1.0 INTRODUCTION
August 10, 2004

' Green Star Environmental (Green Star) has completed one authorized groundwater sampling event
at the former Carolina Trailways (hereinafter "the Site") located at 1201 South Blount Street in
Raleigh, Wake County, North Carolina. The sampling was conducted in response to a letterfrom the
NCDENR dated November 7, 2003. The work was conducted in general accordance with directives
outlined in the UST Section, Division of Waste Management (DWM), North Carolina Department of
Environmental and Natural Resources (NCDENR) guidelines (NCDENR Guidelines) entitled "UST
Section Guidelines for Sampling" and dated September 1, 2003.
2.0 SITE DESCRIPTION
The Carolina Trailways facility is located at 1201 South Blount Street, in Raleigh, North Carolina.
The site is bound by Bragg Street to the North, Blount Street to the West, Branch Streetto the South
and Person Street to the East. A Site Location Map and Site Detail Map are presented as Figures 1
and 2, respectively.
3.0 GROUNDWATER MONITORING ACTIVITIES
On May 20-21, 2004, monitoring wells MW-1 through MW-12 and DW-1 and DW-2 were gauged to
determine the depth to groundwater, depth to non -aqueous phase liquids (PSH) if present, and
depth to bottom. An ORS® interface probe was used for the well gauging process. Proper
' decontamination of the interface probe was conducted between each well to prevent possible cross
contamination. Monitoring well MW-6, located in the center of South Blount Street, apparently was
paved over during road repair. A PSH thickness of 0.61 feet was measured in monitoring well MW-9
on May 20, 2004. The PSH plume is limited at this time to monitoring well MW-9. Further information
about the PSH present in well MW-9 is discussed in Section 3.6.
A water well search was submitted in the Monitoring Report, Site Reconnaissance Survey and
Comprehensive Site Assessment Addendum dated July 2, 2001. No water -supply wells were found
within a'/2 mile radius of the site. During the water well supply search, it was found that all occupied
properties within the 1,500-foot search radius were connected to the City of Raleigh water supply as
indicated by water meters. Based on topographic maps and limited site reconnaissance, there are
no surface water bodies within 1,500 feet of the source area of release. The closest body of water is
the Rocky Branch of Walnut Creek located approximately 2,000 feet west of the source area for the
release. Subsurface structures in the vicinity of the site are limited to underground utilities and on -
site service pits. Historically, groundwater occurs between 13 and 18 feet below ground surface at
the site therefore is unlikely to impact any of the subsurface structures.
■ Depth to groundwater at the water table ranged from 12.38 feet (MW-2) to 14.85 feet (MW-1) below
top of casing (btoc) during the May 2004 gauging event. Atdeep telescoping wells DW-1 and DW-2,
' the depth to groundwater measurements were 14.61 feet and 14.66 feet, respectively. Levels were
measured from the top of the PVC casing for each well using an ORS® interface probe. The top of
each well casing was surveyed relative to an arbitrary benchmark to establish relative casing
' elevations and ultimately groundwater gradient. Groundwater level measurements from the May
2004 event and cumulative groundwater level measurements are attached as Table 1 and Table 2,
respectively. The groundwater gradient map, attached as Figure 3, indicates a groundwater flow
towards the southwest. This direction is consistent with previous groundwater monitoring events. A

Maps are attached as Appendix A.
The following sections related to the May 2004 monitoring event include Groundwater Sample
Collection and Laboratory Analysis (Section 3.1), Assessment of the Analytical Results (Section
3.2), Quality Assurance (Section 3.3), and Waste Disposal (Section 3.4). PSH thickness, as
measured before and after three past aggressive fluid and vapor recovery (AFVR) events, is briefly
discussed in Section 3.5.
3.1 Groundwater Sample Collection
Groundwater samples were collected on May 20-21, 2004; handled and analyzed in accordance
with North Carolina UST Section requirements. Prior to sample collection, monitoring wells were
' purged of three well volumes or until dry. Purging was accomplished by hand bailing using a single -
use disposable polyethylene bailer.
Groundwater samples were collected using single -use, polyethylene disposable bailers. All
groundwater samples were collected in laboratory prepared sample containers. The samples
analyzed for volatile organic compounds (VOCs) using EPA method 602 were preserved with
hydrochloric acid (HCI). The samples analyzed for semi-VOCs by EPA Method 625 were collected in
new unpreserved containers provided by the laboratory. All samples were properly labeled, entered
on a Chain of Custody and immediately packed on ice at 4°C.
' Sample analysis for the May 2004 event was selected based on the directive of Ms. Karen Harmon
of the NCDENR in a letterdated November 7, 2003. Wells were sampled during the May2004 event
in accordance with the following matrix:

3.2 Assessment of Analytical Results
Groundwater samples obtained during the May 2004 groundwater -monitoring eventwere shipped to
a North Carolina certified laboratory in Houston, Texas (SPL, Inc.) for analytical testing. Review of
the laboratory results from the November 25, 2003 groundwater -monitoring event (Table 3) indicates
that benzene was detected in two samples at concentrations exceeding the North Carolina
Groundwater Quality Standard (NCGQS) of 1 µg/L (ppb). Concentrations of benzene reported for
the groundwater samples included MW-3 (6.5 ppb) and MW-4 (2.0 ppb). Naphthalene was detected
in two of the samples, MW-1 (26 ppb) and MW-3 (75 ppb) at concentrations exceeings the NCGQS
of 21 ppb. Figures 5 and 6 show the location of the benzene and naphthalene plumes, respectively.
Two benzene plumes are located on the site, adjacent to the western and southern property lines
(Figure 5). The southern plume exhibited higher benzene concentrations (6.5 ppb and the greater
than 6.5 ppb (assumed) of benzene present at well MW-9 (this well was not sampled due to the
presence of 0.6 feet of PSH)). Based on the May 2004 data and the estimated plume extents shown
in Figure 5, the western plume is localized around well MW-4. The southern plume measures

' Greyhound Lines, Inc August 10, 2004
Green Star Project No. 03-1029-3 Page 3
approximately 40 feet by 64 feet. One naphthalene plume is present along the southern property line
(Figure 6). Based on the May 2004 data and the estimated plume extent shown in Figure 6, this
elliptical -shaped plume is approximately 132 feet in length and varies in width from 10 to 38 feet. No
' other constituents were reported with a concentration above the. NCGQS during the May 2004
groundwater -monitoring event.
Semi-VOC analytes chlorobenzene, 1,2,4-tdmethylbenzene, and 1,3,5-tdmethylbenzene were
reported as tentatively identified compounds (TICS) in groundwater samples MW-1 and MW-3. We
are providing these TIC results for informational purposes'. The estimated concentrations for the
three TICS are noted on Table 3 and are below established NCGQS. TICs are reported as
' "estimated" concentrations because laboratory instrumentation is not calibrated specifically for every
potential compound. Therefore, the concentration reported by the lab is estimated based on the
compounds response to the nearest known standard (ENCO, 2001).
Additionally, toluene and ethylbenzene were detected in one monitoring well (MW-3) at
concentrations of 4.8 ppb and 9.7 ppb, respectively. Xylenes were detected in monitoring wells MW-
1 (7.4 ppb) and MW-3 (46 ppb). Concentrations of toluene, ethylbenzene, and xylenes were not
detected in other groundwater samples collected during the May 2004 groundwater event at
concentrations above the Method Detection Limit (MDL).
Based on laboratory analytical results from the May 2004 sampling event, chlorobenzene, 1,2-
dichlorobenzene, 1,4-dichlorobenzene, isopropyl ether (IPE) and methyl tert-butyl ether (MTBE)
were also detected below their NCGQS (Table 3).
A summary of the analytical results for groundwater for the May 2004 event and past events are
presented in Tables 3 through 5. Monitoring well construction information is presented in Table 6. A
copy of the laboratory results, including chain of custody documentation, is attached as Appendix B.
Line graphs showing contaminant concentrations (benzene and naphthalene) and groundwater
elevationversus time for wells MW-3, MW-4, MWA 1 and MW-12 are included in Appendix C.
3.3 Quality Assurance
JOne trip blank sample of clean reagent water in a 40 ml vial for determination of VOC concentrations
was included in the coolers used for groundwater sample storage during the sampling event.
Laboratory results from the trip blank analysis indicated all constituents tested were below detection
limits.
3.4 . Waste Disposal
Purge and decontamination water from the May 2004 monitoring well sampling event is pending
disposal.
i Environmental Conservation Laboratories, Inc. (ENCO) states "Such concentrations should never be relied upon for
regulatory purposes." in reference to TICS in their guidebook (Page 23) "Environmental Analytical Chemistry for
People Who Don't Really Care by Those Who Do, Sixth Edition", March 2001.

