Atrium Health — Carolinas Medical Center Main Fuel Leak
1130 Blythe Boulevard
Charlotte, Mecklenburg County, North Carolina
S&ME Project No. 214197
2.0 Executive Summary
The subject property is addressed as 1130 Blythe Boulevard in Charlotte, Mecklenburg County, North Carolina.
The property is owned by Charlotte Mecklenburg Hospital Authority D.B.A. Carolinas Medical Center (Atrium
Health) and is occupied by the Central Energy Plant for Atrium Health Carolinas Medical Center Main. S&ME was
retained by Atrium Health (Atrium) to provide on -call environmental consulting services in response to a release
of petroleum products from damaged product lines associated with the underground storage tank (UST) system
involving three commercial, non -regulated 50,000-gallon heating oil/fuel USTs and two non-commercial,
regulated 50,000-gallon fuel oil USTs. The UST system supplies the Carolinas Medical Center on -site Central
Energy Plant's boilers and backup generators.
It is S&ME's understanding that construction activities adjacent to the UST system, may have damaged
underground product lines supplying the on -site Central Energy Plant. Heating fuel oil was observed by Atrium
Health personnel upon exposing the underground piping on April 22, 2021. Atrium Health personnel filed a UST-
61, 24-Hour Release and UST Leak Reporting Form with the North Carolina Department of Environmental Quality
(NCDEQ) on April 23, 2021. Atrium requested S&ME to provide environmental consulting services in general
accordance with NCDEQ Section Guidelines related to the discovered fuel leak beginning on April 27, 2021.
S&ME performed initial abatement activities on an on -call basis for Atrium Health and submitted the findings and
recommendations to NCDEQ in the Initial Abatement Actions report, Atrium Health — Carolinas Medical Center
Main Fuel Leak, dated June 21, 2021. Petroleum impacted soil was over excavated from the product pipeline and
adjacent areas to the extent practical. Based on Non -Hazardous Waste Manifests provided to S&ME by Atrium,
130.69 tons of material were disposed off -site at AES of NC, LLC in Thomasville North Carolina by Atrium
subcontractors. Risk based soil samples collected by S&ME from the bottom and sidewalls of the excavation
indicated multiple target constituents above their respective Soil -to -Water Maximum Soil Contaminant
Concentrations (MSCC) levels. Based on the post -excavation soil sampling and analysis, S&ME recommended a
Phase I Limited Site Assessment (LSA) in accordance with requirements stated in 15A NCAC 02L .0405 be
performed to assess existing groundwater conditions at the subject site.
A Notice of Regulatory Requirements (NORR), dated September 8, 2021, was issued by NCDEQ to Charlotte
Mecklenburg Hospital Authority confirming a LSA shall be performed. The NORR was forwarded to S&ME by
Atrium and LSA activities were performed.
Atrium personnel informed S&ME of an inactive water supply well, presumed to be an irrigation well, located on
hospital property (Parcel ID: 15302327) approximately 600 feet southeast of the petroleum release source area. On
September 10, 2021, S&ME conducted a receptor survey within 1,500 feet of the source area. S&ME did not
identify additional water supply wells within 1,500 feet of the source area. Potable water is supplied to the
properties within 1,500 feet of the subject property by the Charlotte Water. Little Sugar Creek is located
approximately 420 feet east/southeast of the petroleum release source area.

