Dear Mr. Ziegler:
On August 3, 2012, the Aquifer Protection Section received the Final Project Evaluation for injection
activities conducted under the permit referenced above. This report completes the monitoring and
compliance reporting requirements of the permit. Staff from the Mooresville Regional Office confirmed
that there are no outstanding reporting, compliance, or enforcement issues associated with this permit.
Any other compliance monitoring or reporting requirements of any other regulatory programs shall
continue as needed.
If you wish to conduct future injection operations you must first apply for and receive a new injection
well permit. Operating an injection well without a valid permit could result in a civil penalty of up to
$25,000 per day. Please contact me at 919-807-6412 or [e-mail] if you have any
questions.

The Aquifer Protection Section is currently reviewing the above referenced Permit Application received
June 22, 2010 and has identified an item that needs additional information. Address the following issue
as required:
• A discrepancy exists between the injectant volume indicated in Section IV.B which, appears
to total 40,000 gallons (2000 gallons per event for 20 events), and that indicated in
Attachment D paragraph 2 which would be approximately 8,000 gallons (4,000 gallons per
test area in two test areas). Please provide a more concise explanation of the injection as
based on a per boring estimate for the twenty borings proposed.
• In the above requested per boring explanation, also provide the estimated injection depth
intervals for each zone. In addition, if a boring needs to be advanced by auger, please
provide a description of the method injection will occur.
• Does Figure 1 a. of Attachment H indicate the true dimensions (32' x 21') of the proposed
injection areas?
If you have any questions regarding this request, please contact me at (919) 715. 6168 or email me at
[e-mail]. Thank you in advance for your cooperation and timely response.

Type 5I Wells — In Situ Groundwater Remediation / Type 5T Wells — Tracer Injection
Below is a brief description of the injection procedure and equipment. Additional information can be found in
Attachment D.
1. It is anticipated that a direct push technology (DPT) will be used as a delivery platform. The probe injection pint
will be advanced to the specified depth then the injection point will be uncovered. An injection manifold
inclusive of quick connect couplings, a ball valve, and a pressure gauge will be attached to the top of the DPT
rods. Concurrent with the DPT advancement an Epsom salt solution will be mixed with municipal water to a
sulfate concentration of 2,000 mg/L. Concentrations will be based on calculations and the first batch will be
checked by laboratory analysis;
2. This is a temporary mobile system that is vendor supplied. General components consist of a mixing tank, product
pump, metering and measuring system and affiliated conveyance hose.
3. It is anticipated that the injections will take place in late August 2010. The injection points will be installed using
a Direct Push Technology drilling rig. It is anticipated that several points will be installed at the same time and
then injected solution delivered to several point at the same time. It is anticipated that no more than a 4-5 foot
section will be injected at a time then the DPT will be advanced to the next 4-5 foot interval until the entire 20-
foot depth is complete.

ATTACHMENT A - SITE HISTORY
1) Site Usage
The Site is located in the Paw Creek area of Charlotte, North Carolina, an area
predominantly occupied by petroleum terminal and light industrial facilities. The facility
occupies approximately 26 acres and is bordered by Old Mount Holly Road to the north,
a Kinder -Morgan terminal to the east, vacant property (former National Oil terminal) to
the west, and undeveloped woods to the south. Railroad tracks operated by Piedmont and
Northern Railroad are located directly south of the facility property, beyond which is
situated a Duke Power transmission line right-of-way.
The Site is a petroleum distribution terminal that has been in operation since the 1940s
and was formerly owned jointly by BP and TransMontaigne. Since February 2006 the
facility has been solely owned and operated by BP. The facility contains 19 bulk fuel
storage tanks that are contained within earthen bermed areas and/or excavated areas with
earthen cut -banks.
In addition to the bulk fuel storage tanks, the facility contains a terminal office building,
miscellaneous storage and warehouse buildings, nine process aboveground storage tanks
(ASTs), three underground storage tanks (USTs), a covered tanker truck loading rack,
associated process piping, and an inactive dual -phase vacuum extraction (DPVE)
soil/groundwater remediation system which was removed. The tanker truck loading rack
is located near the northern border of the facility, with access from Old Mount Holly
Road.
Six of the process ASTs, ranging in size from 180 gallons to 8,000 gallons, contain fuel
additives. Two 10,000-gallon ASTs contain petroleum contact water. One 2,000-gallon
AST contains mixed (slop) products. The USTs consist of one 1,000-gallon wastewater
UST (located at the sump near tank 110), one 2,000-gallon used oil UST (located
adjacent to two 10,000-gallon underground oil/water separators), and one 2,000-gallon
vapor recovery unit (VRU) moisture separator UST. A total of seven USTs have been
decommissioned at the terminal.
The Site underwent a modification between September and December 2008 to include
ethanol fuel storage, and an expanded truck loading rack and driveway widening to
accommodate the expansion. Fuel lines were added beginning late 2009.
The terminal is supplied with petroleum products from underground pipelines owned by
Colonial Pipeline Co. and Plantation Pipe Line Co. Two 14-inch diameter feed lines from
Colonial Pipeline enter the facility below ground from the northwest corner. One 10-inch
and one 12-inch feed line from Plantation Pipe Line enter the facility from the southwest
corner. Two abandoned 14-inch underground pipelines enter the facility west side near

the warehouse from the former National Oil terminal. These pipelines formerly supplied
product to the former National Oil terminal via the BP terminal product manifold.
2) Origin of the contamination
Eighteen releases of known and unknown quantities of material have been released at the
site since circa 1950. Refer to Appendix 1 for release information and locations.
3) Previous Remedial Action(s)
The following is a summary of Site environmental remediation activities conducted in
response to various historical facility product releases. Remedial activities are shown in
Figure 4.
Soil Remediation
• September 1991: unknown volume of soil excavated from the area north of
tank 111.
• September 1996: approximately 133 tons of soil excavated from former UST
locations.
• October 1996: approximately 7 tons of soil excavated from the area west of
tank 111.
• March 1997: approximately 24 tons of soil excavated from the area near
tanks 117 and 118.
• April 1998: unknown volume of soil excavated from the area north of tank
112 during installation of interceptor trench.
• May 1998: approximately 312 tons of soil excavated from around tanks 111,
116, 117, 118, and 119.
• January 1999: approximately 420 tons of soil excavated from area
surrounding tanks 117 and 118.
• April 2004: approximately 13 tons of soil excavated from ditches near tanks
117 and 118.
• January 2005: approximately 120 tons of soil excavated from ditches near
tanks 117 and 118.
Groundwater Remediation
• Pump and treat: approximately 4,882,088 gallons of groundwater processed
between 1985 and 1994.
• DPVE: approximately 472,135 gallons of groundwater processed between
1994 and July 2000.

• Interceptor trench: approximately 217,867 gallons of groundwater processed
between 1998 and 2005.
• A Groundwater Permeable Reactive Barrier (PRB) was installed in February
2005. The PRB is filled with granular gypsum and organic topsoil and is
designed to mitigate groundwater contaminant of concern (COC)
concentrations, and prevent further downgradient migration of the
groundwater COC plume through enhanced anaerobic biodegradation.
• An In -Situ Submerged Oxygen Curtain (ISOCTM) was installed from October
31 to November 3, 2005 in the northwestern area of the terminal and is
currently operating.
LNAPL Recovery
• Pump and treat: approximately 6,000 gallons of LNAPL recovered between
1993 and 1994.
• DPVE: approximately 500 gallons of LNAPL recovered between 1994 and
July 2000.
• On -going LNAPL recovery using absorbent socks if present. Measureable
LNAPL last recorded 2005.

