EXECUTIVE SUMMARY

Terraquest Environmental Consultants, P.C. has performed a groundwater sampling event for the
Barker’s Grocery 2 petroleum UST release incident. The site is in Statesville, Iredell County, North
Carolina and the work was performed for the responsible party, Beroth Oil Company.

Recent assessment activities have confirmed the absence of GCL violations in the five sampled
wells at the site. With the reported groundwater flow direction and lack of GCL violations,
Terraquest recommends taking steps toward closure for this release incident. The Risk Ranking
should be lowered.

1.0 INTRODUCTION

On behalf of the responsible party, Beroth Oil Company, Inc., Terraquest Environmental
Consultants, P.C. performed a groundwater sampling event in December 2022 for the Barkers
Grocery-2 release incident. The site is located in Statesville, Iredell County, North Carolina. The
work concerns the release incident discovered during the 12/2020 UST closure, Incident 47627.
A previous release incident (8489) was opened and closed at this site. Activities in this report
were pre-approved on ePATA 8489/47627-038.

Note that this is the second groundwater sampling event since the April 4-8, 2022 Mobile Multi-
Phase Extraction (MMPE) performed to reduce GCL violations as a measure of lowering risk to a
lateral water supply well.

The site location, vicinity, and layout are depicted in Figures 1, 2, and 3, respectively. Terraquest’s
technical methods and standard procedures are detailed in Appendix A.

2.0 SITE HISTORY AND CHARACTERIZATION

Beroth Oil Company is the owner of two generations of tanks at this site. As shown in Table 1,
the first set of tanks included 1, 2,000-gallon diesel, 1, 560-gallon kerosene, 1, 1,000-gallon
gasoline, 1, 1,056-gallon gasoline, and one 2,000-gallon kerosene. The second generation of
tanks included 1, 4,000-gallon diesel, 1, 2,000-gallon kerosene, and 3, 8,000-gallon gasoline. The
first generation of tanks were closed in 1990 and the second in 2020. Further tank details are
provided in Table 1.

The site is located on Hwy 21 in a rural area north of Statesville, NC. Land use surrounding the
facility is chiefly residential with some businesses located along Turnersburg Highway. All
properties within 1,500 feet of the site are zoned R-20 (residential) according to the Iredell
County website. Surrounding property owner information is provided in Table 2.

Monitoring Report (12/1/22) Beroth Oil Company, Inc. Prepared by: Terraquest Environmental Consultants, P.C. (#47627) Barker’s Grocery-2
Report Prepared: December 13, 2022 2 Statesville, NC

A prior release incident (#8489) identified soil contamination but no groundwater contamination
in excess of applicable limits. A Soil Vapor Extraction (SVE) remedial system was installed in April
2012 and was active until its shut down in December 2016. Following public notice, the NCWM-
UST issued a No Further Action Letter for the #8489 release incident.

As part of closure activities in December 2020, Terraquest personnel collected samples around
the UST basin and at prescribed locations near product lines and dispensers. The large amount
of pea gravel in the UST basin prevented the collection of soil samples directly beneath the tanks
and a groundwater monitoring well was installed instead. The analytical results of a groundwater
sample collected from that well (MW1), revealed the presence of petroleum-type contaminants
at concentrations exceeding the 2L Standards. The UST Closure Report (UST-12) (January 29,
2021) previously submitted to the NCDWM-UST detailed these activities. Following review of the
UST Closure Report, the NCDWM-UST’s March 19, 2021 Acknowledgement of Report Receipt
correspondence agreed with the conclusions to move forward with risk-ranking activities similar
to an LSA.

Prior work associated with the closed release incident 8489, identified two sole-source potable
wells within a 1,500-foot radius of the site. One of these wells is located within 1,000 feet of the
source area. A production well operated by Iredell County was found at a distance of 1,570 feet
from the source area. This well provides municipal water for the entire surrounding community
not using their own potable wells. Two non-potable use wells were also identified within 1,500
feet of the site. The well locations are shown on Figure 2 and detailed on Table 3.

