EXECUTIVE SUMMARY
On behalf of Lighthouse Food Mart, Inc., Terraquest Environmental Consultants, P.C. is reporting
the results of monitoring efforts associated with the UST petroleum release at the Lighthouse
Food Mart No. 110 facility located in Kinston, Lenoir County, NC. A release of gasoline from the
previous LIST system is a High Risk due to the presence of nearby sensitive receptors. Analytical
results for the July 22, 2019 groundwater sampling event revealed the continued presence of
petroleum-type contaminants at concentrations in excess of the 2L Standards, however, the
plume is stable, no GCL violations are present, and no petroleum-type contaminants were noted
in the downgradient, offsite monitoring well. Terraquest recommends the filing of a NORP and
issuance of an NFA.

1.0 INTRODUCTION
On behalf of the responsible party, Lighthouse Food Mart Inc., Terraquest Environmental
Consultants/ P.C. has prepared this Monitoring Report for the Lighthouse Food Mart No. 110
facility located in Kinston, Lenoir County, North Carolina. The site has been ranked a High Risk
H163R by the NCDWM-UST based upon the presence of a municipal water supply well within
1,000 feet of the release area. This report documents the groundwater monitoring event that
occurred on July 22, 2019. Activities detailed in this report were pre-approved on ePATA 31302-
032.
The site location is depicted in Figure 1. Figure 2 is a site vicinity map that identifies potentially
sensitive receptors within a 1,500-foot radius of the site. The site layout and monitoring well
locations are depicted in Figure 3. Environmental acronyms used in this report are detailed in
Appendix A along with Terraquest's technical methods and standard procedures. A detailed
chronological site history is provided in Appendix B.
2.0 SITE HISTORY AND CHARACTERIZATION

Report Prepared: August 6, 2019 iii 2777 HWY 55 E, Kinston, NC
3. Non-UST Information
No non-UST release incidents are documented at this site.
4. Release Description
According to Judy Jenks of Lighthouse, water was noted in LIST T2 during the normal inventory
gauging process in early May 2004. A tank tightness test was subsequently performed on LIST T2
and LIST T3 by National Tank Monitor Incorporated of Charlotte, NC, an independent tank
tightness testing company, on May 16, 2004. The results of the tank tightness test indicated that
UST T2 failed the test and UST T3 passed the test. On June 10, 2004, Superior Services of
Hendersonville, NC inspected in the interior of LIST T2 and found a hole in the bottom of the LIST.
Superior subsequently repaired the hole. The estimated quantity of petroleum released to the
subsurface from the UST is unknown.
5. Site Characteristics
Land usage in the surrounding vicinity is a mixture of commercial, agricultural, and residential.
The closest residence is located on the site property in a mobile home trailer approximately 180
feet from the source area. Residential property is randomly located in all directions of the site
except to the southeast. The majority of commercial property is immediately located to the
south and east of the site. Properties immediately surrounding the site to the north, west,
southeast, and southwest are primarily wooded or fields for agriculture. A trucking facility is
located immediately south of the site. A Piggly Wiggly shopping center is located east-northeast
of the site. Zoning in the area, from Lenoir County GIS, is as shown on the figure on the following
page. Properties in the surrounding vicinity are zoned residential (yellow), and commercial (red).

6. Regional and Site Geolofiy and HydroReologvAccording to the Geologic Map of North Carolina, the site overlies the Peedee Formation of theCoastal Plain Physiographic Province. The Peedee Formation is primarily composed of sand,clayey sands, and clays (Brown, et al., 1985).The following lithologies were encountered at the site during the installation of soil borings andthe monitoring well network:0' - 20' below ground level (BGL):CLAYEYSAND(SC)Loose, light brown/tan in color, mostly fine to medium sand grains, few to littleclay.20'-45'BGLSANDY CLAY (CL)Soft, dark gray in color, mostly clay with some fine grained sand and few roundedquartz gravel.45'- 47' BGLCLAYEYSAND(SC)Loose, dark gray in color, mostly fine sand grains with some clay.Generalized subsurface lithologies are shown on the following page in the following geologiccross-sections:Groundwater Monitoring Report (7/22/19 event) Lighthouse Food Mart, Inc.By: Terraquest Environmental Consultants, P.C.

