B. EXECUTIVE SUMMARY
The purpose of this report is to evaluate the current status of groundwater quality at Lewis Service
Station (Incident No. 3701). Terracon completed this report to summarize the findings of
assessment activities performed on July 29, 2019. The site is located at 4733 Fallston Road in
Fallston, Cleveland County, North Carolina in an area developed as commercial. The site is
currently occupied by Cool Cycle, Inc.

Based on regulatory file review information, the site formerly operated two 1,000-gallon gasoline
USTs, one 1,000-gallon kerosene UST, and two aboveground storage tanks (ASTs) related to on-
site fueling operations. A potential release was discovered on December 27 and 28, 1994. The
suspected release was from the 1,000-gallon gasoline UST located near the southeastern corner of
the on-site building. Reportedly, the two 1,000-gallon gasoline USTs were abandoned in place and
the 1,000-gallon kerosene UST was removed from the site.

Terracon mobilized to the site on June 29, 2019 to conduct groundwater sampling. Prior to sample
collection, Terracon gauged the groundwater levels in monitoring wells MW-1 through MW-6, MW-8,
RW-1, and VMW-1. The groundwater level in well MW-7 was not measured due to an obstruction in
the well. During this sampling event, depth to groundwater in the monitoring wells ranged from
approximately 19.32 feet (well MW-5) to 20.68 feet (well MW-6) below ground surface (bgs). The
estimated direction of groundwater flow is to the northeast. Prior to sampling, each well was purged
a minimum of three well volumes. After allowing the water to recharge to 90% of its original water
column length, Terracon collected a sample from each well except for well MW-7. During this
sampling event, well MW-2 on the adjacent Stamey Store property to the east (incident No. 12004,
see Figure 2), was inadvertently sampled as well MW-7 for the Lewis Service Station release. Well
MW-7 had been covered by a parked vehicle. After the vehicle was moved, Terracon attempted to
sample well MW-7 but the well was damaged and could not be sampled.

Terracon also collected a water sample from water supply well WSW-4. Prior to sampling the water
supply well, water was allowed to flow from a spigot located at the building for approximately 15

minutes. The flow of water from the spigot was reduced when the sample was collected. The water
samples collected from the monitoring wells and water supply well were submitted for laboratory
analysis of volatile organic compounds (VOCs) by Standard Method 6200, including MTBE, IPE and
EDB.

According to the laboratory analytical report, EDB (57.6 micrograms per liter [µg/L]) was detected in
well MW-1 at a concentration that exceeds its Gross Contamination Level (GCL). Benzene, n-
propylbenzene, MTBE, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, toluene, naphthalene, and
total xylenes were detected at concentrations exceeding their respective 15A NCAC 2L standards in
well MW-1. Benzene, MTBE, naphthalene and 1,2-dichloroethane were detected in well VMW-1 at
concentrations that exceed their respective 2L standards. Benzene, EDB, n-propylbenzene, MTBE,
naphthalene, 1,2-dichoroethane and 1,2,4-trimethylbenzene were detected in well RW-1 above their
respective 2L standards. Various other petroleum constituents were detected in wells MW-1, MW-2,
VMW-1 and RW-1 at concentrations below their respective 2L standards. No constituents of
concern were detected in monitoring wells MW-3, MW-4, MW-5, MW-6 and MW-8 and water supply
well WSW-4 above the method detection limits (MDLs). The laboratory results reported for well
MW-7 (actually obtained from well SSMW-2, Figure 2) indicate low levels of petroleum constituents.

During this sampling event to evaluate to potential for remedial alternatives, Terracon collected
additional samples from monitoring wells MW-2, VMW-1 and RW-1 for analysis of natural
attenuation parameters including dissolved gases (ethane, ethene and methane), dissolved oxygen,
ferrous iron, nitrate, nitrite, sulfate and alkalinity. The three wells were also evaluated for
biodegradation potential using QuantArray-Petro to identify aerobic and anaerobic biodegradation
organisms. These results indicate wells VMW-1 and RW-1 contain microorganisms responsible for
aerobic biodegradation of BTEX and MTBE, specifically Methylibium petroleiphilum (PM1), Phenol
Hydroxylase (PHE), Toluene 2 Monooxygenase (RDEG), Toluene Ring Hydroxylating
Monooxygenases (RMO), and Ethylbenzene/Isopropylbenzene Dioxygenase (EDO). Well RW-1
contains the highest volume of microorganisms. Well RW-1 also contains Naphthalene
Dioxygenase (NAH), which is a microorganism responsible for aerobic biodegradation of PAHs and
alkanes; however, the population is small. Benzoyl Coenzyme A Reductase (BCR) and
Benzylsuccinate Synthase (BSS) are microorganisms responsible for anaerobic biodegradation of
BTEX, while Naphthylmethylsuccinate Synthase (MNSSA), Naphthalene Carboxylase (ANC) and
Alkylsuccinate Synthase (ASSA), microorganisms responsible for anaerobic biodegradation of PAHs
and alkanes were also found in wells VMW-1 and RW-1. Other bacteria detected in the wells
included Total Eubacteria (EBAC) and Sulfate Reducing Bacteria (APS).