These wells were confirmed through July 7, 2021 reconnaissance efforts. Terraquest inquired
with the property owner of the potable well located within 1,000 feet of the release area if he
would be interested in connecting to the municipal water supply system. The bare-chested man

Report Prepared: December 13, 2022 3 Statesville, NC
quickly closed the door while stating that he was “not interested”. The release incident remains
a High Risk based on this sole-source well use.

As part of the reconnaissance effort, Terraquest also searched for any surface water bodies
within a 500-foot radius of the site. A dried pond basin was noted to the west of the site in the
location shown on Figure 2. The USGS Statesville East and Statesville West quadrangle maps of
the area show the presence of Fifth Creek located to the north. The Iredell County GIS website
shows un-named tributaries to Fifth Creek in the locations shown on Figure 2. The dried pond
observed by Terraquest was confirmed by this website as located to the west of the site.

The site is located in the Piedmont Physiographic Province of North Carolina. The Piedmont is
characterized by a hummocky terrain with variable topographic relief. The site lies within the
Inner Piedmont Lithotectonic Province of North Carolina, a subdivision of the Appalachian
Piedmont Province. The Inner Piedmont Belt primarily consists of metamorphosed sedimentary
and volcanic rocks of upper Proterozoic to lower Cambrian age. Specifically, the lithology noted
for the site on the Geologic Map of North Carolina consists of gneiss’s and schists that are
inequigranular, have locally abundant potassic feldspar and garnet, are interlayered and
gradational with calc-silicate rock, and sillimanite-mica shist, mica schist, and amphibolite may
be present (Brown, et al., 1985). The lithology has been mapped by Goldsmith, et al. (1988) as
upper Proterozoic - Cambrian biotite gneiss. This unit is composed of thin to thick layered biotite-
quartz-feldspar gneiss with local layers of mica schist. The encountered lithology at the site was
a silt (ML) from the surface to a depth of 45 feet below ground level (BGL). The silt was logged
as soft, brown/dark brown/orange/maroon/tan, with varying amounts of mica.

3.0 SOIL QUALITY ASSESSMENT

During the December 2020 UST closure, Soil samples were collected every ten feet along the
product lines and beneath each of the four dispensers. The product line samples were collected
5 feet BGL and the dispenser samples at 3 feet BGL. The tanks were bed in such a large volume

Report Prepared: December 13, 2022 4 Statesville, NC
of pea gravel that native soil was not encountered by the excavator performing removal. The
prior removal of tanks was likely the reason that so much pea gravel was present during the
current work. Without removing all of the pea gravel, which fills in each scoop removed, it was
not possible to reasonably reach native soil. Additional support via shoring was required to
prevent undermining of the excavated area and possible structural damage to the onsite building
and was outside the scope of this project.

The dispenser and product line samples were collected from the track-hoe bucket and
groundwater samples from a new, disposable bailer. All samples were collected by Terraquest
personnel donning new disposable nitrile gloves. Samples were then placed into laboratory
containers, preserved with acid as required and packed on ice pending onsite lab analysis. Chain-
of-custody documentation was maintained for each sample. All UST closure soil samples were
analyzed utilizing UVF technology targeting TPH GRO and DRO. Those results reported no TPH
Action Level exceedances in any sample. Sample IDs, depths, dates, and analytical results are
listed in Table 4 and the locations are provided on Figure 4.

As part of additional risk assessment activities, Terraquest personnel supervised the collection of
soil samples as close to the bottom of the tank basin as possible on July 7, 2021. Following utility
location by a private locator, a soil boring, B1, was advanced at the location shown on Figure 4.
A sample could not be collected from directly beneath the UST basin as it was filled with pea
gravel to an unknown depth. The boring location was away from septic lines and other utilities
in the area. A NC-licensed driller advanced the boring using a Geoprobe 7822 drilling unit. Soil
samples were collected from beneath the location of the former USTs in intervals until the water
table was reached. The exact intervals were from 20-23 feet BGL and from 30-33 feet BGL. An
additional sample was collected within the water table from 37-40 feet BGL. The samples were
placed into the appropriate laboratory-supplied containers, labeled, packed on ice, and
transported to an NC-certified lab for analysis per 8260 and MADEP VPH.

