In accordance with North Carolina Department of Environmental Quality (NC DEQ) regulatory reporting requirements, Apex has prepared a Corrective Action Monitoring Report for the subject property located at 2825 Lane Street in Kannapolis, North Carolina. This report includes results of the semi-annual groundwater sampling for the period beginning January 1, 2020 and ending June 30, 2020. The site has been a working supplier of gasoline, diesel, and kerosene since at least 1984 and probably much earlier. From 1966 to 1972 the site was owned by the Humble Oil Company. In 1972 the property owner became Exxon Corporation via a name change. Aerial photographs obtained from Cabarrus County GIS department suggest that the site was a gas station by 1975. It operated as a Starvin Marvin from 1984 and then Speedway America until October 26, 2001, when Pilot Travel Centers, LLC purchased the property. The objective of the Corrective Action Plan (CAP) prepared by Apex, was to maintain groundwater quality conditions at the site below the applicable 2L Standards for benzene and meth tertbutyl ether (MTBE) while aggressively remediating source area groundwater and minor soil contamination. The corrective action approach to achieve the aforementioned goals for groundwater at the site consisted of an engineered air sparging and soil vapor extraction (SVE) system coupled with monitored natural attenuation. Air sparging will be effective to remove the volatile hydrocarbon constituents, including MTBE from the groundwater. SVE will capture volatile organic vapors from the subsurface and provide an increased pressure gradient to enhance the efficacy of the air sparging. The end of active remediation will be determined when asymptotic conditions are reached in dissolved hydrocarbon concentrations in groundwater or when the applicable 2L standards have been achieved, or risk can be reduced. CAP implementation at the site began in April 2012. Prior to CAP implementation seven monitoring wells (MW-11, MW-12, MW-19, MW-21, MW-23, MW-24, and DMW-3) were above the benzene 2L limit of 1.0 micrograms per liter (µg/L). The MTBE 2L limit of 20 µg/L was exceeded in eight monitoring wells (MW-11, MW-14, MW-17, MW-19, MW-21, MW-23, MW-24, and DMW-3) prior to CAP implementation. At the conclusion of 2nd Quarter 2020 CAP implementation there was no measurable free -phase petroleum product at the site and the benzene 2L CAP endpoint was not exceeded in any monitoring wells sampled. Monitoring wells MW-14 and MW-23 exceeded the MTBE 2L CAP endpoint. Average analytical results decreased across the site as compared with previous sampling events. Petroleum compounds have never been detected in any of the area potable water supplies and sentinel wells such as MW-21, MW-22, and MW-25 continue to indicate that the gasoline plume is confined to the original source zone identified and described in both the Comprehensive Site Assessment (CSA) and approved CAP. Mass balance calculations indicate that the mass of MTBE and benzene remaining in the aquifer are approximately 30 grams in groundwater, down from approximately 89 grams at the CA Monitoring Report (Jan. 1 to June 30, 2020) iii July 2, 2020 Pilot # 56 Incident#36096 conclusion of 41h Quarter 2019 monitoring. Apex recommends initiating post -CAP monitoring of the site for the following reasons: • Mass balance calculations of remaining benzene and MTBE at the site show approximately 30 grams of combined MTBE and benzene remain onsite as a result of the incident. Additionally, a mass reduction for MTBE and benzene of 99.95% has been accomplished with the remediation system. • Absence of measurable dissolved -phase petroleum compounds in area water supply wells since source identification in June 2006. • Absence of measurable dissolved -phase petroleum concentrations in sentinel wells, MW-21, MW-22, and MW-25. • Direction of shallow groundwater flow to the North -Northwest, which is cross - gradient from potable water supplies. • Presence of municipally supplied potable water to many of the area businesses and residences. Apex recommends continued system deactivation and an additional groundwater monitoring event in December 2020 to continue observing dissolved -phase trends in groundwater after system activation. Based on December 2020 dissolved -phase analytical results, Apex will make recommendations regarding system reactivation, additional groundwater monitoring events, potential modeling options to remove risk from the area potable supply wells, and/or additional sentinel monitoring wells between the site and potable water supply wells to reduce risk.

