon attempting to complete these borings, it was found that the crawl space of
the former finishing plant was underlain by a concrete slab, therefore these samples were
not obtained.
• The QAPP also called for the collection of two (2) samples from hand auger borings SB-
20, 21, 22 and 24. Groundwater was found in each of these borings within 2 ft. of
surface grade, therefore, only a single (shallow) soil sample was retained from these
borings.
• The locations of borings SB-36 and 37 (originally slated for completion near the
southeastern portion of the wood processing area in Study Area 3) were altered to
evaluate the locations of two vaults located within the building. These vaults were not
identified during the Phase I ESA, as they had been covered with equipment and/or
debris which have since been removed.
A field audit was not performed due to the brevity and limited scope of sampling activities.
Field audits were optional per the QAPP.
D-2
Laboratory
A review of the analytical laboratory data is provided below.
• Samples shipped to Prism Laboratories associated with this project were received at the
laboratory in good condition, within the proper temperature range, were properly
preserved, and proper sample volumes were available for analysis.
• Chain -of -custody protocol was properly maintained.
• The requested laboratory analyses were performed by the laboratory on each sample.
Ground Water Samples
• The laboratory supplied trip blank samples to accompany all groundwater samples
submitted for the performance of this project. Each trip blank sample was analyzed by
EPA Method 8260B. Data for trip blank samples associated with this project did not
indicate the presence of targeted compounds at levels above the method reporting limit.
• No target compounds were reported above reporting limits in the method blanks for the
ground water samples.
• Laboratory control samples and matrix spike samples for the water analyses were within
laboratory control limits.
• For laboratory batch ID # Q38858, EPA Method 8270C groundwater analysis, the
recovery for the matrix spike (MS) and matrix spike duplicate (MSD) samples associated
with the compound pentachlorophenol were outside the control limits. The laboratory
control sample (LCS) had acceptable recovery. The compound was not detected in any
D-3
samples submitted within the sample batch at levels exceeding the method reporting
limit.
• For laboratory batch ID # Q38661, EPA Method 8270C groundwater analysis, the
recovery for the matrix spike (MS) and matrix spike duplicate (MSD) samples associated
with the compound pentachlorophenol were above the control limits. The laboratory
control sample (LCS) had acceptable recovery. The compound was not detected in any
samples submitted within the sample batch at levels exceeding the method reporting
limit.
• For laboratory batch ID # Q38641, EPA Method 7471A groundwater analysis, the
recovery for the matrix spike (MS) and matrix spike duplicate (MSD) samples associated
with the element mercury were outside the control limits. The laboratory control sample
(LCS) had acceptable recovery. The compound was not detected in any samples within
the sample batch at levels exceeding the method reporting limit.
Soil Samples
• No target compounds were reported above reporting limits in the method blanks for the
soil sample analyses associated with this project.
• Several compounds were reported with an "H" qualifier in the EPA 8270C analysis
associated with sample SB-15. The "H" qualified indicates that the compounds were
reported at estimated concentrations with a high bias. Analytes in this sample yielded
results that were consistently higher than what was observed in internal standards (which
produced area response below acceptable QC limits). Compounds detected in this
sample may have otherwise been non -detect, because they were detected slightly above
relative detection limits. Compounds benzo(a)anthracene, benzo(a)pyrene,
benzo(b)fluoranthene, and indeno(1,2,3-cd)pyrene were detected slightly above detection
limits, and were subsequently above relative SRGs. SRGs are less than detection limits
for these compounds.
• For laboratory batch ID # Q38605, EPA Methods 8260B and 8270C soils analysis, MS
and MSDs were not available for reporting. LCS has acceptable recoveries for each
method.
• For laboratory batch ID # Q38578, MS for barium: The sample concentration was too
high for recovery evaluation.
• For laboratory batch ID # Q38578, MS for chromium: The MS and MSD recovery were
outside the control limits. Matrix interference is suspected. Post digestion spike
recovery (72%) is outside the acceptable limits (80-120%).
• For laboratory batch ID # Q38578, MS for chromium: The MS and MSD recovery were
outside the control limits. Matrix interference is suspected.
• For laboratory batch ID # Q38578, MSD for chromium: MSD recovery was outside the
control limits.
• For laboratory batch ID # Q38578, MSD for lead: MSD recovery was outside the control
limits.
• For laboratory batch ID # Q38598, LCS for mercury: No MS/MSD with batch - LCS had
acceptable recovery.
• For laboratory batch ID # Q38673, MSD for mercury: MSD recovery was outside control
limits. Serial dilution (5x) difference (25%) was greater than the control limit (10%).
Post digestion spike recovery of 115% was well within acceptable control limits. Matrix
interference suspected.
D-5
• For laboratory batch ID # Q38630, Method Blank (MB) for chromium and lead: MB was
greater than 1/2 the reporting limit, but samples are greater than 1 Ox the MB.
• For laboratory batch ID # Q38630, MS for arsenic, barium, cadmium, lead, selenium and
silver: MS recovery was outside the control limits. Matrix interference is suspected.
• For laboratory batch ID # Q38630, MSD for arsenic, cadmium, chromium, lead, selenium
and silver: MSD recovery was outside the control limits.
Review of laboratory data revealed a disparity between laboratory reporting limits and NCDENR
Health -Based SRGs in soil samples analyzed for SVOCs. The disparity arose directly from
reporting limits being greater than SRGs. This is noteworthy because SVOCs may have been
present in soil samples at concentrations above SRGs yet below reporting limits (non -detect).
The compounds that fall within this range are benzo(a)anthracene, benzo(a)pyrene,
benzo(b)fluoranthene, dibenzo(a,h)anthracene, and indeno(1,2,3-cd)pyrene. After review of the
data and laboratory consultation, it was found that for SVOCs analyzed by EPA Method 8270,
standard detection limits result from the sensitivity of laboratory equipment and are intrinsically
greater than the SRGs in question. Reporting limits for SVOCs found in the following appendix
are the lowest limits the analytical method and laboratory equipment could produce.
Upon analytical data review, verification, and discussions with laboratory personnel, Hart &
Hickman determines that these data are valid and useful for the purposes described in the QAPP.