Report Prepared: December 13, 2022 5 Statesville, NC
The analytical results reveal the presence of petroleum-type contaminants, however, neither of
the vadose zone soil samples, 20-23’ and 30-33’, had reported concentrations in excess of the
soil-to-groundwater maximum soil contaminant concentrations (STG MSCCs). The analytical
results are summarized in Table 5.

4.0 GROUNDWATER QUALITY ASSESSMENT

Prior to purging and sampling the monitoring well network on December 1, 2022, Terraquest
personnel first measured the depth-to-water in each well. Those measurements were used in
conjunction with surveyed top of casing elevations to determine the direction of groundwater
flow. Figure 5 was generated to show the potentiometric surface which is decreasing to the
east/northeast. Groundwater elevation data is summarized in Table 6. Historical groundwater
data is shown in Appendix B that reveals that, on average, the water table has dropped by over
four feet since last measured in June 2022.

On December 1, 2022, Terraquest personnel collected groundwater samples from monitoring
wells TQMW1-TQMW5. Prior to sampling, each well was purged of at least three well volumes
of water using a new disposable bailer. Bailers were then used to retrieve a representative
groundwater sample from each well. Upon retrieval, the samples were placed into the
appropriate laboratory-prepared sample containers, labeled, and packed on ice pending
shipment to a North Carolina-certified laboratory for analysis. All the collected groundwater
samples were submitted for analysis per 6200B for VOC’s.

The groundwater results from the December 1, 2022 sampling event reveal no GCL violations.
Note that the April 2022 MMPE event was previously performed with that goal in mind and was
backed up with the June 2022 and now December 2022 data showing a stable plume. While 2L
Standard violations remain, they are below the GCLs and are located in an upgradient and lateral
direction from the sole active water supply well ranking this site a High Risk.

Monitoring Report (12/1/22) Beroth Oil Company, Inc. Prepared by: Terraquest Environmental Consultants, P.C. (#47627) Barker’s Grocery-2
Report Prepared: December 13, 2022 6 Statesville, NC
Groundwater analytical results are summarized on Figure 6 and detailed on Table 7. Historical
groundwater data is shown in Appendix B. The full analytical report is provided in Appendix C.

There is no GCL plume reported. The 2L Standard violation plume covers an area of 6,600 square
feet. That is a reduction from the 8,700 square feet reported for the previous October 2021
sampling event and is the same size and shape as the June 2022 plume. The plume is stable with
many contaminants reducing in concentration.

5.0 CONCLUSIONS

Recent assessment activities have confirmed the absence of GCL violations in the five sampled
wells at the site. With the reported groundwater flow direction and lack of GCL violations, As
this is the second event confirming the absence of GCL violations and stability of the plume,
Terraquest recommends moving this release incident toward closure.

6.0 LIMITATIONS

This report is limited to the investigation of petroleum hydrocarbons only and does not imply
that other unforeseen adverse impacts to the environment are not present at the facility. In
addition, subsurface heterogeneities not identified during the current study may influence the
migration of groundwater or contaminants in unpredicted ways. The limited amount of sampling
and testing conducted during this study cannot practically reveal all subsurface heterogeneities.
Furthermore, the subsurface conditions, particularly groundwater flow, elevation, and water
quality may very through time. The opinions and conclusions arrived at in this report are in
accordance with industry-accepted geologic and hydrogeologic practices at this time and
location. No warranty is implied or intended.

 TECHNICAL METHODS/STANDARD PROCEDURES 

Equipment Decontamination 

All soil sampling equipment utilized during site assessment activities is decontaminated according 
to standard and accepted protocol.  Cleaning solutions range from clean potable water to acidic 
solutions or organic solvents depending on the contaminants present at the site.  Equipment 
utilized at sites, such as hand augers, contaminated with petroleum hydrocarbons, is generally 
decontaminated with a low‐sudsing detergent such as Luiquinox® and triple rinsed with distilled 
water.   Larger equipment, such as drill rigs and associated tools, is steam cleaned.   All 
decontamination procedures are completed within an established decontamination area which is 
located away from the active study area.  Frequency of equipment decontamination depends on 
the nature of work being performed, but in no case is decontamination performed less frequently 
than once per test (i.e., soil boring, well installation, sample collection, etc.).  Equipment blanks are 
collected as a quality control measure when required by job specifications. 

