B. EXECUTIVE SUMMARY
The Blalock Fina site, located at 3574 NC Highway 55 in Angier, North Carolina (site), is 0.69 acres
(Figure 1). The property is vacant and consists of cleared land. The site formerly contained a
gasoline station and convenience store, which began operation in 1957. The gas station was
reportedly closed in 1989 and the underground storage tanks (USTs) were reportedly pumped dry
and filled with a sand/cement/water slurry. A release from the former on-site UST system was
discovered in February 2001, when laboratory analysis of soil samples collected following the
removal of the USTs revealed the presence of petroleum contaminants. Subsequent environmental
investigations at the site are summarized in the following sections.
The North Carolina Department of Environmental Quality (NCDEQ) filed a Notice of Residual
Petroleum (NRP) for soil and groundwater on December 9, 2016 prior to the sale of the property
between Mr. Blalock and a previous property owner (Mr. Scott Leonard). The NRP was filed with
the Harnett County deed in Book 3462, Page 818-820.
As requested by NCDEQ, Terracon mobilized to the site on February 9 and 10, 2022 to:
n gauge depths to groundwater in monitoring wells;
n measure the potential presence of free product in the wells;
n collect field parameters to assess the effectiveness of the remedial activities performed
in August 2021 that included the injection of RemRx™ Controlled Release Polymer
(CRP) Persulfate into multiple borings (Terracon, 2021); and
n collect samples from fifteen monitoring wells (MW-1, MW-3 through MW-12, RW-1, RW-
2, VEW-1, and VEW-2) for analysis of volatile organic compounds (VOCs) and sulfate.
Based on information obtained during the groundwater monitoring activities, Terracon provides the
following findings and conclusions:

n Shallow groundwater depths in February 2022 ranged from 3.33 to 9.39 feet below top of casing
(bTOC). The apparent direction of surficial groundwater flow was to the southwest.
n Free product thicknesses were not detected in the monitoring wells, nor have not been detected
since May 2012 (in MW-5).
n Benzene; 1,2-dibromoethane (EDB); ethylbenzene; isopropylbenzene; naphthalene;
n-propylbenzene; toluene; 1,3,5-trimethylbenzene; 1,2,4-trimethylbenzene; and/or total xylenes
were detected at concentrations above the 15A North Carolina Administrative Code (NCAC) 2L
Groundwater Quality Standards (2L standards) in wells MW-1, MW-3, MW-5, MW-6, MW-7, RW-1,
RW-2, and VEW-1.
n Petroleum constituents were not detected above the North Carolina Gross Contaminant Levels
(GCLs) during this sampling event. Benzene has historically been detected above the GCL in
MW-3 in January 2012 and in MW-5 in January 2018.
n VOCs were detected above the laboratory reporting limits, but below the 2L standards in MW-4,
MW-10, and VEW-2.
n VOCs were not detected above the laboratory reporting limits in MW-8, MW-9, MW-11, and
MW-12.
n Based on the analytical results of injectant indicators (i.e., sulfate, specific conductivity, and
oxidation-reduction potential [ORP]), local spreading of RemRx™’s CRP Persulfate was indicated
by higher average specific conductivity and ORP compared to the baseline sampling event and
higher sulfate concentrations in monitoring wells located nearer and immediately downgradient of
the injectant borings. Data from future monitoring events will aid in interpreting future trends in field
measurement parameters and analytical results.
n Petroleum constituent concentrations in monitoring wells immediately adjacent to and
downgradient of the remediation area (MW-3, MW-4, MW-5, MW-6, MW-8, VEW-1, and VEW 2)
did not exhibit meaningful reductions in constituent concentrations; therefore, future monitoring
events will be required to assess the success of the selected remedial strategy.
n Groundwater impacts extended off the site to the southwest. The groundwater contaminant plume
appeared to be relatively stable and was generally delineated horizontally with the exception of the
southeastern extent. The contaminant plume was not vertically delineated.
n Seven potable water supply wells have historically been identified within 1,000 feet of the source
area. These wells are located to the north, east, and south of the site and are topographically
cross- to up-gradient in relation to the plume. Active potable wells have not been identified within
500 feet of the source area. Municipal water is reportedly available to the site and properties
located within 1,000 feet of the source area.
n Based on conversations with the current property owner and possible future property owner,
Terracon understands the planned future use of the site is as a residential property. According to
the Interstate Technology and Regulatory Council (ITRC) Petroleum Vapor Intrusion (PVI)

