The property has an old NCDWM-UST Incident No. of 10586 that was closed in August 2001. The current assessment is related to arelease of petroleum from a broken product line fitting discovered and repaired in late 2013. Terraquestdoes not believe this release was reported to the NCDWM-UST; therefore, a UST-61 24-hr ReportingForm is attached with this letter and report.One monitoring well was installed adjacent to the repaired product line and a sample was collected.When the well was gauged several days later, 0.18 feet of LNAPL was observed. As part of field workactivities, a receptor survey was conducted and no potential receptors were identified within 1,000 feet.Terraquest recommends the current release incident be ranked an Intermediate Risk with a Residentialland-use classification.If you have any questions regarding the report or the project, please contact us at [phone].Thank you for your assistance in this project.Sincerely,TERRAQUEST ENVIRONMENTAL CONSULTANTS, P.C.i^'^tA r.A&l'^^k..s€d^G^o^'^w.^'^''»t'i'i7t^"llvJonathan R.

1.0INTRODUCTIONOn behalf of Saleh Properties ofWilson, LLC, the property and underground storage tank (LIST)owner, Terraquest Environmental Consultants, P.C. (Terraquest) has prepared this Site Check &Limited Site Assessment (Phase I) Report for the On The Run facility located in Wilson, WilsonCounty, North Carolina. This report has been prepared to comply with those requirements setforth under Title 15A of the NCAC Subchapter 2L Section .0405.The site location is shown in Figure 1. Figure 2 is a site vicinity map depicting properties within1,500 feet of the site. A site layout map is included as Figure 3. Environmental Acronyms andTechnical Methods and Standard Procedures utilized byTerraquest personnel in this report andduring the groundwater sampling process are detailed in Appendix A.2.0 SITE HISTORYSaleh Properties of Wilson, LLC purchased the property at 739 Ward Boulevard on January 6,2011. The current LIST system on the property consists of three 10,000-gallon gasoline, one4,000-gallon diesel, and one 4,000-gallon kerosene USTs each installed in 1987. The firstgeneration of tanks on the property consisted of four 4,000-gallon gasoline, one 4,000-gallondiesel, and one 4,000-gallon kerosene USTs, all of which were removed in 1987. A site historyof the USTs located on the site is included as Table 1. Current tank locations are shown onFigure 3. The site is currently operated as a retail fuel facility and convenience store.The On The Run facility formerly operated under the name of Conoco Store No.33054. On June10, 1993 a release of petroleum was reported to the NCDWM-UST Section where a ReleaseIncident No. of 10586 was issued. Through years of assessment and corrective action, therelease incident was closed on August 31, 2001. At the time of incident closure the release wasranked a Low Risk and groundwater contamination did not exceed GCLs. Further informationLimited Site Assessment Report-Phase IPrepared by: Terraquest Environmental Consultants, P.C.Report Prepared: 5/25/18Saleh Properties ofWilson, LLCOn The Run - 739 Ward BoulevardWilson, Wilson County, NC
regarding the property's previous release incident is on file with the NCDWM-UST RaleighRegional Office.On November 5, 2013, Precision Tank Service, Inc. completed a line and lead detection test forthe mid-grade LIST and lines. The test resulted in failure as the LD test estimated the lead rateat 3.0 gallons per hour. To more thoroughly investigate the exact point of line break, a heliumtest was conducted by Precision Tank Service on November 12, 2013. The helium testsuccessfully identified a broken pipe fitting near the middle dispenser. The broken fitting wasreplaced, and the LIST system has passed all subsequent Line/LD tests. Based upon theavailable information, the cause for the release has been identified, rectified, and is no longeran ongoing issue. Through file review and discussions with the current LIST system owner, noformal reporting of this release has been completed.On December 18, 2017, ATC Group Services, LLC completed field activities as part of a Phase IIESA. Field activities included the advancement of four soil borings that were converted intotemporary monitoring wells. Each boring/temporary was installed around the canopy: SB-1(north of canopy), SB-2 and SB-3 (east