Soil Boring Installation 

Soil borings are completed using hand‐operated sampling tools, truck‐mounted drills, or 
Geoprobe® drilling rigs depending on the depth of sample collection and other site‐specific 
conditions.  Hand operated stainless‐steel bucket augers are utilized to collect soil samples at 
regular intervals to determine site stratigraphy and to test for the presence of volatile organic 
compounds.  Samples retrieved from the hand auger are necessarily disturbed during the augering 
process, but can provide accurate information on soil type and contaminant concentrations when 
properly interpreted.  Soil samples from hand augered borings are generally retrieved at one to 
two foot intervals. 

Truck‐mounted or Geoprobe® drilling equipment is often utilized when sample retrieval depths 
exceed twenty feet or subsurface conditions prevent utilization of hand augers (i.e., buried rocks, 
wood, bricks or other materials occur in the subsurface).  Truck‐mounted drilling rigs usually 
retrieve soil via a hollow‐stem auger/split spoon collection method.  Geoprobe® rigs usually employ 
a Macro‐Core® tube retrieval system.   

Hollow stem augers provide relatively undisturbed 2‐foot cores of soil samples.  Soil samples are 
generally collected at five foot intervals utilizing standard penetration test procedures as defined 
by the American Society for Testing and Materials (ASTM) or are pushed to the desired depth using 
the head of the drill rig.  The standard penetration test involves driving a 2" outside diameter by 1‐
3/8" inside diameter split‐spoon sampler a minimum distance of one foot with a 340‐lb. slide 
hammer falling a distance of 30 inches.   

A Geoprobe® rig is a hydraulically‐powered soil probing machine.  The probe utilizes static force 
and percussion to advance a small diameter sampling device into the subsurface.  The sampling 
apparatus provides relatively undisturbed 5‐foot cores of soil samples.  Soil samples are collected 
Page 2 of 8 
continuously.  The Macro‐Core® tube contains an inserted poly‐vinyl chloride (PVC) liner which 
retains the soil sample as the tube is driven into the ground.   The Macro‐Core® tube is 
decontaminated between each 5‐foot sample interval in a soil boring using a Liquinox and tap‐
water mixture.  A new PVC liner is used to collect soil from each sample interval in a soil boring.    

Soil samples retrieved from the hollow‐stem augers or Geoprobe are then carefully described 
according to the Unified Soil Classification System.  Soil descriptions are recorded on a soil 
boring log. 

Soil Sampling 

Soils to be analyzed by a North Carolina‐certified laboratory are prepared according to the specified 
analytical method.  Initially, soil samples are removed from the ground using either a hand auger, 
backhoe bucket, spilt spoon auger, or a Macro‐Core® sampling tube.  During the removal, care is 
taken to keep the disturbance of the soil structure to a minimum to reduce the loss of 
contaminants.  Once removed, the samples are placed in the proper sample container for the 
specified analytical method.  For samples collected for the MADEP VPH and EPA Method 8260, a 
TerraCore® sampler is used to collect one 5‐gram allotment of soil.  The allotment is placed in 
methanol‐preserved 40 mL vials.  Also, one 5‐gram allotment of soil is placed into sodium bisulfate‐
preserved 40 mL vials (one 5‐gram allotment per vial, 2 vials per sample) for the 8260 low 
concentration method.  A 250‐mL glass jar of the sampled soil is also collected to provide moisture 
content information.  Soils sampled for MADEP EPH, EPA Method 8270 and TPH 5030 and 3550 are 
placed in a 250‐mL glass jar (for MADEP EPH analysis an amber jar is required).  TPH 5030 samples 
are preserved in methanol similar to the 8260 analysis.  Field personnel wear new, disposable 
nitrile gloves during the collection of each sample.  

The soil samples are labeled with the sample location, sample identification, date and time of 
collection, and the analytical method.  The samples are placed on ice, sent to a laboratory, and 
analyzed before the expiration of an analytical method’s prescribed holding time.  Chain‐of‐custody 
documentation is maintained for each sample collected in the field. 

If the soil is being sampled for volatile or semi‐volatile compounds, a portion of the collected soil is 
placed in a sealable bag and screened for volatile organic vapors.  Head screening procedures are 
described in the following paragraph.  