guidance, EDB and 1,2-dichloroethane (1,2-DCA) (historically identified on the site) are precluding
factors for petroleum vapor intrusion assessments. Due to the proposed future use of the site,
additional evaluation of the PVI pathway may be warranted based on the location of the residence
and utility lines on the site. To further evaluate the PVI pathway, Terracon compared groundwater
concentrations to the NCDEQ Division of Waste Management (DWM) Groundwater Vapor
Intrusion Screening Levels (GW-VISLs). Several petroleum constituents detected in on-site
monitoring wells exceeded the GW-VISLs.
C. SITE HISTORY AND CHARACTERIZATION
The purpose of this report is to present the findings of assessment and remediation activities
performed in February 2022 at the Blalock Fina site located at 3574 NC Highway 55 in Angier,
Harnett County, North Carolina. This Quarterly Injection Performance Monitoring Report was
prepared for the site in response to a request by Mr. Mark Petermann with the NCDEQ DWM, State
Lead Program. The Quarterly Injection Performance Monitoring Report was prepared in general
accordance with the 15A NCAC 2L .0115 regulations and the NCDEQ UST Section Assessment
Guidelines and Corrective Action Guidelines for Petroleum and Hazardous Substance UST
Releases / Petroleum Non-UST Releases,dated January 19, 2021, under the supervision of Mr.
Donald R. Malone, a North Carolina registered professional engineer (North Carolina Professional
Engineering License No. 20195).
C.1 Site Setting
The Blalock Fina site is comprised of 0.69 acres and consists of vacant, predominantly cleared
land. The surrounding properties consist of residential properties to the west, south, and east with
agricultural land to the north. The site and surrounding properties are depicted on Figures 2 and 3.
C.2 Release Summary
A petroleum release was discovered in February 2001, when laboratory analysis of soil samples
collected following the removal of the former on-site USTs revealed the presence of petroleum
contaminants (Armstrong Geological & Engineering Services, P.C., 2001). The site reportedly
operated as a gasoline station and convenience store beginning in 1957. The site operated two
1,000-gallon gasoline USTs with a third 550-gallon gasoline UST added to the site in 1958.
Approximately 1,224 tons of contaminated soil was excavated during the UST removal activities in
February 2001. A chronological summary of UST removal and subsequent assessment activities at
the site is discussed in the following subsection of this report.
C.3 Previous Investigations
Investigation activities conducted between 2002 and the present included installation of twelve
monitoring wells, two recovery wells, two vapor extraction wells, water supply well sampling, and a
mobile multi-phase extraction (MMPE) event in 2004. An injection event was conducted in July