On a regional scale, the Coastal Plain is characterized by land with little relief and some areas oflow relief hills and valleys. The local topography is characterized by relatively flat topographywith little relief. The entire area surrounding 1,000 feet of the site is mapped at 25 five feetabove sea level. Local topography is depicted in Figure 1.The release area is overlain by concrete, asphalt, gravel, and grass. Precipitation which falls onthe uncovered portions of the site infiltrates the underlying soils. Excess runoff and shallow soildrainage is directed toward several storm sewer grates located around the property.While no perennial surface water body was noted within 500 feet of the site, drainage ditcheswere noted along Highway 11 and 55. The closest perennial surface water body is the NeuseRiver located approximately 6,000 feet north of the site.Historical groundwater flow at the site decreases to the east-northeast. The water tablefluctuates with historical mins and max depth to water measurements ranging between 3 and 9feet BGL. The most recent groundwater flow map is provided as Figure 4. Historical groundwaterelevation data is provided in Appendix C.Water level data from the Type III monitoring well (MW5) and the interpreted groundwaterelevation in the phreatic aquifer in the vicinity of the Type III well were used to determine if avertical head gradient existed in the phreatic aquifer. The vertical gradient was calculated usingthe following equation and groundwater elevation data collected on September 16,2008:•phreatic II' MV 5where: DVg = Vertical head gradientHphreatic = Water elevation in the shallow aquifer near MW5 = 92.80'HMWS = Water elevation in deep well MW5 = 79.46'Groundwater Monitoring Report (7/22/19 event) Lighthouse Food Mart, Inc.By: Terraquest Environmental Consultants, P.C. Lighthouse Food Mart No. 110Report Prepared: August 6, 2019 viii 2777 HWY 55 E, Kinston, NC
D = The difference in elevation between the shallow water table and themiddle of the well screen in MW5 = (92.80' - 54.81') = 37.99'therefore:V.=92'801-79'46'- +0.35'g 37.99'The head gradient suggests a recharging hydrologic flow gradient meaning groundwater tends toflow in a downward direction. A review of regional topographic maps affirms this belief. Withincreasing depth and distance from the recharge area, the flow lines flatten out and becomemore horizontal than vertical. Eventually, as the flow lines near lower elevations, the flow linescurve upward towards the ground surface into areas of discharge such as streams and rivers.Terraquest performed rising head slug tests on monitoring wells MW4, MW10, MW13, andMW14 on November 30, 2007. The slug tests revealed hydraulic conductivity estimates rangingfrom 0.66 to 1.3 feet per day. Using an effective porosity of 25 percent and an average hydraulicconductivity of 1.39 feet/day, Terraquest calculated the linear velocity of groundwater to be 7.3feet/year.7. Surrounding Property Owners and OccupantsSurrounding property owner information is provided in Table 2.8. Critical ReceptorsAs part of LSA activities, a reconnaissance of surrounding properties was performed to identifyany sensitive contaminant receptors. The main receptor identified was a production watersupply well operated by the Deep Run Water Corporation. The Deep Run Well #7 provides waterto the majority of residences and commercial properties in the surrounding area and is locatedapproximately 800 feet southeast of the release area. A 2,000-foot well head protection area(WHPA) has been established for the well in accordance with 42 United States Code (USC) 300h-7(e). The WHPA encompasses the site property. Five other potable wells were identified withinGroundwater Monitoring Report (7/22/19 event) Lighthouse Food Mart, Inc.By: Terraquest Environmental Consultants, P.C. Lighthouse Food Mart No. 110Report Prepared: August 6, 2019 ix 2777 HWY 55 E, Kinston, NC
1/500 feet of the site. Only one of those wells is used as a sole source of potable water; the otherproperties are connected to the Deep Run Well #7. Well locations are shown on Figure 2 andfurther information is provided in Table 3.9. Summary of CAP ImplementationThe CAP for the release incident/ approved by the NCDWM-UST, called for the continuedmonitored natural attenuation aided by MMPE events to reduce spikes in contaminantconcentrations. In addition, a second type III vertical monitoring well (MW22) was installed forfurther investigation into the vertical extent of contamination. Between March 2009 and March2012, Terraquest supervised the completion of seven weeks of MMPE events at the site thatsuccessfully removed 135.58 gallons of LNAPL and nearly 123,000 gallons of petroleum-contaminated water. Groundwater monitoring events were conducted at an approximate semi-annual interval.In May 2011, the NCDWM-UST, requested the completion of a New Technology Cleanup Plan(NTCP) to determine whether or not MMPE events were the most cost effective form ofremediation or whether an alternative method should be investigated. Based upon review ofhistorical groundwater analytical results, coupled with contaminant fate and transport modeling,the findings of the NTCP confirmed MNA aided by MMPE events as a cost effective remedialmethod.In an NORR dated December 7, 2012, the NCDWM-UST acknowledged the decrease ofcontaminant concentrations from the most recent groundwater monitoring event and requestedno additional active remediation (MMPE events) be conducted.10. ReportingReports have been prepared and submitted to the NCDWM-UST regarding the release incidentat various project stages. Some of those include: Site Check Report; LSA, CSA, Monitoring Report,and Corrective Action Plan.Groundwater Monitoring Report (7/22/19 event) Lighthouse Food Mart, Inc.By: Terraquest Environmental Consultants, P.C.