Based on information obtained during the completion of these assessment activities, Terracon
provides the following conclusions and findings.

Free product was not encountered at the site.
EDB was detected in monitoring well MW-1 at a concentration that exceeds its GCL.

Benzene, n-propylbenzene, MTBE, EDB 1,2-dichloroethane, toluene, 1,2,4-trimethylbenzene,
1,3,5-trimethylbenzene, naphthalene, and total xylenes were detected in one or more wells (MW-1,
VMW-1 and RW-1) at levels above their respective 2L standards. Various other petroleum
constituents were detected in wells MW-1, MW-2, VMW-1 and RW-1 at concentrations below their
respective 2L standards. No constituents of concern were detected in monitoring wells MW-3,
MW-4, MW-5, MW-6 and MW-8 above the MDLs.
Groundwater flow direction at the site is to the northeast.
No constituents of concern were detected in water supply well WSW-4 above the MDLs.
Generally, constituent concentrations appear to be decreasing in wells MW-1, VMW-1 and RW-1.
Based on the results of the natural attenuation parameters, the environmental conditions within the
source area appear to be anaerobic with a sufficient population of microorganisms to promote
biodegradation of the petroleum contaminants which may be occurring due to the decreased
concentrations.
Based on the findings of our assessment activities, the following comments and recommendations are
provided for the site.
Terracon recommends contacting the property owner of well WSW-4 to request abandonment.
Terracon recommends the on-site wells be sampled on an annual basis.
Due to the apparent anaerobic environmental conditions, injection of an effective electron acceptor

C. SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to evaluate the current status of groundwater quality at the former
Lewis Service Station site. Terracon completed this report to summarize the findings of assessment
activities performed on July 29, 2019. The site is located at 4733 Fallston Road in Fallston,
Cleveland County, North Carolina (Figure 1). This Subsequent Monitoring Report was prepared for
the site in response to a request by Mr. Mark Petermann, NCDEQ Incident Manager with the
Division of Waste Management, State Lead Program.

The Subsequent Monitoring Report was prepared in general accordance with the 15A NCAC
2L.0115 regulations and the NCDEQ Underground Storage Tank (UST) Section Guidelines for
Assessment and Corrective Action for UST Releases, dated July 15, 2008, revised December 2013,
under the supervision of Mr. Christopher L. Corbitt, a North Carolina registered professional
geologist (North Carolina License No. 1015).

C.1 Site Setting
The site is located in an area primarily developed as commercial. A park is located on the adjacent
property to the north and Tropical Creations is located on the adjacent property to the south. The
site is bound to the east by Fallston Road and a residence is located on the adjacent property to the
west. Specific land uses are further described in Section C.6 below.

C.2 Release Summary
Based on regulatory file review information, the site formerly operated two 1,000-gallon gasoline
USTs, one 1,000-gallon kerosene UST, and two ASTs related to on-site fueling operations. A
potential release was discovered on December 27 and 28, 1994. The suspected release was from
the 1,000-gallon gasoline UST located near the southeastern corner of the on-site building.
Historical UST information is provided in Table 1.

C.3 Previous Investigations
Based on regulatory file review information, the site formerly operated two 1,000-gallon gasoline
USTs, one 1,000-gallon kerosene UST, and two ASTs related to on-site fueling operations. A
potential release was discovered on December 27 and 28, 1994. The suspected release was from
the 1,000-gallon gasoline UST located near the southeastern corner of the on-site building.
Reportedly, the two 1,000-gallon gasoline USTs were abandoned in place and the 1,000-gallon
kerosene UST was removed from the site.