On October 12, 2021, one monitoring well (identified as MWDT-1) was installed on the subject property to assess
for possible soil and groundwater contamination. Due to soft dig excavation performed at the boring location to
an approximate depth of eight -feet below ground surface (ft. bgs) for utility clearance, one soil sample was
collected at ten-ft. bgs. A groundwater sample was collected on October 13, 2021 and submitted for laboratory
analyses. Due to groundwater influence of the ten-ft. bgs soil sample collected on October 12, 2021, S&ME
personnel returned to the site on November 12, 2021, performed a shallow hand auger boring adjacent to
MWDT-01, collected one soil sample from approximately five-ft. bgs, and submitted for laboratory analysis.
No petroleum constituents were detected in the groundwater sample collected from MWDT-01. However,
tetrachloroethene (PCE) was detected at 38.3 micrograms per liter (pg/L) exceeding the corresponding 15A NCAC
02L .0202 groundwater standard (2L Standard) of 0.7 pg/L. PCE is not a constituent typically associated with a fuel
oil release. Historically, PCE was documented along the eastern portion of the UST system in groundwater
sampling performed in association with the Rankin Building leaking underground storage tank (LUST) (LUST
Incident No. 16638) - which was issued a No Further Action (NFA) by the North Carolina Department of
Environmental and Natural Resources (NCDENR) on June 25, 2003 stating soil contamination does not exceed the
Soil to Groundwater Action Levels and groundwater was not contaminated.
Multiple petroleum constituents were detected in the soil sample collected from five-ft. bgs on November 12,
2021. Although some target constituents exceeded their respective Soil -to -Water MSCC levels, no analyzed
compounds exceeded their respective Industrial/Commercial MSCC action levels.
Based on the collected information presented on the Limited Site Assessment Risk Classification and Land Use
Form, S&ME recommends a priority site ranking of "Low Risk". An "Industrial/Commercial" site land use
classification is recommended for the subject site. Based on the data collected and reported herein, it appears this
petroleum incident should be eligible for No Further Action status.

The NCDEQ "Limited Site Assessment Risk Classification and Land Use Form" is included in Appendix IV.
5.0 Monitoring Well Installation
S&ME contacted North Carolina One Call public utility locating service to identify public underground utilities that
were within the proposed work area. Additionally, S&ME contracted a private utility locator to identify private
underground utilities within the proposed work area. A Site -Specific Health and Safety Plan was prepared,
following the requirements of CFR 1910.120 Hazardous Waste Operations and Emergency Response Standard
(HAZWOPER) rule of the protection of workers who are exposed or potentially exposed to hazardous substances.
Due to existing active underground product lines and underground electrical conduits within the source area,
S&ME contracted a soft -dig excavation contractor to perform an excavation approximately one and one-half
times the diameter of augers scheduled to be used for the well installation to a depth of approximately eight-ft.
bgs to "clear" the boring location and ensure underground utilities will not be damaged during the drilling and
well installation.
The scope of services was performed in general accordance with the NCDEQ Division of Waste Management
(DWM) — UST Section Assessment Guidelines: Petroleum and Hazardous Substance UST Releases, Petroleum Non -
UST Releases, January 18, 2021 Version, hereby referred to as the Guidelines.
5.1 Monitoring Well Installation
On September 29, 2021, subcontractors of S&ME performed soft dig excavation services to "clear' the boring
location of potential subsurface utilities. The proposed monitor well location was selected and marked in the field
along the north side of the product line trench adjacent to the petroleum release source location. During soft dig
excavation, loose gravel trench backfill was encountered and the soft dig excavation was terminated and
backfilled. An alternate boring location was selected southeast of the petroleum release source area and soft dig
excavation was performed. The soft dig excavation was performed to an approximate diameter of sixteen inches
and a depth of approximately eight-ft. bgs due to underground electrical conduits along the southern side of the
product piping trench and underground product lines in the vicinity. Atrium personnel observed the soft dig
excavation and confirmed that no utilities were encountered or exposed within the soft dig excavation. The soft

