1.0 PROJECT BACKGROUND
1.1 Site Information
The Subject Property is a 1.043 acre tract of land located at 30 Market Street SW in
Concord, Cabarrus County, North Carolina, and it is identified as Cabarrus County tax
parcel 56208775910000. The Subject Property was previously operated as the
headquarters for the Concord Police Department. A Site Location Map is included as
Figure 1.
Mid -Atlantic Associates, Inc. (Mid -Atlantic) understands that the Subject Property is
being evaluated for redevelopment as The Point Apartments. In October 2018, Stewart
Engineering (Stewart) of Charlotte, North Carolina conducted a geotechnical study of
the property. During geotechnical field activities, petroleum odors were reported in
borings B-7 and B-8 from an approximate depth of 12 feet to 27 feet below ground
surface (BGS). It was also reported to Mid -Atlantic that a petroleum underground
storage tank (UST) was also previously located on the Subject Property. A Site Map is
provided as Figure 2.
1.2 Site Investigation
Based on discussions regarding the planned development and review of geotechnical
boring logs provided by Stewart, Mid -Atlantic proposed to evaluate soil and groundwater
at the Subject Property for petroleum impacts. This purpose for conducting further
assessment is based on the following:
• Contaminated soil, if present may impact both the development approach and
cost.
• If soil excavation is conducted during construction at depths below the
groundwater table, impacted groundwater may be encountered in certain areas
of the Subject Property. If dewatering activities are required, the water may need
to be collected and disposed of at a licensed facility if it cannot be directed to the
municipal waste water treatment facility.
• From a regulatory perspective, subsurface impacts below the vadose zone are
regulated as groundwater incidents and will have to be addressed accordingly.
The following text details the field activities and findings of limited assessment activities
conducted at the Subject Property.

Mid -Atlantic was contracted by City of Concord to conduct the limited site assessment
activities. Field work for the project was conducted from December 13 through
December 18, 2018. The soil and groundwater sampling locations are presented on
Figure 3.
2.1 Project Organization
Prior to initiating field work and sampling activities, Mid -Atlantic conducted the following
activities:
• The North Carolina One Call (811) service was contacted on November 26, 2018
to identify and mark subsurface public utilities on the Subject Property.
Subsurface locating was updated on December 11, 2018.
• A site -specific health and safety plan (HASP) was prepared to identify hazards
that may be present during the performance of field work on the property. The
HASP was reviewed with Mid -Atlantic employees and subcontractors prior to
initiating work.
• Mid -Atlantic contracted with Ground Penetrating Radar Systems (GPRS) of
Charlotte, North Carolina to perform subsurface utility locating in the area of each
of the proposed sampling locations. GPRS used electromagnetic (EM) locating
and ground penetrating radar (GPR) to clear the proposed sample locations on
December 13, 2018. Mid -Atlantic personnel were on site with GPRS during the
locating activities.
• Mid -Atlantic contracted with Environmental Drilling and Probing Services (EDPS)
of Charlotte, North Carolina, a North Carolina licensed drilling firm, to perform the
drilling activities associated with this project.
• Mid -Atlantic contracted with Shealy Environmental Services, Inc. (Shealy) of
West Columbia, South Carolina, a North Carolina accredited laboratory, to
perform analytical testing for this project.

2.2 Soil Investigation
Nine soil borings (SB-1 thru SB-5, TW-1 thru TW-4) were advanced at the Subject
Property on December 13, 2018. The soil borings were advanced using a combination
of direct push technology (DPT) and hollow stem augurs (HSA) by EDPS. Soil boring
installation information is as follows:
• Soil boring SB-1 was advanced to refusal at a depth of approximately 15 feet
BGS using DPT. Soil obtained from the boring was field screened in two -foot
intervals with a photoionization detector (PID). Based on field screening results
and observed soil conditions, a soil sample was selected from the 8 to 10 foot
interval for laboratory analysis for volatile organic compounds (VOCs) by EPA
Method 8260. Soil samples were also collected for possible analysis for semi -
volatile compounds (SVOCs) by EPA Method 8270 and for petroleum
hydrocarbon fractions by Massachusetts Department of Environmental Protection
Volatile Petroleum Hydrocarbons/Extractable Petroleum Hydrocarbons (MADEP
VPH/EPH).
• Soil boring SB-2 was advanced to refusal at a depth of approximately 9 feet BGS
using DPT. Based on the PID field screening results and observed soil
conditions, a soil sample was selected from the 7 to 9 foot interval for analysis for
VOCs by EPA Method 8260. Soil samples were also collected for possible
analysis for SVOCs by EPA Method 8270 and by MADEP VPH/EPH.
• Soil boring SB-3 was advanced to refusal at a depth of approximately 10 feet
BGS, using DPT. Field screening with a PID did not indicate the presence of
elevated levels of VOCs, and a soil sample was not collected from boring SB-3.
• Soil boring SB-4 was advanced to a depth of approximately 22 feet BGS using
DPT. Based on field screening and observed soil conditions a sample was
selected from the 6 to 8 foot interval for analysis for VOCs by EPA Method 8260.
Soil samples were also collected for possible analysis for SVOCs by EPA
Method 8270 and by MADEP VPH/EPH.