of canopy), and SB-4 (south of canopy/ adjacent to USTs).One soil sample was submitted for laboratory analysis from SB-3 (0.5'-2.5/). Results revealeddetections of contaminant concentrations that do not exceed S-t-G MSCCs. Groundwatersamples were collected from each temporary well. Groundwater analytical results showedcontaminant concentrations exceeding 2L Standards in the SB-2, SB-3, and SB-4 samples. Whencompared to historical results, levels in the SB-3 groundwater sample were significantly higherthan those observed at the same location during assessment of the previous release incident. Itwas ATC's conclusion that a second release from the LIST system had occurred.Limited Site Assessment Report-Phase IPrepared by:Terraquest Environmental Consultants, P.C.Report Prepared: 5/25/18Saleh Properties ofWilson, LLCOn The Run - 739 Ward BoulevardWilson, Wilson County, NC
3.0RISK CHARACTERIZATION AND RECEPTOR INFORMATIONIn order to determine the risk classification of the site, Terraquest personnel performed areconnaissance of properties within a 1,000-foot radius of the source area. The reconnaissanceeffort consisted of obtaining tax department and local zoning information on properties andconducting door-to-door visits of certain properties within 1,000 feet of the source area, inaddition to collecting other pertinent information from the appropriate local and state officials.Terraquest personnel inspected all properties within 1,000 feet of the site for water supplywells and contacted the City of Wilson's municipal water department about the availability ofmunicipal water to the vicinity.Through the reconnaissance efforts, no water supply wells were identified within 1,000 feet ofthe source area. The site and surrounding properties obtain water from the City of Wilson'smunicipal supply network. The site vicinity and surrounding properties are presented in Figure2. Surrounding property owners/occupants are detailed on Table 2.Terraquest reviewed documents submitted to the NCDWM-UST pertaining to the formerrelease incident associated with the Conoco Store No. 33054. In a letter submitted on August25, 2000, Dahl & Associates, Inc. informed the NCDWM-UST that two water supply wellslocated within 250 feet of the release area (727 Ward Blvd. and 1904 Winoca Rd.) had beenproperly abandoned. In doing so, NCDWM-UST Release Incident #10586 was reclassified as aLow Risk and later closed out.As part of the reconnaissance effort, Terraquest also searched for any surface water bodieswithin a 500-foot radius of the site. No surface water bodies are located within 500 feet of thesource area. The nearest surface water body is an unnamed tributary ofWiggins Mill Reservoirlocated approximately 1,650 feet to the southeast.Limited Site Assessment Report-Phase IPrepared by: Terraquest Environmental Consultants, P.C.Report Prepared: 5/25/18Saleh Properties ofWilson, LLCOn The Run - 739 Ward BoulevardWilson, Wilson County, NC
The closest residence is located approximately 290 feet southwest of the release area. Theclosest place of public assembly is the Dollar General store located approximately 200 feet tothe northwest. Land use in the vicinity of the site is primarily commercial/retail along WardBoulevard with residential properties to the east and west. The site and surrounding propertiesalong Ward Boulevard are zoned General Commercial (GC) with residential properties (SR6 &GR6) to the east and west. Zoning classifications of properties within 1,000 feet are indicated inFigure 2.The site is located in the Coastal Plain Physiographic Province. The United State GeologicalSurvey Professional Paper 1401-1, "Hyrdrogeologic Framework of the North Carolina CoastalPlain, Regional Aquifer-System Analysis," indicates the site is underlain by a phreatic aquiferthat is underlain by the Yorktown Confining Unit of the Coastal Plain. Based upon a review ofPlate 7 from the 1401-1 paper (the closest cross-section to the subject property)/ the releasearea does not overlie a recharge area for the Yorktown Aquifer, the shallowest aquifer believedto be underlying the release area since the Yorktown Unit is located at a shallower depthbetween the phreatic aquifer and the Yorktown Aquifer. This site is not located in a wellheadprotection area.Based solely upon the receptor survey, the release incident meets the criteria of a "Low" Riskclassification with a Residential land-use classification. Further discussion of the releaseincident's risk ranking is continued in Section 7.0. The residential classification is due to thepresence of residences within 500 feet of the site. To help in determining the risk classificationof this site, a completed Limited Site Assessment Risk Classification and Land Use Form hasbeen included as Appendix B.Limited Site Assessment Report-Phase IPrepared by: Terraquest Environmental Consultants, P.C.Report Prepared: 5/25/18Saleh Properties ofWilson, LLCOn The Run - 739 Ward BoulevardWilson, Wilson County, NC