Headspace Screening 

Collected soil samples are routinely tested for the presence of volatile organic compounds (VOCs).  
After retrieval from the ground, a portion of a soil sample is placed in a sealable plastic bag.  The 
soil samples are then set aside for approximately five minutes so that volatile constituents present 
in the sample can reach equilibrium concentrations with headspace gases in the bag.  Once a 
suitable time period has passed, the probe of the sampling instrument, typically an Organic Vapor 
Monitor (OVM) or a Photo Ionization Detector (PID), is inserted into the bag and the relative 
concentration of total VOCs is measured and permanently recorded in a field note book.  VOC 
Page 3 of 8 
concentrations are measured using either a Thermo Electron Corp. Innova Series catalytic OVM or 
an Ion Science PhoCheck PID.  Both the OVM and PID instrumentation are periodically calibrated 
according to the manufacturer’s recommended procedures. 

The OVM and PID are qualitative tools employed to detect and estimate the concentration of 
organic or hydrocarbon vapors.  A thin probe is inserted through a small break in the seal of a 
bagged soil sample.  For the OVM, an air sample from the headspace of the bag is drawn through 
the probe into an internal chamber where the vapors are catalyzed.  The concentration of the VOCs 
is registered on a digital scale in parts per million (ppm).  For the PID, an air sample from the 
headspace of the bag is drawn across the face of a lamp causing the sample to emit photons, the 
presence of which are converted into a VOC ppm reading that is displayed.  Oxygen levels are field 
calibrated prior to each use.  VOC calibration occurs periodically depending upon use by using a 
span gas of known concentration in a process recommended by the manufacturer.   

Well Installation/Construction 

Monitoring wells are installed using hand‐operated sampling tools, a truck‐mounted drill rig, or a 
Geoprobe drilling rig depending on the depth of well and other site‐specific conditions. All 
monitoring wells are installed according to the requirements of 15A NCAC 2C‐Well Construction 
Standards.  Specifically, individual monitoring wells are constructed of 2‐inch diameter, schedule 40 
PVC casing riser and screen.  The screen interval is generally 10 to 15 feet of machine slotted PVC 
with a slot size of 0.010".  Only flush threaded joints are used.  The annulus space around the 
screen is filled with washed filter pack No. 2 sand.  The filter pack extends one to two feet above 
the top of the screen.  A one to two foot‐thick bentonite pellet seal is then placed above the filter 
pack.  The remainder of the well annulus is completely filled with a Portland (Type I/II) cement 
grout mixture.  A protective outer steel manhole, locking cap, and concrete pad is installed for each 
well. 

Type II Monitoring Well Construction  

Single‐cased monitoring wells are generally used in delineation of groundwater quality within the 
surficial aquifer.  The wells are constructed of 2‐inch diameter, schedule 40 PVC casing and screen.  
The screen interval is generally 10 to 15 feet of machine slotted PVC with a slot size of 0.010".  Only 
flush threaded joints are used.  The annulus space around the screen is filled with washed filter 
pack No. 2 sand.  The filter pack extends one to two feet above the top of the screen.  A one to two 
foot‐thick bentonite pellet seal is then placed above the filter pack.  The remainder of the well 
annulus is completely filled with a Portland (Type I/II) cement grout mixture.  A protective outer 
steel manhole, locking cap, and concrete pad are installed for each well. 

Type III Monitoring Well Construction 

Double‐cased monitoring wells are used in the delineation of groundwater quality within a deeper 
portion of the surficial aquifer or an additional aquifer (e.g. aquitard, bedrock).  A four to six‐inch 
outer casing is installed through the surficial aquifer until a sufficient depth or until the deeper 
Page 4 of 8 
aquifer is encountered.  The casing is secured with a Portland‐grout collar that is tremmied into the 
annular spaced from the bottom of the bore hole to the surface.  Once the grout has sufficiently 
cured, the bore hole is continued through the bottom of the outer casing to a depth approximately 
15 ‐ 20 feet beneath the outer casing.  The inner casing is constructed of 2‐inch diameter, schedule 
40 PVC casing riser and screen.  The screen interval is generally 5 to 10 feet of machine slotted PVC 
with a slot size of 0.010".  Only flush threaded joints are used.  The annulus space around the 
screen is filled with washed filter pack No. 2 sand.  The filter pack extends one to two feet above 
the top of the screen.  A one to two foot‐thick bentonite pellet seal is then placed above the filter 
pack.  The remainder of the well annulus is completely filled with the same Portland grout mixture 
used in the outer casing.  A protective outer steel manhole, locking cap, and concrete pad are 
installed for each well. 