dig excavation was backfilled with soil removed and marked with a wooden stake in preparation of scheduled
drilling and well installation. NOTE: No groundwater or saturated soils were observed within the soft dig
excavation prior to backfilling. Site photos of the original proposed monitor well location and a photo of the
completed soft dig excavation performed at the alternate location are included in Appendix V.
On October 12, 2021, one monitoring well (identified as MWDT-01) was installed within the backfilled soft dig
excavation on the subject property to assess for possible petroleum groundwater contamination. S&ME was
present on the subject property with a North Carolina licensed well driller with Environmental Drilling and Probing
Services, Inc. (EDPS). A 7822DT Geoprobe® drill rig was used with 4.25-inch inside diameter (ID) hollow stem
augers for the installation of the monitoring well. Note that Subsurface Investigation Permit (SIP) No. 70002933
was issued by Mecklenburg County Health Department, Groundwater and Wastewater services prior to initiation
of drilling. A copy of the SIP is included in Appendix VI.
Prior to well installation, a soil boring was advanced using a two and one -quarter inch outside diameter (OD)
Macro -Cores sampler and direct push techniques. During the advancement of the soil boring, soil profiles were
contained in the Macro -Cores sampler's acetate sleeves and observed by S&ME personnel for soil lithology, the
presence of petroleum odors, staining, and evidence of groundwater. It should be noted that due to site
conditions previously discussed, the boring was performed within the backfilled soft dig excavation performed to
approximately eight-ft. bgs that had been backfilled with excavated soils from the soft dig excavation upon
completion. As such, soil backfill was observed to a depth of approximately eight-ft. bgs, where undisturbed,
residual soils were observed. Wet/saturated soils were observed at approximately 12-ft. bgs. Macro -Cores, probe
refusal was encountered at approximately 18-ft. bgs.
The well was installed for the collection of shallow groundwater located above consolidated material at the site.
No drilling within rock/deep aquifer was performed at the monitoring well location. The monitoring well was
installed to a depth of approximately 17.5-ft. bgs and constructed of two-inch diameter schedule 40, flush -thread,
polyvinyl chloride (PVC) pipe installed through the four and one -quarter -inch ID hollow stem augers. The well was
completed with a 2-foot by 2-foot concrete pad and 8-inch flush mount manhole. At the request of Atrium
personnel, the top of the well pad was left approximately three inches above the existing ground surface to allow
for surficial site dressing and backfill for landscaping that will be performed upon completion of site construction.
The approximate location of the monitoring well is depicted in Figure 3, Appendix I. Site photographs of the
monitoring well location is included in Appendix V. The well construction data is summarized in Table 2,
Appendix II and the well construction log is included in Appendix VI.
5.2 Soil Screening Activities
Soil samples were collected from each Macro -Cores sampler acetate sleave at approximate 5-foot intervals. The
soils collected beneath backfilled soils from the soft dig excavation to approximately ten-ft, bgs were placed in a
sealable plastic bag and screened for the presence of volatile organic compounds (VOCs) utilizing a calibrated
organic vapor analyzer with photoionization and flame ionization detecting capabilities (PID / FID). Visibly wet
soils were encountered at approximately 12-ft. bgs.
The measured PID / FID results are included in Table 5-1 below.

6.0 Media Sampling Methodologies
6.1 Groundwater Sampling
On October 13, 2021, prior to groundwater sampling activities, S&ME measured the depth to the water (DTW)
within monitor well MWDT-01 using an electronic water level probe at 6.60 feet below top of casing (BTOC). Note
that the well casing was measured at approximately three inches bgs. The depth to groundwater measurements
at the time of sampling is included in Table 3, Appendix II.
After measuring the DTW, S&ME purged approximately three well volumes from MWDT-01 using a new
disposable polyethylene bailer. After purging, the well was allowed to recharge prior to sample collection. The
groundwater sample was collected, placed directly from the bailer into laboratory provided sample containers,
and placed in a cooler with ice. The groundwater sample was transported by S&ME personnel under chain of
custody procedures to Pace Analytical Services (Pace) in Huntersville, North Carolina. The groundwater sample
was analyzed for volatile organic compounds (VOCs) by Standard Method 602 with xylenes and semi -volatile
organic compounds (SVOCs) (base/neutrals and acids plus 10 largest non -target peaks) by EPA Method 625.1,
volatile petroleum hydrocarbons (VPH), and extractable petroleum hydrocarbons (EPH) by Massachusetts
Department of Environmental Protection (MADEP) methods. The approximate location of MWDT-01 is depicted in
Figure 3, Appendix I.
6.2 Soil Sampling
On October 12, 2021, one soil sample identified as MW-DT-01 (10') was collected at approximately ten-ft. bgs
using a Geoprobe® Macro -Core@ sampler. The sample was split and placed in labeled zip top plastic bags. One
aliquot was immediately placed in a cooler with ice, while the other was allowed time to volatilize and field PID /
FID screenings were performed.
The collected soil sample from the 10-ft. bgs interval was placed into laboratory -supplied sample containers,
placed in a cooler with ice, and delivered by S&ME personnel under chain of custody procedures to Pace to be
analyzed for VOCs by EPA Method 8260, SVOCs by EPA Method 8270, MADEP EPH, and MADEP VPH.
It was later concluded that the 10-ft. bgs sample submitted for laboratory analysis may have been collected below
the groundwater table and sample results may have been influenced by groundwater based on the moisture
content of the soil sample and the measured depth of stabilized groundwater.