In May 2016, Shield Engineering Inc. (Shield) conducted a 96-hour Mobile Multiphase Extraction
Event (MMPE) at on-site wells MW-1, VMW-1 and RW-1. Approximately 3,600 gallons of dissolved
phase impacted groundwater were recovered during the MMPE event. An estimated 32 gallons of
free product (gasoline) was removed from the site as vapor. A subsequent well sampling event on
June 14, 2016 indicated contaminant concentrations had generally decreased as a result of the
MMPE event. Constituent concentrations were below their respective GCLs but remained above
their respective 2L standards.

In August 2017, Terracon conducted a groundwater sampling event on wells MW-1, RW-1, and
VMW-1. Groundwater depths ranged from 26.60 feet (well RW-1) to 26.97 feet (well VMW-1) bgs.
Benzene was detected in well RW-1 above its GCL and various constituents were detected above
their respective 2L standards in wells VWM-1 and MW-1.

C.4 Water Supply Wells
Two water supply wells were identified within 1,500 feet of the source area as reported by Shield in
2016. Well WSW-4, located on the adjacent property to the west, is used to water vegetation in a
nearby park located north of the site. Well WSW-Cotton Gin, located between 500 and 1,000 feet
east of the source area, is reportedly used for washing vehicles and other machinery. Municipal

water is available in the area. Well information is summarized in Table 2. The approximate
locations of the identified water supply wells are shown on Figure 3.

C.5 Surface Water
An unnamed tributary of Buffalo Creek is located approximately 1,100 feet northeast and down-
gradient of the site. Surface waters are depicted on Figure 1.

C.6 Land Use Information
The former gas station site is presently occupied by Cool Cycle, Inc., a motorcycle repair shop. The
front of the property contains the former dispenser island beneath an overhead canopy structure.
Two apparent storage buildings are located at the rear (west) of the property. Terracon was not
provided access to the rear of the property; however, minor oil stains and typical motorcycle repair
operations were observed within the on-site building. The adjoining properties to the east, across
Fallston Road and south are commercial businesses. The adjoining property to the west is
developed as a single-family residence and a storage building. The adjoining property to the north is
a city park. The site and surrounding properties are depicted in Figures 1 and 2.

D. ASSESSMENT INFORMATION
D.1 Site Geology and Hydrogeology
The following resources were reviewed to evaluate site-specific geological and hydrogeological
characteristics.

Lawndale, North Carolina, USGS 7.5-minute topographic map, dated 2002 (Figure 1).
Geologic Map of North Carolina, dated 1985.
The Geology of the Carolinas, Carolina Geological Society Fiftieth Anniversary Volume, edited by
J. Wright Horton, Jr., and Victor A. Zullo, The University of Tennessee Press, dated 1991.

The site is located within the Inner Piedmont Belt of the Piedmont Physiographic Province. The
Piedmont Physiographic Province generally consists of low to medium elevation, rounded hills and
long rolling northeast to southwest trending ridges with incised creeks and river channels.
Underlying bedrock in the site area consists of biotite gneiss and schist.

In-place chemical and physical weathering of parent rocks typically form residual soils in the
Piedmont region. Weathering is facilitated by the presence of fractures, joints, and less resistant

minerals in the rock. In areas not altered by erosion, alluvial deposition or the activities of man, the
typical residual soil profile consists of clay-rich unconsolidated materials at the surface, transitioning
to sandy silts and silty sands at depth. Typically, the boundary between soil and rock is not sharply
defined. This transitional zone is termed “partially weathered rock” or saprolite. Information obtained
from the Web Soil Survey for Cleveland County, depicts soils at the site as Cecil-Urban land
complex (CeB).

In the Piedmont, groundwater generally occurs in pore spaces within soils and in the structural
features present in the underlying rock (i.e. joints, fractures, and faults). Recharge to the water table
is primarily by precipitation infiltrating the surficial soils and percolating downward under the
influence of gravity to the water table (vadose zone). Typically, the water table is not a level surface,
but a subdued reflection of the land surface. The depth to the water table is not consistent and is
dependent upon several factors that include the amount of rainfall, permeability of the soil, the
extent of fracturing in the underlying rock and the influences of groundwater pumping. Groundwater
typically flows in directions parallel to the ground surface and under the influence of gravity, migrates
to discharge points such as surface water features, the toes of slopes or natural springs.

Fluctuations in the depth of the water table can be expected depending on variations in precipitation,
surface water run-off and other factors not evident at the time of our subsurface exploration.
Normally, the highest levels of the water table occur in late winter and spring and the lowest levels
occur in the late summer and fall. Based on an interpreted groundwater flow direction from
topographic data, groundwater is expected to flow to the northeast from the site.

