SITE HISTORY AND CHARACTERIZATION 1.1. UST OWNER AND OPERATOR INFORMATION The abatement action activities described in this report were conducted in association with  NCDEQ under the guidance of the NCDEQ UST Section.  The UST systems were owned and  operated by J. Gwyn Gambill, Inc, which is currently out of business.  NCDEQ arranged for the  removal of those systems under its Abandoned UST Program.    The UST systems removed from the site on March 24, 2020, included two 4,000‐gallon (gal)  gasoline tanks, one 3,000‐gal diesel tank, associated fuel delivery lines and two dispensers.   The canopy, which had been planned to remain onsite, had to be removed in order to remove  all three USTs.  According to information provided by NCDEQ, the USTs were last operated in  2015.    The table below summarizes UST information for all known or identified USTs relating to the  site. See the attached Table B‐1 for additional information regarding the UST systems.    UST ID NO PRODUCT CAPACITY  (GALLONS) DATE  INSTALLED  DATE  REMOVED  RELEASE  DISCOVERED  1 Diesel 3,000 03/03/1977 03/24/2020 No 2 Gasoline 4,000 03/03/1977 03/24/2020 No 3 Gasoline 4,000 03/03/1977 03/24/2020 No   The site is located at 12295 NC‐88, which is a rural and residential area on the northeast side  of Creston in Ashe County, NC (Figure 1).  The property is currently owned by Earnest and  Donna Osborne of Creston NC and is currently operating as the Creston Superette  convenience store, and multiple rental apartments. The former owner Josephine Owens of  Creston NC sold the property to the Osbornes in early 2020.   The site is adjoined to the south by North Fork New River, and to the west, east, and north by  residential properties.  Public water is not available in the area.  Site photographs obtained  during the UST system closure activities are included in Appendix A.      1.2. HISTORICAL & SURROUNDING UST INFORMATION   Based on information provided by NCDEQ in their most recent UST‐10B site inspection report  dated June 18, 2019, the USTs were last operated in 2015.  All of the USTs and fuel delivery  lines were constructed of single wall steel.  Corrosion protection was installed on all three USTs  on August 9, 1991.  According to the UST‐10B site inspection report, leak detection  requirements for the three USTs were met.    1.3. NON-UST INFORMATION Three aboveground storage tanks (ASTs) were present on the site during the UST Closure  event on the eastern side of the Creston Superette.  A kerosene dispenser and associated AST      Creston Superette Facility ID #0‐0‐23990 WR Project No. 02180080.13 UST Closure Report May 2020 Page 2   (AST 1) are located adjacent to the northeast corner of the building.  East of AST 1, a highway  use diesel dispenser and AST (AST 2) are present; this AST is surrounded by secondary  containment. There is also a smaller AST present (AST 3) south of AST 1, on the east side of  the building.  This AST holds fuel oil which is used to heat the apartments on the south side of  the building.   The locations of the ASTs and propane tank exchange storage are shown on  Figure 2.  Photographs of the ASTs are included in Appendix A.      1.4. DESCRIPTION OF ON-SITE TESTING OF SOILS   Samples of temporarily stockpiled soils that were excavated to remove the USTs and  associated fuel lines were field‐screened with a PID and inspected. All of the soils excavated  from the UST tank area that were above the tanks showed indication of containing petroleum  compounds.  Therefore, these excavated soils were not used to backfill the areas where the  USTs were removed. Samples of stockpiled soils were screened with the PID and submitted to  RedLab’s on‐site laboratory for analysis of TPH as gasoline range organics (GRO) and TPH  diesel range organics (DRO) by the Ultraviolet Florescence (UVF) method.  These samples were  identified as Stockpile SP‐1 through SP‐11, and exhibited TPH GRO and/or TPH GRO  concentrations above NCDEQ Action Levels (see RedLab report in Appendix D).  The  petroleum‐impacted soils were loaded into dump trucks, which transported them to a  permitted soil treatment facility operated by AES of NC in Thomasville, NC.  Copies of the  waste disposal manifests are included in Appendix B.    Soil samples obtained from the base of the UST excavations were also submitted to RedLab’s  on‐site laboratory for analysis of TPH GRO and TPH DRO (see RedLab report in Appendix D).   These samples were identified as T1‐1 through T1‐3, T2‐1 through T2‐3, and T3‐1 through  T3‐3.  None of the reported TPH GRO or TPH DRO concentrations for these UST closure soil  samples exceeded NCDEQ Action Levels.    