• Soil boring SB-5 was advanced to a depth of approximately 22 feet BGS using
DPT. Field screening with a PID did not indicate the presence of elevated levels
of VOCs, and a soil sample was not collected from boring SB-5.
• Soil boring TW-1 was advanced to a depth of approximately 22 feet BGS using
DPT and HSA. Field screening was not conducted on soil from TW-1 due to
poor recovery, and a soil sample was not collected.
• Soil boring TW-2 was advanced to a depth of approximately 20 feet BGS using
DPT and HSA. Based on PID field screening results and observed soil
conditions, a soil sample was selected from the 6 to 8 foot interval for analysis for
VOCs by EPA Method 8260. Soil samples were also collected for possible
analysis for SVOCs by EPA Method 8270 and by MADEP VPH/EPH.
• Soil boring TW-3 was advanced to a depth of approximately 20 feet BGS using
DPT and HSA. Based on field observations and strong petroleum odors, a soil
sample was selected from the 17 to 20 foot interval for analysis for VOCs by EPA
Method 8260. Soil samples were also collected for possible analysis for SVOCs
by EPA Method 8270 and by MADEP VPH/EPH.
• Soil boring TW-4 was advanced to a depth of approximately 22 feet BGS using
DPT. Based on field screening and observed soil conditions a sample was
selected from the 8 to 10 foot interval for analysis for VOCs by EPA Method
8260. Soil samples were also collected for possible analysis for SVOCs by EPA
Method 8270 and by MADEP VPH/EPH.
Soil sample locations are indicated on Figure 3. Soil samples were collected in
accordance with the Mid -Atlantic Field Procedures which are provided in Appendix A.
Copies of the Boring Logs for the soil samples are included in Appendix B.
Upon completion of soil sampling activities, EDPS backfilled the soil borings with
bentonite pellets. Soil cuttings obtained from the soil boring activities were
containerized in a drum for storage prior to disposal. The Geoprobe tooling was
decontaminated between sampling locations using liquinox and water.

After collection, the soil samples were preserved in an ice -filled cooler. The EPA
Method 8260 soil samples were submitted to Shealy for chemical testing under chain -
of -custody control. The EPA Method 8270 and MADEP VPH/EPH samples were
submitted under "Hold" status pending the VOC analytical results for the soil samples.
2.3 Groundwater Investigation
Temporary Well installation
Four temporary groundwater monitoring wells (TW-1, TW-2, TW-3 and TW-4) were
installed at the Subject Property by EDPS on December 13 and 14, 2018. The
temporary wells were installed using hollow stem augers. The borings were logged, and
soil was screened in two -foot intervals with a PID for possible impacts. The temporary
monitoring wells were installed as follows:
• Temporary well TW-1 was installed in the western corner of the site on
December 14, 2018. The two-inch diameter PVC well was set to approximately
20 feet with a 10-foot section of 0.010-inch mill slotted screen and a 10-foot solid
riser.
• Temporary well TW-2 was installed to the southeast of the former gasoline UST
pit on the Subject Property. The temporary well was constructed on December
14, 2018. The two-inch diameter PVC well was set to approximately 20 feet with
a 10-foot section of 0.010-inch mill slotted screen and a 10-foot solid riser.
• Temporary well TW-3 was installed in the southern portion of the Subject
Property in the general area of historical geotechnical boring B-8 on December
13, 2018. The two-inch diameter PVC well was set to approximately 18.5 feet
with a 10-foot section of 0.010-inch mill slotted screen and an 8.5-foot solid riser.
• Temporary well TW-4 was installed on the southern corner of the property on
December 13, 2018. The two-inch diameter PVC well was set to approximately
18.5 feet with a 10-foot section of 0.010-inch mill slotted screen and an 8.5-foot
solid riser.