Free product was not encountered at the site.

D.2.2 Groundwater Sampling Activities
Terracon mobilized to the site on June 29, 2019 to conduct groundwater sampling. Prior to sample
collection, Terracon gauged the groundwater levels in monitoring wells MW-1 through MW-6, MW-8,
RW-1, and VMW-1. The groundwater level in well MW-7 was not measured due to an obstruction in
the well. During this sampling event, depth to groundwater in the monitoring wells ranged from
approximately 19.32 feet (well MW-5) to 20.68 feet (well MW-6) below ground surface (bgs). The
estimated direction of groundwater flow is to the northeast. Prior to sampling, each well was purged
a minimum of three well volumes. After allowing the water to recharge to 90% of its original water
column length, Terracon collected a sample from each well except for well MW-7. During this

of the monitoring wells are shown on Figure 2. Copies of Terracon’s field notes are included in
Appendix B. Current and historical groundwater depth measurements are provided in Table 4.

The groundwater samples were placed in laboratory-supplied glassware, labeled and stored in an
ice-packed cooler. The samples, along with chain-of-custody documentation, were delivered to Pace
Analytical Services, Inc. in Huntersville, North Carolina for analysis of VOCs by Standard Method
6200B, including MTBE, IPE and EDB. Additionally, monitoring wells MW-2, VMW-1 and RW-1
were analyzed for natural attenuation parameters including dissolved gases, ferrous iron, nitrate,
nitrite, sulfate and alkalinity.

Terracon also submitted groundwater samples from wells MW-2, VMW-1 and RW-1 to Microbial
Insights for evaluation of biodegradation potential using QuantArray®-Petro to identify aerobic and
anaerobic biodegradation organisms. The process quantifies specific functional genes responsible
for both aerobic and anaerobic biodegradation of BTEX, PAHs, and a variety of short and long chain
alkanes, and the potential of contaminant biodegradation.

D.2.3 Analytical Results
Groundwater Monitoring Wells
According to the laboratory analytical report, EDB (57.6 µg/L) was detected in well MW-1 at a
concentration that exceeds its GCL. The following constituents were detected at concentrations that
exceed their respective 2L standards in well MW-1; benzene (509 µg/L), n-propylbenzene (109
µg/L), MTBE (191 µg/L), 1,2,4-trimethylbenzene (1,640 µg/L), 1,3,5-trimethylbenzene (415 µg/L),
toluene (2,750 µg/L), naphthalene (387 µg/L) and total xylenes (3,190 µg/L).

The following constituents were detected in well VMW-1 at concentrations that exceed their
respective 2L standards; benzene (270 µg/L), MTBE (1,060 µg/L), naphthalene (91 µg/L) and 1,2-
dichloroethane (23.1 µg/L).

The following constituents were detected in well RW-1 above their respective 2L standards;
benzene (464 µg/L), EDB (8.5 µg/L), n-propylbenzene (107 µg/L), MTBE (217 µg/L), naphthalene
(226 µg/L), 1,2-dichloroethane (6.9 µg/L) and 1,2,4-trimethylbenzene (1,030 µg/L).

Various other constituents were detected in wells MW-1, MW-2, VMW-1 and RW-1 at
concentrations below their respective 2L standards. No constituents of concern were detected in
monitoring wells MW-3, MW-4, MW-5, MW-6 and MW-8 and water supply well WSW-4 above the
MDLs. The laboratory results reported for well MW-7 (actually obtained from well SSMW-2, Figure
2) indicate low levels of petroleum constituents. The groundwater analytical results are summarized
in Table 3 and are depicted on Figure 5. A copy of the laboratory analytical report is provided in
Appendix A.

QuantArray®-Petro
Terracon submitted groundwater samples from wells MW-2, VMW-1 and RW-1 to Microbial Insights
for the evaluation of biodegradation potential using QuantArray®-Petro. The analytical data
indicated the following microorganisms in each well:

 MW-2: Toluene 2 Monooxygenase/Phenol Hydroxylase (RDEG) [1.7 J cells/mL],
Methylibium petroleiphilum (PM1) [318 cells/mL], Naphthalene Dioxygenase (NAH) [144
cells/mL], and Total Eubacteria (EBAC) [118,000 cells/mL]
 VMW-1: Phenol Hydroxylase (PHE) [2,650 cells/mL], RDEG [31,500 cells/mL], Toluene Ring
Hydroxylating Monooxygenases (RMO) [2,130 cells/mL], PM1 [23,000 cells/mL], Alkane
Monooxygenase (ALK) [0.80 J cells/mL], Benzoyl Coenzyme A Reductase (BCR) [168
cells/mL], Benzylsuccinate Synthase (BSS) [154 cells/mL], Naphthylmethylsuccinate
Synthase (MNSSA) [45 cells/mL], Naphthalene Carboxylase (ANC) [1,750 cells/mL],
Alkylsuccinate Synthase (ASSA) [43.1 cells/mL], EBAC [10,700,000 cells/mL], and Sulfate
Reducing Bacteria (APS) [51,200 cells/mL]
 RW-1: PHE [2,350 cells/mL], RDEG [33,100 cells/mL], RMO [7,050 cells/mL],
Ethylbenzene/Isopropylbenzene Dioxygenase (EDO) [253 cells/mL], PM1 [31,500 cells/mL],
NAH [28,300 cells/mL], BCR [546 cells/mL], BSS [1,440 cells/mL], ANC [85.5 cells/mL],
ASSA [69.5 cells/mL], EBAC [20,700,000 cells/mL], and APS [46,600 cells/mL].

These results indicate wells VMW-1 and RW-1 contain microorganisms responsible for aerobic
biodegradation of BTEX and MTBE, specifically PM1, PHE, RDEG, RMO and EDO. Well RW-1
contains the highest volume of microorganisms. Well RW-1 also contains NAH, which is a
microorganism responsible for aerobic biodegradation of PAHs and alkanes; however, the
population is small. BCR and BSS are microorganisms responsible for anaerobic biodegradation of
BTEX, while ANC and ASSA are microorganisms responsible for anaerobic biodegradation of PAHs
and alkanes. A copy of the QuantArray-Petro report is provided in Appendix A.

Natural Attenuation Parameters
Terracon also sampled the groundwater in wells MW-2, VMW-1 and RW-1 for natural attenuation
parameters including dissolved gases (ethane, ethene, and methane), dissolved oxygen, ferrous
iron, nitrate, nitrite, sulfate and alkalinity.

According to the Wisconsin Department of Natural Resources, the rate of biodegradation depends
on the amount of contaminant released, the rate of movement through the soils and groundwater,
and the presence of appropriate environmental conditions. The extent of biodegradation is usually
controlled by the availability of electron acceptors (e.g., oxygen, nitrate, iron and sulfate).
Microorganisms use these “acceptors” to breathe in anaerobic situations. Oxygen is readily depleted
in groundwater so that aerobic degradation processes are limited to the fringes of a contaminant
plume while anaerobic processes, which account for most biodegradation activity, occur within the
contaminant plume.

Each analyte is used for a specific purpose in the biodegradation process and changes with
increased biological activity. The following is a list of parameters that Terracon assessed in the field
and those analyzed in the laboratory, along with their purpose in the process and resulting change
with increased biological activity:

 Field Parameters
 Redox Potential – Important control on biological activity in the subsurface, decreases
with increased activity
 pH – Biological activity is pH sensitive and pH can remain the same or decrease with
increased activity

 Analytes
 Methane – Metabolic by-product of methanogenesis, increases as activity increases
 Carbon Dioxide – Produced during biodegradation, increases as activity increases
 Oxygen – A terminal electron acceptor in aerobic conditions, decreases with increased
activity
 Nitrate – Terminal electron acceptor in anaerobic conditions, decreases with increased
activity
 Nitrite – Terminal electron acceptor in anaerobic conditions, decreases with increased
activity
 Alkalinity – Measures the buffering capacity of the groundwater and is affected by the
carbon dioxide produced during biodegradation, increases as activity increases
 Sulfate – Terminal electron acceptor in anaerobic conditions, decreases with increased
activity
 Ferrous Iron – Metabolic by-product of iron reduction, increases as activity increases

The analytical results indicated the following results:

 MW-2

MW-4, MW-5, MW-6 and MW-8 above the MDLs.
Groundwater flow direction at the site is to the northeast.
No constituents of concern were detected in water supply well WSW-4 above the MDLs.
Generally, constituent concentrations appear to be decreasing in wells MW-1, VMW-1 and RW-1.
Based on the results of the natural attenuation parameters, the environmental conditions within the
source area appear to be anaerobic with a sufficient population of microorganisms to promote
biodegradation of the petroleum contaminants which may be occurring due to the decreased
concentrations.