3.0 SOIL QUALITYFollowing the May 2004 release discovery, and repair of the hole in LIST 2 in June of 2004,Terraquest personnel supervised the advancement of eight (8) soil borings around USTs T2 andT3 on June 16, 2008. Soil boring locations are depicted in Figure 5. The collected soil sampleswere analyzed per TPH 5030 targeting low boiling point fuels. Table 4 lists sampled borings andselected intervals. Analytical results from the soil samples revealed petroleum contaminantconcentrations in soil samples SB1, SB3 -SB5, SB7, and SB8. Samples SB1 and SB3 were the onlysamples with concentrations above the historical NCDWM-UST action limit of 10 mg/kg withconcentrations of 2/000 mg/kg and 12 mg/kg, respectively. The analytical results of the soilsamples are summarized in Table 4.On August 4, 2004, Terraquest supervised the removal of 15.97 tons of contaminated soiladjacent to UST 2 and LIST 3. Three sidewall soil samples, SS1, SS2, and SS3, were collected fromthe limits of the excavation and submitted for laboratory analysis per EPA Method 8260 and perMADEP VPH. The analytical results did not reveal the presence of any STG MSCC violations in anyof the three samples. The analytical results of the soil samples are summarized in Table 4 andthe locations are shown on Figure 5.In April 2012, the NCDWM-UST asked Terraquest to investigate the smear zone and upper aquifermaterial within the core of the plume to determine if an apparent area of soil with a low hydraulicconductivity exists, causing persistent groundwater contamination. To assess smear zone andupper aquifer contamination and the impact it may be having on groundwater quality, Terraquestadvanced twenty (20) soil borings (B9 - B28) on April 24, 2012 in the area surrounding the USTs.Each soil boring was advanced to a total depth of 10 feet BGL. Three soil samples were collectedfrom each soil boring. The first sample was collected from the 3-4 feet BGL interval, whichencompassed the historically shallowest water elevation from monitoring well MW1 measuredat 3.22 feet BGL. The second sample was collected from the 4 - 5 feet BGL interval, whichencompassed the current depth to water measurement from MW1. The third soil sample wascollected from a one foot interval between 6 feet and 10 feet B6L. The interval selected forGroundwater Monitoring Report (7/22/19 event) Lighthouse Food Mart, Inc.By: Terraquest Environmental Consultants, P.C.