ATTACHMENT B - HYDROGEOLOGIC DESCRIPTION
1) Regional Geologic Setting
The facility is situated on the crest and slope of a hill centered on Old Mount Holly Road.
Ground -surface elevations at the facility range from approximately 795 feet relative to
mean sea level (msl) at the northern border of the facility adjacent to Old Mount Holly
Road to approximately 740 feet msl at the southern border of the facility. South of Old
Mount Holly Road, surface drainage is south toward Paw Creek. North of Old Mount
Holly Road, surface drainage is north toward Long Creek.
The Site is located in the Piedmont physiographic province, which is characterized by
moderately level interstream areas separated by broad valleys. Bedrock in Charlotte,
North Carolina is mapped within the Charlotte Belt lithologic division of the Piedmont,
which includes mafic gneisses, amphibolites, metagabbros, and metavolcanic rocks.
According to the Geologic Map of North Carolina (North Carolina Geological Survey,
1985), bedrock beneath the facility consists of metamorphosed quartz diorite or quartzite.
Competent bedrock in the Piedmont province is typically overlain by variable thicknesses
of saprolite and soil, collectively referred to as "overburden." Saprolite consists of rock
that has been subject to chemical weathering, removing up to 60% of the rock mass by
solution, but not affecting volume (Cleaves, 1974). Saprolite commonly retains relict
structures from the parent bedrock. Thicknesses of the overburden in the Piedmont
typically range from 10 to 75 feet, depending on rock composition and topographic
setting (LeGrand, 1988).
2) Significant Changes in Lithology
Based on Site boring logs, subsurface materials at the Site consist of soil and saprolite
overburden, including silty/clayey sand, sandy clay/silt, and silt/clay, overlying
weathered and competent bedrock. Bedrock, meeting the description of metamorphosed
quartz diorite referenced above, has been encountered in Site borings at depths ranging
from approximately 10 to 40 feet below grade and elevations ranging from approximately
729 to 774 feet msl.
Groundwater in the Piedmont province occurs in the overburden under unconfined (i.e.,
water table) conditions, and in the underlying bedrock under both unconfined and
confined conditions. Groundwater in the overburden occurs within pore spaces of the
unconsolidated medium, including relict bedrock structures (i.e., fractures, foliations,
etc.). Due to the typical fine-grained nature and low permeability of saprolite, the
formation is not usually utilized for groundwater production. Groundwater in the
underlying bedrock occurs along zones of secondary porosity, such as fractures,

foliations, solution voids, etc. Most water -supply wells in the Piedmont are completed in
bedrock with surface casings extending through the overburden.
3) Hydraulic Conductivity, etc.
The following is from Piedmont Geologic (August 19, 2005) for the submittal of ISOC
usage under UIC permit WI0300106:

Based upon (1) the most recent hydraulic conductivity test results (i.e., from MW14R)
with a hydraulic conductivity of 0.06 feet per day (ft/d), (2) the maximum historical
observed groundwater gradient across the Terminal of 0.11 foot vertical per foot
horizontal (ft/ft), and (3) an estimated effective porosity of 10 percent, the calculated
porosity -corrected groundwater flow velocity is 0.066 ft/d or approximately 24 feet per
year (G&E, March 13, 1998).
Transmissivity (T) and specific yield have not been determined for this site as pumping
tests have not been conducted.

(4) Depth to Mean Seasonal High Water Table
Based on recent and historical depth to groundwater measurements, the depth to groundwater
across the site varies seasonally from around 3 feet bgs to over 13 feet bgs, with the shallower
depths occurring during the dry summer months. Depth to groundwater measurements in Sulfate
Injection Area 1 (near monitoring well MW-26) varied from 6 feet in June 2009 to about 6.3 feet
in December 2009. Depth to groundwater in Sulfate Injection — Area 2 (near monitoring well
(UW-08) varied from 4.6 feet in June 2009 to 4.77 feet in December 2009. The estimated depth
to the mean seasonal high water table is on the order of 7.5 feet bgs at this site.

ATTACHMENT C - INJECTION FLUID COMPOSITION
The proposed injectant is a magnesium sulfate solution. Magnesium sulfate solution
(2,000 mg/L) is completely miscible in water. Magnesium sulfate completely
disassociates in water and creates a sulfate salt solution. The solution is non -toxic (see
MSDS) and is stable in the environment. The use of magnesium sulfate has been
previously approved for injection by the NCDENR UIC program. Additional details
regarding the injection mixture are provided in Attachment D (2).
A sodium bromide solution (up to 1,000 mg/L) will be added to the magnesium sulfate
solution as a tracer. The MSDS is attached. The use of bromide has been previously
approved for injection by the NCDENR UIC program.

ATTACHMENT D — Injection Rational
(1) Remedial Goals
The goal of this project is to evaluate the efficacy of anaerobic bioremediation of
petroleum based contaminants at the site. Much research has indicated that plumes that
are depressed of oxygen are intrinsically capable of reducing BTEX contamination but
are limited by the concentration of sulfate or other reducing compounds.
(2) Contaminant / Injectant Reactions
The concentration and volume of injectant have been calculated and estimated based on
estimated pore volume within the soil matrix and previous site experience. The available
pore volume is calculated at 12,000 gallons per area. Based on injection experience it is
estimated that approximately 4,000 gallons of solution could be injected into each area.
Based on this volume and the available pore space an injection concentration of 2,000
mg/1 is proposed. It is assumed that within days of injection the concentration will be
diluted by 50% by mixing with the surrounding groundwater that would yield an
effective concentration of 1,000 mg/L for anaerobic reduction. Based on a range of 1st
order biological reduction rates (k) between 0.043/day and 0.130/day it is estimated that
the ending concentration of sulfate at the end of the approximate 3-month pilot test will
be below 250 ppm (secondary MCL).
URS evaluated the potential fate of sulfate injected into the groundwater at the site.
Calculations were made using dispersion as the only mechanism for reducing
concentrations (i.e., assumed no retardation, precipitation, or uptake during contaminant
degradation). A single injection of 4,000 gallons of water containing 2,000 mg/L
dissolved sulfate was assumed. The calculation also assumed a minimum travel path to
the property boundary and calculated travel time of 173 days along that path based on site
conditions. Using very conservative estimates of dispersion, the maximum sulfate
concentration projected at the property boundary was calculated to be less than 100 mg/L,
which is well below the MCL of 250 mg/L. Details of the calculations are available upon
request.
Bromide solutions are well known in industry as a tracer due to the relative ease of
detecting it in groundwater. The bromide will be added as a tracer in the Sulfate solution
as an aid to further evaluate the flow regime and as a control for estimated biological
uptake of sulfates.
(3) Summary Results of Previous Modeling or Testing
URS evaluated the potential fate of sulfate injected into the groundwater at the site.
Calculations were made using dispersion as the only mechanism for reducing
concentrations (i.e., assumed no retardation, precipitation, or uptake during contaminant
degradation). A single injection of 4,000 gallons of water containing 2,000 mg/L
dissolved sulfate was assumed. The calculation also assumed a minimum travel path to

the property boundary and calculated travel time of 173 days along that path based on site
conditions. Using very conservative estimates of dispersion, the maximum sulfate
concentration at the property was calculated to be less than 100 mg/L, which is well
below the MCL of 250 mg/L. Details of the calculations are available upon request.
See the attached paper for additional information and case studies. The reactions utilize
sulfate to reduce BTEX concentrations to CO2 and varying concentrations of sulfate
reduction daughter products. Hydrogen sulfide can be produced but it is anticipated that
most of the sulfate will be converted into sulfite.

Abstract
Anaerobic microbial activities such as sulfate reduction are important for the degradation of
petroleum hydrocarbons (PHC) in contaminated aquifers. The objective of this study was to
evaluate the feasibility of single -well push-pull tests in combination with stable sulfur isotope
analyses for the in situ quantification of microbial sulfate reduction. A series of push-pull tests
was performed in an existing monitoring well of a PHC-contaminated aquifer in Studen (Switzer-
land). Sulfate transport behavior was evaluated in a first test. In three subsequent tests, we injected
anoxic test solutions (up to 1000 1), which contained 0.5 mM bromide (Br-) as conservative tracer
and 1 mM sulfate (SO,a-) as reactant. After an initial incubation period of 42.5 to 67.9 h, up to
1100 1 of test solution/groundwater mixture was extracted in each test from the same location.
During the extraction phases, we measured concentrations of relevant species including Br-,
SO4_ and sulfide (S(-II)), as well as stable sulfur isotope ratios (834S) of extracted, unconsumed
SO. and extracted S(-II). Results indicated sulfate reduction activity in the vicinity of the test
well. Computed first -order rate coefficients for sulfate reduction ranged from 0.043 ± 0.013 to
0.130 ± 0.015 day-1. Isotope enrichment factors (e) computed from sulfur isotope fractionation
of extracted, unconsumed SO - ranged from 20.2 ± 5.5%o to 22.8 ± 3.4%0. Together with
observed fractionation in extracted S(-II), isotope enrichment factors provided strong evidence for
microbially mediated sulfate reduction. Thus, push-pull tests combined with stable sulfur isotope

