PROJECT SUMMARY

 Based on previous reports completed by Excel and other consultants, the site is classified
as “Intermediate” risk by NCDENR with an Industrial/Commercial setting. Figure 1 in
Appendix B depicts the site location.

 As directed by the NCDENR, one additional downgradient monitoring well (MW-13) and two
vapor extraction wells (SVE-1 and SVE-2) were installed November 24, 2014. Replacement
monitoring well MW-2R was installed January 15, 2015. The site plan depicting the
monitoring well locations is presented as Figure 2, in Appendix B.

 The onsite remediation system was placed into operation in January of 2015. The soil vapor
extraction system is comprised of two vapor extraction wells. A summary of the field
activities associated with the monthly operation and maintenance is given in subsequent
sections of this report. Copies of system maintenance forms are included in Appendix D.

 Operation of the remediation system has resulted in a reduction of LNAPL in MW-2 from a
maximum thickness of 0.44 feet measured in April of 2015 to a current thickness of 0.05 feet
during the reporting period. LNAPL in MW-4 is observed to have decreased from a
maximum thickness of 0.02 feet to a not measurable thickness.

 On November 17, 2015, an Excel representative collected liquid level data for all monitoring
wells as part of the groundwater sampling event. Liquid level data for monitoring wells MW-
1, MW-2R, MW-3, MW-4, MW-6, MW-7, MW-8, MW-9, MW-10, MW-11, and MW-13 is
included in Appendix A, Table 1. During the sampling event, free product was observed in
monitoring wells MW-2R and MW-4. Based on the liquid level data collected, groundwater
flow is estimated to be to the south. A groundwater contour map is included in Appendix B,
Figure 3.

 Groundwater quality samples were collected from monitoring wells MW-1, MW-3, MW-4,
MW-6, MW-7, MW-8, MW-9, MW-10, MW-11, and MW-13 on November 17, 2015. The
groundwater samples were laboratory analyzed for full range volatile organic compounds
(VOCs) by EPA Method 6200B. Monitoring well MW-2R was not sampled due to the
presence of free product; monitoring wells MW-5 and MW-12 could not be located. A map
depicting the estimated extent of free product is provided as Figure 4.

 The results of the laboratory data for the groundwater samples collected were compared
against the NCAC 2L Standards and Gross Contamination Levels (GCLs). The analytical
data presented for the constituents detected was determined based on the highest result
from the various EPA Methods described above. A review of the laboratory analytical results
indicated the following constituents were above applicable regulatory standards:

 Benzene
 GCL: MW-1, MW-3 and MW-7
 NCAC 2L: MW-9 and MW-10
 Toluene
 NCAC 2L: MW-1, MW-3, MW-4, MW-6, and MW-7
 Ethylbenzene
 NCAC 2L: MW-3, MW-6 and MW-7

 Total Xylenes
 NCAC 2L: MW-1, MW-3, MW-4, MW-6, MW-7, and MW-9
 Methyl-tert-butyl-ether (MTBE)
 GCL: MW-1, MW-3, MW-6 and MW-7
 NCAC 2L: MW-8 and MW-10
 Diisopropyl Ether (IPE)
 NCAC 2L: MW-3 and MW-7
 Naphthalene
 NCAC 2L: MW-9 and MW-10
 1,2-dichloroethane
 NCAC 2L: MW-10
 1,2,4-trimethylbenzene
 NCAC 2L: MW-3, MW-6, and MW-7
Current groundwater analytical data is summarized in Table 2 and a summary of historical
groundwater analytical data is included in Table 3 of Appendix A. Figure 5 in Appendix B
depicts select groundwater constituents. Copies of the current laboratory analytical results
are included in Appendix D.

 Results of past receptor surveys completed by Excel during assessment activities indicate
that supply wells were not identified within 1,500 feet of the property.

Additionally, according to the USGS Topographical Map no surface water bodies are located
within 1,500 feet of the source area.

RECOMMENDATIONS

At this time and based on the results of the November 2015 sampling event, Excel recommends
continued operation of the soil vapor extraction remediation system, free product recovery
efforts at monitoring wells MW-2R and MW-4, and continuing semiannual groundwater sampling
of select wells.

PROJECT INFORMATION
PRIMARY CONSULTANT: Excel Civil & Environmental Associates, PLLC
PROJECT MANAGER: Mike Stanforth
SITE CONTACT: Robert Gresham
SITE HISTORY: In May 1999, seven steel regulated USTs were
removed from the site (Figure 1, Appendix A).
Samples collected during closure activities by
Wallace-Lee Consultants, LLC (WLC) revealed
elevated levels of hydrocarbons. An LSA Report was
completed by WLC in April 2000 with an LSA
Addendum completed by WLC in December 2000,
which concluded that groundwater at the site
contained constituents levels exceeding both NCAC
2L standards and GCLs. During LSA activities
conducted by WLC, free phase LNAPL was
discovered at the site in monitoring well MW-2. Free
product recovery efforts reportedly began in February
2000 by monthly site visits for liquid level gauging
and hand bailing.
To date, eight Aggressive Fluid Vapor Recovery
(AFVR) and two 100-hour Mobile Multi-Phase
Extraction (MMPE) events have previously been
conducted at the site by WLC.
GENERAL GEOLOGY: The subject site is located in the Milton Belts of the
Inner Piedmont Geologic Physiographic Province. The
1985 USGS Geologic Map of North Carolina indicates
that rock in this area is commonly characterized by
inequigranular and megacrystic biotite gneiss and
schist.

perform routine O & M. Upon arrival, the system was operational. During the visit
the air-water separator was drained, the system checked, and records made. Free
product recovery skimmers and associated thicknesses were evaluated in MW-2
and MW-4. The system was operational at departure.
10/9/15: Excel conducted a regularly scheduled monitoring and maintenance site visit to
perform routine O & M. Upon arrival, the system was operational. During the visit
the air-water separator was drained, the system checked, and records made. Free
product recovery skimmers and associated thicknesses were evaluated in MW-2
and MW-4. The system was operational at departure.
11/17/15: Excel conducted a regularly scheduled monitoring and maintenance site visit to
perform routine O & M. Upon arrival, the SVE system was operational and the air
compressor was down. Oil was added to the air compressor and the system control

ONE LAB. NATIONWIDE.CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times. All MDL (LOD) and RDL (LOQ)
values reported for environmental samples have been corrected for the dilution factor used in the
analysis. All Method and Batch Quality Control are within established criteria except where addressed
in this case narrative, a non-conformance form or properly qualified within the sample results. By my
digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the
laboratory as having the potential to affect the quality of the data have been identified by the
laboratory, and no information or data have been knowingly withheld that would affect the quality of the
data.
