2.0 Executive Summary
For the groundwater sampling event conducted on April 4, 2022, the following summary is presented.
2.1 Free Product
Free product was not detected in any sampled monitoring well during the April 4, 2022, sampling event.
Free product was first detected at the site on October 27, 2017, in MW-8, during the completion of dissolved oxygen readings in on-site monitoring wells; however, S&ME did not have equipment on October 27, 2017, to measure the free product thickness. During the monitoring well sampling event on November 14, 2017, free product was measured in monitoring well MW-8 at a thickness of 0.5 feet. On December 28, 2017, free product was measured at a thickness of 0.04 feet in monitoring well MW-8. Free product was not detected in monitoring well MW-8 during the May 2018 sampling event, or during subsequent monitoring well sampling events.
2.2 Groundwater Contaminant Concentrations
The maximum concentrations of dissolved groundwater contaminants detected greater than the applicable site cleanup goals during this sampling event are summarized in the table below, along with the gross contamination levels (GCLs) and applicable site cleanup goals: 15A NCAC 2L .0202 groundwater quality standards (2L Standards). Exceedances of the cleanup goals are indicated in wells MW-1, MW-3, MW-4, MW-8, DW-1, DW-2, and DW-3.

2.3 Current and Historical Extent of Groundwater Contamination
Based on the groundwater monitoring event for the reporting period, the extent of groundwater contamination as defined by portions of the site with dissolved benzene in the shallow aquifer at concentrations greater than the 2L Standards generally appears to be less in each sampling event following energization of the groundwater remediation system. GCL exceedances were not reported for this sampling event.
2.4 Water Supply Well Contaminant Concentrations
Water supply well samples were not collected during this report period.
2.5 Remedial Actions
The subject remediation system is designed to treat groundwater and soil in-situ with air sparge and soil vapor extraction techniques and does not withdraw groundwater. Air sparge wells SPG-2, SPG-3, SPG-4, SPG-6, SPG-8, SPG-9, and SPG-10 treat contaminated groundwater to a depth of approximately 40 feet below ground surface (ft-bgs). Air sparge wells DW-1 and DW-2 treat contaminated groundwater to a depth of approximately 65 and 72 ft-bgs, respectively. The system is comprised of nine air sparge and 11 soil vapor extraction wells. The soil vapor extraction portion of the remediation system was approved for operation and energized on August 11, 2017. The air sparge portion of the remediation system was energized on February 14, 2018.
On January 3, 2020, Ms. Mindy Lepard with the NCDEQ UST Section informed S&ME that the NCDEQ wanted monitoring wells DW-1 and DW-2 converted to air sparge wells prior to further operation of the remediation system. On January 13, 2020, the remediation system turned off. In July 2020, S&ME subcontracted ZAVA Industrial, Inc. to convert monitoring wells DW-1 and DW-2 into air sparge wells and to connect the wells to the existing air sparge manifold via new air hoses. On September 3, 2020, following authorization from the NCDEQ, the air sparge system was re-energized.
2.6 Potential Receptors
A receptor survey was last completed in April 2019. Based on the historical deliverables reviewed in association with the subject incident, nine water supply wells are located within 500 feet of the source area. The nearest downgradient surface water body is a pond located approximately 850 feet south of the release location. Based on the USGS Topographic Map, an intermittent stream flows south from the pond toward an unnamed tributary of Boyds Creek.