2011 that utilized chemical oxidation and oxygen-releasing compounds. The injectate consisted of a
solution of 18% persulfate and 2% PermOx Plus into two separate areas at the site including the
former source area on the north side of NC Highway 55 and a down-gradient area south of NC
Highway 55 (Figure 2). During the injection, vacuum extraction was applied to extraction wells and
monitoring wells to remove contaminant mass, prevent groundwater mounding, and provide
hydraulic control (Force Environmental Service Company, LLC, 2011).
NCDEQ filed an NRP for soil and groundwater on December 9, 2016 prior to the sale of the
property between Mr. Blalock and a new property owner. The NRP is filed with the deed in Book
3462, Page 818-820.
From 2014 to the present, Terracon has conducted groundwater and soil investigations at the site to
monitor the concentrations and extents of petroleum contamination. Due to the lack of plume
delineation to the southeast of MW-3, Terracon installed monitoring well MW-12 in October 2019
(Terracon, 2019). In July and August 2021, Terracon completed a baseline groundwater sampling
event of the monitoring well network prior to a persulfate injection at the site. Between August 23
and 25, 2021, Terracon completed the application of approximately 1,800 pounds of RemRx™ CRP
Persulfate and 900 pounds of instantaneous release persulfate in 18 soil borings up to 18 feet
below land surface to chemically enhance degradation of petroleum contaminants in groundwater
(Figure 3) (Terracon, 2021). RemRx™ CRP Persulfate was utilized to establish in-situ chemical
oxidation of the petroleum hydrocarbons by providing a sustained delivery of oxidizing persulfate
ions (S2O82–) and sulfate radicals (SO4• –). RemRx™ developed the sustained-release process to
reduce the potential for contaminant rebounding. Persulfate and the resulting sulfate radical anions
degrade fuel-related constituents using reduction/oxidation chemistry and do not rely on the
presence of naturally occurring or supplemental microbial bacteria.
In November 2021, Terracon completed the first post-injection groundwater monitoring event after
application of the RemRx™ CRP Persulfate. Local spreading of the CRP Persulfate was indicated
by higher average specific conductivity and ORP compared to the baseline sampling event and
higher sulfate and persulfate concentrations in some of the monitoring wells located nearer and
immediately downgradient of the injectant borings (Terracon, 2022). The results of the injection and
other investigation activities were used to generate a conceptual site model of the current site
conditions (Table 1).
C.4 Water Supply Wells
Terracon performed a receptor survey in October 2019 and identified thirteen water supply wells
within 1,000 feet of the source area. At that time, seven of the thirteen wells appeared to be within
1,000 feet of the source area and serve as active, potable water sources. These wells are generally
situated topographically cross- to up-gradient of the plume. The most proximate potable water
supply well is WSW-5, which is approximately 625 feet east of and cross-gradient to the source
area. Downgradient water supply wells are reportedly either inactive or non-potable. Municipal

water is reportedly available to the site and surrounding properties located within 1,000 feet of the
source area. Results of the water-supply well inventory are presented in Table 2 and well locations
are depicted on Figure 3.
D. ASSESSMENT INFORMATION
Terracon mobilized to the site on February 9 and 10, 2022 to:
n gauge depths to groundwater in monitoring wells;
n measure the potential presence of free product in the wells;
n collect field parameters to assess the effectiveness of the remedial activities performed
in August 2021 that included the injection of RemRx™ Controlled Release Polymer
(CRP) Persulfate into multiple borings (Terracon, 2021); and
n collect samples from fifteen monitoring wells (MW-1, MW-3 through MW-12, RW-1, RW-
2, VEW-1, and VEW-2) for analysis of volatile organic compounds (VOCs) and sulfate.
D.1 Free Product Evaluation
Free product was not detected in the monitoring wells during this assessment.
D.2 Groundwater Sampling Activities
Prior to sample collection, Terracon gauged the depth to groundwater in the monitoring wells.
Current and historical groundwater elevation measurements are in Table 3. Shallow groundwater
depths in February 2022 ranged from 3.33 to 9.39 feet below top of casing (bTOC). The apparent
direction of surficial groundwater flow direction was to the southwest based on the calculated
groundwater elevations. Groundwater elevations from the February 9, 2022 gauging event are
depicted on Figure 4. Copies of field notes and a photographic log are provided in Appendix A.
Prior to sampling, the wells were purged with a peristaltic pump using low flow sampling techniques
(i.e., <200 milliliters per minute) prior to sampling. Field parameters consisting of pH, temperature,
ORP, dissolved oxygen, and specific conductivity were measured at each of the well locations. After
stabilization of pH and specific conductivity, a groundwater sample was collected directly into
laboratory supplied containers at low flow sampling rates.
The groundwater samples were placed in laboratory-supplied glassware, labeled, and stored in an
ice-packed cooler. The samples, along with chain-of-custody documentation, were delivered to
Pace Analytical Services, LLC, in West Columbia, South Carolina for analysis of VOCs by United
States Environmental Protection Agency Method 6200B, including methyl tert-butyl ether, EDB, and
di-isopropyl ether, and sulfate by USEPA Method 9056A.