Well Development 

Following installation of each well, surging and pumping or bailing techniques will be used to 
remove fines from the screened interval.  Groundwater is removed from each well until clear water 
is retrieved or a noticeable reduction in the amount of silt is achieved.  Purged groundwater is 
disposed of in an environmentally safe manner. 

Groundwater Sampling 

Petroleum Sites 

Groundwater samples are collected from temporary or permanent monitoring wells according to 
established sampling protocol.  When multiple monitoring wells or sampling points are sampled, 
sampling is completed beginning with the least contaminated well to the most contaminated well, 
if it is known.  When permanent monitoring wells for petroleum sites are sampled, the well is 
purged of a minimum of three well‐bore volumes prior to sample collection in order to assure that 
sampled water is representative of aquifer conditions.  In temporary wells, the first water which 
migrates into the open borehole is sampled.  Samples from both temporary and permanent 
monitoring wells are collected using individually wrapped disposable polyethylene bailers by field 
personnel wearing disposable nitrile gloves.  Only one well is sampled with a given bailer in order to 
prevent sample cross‐contamination.  During both well purging and sampling, proper protective 
clothing and equipment is used and is dependent upon the type and level of contaminants present. 
Also, field personnel change gloves between different samples to reduce the chance of cross‐
contamination. Water samples are transferred from the bailer to laboratory‐prepared sampling 
containers using slow emptying devices to reduce the chance of contamination loss through 
volatilization.   Preservatives, such as acids, are provided by the laboratory in pre‐prepared 
containers in which collected samples are placed if in‐field preservation is necessary.  The samples 
are labeled with the project name, project number, sample identification, required analysis, and 
date and time of collection.  The samples are placed on ice, shipped to a certified laboratory, and 
analyzed before the expiration of an analytical method’s prescribed holding time.  Chain‐of‐custody 
documentation is maintained for each sample collected in the field.   

Page 5 of 8 

Other Groundwater Sampling Protocols 

When required by state or federal regulations, low‐flow groundwater sampling procedures are 
instituted.  Groundwater samples collected in low‐flow situations are collected using a peristaltic 
pump. A peristaltic pump is a type of positive displacement pump. The fluid is contained within a 
flexible tube fitted inside a circular pump casing.  A rotor with a number of rollers attached to the 
external circumference compresses the flexible tube. As the rotor turns, the part of tube under 
compression closes thus forcing the fluid to be pumped to move through the tube.  Groundwater 
parameters such as water level drawdown, pH, conductivity, dissolved oxygen (DO) and turbidity. 
Pumping rate, drawdown, and the time or volume required to obtain stabilization of parameter 
readings can be used as a future guide to purge the well. Measurements are collected at a pre‐
pumping established interval (typically five to ten minutes). Once all or a majority of the 
parameters have stabilized for three successive readings, stabilization has been achieved. In lieu of 
measuring all five parameters, a minimum subset would include pH, conductivity, and turbidity or 
DO. Three successive readings should be within ± 0.1 for pH, ± 3% for conductivity, and ± 10% for 
turbidity and DO.  

Upon parameter stabilization, sampling is initiated. Sampling flow rate is maintained at the estab‐
lished purge rate or is adjusted slightly to minimize aeration, bubble formation, turbulent filling of 
sample bottles, or loss of volatiles due to extended residence time in tubing. The same device used 
for purging is used to collect the groundwater sample. Generally, volatile parameters are sampled 
first. The sequence in which samples for inorganic parameters are collected is not determined 
unless filtered (dissolved) samples are collected. Preservatives, such as acids, are provided by the 
laboratory in pre‐prepared containers in which collected samples are placed if in‐field preservation 
is necessary.   The samples are labeled with the project name, project number, sample 
identification, required analysis, and date and time of collection.  The samples are placed on ice, 
shipped to a certified laboratory, and analyzed before the expiration of an analytical method’s 
prescribed holding time.  Chain‐of‐custody documentation is maintained for each sample collected 
in the field.   