After installation of the well casing, a sand pack was installed in each boring by EDPS
from the base of the well to approximately two feet above the top of the screen. An
approximate two foot thickness of bentonite was installed on top of the sand. Water
was added to the bentonite pellets, and it was allowed sufficient time to hydrate prior to
well development. The soil cuttings from the drilling activities were collected and
containerized in labeled 55-gallon drums for disposal.
During soil sampling activities, one existing permanent groundwater monitoring well
(MW-2) was observed in the parking lot to the north of the former UST pit. Well
construction information is provided in Table 1. The monitoring well locations are
indicated on Figure 3. Copies of the Boring Logs prepared for the temporary wells are
provided in Appendix B.
Well Sampling
Mid -Atlantic conducted groundwater sampling activities on the Subject Property on
December 17, 2018. Mid -Atlantic gauged, purged and sampled the four temporary
monitoring wells (TW-1 thru TW-4) and the existing permanent well (MW-2).
Groundwater samples were collected as follows:
• Prior to sampling, each well was developed and purged a minimum of three well
volumes or until dry using a dedicated PVC bailer. Development water and purge
water were collected and containerized in labeled 55-gallon drums for storage
prior to disposal.
• After allowing sufficient time for recharge, groundwater samples were collected
from temporary wells TW-1, TW-2, TW-3, and TW-4 for analysis for VOCs by
EPA Method 8260 and for polycyclic aromatic hydrocarbons (PAHs) by EPA
Method 8270. Samples were collected from monitor well MW-2 for analysis for
VOCs by EPA Method 8260 and SVOCs by EPA Method 8270, and for possible
analysis of petroleum hydrocarbon fractions by MADEP VPH/EPH. Each
groundwater sample was collected using a dedicated PVC bailer. New nitrile
gloves were worn during the collection of each sample.

After collection, the groundwater samples were preserved in an ice -filled cooler. The
groundwater samples were submitted to Shealy for chemical testing under chain -of -
custody control. The MADEP VPH/EPH samples were submitted under "Hold" status
pending the VOC analytical results for MW-2.
Groundwater Flow Direction
After sampling on December 17, 2018, the top -of -casing elevations for the four
temporary wells and the permanent well were surveyed. The depth to groundwater
measurements in each well were recorded on December 18, 2018. Top -of -casing
information and depth to water data is provided in Table 1.
Based on information obtained during field work at the Subject Property, the
groundwater flow direction is generally to the west. The estimated groundwater flow
direction is presented on Figure 4.
Additional Field Activities
The following additional activities were conducted during the field work portion of this
assessment:
• On December 18, 2018 EDPS abandoned the four temporary monitoring wells
that had been installed at the Subject Property. The temporary wells were
abandoned by removing the well materials, if possible, and plugging the borings
using bentonite chips. The surfaces of temporary well locations within the
parking lot were sealed with asphalt patch. Mid -Atlantic personnel were on -site
to oversee well abandonment activities.
• The drums of soil cuttings and water generated during this assessment were
secured and labeled. The drums are stored adjacent to a wall on the west side
of the Subject Property. Mid -Atlantic understands that the drums will be
disposed of once waste characterization has been completed.