In accordance with North Carolina Department of Environmental Quality (NC DEQ) regulatory reporting requirements, Apex has prepared a Corrective Action Monitoring Report for the subject property located at 2825 Lane Street in Kannapolis, North Carolina (Figure 1). This report includes semi-annual groundwater sampling for the period beginning January 1, 2020 and ending June 30, 2020. The remediation system was installed by Apex in accordance with the NC DEQ-approved Corrective Action Plan (CAP) to address the multiple -phase contaminants identified on the subject property. A description of the remediation system design and function is presented in Section 2.0. A site plan depicting pertinent features of the subject site and surrounding area is provided as Figure 2. This report for semi-annual groundwater monitoring at the Pilot #56 facility is being submitted to Ms. Trudy Beverly of NC DEQ, on behalf of Pilot. 2.0 SITE HISTORY AND BACKGROUND The site has been a working supplier of gasoline, diesel, and kerosene since at least 1984 and probably much earlier. From 1966 to 1972 the site was owned by the Humble Oil Company. In 1972 the property owner became Exxon Corporation via a name change. Aerial photographs obtained from Cabarrus County GIS department suggest that the site was a gas station by 1975. It operated as a Starvin Marvin from 1984 and then Speedway America until October 26, 2001, when Pilot Travel Centers, LLC purchased the property. According to records reviewed by Apex, seven underground storage tanks (USTs) were closed by removal in May 1994. The UST Closure Report also documented that two 12,000- gallon USTs were removed from service in 1991. A list of current and historical USTs for the site are provided in Table 1. The report also documented that there were releases associated with both product lines and the southern UST tank basin. The release was assigned incident number 6379 by the North Carolina Department of Environment and Natural Resources (NCDENR). The site was redeveloped and subjected to active remediation. Following 18 months of active remediation, the incident was closed by NCDENR in 1998. Historical release information is provided in Table 2. In April 2006, a contractor mobilized to the site to gauge monitoring wells prior to abandonment on behalf of the responsible party for incident 6379. The contractor reportedly discovered light non -aqueous phase liquid (LNAPL) in RW-8 and MW-9. Follow-up investigation in the tank areas and product lines failed to determine a new source. NCDENR considered the LNAPL to be a new release and assigned incident number 36096. Several phases of assessment have occurred since 2006. A site check on the south side of the facility was performed which focused on soils around the new UST basin and the dispenser lines. A total of 22 soil samples were collected for total petroleum hydrocarbons (TPH) gasoline -range organics (GRO) analysis. Nine of the 22 soil samples were analyzed for TPH CA Monitoring Report (Jan. 1 to June 30, 2020) 1 July 2, 2020 Pilot # 56 Incident#36096 diesel -range organics (DRO) as well. Four soil samples were reported with GRO concentrations above the NCDENR UST action level of 10 milligrams per kilogram (mg/kg) at the time of the investigation. DRO were detected in five of the soil samples above 10 mg/kg. A Phase II Limited Site Assessment was conducted and submitted, and the site was assigned a "High Risk" ranking by NCDENR. On February 20, 2009, NCDENR issued a Notice of Regulatory Requirements requesting a Comprehensive Site Assessment (CSA) for the site. A CSA was prepared for the site in December 2009 that delineated the dissolved -phase groundwater concentrations vertically and horizontally. An additional round of sampling conducted in September 2010 confirmed the previous delineation. The dissolved -phase hydrocarbon plume did not extend beyond the site property line and the detected groundwater analytes did not exceed the gross contaminant levels (GCLs). The site is ranked `high risk' due to the presence of water supply wells located within a 1,000-foot radius of the source area. It is important to note that all the identified supply wells are located hydraulically cross -gradient of the site and over 425 feet from any exceedances of the North Carolina 15A NCAC 2L groundwater standards (2L). Repeated sampling and analysis of the water supply wells have never detected petroleum hydrocarbons in the samples collected since identification of the release in June 2006. Potable water supply well locations and other receptors are identified on Figure 3 corresponding to property owners, land use classifications, and other receptors