1. Introduction
Microbial sulfate reduction is an important metabolic activity in many petroleum
hydrocarbon (PHC)-contaminated aquifers (Lovley, 1997; Wiedemeier et al., 1999).
During dissimilatory sulfate reduction, bacteria reduce sulfate (S(V-) to sulfide (S(-II),
defined here as the sum of H 2 S, HS - and S 2 - ). Concurrently, PHC and other
indigenous organic compounds are oxidized and often mineralized to carbon dioxide
(CO2) and water. Thus, microbial sulfate reduction contributes to the removal of PHC
constituents from contaminated aquifers (Thierrin et al., 1993; Vroblesky et al., 1996;
Reinhard et al., 1997; Anderson and Lovley, 2000). Quantitative information on
microbial sulfate reduction is needed to assess its contribution to overall PHC removal at
a site.
Over the last decade, it has become increasingly apparent that in situ test methods are
required to accurately assess subsurface microbial activities (Gillham et al., 1990;
Madsen, 1991, 1998). Recently, single -well injection -withdrawal tests, which we call
"push-pull" tests, have been used for the in situ quantification of microbial activities in
PHC-contaminated aquifers (Istok et al., 1997; Reinhard et al., 1997; Schroth et al.,
1998). In a push-pull test, a prepared test solution that contains a non -reactive,
conservative tracer and one or more reactive solutes (reactants) is injected ("pushed")
into the aquifer through an existing well. During the following initial incubation period
(i.e., a rest phase without pumping), indigenous microorganisms consume reactants and
generate metabolic products. Thereafter, the test solution/groundwater mixture is
extracted ("pulled") from the same location. Rates of microbial activities are then
determined from an analysis of solute breakthrough curves obtained by measuring
concentrations of tracer, reactants and/or metabolic products at the injection/extraction
well during the extraction phase of the test (Haggerty et al., 1998; Snodgrass and
Kitanidis, 1998). So far, push-pull tests have been employed to quantify several
microbial processes in PHC-contaminated aquifers including aerobic respiration, denitri-
fication, sulfate reduction and methanogenesis (Istok et al., 1997), and degradation of
PHC constituents under nitrate- and sulfate -reducing conditions (Reinhard et al., 1997).
In addition, push-pull tests were used to assess spatial variability in aerobic respiration
and denitrification (Schroth et al., 1998). However, despite their efforts Istok et al.
(1997) were unsuccessful in determining rates of microbial sulfate reduction, as essen-
tially none of the injected SO4- was consumed during their tests, possibly due to the
relatively short incubation periods (- 7 h) employed.
Quantification of microbial sulfate reduction based on reactant (SO4 -) consumption
or product (S(-II)) formation may be obscured by concurrent abiotic transformations,
e.g., by dissolution/precipitation of gypsum (CaSO4, Stumm and Morgan, 1981), or by

M.H. Schroth et al. /Journal of Contaminant Hydrology 51 (2001) 179-195 181
precipitation of S(-II) as iron sulfides (Anderson and Lovley, 2000). As a tool to discern
microbial activity from abiotic transformations, stable isotope analyses have found
increasing application in recent years. For example, sulfur in natural environments
consists largely of two stable isotopes: 32 S (95.02% natural abundance) and 34 S (4.21
natural abundance) (Hoefs, 1997). Microbial sulfate reduction usually results in signifi-
cant isotope fractionation, i.e., an enrichment of 34S in unconsumed SO4- coupled to an
enrichment of 32S in produced S(-II) (Krouse, 1980; Clark and Fritz, 1997; Hoefs,
1997). Sulfur isotope fractionation in groundwater was previously observed in forest
hydrology studies (Robertson and Schiff, 1994; Alewell and Giesemann, 1996) as well
as in contaminated aquifers, e.g., at a waste disposal site (Bottrell et al., 1995). Thus,
sulfur isotope fractionation appears to be a valuable indicator for microbial sulfate
reduction in various environments. Unfortunately, little is known about sulfur isotope
fractionation in PHC-contaminated aquifers.
The main objective of this study was to evaluate the feasibility of push—pull tests in
combination with stable sulfur isotope analyses for the in situ quantification of microbial
sulfate reduction in a PHC-contaminated aquifer. Sulfate reduction was quantified based
on sulfate consumption observed during push—pull tests. In addition, stable sulfur
isotope analyses of extracted, unconsumed SO4 - and of extracted S(-II) were used to
determine isotope enrichment factors, which served as indicators for microbial sulfate
reduction.
2. Materials and methods
2.1. Field site description
The study was conducted in a heating oil -contaminated aquifer in Studen, Switzer-
land (Fig. la), which was characterized in detail by Bolliger et al. (1999). In 1993, a
spill from a leaking underground heating oil pipe was discovered at the site. Engineered
remediation was limited to the removal of free -phase heating oil (— 34 m3) by partial
excavation of contaminated soil and by pumping until 1996. At that time, engineered
remediation was terminated and monitored natural attenuation was selected as the
follow-up remediation strategy.
The 20- to 25-m-thick unconfined aquifer consists of unconsolidated glaciofluvial
outwash deposits with interbedded layers of poorly sorted silt, sand and gravel. The
ground water table is generally between 2 and 4 m below ground surface. Hydraulic
conductivity ranges from 1.0 X 10-4 to 9.3 X 10-3 m s I, porosity is estimated at 0.19,
and the average pore water velocity is ^- 0.4 m day-1 (Bolliger et al., 1999).
Push—pull tests described in this paper were conducted in monitoring well PS3,
which is located within the contaminant source zone (free -phase PHC present) (Fig. 1a).
Well PS3 is constructed of 11.5 cm I.D. polyvinyl chloride casing and partially
penetrates the aquifer to a depth of — 1 m below the ground water table. Compared to
the uncontaminated, upgradient well P20 (Fig. la), groundwater in PS3 exhibited
reduced conditions and contained up to 1 mg 1-' dissolved PHC (Bolliger et al., 1999).
Monitoring of geochemical parameters along a center flow line revealed that dissolved
oxygen (not shown) and nitrate were almost completely depleted and SO4- was

partially depleted by the time groundwater reached PS3 (Fig. lb, adopted from Bolliger
et al., 1999). Conversely, methane (CH4) concentrations increased considerably down -
gradient from PS3. Long-term monitoring for this site provided additional evidence that
PS3 is located within a transition zone where both sulfate -reducing and methanogenic
conditions are found (Bolliger et al., 2000).
2.2. Push—pull tests and sample collection procedures
Four push—pull tests, denoted PPT 1 through PPT4, were performed over a 9-month
period from August 1999 until April 2000. First, PPT1 was performed to evaluate

M.H. Schroth et al. /Journal of Contaminant Hydrology 51 (2001) 179-195 183
sulfate transport behavior during a push-pull test. Then PPT2, PPT3 and PPT4were
performed to repeatedly quantify rates of microbial sulfate reduction. For each push-pull
test, groundwater was first withdrawn from PS3 using a submersible pump (Gmndfos
MP-1, Grundfos Pumpen, Fallanden, Switzerland) and collected in 500-1 plastic carboys.
Test solutions were then prepared by adding bromide (Br-, prepared from KBr, Fluka,
Buchs, Switzerland) as non -reactive, conservative tracer and SO4 - (prepared from
K2 SO4 Fluka) as reactant to achieve final concentrations of 0.5 mM Br- and 1.0 or 2.0
mM SO4- (Table 1). In PPT2, PPT3 and PPT4, the carboys were continuously sparged
with nitrogen gas to minimize 02 dissolution from air into test solutions during
preparation and subsequent injection.
For each push-pull test, injection of a specified volume of test solution into PS3
began at time t = 0 h and was completed within 0.92 to 2.83 h using gravity drainage
(Table 1). In PPT1, continuous extraction began 1.1 h after the injection was terminated.
Longer initial incubation periods were used in PPT2, PPT3 and PPT4 before continuous
extraction was initiated in PPT2 and stepwise extraction over four consecutive days
(batches of 200 to 300 1 each per day) was employed in PPT3 and PPT4. In this fashion,
we extracted between 380 and 1100 1 of test solution mixed with native groundwater in
each test at nearly constant flow rates. Total test duration varied from 4.1 h in PPT1 up
to 119.9 h in PPT3 (Table 1).
Water samples for chemical/isotope analyses were obtained during the collection of
groundwater in carboys (background concentrations), during the injection of test solu-
tions (injection concentrations), and at regular intervals during the extraction phase of
the push-pull tests. Samples for Br- and SO4- were filtered in the field using 0.45-µm
polyvinylidenefluoride filters (Millipore, Bedford, USA) and stored in 12-m1 plastic
vials. Samples for alkalinity and pH were collected without headspace in 117-m1 serum
bottles using butyl rubber stoppers. All samples were stored at 4°C prior to analysis.
Samples collected for dissolved 02, S(-II) and ferrous iron (Fe(II)) determination were
analyzed immediately in the field (see below), as was groundwater temperature using an
appropriate electrode (Cyberscan pH100, Eutech Cybernetics, Singapore) fitted to a flow
cell.
Samples for sulfur isotope measurements of SO4 - (PPT2-PPT4) were collected in
1-1 glass bottles acidified with 2 ml of 32% HCl (Fluka). Sulfate was subsequently
precipitated as BaSO4 by replacing 10 ml of sample with 10 ml of a 1.2-M BaC12