Copies of the laboratory analytical reports and chain -of -custody records for the samples
collected at the site by Mid -Atlantic are provided in Appendix C. The analytical results are
summarized on Table 2 and Table 3.
3.1 Soil Analytical Results
Analytical testing of soil sample TW-3 by EPA Method 8260 indicated the presence of
Benzene at 13 micrograms per kilogram (ug/kg), which exceeds its applicable North
Carolina Maximum Soil Contaminant Concentration — Soil to Groundwater (NCMSCC-
STG) standard. In addition, Cyclohexane and Methylcyclohexane were reported at
concentrations above laboratory minimum detection limits in sample TW-3, and neither
compound has an NCMSCC standard for Residential, Industrial/Commercial or Soil to
Groundwater. No other EPA Method 8260 target compounds were reported in analysis
of samples SB-1, SB-2, SB-4, TW-1, TW-3 and TW-4 at concentrations in excess of
their respective NCMSCC Residential, Industrial/Commercial or Soil to Groundwater
standards. The soil analytical results are summarized in Table 2.
Based on the reported EPA Method 8260 analytical results, it was determined during a
conversation with Mr. Blat and Mid -Atlantic that other soil samples collected during field
activities would not need to be analyzed. Shealy was contacted and the EPA Method
8270 and MADEP VPH/EPH "Hold" samples were not tested. The samples were
disposed of by the laboratory.
3.2 Groundwater Analytical Results
Analytical testing of groundwater sample TW-3 by EPA Method 8260 indicated the
presence of 1-Methyl naphthalene, Benzene, Isopropyl benzene, Methylene Chloride and
Naphthalene at concentrations in excess of their respective North Carolina Groundwater
Quality Standards (NCGQS). In addition, Cyclohexane and Methylcyclohexane were
reported at concentrations above laboratory minimum detection limits in sample TW-3,
and neither compound has a specific NCGQS. No other EPA Method 8260 target
compounds were reported for samples TW-1, TW-2, TW-3, TW-4 and MW-2 at
concentrations in excess of their respective NCGQS standards.

Analytical testing of groundwater samples TW-1, TW-2, TW-3, TW-4 and MW-2 by EPA
Method 8270 did not indicate concentrations of target compounds in excess of their
corresponding laboratory minimum detection limits.
The groundwater analytical results are summarized in Table 3.
Based on the reported EPA Method 8260 and 8270 analytical results for sample MW-2,
it was determined during a conversation with Mr. Blat and Mid -Atlantic that the MADEP
VPH/EPH "Hold" groundwater samples at MW-2 would not be needed. Shealy was
contacted and the MADEP VPH/EPH "Hold" samples were not tested. The samples
were disposed of by the laboratory.
4.0 SUMMARY AND RECOMMENDATIONS
4.1 Project Summary
Mid -Atlantic performed the following work during December 2018 to investigate the
subsurface in selected areas at the Subject Property:
• Nine soil borings (SB-1 thru SB-5, TW-1 thru TW-4) were advanced at the
Subject Property. Based on field screening results and field observations, soil
samples were collected from borings SB-1, SB-2, SB-4, TW-1, TW-3 and TW-4
for analysis for VOCs by EPA Method 8260.
• Analytical testing of soil sample TW-3 by EPA Method 8260 collected from a
depth of 17 to 20 feet BGS indicated the presence of Benzene at a concentration
exceeding its NCMSCC-STG standard. In addition, Cyclohexane and
Methylcyclohexane were reported at concentrations above laboratory minimum
detection limits in sample TW-3, and neither compound has established North
Carolina soil standards. Subsequently, soil sample TW-3 was determined to be
below the vadose zone and is indicative of groundwater quality conditions as
described below. No other EPA Method 8260 target compounds were reported in
analysis of samples SB-1, SB-2, SB-4, TW-1, TW-3 and TW-4 at concentrations
in excess of their respective North Carolina soil standards.

• Four temporary groundwater monitoring wells (TW-1 thru TW-4) were installed at
the subject site. One existing permanent groundwater monitoring well (MW-2)
was observed during field activities. Groundwater samples were collected from
MW-1 for analysis for VOCs by EPA Method 8260 and for SVOCs by EPA
Method 8270. Groundwater samples were collected from TW-1 thru TW-4 for
analysis for VOCs by EPA Method 8260 and for PAHs by EPA Method 8270.
• Analytical testing of the groundwater sample TW-3 indicated by EPA Method
8260 indicated the presence of 1-Methyl naphthalene, Benzene,
Isopropylbenzene, Methylene Chloride and Naphthalene at concentrations in
excess of their respective NCGQS. In addition, Cyclohexane and
Methylcyclohexane were reported at concentrations above laboratory minimum
detection limits in sample TW-3, and neither compound has a specific NCGQS.
No other EPA Method 8260 target compounds were reported in analysis of
groundwater samples TW-1, TW-2, TW-3, TW-4 and MW-2 at concentrations in
excess of their respective NCGQS standards.
• The groundwater flow direction at the Subject Property at the time of this limited
assessment was generally to the west.
• The soil borings and temporary monitor well locations were abandoned by EDPS
upon completion of the project.
• Drums of soil cuttings and water generated during the field activities were stored
adjacent to a wall on the west side of the Subject Property.
4.2 Project Findings and Recommendations
The following findings were identified during the work of this investigation:
• Petroleum -affected soils were not encountered above the groundwater table at the
Subject Property during the site investigation.
• Petroleum -impacted groundwater was identified on the southwestern portion of the
Subject Property.