On November 12, 2021, S&ME personnel returned to the subject site and collected one soil sample identified as
2021-11-12-5' utilizing a decontaminated stainless -steel hand auger. The sample was collected from
approximately five-ft. bgs, adjacent to monitor well MWDT-01 in soils not disturbed by soft dig excavation or
drilling activities. The sample was split and placed in labeled zip top plastic bags. One aliquot was immediately
placed in a cooler of ice, while the other was allowed time to volatilize and field PID screenings were performed.
The collected soil sample was placed into laboratory -supplied sample containers, placed in a cooler with ice, and
delivered by S&ME personnel under chain of custody procedures to Pace to be analyzed for VOCs by EPA Method
8260, SVOCs by EPA Method 8270, MADEP EPH, and MADEP VPH.
7.0 Laboratory Analytical Results
A qualitative review of the data was performed to verify that the detected concentrations in the laboratory report
were of known quality. A formal, quantitative data validation was not performed. Laboratory -assigned data
qualifiers were evaluated to verify that rejected or unsupportable data were not included in the dataset. Quality
control data provided in the laboratory reports were also reviewed. No rejected or otherwise unacceptable quality
data was reported from the laboratory.
7.1 Groundwater Analytical Results
No target petroleum constituents were detected above laboratory reporting limits. Several tentatively identified
constituents were detected at estimated concentrations between the laboratory Method Detection Limit (MDL)
and laboratory reporting limit in the groundwater sample collected from monitoring well MWDT-01. PCE was
detected at 38.3 pg/L which exceeds the NCDEQ 2L Standard of 0.7 pg/L. A summary of the laboratory analytical
results for the groundwater sample is presented in Table 4, Appendix II and Figure 3, Appendix I. The
laboratory reports are included in Appendix VII.
7.2 Soil Analytical Results
In sample 2021-11-12-5', EPH Aromatic (C11 — C22) was detected at 88.0 mg/kg which exceeds the NCDEQ Soil -
to -Water Maximum Soil Contaminant Concentration (MSCC) of 31 mg/kg. Benzene was detected at 0.074 mg/kg
which exceeds the Soil -to -Water MSCC of 0.0072 mg/kg. p-Isopropyl toluene was detected at 0.56 mg/kg which
exceeds the Soil -to -Water MSCC of 0.12 mg/kg. No other analyzed target compound was detected at
concentrations exceeding the lower NCDEQ UST State Action Levels.
NOTE: PCE was detected in soil sample MW-DT-01(10') at a concentration exceeding the NCDEQ UST State Action
Level of 0.005 mg/kg. It was concluded that this sample may have been collected below the groundwater table
based on percent moisture content (35.4%) of the sample and the measured depth to groundwater (6.60 feet
BTOC). Therefore, sample 2021-11-12-5' was collected and analyzed.
A summary of the laboratory analytical results for the soil samples is presented in Table 5, Appendix II and
Figure 3, Appendix I. The laboratory report is included in Appendix VII.