4.0 SITE GEOLOGY AND HYDROGEOLOGYThe site lies in the Yorktown Formation of the Coastal Plain physiographic province of NorthCarolina. According to the Geologic Map of North Carolina (Brown, et. al, 1985), the site isunderlain by fossiliferous clay and varying amounts of fine sand.The following lithologies were encountered at the site during the installation of monitoring wellTQMW1:O'-S.O'BGL:Silty Clay (CL)Mostly medium stiff tannish-olive clay, with silt and some fine sand.5.0' -15' BGLSilty Sandy Clay (CL)Mostly soft yellowish-olive clay, with silt and fine sand.Site topography is depicted in Figure 1. The monitoring well location is shown on Figure 3. Awell construction record and boring log are included in Appendix C. The monitoring wellinstallation protocol utilized by Terraquest is detailed in the Technical Methods and StandardProcedures in Appendix A.On April 26, 2018, Terraquest personnel supervised the installation of the Type II groundwatermonitoring well TQMW1 in the vicinity of the repaired product line. The monitoring well wasinstalled using Geoprobe 7822DT advancing solid stem augers, operated by an NC-Licenseddriller. The monitoring well was constructed of 5 feet of 2"-diameter PVC riser attached to 10feet of 2"-diameter PVC screen with a 0.010" slot size for a total depth of 15 feet. Terraquestdeveloped the mQnitoring well to allow for the removal of fine sediment that might clog thescreened portion of the well. The monitoring well was developed following the protocoldetailed in the Technical Methods and Standard Procedures in Appendix A. Monitoring wellconstruction information is included in Table 3.Limited Site Assessment Report-Phase IPrepared by: Terraquest Environmental Consultants, P.C.Report Prepared: 5/25/18Saleh Properties of Wilson, LLCOn The Run - 739 Ward BoulevardWilson, Wilson County, NC
5.0 SOIL INVESTIGATIONOn April 26, 2018, Terraquest supervised the advancement of a soil boring in the monitoringwell TQMW1 location. The soil boring was advanced to 10 feet BGL. Soils from the 3 -5 ft, 57 ft, and 8 - 10 ft BGL intervals were collected into scalable plastic bags, logged for lithology,and screened with a Photoionization Detector (PID). A soil boring log is contained in Appendixc.Results of field screening measurements identified the 3 - 5 ft. BGL interval as exhibiting thegreatest VOC readings. Additionally, soils were logged as being moist beginning at 6 ft. BGL andbecoming saturated at 8.5 ft. BGL. For these reasons the 3 - 5 ft. BGL interval was submittedfor laboratory analysis per EPA Method 8260 and MADEP Method for VPH. The soil sample wascollected in laboratory prepared glassware, labeled, and placed on ice pending shipment to aNC-licensed laboratory.Analytical results of the collected soil sample revealed detections of several petroleum-typecontaminants at concentrations that do not exceed the S-t-G MSCCs. Soil analytical results aresummarized on Table 4. The soil boring and monitoring well location is depicted on Figure 4.The full analytical report is contained in Appendix D.6.0 GROUNDWATER INVESTIGATIONOn April 26, 2018, Terraquest personnel collected a groundwater sample from monitoring wellTQMW1 using the standard sampling protocol detailed in Appendix A. Prior to sampling, themonitoring well was gauged for free product. No measurable amount of free product wasobserved at this time; however a heavy sheen and strong gasoline odor were noted within thesample bailer.Limited Site Assessment Report-Phase IPrepared by: Terraquest Environmental Consultants, P.C.Report Prepared: 5/25/18Saleh Properties ofWilson, LLCOn The Run - 739 Ward BoulevardWilson, Wilson County, NC