Based on the findings of our assessment activities, the following comments and recommendations are
provided for the site.
Terracon recommends contacting the property owner of well WSW-4 to request abandonment.
Terracon recommends the on-site wells be sampled on an annual basis.
Due to the apparent anaerobic environmental conditions, injection of an effective electron acceptor
to enhance the growth and activity of the in-situ microorganism populations.

The QuantArray®-Petro Approach
Comprehensive evaluation of biodegradation potential at petroleum impacted sites is inherently problematic due to two factors:
(1)Petroleum products are complex mixtures of hundreds of aliphatic, aromatic, cyclic, and heterocyclic compounds.
(2)Even for common classes of contaminants like benzene, toluene, ethylbenzene, and xylenes (BTEX), biodegradation can pro-
ceed by a multitude of pathways.
The QuantArray®-Petro has been designed to address both of these issues by providing the simultaneous quantification of the
specific functional genes responsible for both aerobic and anaerobic biodegradation of BTEX, PAHs, and a variety of short and long
chain alkanes.
Thus, when combined with chemical and geochemical groundwater monitoring programs, the QuantArray®-Petro allows site
managers to simultaneously yet economically evaluate the potential for biodegradation of a spectrum of petroleum hydrocarbons
through a multitude of aerobic and anaerobic pathways to give a much clearer and comprehensive view of contaminant biodegrada-
tion.
The QuantArray®-Petro is used to quantify specific microorganisms and functional genes to evaluate aerobic and anaero-
bic biodegradation of the following classes of compounds present in petroleum products:
BTEX and MTBE Naphthalene and PAHs Alkanes/TPH
Toluene dioxygenase (TOD)
and monooxygenase (RMO,
RDEG, PHE, TOL) genes for
aerobic BTEX biodegradation
Includes two groups of naphtha-
lene dioxygenase genes (NAH,
PHN) for aerobic biodegradation
The n-alkanes are a substantial
portion of petroleum products
Includes MTBE utilizing strain
Methylibium petroleiphilum PM1
and TBA monooxygenase
Naphthylmethylsuccinate synthase
(MNSSA) for anaerobic biodegra-
dation of methyl-naphthalenes
The QuantArray®-Petro includes
quantification of alkane monooxy-
genase genes (ALK and ALMA)Benzylsuccinate synthase (BSS)
for anaerobic biodegradation of
toluene, ethylbenzene, and xylenes Naphthalene carboxylase
(ANC) initiates the only
known pathway for anaerobic
naphthalene biodegradation
Also includes quantification of
alkylsuccinate synthase (assA)
genes to evaluate anaerobic
biodegradation of alkanes
Benzene carboxylase (ABC) for
anaerobic benzene biodegradation]
How do QuantArrays®work?
The QuantArray®-Petro in many respects is a hybrid technology combining the highly parallel detection of mi-
croarrays with the accurate and precise quantification provided by qPCR into a single platform. The key to
highly parallel qPCR reactions is the nanoliter fluidics platform for low volume, solution phase qPCR reactions.

How are QuantArray®results reported?
One of the primary advantages of the QuantArray®-Petro is the simultaneous quantification of a broad spectrum of different
microorganisms and key functional genes involved in a variety of pathways for hydrocarbon biodegradation. However, highly
parallel quantification combined with various metabolic and cometabolic capabilities of different target organisms can complicate
data presentation. Therefore, in addition to Summary Tables, QuantArray®-Petro results will be presented as Microbial Population
Summary and Comparison Figures to aid in the data interpretation and subsequent evaluation of site management activities.
Types of Tables and Figures:
Figure presenting the concentrations of QuantArray®-
Petro target gene concentrations (e.g. toluene dioxy-
genase) relative to typically observed values.
Tables of target population concentrations grouped
by biodegradation pathway and contaminant type.
Depending on the project, sample results can be presented
to compare changes over time or examine differences in mi-
crobial populations along a transect of the dissolved plume.