3.0 Site History and Characterization
3.1 Property Information
The subject property is located at 2668 Highway 49 North, Burlington, Alamance County, North Carolina and is listed on the Alamance County Geographical Information System (GIS) as being identified by Parcel ID No. 161167. OM Aryan, Inc. owns the property and operates a convenience store at the site. The location of the subject property is depicted on Figure I, Appendix I. Figure 2, Appendix I illustrates site features. Figure 3, Appendix I shows the underground and overhead utilities on the subject property.
3.2 UST Owner and Operator Information
The former owners/operators of these tanks were Edward Bonnel Cobb and Huffman Oil Company. Om Aryan, Inc. purchased the petroleum equipment from Huffman Oil Company in 2009, and currently operates the equipment for retail petroleum sales. Information regarding the former UST systems at the site is summarized in Table 1, Appendix II.
3.3 Site History
In November 2007, a release was discovered on the subject property. The source of the release is believed to be near the gasoline USTs and dispensers near the intersection of Highway 49 and McCray Road. Petroleum impacted soil and groundwater were identified during site assessment activities at the site for a pending property transaction in 2007. Based on field screening data compiled in 1995 by S&ME for Huffman Oil Company, the release at the site may have occurred prior to 1995. S&ME has submitted the following reports associated with the subject incident:
• Site Check – Revised report, dated April 28, 2008;
• Initial Abatement Action report, dated August 8, 2008;
• Phase II Limited Site Assessment report, dated January 13, 2009;
• Comprehensive Site Assessment (CSA) report, dated September 24, 2014;
• Corrective Action Plan (CAP) report, dated December 17, 2015; and
• Pre-Corrective Action Plan report, dated February 16, 2016.
Following approval of the CAP, the soil vapor extraction portion of the remediation system was approved for operation and energized on August 11, 2017. The air sparge portion of the remediation system was energized on February 14, 2018.
3.4 UST Information
The UST system at the site included one 8,000-gallon gasoline UST, one 6,000-gallon gasoline UST, one 4,000-gallon gasoline UST, one 6,000-gallon diesel UST, one 4,000-gallon kerosene UST, and one 8,000-gallon diesel UST that are still in use. Information regarding these USTs is summarized in Table 2, Appendix II.
3.5 Non-UST Information
S&ME is not aware of non-UST, petroleum product spills on the property.

3.6 Description of Release
• Date discovered: November 13, 2007
• Cause and Source (including tank identification number and contents): A petroleum release was documented at the subject site during assessment services performed for Ms. Patel prior to her purchase of the property from Huffman Oil Company in 2007. S&ME completed assessment services for the release for Huffman Oil Company during 2007 and 2008. The release incident was declared eligible for reimbursement from the North Carolina Leaking Petroleum Underground Storage Tank Cleanup Fund (Trust Fund). Based on historical assessment documents, a petroleum release occurred prior to 1995. S&ME performed a limited Phase II sampling event for Huffman Oil Company in 1995, before Huffman Oil Company took ownership of the USTs. High vapor concentrations were observed in the soil near the UST system at that time. A UST system may have been in operation at the site prior to the installation of the current system in 1984; however, S&ME did not identify a prior UST system in the NCDEQ UST database.
3.7 Site Characteristics
• Land Use of Site: The site is currently utilized as an automotive fueling station.
• Land Use of Surrounding Area: The land use of the surrounding area is predominantly residential.
• Topography: The site is approximately 700 feet above the Nation Geodetic Vertical Datum of 1929. Based upon the topographic map reviewed, the area of the subject property slopes predominantly to the northeast. A topographic map of the subject property and surrounding areas is included in Figure I, Appendix I.
• Vegetation/Surface Cover: A landscaped grass areas exist on the western portion of the site at the site and the eastern portions are covered by a mixture of gravel, concrete, and asphalt in addition to the site structures.
• Surface Water: The nearest downgradient surface water body is a pond located approximately 850 feet south of the release location. Based on the USGS Topographic Map, an intermittent stream flows south from the pond toward an unnamed tributary of Boyds Creek
• Wells: Seven water supply wells are located within 500 feet of the source area.
• Buildings: According to the Alamance County GIS website, the site contains an approximately 3,840 square foot structure.
• Depth to and Nature of Bedrock: The subject site is located in the Carolina Slate Belt hydrogeologic province of the Piedmont Physiographic Province of North Carolina. The area is underlain by metamorphic rock as described on the 1982 and 1985 Geologic Maps, North Carolina.