The collected groundwater sample was placed in laboratory-prepared sample containers,labeled, packed in ice, and shipped to a North Carolina-certified laboratory for analysis prior tothe expiration of the analytical method's hold time. The groundwater sample was analyzedusing the EPA Methods 6200B, 504.1 targeting EDB, and MADEP Method for VPH. Themonitoring well TQMW1 location is indicated on Figure 4.Analytical results for the groundwater sample collected from monitoring well TQ.MW1 revealeda concentration of benzene that exceeds its GCL. Several other petroleum-type contaminantconcentrations were also reported at levels that exceed the 2L Standard. Analytical results forthe collected groundwater sample are summarized in Table 5 and are presented in Figure 4.The full analytical report is contained in Appendix D.During well installation, Terraquest noted saturated well cuttings contained a heavy sheen andstrong petroleum odor, evidence of potential LNAPL. On May 4, 2018, Terraquest gaugedmonitoring well TQMW1 to see if any measurable accumulation of free product had occurred.When gauged, the well was found to contain 0.18 feet of free product exhibiting characteristicsof fresh gasoline.7.0 CONCLUSIONS AND RECOMMENDATIONSTerraquest has performed Limited Site Assessment activities at the On The Run facilityassociated with a petroleum release from a broken product line. From assessment activities todate, the following cdnclusions/recommendations can be drawn:A prior release (NCDWM-UST Incident No. 10586) was reported on the property on June10, 1993. This release incident was closed on August 31, 2001 and a Notice of ResidualPetroleum was filed with the Wilson County Register of Deeds.Based upon available documentation for the On The Run UST system, a broken pipefitting from the mid-grade LIST product line was identified and replaced in November2013. A release of petroleum has occurred from this location; however, no formalLimited Site Assessment Report-Phase IPrepared by: Terraquest Environmental Consultants, P.C.Report Prepared: 5/25/18Saleh Properties ofWilson, LLCOn The Run - 739 Ward BoulevardWilson, Wilson County, NC7
release reporting documentation has been submitted to the NCDWM-UST Section.• Terraquest personnel completed a receptor survey as part of the Limited SiteAssessment. Through the reconnaissance effort/ Terraquest personnel did not identifyany water supply wells within 1,000 feet of the release. The site and surroundingproperties within a 1,000-foot radius derive their drinking water from the City ofWilson's municipal water supply system. Assessment reports associated with theprevious release incident on the property detailed the abandonment of two watersupply wells within 250 feet of the source area.• Soil analytical results showed no contaminant concentrations that exceed the S-t-GMSCCs.• Analytical results of the groundwater sample collected from monitoring well TQMW1revealed a benzene concentration that exceeds its GCL. Several other contaminantconcentrations were reported at levels that exceed the 2L Standard.• Monitoring well TQMW1 was gauged for free product nine days after the TQMW1sample was collected and 0.18 feet of free product was detected.• Based upon the presence of free product in TQMW1 and absence of potential receptorswithin 1,000 feet, Terraquest recommends the release incident be ranked an"Intermediate" risk. With the presence of residences within 500 feet of the source area,the land-use classification should be classified as "Residential".• Terraquest recommends the completion of a CSA to fully define the extent ofgroundwater contamination along with the installation of several recovery wells for thepurpose of free product delineation and for future AFVR and/or MMPE events.8.0 LIMITATIONSThis report is limited to the investigation of petroleum hydrocarbons and does not imply thatother unforeseen adverse impacts to the environment are not present at the On the Run facilityin Wilson, Wilson County, NC. In addition, subsurface heterogeneities not identified during thecurrent study may influence the migration of groundwater or contaminants in unpredictedways. The limited amount of sampling and testing conducted during this study cannotpractically reveal all subsurface heterogeneities. Furthermore, subsurface conditions,particularly groundwater flow, elevations, and water quality may vary through time.