1130 Blythe Boulevard
Charlotte, Mecklenburg County, North Carolina
S&ME Project No. 214197
8.0 Free Product Investigation and Recovery Report
No free product was encountered during these assessment activities.
9.0 Receptor Information
9.1 Water Supply Well Survey
On September 10, 2021, S&ME conducted a visual water supply well survey. The survey included a visual
reconnaissance by vehicle to observe for the presence of suspected water meters and water well structures for
properties within 1,500 feet of the subject property boundary. During the receptor survey, S&ME did not identify
additional water supply well within 1,500 feet of the source area other than the un-used site well located
approximately 600 feet south of the subject area. Figure 4, Appendix I presents the receptor survey area.
9.2 Public Water Supplies
Based on visual observations of fire hydrants and water meters, in addition to data obtained from Mecklenburg
County GIS information, properties within the within the 1,500-foot search radius surrounding the subject
property likely obtain drinking water from Charlotte Water.
9.3 Surface Water
Little Sugar Creek is located approximately 420 feet to the east of the source area.
9.4 Wellhead Protection Areas
According to a review of the NCDEQ DWR Wellhead Protection Areas website, no Wellhead Protection Areas were
identified on the website's map within 1,500 feet of the release source area.
9.5 Property Use
The subject site is the Central Energy Plant for Atrium Health — Carolinas Medical Center Main, located on the
southern portion of the hospital campus. Active construction is currently being performed for facility expansion to
include medical school and rehabilitation facilities adjacent to the source location.
9.6 Subsurface Structures
Basements were not observed in off -site residential structured structures within 500 feet of the release source
area.
9.7 Property Owners and Occupants

Report of Limited Site Assessment
Atrium Health — Carolinas Medical Center Main Fuel Leak r
1130 Blythe Boulevard
Charlotte, Mecklenburg County, North Carolina -
S&ME Project No. 214197
10.0 Site Geology and Hydrogeology
The site is located within the Charlotte Belt of the Piedmont Physiographic Province of North Carolina. Geologic
mapping by U.S. Geological Survey (USGS) indicates the underlying bedrock consists mostly of igneous rocks such
as granite, diorite, and gabbro.
The Piedmont Province generally consists of well-rounded hills and ridges, which are dissected by a well -
developed system of draws and streams. The Piedmont Province is predominantly underlain by metamorphic rock
(formed by heat, pressure and/or chemical action) and igneous rock (formed directly from molten material), which
were initially formed during the Precambrian and Paleozoic eras. The volcanic and sedimentary rocks deposited in
the Piedmont Province during the Precambrian eras were the host for the metamorphism and were changed to
gneiss and schist. The more recent Paleozoic era had periods of igneous emplacement, with at least several
episodes of regional metamorphism resulting in the majority of the rock types seen today.
Groundwater is recharged by precipitation in the interstream areas. A part of the precipitation infiltrates through
the unsaturated zone to the water table, which normally occurs in saprolite. Groundwater is primarily stored in
void spaces in the saprolite with secondary storage in fractures within the bedrock. The groundwater flow
direction in the saprolite generally trends from topographic highs, or groundwater re -charge areas, toward
topographic lows where surface water bodies represent groundwater discharge points. Based on this general
trend, groundwater flow at the subject site is likely to the southwest.
10.1 Soil
Soils encountered during drilling and/or hand auger activities generally consisted of fill soils field classified as red
tan clayey silty sand and residual soils field classified tan grey sandy silty clay and tan to grey silty fine sand.
10.2 Groundwater
Based on the groundwater measurements collected by S&ME on March 22, 2021 in monitor well MWDT-01,
groundwater in the subject area is approximately six-ft. bgs.
11.0 Conclusion
It is presumed that underground product lines supplying the on -site Central Energy Plant UST system were
damaged by adjacent construction activities. Heating fuel oil was observed by Atrium personnel upon exposing
the underground piping on April 22, 2021. Atrium personnel filed a UST-61, 24-Hour Release and UST Leak
Reporting Form with the NCDEQ on April 23, 2021. Atrium requested S&ME to provide environmental consulting
services in general accordance with NCDEQ Section Guidelines related to the discovered fuel leak beginning on
April 27, 2021.
S&ME performed initial abatement activities on an on -call basis for Atrium Health and submitted the findings and
recommendations to NCDEQ in the Initial Abatement Actions report, Atrium Health — Carolinas Medical Center
Main Fuel Leak, dated June 21, 2021. Petroleum impacted soil was over excavated from the product pipeline and