as documented in Tables 3, 4, and 5, respectively. Furthermore, sentinel wells such as MW-21, MW-22, and MW-25 continue to indicate that the gasoline plume is confined to the original source zone identified and described in both the CSA and approved CAP. Monitoring well locations are depicted on Figure 4. Municipally supplied potable water is available to area residents for connection. Silty sands dominate the lithology at the site. Shallow soil on site is disturbed and very heavily compacted. Bedrock was encountered at approximately 45 ft below land surface (bls) at DMW-2. Shallow groundwater is encountered at approximately 22 ft bls in the developed portion of the site and flows to the north-northwest. Geologic cross -sections prepared during CAP development are included as Appendix A. The product of concern is unleaded gasoline. The two primary analytes of concern are meth tertbutyl ether (MTBE) and benzene. Historically there were other exceedances of the 2L standard, but there were no 2L exceedances in wells without having either benzene or MTBE present above 2L standards. The source area was presumed as south of the building, near MW- 24. At the time of CAP development, the assumed dissolved -phase groundwater contaminant plume across the site was approximately 180 feet long by 90 feet wide and 30 feet deep. Mass balance calculations indicated that the MTBE mass in the aquifer prior to active remediation was approximately 124 kilograms in groundwater. Based on the risk ranking for the site, corrective action objectives (CAOs) listed below were established for each site media by NCDENR. The status of the site in achieving the established CAOs are also noted. According to the North Carolina Administrative Code, (NCAC) 15A 2L .0407 soil must be cleaned up to Maximum Soil Contaminant Concentrations (MSCCs) for soil to groundwater or residential standards, whichever is lower. As documented in the approved CAP, the CAOs for residential soil were achieved prior to CAP CA Monitoring Report (Jan. 1 to June 30, 2020) 2 July 2, 2020 Pilot # 56 Incident#36096 implementation. The remediation design in the CAP addressed the nominal soil impact in the southern area subsurface that remained above soil -to -groundwater standards. According to NCAC 15A 2L .0202, surface water must be remediated to NCAC, 15A 2B standards (2B). The 2B standard for benzene was 70 µg/L. As documented in the approved CAP, the CAOs for surface water at the site were achieved prior to CAP implementation as no measurable surface water impact has been detected at the site. As such, remedial measures for stormwater and surface water treatment were not carried forward in the CAP. According to NCAC 15A 2L .0202, groundwater at the site must be remediated to the applicable 2L Standards which are 1.0 µg/L and 20 µg/L for benzene and MTBE, respectively. The objective of the CAP was to maintain groundwater quality conditions at the site below the applicable 2L Standards for benzene and MTBE while aggressively remediating source area groundwater and minor soil impact. The corrective action approach to achieve the aforementioned goals for groundwater at the site consisted of an engineered air sparging and soil vapor extraction (SVE) system coupled with monitored natural attenuation. Air sparging will be effective to remove the volatile hydrocarbon constituents, including MTBE from the groundwater. SVE will capture volatile organic vapors from the subsurface and provide an increased pressure gradient to enhance the efficacy of the air sparging. The end of active remediation will be determined when asymptotic conditions are reached in dissolved hydrocarbon concentrations in groundwater or when the applicable 2L standards have been achieved, or risk can be reduced. A full description of the remediation system is provided below in Section 3.0. CAP implementation at the site began in April 2012. Prior to CAP implementation seven monitoring wells (MW-11, MW-12, MW-19, MW-21, MW-23, MW-24, and DMW-3) were above the benzene 2L limit of 1.0 µg/L. The MTBE 2L limit of 20 µg/L was exceeded in eight monitoring wells (MW-11, MW-14, MW-17, MW-19, MW-21, MW-23, MW-24, and DMW-3) prior to CAP implementation. On December 12, 2017 Apex met with Department of Transportation (DOT) staff and their consultant to inspect monitoring wells that were proposed for abandonment during a road construction project at the site. As a result of the construction project Apex turned off AS-5 supplying air to MW-18 pending abandonment by others. Additional wells requiring abandonment for the construction project were MW-3 and MW-19. At the conclusion of 4th Quarter 2019 CAP implementation the dissolved -phase endpoint for benzene of 1.0 µg/L was exceeded in monitoring well MW-23. The dissolved -phase endpoint for MTBE of 20 µg/L was exceeded in monitoring wells MW-9, MW-14 and MW-23. Based on 4th Quarter 2019 analytical results of an average MTBE concentration across the site of 20.9 µg/L and an average benzene concentration of 0.62 µg/L, mass balance calculations indicate the mass of MTBE and benzene remaining in the aquifer are less than 90 grams. 