3.8 Owners and Occupants of Adjoining/Nearby Properties and Land Use
Details regarding the adjacent properties are summarized in Table 3, Appendix II. The land use of the surrounding area is mainly residential.
3.9 Receptor and Potential Receptor Information
3.9.1 Water Supply Wells
The last receptor survey conducted by S&ME was in April 2019. To update receptor information, S&ME performed a reconnaissance to look for water supply well structures on properties within 1,500 feet of the gasoline dispensers at the subject site. The locations of suspected well structures were noted. S&ME then updated information for properties with water supply wells by obtaining tax information on individual properties from the Alamance County GIS webpage. Details regarding the water supply wells near the source area, including newly identified water supply wells, are provided in Table 4, Appendix II and the locations of the identified water supply wells are shown on Figure 4, Appendix I.
3.9.2 Public Water Supplies
According to the Alamance County Department of Environmental Health, the Town of Green Level, and the City of Burlington Water System on January 7, 2009, public water is not available along Highway 49 North, north of Green Level in Burlington, North Carolina. The nearest public water line is located near the intersection of Highway 49 and Sandy Cross Road, approximately 1.2 miles south of the property.
3.9.3 Surface Waters
The nearest downgradient surface water body is a pond located approximately 850 feet south of the release location. Based on the USGS Topographic Map, an intermittent stream flows south from the pond toward an unnamed tributary of Boyds Creek.
3.9.4 Wellhead Protection Area
The subject site is not known to be located within a Well Head Protection Area as defined in USC 300h-7(e), based upon a review of the corresponding webpage of the Public Water Supply Section of the Division of Environmental Health.
3.9.5 Deep Aquifers In The Coastal Plain Region
The subject site is not located in the Coastal Plain Physiographic region of North Carolina; therefore, there are no deep aquifers of concern related to this release incident.
3.9.6 Subsurface Structures
No vaults or basements were observed or identified by S&ME on the property. However, the site has a septic system located on the western portion of the subject property.