During both well purging and sampling, proper protective clothing and equipment is used and is 
dependent upon the type and level of contaminants present.   Also, field personnel change gloves 
between different monitoring wells or sampling points to reduce the chance of cross‐
contamination.  When multiple monitoring wells or sampling points are sampled, sampling is 
completed beginning with the least contaminated well to the most contaminated well, if it is 
known. 

Stockpile Sampling 

The number of composite samples collected from a stockpile or a total quantity of excavated soil is 
based upon the cubic yardage.  One composite sample is collected for every 100 cubic yards of 
contaminated soil excavated.  The volume of a stockpile or total quantity of excavated soil is 
calculated by approximating the general geometry of a stockpile or estimating the capacity of the 
Page 6 of 8 
dump trucks used for hauling.  If a stockpile is sampled, a grid pattern is laid out on the stockpile, 
dividing the stockpile into segments of approximately 200 cubic yards.  Two soil borings are 
advanced within a grid and three soil samples are collected from each soil boring at various depths. 
 The six soil samples are mixed into a composite sample by a trained TerraQuest technician.  If truck 
loads are sampled, an aliquot sample is collected from the hauling trucks at a frequency based 
upon the capacity of the hauling trucks.   

Aliquots are gently mixed into a composite sample by a trained TerraQuest technician. Every effort 
is made to minimize the loss of contaminants through volatilization.  The composited soil samples 
are jarred in the appropriate laboratory‐prepared containers, labeled with the sample location, 
sample identification, date of collection, time of collection, the analytical method, and the 
preservative.  The samples are placed on ice, shipped to a laboratory, and analyzed before the 
expiration of an analytical method’s prescribed holding time.  Chain‐of‐custody documentation is 
maintained for each sample collected in the field. 

Surface Water Sampling 

Surface water samples, specifically samples from creeks or streams, are collected from a 
moving/flowing portion of the creek or stream to ensure that stagnant water is not collected.  Field 
personnel are careful to collect samples from flowing areas that are not so turbulent as to cause a 
loss of volatile contaminants which might have been contained in the creek’s/stream’s water.  
Samples are collected by field personnel wearing disposable nitrile gloves.  Field personnel change 
gloves between different locations to reduce the chance of cross‐contamination.  Samples are 
collected directly from the appropriate creek or stream location and placed into the appropriate 
laboratory‐prepared containers.  Preservatives, such as acids, are provided by the laboratory in pre‐
prepared containers in which collected samples are placed if in‐field preservation is necessary. The 
samples are labeled with the project name, project number, sample identification, required 
analysis, and date and time of collection.  The samples are cooled on ice to approximately four 
degrees centigrade, shipped to a certified laboratory, and analyzed before the expiration of an 
analytical method’s prescribed holding time.  Chain‐of‐custody documentation is maintained for 
each sample collected in the field.    

Potable Well Sampling 

Groundwater samples from potable wells are collected from sampling points, typically spigots, 
located in the closest proximity to the potable well pump house as possible.  Prior to sample 
collection, the water is run for a sufficient amount of time to purge the bladder tank and assure 
that sampled water is representative of aquifer conditions.  Once purged, the flow rate is reduced 
and samples are placed in the appropriate laboratory prepared containers with the appropriate 
acid preservatives added if preservation of the sample is necessary.  The samples are labeled with 
the project name, project number, sample identification, required analysis, and date and time of 
collection.  The samples are placed on ice, shipped to a laboratory, and analyzed before the 
expiration of an analytical method’s prescribed holding time.  Chain‐of‐custody documentation is 
maintained for each sample collected in the field.  
Page 7 of 8 
Public Water Supply Line Sampling 

Groundwater samples from public water supply lines are collected from sampling points, typically 
spigots.  To sample the spigot, the flow rate is reduced and samples are placed in the appropriate 
laboratory prepared containers.   The samples are labeled with the sample location, sample 
identification, date of collection, time of collection, and required analytical method.  The samples 
are placed on ice, shipped to a laboratory, and analyzed before the expiration of an analytical 
method’s prescribed holding time.  Chain‐of‐custody documentation is maintained for each sample 
collected in the field.  