3.0 REMEDIATION SYSTEM The SVE and air sparge remediation system at the Pilot #56 facility was successfully activated on April 18, 2012. The SVE system consists of a Roots Universal RAI® 36 blower (replaced February 2017) paired with a ten horsepower Baldor Electric motor. Together the system module is capable of a maximum extraction rate of 195 actual cubic feet per minute CA Monitoring Report (Jan. 1 to June 30, 2020) 3 July 2, 2020 Pilot # 56 Incident#36096 (ACFM) at a vacuum of 12.0 inches of mercury (in Hg). The air sparge system consists of a 15 horsepower "rotary screw" compressor capable of 44-cubic feet per minute (CFM) at 55.0 pounds per square inch (PSI). The complete system is housed in a mobile eight -foot by 16-foot enclosed cargo trailer. The SVE manifold contains three "legs" capable of supplying a vacuum at recovery locations SVE-1 through SVE-3. The remediation system layout with SVE well locations is depicted on Figure 5. An air sparge manifold within the remediation system enclosure includes individual gate valves, pressure gauges, pressure regulators, flow meters, and check valves required to properly regulate air flow to allow for optimum treatment of the identified subsurface petroleum constituents at air sparge points AS-1 through AS-16. Activation activities included transportation of the turn -key system to the site and connection to the sub -gradient infrastructure and separately metered power from other site activities. The remediation system layout with air sparge well locations is depicted on Figure 6. In response to NC DEQ directives dated August 8, 2019, the SVE and air sparge system components were deactivated on August 14, 2019. 4.0 GROUNDWATER MONITORING During this phase, Apex performed a semi-annual groundwater monitoring event to assess water table elevations and current dissolved -phase contaminant levels. Pursuant to the NC DEQ-approved CAP, Apex performed monitoring and sampling at monitoring wells MW-9, MW-11, MW-12, MW-14, MW-17, MW-20, MW-21, MW-22, MW-23, MW-24, MW-25, and DMW-3. On June 2, 2020, Apex used a SolinstTM electronic interface probe to investigate for the presence of free product and to measure groundwater elevations. Free product was not detected in any of the groundwater monitoring wells gauged during this phase. Groundwater elevation data for the gauging event is presented in Table 6. Groundwater flow at the site was determined by the triangulation method of the relative groundwater elevations within the twelve monitoring wells. Figure 7 is a water table gradient map generated from the relative elevations of equilibrated groundwater as measured on June 2, 2020. Relative groundwater elevations based on surveyed top of casing elevations predict shallow groundwater flow is to the north- northwest, which is consistent with previous investigations. Monitoring/recovery/air sparge well locations are depicted on Figures 4, 5, and 6. Shallow groundwater flow direction is depicted on Figures 1, 3, and 7. Per NC DEQ directives, on June 2, 2020, Apex collected groundwater samples from twelve monitoring wells (MW-9, MW-11, MW-12, MW-14, MW-17, MW-20, MW-21, MW-22, MW-23, MW-24, MW-25, and DMW-3). Prior to sampling, Apex purged each well to remove suspended sediment from the water column and to collect samples representative of aquifer conditions. Each well was purged until a minimum of three well volumes had been displaced. Groundwater samples were collected using dedicated, disposable, high -density polyethylene bailers and were transferred directly into the appropriate sample containers immediately upon collection. The samples were stored on ice pending delivery to the laboratory. Disposable, latex gloves were used during all phases of sample collection. Groundwater samples were submitted to Pace National (Pace) in Mount Juliet, Tennessee for volatile organic compound (VOC) analysis via U.S. EPA SW-846 method 6200B. Strict sample security and chain -of -custody documentation were maintained during all phases of transport. Analytical results yielded CA Monitoring Report (Jan. 1 to June 30, 2020) 4 July 2, 2020 Pilot # 56 Incident#36096 petroleum compounds in five of the twelve monitoring wells