Soil samples obtained from beneath the fuel lines (FL) between the UST pit and the dispenser  island were submitted to RedLab’s on‐site mobile laboratory for analysis of TPH GRO and DRO  by the UVF method.  These samples included: FL‐1 and FL‐2. The results of these analyses are  included in RedLab’s report, which is provided in Appendix D.  Fuel Line Sample FL‐1 at 2 feet  below ground surface (bgs) and Fuel Line Sample FL‐2 at 2 feet bgs exhibited concentrations  of TPH GRO or TPH DRO above current NCDEQ Action Levels and high organic vapor  concentrations according to PID screening, therefore over‐excavation of soils was conducted  to approximately 10 feet bgs. The deeper samples collected at 10 feet bgs did not exhibit TPH  GRO or TPH DRO concentrations above NCDEQ Action Levels. The petroleum‐impacted soil  was excavated for disposal at a permitted soil treatment facility operated by AES of NC in  Thomasville, NC.  Copies of the waste disposal manifests are included in Appendix B.    Soil samples obtained below the three fuel pumps (FP) in the dispenser island were submitted  to RedLab’s on‐site mobile laboratory for analysis of TPH GRO and TPH DRO by the UVF  Method. These samples included Fuel Pump Samples: FP‐1, FP‐2, and FP‐3. The results of  these analyses are included in RedLab’s report, which is provided in Appendix D.  Fuel Pump  Samples FP‐1, FP‐2, and FP‐2 at 2 feet, 5 feet, and 7 feet bgs contained TPH GRO and TPH  DRO at concentrations above the NCDEQ Action Levels, therefore some over‐excavation of  soils was conducted, and the deeper samples collected at approximately 10 feet bgs did not      Creston Superette Facility ID #0‐0‐23990 WR Project No. 02180080.13 UST Closure Report May 2020 Page 3   exhibit TPH GRO or TPH DRO concentrations above NCDEQ Action Levels.  The petroleum‐ impacted soil was excavated for disposal at a permitted soil treatment facility operated by AES  of NC in Thomasville, NC.    Duplicates of the UST closure soil samples and the soil samples obtained in the vicinity of the  fuel lines and fuel pumps were submitted to a fixed laboratory operated by Pace Analytical  Services (Pace) where they were analyzed for TPH GRO and DRO.  The deepest samples from  locations FP‐1, FP‐2, FP‐3, FL‐1, FL‐2, and three sidewall samples of the extent of the  excavation walls, all at approximately 10 feet bgs were submitted to Pace to be analyzed by  compound‐specific petroleum hydrocarbons.  The results of those analyses are summarized in  Table B‐3 and are discussed further in Section 2.4.    1.5. SITE CHARACTERISTICS AND SURROUNDING PROPERTY The site is located in a rural and residential area northeast of the town of Creston located in  the central‐western portion of Ashe County, North Carolina (Figure 1).  The convenience store  building is in use, and multiple inhabited rental apartments comprise the remainder of the  building.  The portions of the property to the north, east, and west of the store building are  covered with asphalt and gravel.  The portion of the property to the south of the building is a  grassy yard adjacent to the North Fork New River.   Site features, structures, UST system  components and AST locations are depicted on Figure 2.      1.6. INITIAL ABATEMENT ACTIONS, ASSESSMENT ACTIVITIES, AND CORRECTIVE ACTIONS No initial abatement, assessment, or corrective action activities have been performed at the  site to date, with the exception of those described herein.  The UST closure assessment  activities conducted during March 24‐26, 2020 are described in Sections 2 and 3 of this report.      1.7. PREPARATIONS FOR UST CLOSURES  WR submitted the required GW/UST‐3 (Notice of Intent: UST Permanent Closure or  Change‐in‐Service) form to the Winston‐Salem Region of the NCDEQ UST Section on  February 24, 2020 (see Appendix E).     Eastern Environmental Management, Inc. (EEM) obtained the requisite permission to  remove the USTs from the Ashe County Fire Marshal prior to and during closure activities  during the week of March 24, 2020.  Approval for UST removals was given following  testing of the oxygen and lower explosive limits of the atmosphere within each tank.      Residual fluids contained in the USTs were removed by EEM using a vacuum tanker truck  prior to UST closure activities.  A combined total of 2,701 gallons of liquids were pumped  from the USTs and associated fuel delivery lines.  These residuals were disposed of at the  EEM, Inc. facility in Rocky Mount, NC.  Appendix B contains a copy of the disposal  manifest.     Soil was removed from above and around each of the USTs to expose the tops of the tanks  and allow for their removals.  