Interpretation
The overall purpose of the QuantArray®-Petro is to give site managers the ability to simultaneously yet economically evaluate
the potential for biodegradation of a spectrum of contaminants found in petroleum products through a multitude of aerobic and
anaerobic pathways to give a much more clear and comprehensive view of contaminant biodegradation. The following discussion
describes interpretation of results in general terms and is meant to serve as a guide.
Aerobic Biodegradation - Benzene Toluene, Ethylbenzene, and Xylenes (BTEX):At sites impacted by petroleum products,
aromatic hydrocarbons including BTEX are often contaminants of concern. Aerobic biodegradation of aromatic hydrocarbons has
been intensively studied and multiple catabolic pathways have been well characterized. The substrate specificity of each pathway
(range of compounds biodegraded via each pathway) is largely determined by the specificity of the initial oxygenase enzyme.
The QuantArray®-Petro includes a suite of assays targeting the initial oxygenase genes of the known pathways for aerobic BTEX
biodegradation.
Toluene/Benzene Dioxygenase (TOD):Toluene/benzene dioxygenase (TOD) incorporates both atoms of molecular oxygen
into the aromatic ring. Although commonly called toluene dioxygenase, the substrate specificity of this enzyme is relaxed,
allowing growth on toluene and benzene along with co-oxidation of a variety of compounds including ethylbenzene,o-xylene,
m-xylene, and trichloroethene (TCE) when expressed.
Toluene/Benzene Monooxygenases (RMO/RDEG) and Phenol Hydroxylases (PHE):The next three known pathways for
aerobic biodegradation of toluene (as well as benzene and xylenes) involve two steps: (1) an initial oxidation mediated
by a toluene monooxygenase and (2) a second oxidation step catalyzed by a phenol hydroxylase. In these pathways, the
toluene monooxygenases have been referred to as “ring hydroxylating monooxygenases” because they initiate biodegradation
of toluene by incorporating oxygen directly into the aromatic ring rather than at a methyl group. The ring hydroxy-
lating monooxygenases (RMOs) can be further described as toluene-2-monooxygenases, toluene-3-monooxygenases, or
toluene-4-monooxygenases based upon where they attack the aromatic ring.
In General, phenol hydroxylases (PHE) catalyze the continued oxidation of phenols produced by RMOs. However, the
difference between toluene monooxygenases (RMOs) and phenol hydroxylases (PHEs) is not absolute in terms of substrate
specificity and catabolic function. For example, the TbmD toluene/benzene-2-monooxygenase [1] may be responsible for both
the initial and second oxidation step [2].
The RMO, RDEG, and PHE assays target groups of genes encoding enzymes which perform the critical first and/or
second steps in the aerobic biodegradation of BTEX compounds. In general terms, the RMO assay quantifies families of
toluene-3-monooxygenase and toluene-4-monooxygenase genes. The RDEG assay is used to quantify groups of toluene-
2-monooxygenase and phenol hydroxylase genes. Similarly, the PHE assay targets phenol hydroxylase genes and several
benzene monooxygenase genes which catalyze both oxidation steps.
Toluene/Xylene Monooxygenase (TOL):The final known pathway for aerobic toluene biodegradation involves initial
monooxygenase attack at the methyl group by a toluene/xylene monooxygenase.

Ethylbenzene Dioxygenase (EDO):Similar to TOD, this group of aromatic oxygenases exhibits relatively broad specificity and
is responsible for aerobic biodegradation of alkylbenzenes including ethylbenzene and isopropylbenzene or cumene [3].
Biphenyl Dioxygenase (BPH4):In environmental restoration, biphenyl dioxygenases are best known for cometabolism of
polychlorinated biphenyls (PCBs). However, this subfamily includes benzene [4] and isopropylbenzene [5] dioxygenases from
Rhodococcus spp.
Aerobic Biodegradation - MTBE and TBA:With increased use in the 1990s, the fuel oxygenate methyl tert-butyl ether (MTBE) has
become one of the most commonly detected groundwater contaminants at gasoline contaminated sites. Pure cultures capable of
utilizing MTBE as a growth supporting substrate have been isolated [6] and aerobic biodegradation of MTBE and the intermediate
tert-butyl alcohol (TBA) has been reasonably well characterized. The QuantArray®-Petro includes quantification of two gene targets
to assess the potential for aerobic biodegradation of MTBE and TBA.
Methylibium petroleiphilum PM1 (PM1):One of the few organisms isolated to date which is capable of utilizing MTBE and TBA
as growth supporting substrates [6].
TBA Monooxygenase (TBA):Targets the TBA monooxygenase gene responsible for oxidation of TBA by Methylibium
petroleiphilum PM1 [7].
Aerobic Biodegradation - Naphthalene and Other PAHs:
Naphthalene Dioxygenase (NAH):Naphthalene dioxygenase incorporates both atoms of molecular oxygen into naphthalene
to initiate aerobic metabolism of the compound. However, the broad substrate specificity of naphthalene dioxygenase has
been widely noted. When expressed, naphthalene dioxygenase is capable of catalyzing the oxidation of larger PAHs like
anthracene, phenanthrene, acenaphthylene, fluorene, and acenaphthene. For a more comprehensive list of reactions mediated
by naphthalene dioxygenases, see the University of Minnesota Biocatalysis/Biodegradation Database. (http://eawag-
bbd.ethz.ch/naph/ndo.html, [8]).
Phenanthrene Dioxygenases (PHN):The PHN assays quantify phenanthrene/naphthalene dioxygenase genes from a di-
verse collection of microorganisms including Pseudomonas,Burkholderia,Sphingomonas, and Acidovorax spp. As with other
naphthalene dioxygenases, substrate specificity is relatively broad and phenanthrene dioxygenases have been implicated in
the biodegradation of naphthalene, phenanthrene, and anthracene and the co-oxidation of larger PAHs. Moreover, at least one
research group has suggested that the PHN group of phenanthrene/naphthalene dioxygenases may be more environmentally
relevant than the classical nah-like naphthalene dioxygenase [9].
Aerobic Biodegradation -n-alkanes:The n-alkanes are a substantial portion of petroleum products and are a component of TPH
concentrations. The QuantArray®-Petro also includes quantification of alkane monooxygenase genes (ALK) which allow a wide
range of Proteobacteria and Actinomycetals to grow on n-alkanes with carbon lengths from C5 to C16 [10]. The QuantArray®-Petro also
includes a second type of alkane hydroxylase (almA) which catalyzes the aerobic biodegradation of longer chain alkanes (C20-C32) by
some Alcanivorax spp. considered dominant in marine systems [11].