D.3 Field Groundwater Measurements and Sulfate Analytical Results
The groundwater field parameters measured in the monitoring wells from this event and comparisons
to baseline average measurements (Table 4) are summarized below:
n pH field measurements in the monitoring wells ranged from 4.59 to 6.43 standard units
(s.u.) and were on average 1.1 s.u. lower than the baseline sampling event. This is not
remarkable because of the strong buffering capacity of typical aquifer-matrix soils.
n Specific conductivity measurements in the monitoring wells ranged from 32 to 1,263
microsiemens per centimeter (μS/cm). Specific conductivity is a surrogate for the quantity
of ions present in water; and thus, provides an indicator for the presence of sulfate,
persulfate, and perhaps other naturally-occurring ions that might have been released from
aquifer matrix due to the remedial injections. Conductivity measurements were on average
approximately 110 μS/cm higher than the baseline sampling event and 40 μS/cm higher
than the quarterly monitoring event in November 2021. Several wells very near to remedial
injections (i.e., MW-4, MW-5, RW-2) had significantly higher specific conductivity values as
compared to the baseline event.
n Dissolved oxygen measurements in the monitoring wells ranged from 0.38 to 7.58
milligrams per liter (mg/L) and were on average approximately 0.36 mg/L lower than the
baseline sampling event. Oxygen concentrations can vary from event to event, mainly due
infiltration and recharge from rain events, and likely are not directly related to the remedial
injections.
n ORP measurements in the monitoring wells ranged from -37.9 to 253 millivolts (mV). ORP
is a measure of the activity or strength of a water system to transfer electrons either by
oxidizing processes (increasing and/or positive ORP values) or reducing processes (lower
or negative ORP values). The ORP measurements in February 2022 were on average 150
mV higher than the baseline sampling event and approximately 40 mV higher than the
quarterly monitoring event in November 2021. Therefore, the RemRx CRP Persulfate is
increasing the oxidation potential of the aquifer, especially in wells near to the injection
areas.
Dissolved sulfate can be present naturally in groundwater. Terracon did not collect initial background
sulfate concentrations prior to the remedial injections; however, the average sulfate concentration was
5.03 mg/L in the “background” monitoring wells upgradient or fairly distant from the injection borings
(MW-7, MW-9, MW-10, and MW-12). Therefore, we consider 5 mg/L as a reasonable background
concentration for sulfate at the site.
The RemRx™ CRP Persulfate releases sulfate during the reaction and/or decay the S2O82– and SO4• –
ions. Likewise, some of the microorganisms in groundwater can utilize sulfate as an alternative
electron acceptor to drive anaerobic bio-oxidation of the petroleum hydrocarbons via the sulfate
reduction pathway. The average sulfate concentrations ranged from 233 mg/L in November 2021 to
102 mg/L in February 2022 in “non-background wells” immediately adjacent to and downgradient of the
Blalock Fina