Given the nature of the planned development, minor soil contamination and lack of
anticipated future groundwater use at the Subject Property the following recommendations
are provided based on the findings of this investigation:
• While no significant soil contamination was identified, observation of soil conditions
during any excavation should be conducted. If visual staining or odors are
identified, field screening of the potentially affected soil should be conducted, along
with additional soil sampling and analysis if field screening so indicates. Mid -
Atlantic's assessment activities were limited in nature, and while conducted in areas
believed to represent worst -case scenario conditions, may not be indicative of soil
conditions in areas not sampled or investigated. This risk is believed to be low.
• Mid -Atlantic understands that the area investigated is planned for apartment
construction with a below grade parking structure. Should this construction extend
below the groundwater table, dewatering may be required. If this is the case, Mid -
Atlantic recommends procurement of permission from the City of Concord to
discharge the groundwater generated to the local publicly owned treatment works
via a permit or other mechanism as dictated by City requirements.
• During excavation, should subsurface conditions differ significantly from those
observed by Mid -Atlantic, a Vapor Intrusion Mitigation System (VIMS) may be
considered as part of the design of any new structures to address any vapors that
may collect in or beneath planned structures. The evaluation of alternatives for
mitigating existing structures can include an active or passive VIMS, HVAC
manipulation and/or exhaust fans as appropriate commensurate with the final
design and the evaluation of potential risk. Construction of a below grade parking
structure, along with adequate ventilation should mitigate any potential vapor risks.
Based on our evaluation of data collected during our investigation, no known vapor
intrusion condition exists based on contaminants and concentrations identified.

Soil Sampling Procedures
Sample Collection
Direct Push Technology (DPT, or "Geoprobe")
DPT uses a truck -mounted hydraulic rig to push a steel sampling probe into the
subsurface to collect soil and/or groundwater samples. The sampling device used to
collect the soil samples during this investigation was the "macrocore" sampler. This
sampler consists of a four -foot long, two-inch diameter stainless steel spoon containing a
clear, acetate liner. When the macrocore sampler is driven into the subsurface, the soil is
collected into the acetate liner and then retrieved to the land surface. The liner is then cut
open and the soil lithology is characterized and soil samples are collected.
Split Spoon Sampling
This method of soil sampling is typically used during advancement of hollowstem augers
for the construction of monitoring wells. Soil samples are obtained from the borings by
driving a prewashed, 1-3/8-inch inner -diameter split -spoon sampler at five foot intervals to
termination in general accordance with ASTM D-1586 (Standard Penetration Test)
specifications. Blow counts for each six inches of split -spoon penetration are recorded
during advancement of the spoon. Samples are then retrieved to the land surface, the
split -spoon is opened, and the soil lithology is characterized and soil samples are
collected.
Hand Augering
This method is typically used for shallow sampling in areas where access is limited or
underground obstacles such as utilities may be present. A pre -washed, three-inch
diameter steel auger bucket is attached to extension rods and manually turned to
penetrate the subsurface to the desired sampling depth. Samples are then retrieved to the
land surface and the soil lithology is characterized and soil samples are collected directly
from the hand auger bucket.
Excavator Bucket Sampling
This method is typically used during UST excavation and soil excavation projects. The soil
samples are collected from the excavator bucket when it is not safe to collect the samples
by other means. Care is taken when collecting samples from the bucket to avoid soil that
has come in contact with the bucket itself to avoid cross contamination.

II. Headspace Field Screening
A portion of each sample is removed from the sampling device and placed in a pre -
labeled, plastic "ziploc" bag. After several minutes, the gas contained in the "headspace"
or void area within the bag is tested with a photoionization detection (PID) and/or Flame
Ionization Detector (FID). These are useful as scanning devices to detect the presence of
volatile organic compounds (VOCs) but are not relied upon to determine specific levels of
contamination. Typically, the samples exhibiting the highest headspace readings will be
submitted to the laboratory for analysis.
III. Preparation for Laboratory Analysis
The sample collector dons new nitrile sampling gloves prior to handling each sample. The
samples are placed into laboratory -prepared, pre -labeled, sampling containers, packed in
ice, and shipped to a certified laboratory under chain -of -custody control. The sampler
places an executed custody seal on the cooler prior to leaving the sampler's custody.
Laboratory analyses to be performed on the samples, along with other sampling
information, are specified on the chain -of -custody, which is placed in the cooler with the
samples.

