2.0 Executive Summary
For the groundwater sampling event conducted on April 20, 2022, and May 5, 2022, the following summary is
presented.
2.1 Free Product
No free product was measured in the monitoring wells checked during April 20, 2022, and May 5, 2022, sampling
event.
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 applicable site
cleanup goals: 15A NCAC 2L .0202 groundwater quality standards (2L Standard). Exceedances of the cleanup
goals are indicated in wells W-2, W-4, W-5, W-6, and W-9.

2.3 Current and Historical Extent of Groundwater Contamination
Based on the groundwater monitoring event for the reporting period, the lateral extent of groundwater impacts,
as estimated from the horizontal extent of benzene in the groundwater (see Figure 7, Appendix I), appears to
have decreased since the August 2021 sampling event, with an approximate, calculated area of 37,000 square feet
(ft2), compared to the August 2021 extent of 42,000 ft2. Overall dissolved petroleum concentrations in the source
area (W-2 and W-5) are generally decreasing between each subsequent sampling event. Target constituents have
not been reported in vertical extent monitoring well DW-2 since April 2018.

2.4 Water Supply Well Contaminant Concentrations
On May 5, 2022, S&ME collected a water sample from water supply wells at the Store, Cotton, Jones (samples
collected before and after the POE treatment system), Bowman, and Atkins residences. No target analytes were
detected at concentrations that exceed the respective 2L Standards, with the exception of the Jones influent
sample. MTBE and diisopropyl ether were detected in the Jones influent sample at concentrations of 105 µg/L
and 1.4 µg/L, respectively. The Jones effluent sample did not contain target petroleum analyte concentrations
above laboratory reporting limits.
2.5 Remedial Actions
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. Pilot testing performed in 2011
indicated the radius of influence for the air sparge wells was estimated to be 20 feet or greater. The air sparge
wells treat contaminated groundwater to a depth of 30 ft-bgs in the vicinity of AS-1, AS-2, AS-3, and AS-4 and 50
ft-bgs in the vicinity of DW-1. The system is comprised of five air sparge and five soil vapor extraction wells. The
remediation system was approved for operation and energized on December 14, 2015.
During this reporting period, S&ME conducted four system maintenance visits, the air sparge and soil vapor
extraction systems operated approximately 71 and 77 percent of the time, respectively.
A comparison of the Spring 2022 contaminant concentration to the projected milestones established in the
Corrective Action Performance Report dated July 10, 2018, approximates that the remediation of the petroleum-
impacted groundwater is approximately two years behind the projected cleanup schedule. Based on the actual
groundwater contaminant concentration in the source area (W-2 and W-5) and the downgradient monitoring well
(W-6) since the remediation system was energized in December 2015, S&ME projects that the contaminant
concentrations will be reduced below the 2L Standards in 2023 (approximately 8 years of active remediation). This
projection is based on full system operation without down time. Soil and groundwater remediation activities
should continue until the target cleanup goals are met.
2.6 Potential Receptors
A receptor survey was not completed during this sampling event. Based on the historical deliverables reviewed in
association with the subject incident, five active water supply wells (Store, Cotton, Jones, Fogleman, and Bowman)
are located within 500 feet of the source area. North Prong Stinking Quarter Creek is located approximately 800
feet south of the source area and Chocolate Creek is located approximately 700 feet northwest of the source area.
The nearest public water source is located along Liberty Road, approximately 5 miles west of the property.

3.0 Site History and Characterization
The subject property is located at 3901 Alamance Church Road in Liberty, Guilford County, North Carolina and is
listed on the Guilford County Geographical Information System (GIS) as being identified by Parcel Identification
No. (PIN) 0110035. The property is currently developed with a convenience store. The location of the UST site is
depicted on Figure I, Appendix I. Figure 2, Appendix I illustrates site features.
3.1 UST Owner and Operator Information
Huffman Oil Company is the owner of the existing UST system at the property. The Liberty Food Mart is the UST
Operator. Information regarding the existing and former UST systems at the site are summarized in Table 1,
Appendix II. Table 2, Appendix II provides additional information for the existing UST system. Huffman Oil
Company was the owner of the previously removed USTs at the property.
3.2 UST Information
Two previous generations of USTs were located at the property. Information regarding these USTs is summarized
in Table 1, Appendix II. One set of USTs was removed on May 31, 1989. The USTs were removed from a
common basin at the location marked S4 on Figure 2, Appendix I. A second set of USTs included three 2,000-
gallon gasoline UST and one 1,000-gallon diesel UST. The USTs were located at the same location as the current
UST system (see Figure 2, Appendix I). The USTs were permanently closed by removal in June 2005. The current
UST system, consisting of one 6,000-gallon gasoline UST, one 4,000-gallon gasoline UST, and one 2,000-gallon
diesel UST, was installed in the excavation after the excavation was expanded to accommodate the new USTs.
Approximately 243 tons of petroleum-impacted soil was removed prior to the installation of the new USTs.
3.3 Non-UST Information
One kerosene and one used oil AST are located on the subject property. S&ME is not aware of a release
associated with the ASTs.
3.4 Description of Release
• Date discovered: 1988