TECHNICAL METHODS/STANDARD PROCEDURESEquipment DecontaminationAll soil sampling equipment utilized during site assessment activities is decontaminated accordingto standard and accepted protocol. Cleaning solutions range from clean potable water to acidicsolutions or organic solvents depending on the contaminants present at the site. Equipmentutilized at sites, such as hand augers, contaminated with petroleum hydrocarbons, is generallydecontaminated with a low-sudsing detergent such as Luiquinox® and triple rinsed with distilledwater. Larger equipment, such as drill rigs and associated tools, is steam cleaned. Alldecontamination procedures are completed within an established decontamination area which islocated away from the active study area. Frequency of equipment decontamination depends onthe nature of work being performed, but in nocaseisdecontamination performed less frequentlythan once per test (i.e., soil boring, well installation, sample collection, etc.). Equipment blanks arecollected as a quality control measure when required by job specifications.Soil Boring InstallationSoil borings are completed using hand-operated sampling tools, truck-mounted drills, orGeoprobe® drilling rigs depending on the depth of sample collection and other site-specificconditions. Hand operated stainiess-steel bucket augers are utilized to collect soil samples atregular intervals to determine site stratigraphy and to test for the presence of volatile organiccompounds. Samples retrieved from the hand auger are necessarily disturbed duringtheaugeringprocess, but can provide accurate information on soil type and contaminant concentrations whenproperly interpreted. Soil samples from hand augered borings are generally retrieved at one totwo foot intervals.Truck-mounted or Geoprobe® drilling equipment is often utilized when sample retrieval depthsexceed 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 usuallyretrieve soil via a hollow-stem auger/split spoon collection method. Geoprobe® rigs usuallyemploy a Macro-Core® tube retrieval system.Hollow stem augers provide relatively undisturbed 2-foot cores of soil samples. Soil samples aregenerally collected at five foot intervals utilizing standard penetration test procedures as definedby the American Society for Testing and Materials (ASTM) or are pushed to the desired depth usingthe 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. slidehammer falling a distance of 30 inches.A Geoprobe® rig is a hydraulically-powered soil probing machine. The probe utilizes static forceand percussion to advance a small diameter sampling device into the subsurface. The samplingapparatus provides relatively undisturbed 5-foot cores of soil samples. Soil samples are collected
continuously. The Macro-Core® tube contains an inserted poly-vinyl chloride (PVC) liner whichretains the soil sample as the tube is driven into the ground. The Macro-Core® tube isdecontaminated 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 describedaccording to the Unified Soil Classification System. Soil descriptions are recorded on a soilboring log.Soil SamplingSoils to be analyzed by a North Carolina-certified laboratory are prepared according to thespecified analytical method. Initially/ soil samples are removed from the ground using either ahand auger, backhoe bucket, spilt spoon auger, or a Macro-Core® sampling tube. During theremoval, care is taken to keep the disturbance of the soil structure to a minimum to reduce theloss of contaminants. Once removed, the samples are placed in the proper sample container forthe 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 inmethanol-preserved 40 mL vials. Also, one 5-gram allotment of soil is placed into sodiumbisulfate-preserved40mLvials (one 5-gram allotment per vial, 2 vials per sample) for the 8260 lowconcentration method. A 250-mL glass jar of the sampled soil is also collected to provide moisturecontent information. Soils sampled for MADEP EPH, EPA Method 8270 and TPH 5030 and 3550 areplaced in a 250-mL glass jar (for_MADEP EPH analysis an amber jar is required). TPH 5030 samplesare preserved in methanol similar to the 8260 analysis. Field personnel wear new, disposablenitrile gloves during the collection of each sample.The soil samples are labeled with the sample location, sample identification/ date and time ofcollection, and the analytical method. The samples are placed on ice, sent to a laboratory, andanalyzed 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 isplaced in a sealable bag and screened for volatile organic vapors. Head screening procedures aredescribed in the following paragraph.Headspace ScreeningCollected 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. Thesoil samples are then set aside for approximately five minutes so that volatile constituents presentin the sample can reach equilibrium concentrations with headspace gases in the bag. Once asuitable time period has passed, the probe of the sampling instrument, typically an Organic VaporMonitor (OVM) or a Photo lonization Detector (PID), is inserted into the bag and the relativeconcentration of total VOCs is measured and permanently recorded in a field note book. VOC
