RE: Groundwater Monitoring Report
TransMontaigne – Greensboro Terminal
6801 W. Market St., Greensboro, Guilford County, North Carolina
NCDENR Incident No. 6367
Dear Mr. Mao:
This letter presents results of groundwater sampling and analysis completed in January 2018 for the TransMontaigne
terminal facility referenced above in Greensboro, North Carolina. The activity represents the second groundwater
sampling/analysis event completed under the May 15, 2017 New Technology Cleanup Plan (NTCP) for the site,
which was approved by the North Carolina Department of Environmental Quality (NCDEQ) via a May 22, 2017
letter to TransMontaigne.
1.0 Groundwater Sampling and Analysis Methods
A facility map showing site monitoring wells is provided in Attachment 1. Site groundwater sampling was
conducted on January 2, 2018. The event included monitoring-well MW-39, which is the only site monitoring-well
that has contained groundwater COC concentrations above the NCDEQ Gross Contamination Levels (GCLs) since
2009. MW-39 was sampled using the standard purge/sample method, described as follows.
• The well was gauged for depth to groundwater and depth to bottom using an electronic interface probe, which
distinguishes between groundwater and liquid-phase hydrocarbons (LPH). LPH was not detected in the well.
• The well was purged of three standing volumes of groundwater using a dedicated, bottom-loading, disposable
polyethylene bailer and nylon rope;
• Following removal of each standing volume of groundwater, field measurements of purge-water pH,
temperature, dissolved oxygen (DO), and specific conductance were collected;
• Within 24 hours following purging, a groundwater sample was collected using a bottom-loading disposable
bailer and nylon rope, transferred to labeled, laboratory-prepared sample bottles, and placed on ice in a cooler.
• The groundwater sample was submitted under chain of custody to ESC Lab Sciences (ESC) and analyzed for
volatile organic compounds (VOCs) by EPA Method 8260.
2.0 Groundwater Sampling and Analysis Results
The laboratory report of analysis for the January 2018 groundwater sample from MW-39 is provided in Attachment
2. Results of analysis are summarized as follows. A historical summary of groundwater analysis results for MW-39
is provided in Attachment 3. Historical groundwater-level data for MW-39 is provided in Attachment 4.

(1) Detected COCs are listed.
(2) North Carolina Groundwater Standard under 15A NCAC 2L .0202.
As shown above, no COCs were detected at concentrations above GCLs in the January 2018 groundwater sample
from monitoring-well MW-39.
3.0 Discussion
Results of January 2018 groundwater sampling/analysis indicate two consecutive quarters of site groundwater
monitoring with no detected COC concentrations at levels above GCLs. In accordance with the May 2017 NTCP,
TransMontaigne will now proceed with the remaining NCDEQ requirements for risk-based site regulatory closure
under 15A NCAC 2L .0507(d). These will include preparation of a Notice of Contaminated Site (NOCS) and
Declaration of Perpetual Land-Use Restrictions (DPLUR) in accordance with NCDEQ guidelines, plus completion
of a public notice process. The NOCS and DPLUR will be submitted to NCDEQ for approval prior to filing with
the Guilford County Register of Deeds.
Based on the previous detections of benzene and MTBE at concentrations above North Carolina groundwater
standards in deep saprolite and bedrock monitoring-wells MW-18 and MW-49, located in the southwest corner of
the TransMontaigne site, near the property boundary with the Plantation Pipeline property, it is acknowledged that
groundwater containing benzene and/or MTBE concentrations may have, or could in the future, migrate into the
Plantation Pipeline property. In response, as part of the NOCS process, written consent from Plantation Pipeline
will be pursued.
Professional certification for this report is provided in Attachment 5. If you have any questions or would like any
additional information, please do not hesitate to call.
Sincerely,
Peter J. Dressel

ONE LAB. NATIONWIDE.GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)
Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and
Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be
detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, or if concentrations of analytes in the sample are higher than the
highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value
different than 1 is used in this field, the result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.
J4 The associated batch QC was outside the established quality control range for accuracy.