Explore with us 8
RemRx™ CRP Persulfate injection borings (i.e., MW-1 through MW-6, MW-8, RW-1, RW-2, VEW-1,
and VEW-2). Therefore, average sulfate concentrations in these monitoring wells decreased by
approximately 130 mg/L from November 2021 to February 2022, likely due to decay of the
instantaneous release persulfate. The sulfate concentrations in downgradient monitor wells VEW-1 is
less than the background sulfate concentration for the site; however, sulfate concentration in
downgradient monitor wells VEW-2, MW-6, MW-8, and MW-11 remain elevated above background.
D.4 Groundwater Analytical Results
Based on the laboratory analytical reports benzene; EDB; ethylbenzene; isopropylbenzene;
naphthalene; n-propylbenzene; toluene; 1,3,5 trimethylbenzene; 1,2,4-trimethylbenzene; and/or total
xylenes were detected at concentrations above the 2L standards in wells MW-1, MW-3, MW-5, MW-6,
MW-7, RW-1, RW-2, and VEW-1. Petroleum constituents were not detected above the North Carolina
Gross Contaminant Levels (GCLs) during this sampling event. Benzene has historically been detected
above the GCL in MW-3 in January 2012 and in MW-5 in January 2018. VOCs were detected above
the laboratory reporting limits, but below the 2L standards in MW-4, MW-10, and VEW-2. VOCs were
not detected above the laboratory reporting limits in MW-8, MW-9, MW-11, and MW-12. Petroleum
constituents were not present at concentrations above GCLs. Benzene has historically been detected
above the GCL in MW-3 in January 2012 and in MW-5 in January 2018.
Groundwater analytical results are depicted on Figure 5 and summarized on Table 5. Copies of the
laboratory analytical reports are provided in Appendix B.Isoconcentration maps for the five leading
petroleum contaminants (benzene; naphthalene; toluene; 1,2,4-trimethylbenzene; and total xylenes)
are included on Figures 6, 7,8, 9, and 10, respectively. These maps show the contaminant plumes
generally originating from the south-central portion of the site in the source area and migrating to
the west-southwest underneath NC Highway 55 and onto the adjacent southwestern property. It
should be noted that there appears to be a small portion of the plume that extends to MW-7, located
northwest of the source area, possibly due to contaminant migration along a preferential flow
pathway such as underground utilities along NC Highway 55. However, elevated naphthalene
concentrations in this well also could be due to anthropogenic sources of this compound (i.e.,
asphalt pavement).
Terracon evaluated the trends in petroleum constituents in monitoring wells immediately adjacent to
and downgradient of the remediation area (MW-3, MW-4, MW-5, MW-6, MW-8, VEW-1, and
VEW-2). Apparent reductions in constituent concentrations are not yet apparent. Therefore, future
monitoring events will be required to assess the success of the selected remedial strategy.
The groundwater contaminant plume appears to be relatively stable and is generally delineated
horizontally with the exception of the southeastern extent. The extent of groundwater impact is not
vertically delineated. Active potable wells are not located within 500 feet of the source area.

EDB and 1,2-DCA are lead scavenging compounds that have continued to be intermittently
detected at the site above the 2L standard. The historical detections indicate that the fuel type
released at the site was gasoline containing lead scavengers. According to the ITRC PVI guidance,
this fuel type is a precluding factor; therefore, the ITRC screening process using screening
distances cannot be used. Due to the proposed future use of the site, additional evaluation of the
PVI pathway may be warranted based on the location of the residence and utility lines on the site.
To further evaluate the PVI pathway, Terracon compared groundwater concentrations to the
NCDEQ DWM GW-VISLs. Several petroleum constituents detected in on-site monitoring wells
exceeded the GW-VISLs.
E. CONCLUSIONS AND RECOMMENDATIONS
Terracon provides the following findings and conclusions based on the information obtained during
this and prior groundwater monitoring events:
n Shallow groundwater depths in February 2022 ranged from 3.33 to 9.39 feet bTOC. The apparent
direction of surficial groundwater flow was to the southwest.
n Free product was not measured in the monitoring wells. Free product thicknesses have not been
measured in the monitoring wells since May 2012 (MW-5).
n Benzene; EDB; ethylbenzene; isopropylbenzene; naphthalene; n-propylbenzene; toluene;
1,3,5-trimethylbenzene; 1,2,4-trimethylbenzene; and/or total xylenes were detected at
concentrations above the 2L standards in wells MW-1, MW-3, MW-5, MW-6, MW-7, RW-1, RW-2,
and VEW-1.
n Petroleum constituents were not detected above the GCLs during this sampling event. Benzene
has historically been detected above the GCL in MW-3 in January 2012 and in MW-5 in January
2018.
n VOCs were detected above the laboratory reporting limits, but below the 2L standards in MW-4,
MW-10, and VEW-2.
n VOCs were not detected above the laboratory reporting limits in MW-8, MW-9, MW-11, and
MW-12.
n Based on the analytical results of the indicator parameters (i.e., specific conductivity and ORP),
local spreading of RemRx™’s CRP Persulfate was indicated by higher average conductivity and
ORP compared to the baseline sampling event and higher sulfate concentrations in monitoring
wells located nearer to and immediately downgradient of the injectant borings. Additional
monitoring events will aid in interpreting field measurement and analytical trends.
n Petroleum constituent concentrations in monitoring wells immediately adjacent to and
downgradient of the remediation area (MW-3, MW-4, MW-5, MW-6, MW-8, VEW-1, and VEW-2)
did not exhibit meaningful reductions in constituent concentrations; therefore, future monitoring
events will be required to assess the success of the selected remedial strategy.