4.0 Remediation System Operation
In accordance with the approved Correction Action Plan report written by S&ME and dated December 17, 2015, S&ME installed seven air sparge (AS) wells (SPG-2, SPG-3, SPG-4, SPG-6, SPG-8, SPG-9, and SPG-10) and nine soil vapor extraction (SVE) well (SVE-3, SVE-4, SVE-5, SVE-6, SVE-8, SVE-9, SVE-11, SVE-12, and SVE-13) in January 2017. SVE-1 and SVE-2 were previously installed. Underground piping for the remediation system was completed in June 2017. The locations of the remediation wells and the remediation compound are depicted on Figure 2, Appendix I.
The soil vapor extraction portion of the remediation system was approved for operation and energized in August 11, 2017. The air sparge portion of the remediation system was energized on February 14, 2018. On January 3, 2020, Ms. Mindy Lepard with the NCDEQ UST Section informed S&ME that the NCDEQ wanted monitoring wells DW-1 and DW-2 converted to air sparge wells prior to further operation of the remediation system. On January 13, 2020, the remediation system turned off. In July 2020, S&ME subcontracted ZAVA Industrial, Inc. to convert monitoring wells DW-1 and DW-2 into air sparge wells and to connect the wells to the existing air sparge manifold via new air hoses. On September 3, 2020, following authorization from the NCDEQ, the air sparge system was re-energized.
4.1 Remediation System Operational Conditions
During this reporting period, S&ME conducted system maintenance visits on February 22, 2022, March 31, 2022, and May 31, 2022. The air sparge system was programmed to operate air sparge wells SPG-2, SPG-4, and SPG-8 from 12:00 AM to 3:00 AM and SPG-3, SPG-6, SPG-9, SPG-10, DW-1, and DW-2 from 3:00 AM to 11:00 PM.
The air sparge wells operated at flows ranging from 2 to 4 cubic feet per minute (CFM) and pressures ranging from 20 to 70 pounds per square inch (psi).
The soil vapor extraction system is designed to operate all SVE wells continuously.
The remediation systems ran sporadically during the report period. During the three system site visits, the system was not operating upon arrival, and was restarted. After the May 31, 2022, site visit, it was determined that the PLC controller for the system was not operational and had affected the system performance. Replacement of the PLC was approved by NCDEQ, but replacement was not completed until January 2023 because of a delay in equipment delivery.
The field reports for the site visits are included in Appendix III.
4.2 Cleanup Progress Milestone Review
During the preparation of the Corrective Action Plan (CAP), it was not a requirement to develop milestones; therefore, S&ME has developed milestones for the remediation system using groundwater contaminant concentrations since the air sparge system was energized in February 2018. Because of low system performance during the report period, a calculation of remediation progress was not completed.
The information below was included in the previous report for the site, dated January 13, 2022.
Corrective Action Performance Report (January – December 2022) Huff’s North S&ME Project No. 4358-16-060A
February 28, 2023 8
A comparison of the September 2, 2021 contaminant concentrations to the projected milestones established in the Corrective Action Performance Report dated July 16, 2017, approximates that the remediation of the petroleum-impacted groundwater is approximately one year behind the projected cleanup schedule. Based on the actual groundwater contaminant concentrations in the source area (MW-1, MW-4, MW-8, and DW-2) in November 2017 through September 2021, S&ME projects that the contaminant concentrations will be reduced below the 2L Standards in 2024 (approximately 6 years after the remediation system was energized in November 2017. The most recent groundwater sampling data is provided in Table 6, Appendix II. The current and historical groundwater sampling data is provided in Table 7, Appendix II. The projected/actual contaminant concentration are shown in
Table 8, Appendix II and the graphs are included in Appendix IV.
Figures 6 and 7, Appendix I include updated information for the September 2021, sampling event. The cross-section figures used in the Comprehensive Site Assessment (CSA) for the site (S&ME report 1584-12-0637A, dated September 24, 2014), were used as the basis for the figures. Monitoring wells DW-2 and MW-8 are projected onto Cross-Section A-A’. Benzene data from the September 2, 2021 groundwater sampling event is projected on the figures, which show the vertical extent of petroleum impacts to extend vertically beyond monitoring wells DW-1, DW-2 and DW-3. Soil data was not included in the figures, as no soil contaminant data has been obtained at the site since the completion of the CSA.
4.2.1 Contaminant Mass Calculations in Soil and Groundwater
The following summarizes the calculations made to determine the contaminant mass of petroleum in the soil and groundwater.
4.2.1.1 Soil Contamination Data
S&ME has not completed additional soil assessment at the site since completion of the CSA. Copies of the CSA figures and CSA tables, documenting known soil impacts at the site are included in Appendix V.
4.2.1.2 Baseline Petroleum Contaminant Mass Calculation Assumptions
The volume of a release at the site and the date of release, or whether more than one historical release had occurred, was unknown. Historical assessment data, which identified elevated petroleum vapors in the site soil, suggested that petroleum impacts were present in the soil matrix in 1995 when S&ME completed a limited soil assessment at the property.
S&ME, therefore, estimated an initial contaminant release (petroleum) volume based on laboratory data from the CSA. Because the actual release volume and the date of the release(s) are not known, the impact of product weathering and type of product released was not factored into the estimate. S&ME assumed gasoline was the only product released. S&ME also assumed the subsurface at the site is homogeneous, and contaminant concentrations are consistent through the calculated volumes. These assumptions make the calculated volume of product released a broad estimate, but do provide a general baseline to compare remedial activities.
4.2.1.3 Baseline Petroleum Contaminant Mass Calculation
The attached spreadsheets (included in Appendix VI) were used to calculate the initial contaminant volume based on the data included in the CSA. For soil, S&ME used the estimated 56 milligrams per kilogram (mg/kg)
Corrective Action Performance Report (January – December 2022) Huff’s North S&ME Project No. 4358-16-060A
February 28, 2023 9
isoconcentration maps (Figures 4, 5 and 6 in the CSA) to estimate the horizontal extent of petroleum impacts. The actual horizontal extent of impacts is larger than the 56 mg/kg isoconcentration lines; however, this isoconcentration line was used because of the assumed concentration of petroleum compounds through the entire volume (see below). Also, because the UST system was in place at the time of the CSA, the reduced volume of contaminated soil within the 56 mg/kg isoconcentration line (due to the presence of the UST system) is somewhat offset by the larger total volume of petroleum impacted soil. The vertical extent was estimated at depths of 10 feet, 20 feet and 30 feet based on lab data. For each depth interval, a depth of contaminated media of 10 feet was used to get a total depth profile of 30 feet, which is about the depth to groundwater. Using an assumed unit weight of 120 pounds per cubic foot, the estimated volume of contaminated soil was converted to pounds, then kilograms. S&ME then assumed the entire volume of soil contained a contaminant concentration of 970 mg/kg to get a total mass of contaminant. The highest combined MADEP concentration in soil reported at a depth less than 25 feet was 970 mg/kg, as shown in Table 3 in the CSA. This concentration was selected for two reasons: 1) the UST basin was in place at the time the CSA was completed; therefore, soil samples were not collected directly beneath the UST basin (We presume petroleum concentrations in the soil were greater than 970 mg/kg directly beneath the UST basin.), and 2) the 56 mg/kg isoconcentration is a conservative estimate of the total volume of petroleum contamination soil at the time the CSA was completed. Assuming that all the contamination was gasoline, which weighs about 6.3 pounds per gallon, this calculates to about 7,615 gallons of gasoline in the soil matrix.
For groundwater, S&ME used the estimated extent of benzene impacts from May 2018 to estimate the volume of contaminated groundwater. The volume of contaminated groundwater was calculated based on an assumed effective porosity of 0.3, which was used in the CSA to calculate groundwater velocity. Isoconcentration lines for 10,000 micrograms per liter (µg/l), 1,000 µg/l and 1 µg/l were used, along with an estimated depth of contamination at 40 feet. This estimate is based on the approximate depth to groundwater (30 feet +/-) and the top of the casing in well DW-2 (approximately 72 feet below the land surface). For the calculation, an assumption was made that the concentration within the isoconcentration area was consistent. The estimated concentration used for the area within 10,000 µg/l was the average of the highest reported benzene concentration (23,800 µg/l in MW-1) and 10,000 ug/l. The estimated concentration used for the area within 1,000 µg/l was the average of the highest reported benzene concentration (9,410 µg/l in MW-4) and 1,000 µg/l. The estimated concentration for the area within 1 µg/l was 1 µg/l. From this, a calculation of total milligrams of benzene was calculated for the three areas, which was converted to gallons of benzene. EPA documents estimate that gasoline contains approximately 1% of benzene by volume.
Therefore, the total volume of released gasoline in groundwater was estimated to be approximately 2,320 gallons, making the estimated total volume of gasoline released to be 9,935 (7,615+2,320) gallons.
4.2.2 Calculation of Removal Rate by Vapor Emissions
During this reporting period, on February 25, 2022, and March 31, 2022, S&ME collected a sample of the emissions from the soil vapor extraction system using tubing and a personal pump connected to a Tedlar bag. The sample collected from the soil vapor extraction system exhaust was submitted to Pace National, a North Carolina certified laboratory, for analysis using EPA Method 18 for benzene, toluene, ethylbenzene, total xylenes (cumulatively referred to as BTEX), methyl tert-butyl ether (MTBE), and total petroleum hydrocarbons (TPH). The laboratory report for each sample is included in Appendix VII.