sampling was based on PID readings and/or a high clay content, capable of retaining largequantities of dissolved-phase contamination. Samples submitted for laboratory analysis peranalyzed per TPH 5030 targeting low boiling point fuels. Soil boring locations are depicted onFigure 6.TPH concentrations above the historical 10 mg/kg action limit were reported in the deepestsampled intervals from soil borings B10,B13,B14,B16, B19, B20/ B22,and B25. These boringsare all located within 10 feet of the USTs. The sample collected from B19 between 8 and 9 feetBGL contained the highest concentrations of TPH with a reading of 9,400 mg/kg. Table 5summarizes soil sampling results.On October 1-2, 2012, Terraquest personnel supervised the excavation of 91.96 tons ofvadose-zone soil and aquifer material. The goal of the excavation was to speed natural attenuationprocesses by removing additional core contamination from the smear zone and upper portion ofthe phreatic aquifer. The limits of excavation, shown on Figure 7, were previously determinedthrough soil boring advancement and laboratory analyses of the retrieved samples. Theexcavation was advanced to a depth of 15 feet BGL.To date, soil sampling results show no in-situ soil contamination above STG MSCCs remaining onthe site.4.0 GROUNDWATER FLOW DIRECTIONPrior to purging and sampling the monitoring well network on July 22, 2019, Terraquestpersonnel first measured the depth-to-water in select wells. Those measurements were used inconjunction with previously established top of casing elevations to determine the direction ofgroundwater flow. Figure 4 was generated to show the potentiometric surface which isdecreasing to the east-northeast as it has been historically. Groundwater elevation data issummarized in Table 6 along with well construction information.

elevation data is contained in Appendix C that shows the recent water table is 2.2 feet lower thanthe last event (January 2019).5.0 GROUNDWATER SAMPLINGOn July 22, 2019, Terraquest personnel sampled monitoring wells pre-approved by the NCDWM-UST including MW1A, MW2-9, MW13, MW14, MW17, MW18/ and MW19. Prior to sampling themonitoring wells, each well was purged of at least three well volumes of water using a newdisposable bailer. Samples were retrieved from the monitoring wells using the same bailers. Allsamples were placed into the appropriate laboratory-prepared containers and placed on icependingshipmenttoa North Carolina-certified laboratory for analysis. Each samplewas analyzedfor volatile organic compounds by EPA method 6200B.The analytical results of the July 22, 2019 sampling event revealed the following regardingpetroleum-type compounds:>GCL None> 2L Standards: MW1A/ MW2, MW3, MW7, MW17<2L Standards: MW4, MW5, MW6, MW8, MW9, MW13, MW14/ MW18, MW19Review of the recent groundwater analytical results reveals a plume similar to those reportedhistorically.

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 isdecontamination performed less frequently
than once pertest (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 duringthe 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 1 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 forthe 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 mLvials (one 5-gram allotment pervial,2vials 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 scalable 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 scalable 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 lonization 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 2 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 headspaceofthe bag is drawn through
the probe into an internal chamber where the vapors are catalyzed. The concentration of the
VOCsis registered on a digital scale in parts per million (ppm). Forthe 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 aVOCppm readingthat 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 aslotsizeofO.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. Aonetotwofoot-thickbentonite pellet seal is then placed above the filter
pack. The remainder of the well annulus is completely filled with a Portland (Type 1/11) 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 1/11) 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 ofthesurficial aquiferoran 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 3 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 ofsilt 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 accordingto
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 polyethylenebailers 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 4 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 ofvolatiles 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 ifin-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 holdingtime. 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
PageS 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 TerraQ.uest 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 holdingtime. 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/fl owing 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 ifin-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 holdingtime. Chain-of-custody documentation is
maintained for each sample collected in the field.
Page 6 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, dateof 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 holdingtime. 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. Priorto 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.
Page 7 of 8
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
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 adjustingthe unitforthe 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.