Anaerobic Biodegradation - Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX):BTEX compounds are also susceptible to
biodegradation under anoxic and anaerobic conditions although biodegradation pathways for each compound are not as well
characterized as aerobic pathways. The QuantArray®-Petro includes sets of assays targeting a number of upper and lower pathway
functional genes involved in the anaerobic catabolism of BTEX compounds for better evaluation of anaerobic biodegradation at
petroleum contaminated sites.
Benzylsuccinate Synthase (BSS):Of the BTEX compounds, toluene biodegradation under anaerobic conditions is the most
extensively studied and best characterized. The first step in this pathway, mediated by benzylsuccinate synthase (bssA) is the
addition of fumarate onto the toluene methyl group to form benzylsuccinate. While additional pathways are possible, some
bacterial isolates capable of anaerobic biodegradation of ethylbenzene and xylenes follow the same metabolic approach where
the first step is the addition of fumarate.
Anaerobic Benzene Carboxylase (ABC):Although additional pathways are possible, the only pathway for anaerobic
biodegradation of benzene elucidated to date is initiated by a benzene carboxylase enzyme.
Benzoyl Coenzyme A Reductase (BCR):Benzoyl-CoA is the central intermediate in the anaerobic biodegradation of many
aromatic hydrocarbons. Benzoyl-CoA Reductase (BCR) is the essential enzyme for reducing the benzene ring structure.
Anaerobic Biodegradation - PAHs:The anaerobic biodegradation of PAHs involves analogous mechanisms to those described
for anaerobic biodegradation of BTEX compounds. For example, the anaerobic biodegradation of methyl-substituted PAHs like
2-methylnaphthalene is initiated by fumarate addition to the methyl group while the only characterized pathway for anaerobic
naphthalene biodegradation is initiated by a carboxylase.
Naphthylmethylsuccinate Synthase (MNSSA):MNSSA is analogous to the benzylsuccinate synthase described above for
anaerobic biodegradation of toluene. Naphthylmethylsuccinate synthase catalyzes the addition of fumarate onto the methyl
group of 2-methylnaphthalene [12].
Anaerobic Naphthalene Carboxylase (ANC):To date, the only pathway that has been characterized for anaerobic biodegrada-
tion of naphthalene is initiated by a naphthalene carboxylase enzyme [13].
Anaerobic Biodegradation -n-alkanes:As mentioned previously, the n-alkanes are a substantial portion of petroleum products and
should be considered particularly when site cleanup goals include TPH reduction. The addition of fumarate is a common mechanism
for activating and initiating biodegradation of a variety of petroleum hydrocarbons under anaerobic conditions including n-alkanes.
The QuantArray®-Petro includes quantification of alkyl succinate synthase genes (assA) which have been characterized in nitrate
reducing and sulfate reducing isolates utilizing n-alkanes from C6 to at least C18 [14].