solution. Samples for sulfur isotope measurements of S(-II) (PPT4 only) were collected
in 25-1 plastic carboys with 5 1 of headspace. Immediately after collection, samples were
acidified using 180 ml of 1 M HC1 and vigorously sparged with nitrogen gas for at least
30 min. During sparging, S(-II) was precipitated as Ag, S in a gas trap. The trap
contained 40 ml of 12.75 mM AgNO3 buffered at pH = 4 using 100 mM acetic acid/20
mM sodium acetate (Moncaster and Bottrell, 1991).
2.3. Analytical methods
Bromide and SO4 - concentrations were determined using a DX-100 ion chromato-
graph system equipped with a conductivity detector (Dionex, Sunnyvale, CA, USA).
Alkalinity was measured by potentiometric titration using Gran plots for graphical
determination of the end point (Stumm and Morgan, 1981) and pH was measured in the
laboratory with a MP 225 pH meter equipped with an InLab407 electrode (both
Mettler -Toledo, Schwerzenbach, Switzerland). Dissolved inorganic carbon (DIC, sum of
H2CO3, HCO3 and CO3-) concentrations were calculated from alkalinity and pH
(Stumm and Morgan, 1981). Dissolved 0,, S(-II) and Fe(II) were measured colorimetri-
cally using a DR/890 colorimeter (Hach, Loveland, CO, USA) following standard
protocols.
For stable sulfur isotope measurements, BaSO4 and Ag2 S were separately recovered
on 0.45-µm HVLP membrane filters (Millipore). After drying at 80°C, - 0.7 mg BaSO4
or Ag2 S were weighted in tin cups together with ^- 1.4 mg vanadium pentoxide (added
as catalyst). Sulfur isotope ratios (34S/32S) were subsequently measured on an Optima
mass spectrometer (Fisons, Middlewich, Cheshire, UK) coupled in continuous -flow to
an elemental analyzer (Carlo Erba Instruments, Milan, Italy). The system was calibrated
using international standards IAEA NZ1, IAEA NZ2, and NBS127 (IAEA, 1995).
Analytical reproducibility of the measurements was ± 0.3%0. Isotope data are reported in
the conventional 8-notation relative to the Vienna -Canyon Diabolo Troilite (V-CDT)
standard using:
834S (%0) -
2.4. Determination of first -order rate coefficients
First -order rate coefficients for sulfate reduction were determined from sulfate
consumption using the method of Haggerty et al. (1998). This method is based on an
analysis of tracer and reactant transport in the alternating diverging/converging radial
flow field surrounding a monitoring well during a push-pull test. The method assumes
that the injected reactant is transformed within the aquifer according to the first -order
type reaction dCr/dt = -kCr, where Cr is the reactive solute concentration and k is the
rate coefficient. The method also assumes that the injected test solution is well mixed
within the aquifer and that the advection-dispersion-sorption transport properties of

M.H. Schroth et al. /Journal of Contaminant Hydrology 51 (2001) 179-195 185
tracer and reactant are similar. With these assumptions, the rate coefficient may be
determined from (Haggerty et al., 1998):
( Cr* (t*) (1-e-kr;,u)
In Ctr ( *) t = 1n kt kt*(2)
n�
where C * is relative concentration (i.e., measured concentration divided by the concen-
tration in the injected test solution), subscripts r and tr denote reactant and tracer,
respectively, t * is time elapsed since the end of the test solution injection, and tini is
duration of the test solution injection. Hence, a plot of ln(Cr* /C,*) versus t * generates
a straight line with a slope - k and an intercept ln[(1 - e-k`Ini)/ktini)]. A nonlinear
least -squares routine was used to fit Eq. (2) (both slope and intercept) to experimental
breakthrough data to obtain estimates of first -order rate coefficients for sulfate reduction.
The 95% confidence interval for k (k ± 2 crk) was computed from the variance of the
estimated k, o-k2 using (Schroth et al., 1998):

with i = 1 to n, where n is the total number of observations, and o-' is the variance of
errors in In (Cr* /C« ).
2.5. Determination of isotope enrichment factors
Sulfur isotope fractionation was quantified by computing isotope enrichment factors,
e (in %o). In a closed system, enrichment factors can be determined by fitting Rayleigh
distillation equations to experimental data (Mariotti et al., 1981). Specifically, enrich-
ment factors of extracted, unconsumed SO4 - and extracted S(-II) may be determined
from measured 834 S values using (Bottcher et al., 1999):
b34S(SO4-) = 634S(SO4-)0 + elnf (4)
834S(S(-II)) = 534S(SO4 )0 - e(.flnf)/(1 -f) (5)
where f is the fraction of extracted, unconsumed SO4-, and 534S(SO4-)0 is the initial
isotope composition of sulfate in the injected test solution.
3. Results and discussion
3.1. Push-pull tests
Breakthrough curves for Br- and SO4 - showed a gradual decline in C * as extracted
test solution was increasingly diluted with native groundwater during PPT1 (Fig. 2). In
addition, relative concentrations of SO4- and Br- were nearly identical throughout the
extraction phase. This indicates that SO4- transport behavior in general was similar to
that of Br- and that SO4- sorption to aquifer solids in particular was negligible during

186 M.H. Schroth et al. /Journal of Contatninant Hydrology 51 (2001) 179-195
PPT1 (Schroth et al., 2000). Thus, results from PPT1 confirmed the assumption of
similar transport behavior for tracer and reactant, which is required for the accurate
computation of rate coefficients in subsequent tests using the method of Haggerty et al.
(1998). Moreover, by the end of PPT1 78% of the injected Br- mass and 77% of the
injected SO4- mass was recovered (computed by integrating solute breakthrough curves
shown in Fig. 2). Recovery of similar relative solute masses clearly indicates that the
total test duration (4.1 h, Table 1) was sufficiently short to prevent notable SO4-
consumption during PPT1.
Extraction phase breakthrough curves for Br- and SO4- during PPT2, PPT3 and
PPT4 (Fig. 3) showed gradual declines in C * similar to that observed during PPT1 (Fig.
2). However, relative SO4- concentrations were smaller than relative Br- concentra-
tions during most of PPT2-PPT4 extraction phases, which indicated that sulfate was
consumed during those tests, presumably due to microbial activity. Relative concentra-
tions of SO4- slightly larger than those of Br- were only observed in samples collected
near the end of PPT2-PPT4 extraction phases (Fig. 3). This is due to SO4- contained in
native groundwater (- 0.03 mM at the time the tests were conducted), which was
extracted together with the injected test solutions. To account for SO4 - contained in
native groundwater, we computed corrected sulfate concentrations (` SO4 -) using Br -
breakthrough curves as a measure of dilution of test solution with native groundwater
and assuming constant SO4- background concentrations for each test (Schroth et al.,
1998). As a consequence, relative `SO4- concentrations were smaller than relative Br -
concentrations throughout PPT2-PPT4 extraction phases (Fig. 3). Note that in PPT1 no
correction of SO4- data was necessary due to the higher SO4- concentrations em-
ployed in this test.
During the extraction phases of PPT2, PPT3 and PPT4, we recovered between 25%
and 31% of the injected Br- mass and between 20% and 23% of the injected SO4-