Purging of vapors and reduction of oxygen content within  the tanks was accomplished through the use of F‐500 encapsulator fire suppression agent.       Creston Superette Facility ID #0‐0‐23990 WR Project No. 02180080.13 UST Closure Report May 2020 Page 4   Under supervision of the Ashe County Fire Marshal, the O2/LEL levels within each tank  were measured prior to their removal, and extraction of the tanks was not performed prior  to approval by the fire marshal.     Soils that were excavated to remove the USTs and associated fuel lines that did not exhibit  TPH GRO or TPH DRO concentrations in excess of the action level were used to backfill  the excavated areas along with clean fill and crushed stone obtained from local sources.  A  total of 249.92 tons of soil that exhibited obvious signs of petroleum contamination in the  vicinity of the former USTs, fuel lines, and fuel pumps were transported to AES of NC’s soil  treatment facility in Thomasville, NC.  A copy of the soil disposal manifest is contained in  Appendix B.    1.8. UST CLOSURE PROCEDURES   EEM first removed the asphalt and concrete overlying the three USTs to expose fill materials  covering the USTs.  Soils overlying the tanks exhibited petroleum odor, and were screened as  Stockpile samples SP‐1 through SP‐9. For the purposes of tank removals, only those soils  necessary to facilitate the removal of the tanks were excavated from the side and end walls of  the USTs.  Natural soils beneath each of the three USTs did not exhibit petroleum odors or  show signs of contamination by petroleum.  Obvious petroleum odor was noted within the soil  samples obtained in the vicinity of the two fuel lines (FL‐1 and FL‐2) and the former fuel pumps  (FP‐1, FP‐2, and FP‐3).  Each of the USTs was removed from the subsurface of the site after having been cleared for  removal by the Ashe County Fire Marshal.  The two 4,000‐gallon and one 3,000‐gallon USTs  were extracted using a track hoe excavator.  The condition of each tank upon removal from  the subsurface is shown below:   UST ID Volume (gal) Use Condition 1 3,000 Diesel Good.  No obvious holes or pitting.  2 4,000 Gasoline Good.  No obvious holes or pitting.  3 4,000 Gasoline Good.  No obvious holes or pitting.  The three USTs described above were removed from the site on March 25 and 26, 2020.  All  three USTs were transported to EEM’s Facility in Rocky Mount, NC for disposal/destruction.   Receipts for disposal/recycling of the tanks are included in Appendix C. The UST and fuel line  excavation areas are illustrated on Figure 3.     In association with closure of the USTs on March 24‐25, 2020, WR obtained samples of  excavated fill soils that were stockpiled adjacent to the gasoline and diesel UST excavations  and associated fuel lines (see Section 1.4 for sample IDs).  These samples were submitted to  an on‐site mobile laboratory operated by RedLab for analysis of TPH GRO and TPH DRO by  the UVF method.  Analytical results for these samples are discussed in Section 3.  Copies of  the UVF analysis results performed by RedLab are included in Appendix D.  As no obviously impacted soils were identified during the closure of the USTs under the USTs,  no additional soils beyond those necessary to facilitate UST closures were excavated from  under the UST locations.  On‐site PID screening and visual inspection of stockpiled soils  adjacent to the UST excavations indicated the presence of petroleum contamination.   Subsequent on‐site UVF testing of the soils that were above the USTs exhibited TPH GRO      Creston Superette Facility ID #0‐0‐23990 WR Project No. 02180080.13 UST Closure Report May 2020 Page 5   and/or TPH DRO concentrations that exceeded the current NCDEQ UST Section Action  Levels.  Accordingly, the petroleum‐impacted soil was transported off‐site for disposal at a  permitted soil treatment facility operated by AES of NC in Thomasville, NC.  Clean soil fill and  crushed stone obtained from a local source in Boone, NC, were brought to the site for backfill.     1.9. TANK RESIDUALS, UST DISPOSAL Information described in Section 2.1 and 2.2.  Copies of the residual liquids disposal manifests  are included in Appendix B, and the UST disposal manifests are included in Appendix C.   1.10. INITIAL RESPONSE ACTIONS   On‐site laboratory testing of excavated soils beneath the USTs did not identify concentrations  of TPH GRO or TPH DRO that exceeded current NCDEQ UST Action Levels of 50 mg/kg and  100 mg/kg, respectively. The canopy over the fuel pump island had to be removed, as the  western concrete footing for the structure was above the eastern end of UST #2 (see  Photographs in Appendix A), which could not be removed without compromising the structural  integrity of the canopy and thereby creating an unsafe condition.     