• Cause and Source (including tank identification number and contents): A petroleum release was
discovered after a fuel dispenser was damaged. The USTs (UST ID 1, 2, and 3; see Table 1, Appendix II)
were removed on May 31, 1989.

• Date discovered: June 2004

• Cause and Source (including tank identification number and contents): Three 2,000-gallon gasoline USTs
and one 1,000-gallon diesel UST were located in a common tank basin (UST ID 001, 002, 003, 004; see
Table 1, Appendix II). An approximate 0.75-inch hole was observed in the bottom of tank 001. No
perforations were observed in tanks 002, 003, and 004.

• Depth to and Nature of Bedrock: The site is located in the Carolina Slate Belt of the Piedmont
Physiographic province. The area is underlain by a felsic intrusive complex (Geologic Map of Region G,
1982) which has been physically and chemically altered to Saprolite.
3.6 Regional and Site Geology and Hydrogeology
3.6.1 Soil and Bedrock
The site is located in the Carolina Slate Belt of the Piedmont Physiographic province. The area is underlain by a
felsic intrusive complex (Geologic Map of Region G, 1982) which has been physically and chemically altered to
saprolite.
3.6.2 Hydrogeology
The depth to groundwater was measured at each monitoring well prior to sampling activities. Based on the depth
to groundwater data collected on September 29, 2017, and well top of casing elevations, the direction of
groundwater flow appears to be generally to the east, which is consistent with the groundwater flow direction
determined by previous monitoring events.

4.0 Remediation System Operation
In accordance with the approved New Technology Cleanup Plan report written by S&ME and dated December 9,
2013, S&ME installed five air sparge wells (AS-1 through AS-4, and DW-1) and five soil vapor extraction (SVE) wells
(SVE-1 through SVE-5) at the subject site in May 2015. Underground piping for the remediation system was
completed in June 2015. The remediation system was offloaded at the site on September 23, 2015. After
updating the system logic, the remediation system was approved for operation and energized on December 14,
2015. The locations of the remediation wells and the remediation compound are depicted on Figure 2, Appendix
I. The field reports are included in Appendix III
4.1 Remediation System Operational Conditions
As detailed previously, during this reporting period, S&ME conducted four system maintenance visits from January
24, 2022, to June 6, 2022. During this reporting period, the air sparge system has been programmed to operate
air sparge wells AS-1, AS-2, and DW-1 from 08:00 AM to 11:00 PM and AS-2 and AS-3 from 00:01 AM to 08:00
AM. As provided in Table 4-1 below, during this reporting period, the air sparge wells operated at a flow of 2
cubic feet per minute (CFM) and pressures ranging from 9 to 16 pounds per square inch (psi). The air sparge
system ran for approximately 71 percent of the designed run time between January 24, 2022, and June 6, 2022.
The downtime of the air sparge system was due to the breaker being tripped, power failures, and low pressure on
the SVE unit. The system is currently running and S&ME is currently evaluating the system to improve run times.

The soil vapor extraction system is designed to operate all SVE wells continuously. From January 24, 2022, to June
6, 2022, the soil vapor extraction system operated at vacuum pressure between 1 and 2 inches of mercury (in Hg).
Volatile organic concentrations (VOCs) were measured periodically from the soil vapor extraction exhaust stack
using a Photoionization Detector (PID) meter. Recorded exhaust VOC concentrations were <1 part per million
(ppm) for each month of this reporting period. The data shows a marked decline in VOC concentrations since the
remediation system was energized in December 2015 (1,489 ppm) and suggests the remediation system is
effectively reducing VOC concentrations in the subsurface. Overall, the soil vapor extraction system operated
approximately 77 percent of the time between January 24, 2022, and June 6, 2022. The downtime of the soil
vapor extraction system was due to the issues associated with power, described above, and low pressure in the
SVE system. The air sparge and soil vapor extraction well construction data is provided in Table 5, Appendix I.