mass. Differences between recovered relative Br- and SO4- masses (21.3 ± 7.2% on
average for PPT2-PPT4) illustrate that total test durations (Table 1) were sufficiently
long to allow notable sulfate consumption during these tests. Conversely, mass recovery
of injected Br- tracer in PPT2-PPT4 (25-31%) was poor compared to that in PPT1
(78%). This is likely due to longer test durations in PPT2-PPT4 (Table 1) in combina-
tion with a fairly high average pore water velocity (- 0.4 m day-1) at the site. Thus,
during PPT2-PPT4, a significant portion of test solution migrated beyond the radius of
influence of PS3. However, it is important to note that no complete tracer mass recovery
is required during push-pull tests for an accurate quantification of rate coefficients
(Haggerty et al., 1998; see next section).
Sulfide increased from background concentrations (9.3-16.8 µM) to maximum
concentrations ranging from 14.0 to 50.9 µM during PPT2-PPT4 extraction phases (not
shown). For each test, produced S(-II) mass was computed by integrating measured
S(-II) concentrations after they were corrected for background and injected test solution
S(-II) concentrations. Produced S(-II) mass recovered during PPT2-PPT4 ranged from
2.3 to 14.9 mmol, which is much less than expected based on measured SO4 -
consumption (41.4-50.0 mmol). Loss of produced S(-II) during our tests was presum-
ably due to FeS precipitation, as Fe(II) concentrations up to 59.1 µM were measured
during the extraction phases (solubility product for FeS(s) is Kso = 10 -181 at 25°C;
Stumm and Morgan, 1981). Increased Fe(II) concentrations are commonly encountered
within reduced zones of contaminated aquifers (e.g., Lovley, 1997; Lovley and Ander-
son, 2000), often rendering S(-II) data useless for the quantification of microbial sulfate
reduction.
Other geochemical parameters did not vary significantly during PPT2-PPT4 extrac-
tion phases (not shown). In particular, calculated DIC concentrations ranged from 11.1
to 13.2 mM during the extraction phases without an obvious trend and were even
slightly smaller than DIC background concentrations (13.3 to13.8 mM) in PS3. This is at
least in part due to somewhat smaller DIC injection concentrations (9.7 to 13.3 mM, due
to sparging of test solutions prior to and during injection) compared to DIC background
concentrations. Moreover, based on measured SO4- consumption and given the follow-
ing reaction stoichiometry (Bolliger et al., 1999):
1.37CH1 85 + SO4—+ 2H+- 1.37CO2 + H2S + 1.26H20 (6)
we would expect minimal DIC production during our tests (up to 68.5 mmol DIC in
1000 1 of extracted test solution) compared to DIC contained in test solutions and native
groundwater. Thus, DIC data obtained during our tests did not provide additional
information for the quantification/verification of microbial sulfate reduction. This result
contrasts results for DIC analyses performed across entire contaminated sites, which
often provide useful information on overall metabolic activities (e.g., Chapelle et al.,
1996; Bolliger et al., 1999; Hunkeler et al., 1999).
3.2. Quantification of microbial sulfate reduction
First -order rate coefficients for sulfate reduction were computed for PPT2, PPT3 and
PPT4 based on Br- and ° SO4- breakthrough data (Fig. 3) using the method of

188 M.H. Schroth et al. /Journal of Contaminant Hydrology 51 (2001) 179-195
Haggerty et al. (1998) (Fig. 4). Note that best fit lines in Fig. 4 are intentionally
extended to the y-axis intercept (not forced through the origin) as both slope and y-axis
intercept were fitted (Eq. (2)). Simultaneous fitting of slope and intercept effectively
forces k to be the same throughout an entire push-pull test, i.e., during injection as well
as during subsequent incubation and extraction. Also note that PPT2 results were
unamenable for display due to the different extraction mode used in that test. Computed
values of k ranged from 0.043 to 0.130 day-1 with 95% confidence intervals ranging
from 0.010 to 0.015 day-1 (Table 2). Thus, values of k varied by less than a factor of
four between the tests. On the other hand, variations in k were significant to the 95%

temperature at the time each test was conducted (Table 2). Specifically, values of k
increased with increasing temperature in our tests, which is the generally expected
response of microorganisms to changes in temperature within a specific interval suitable
for growth (Madigan et al., 2000). Conversely, some scatter in the experimental data are

obtained a values of 22.8 ± 3.4%o for PPT3 and 20.2 ± 5.5%o for PPT4 (Table 2). Note
that we were unable to compute `b34S(SO4-) data for PPT2 due to an unreliable
measurement of the background SO4- isotope composition for the time this test was
conducted. Consequently, no e value was computed for this test.
Enrichment factors computed for our tests agreed well with e values obtained by
others for microbial sulfate reduction in different environments, e.g., e values of 16%0

to 42%0 (Habicht and Canfield, 1997), 19%0 (Bottcher et al., 1999), and 21.4%o to 28%0
(Asmussen and Strauch, 1998). Moreover, s values we obtained were significantly
larger than those commonly observed during physical/chemical transformations of
SO4 - (Krouse, 1980), and they were within a range that is indicative for microbial
sulfate reduction (- 20%o to 40%0, Clark and Fritz, 1997). Hence, stable sulfur isotope
fractionation of extracted, unconsumed SO4 - provided strong evidence for microbial
sulfate reduction during our tests. On the other hand, the magnitude of sulfur isotope
fractionation depends on many environmental parameters (e.g., Clark and Fritz, 1997;
Bottcher et al., 1999). Thus, a fully quantitative interpretation of s values obtained in
natural systems such as PHC-contaminated aquifers, including the quantification of
reaction rate coefficients based on isotope enrichment factors (Aggarwal et al., 1997), is
not feasible to date. Consequently, we cannot unequivocally exclude the possibility that
a portion of injected SO4 may have been abiotically consumed during our tests.
However, inorganic sulfate reduction is usually not significant in ground waters (Clark
and Fritz, 1997), and, at least for PPT1, SO4- precipitation did not appear to play a
major role during the test (Fig. 2).
Concurrent to an increase in 534 S(SO4 ), a decrease in 834 S(S(-II)) was measured in
samples collected during the extraction phase of PPT4 (not shown). This would be
expected for a closed system, in which enrichment of 34S in unconsumed SO4- must
lead to a depletion of 34S in produced S(-II). However, due to the small quantity of
produced S(-II) recovered during the test and the relatively high S(-II) background
concentration in native groundwater (see above), computation of s was not straightfor-
ward in this case. Depending on the (unknown) composition of extracted S(-II)
(produced or background S(-II)), we computed hypothetical values of s by fitting Eq.
(5) to experimental data. Computed values of s ranged from 14.8 ± 2.7%0 (for the case
that samples were composed of produced S(-II) only) to 30.1 ± 6.5%0 (for the case that
samples were composed of 100% background S(-II) and variable amounts of produced
S(-II)). For the case that samples were composed of 50% produced/50% background
S(-II), we calculated s = 22.9 ± 5.4%0. The latter value of s in particular agreed well
with values of s calculated from cO34 S(SO4 ) data for PPT3 and PPT4 (Table 2), but an
unbiased comparison between the different s values was obviously impossible. Never-
theless, the general observation of isotope fractionation in extracted S(-II) during PPT4
provided additional qualitative evidence for microbial sulfate reduction.
4. Summary and conclusions
Microbial sulfate reduction was quantified in situ in a PHC-contaminated aquifer
based on sulfate consumption observed during single -well push-pull tests. In three
consecutive tests, calculated first -order rate coefficients for sulfate reduction varied by
less than a factor of four. These variations were attributed in part to observed differences
in groundwater temperature between the tests. However, variations in other parameters
such as e.g., substrate concentration and pH may also have contributed to differences in
measured rates of sulfate reduction between consecutive tests. Although some scatter in
the field data was observed, we were able to determine rate coefficients for sulfate

reduction with reasonable accuracy, as indicated by relatively small 95% confidence
intervals. Additional studies should be conducted at common field sites to compare rate
coefficients for sulfate reduction obtained by our method with those obtained by other in
situ methods such as, e.g., in situ microcosms.
We demonstrated that quantification and/or verification of microbial sulfate reduc-
tion based on metabolic product formation (S(-II), DIC) was not feasible during our
push-pull tests. On the other hand, we provided strong evidence for microbial sulfate
reduction during our tests using stable sulfur isotope analyses. From measured isotope
fractionation of extracted, unconsumed SO4 -, we computed enrichment factors that
suggested microbial activity as the major mechanism for SO4- consumption. Further
evidence for microbial sulfate reduction during one push-pull test was obtained from
stable isotope measurements of extracted S(-II), even though a straightforward analysis
of 534 S(S(-II)) data was hampered by the small quantity of produced S(-II) compared to
the high S(-II) background concentration. Further experiments will be required to
interpret computed isotope enrichment factors resulting from microbial sulfate reduction
in a more quantitative fashion. Nonetheless, push-pull tests combined with stable sulfur
isotope analyses proved useful for the in situ quantification of microbial sulfate
reduction in a PHC-contaminated aquifer.