sampled, with a maximum MTBE concentration 42.3 µg/L in monitoring well MW-14. Benzene was not detected in any monitoring wells above the laboratory method detection limit during this phase. A summary of current groundwater quality data is presented in Table 7. Chain -of -custody documentation and the laboratory Certificates of Analyses are included as Appendix B. Historical groundwater analytical results are provided in Appendix C. The dissolved -phase endpoint for MTBE of 20 µg/L was exceeded in monitoring wells MW-14 and MW-23. Average analytical results decreased as compared with previous sampling events. An isoconcentration map for MTBE is provided as Figure 8. Trend graphs depicting benzene and MTBE concentrations over time as compared to CAP endpoints are provided as Appendix D. Per NC DEQ directives, on June 2, 2020, Apex also collected groundwater samples from six supply wells (5922, 5925, 5927, 5955 Turkey Road and 2847 and 2865 Lane Street). Supply well locations are depicted on Figure 3. A list of property owners for the supply wells and land use classifications are provided as Tables 3 and 4, respectively. The supply well samples were collected from outdoor spigots after being purged for approximately ten minutes. Clean, disposable latex gloves were used during all phases of sample collection. The samples were labeled and stored on ice pending delivery to the laboratory. Supply well samples were submitted to Pace for VOC analysis via U.S. EPA SW-846 method 6200B. Strict sample security and chain -of -custody documentation were maintained during all phases of transport. Petroleum constituents were not detected in any of the supply well samples; however, tetrachloroethene at a concentration of 1.10 µg/L was detected in supply well SW-5922, which was consistent with the previous sampling events. Tetrachloroethene is typically associated with the use of solvents and could be the result of some recent plumbing repairs at the residence. The laboratory Certificate of Analysis and chain -of -custody records are provided as Appendix B. The site is ranked `high risk' due to the presence of water supply wells located within a 1,000-foot radius of the source area. It is important to note that all the identified supply wells are located hydraulically cross -gradient of the site (shallow groundwater flow is to the North/Northwest) and over 425 feet from any exceedances of the North Carolina 15A NCAC 2L groundwater standards (2L). Repeated sampling and analysis of the water supply wells have never detected petroleum hydrocarbons in the samples collected since identification of the release in June 2006. Furthermore, sentinel wells such as MW-21, MW-22, and MW-25 continue to indicate that the gasoline plume is confined to the original source zone identified and described in both the CSA and approved CAP. Mass balance calculations were updated using June 2020 dissolved -phase groundwater analytical results. The source area was presumed as south of the building, near MW-24. At the time of CAP development, the assumed dissolved -phase groundwater contaminant plume across the site was approximately 180 feet long by 90 feet wide and 30 feet deep (486,000 cubic feet). Multiplying by 7.48 gallons per cubic foot equals a total volume of 3.6 million gallons. Using 30% porosity yields 1.1 million gallons of impacted groundwater above the 2L standard. Using 30,000 µg/L and 1,000 µg/L as average concentrations for MTBE and benzene, respectively, mass balance calculations indicated that the MTBE mass in the aquifer was approximately 124 kilograms and the benzene mass was approximately four kilograms prior to CAP Implementation. Based on 2nd Quarter 2020 analytical results of an average MTBE concentration CA Monitoring Report (Jan. 1 to June 30, 2020) 5 July 2, 2020 Pilot # 56 Incident#36096 across the site of 7.3 µg/L and an average benzene concentration of 0.50 µg/L, mass balance calculations indicate the mass of MTBE and benzene remaining in the aquifer are approximately 89 grams. 