Air Sampling 

Air samples are collected with the aide of a manually operated MityVac® pump manufactured by 
Pristech, Inc.  The air sampling process begins by connecting a length of rubber hose from the 
MityVac® pump to the port to be sampled, or by hanging the hose inside of an emissions stack in 
such a manner as to ensure no outside air causes dilution.  Another length of hose is fixed to the 
outlet port of the pump and is connected to a new Tedlar bag.  Once the pump is hooked up, a 
valve on the Tedlar collection bag is opened and air is manually forced into the bag by the pumping 
action of sampling personnel.   

Field Measurements 

Field measurements taken to determine the pH, conductivity, temperature, and dissolved oxygen 
concentration of a particular groundwater sample are taken directly after a particular monitoring 
well has been adequately purged.  This ensures that the groundwater parameter data collected is 
representative of the aquifer conditions at a given location.  Once purging of the monitoring well is 
complete, the decontaminated probe head and cord of the appropriate unit is lowered into the 
required monitoring well.  If the depth to water in a specific monitoring well is greater than the 
length of cord for a particular unit, a new, disposable bailer is slowly lowered into the appropriate 
monitoring well and a representative groundwater sample is retrieved.  A slow pouring device is 
fitted onto the end of the disposable bailer and the sample is slowly poured into a new, disposable 
plastic cup.  Groundwater parameter data are then collected from the groundwater in the cup 
using the required unit.   

For pH, conductivity, and temperature, a Hanna Instruments Model 991300 portable meter is 
utilized.  This unit is periodically calibrated and maintained in accordance with the unit’s operations 
manual by field personnel.  Prior to data collection, the unit is properly decontaminated to prevent 
cross‐contamination.  The unit is decontaminated between each sample.  The procedure used for 
sample measurement involves lowering the meter’s probe into the new, disposable cup containing 
the groundwater sample to be measured and slowly stirring the probe to force groundwater across 
the probe’s membrane.  The measurements displayed by the meter are then recorded.   

For dissolved oxygen concentration measurements, a YSI® Model 55 Handheld Dissolved Oxygen 
System is utilized.  This unit is periodically calibrated and maintained in accordance with the unit’s 
Page 8 of 8 
operations manual by field personnel.  Prior to data collection, the unit is properly decontaminated 
to prevent cross‐contamination.  The unit is decontaminated between each sample.  The procedure 
used for sample measurement involves adjusting the unit for the correct altitude where the 
sampling will take place and adjusting the reported units desired.  Once this is done, the unit’s 
probe is inserted into the groundwater sample to be measured and the probe is slowly stirred to 
force the groundwater across the probe’s membrane.  The measurements displayed by the unit are 
then recorded.   

For turbidity measurements, a Hach 2100P Portable Turbidity meter or equal equivalent is utilized.  
The unit is calibrated prior to use in accordance with the unit’s operations manual by field 
personnel.  Groundwater samples are collected in glass containers for measurement by the 
instrument.  The glass containers are washed with bottled‐water between each measurement 
collection.  Once the sample is collected and inserted into the instrument, the measurements 
displayed by the instrument are then recorded.

Receipt
The samples were received on 12/2/2022 9:02 AM. Unless otherwise noted below, the samples arrived in good condition, and, where
required, properly preserved and on ice. The temperature of the cooler at receipt time was 9.6°C
Receipt Exceptions
The following samples were received at the laboratory outside the required temperature criteria: TQMW1 (400-229832-1), TQMW2
(400-229832-2), TQMW3 (400-229832-3), TQMW4 (400-229832-4) and TQMW5 (400-229832-5). The client was contacted regarding this
issue, and the laboratory was instructed to proceed with the analysis.
GC/MS VOA
Method SM6200_B: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for analytical batch 400-603986 were outside control
limits for one or more analytes. Sample matrix interference is suspected because the associated laboratory control sample (LCS)
recovery is within acceptance limits.
Method SM6200_B: The following samples were diluted to bring the concentration of target analytes within the calibration range: TQMW1
(400-229832-1) and TQMW2 (400-229832-2). Elevated reporting limits (RLs) are provided.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