3.5 December 2003 to February 2004 AFVR Events
Mid -Atlantic, on behalf of Green Star, completed three Aggressive FluidNapor Recovery (AFVR)
events on December 17, 2003, January 14, 2004 and February 24, 2004. The results of these
events were presented in the free product recovery report submitted to NCDENR in June 2004.
However, PSH thickness measurements made before and after each event and the amount of free
' product recovered is useful to the current monitoring report discussion.
Table 7 shows the PSH thickness measured in well MW-9 prior to each recovery event and
approximately one week after each event. At the end of each AFVR event, there was no measurable
thickness of PSH. The prior -to -event PSH data show that the thickness of PSH decreased from the
first AFVR event in December 2003 to the third AFVR event in February 2004. The total gallons of
liquid PSH recovered also decreased between the first (5 gallons) and second event (nil).
' Recovered PSH during the third event was also similar to the second (nil)).
4.0 SUMMARY AND CONCLUSIONS
Based upon the results of the groundwater -monitoring event, the following summary and
conclusions are provided.
Free Product (PSH) was measured only in well MW-9 during the May 2004 sampling event.
1 • Concentrations of benzene and naphthalene exceed established NCGQS. The maximum
benzene concentration during the May 2004 event was 6.5 ppb in monitoring well MW-3.
Naphthalene was detected in two wells (MW-3 and MW-1) during the November2003 event
with a maximum concentration of 73 ppb (MW-3).
• Benzene concentrations from the May 2004 event exceeded the NCGQS in monitoring wells
MW-3 (6.5 ppb) and MW-4 (2.0 ppb).
' • Naphthalene concentrations from the May 2004 event exceeded NCGQS in monitoring well
MW-1 (26 ppb) and MW-3 (75 ppb).
All other constituents thatwere analyzed by EPA Methods 602 and 625 were below NCGQS.

PO Number:
State: North Carolina
State Cart. No.: 443
Date Reported: 6/4104
Please note that in an effort to meet North Carolina's Detection Limits, the following compounds are reported at the method detection limit
' (MDL) or below SPL's reporting limit:
Waters:
' Benzo(a)anthracene, Benzo(b)fiuoranlhene, Benzo(k)fiuoranthene, Benzo(a)pyrene, Sis(2-chloroethyl)ether, Dibenz(a,h)anthracene,
Hexachlorobutadiene, and Ideno(1,2,3-cd)pyrene. Nolh Carolina's Detection Limits for all of these analyles are below SPL's MDL's.
' Matrix spike (MS) and matrix spike duplicate (MSD) samples are chosen and tested at random from an analytical batch of Nke" matrix to
check for possible matrix effect. The MS and MSD will provide she specific matrix data only for those samples which are spiked by the
laboratory. Since the MS and MSD are chosen at random from an analytical batch, the sample chosen for spike purposes may or may not
have been a sample submitted in this sample delivery group. The validity of the analytical procedures for which data is reported in this
' analytical report is determined by the Laboratory Control Sample (LCS) and the Method Blank (MB). The Laboratory Control Sample (LCS)
and the Method Blank (MB) are processed with the samples and the MS/MSD to ensure method criteria are achieved throughout the entire
analytical process.
' Your sample ID "MW-12" (SPL ID: 04050896-12) was randomly selected for use in SPL's quality control program for the Purgeable
Aromatics analysis by EPA Method 602. The MS and/or MSD recoveries were outside of the advisable quality control limits for
Isopropylether (Batch ID: R112422) due to matrix interference. A Laboratory Control Sample (LCS) was analyzed as a quality control
check for the analytical batch and all recoveries were within acceptable limits.
Any other exceptions associated with this report will be footnoted in the analytical result page(s) or the quality control summary page(s).
Please do not hesitate to contact us If you have any questions or comments pertaining to this data report. Please reference the above
' Certificate of Analysis Number,
This report shall not be reproduced except in full, without the written approval of the laboratory. The reported results are only
representative of the samples submitted for testing.
' SPL, Inc. Is pleased to be of service to you. We anticipate working with you in fulfilling all your current and future analytical needs.