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 December 2015.
A comparison of the Spring 2022 contaminant concentration to the projected milestones established in the
Corrective Action Performance Report dated July 10, 2018, approximates that the remediation of the petroleum-
impacted groundwater is approximately two years behind the projected cleanup schedule. Based on the actual
groundwater contaminant concentration in the source area (W-2, W-5, and W-6) since the remediation system
was energized in December 2015, S&ME projects that the contaminant concentrations will be reduced below the
2L Standards in March 2023 (approximately 7.5 years of active remediation). 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 concentrations are shown in Table 8,
Appendix II and the graphs are included in Appendix IV.
Figures 5, 6 and 7, Appendix I include updated information for the Spring 2022 sampling event. The cross-
section figures dated July 1997 for the site (S&ME project number 1584-95-059), were used as the basis for Figure
5. Benzene data from the Spring 2022 groundwater sampling event is projected on Figures 5 and 7, which show
the estimated horizontal and vertical extent of petroleum impacts, as defined by benzene. Soil data was not
included in the figures, as no soil contaminant data has been obtained at the site since completion of the
Underground Storage Tank Removal report dated August 11, 2005.
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 the completion of the Underground Storage
Tank Removal report dated August 11, 2005. Copies of the figures and tables, documenting known soil impacts
after the UST system was removed in 2005 are included in Appendix V.
4.2.1.2 Baseline Petroleum Contaminant Mass Calculation Assumptions
The volume of petroleum releases at the site and the specific dates of the releases are unknown. Two petroleum
underground storage tanks (USTs) were removed from the area of the site at S4 (see Figure 2) in 1989. Soil and
groundwater data indicated petroleum impacts from the UST system were present in the soil and groundwater. In
June 2005, four USTs were removed from the site in the area of the existing UST basin. Soil excavation activities
were performed to remove petroleum impacted soil and to expand the excavation for the installation of a new
UST system. The excavation was extended to the groundwater. Soil data from sidewall samples collected after the
UST removal indicated petroleum impacts in the soil remaining in the subsurface.

S&ME Project No. Incident No. 3823/30411
October 18, 2022 9
S&ME, therefore, estimated an initial contaminant release (petroleum) volume based on laboratory data from the
Underground Storage Tank Removal report dated August 11, 2005, and the figures dated July 2005, which
estimate the extent of petroleum impacts at the time the USTs were removed in June 2005. 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 does 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 average gasoline total petroleum hydrocarbon
(TPH_GRO) concentration in milligram per kilogram (mg/kg) for the sidewall soil samples collected for the UST
closure. The horizontal extent of petroleum impacts was estimated based on the location of the UST basins. The
estimated horizontal extent of the UST basin was subtracted from the total to estimate the lateral extent of soil
impacts. The vertical extent was estimated to be 9 feet based on historical depth to water measurements. S&ME
assumed the entire volume of petroleum impacted soil contained a TPH-GRO concentration of 6,604 mg/kg to get
a total mass of contaminant. Based on the above assumptions, and an estimated weight for gasoline, about 6.3
pounds per gallon, this calculates to about 1,675 gallons of gasoline in the soil matrix.
For groundwater, S&ME used the estimated extent of benzene impacts from July 1995 to estimate the volume of
contaminated groundwater. The volume of contaminated groundwater was calculated based on an assumed
effective porosity of 0.3. Isoconcentration lines for free product, 1,000 µg/l and 1 µg/l were used, along with an
estimated depth of contamination at 25 feet. This estimate is based on the approximate depth to groundwater
(30 feet +/-) and the top of the casing in well DW-2. For the calculation, an assumption was made that the
concentration within the isoconcentration area was consistent. The estimated concentration used for the area
within the free product plume was 50,000 ug/l. The estimated concentration used for the area within 1,000 µg/l
was 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 1,595 gallons
in groundwater, making the total volume of gasoline released to be 3,270 (1,675+1,595) gallons.
4.3 Vapor Emissions
On February 17, 2022, May 5, 2022, and June 6, 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 Analytical, 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 vapor emissions analytical
results are summarized in Table 9, Appendix II. The laboratory report is included in Appendix VII.