ATTACHMENT E - INJECTION PROCEDURE AND EQUIPMENT
(1) Construction Plans & Materials
URS proposes to inject a magnesium sulfate solution (with bromide tracer) in two areas on the
Site; Sulfate Injection Area 1 and Sulfate Injection Area 2 (see attached map in Attachment H).
Two areas are proposed to evaluate the effectiveness in an area of predominately benzene
contamination and an area of both benzene and MTBE. Both areas will be similar in size with the
advancement of 7 to 12 borings per area. Spacing of the points will be in grid pattern (i.e. offset
rows with approximately 8 foot spacing between each point). Borings are to be advanced between
20 and 40 feet bgs. It is anticipated that a direct push technology (DPT) will be used as a delivery
platform. Due to the potential for weathered bedrock (saprolite), a direct -push vehicle capable of
turning an auger may be utilized. The probe injection point will be advanced to the specified
depth then the injection point will be uncovered. An injection manifold inclusive of quick
connect couplings, a ball valve, and a pressure gauge will be attached to the top of the DPT rods.
Concurrent with the DPT advancement an Epsom salt and bromide solution will be mixed with
potable water to a sulfate concentration of 2,000 mg/L and bromide concentration of up to 1,000
mg/L. Concentrations will be based on calculations and the first batch will be checked by
laboratory analysis.
(2) Operation Procedures
This is a temporary mobile system that is vendor supplied. General components consist of a
mixing tank, product pump, metering and measuring system and affiliated conveyance hose. The
application apparatus will include a diaphragm injection pump with controller able to modulate
flow to below 5 gpm. The Injection pressure will be monitored at the injection manifold through
pressure gauges
The mobile system will be equipped with tanks for mixing the injection solution. Municipal
water will be used for the solution mixing. The solution will be injected at ambient temperatures.
High pressure hose will extend from the mixing tank, to the injection pump, to the injection. A
pressure gauge, shut-off valves, and pressure bleed -off will also be installed in -line. Injection will
be performed using a diaphragm pump. Injection pressures may range from 50 to 300 psi and
injection flow rates may range from 5 to 36 gpm. The injection pressure will be monitored

continuously using a pressure gauge and the injection rate will be adjusted using the injection
pump and valves. After injection, the injection pump will be turned off and the shut-off valve
will be closed. The residual pressure in the formation will then be monitored.
(3) Diagrams & Figures
See the attached figure in Attachment H for proposed area(s) of injection and the references below
for injection area within the boring.
(4) Planned Injection Schedule
It is anticipated that the injections will take place in late August 2010. The injection points will
be installed using a Direct Push Technology drilling rig. It is anticipated that several points will
be installed at the same time and then injected solution delivered to several points at the same
time. It is anticipated that no more than a 4-5 foot section will be injected at a time then the DPT
will be advanced to the next 4-5 foot interval until the boring depth is complete. Each of the two
areas will be completed in approximately 5-8 days.

Groundwater samples will be collected from the wells specified above prior to injection and at
two weeks, one month, two months, and three months.

ATTACHMENT G — WELL DATA
The following Information was provided previously by Piedmont Geologic (August
19, 2005)
(1) Public Water Supply Systems
Based upon information provided by previous site consultants (G&E, 1998), 19 public
water supply (PWS) systems are located within an approximate 3-mile radius of the
facility. No PWS systems have been identified within a 1,500-foot radius of the facility.
(2) Private Water Supply Wells
CRA (2004) identified and located private water -supply wells within an approximately
1,500-foot radius of the facility using a portable global positioning system (GPS). Private
water well locations are shown relative to the current distribution of site groundwater
COCs on Figure 6. The current disposition of the wells, as described below, was
confirmed by Mr. Keith Lewis of TransMontaigne, the Southeast Terminals facility
manager, in January and February 2005.
Three private potable water wells are situated within a 1,500-foot radius of the facility
boundaries. Information regarding the potable water -supply wells is summarized as
follows.

Two properties within a 1,500-foot radius of the facility boundaries contain private
water -supply wells. However, these same properties are also connected to city water and

have water accounts with CMUD. Based on this condition, these wells are considered
non -potable water -supply well. Information regarding the non -potable water -supply

SECTIONTWO Background
2.1 SITE LOCATION AND DESCRIPTION
Maps showing the Site location area and layout are provided as Figure 1 and Figure 2,
respectively. The Site is located in the Paw Creek area of Charlotte, North Carolina, an area
predominantly occupied by petroleum terminal and light industrial facilities. The facility
occupies approximately 26 acres and is bordered by Old Mount Holly Road to the north, a bulk
fuel terminal to the east, vacant property (former National Oil terminal) to the west, and
undeveloped woods to the south. Railroad tracks operated by Piedmont and Northern Railroad
are located directly south of the facility property, beyond which is situated a Duke Power
transmission line right-of-way.
The Site is a bulk petroleum distribution terminal that has been in operation since the 1940s and
was formerly owned jointly by BP and TransMontaigne. From February 2006 until February 1,
2013, the facility was solely owned and operated by BP. On February 1, 2013, the facility was
sold to MPC, who is the current owner and operator. The facility contains 19 bulk fuel storage
aboveground storage tanks (ASTs) that are contained within earthen bermed areas and/or
excavated areas with earthen cut -banks. The tank number, current fuel type, and capacity for the
bulk fuel storage tanks are listed below. Note that 2015 AST construction activity is underway
and tank inventory will be revised in future reporting.

In addition to the bulk fuel storage tanks, the facility contains a terminal office building,
miscellaneous storage and warehouse buildings, nine process ASTs, three underground storage
tanks (USTs), a covered tanker truck loading rack, associated process piping, and underground
piping associated with a decommissioned dual -phase vacuum extraction (DPVE)
soil/groundwater remediation system which had operated at the facility and has since been
removed. The tanker truck loading rack is located near the northern border of the facility, with
access from Old Mount Holly Road.
Six of the process ASTs, ranging in size from 180 to 8,000 gallons, contain fuel additives. Two
10,000-gallon ASTs contain petroleum contact water. One 2,000-gallon AST contains mixed
("slop") products. The USTs consist of one 1,000-gallon wastewater UST (located at the sump
near tank 110), one 2,000-gallon used oil UST (located adjacent to two 10,000-gallon
underground oil/water separators), and one 2,000-gallon vapor recovery unit (VRU) moisture
separator UST. A total of seven USTs have been decommissioned at the terminal.
The Site underwent a modification between September and December 2008 to include ethanol
fuel storage, an expanded truck loading rack, and a driveway widening to accommodate the
expansion. Fuel lines were added beginning late 2009. AST modifications is ongoing in 2015.
The terminal is supplied with petroleum products from underground pipelines owned by Colonial
Pipeline Company (Colonial) and Plantation Pipe Line Company (Plantation). Two 14-inch
diameter feed lines from Colonial enter the facility below ground from the northwest corner. One
10-inch and one 12-inch feed line from Plantation enter the facility from the southwest corner.
Two abandoned 14-inch underground pipelines enter the facility from the west side near the
warehouse from the former National Oil terminal. These pipelines formerly supplied product to
the former National Oil terminal via the MPC terminal product manifold.
Onsite utilities primarily consist of aboveground process piping from the bulk storage tanks to
the truck loading rack, overhead electrical and telephone services, underground low -voltage
communication cables, stormwater drain lines, inactive DPVE system piping, and a septic
system located south of the terminal office. The Charlotte -Mecklenburg Utility Department

(CMUD) supplies potable water service to the facility, Duke Power provides overhead electrical
service to the facility, and Bell South provides overhead telephone service.
The area surrounding the loading rack, office, warehouse, and motor truck shop is paved with
concrete or asphalt. Grass areas exist on the north side of the property along Old Mount Holly
Road. Tank berms, access roads to the tank areas, and the area between the tank areas and the
office/loading rack area are graded with gravel.
Stormwater from the bulk fuel storage tank basins is discharged to a ditch in the southern portion
of the site under a facility National Pollutant Discharge Elimination System (NPDES) permit.
Stormwater from the loading rack containment area is collected in a 10,000-gallon AST and
treated/disposed offsite at licensed facilities. Tank bottom water is collected into tanker trucks
and treated/disposed offsite at licensed facilities.
In late 2014/early 2015 the site starting undergoing construction projects regarding ASTs piping
and stormwater. Updated figures and tables will be provided in subsequent reports to reflect
these changes.
2.2 SITE TOPOGRAPHIC AND GEOLOGIC/HYDROGEOLOGIC SETTING
The facility is situated on the crest and slope of a hill centered on Old Mount Holly Road.
Ground -surface elevations at the facility range from approximately 795 feet relative to mean sea
level (msl) at the northern border of the facility adjacent to Old Mount Holly Road to
approximately 740 feet msl at the southern border of the facility. South of Old Mount Holly
Road, surface drainage is south toward Paw Creek. North of Old Mount Holly Road, surface
drainage is north toward Long Creek.
The Site is located in the Piedmont physiographic province, which is characterized by
moderately level inter -stream areas separated by broad valleys. Bedrock in Charlotte, North
Carolina is mapped within the Charlotte Belt lithologic division of the Piedmont, which includes
mafic gneisses, amphibolites, metagabbros, and metavolcanic rocks. According to the Geologic
Map of North Carolina (North Carolina Geological Survey, 1985), bedrock beneath the facility
consists of metamorphosed quartz diorite or quartzite.
Competent bedrock in the Piedmont province is typically overlain by variable thicknesses of
saprolite and soil, collectively referred to as "overburden." Saprolite consists of rock that has
been subject to chemical weathering, removing up to 60% of the rock mass by solution, but not
affecting volume (Cleaves, 1974). Saprolite commonly retains relict structures from the parent
bedrock. Thicknesses of the overburden in the Piedmont typically range from 10 to 75 feet,
depending on rock composition and topographic setting (LeGrand, 2004).
Based on Site boring logs, subsurface materials at the Site consist of soil and saprolite
overburden, including silty/clayey sand, sandy clay/silt, and silt/clay, which overlie weathered