concentrations are measured using either a Thermo Electron Corp. Innova Series catalytic OVM oran Ion Science PhoCheck PID. Both the OVM and PID instrumentation are periodically calibratedaccording to the manufacturer's recommended procedures.The OVM and PID are qualitative tools employed to detect and estimate the concentration oforganic or hydrocarbon vapors. A thin probe is inserted through a small break in the seal of abagged soil sample. For the OVM, an air sample from the headspaceofthe bag is drawn throughthe probe into an internal chamber where the vapors are catalyzed. The concentration of theVOCs is registered on a digital scale in parts per million (ppm). For the PID, an air sample from theheadspace of the bag is drawn across the face of a lamp causingthe sample to emit photons,thepresence of which are converted into aVOCppm reading that is displayed. Oxygen levels are fieldcalibrated prior to each use. VOC calibration occurs periodically depending upon use by using aspan gas of known concentration in a process recommended by the manufacturer.Well Installation/ConstructionMonitoringwells are installed using hand-operated sampling tools, atruck-mounted drill rig, or aGeoprobe drilling rig depending on the depth of well and other site-specific conditions. Allmonitoring wells are installed according to the requirements of 15A NCAC 2C-Well ConstructionStandards. Specifically, individual monitoring wells are constructed of2-inch diameter, schedule40 PVC casing riser and screen. The screen interval is generally 10 to 15 feet of machine slottedPVC with aslotsizeofO.010". Only flush threaded joints are used. The annulus space around thescreen is filled with washed filter pack No. 2 sand. The filter pack extends one to two feet abovethe top of the screen. A one to two foot-thick bentonite pellet seal is then placed above the filterpack. The remainder of the well annulus is completely filled with a Portland (Type 1/11) cementgrout mixture. A protective outer steel manhole/ locking cap, and concrete pad is installed foreach well.Type II Monitoring Well ConstructionSingle-cased monitoringwells are generally used in delineation of groundwater quality within thesurficial 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 washedfilter pack No. 2 sand. The filter pack extends one to two feet above the top of the screen. A oneto two foot-thick bentonite pellet seal is then placed above the filter pack. The remainder of thewell annulus is completely filled with a Portland (Type 1/11) cement grout mixture. A protectiveouter steel manhole, locking cap, and concrete pad are installed for each well.Type III Monitoring Well ConstructionDouble-cased monitoringwells are used in the delineation of groundwater quality within a deeperportion ofthesurficial aquiferoran additional aquifer (e.g. aquitard, bedrock). Afourtosix-inchouter casing is installed through the surficial aquifer until a sufficient depth or until the deeper
aquifer is encountered. The casing is secured with a Portland-grout collar that is tremmied intothe annular spaced from the bottom of the bore hole to the surface. Once the grout hassufficiently cured, the bore hole is continued through the bottom of the outer casing to a depthapproximately 15 - 20 feet beneath the outer casing. The inner casing is constructed of 2-inchdiameter, schedule 40 PVC casing riser and screen. The screen interval is generally 5 to 10 feet ofmachine slotted PVC with a slot size of 0.010". Only flush threaded joints are used. The annulusspace around the screen is filled with washed filter pack No. 2 sand. The filter pack extends one totwo feet above the top of the screen. A one to two foot-thick bentonite pellet seal is then placedabove the filter pack. The remainder of the well annulus is completely filled with the samePortland grout mixture used in the outer casing. A protective outer steel manhole, locking cap,and concrete pad are installed for each well.Well DevelopmentFollowing installation of each well, surging and pumping or bailing techniques will be used toremove fines from the screened interval. Groundwater is removed from each well until clearwater is retrieved or a noticeable reduction in the amount ofsilt is achieved. Purged groundwateris disposed of in an environmentally safe manner.Groundwater SamplingPetroleum SitesGroundwater samples are collected from temporary or permanent monitoring wells according toestablished 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 ispurged of a minimum of three well-bore volumes prior to sample collection in order to assure thatsampled water is representative of aquifer conditions. In temporary wells, the first water whichmigrates into the open borehole is sampled. Samples from both temporary and permanentmonitoringwells are collected using individually wrapped disposable polyethylene bailers by fieldpersonnel wearing disposable nitrile gloves. Only one well is sampled with a given bailer in orderto prevent sample cross-contamination. During both well purging and sampling, proper protectiveclothing and equipment is used and is dependent upon the type and level of contaminantspresent. Also, field personnel change gloves between different samples to reduce the chance ofcross-contamination. Water samples are transferred from the bailer to laboratory-preparedsampling containers using slow emptying devices to reduce the chance of contamination lossthrough volatilization. Preservatives, such as acids, are provided bythe laboratory in pre-preparedcontainers in which collected samples are placed if in-field preservation is necessary. The samplesare labeled with the project name, project number, sample identification, required analysis, anddate and time of collection. The samples are placed on ice, shipped to a certified laboratory, andanalyzed before the expiration of an analytical method's prescribed holding time. Chain-of-custody documentation is maintained for each sample collected in the field.