n Groundwater impacts extend off the site to the southwest. The groundwater contaminant plume
appears to be relatively stable and is generally delineated horizontally with the exception of the
southeastern extent. The contaminant plume is not vertically delineated.
n Seven potable water supply wells have historically been identified within 1,000 feet of the source
area. These wells are located to the north, east, and south of the site and are topographically
cross- to up-gradient in relation to the plume. Active potable wells have not been identified within
500 feet of the source area. Municipal water is reportedly available to the site and properties
located within 1,000 feet of the source area.
n Based on conversations with the current property owner and possible future property owner,
Terracon understands the planned future use of the site is as a residential property. According to
the ITRC PVI guidance, EDB and 1,2-DCA (historically identified on the site) are precluding factors
for petroleum vapor intrusion assessments. Due to the proposed future use of the site, additional
evaluation of the PVI pathway may be warranted based on the location of the residence and utility
lines on the site. To further evaluate the PVI pathway, Terracon compared groundwater
concentrations to the NCDEQ DWM Residential GW-VISLs. Several petroleum constituents
detected in on-site monitoring wells exceeded the GW-VISLs.
Based on the data presented in this Quarterly Injection Performance Monitoring Report, Terracon
recommends the following activities be completed at the site.
n Conduct quarterly measurements of groundwater field parameters (e.g. pH, conductivity, and ORP)
to evaluate the distribution and release of the CRP Persulfate. In addition, semi-annual
groundwater monitoring events should be conducted to evaluate the effectiveness of the CRP
Persulfate in remediating petroleum contaminants in groundwater at the site. Groundwater
samples from the semi-annual monitoring events should be analyzed for VOCs and sulfate to
evaluate the distribution and release of the CRP Persulfate. The next quarterly event should be
conducted in May 2022 and the next semi-annual event should be conducted in August 2022.
n Consider performing a vapor intrusion evaluation consisting of at least two shallow soil vapor
points. This work would be considered once plans for the on-site residential structure have been
finalized and would be contingent upon the proposed location of the house as compared to the
known extents of groundwater impacts at the site.

Is the VI Pathway Complete?
1,224 tons of impacted soil excavated during UST removal in 2001,subsequent soil sampling
indicates residual soil impacts in vadose zone below residential MSCCs
1) MMPE event in 2004
2) Injection of oxidation and oxygen releasing compound in 2011. Post-injection
concentrations generally lower, but several well exhibit increased concentrations and/or
mobilization of NAPL.
3) Application of controlled release polymer persulfate and instantaneous release persulfate in
18 on-site borings (August 2021)
Number within 250 feet None identified
Number within 250-500 feet 1 non-potable (WSW-6) and 1 inactive (WSW-10)
Number within 500-1,000 feet 11 (2 inactive, 2 non-potable, 7 potable)
Not Evaluated
Future structures (site not developed), structures <100 ft from impacts
Vacant; residential structure planned by potential future owner
Concentrations below Residential MSCCs - close without soil use restriction
NAPL and/or >GCLs GCL exceedance in MW-5 (2018)
Water Supply Wells Use restricted on-site through NRP
Topographically down-gradient pond - detections not reported January 2018
VI evaluation recommended prior to property development

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.
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.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
J The identification of the analyte is acceptable; the reported value is an estimate.

Hi Heather,

Thanks for helping with the rate adjustment on these samples.

Also can you please remove the sulfate analysis from FB-01? That sample should only be analyzed for VOCs 6200B.

Thanks,