SECTIONTWO Background
and competent bedrock. Bedrock, meeting the description of metamorphosed quartz diorite
referenced above, has been encountered in Site borings at depths ranging from approximately 10
to 40 feet below grade and elevations ranging from approximately 729 to 774 feet above msl.
Groundwater in the Piedmont province occurs in the overburden under unconfined (i.e., water
table) conditions and in the underlying bedrock under both unconfined and confined conditions.
j Groundwater in the overburden occurs within pore spaces of the unconsolidated medium,
including relict bedrock structures (e.g., fractures, foliations, etc.). Due to the typically fine-
grained nature and low permeability of saprolite, the formation is not usually utilized for
groundwater production. Groundwater in the underlying bedrock occurs along zones of
secondary porosity, such as fractures, foliations, solution voids, etc. Most water -supply wells in
the Piedmont are completed in bedrock with surface casings extending through the overburden.
I
2.3 SITE MONITORING WELL NETWORK
The locations of Site groundwater monitoring and remediation wells are shown on Figure 2. Site
well construction details are listed in Table 1. The depths of Site monitoring and remediation
wells range from 7 to 57 feet below ground surface (bgs). Site monitoring wells are completed in
bedrock, weathered bedrock, or in saprolite and shallow overburden (i.e., water -table monitoring
wells).
In March 2015, the following wells were abandoned: ASO1, DW08, DW09, MP-06, PMW01,
PMW02, PMW03, PMW06, T02A, and T02. These wells were located in an area of a proposed
storm water pond. Replacement wells are to be installed in the 3rd quarter of 2015.
2.4 SUMMARY OF LIGHT NON -AQUEOUS PHASE LIQUID OCCURRENCE
Historically, LNAPL was removed from the site and spotty occurrences were detected on the
groundwater in only a few of the 60+ monitoring wells. The most recent notable occurrence of
LNAPL occurred during the summer of 2013 at MW48.
In June 2013, approximately 0.18 feet of LNAPL was detected as accumulating over a nine year
period of time in monitoring well MW48. As a result of the LNAPL detection, URS
implemented a program to remove the LNAPL with absorbent socks. When the absorbent
became stained/saturated with LNAPL, it was removed from the well and properly disposed.
Since increased monitoring began at MW48 in early 2014, measurable LNAPL was only
detected twice; in January 2014 (0.03 ft) and May 2014 (0.02 ft). Prior to the June 2013 sampling
event, LNAPL was last detected at monitoring well ES29 at 0.01 feet, during the December 2010
gauging event and prior to that, LNAPL was not measurable since 2005 (Appendix A).
During the June 2015 sampling event, LNAPL was not visibly detected in well MW48. An
absorbent sock was not replaced in well MW48.

to diffuse oxygen into groundwater without producing bubbles. The device is 1.6-inches in
diameter and 15-inches long (about the size of a small submersible pump) and fits into 2-inch
and larger diameter wells. Oxygen is delivered to the device from standard oxygen cylinders via
1/-inch diameter polyethylene tubing.
The ISOCTM technology is specifically intended for use as a barrier remediation technology. The
typical radius of influence ranges from approximately 20 to 30 feet for these ISOCTM devices.
Following startup of the ISOCTM system in November 2005, groundwater dissolved oxygen
(DO) concentrations have been measured in the ISOCTM wells and other surrounding monitoring
wells on a routine basis. On December 2, 2014 three of the wells were found to be flooded and
oxygen supply tubing was found to be damaged. In response, the system was shut down to allow
for ISOCTM system building demolition to allow for the proposed biosparge/soil vapor extraction
(SVE) system install scheduled for installation in 2015. The ISOCTM system building was
removed in May 2015.
A Corrective Action Plan (CAP) Addendum was submitted to NCDENR in June 2012 and
approved July 19, 2012. The CAP proposed a biosparge system to address dissolved
hydrocarbons. Installation began June 1, 2015.

SECTIONTHREE Semi -Annual Groundwater Sampling and Analysis
3.1 GROUNDWATER SAMPLING AND ANALYSIS METHODS
Groundwater sampling activities were conducted on June 2-4, 2015. Over 60 monitoring wells
were sampled according to the methods discussed below.
Prior to collecting groundwater samples, depth to groundwater was measured in the Site
monitoring wells utilizing an electric oil/water interface probe. Site groundwater elevation data
are presented in Table 2. Measurable LNAPL was not detected in any monitoring wells during
the June 2015 gauging event. Historical groundwater elevation data are presented as
Appendix A.
Following well gauging, groundwater samples were collected from the Site monitoring wells
utilizing the purge/sample method described as follows:
1. Temperature, pH, DO, and specific conductance measurements were collected in -
situ prior to purging activities. Two (2) wells, DW10 and ES26 were not sampled as
construction material or equipment prohibited access. Well MW55 was under water
and therefore not sampled.
2. Each monitoring well was purged of a minimum of three standing volumes of
groundwater, or until dry, utilizing new, disposable bailers and nylon rope or a
submersible pump and new poly tubing. New nitrile gloves were donned for each
well and the submersible pump was decontaminated both prior to initial use and
between monitoring wells to prevent cross -contamination.
3. Each groundwater sample was collected utilizing new, disposable bailers and nylon
rope. The sample was immediately decanted into pre -preserved laboratory supplied
containers and labeled with unique sample identifying information.
Groundwater samples collected from the monitoring wells during the June 2015 sampling event
were placed on ice in a cooler with temperature and trip blanks and submitted under standard
chain of custody protocol to Accutest Laboratories Gulf Coast located in Scott, Louisiana
(Accutest). The groundwater samples were analyzed for volatile organic compounds (VOCs),
including benzene, toluene, ethylbenzene, total xylenes (BTEX), methyl tert-butyl ether
(MTBE), 1-2 dichloroethane (1,2-DCA), isopropyl ether (IPE), and naphthalene utilizing SW-
846 Method 8260B, as shown on Table 3. Groundwater samples collected from well PMWO9
are analyzed for monitored natural attenuation (MNA) parameters according to Table 3.
3.2 GROUNDWATER SAMPLING AND ANALYSIS RESULTS
URS validated analytical results from the June 2015 groundwater monitoring event at the Site.
The data review was modeled after the USEPA Contract Laboratory Program (CLP) National
Functional Guideline (NFG) for Superfund Organic Methods Data Review (USEPA, 2008) and