5.0 CORRECTIVE ACTION MONITORING REPORT SUMMARY Apex has completed CAP monitoring activities associated with the Pilot #56 facility located in Kannapolis, North Carolina for the period beginning January 1, 2020 and ending June 30, 2020. At the conclusion of 2nd Quarter 2020 CAP implementation there was no measurable free -phase petroleum product at the site and the benzene 2L CAP endpoint was not exceeded in any monitoring wells sampled. Monitoring wells MW-14 and MW-23 exceeded the MTBE 2L CAP endpoint. Average analytical results decreased across the site as compared with previous sampling events. Petroleum compounds have never been detected in any of the area potable water supplies and sentinel wells such as MW-21, MW-22, and MW-25 continue to indicate that the gasoline plume is confined to the original source zone identified and described in both the CSA and approved CAP. Mass balance calculations presented in this report indicate that the mass of MTBE and benzene remaining in the aquifer are approximately 30 grams in groundwater, down from less than 90 grams at the conclusion of 4th Quarter 2020 monitoring. Apex recommends initiating post -CAP monitoring of the site for the following reasons: • Mass balance calculations of remaining benzene and MTBE at the site show approximately 30 grams of combined MTBE and benzene remain onsite as a result of the incident. Additionally, a mass reduction for MTBE and benzene of 99.95% has been accomplished with the remediation system. • Absence of measurable dissolved -phase petroleum compounds in area water supply wells since source identification in June 2006. • Absence of measurable dissolved -phase petroleum concentrations in sentinel wells, MW-21, MW-22, and MW-25. • Direction of shallow groundwater flow to the North -Northwest, which is cross - gradient from potable water supplies. • Presence of municipally supplied potable water to many of the area businesses and residences. Apex recommends continued system deactivation and an additional groundwater monitoring event in December 2020 to continue observing dissolved -phase trends in groundwater after system activation. Based on December 2020 dissolved -phase analytical results, Apex will make recommendations regarding system reactivation, additional groundwater monitoring events, potential modeling options to remove risk from the area potable supply wells, and/or additional sentinel monitoring wells between the site and potable water supply wells to reduce risk.

NATIONWIDE. Guide to Reading and Understanding Your Laboratory Report FP1 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, FTC 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 FSS MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). [Cn] RDL Reported Detection Limit. Rec. Recovery. FSr RPD Relative Percent Difference. SDG Sample Delivery Group. Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and 6 QC (S) 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. If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the a Dilution 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. FSC These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal Limits for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. This column provides a letter and/or number designation that corresponds to additional information concerning the result Qualifier 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. 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" Result (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. A brief discussion about the included sample results, including a discussion of any non -conformances to protocol Case Narrative (Cn) 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 This section of the report includes the results of the laboratory quality control analyses required by procedure or Summary (Qc) 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. This is the document created in the field when your samples were initially collected. This is used to verify the time and Sample Chain of date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This Custody (Sc) 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. This section of your report will provide the results of all testing performed on your samples. These results are provided Sample Results (Sr) 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 J1 Surrogate recovery limits have been exceeded; values are outside upper control limits. J4 The associated batch QC was outside the established quality control range for accuracy. J- The associated batch QC was outside the lower control limits; associated data has a potential negative bias.

Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to m c nc. ov Trudy Attached is the most recent monitoring report for Pilot 56. We did find that we had a conversion error in the mass removal calculations and have corrected them for this report. While we are still seeing the same % removal and great efforts there was more mass to begin with thus there is more mass remaining, but we are still 99.95% reduction from our starting point. First phase with no benzene CAP exceedances and only 2 wells with MTBE exceedances. If you still need a hard copy I can get one put in the mail Monday to you without lab data. Otherwise hope you get a long holiday weekend and stay well.