The NCDWM-UST WaRO issued a NORR to Lighthouse Food Mart,
Inc. requiring the completion of an LSA.
Terraquest personnel installed the Type II monitoring wells MW2,
MW3, and MW4 to investigate groundwater quality in the general
vicinity of the LIST system. Monitoring well MW2 was installed in
the interpreted upgradient direction from the source of
contamination. MW3 and MW4 were installed in the interpreted
downgradient directions. Each of these monitoring wells was
installed to a depth of 13 feet B6L using a hollow-stem auger
drilling method and was constructed of Schedule 40, two- inch
diameter PVC. The screened interval for the monitoring wells was
installed bracketing the water table using eleven feet of screened
casing from two to thirteen feet BGL.
Terraquest personnel supervised the installation of one Type III
monitoring well (MW5). MW5 was installed with a six-inch
diameter PVC outer casing that terminated at 25 feet BGL. The
casing was installed to "case off" the contamination of the upper
portions of the phreatic aquifer. The day after the annulus
surrounding the outer casing had been grouted; an inner casing
was installed to a depth of forty seven feet BGL/ with a screened
interval from forty-two to forty-seven feet. This screen interval
allows for the discrete sampling of a deeper portion of the
aquifer. The benefit of such sampling is the investigation of
groundwater quality in a vertical direction.
Terraquest personnel sampled monitoring wells MW2 - MW5
using the same purging and sampling techniques previously
discussed for monitoring well MW1. Groundwater samples from
the monitoring wells were submitted for analysis per EPA
Methods 6210D+MtBE+IPE, 504.1 EDB, 6010B for lead by a 3030C
digestion method, and MADEP method VPH for gasoline-type
contaminants.
October 2004 A Limited Site Assessment Report was submitted to the NCDWM-
UST.
Novembers, 2004
May 21, 2007
The NCDWM-UST issued an NORR ranking the site a High Risk but
due to Session Law 2004-124, no work was directed.
The NCDWM-UST issued Lighthouse Food Mart, Inc. an NORR
requesting the completion of a CSA since the site's ranking was
sufficient for such directed work.

free product, the conduction of a pre-cap groundwater sampling
event, and the preparation of a Corrective Action Plan.
An MMPE event was conducted at the site to remove free product
and contaminated groundwater. ZAVA Industrial, Inc. of
Burlington/ NC was hired to provide equipment and personnel for
the event. The MMPE event was successful at removing 7,230
gallons of contaminated groundwater and 135.58 gallons of free
product. A check at the conclusion of the event revealed that free
product had been reduced to below a measurable thickness.

Flagging Criteria
X In our quality control review of the data a QC deficiency was observed and flagged as noted. MS/MSD recoveries were found to be
outside of the laboratory control limits due to possible matrix /chemical interference, or a concentration of target analyte high enough
to affect the recovery of the spike concentration. This condition could also affect the relative percent difference in the MS/MSD.
B A target analyte or common laboratory contaminant was identified in the method blank. Its presence indicates possible field or
laboratory contamination.
D The sample(s) were diluted due to targets detected over the highest point of the calibration curve, or due to matrix interference.
Dilution factors are included in the final results. The result is from a diluted sample.
E The data exceeds the upper calibration limit; therefore, the concentration is reported as estimated.
F RPD exceeded lab control limits.
J The target analyte was positively identified below the quantitation limit and above the detection limit.
U Analyte was not detected.
L The LCS data for this analytical batch was reported below the laboratory control limits for this analyte. The department supervisor and
QA Director reviewed data. The samples were either reanalyzed or flagged as estimated concentrations.
H The LCS data for this analytical batch was reported above the laboratory control limits. Supporting QC Data were reviewed by the
Department Supervisor and QA Director. Data were determined to be valid for reporting.
K Sample analyzed outside of recommended hold time.

JN A combination of the "N" and the "J" qualifier. The analysis indicates that the analyte is "tentatively identified" and the associated
numerical value may not be consistent with the amount actually present in the environmental sample.
** Surrogate recovered outside laboratory control limit.
BRL Below Reporting Limit.