USEPA CLP NFG for Inorganic Superfund Data Review (USEPA, 2010). Qualitative and
quantitative limitations associated with the analytical results were determined based on the
results of specific quality control (QC) criteria. Accuracy was determined from the review of
spike recoveries. Precision was based on the evaluation of laboratory and field duplicate results.
Representativeness was evaluated from the review of holding times and blank data. Sample
results have been qualified based on the results of the data review process. Qualified data are
valid and usable for their intended purpose. A copy of the data validation report is available
upon request.
Monitored natural attenuation parameters from select wells are presented in Table 4. A
summary of analytical sample results from the June 2015 sampling event is presented in Table
5. Copies of the laboratory analytical data and chain of custody forms are provided as
Appendix B. Historical analytical data are presented as Appendix C.
A groundwater elevation contour map based on June 2015 Site data is provided as Figure 5. As
shown on Figure 5, groundwater flow is generally to the south and generally consistent with
historical flow direction. June 2015 groundwater isoconcentration contour maps for benzene,
toluene, ethylbenzene, xylenes, MTBE, naphthalene, 1,2-DCA, and IPE are provided as
Figures 6 through 13, respectively. Graphs of groundwater COC concentrations versus time for
individual monitoring wells are presented as Appendix D.
3.3 CONCENTRATION VERSUS TIME TRENDS
The concentration versus time trend plots, included as Appendix D, were divided into five areas
for localized trend evaluation. The areas include: the truck loading rack area to the north, west
side of site, the east side of the terminal, the interior (lower parking lot), and the central or
downgradient portion of the Site. A map is included in Appendix D illustrating the wells and
areas evaluated. Laboratory results for 1,2-DCA and IPE are not graphed, but discussed where
relevant in this section, and included in Appendix C.
Truck -Loading Rack Area
• ES 13 COC concentrations have been decreasing with minor fluctuations since 2006.
In June 2015, there were no exceedances of the NC 2L Standard.
• Well ES 14 continues to show COC fluctuations with an overall decreasing trend.
COC concentrations remain below the NC 2L Standards, except benzene.
• ES29 (an upgradient well for the whole project site) COC concentrations remain
below the NC 2L Standards.
• DWO6 (the most upgradient bedrock screened well for the site) continues to indicate
the presence of MTBE above the NC 2L Standard; however, the overall trend is

SECTIONTHREE Semi -Annual Groundwater Sampling and Analysis
decreasing. The remaining COCs are below their respective NC 2L Standards. Refer
to Appendix C as DWO6 was not graphed.
West Side of Site
• After decreasing COC trends since the December 2013 sampling event for well
MW02, all COC concentrations increased in June 2015. Benzene and MTBE
concentrations were present in exceedance of their respective NC 2L Standards.
• All COC concentrations in MWO8 remain below the NC 2L Standards.
• Well MW19 continues to show COC fluctuations with an overall decreasing trend.
MTBE, benzene and naphthalene concentrations were present in exceedance of their
respective NC 2L Standard.
• Well MW36 continues to show COC fluctuations with an overall decreasing trend.
During the June 2015 sampling event, benzene, MTBE, and naphthalene
concentrations were still present in exceedance of their respective NC 2L Standards.
• Well MW39 continues to show COC fluctuations with an overall decreasing trend.
During the June 2015 sampling event, benzene was detected at a concentration
above the NC2L Standard.
• Well MW41 continues to exhibit fluctuations in COC concentrations with benzene
and naphthalene remaining above their respective NC 2L Standards. The overall
COC concentration trends are decreasing.
Interior Wells (lower parking lot and office building area)
• Well UW08 continues to indicate the presence of benzene, naphthalene and MTBE,
well above their respected NC2L Standards.
• Well MW51 has generally exhibited an overall stable and decreasing trend in COC
concentrations, historically. Concentrations of benzene, MTBE, naphthalene, and
1,2-DCA remain well above their respected NC 2L Standards.
• Well MW21 continues to indicate the presence of benzene, ethylbenzene, xylenes,
MTBE, and naphthalene above their respected NC 2L Standards, although COC
concentrations remain relatively stable since 2005.
East Side of the Site
• ES33, located up gradient of the groundwater permeable reactive barrier (PRB),
located just south of ASTs 116 and 117, has exhibited overall decreasing trends of
COCs since the mid-1990s. Concentrations of benzene, xylenes, MTBE, and
naphthalene remain above their respected NC 2L Standards.

5 SECTIONTHREE Semi -Annual Groundwater Sampling and Analysis
• ES34 is the monitoring well located farthest north on the east site of the site and is
considered an upgradient well. Concentrations detected from this well are likely
from an off -site source. The overall trends of the COCs detected in the groundwater
from this well are decreasing and have remained below the NC 2L Standards for
years.
• ES35 continues to show COC fluctuations with an overall decreasing trend since
1998. Refer to Appendix C as ES35 was not graphed.
• PMW09, the southernmost sampled monitoring well located down gradient of the
groundwater PRB, continued to exhibit concentrations below the NC 2L Standards
for all COCs.
Central / Downgradient Portion of the Site
• MTBE concentrations in DWO2 continue to exhibit an increasing trend since 2008,
which exceeds the NC 2L Standard. The elevated concentrations of MTBE in well
DWO2 are believed to be associated with elevated MTBE concentrations in the
upgradient ES28 area that started out at 1,000 µg/L in 1996 and steadily decreased to
160 µg/L in 2014 (Appendix C and Figure 10). Concentrations of benzene continue
to increase.
• From 1998 to 2015 concentrations of MTBE have consistently been in the range of
about 50 to 100 µg/L in DW03; above the NC 2L Standard. The COC 1,2-DCA
(Appendix C) has consistently been quantified slightly over the NC 2L standard (0.4
µg/L) ranging from <0.34 to 1.8 µg/L over the last decade. The remaining COCs are
below below the laboratory method detection limits.
• All COC concentrations in ES38 remain below the NC 2L Standards.
A second form of time trend evaluation is illustrated in the side -by -side comparison of historical
isoconcentration contour maps from the past five sampling events for benzene, MTBE,
naphthalene and 1,2-DCA included in Appendix E to visually aid in identifying the movement
and/or stabilization of the plumes. The following observations are presented:
Benzene Plume
• The Tank 118 plume located to the east side of the site remains similar to previous
sampling events.
• The plume in the northwestern portion of the site appears similar in size to previous
sampling events.
MTBE Plume

3-4

SECTIONTHREE Semi -Annual Groundwater Sampling and Analysis
• There is no significant change in the size of the Tank 118 plume located to the east
side of the site since December 2000. Contouring in June 2013 reflects the current
MTBE NC 2L Standard of 20 µg/L and additional wells sampled (i.e. PMW01).
Prior to 2010, PMW01 remained below the MTBE NC 2L Standard of 200 µg/L.
• The northwestern plume, as depicted in Appendix E, on Figure 2-MTBE, and
historical MTBE concentrations tabulated in Appendix C, indicate little change in
plume size or distribution since the 1990s.
• The plume near the truck loading rack has remained stable in size and associated
concentrations appear to be fluctuating with an overall decreasing trend especially at
DWO6 (site up gradient well; Appendix C). For example, MTBE was quantified at
11,000 µg/L in 1998 and has steadily decreased to 383 µg/L in 2015.
Naphthalene Plume
• The Tank 118 area naphthalene plume remained comparable to the past four
sampling events.
• Naphthalene concentrations at the northeastern property boundary in the vicinity of
ES40 continues to exceed the NC 2L. However, this well is located at the extreme
northeast corner of the site in an up gradient position inferring impacts are likely
from an off -site source.
1,2-DCA Plume
• The NC 2L Standard for 1,2-DCA is very low at 0.4 µg/L; therefore, the plume
shape easily changes based on seasonal fluctuations. With that being said, the 1,2-
DCA plumes on the MPC property have been consistently in the same areas for
many years.

SECTIONFOUR Conclusions and Recommendations
4.1 CONCLUSIONS
• Groundwater flow across the Site is generally toward the south, which is generally
consistent with historical data.
• In general, groundwater COC distributions across the site indicate that COCs have
fluctuated slightly during the recent groundwater monitoring events, with a
decreasing trend over the years.
• The ISOCTM interim groundwater treatment system was damaged and turned off in
December 2014 and permanently removed in May 2015.
• A biosparge system installation began in June 2015 with operations expected to begin
in Fall 2015.
• Due to construction, monitoring wells located in the southeast portion of the site were
removed. Replacement wells are being installed in Fall 2015.
4.2 RECOMMENDATIONS
URS recommends continued semi-annual groundwater monitoring. The next sampling event will
occur in December 2015 and will follow the proposed sampling plan as outlined in Table 3. A
system installation summary and revised figures and tables will be included in future reporting.

This table presents the results of the volatile organic analytes. Sample results have been qualified by
URS based on the results of the data review process, which is modeled after the USEPA Contract
Laboratory Program (CLP) National Functional Guidelines (NFG) for Superfund Organic Methods
Data Review (EPA, June 2008). All results reported in micrograms per Liter (µg/L).
NC Groundwater quality standards for the protection of the groundwater are specified in 15A NCAC 2L
.0200. A shaded cell with a bold border indicates the concentration is greater than the standard.

NOTE:
Elevated concentrations of MTBE have been observed in a few of the
wells within the 2013 and 2014 depiction of the elongated plume
dating back to 1999. Additional wells were sampled during the 2013
and 2014 sampling events; therefore, making the plume better
defined.