Other Groundwater Sampling ProtocolsWhen required by state or federal regulations, low-flow groundwater sampling procedures areinstituted. Groundwater samples collected in low-flow situations are collected using a peristalticpump. A peristaltic pump is a type of positive displacement pump. The fluid is contained within aflexible tube fitted inside a circular pump casing. Arotorwith a number of rollers attached to theexternal circumference compresses the flexible tube. As the rotor turns, the part of tube undercompression closes thus forcing the fluid to be pumped to move through the tube. Groundwaterparameters 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 parameterreadings 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 theparameters have stabilized for three successive readings, stabilization has been achieved. In lieu ofmeasuring all five parameters, a minimum subset would include pH, conductivity/ and turbidity orDO. Three successive readings should be within ± 0.1 for pH, ± 3% for conductivity, and ± 10% forturbidity and DO.Upon parameter stabilization, sampling is initiated. Sampling flow rate is maintained attheestab-lished purge rate or is adjusted slightly to minimize aeration, bubble formation, turbulent filling ofsample bottles, or loss of volatiles due to extended residence time in tubing. The same device usedfor purging is used to collect the groundwater sample. Generally, volatile parameters are sampledfirst. The sequence in which samples for inorganic parameters are collected is not determinedunless filtered (dissolved) samples are collected. Preservatives, such as acids, are provided by thelaboratory in pre-prepared containers in which collected samples are placed ifin-field preservationis necessary. The samples are labeled with the project name, project number, sampleidentification, 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'sprescribed holding time. Chain-of-custody documentation is maintained for each sample collectedin the field.During both well purging and sampling, proper protective clothing and equipment is used and isdependent upon the type and level of contaminants present. Also, field personnel change glovesbetween different monitoring wells or sampling points to reduce the chance of cross-contamination. When multiple monitoring wells or sampling points are sampled, sampling iscompleted beginning with the least contaminated well to the most contaminated well, if it isknown.Stockpile SamplingThe number of composite samples collected from a stockpile or a total quantity of excavated soil isbased upon the cubic yardage. One composite sample is collected for every 100 cubic yards ofcontaminated soil excavated. The volume of a stockpile or total quantity of excavated soil iscalculated by approximating the general geometry of a stockpile or estimating the capacity of the
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 areadvanced 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. Iftruck loads are sampled, an aliquot sample is collected from the hauling trucks at a frequencybased upon the capacity of the hauling trucks.Aliquots are gently mixed into a composite sample by a trained TerraQuest technician. Every effortis made to minimize the loss of contaminants through volatilization. The composited soil samplesare jarred in the appropriate laboratory-prepared containers, labeled with the sample location,sample identification, date of collection, time of collection, the analytical method, and thepreservative. The samples are placed on ice, shipped to a laboratory, and analyzed before theexpiration of an analytical method's prescribed holding time. Chain-of-custody documentation ismaintained for each sample collected in the field.Surface Water SamplingSurface water samples, specifically samples from creeks or streams, are collected from amoving/flowing portion of the creek or stream to ensure that stagnant water is not collected. Fieldpersonnel are careful to collect samples from flowing areas that are not so turbulent as to cause aloss 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 changegloves between different locations to reduce the chance of cross-contamination. Samples arecollected directly from the appropriate creek or stream location and placed into the appropriatelaboratory-prepared containers. Preservatives, such as acids, are provided by the laboratory inpre-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, requiredanalysis, and date and time of collection. The samples are cooled on ice to approximately fourdegrees centigrade, shipped to a certified laboratory, and analyzed before the expiration of ananalytical method's prescribed holding time. Chain-of-custody documentation is maintained foreach sample collected in the field.Potable Well SamplingGroundwater 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 samplecollection, the water is run fora sufficient amount of time to purge the bladder tank and assurethat sampled water is representative of aquifer conditions. Once purged, the flow rate is reducedand samples are placed in the appropriate laboratory prepared containers with the appropriateacid preservatives added if preservation of the sample is necessary. The samples are labeled withthe project name, project number, sample identification, required analysis, and date and time ofcollection. The samples are placed on ice, shipped to a laboratory, and analyzed before theexpiration of an analytical method's prescribed holdingtime. Chain-of-custody documentation ismaintained for each sample collected in the field.