On‐site laboratory testing of excavated soils in the vicinity of the fuel lines and fuel pumps  identified concentrations of TPH GRO and TPH DRO that exceeded current NCDEQ UST  Action Levels.  Over‐excavation was conducted in the immediate area of the fuel lines and fuel  pumps in an attempt to remove as much contaminated soil as feasible.  Approximately 95.68  tons of soil in the vicinity of the two fuel lines and fuel pumps that exhibited obvious signs of  petroleum contamination were excavated and transported to AES of NC’s soil treatment  facility in Thomasville, NC.  These findings are summarized on the UST‐2A and UST‐61 forms  that are included in Appendix F.      2. SITE INVESTIGATION   2.1. FIELD SCREENING TECHNIQUES   WR physically monitored the excavation of soil by randomly screening the soils as they were  excavated.  The samples were placed in clean, zip‐lock bags and screened with a RAE Systems®  MiniRAE 3000™ PID for the presence of volatile organic vapors typical of petroleum  hydrocarbons. The PID is an industry‐accepted screening device used to detect the presence  of volatile organic vapors for contamination screening and health and safety reasons, but is not  relied upon to determine specific levels of contamination.      2.2. SOIL SAMPLING PROCEDURES   In accordance with NCDEQ guidance for the closure of commercial UST systems, WR obtained  the requisite number of soil samples from less than two feet beneath the former base of each  fuel pump location, and from two feet beneath the former centerline/midpoint of the  registered gasoline and diesel USTs.  Additionally, WR collected native soil samples from less  than two feet beneath the gasoline and diesel fuel delivery lines at a frequency of  approximately every 10 feet of fuel line.       Creston Superette Facility ID #0‐0‐23990 WR Project No. 02180080.13 UST Closure Report May 2020 Page 6     All soil samples were collected either from the bucket of the excavator or through the use of  a properly decontaminated hand auger.  Each sample was field screened, and placed in  laboratory‐prepared containers including chemical preservatives required by laboratory  methods. WR personnel donned clean nitrile sampling gloves for each sample location.   Following collection, samples were placed on ice in a cooler.  In the case of samples analyzed  by RedLab, LLC, samples were hand carried to the on‐site mobile lab that was on site on March  25, 2020.  In the case of samples submitted to Pace, the samples were placed on ice in a cooler  and transported under chain of custody via FedEx to the Pace laboratory facility in Mount  Juliet, Tennessee.    All samples were logged on chain‐of‐custody (COC) documents which included sample  identifications, sample date and times as well as requested analyses.  Copies of the COCs are  included with laboratory reports in Appendix D.      2.3. QUALITY CONTROL MEASURES   Quality control measures were employed during this project and included use of clean  sampling tools, laboratory‐prepared sample bottle kits, calibrated field instruments, donning of  clean sample gloves during each sample collection and preparation effort and a use of third‐ party laboratories for analysis of soil samples obtained in association with completion of this  project.      2.4 INVESTIGATION RESULTS   2.4.1 UST Closures    The analytical results for the 25 soil samples collected as described in Section 3.2 are  summarized in Table B‐3.  The locations where these soil samples were collected are shown  on Figure 3.  None of the soil samples from beneath the three removed USTs exhibited  concentrations of TPH GRO or TPH DRO that exceeded the Action Levels.  Fixed laboratory  analysis of soil samples from the sidewalls and base of the over‐excavated area near the fuel  dispensers identified VOCs, SVOCs, MADEP‐VPH and MADEP‐EPH hydrocarbon fractions at  concentrations in excess of the respective Soil‐to‐Water MSCCs.  These included samples FL‐ 1 and FL‐2 at 10 feet bgs; FP‐1 and FP‐3 at 10 feet bgs; and three sidewall extent samples  NORTH SW, SOUTH SW, and EAST SW at 10 feet bgs (see Table B‐3).  The concentrations of  VOCs and SVOCs in the UST closure soil sample obtained beneath the former fuel pump FP‐ 2 at 10 feet bgs did not exceed MSCCs.     On March 26, 2020, WR prepared and submitted to NCDEQ a UST‐61 Form, which documents  the discovery of petroleum release in the fuel dispenser area.  On March 26, 2020, WR also  prepared and submitted to NCDEQ a UST‐2A Form that documents the removal of the UST  systems from the site (see Appendix F).    