October 18, 2022 10
The laboratory results indicated concentrations of TPH-GRO that ranged from 1.690 µg/m3 to 9,830 µg/m3 during
these reporting periods. Total BTEX concentrations ranged from 3.54% to 13.4% of the TPH concentrations during
this reporting period. Using the emission data, S&ME estimated the total mass recovered by the soil vapor
extraction system during the approximated run time from January 24, 2022, to June 6, 2022. The mass removal
rates are summarized below, and support data is summarized in Table 9, Appendix II:

Benzene Toluene Ethylbenzene Total Xylenes MTBE TPH-GRO
Mass
Recovered (lbs) 0.003 0.047 0.017 0.023 NA 5.65
To calculate the total removal rate, S&ME averaged data from December 2017 to May 2022. As shown in Table
10, the calculation estimates 913.06 pounds of petroleum vapors as TPH-GRO were removed from the subsurface
during the period December 14, 2015, to June 6, 2022, based on laboratory data from exhaust stack emissions and
system run times, via the soil vapor extraction system. Assuming the TPH-GRO calculation is a total measure of
gasoline removed, and gasoline weighs 6.3 pounds per gallon, this calculates to approximately 145 gallons of
gasoline removed. This equates to approximately 4.4 percent of the estimated initial release mass.
4.4 Dissolved Oxygen
Table 11, Appendix II summarizes dissolved oxygen measurements from the groundwater collected at select
monitoring wells. Dissolved oxygen measurements were not recorded during this reporting period on.
Comparison of measurements at monitoring wells suggests an overall increase in the levels of dissolved oxygen in
the shallow aquifer. This change suggests that air is arriving to the shallow aquifer and stripping of volatile
contaminants is likely taking place. This change further indicates additional dissolved oxygen is being supplied to
the site area, providing additional stimulation of contaminant biodegradation.
4.5 Volatile Organic Vapors
VOC measurements were not recorded during this reporting period. Table 11, Appendix II also shows VOC
measurements collected from select monitoring wells using a PID meter. The measurements indicate the
presence of elevated VOC concentrations in the monitoring wells – suggesting that VOCs are being stripped from
the groundwater via remedial actions.
4.6 Total Gallons of Water Treated During the Period
The subject remediation system treats an indeterminate volume of contaminated groundwater in-situ with an air
sparge and soil vapor extraction techniques and does not withdraw groundwater. Pilot testing performed in 2011
indicated the radius of influence for the air sparge wells was estimated to be 20 feet or greater. The air sparge
wells treat contaminated groundwater to a depth of 30 ft-bgs in the vicinity of AS-1, AS-2, AS-3, and AS-4 and 50
ft-bgs in the vicinity of DW-1.

4.7 Future Remediation Activities
S&ME will continue remediation system operations. Site maintenance visits will generally be performed monthly.
The next groundwater sampling event is tentatively scheduled for October 2022. The next Corrective Action
Performance Report will be submitted in January 2023.

5.0 Conclusions
S&ME conducted four system maintenance visits from January 24, 2022, to June 6, 2022, and the air sparge and
soil vapor extraction systems operated approximately 71 and 77 percent of the time, respectively. The downtime
of the air sparge system was due to the breaker being tripped, power failures, and low pressure on the SVE unit.
Soil and groundwater remediation activities should continue until the target cleanup goals are met. The system is
currently running, however, S&ME is evaluating the system to improve run times.
During this reporting period, approximately 5.65 pounds of petroleum vapors as TPH-GRO were removed from
the subsurface, based on laboratory data from exhaust stack emissions and system run times, via the soil vapor
extraction system.
Analytical results for groundwater samples collected from monitoring wells during the April 20, 2022, and May 5,
2022, sampling event indicate multiple dissolved petroleum compounds in the groundwater at concentrations
greater than North Carolina groundwater quality standards. The data indicates a reduction in dissolved petroleum
compounds in the vicinity of the source area (near W-2) when compared with the baseline concentration from
March 2016. Overall, dissolved petroleum compounds have generally decreased since the March 2016 sampling
event.
A comparison of the April and May 2022 contaminant concentration to the projected milestones established in
the Corrective Action Performance Report dated July 10, 2018, approximates that the remediation of the
petroleum-impacted groundwater is approximately two years behind the projected cleanup schedule. This
projected schedule is due to inconsistent system operations, which appear to have been corrected.

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
The remainder of this page intentionally left blank, there are no qualifiers applied to this SDG.
