EXECUTIVE SUMMARY

Terraquest has conducted a groundwater sampling event for the A-1 Superette release incident
located in Hickory, Catawba County, North Carolina. The work was performed for the responsible
party, RJ Shell & Son, Inc.

The A-1 Superette release incident is ranked an Intermediate Risk based on the presence of GCL
violations that have been reduced by a December 2021 injection event and subsequent MMPE
events. An August 3, 2023 groundwater sampling event confirms the presence of GCL violations in
three wells at the site. Those three wells are located in aquifer material that was not accepting to
the injectant and is presumably too tight. While MMPE was marginally effective at removing
contaminated groundwater, it is an expensive option that hasn’t shown large changes. Terraquest
recommends the addition of the injectant successfully used across the site, Oxygen Biochem, into
boreholes advanced in the aquifer throughout the areas of remaining contamination exceeding the
GCLs. Follow-up groundwater sampling would be conducted thereafter.

1.0 INTRODUCTION

On behalf of the responsible party, RJ Shell & Son, Inc. (RJ Shell), Terraquest Environmental
Consultants, P.C. has performed environmental assessment activities at the A-1 Superette facility
in Hickory, Catawba County, North Carolina. The assessment relates to a release of petroleum
from the former onsite UST system. Specifically, this report documents the August 3, 2023
sampling event. It is the fifth sampling event conducted following the December 2021 Oxygen
Biochem injection event and follows the July 2023 MMPE event. The work was requested by the
North Carolina Division of Waste Management’s Underground Storage Tank Section (NCDWM-
UST). The costs were pre-approved on ePATA 27493-030.

The site location and surrounding cultural features are depicted in Figure 1. The site vicinity is
depicted in Figure 2. The site layout and monitoring well network are depicted in Figure 3.
Technical methods and standard procedure generally used by Terraquest personnel are outlined
in Appendix A. A chronological history of site events is provided in Appendix B.

2.0 SITE HISTORY AND SOURCE CHARACTERIZATION

UST Owner:
The USTs were owned by RJ Shell & Son, Inc.

UST Information:
According to the NC UST Database Records and site observations, three 4,000-gallon gasoline,
one 10,000-gallon gasoline, one 2,000-gallon diesel USTs were installed at the site on March 4,
1980. Note that the 10,000-gallon kerosene, and one 550-gallon heating oil USTs. All USTs were
closed via excavation and removal in August 2019 as previously reported. A site history of the
USTs on the property is included as Table 1. Previous tank locations are shown on Figure 3.
Terraquest is not aware of any AST release incidents.

The site and the surrounding properties derive their drinking water from the city of Hickory’s
municipal water supply system. Previous reconnaissance efforts by others did not identify and
water supply wells within 1,000 feet of the source area.

According to the Geologic Map of North Carolina (Brown et al, 1985), the site is located in the
Inner Piedmont Belt of the Piedmont Physiographic Region of North Carolina and is underlain by
biotite gneiss and schist. Consolidated bedrock was not encountered during Terraquest’s
assessment to date. The closest surface water body is Barger Branch located approximately
1,400 feet to the east-northeast of the release area. The location of the stream is depicted on
the site’s location map, included as Figure 1, on the USGS topographic quadrangle of Hickory, NC.

3.0 SOIL ASSESSMENT

Soil quality has been investigated through the 2003 Site Check, 2003 LSA, 2012 CSA, the 2019
UST closure, and the 2019 over-excavation. The sample results are summarized on Tables 3, 4,
5, 6, and 7. The sample locations are shown on Figures 3, 4, 5, and 6.

Site Check (Table 3, Figure 4):
As part of the 2003 site check performed by Allied Environmental Services, PLLC (AES), thirty-
eight (38) samples were collected around the UST system. The analytical results indicate the
presence of soil contamination at the gasoline USTs, product lines, and dispenser and at the
kerosene UST, product line, and dispenser.

LSA (Table 4, Figure 3):
Further soil assessment was conducted as part of the LSA by AES in October 2003. During
installation of the monitoring wells, soil samples at multiple vertical levels were collected from
monitoring wells MW1-MW5 and submitted for analysis per 8260 and MADEP VPH and EPH. The
analytical results revealed the presence of soil-to-groundwater maximum soil contaminant

concentration (STG MSCC) violations in samples from MW1, MW2, and MW3. No violations were
reported for the samples from monitoring wells MW3, MW4, nor MW5.

CSA (Table 5, Figure 3):
In December 2012, as part of CSA efforts by ARM Environmental Services, Inc. (ARM), soil samples
were collected from monitoring wells MW6 – MW10 and submitted for laboratory analysis per
8260, MADEP VPH, and TPH GRO by ARM Environmental Services (ARM). The sample locations
were located between 30 and 115 feet away from the UST system. None of the samples had
petroleum-type compounds reported over the method detection limit.