February 28, 2023 10
Because of poor system performance, a calculation of removal rates for the remediation system was not calculated. Data collected during this report period will be incorporated into the next Corrective Action Performance Report.
4.3 Dissolved Oxygen
Dissolved oxygen readings were not collected from monitoring wells during the report period. Dissolved oxygen readings will be collected at monitoring wells at the site in 2023, after the remediation system operation meets system performance requirements.
4.4 Volatile Organic Vapors
Volatile organic compound (VOC) concentrations were not measured at monitoring well locations during the report period. VOC concentrations will be measured at monitoring wells during the next monitoring well sampling event.
4.5 Total Gallons of Water Treated During the Period
The subject remediation system treats an indeterminate volume of contaminated groundwater in-situ with air sparge and soil vapor extraction techniques and does not withdraw groundwater. Air sparge wells SPG-2, SPG-3, SPG-4, SPG-6, SPG-8, SPG-9, and SPG-10 treat contaminated groundwater to a depth of approximately 40 feet below ground surface (ft-bgs). Air sparge wells DW-1 and DW-2 treat contaminated groundwater to a depth of approximately 65 and 72 ft-bgs, respectively.
Because of poor system performance, a calculation of the volume of gasoline remaining in the site groundwater was not completed.
4.6 Future Remediation Activities
S&ME will continue air sparge and soil vapor extraction activities. Site maintenance visits will generally be performed on a monthly basis. The next groundwater sampling event is tentatively scheduled for spring 2023. The next Corrective Action Performance Report will be submitted in July 2023.

5.0 Conclusions
During this reporting period, S&ME conducted three system maintenance visits from February 2022 through May 2022. The air sparge and soil vapor extraction systems operated sporadically during this time.
Analytical results for groundwater samples collected from monitoring wells during the April 2022 sampling event indicate multiple dissolved petroleum compounds in the groundwater at concentrations greater than North Carolina groundwater quality standards. Based on laboratory data, the horizontal extent of the dissolved benzene during the April 2022 sampling event continued to decline from that observed in the February 2016 sampling event. No target petroleum compounds were detected in the April 2022 sampling event at concentrations that exceed the GCLs. Soil and groundwater remediation activities should continue until the target cleanup goals are met. Based on the current groundwater quality data, we recommend the continuation of the semi-annual monitoring well sampling activities.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

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
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL 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.
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.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

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
MDL Method Detection Limit.
ND Not detected at the Reporting Limit (or MDL where applicable).
RDL 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.
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
J4 The associated batch QC was outside the established quality control range for accuracy.