Public Water Supply Line SamplingGroundwater samples from public water supply lines are collected from sampling points, typicallyspigots. To sample the spigot, the flow rate is reduced and samples are placed in the appropriatelaboratory prepared containers. The samples are labeled with the sample location, sampleidentification, date of collection, time of collection, and required analytical method. The samplesare placed on ice, shipped to a laboratory, and analyzed before the expiration of an analyticalmethod's prescribed holding time. Chain-of-custody documentation is maintained for each samplecollected in the field.Air SamplingAir samples are collected with the aide of a manually operated MityVac® pump manufactured byPristech, Inc. The air sampling process begins by connecting a length of rubber hose from theMityVac® pump to the port to be sampled, or by hanging the hose inside of an emissions stack insuch a manner as to ensure no outside air causes dilution. Another length of hose is fixed to theoutlet port of the pump and is connected to a new Tedlar bag. Once the pump is hooked up, avalve on the Tedlar collection bag is opened and air is manually forced into the bag by the pumpingaction of sampling personnel.Field MeasurementsField measurements taken to determine the pH, conductivity, temperature, and dissolved oxygenconcentration of a particular groundwater sample are taken directly after a particular monitoringwell has been adequately purged. This ensures that the groundwater parameter data collected isrepresentative of the aquifer conditions at a given location. Once purging of the monitoringwell iscomplete, the decontaminated probe head and cord of the appropriate unit is lowered into therequired monitoring well. If the depth to water in a specific monitoring well is greater than thelength of cord for a particular unit, a new, disposable bailer is slowly lowered into the appropriatemonitoring well and a representative groundwater sample is retrieved. A slow pouring device isfitted onto the end of the disposable bailer and the sample is slowly poured into a new, disposableplastic cup. Groundwater parameter data are then collected from the groundwater in the cupusing the required unit.For pH, conductivity, and temperature, a Hanna Instruments Model 991300 portable meter isutilized. This unit is periodically calibrated and maintained in accordance with the unit'soperations manual by field personnel. Prior to data collection, the unit is properly decontaminatedto prevent cross-contamination. The unit is decontaminated between each sample. Theprocedure used for sample measurement involves lowering the meter's probe into the new,disposable cup containingthegroundwater sample to be measured and slowly stirringthe probeto force groundwater across the probe's membrane. The measurements displayed by the meterare then recorded.
For dissolved oxygen concentration measurements, a YSI® Model 55 Handheld Dissolved OxygenSystem is utilized. This unit is periodically calibrated and maintained in accordance with the unit'soperations manual by field personnel. Priorto data collection, the unit is properly decontaminatedto prevent cross-contamination. The unit is decontaminated between each sample. Theprocedure used for sample measurement involves adjustingthe unit forthe correct altitude wherethe sampling will take place and adjusting the reported units desired. Once this is done, the unit'sprobe is inserted into the groundwater sample to be measured and the probe is slowly stirred toforce the groundwater across the probe's membrane. The measurements displayed by the unitare 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 fieldpersonnel. Groundwater samples are collected in glass containers for measurement by theinstrument. The glass containers are washed with bottled-water between each measurementcollection. Once the sample is collected and inserted into the instrument, the measurementsdisplayed by the instrument are then recorded.