2.4.2 Results of Soil Sampling Near Existing ASTs  No soil sampling was conducted near the existing ASTs, as this was beyond the scope of the  approved UST closure sampling work.       Creston Superette Facility ID #0‐0‐23990 WR Project No. 02180080.13 UST Closure Report May 2020 Page 7   3. CONCLUSIONS AND RECOMMENDATIONS   WR completed the removal of two registered commercial gasoline USTs and one registered  commercial diesel fuel UST and their associated fuel lines and dispensers between March 24 and  26, 2020.  Conclusions regarding these UST system closures and the results of laboratory testing  of associated soil samples include the following:     A combined total of 2,701 gallons of residual product and petroleum‐contaminated water was  removed from the USTs and their associated fuel lines prior to their removal.  These liquids  were transported and disposed of at the EEM, Inc. facility in Rocky Mount, NC.   Two gasoline USTs (two 4,000‐gal) and a diesel fuel UST (3,000‐gal) were removed from the  subsurface of the site on March 24 and 25, 2020.  Each UST was found to be in good condition  with no signs of pitting, holes or corrosion on their exterior surfaces.    A total of 249.92 tons of soil exhibiting contamination by petroleum were removed from the  area above the USTs and where the fuel lines and fuel dispensers associated with the UST  systems were located.  Soil samples obtained from the fuel dispenser area exhibited TPH‐GRO  and TPH‐DRO concentrations in excess of the 50 mg/kg (GRO) and 100 mg/kg (DRO) Action  Levels.  These soils were transported to the AES of NC soil treatment facility in Thomasville,  NC.  Because these results constitute a UST system release, WR completed and submitted a  UST‐61 Form to notify NCDEQ via e‐mail and regular mail on March 26, 2020.     RedLab on‐site laboratory testing of soils occurring beneath the three USTs did not identify  concentrations of TPH GRO or TPH DRO that exceeded the current NCDEQ UST Section  Action Levels.  Accordingly, no over‐excavation was conducted in the tank pit.     The closure soil samples associated with the fuel line and fuel pump areas that were over‐ excavated to approximately 10 feet bgs were analyzed by the RedLab on‐site laboratory. The  results of this testing did not identify concentrations of TPH GRO or TPH DRO that exceeded  the current NCDEQ UST Section Action Levels. Therefore, soil samples from these over‐ excavated areas were sent to Pace for analysis by EPA Methods 8260, 8270, and MADEP VPH  and EPH. All eight soil samples submitted to Pace contained detectable concentrations of  petroleum‐related analytes; seven of the samples contained at least one analyte with a  concentration above the Soil‐to‐Water MSCC. Therefore, a release of petroleum is associated  with this former UST system.      We appreciate the opportunity to be of assistance to the NCDEQ‐DWM, UST Section.  Should  you have any questions or comments regarding this report, please contact us at your convenience.    Sincerely,  WithersRavenel   Brian Bellis, P.G.     Laura R. Elliott, P.G.     Project Manager     Project Geologist        FIGURES MDF LRE DRAWN BY: 04/16/2020 02180080.13 1 SUBJECT SITE SCALE:FIGURE NO.: PROJECT NO.:DATE:APPROVED BY: CRESTON SUPERETTE 12295 NC HIGHWAY 88 WESTCRESTON, ASHE COUNTY, NC GENERAL LOCATION MAP 1"=500 ' GRAPHIC SCALE 1 inch = 500 ft. 0 500250 1000 WithersRavenel Engineers | Planners | Surveyors 115 MacKenan Drive | Cary, NC 27511 | t: 919.469.3340 | license #: C-0832www.withersravenel.com NC HIGHWAY 88 WE S T MDFLREDRAWN BY:04/16/202002180080.132SCALE:FIGURE NO.:PROJECT NO.:DATE:APPROVED BY:SITE MAPWithersRavenelEngineers | Planners | Surveyors115 MacKenan Drive | Cary, NC 27511 | t: 919.469.3340 | license #: C-0832 | www.withersravenel.com1"=21 'GRAPHIC SCALE1 inch = 21 ft.0211142CRESTON SUPERETTE12295 NC HIGHWAY 88 WESTCRESTON, ASHE COUNTY, NCTank 1Tank 2 T a n k 3 FP1 FP 2 FP3 AST 1Pro p a n e E x c h a n ge S to r a g eKe ro s e n eDi s pe n s e r& A ST AST 2Hi g hw a y U s eDi e s e l D i s p e n s e r& A STAST 3Dis p .Dis p .

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. MDL (dry)Method Detection Limit. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. J The identification of the analyte is acceptable; the reported value is an estimate. J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Withers & Ravenel Eng. - Standard 02180080.13 L1203371 04/06/20 16:22 64 of 68 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Withers & Ravenel Eng. - Standard 02180080.13 L1203371 04/06/20 16:30 64 of 68 ONE LAB.