adjacent areas to the extent practical. Based on Non -Hazardous Waste Manifests provided to S&ME by Atrium,
130.69 tons of material were disposed off -site at AES of NC, LLC in Thomasville, North Carolina by Atrium
subcontractors. Risk based soil samples collected by S&ME from the bottom and sidewalls of the excavation
indicated multiple target constituents above their respective Soil -to -Water MSCC levels. Based on the post -
excavation soil sampling and analysis, S&ME recommended a Phase I LSA in accordance with requirements stated
in 15A NCAC 02L .0405 be performed to assess existing groundwater conditions at the subject site.
A NORR, dated September 8, 2021, was issued by NCDEQ to Charlotte Mecklenburg Hospital Authority confirming
a LSA be performed. The NORR was forwarded to S&ME by Atrium and LSA activities were performed.
Atrium personnel informed S&ME of an inactive water supply well, presumed to be an irrigation well, located on
Atrium Health Carolinas Medical Center Main property (PID 15302327) approximately 600 feet southeast of the
source area. On September 10, 2021, S&ME conducted a receptor survey and did not identify additional water
supply wells within 1,500 feet of the source area. Potable water is supplied to the properties within 1,500 feet of
the subject property by the Charlotte Water. A surface water body, Little Sugar Creek, is located approximately
420 feet east/southeast of the source area.
On October 12, 2021, one monitoring well (identified as MWDT-1) was installed on the subject property to assess
for possible soil and groundwater contamination. Due to soft dig excavation performed at the boring location to
an approximate depth of eight -feet below ground surface (ft. bgs) for utility clearance, one soil sample was
collected at ten-ft. bgs. A groundwater sample was collected on October 13, 2021 and submitted for laboratory
analyses. Due to groundwater influence of the ten-ft. bgs soil sample collected on October 12, 2021, S&ME
personnel returned to the site on November 12, 2021, performed a shallow hand auger boring adjacent to
MWDT-01, collected one soil sample from approximately five-ft. bgs, and submitted for laboratory analysis.
No petroleum constituents were detected in the groundwater sample collected from MWDT-01. However, PCE
was detected at 38.3 micrograms per liter (pg/L) exceeding the corresponding 2L Standard of 0.7 pg/L. PCE is not
a constituent typically associated with a fuel oil release. Historically, PCE was previously documented along the
eastern portion of the UST system associated with the Rankin Building LUST Incident No. 16638 - which was
issued a NFA by NCDEQ (formerly known as NCDENR) on June 25, 2003 stating soil contamination does not
exceed the Soil to Groundwater Action Levels and groundwater was not contaminated.
Multiple petroleum constituents were detected in the soil sample collected from five-ft. bgs on November 12,
2021. Although some target constituents exceeded their respective Soil -to -Water MSCC levels, no analyzed
compounds exceeded their respective Industrial/Commercial MSCC action levels.
Based on the collected information presented on the Limited Site Assessment Risk Classification and Land Use
Form, S&ME recommends a priority site ranking of "Low Risk". An "Industrial/Commercial" site land use
classification is recommended for the subject site. Based on the data collected and reported herein, it appears the
incident could be eligible for No Further Action status.

Project: ATRIUM FUEL LEAK
Pace Project No.: 92566994
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.

Pace Project No.: 92567131
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.

QUALIFIERS
Project: ATRIUM FUEL LEAK
Pace Project No.: 92572345
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.
ANALYTE QUALIFIERS
IK The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should
be considered an estimated value.
IL This analyte exceeded secondary source verification criteria low for the initial calibration. The reported results should be
considered an estimated value.
L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated
samples may be biased high.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
N2 The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A
complete list of accreditations/certifications is available upon request.
v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.
v2 The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the
associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.
v3 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the
associated samples may have low bias.