Monitoring Well Installation Procedures
Shallow Type II Monitoring Wells
These wells are typically constructed in a borehole made by a power auger and penetrate
the top portion of the shallow water table. The wells are typically constructed of two-inch
diameter (although they can be larger), Schedule 40 PVC casing with 0.010-inch
mechanically slotted well screen placed in the bottom of the well. These wells are
constructed such that the well screen intersects the water table at the time of
construction. A gravel pack (typically clean washed sand) is used to fill the borehole
annular space around the screened interval and is usually terminated one to two feet
above the top of the screen. A typically two -foot thick layer of bentonite is then placed in
the annular space above the sand pack, and the remainder of the annular space is filled
from bottom to top with a Portland cement/bentonite mixture pumped through a tremie
pipe. The monitoring wells are equipped with locking caps and fitted with flush -mounted
protective manhole covers or above -ground "stick-up" protectors.
Note: for site -specific well construction details, refer to Well Construction Records
II. Deep Type III Monitoring Wells
Deep, Type III monitoring wells are constructed with two "telescoping" casings, an inner
casing and an outer casing. The outer casing is larger in diameter (typically six-inch
diameter Schedule 40 PVC) and typically extends from land surface to bedrock or a
confining unit. The bottom of this casing is typically firmly set into the top of bedrock or
other confining layer and then tremie-grouted into the borehole. After the grout has
cured, the borehole is then advanced below the bottom of the outer casing by drilling
through the outer casing to the desired depth. The inner casing (typically two-inch
diameter Schedule 40 PVC) is constructed with a screened interval that monitors water
within bedrock fractures or other deeper water -bearing zones. The borehole annulus is
then filled with gravel pack, bentonite, and grout and finished at land surface as
described above.
Note: for site -specific well construction details, refer to Well Construction Records

Groundwater Sampling Procedures
Sample Collection
A. Monitoring Wells
Prior to sample collection, each well is purged of three to five standing well volumes or to
dryness to remove stagnant water from the well and well bore in an effort to collect
samples that are representative of the water quality in the formation surrounding each
well. Purging is performed either with a new, polyethylene bailer dedicated to each well, or
with a decontaminated pump. Samples are retrieved from the monitoring well using the
dedicated bailer. New nylon string is used on each dedicated bailer, and new nitrile
sampling gloves are donned prior to purging and sampling of each well.
B. Geoprobe "Screen Point Sampler"
The screen point sampler is a "grab" sampling device that is driven into the saturated zone
and a surrounding metal sheath is retracted, exposing a screen. Groundwater entering the
screen is then drawn to land surface through disposable tubing that is placed through the
hollow push rods. The sample is collected from the tubing into the appropriate sampling
glassware.
C. Water -Supply Wells
Water samples are typically collected from the available spigot that is nearest to the well.
The water is allowed to run at a high flow from the spigot for approximately 10 to 15
minutes to allow the water in the delivery lines to be purged. The sample flow is then
reduced and the samples are collected directly into pre -labeled containers as described
below. New nitrile sampling gloves are donned prior to sampling of each well.
D. Treatment System Influent/Effluent
Samples are typically collected from the influent or effluent of pump -and -treat groundwater
remediation systems using designated sampling ports in the influent and effluent water
transport lines. The water is typically allowed to run for several seconds to clear potential
debris in the sampling port. The sample is then collected directly into sampling containers
as described below. New nitrile sampling gloves are donned prior to sample collection.
II. Preparation for Laboratory Analysis
Groundwater samples are decanted directly into laboratory -prepared, pre -labeled, sampling
containers, packed in ice, and shipped to a certified laboratory under chain -of -custody control.
Laboratory analyses performed on the samples are specified on the chain -of -custody.

Volatiles
The matrix spike (MS) associated with sample -003 had methyl acetate recovered outside of the
acceptance limits. Additionally, the RPD exceeded the acceptance limit. The laboratory control sample
(LCS) was recovered within the required acceptance limits; therefore, this likely demonstrates a matrix
effect.