UST Closure (Table 6, Figure 5):
Following removal of USTs T1-T4 and heating oil UST T5 in August 2019, Terraquest collected soil
samples to document UST closure. Three soil samples were collected from native soils beneath
each commercial tank and one below the heating oil tank (CS1 – CS12, and CS15 for the heating
oil UST). Closure soil samples were analyzed onsite utilizing Site Lab’s Trilogy UVF machine
targeting both TPH GRO and TPH DRO contaminant concentrations. Analytical results of closure
soil samples revealed TPH concentrations in excess of the Action Limits in CS1 – CS11. Detected
contaminant concentrations in the CS12 closure soil sample (western end of T4) and CS15
samples did not exceed Action Limits.

UST Basin Excavation (Table 7, Figure 6):
On August 21, 2019 Terraquest personnel supervised the excavation of 172.77 tons of
contaminated soil from the eastern end of UST T4 and southern ends of T1 – T3. The horizontal
extent of the excavation did not exceed the area disturbed during tank closure. The final depths
of the excavation ranged from 20 feet BGL beneath the central and eastern end of UST T4 to 15
feet BGL beneath the central and southern portions of USTs T1- T3.

At the conclusion of the soil excavation six sidewall samples (SW1 – SW6) and two base of
excavation samples (BE1 & BE2) were collected to document in-situ soil quality. The analytical

By: Terraquest Environmental Consultants, P.C. 1110 S. Center St
Prepared: March 2, 2023 6 Hickory, Catawba County, NC
results showed in-situ soil contamination above the STG MSCCs in the sidewall samples SW4,
SW6, and base of excavation sample BE1. Detections of contaminant concentrations in the
remaining samples did not exceed the STG MSCCs.

4.0 FREE PRODUCT ASSESSMENT

Free product has not been encountered by Terraquest throughout assessment. In their 2012
report, ARM reported the presence of 0.05 feet of free product in monitoring well MW4. None
was gauged in that well during the August 3, 2023 visit.

5.0 GROUNDWATER ASSESSMENT

Groundwater remediation was conducted via an Oxygen Biochem injection in December 2021 at
this site. Following that event, a groundwater sampling was conducted on January 27, 2022 and
again in March 2022. Favorable results were reported. However, following the August 18, 2022
sampling event, Terraquest and the NCDWM-UST agreed to conduct a Mobile Multi-Phase
Extraction event to help remove GCL violations in the areas around monitoring wells MW4,
MW11, MW12, and MW14. Those areas did not accept the injection as well and contamination
remained above GCLs. An MMPE performed between January 16 and 20, 2023 removed 4,520
gallons of contaminated groundwater. A second MMPE was conducted from July 17-21, 2023.
The August 3, 2023 sampling event detailed herein followed that second MMPE.

Groundwater flow:
Prior to purging and sampling the monitoring well network on August 3, 2023, Terraquest
personnel first measured the depth to water in each well. Those measurements have been used
with previously established casing elevations to generate the potentiometric surface map
presented as Figure 7. That map shows groundwater flow toward monitoring wells MW11 and
MW14. Historically, groundwater flow has been to the west and east. The recent measurements
are presented along with well construction information in Table 8. Historical groundwater data

is provided in Appendix C that shows groundwater is about 0.22 feet lower than when measured
last in February 2023.

Groundwater quality:
On August 3, 2023, Terraquest personnel collected groundwater samples from monitoring wells
requested by the NCDWM-UST including, MW3, MW4, MW6, MW9, MW11, MW12, MW14, and
AS1. 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. Monitoring well MW4, located near the former kerosene dispenser, was also
analyzed for semi VOC’s by method 625 BNA.

Prior to discussing the February 2023 results, a review of prior results is warranted to better
understand progress at this site toward closure. Generally, the December 2021 injection of OBC
was an overwhelming success. The following “before and after” was noted:

6.0 CONCLUSIONS / RECOMMENDATIONS

The A-1 Superette release incident is ranked an Intermediate Risk based on the presence of GCL
violations that have been reduced by prior injection and MMPE events. However, the
contamination in areas that were too tight for injection appears to remain relatively the same.
While Oxygen Biochem (OBC) was very successful where it could be pumped in, the areas around
MW11, MW12, MW14, and AS1were too tight and remain contaminated above the GCLs.

Terraquest recommends the addition of the injectant into boreholes advanced in the aquifer
throughout the areas of remaining contamination exceeding the GCLs. The proposed drill
locations are shown on Figure 9. Auger drilling would be used to drill the boreholes and then
OBC would be added into the aquifer. The boreholes, penetrating into the aquifer, would then
require backfilling with grout per the 2C regulations. This would leave a volume of drill cuttings
that would require offsite disposal. Following drilling and allowing several months for the OBC
to disperse, groundwater quality would be checked with follow-up sampling.

7.0 LIMITATIONS

This report is limited to the investigation of petroleum-type compounds 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, elevations, and water
quality may very through time. The opinions and conclusions arrived at in this report are in

 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.
