1.0 INTRODUCTION
1.1 Site Information
The Johns River Waste Management Facility (JRWMF) is located in the north -central portion
of Burke County, north of Morganton, North Carolina. The 318-acre landfill property is
bounded by Lower Creek to the north and east, and the Catawba River to the south. The
Catawba River forms Lake Rhodhiss along the southeastern property line (Figure 1). Lake
Rhodhiss is a long, narrow lake formed by the Rhodhiss Hydroelectric Dam located
approximately 12 miles downstream of the landfill. The John's River flows into the Catawba
River near the southwest corner of the landfill property. A Municipal Solid Waste (MSW)
transfer facility is located in the eastern half of the property. A site plan showing all the
pertinent features of the facility is provided in Drawing 1.
The site has rolling topography with elevations ranging from 975 feet to 1,150 feet above
mean sea level (AMSL). The central portion is generally gently sloping and contains the
higher elevations; relatively steep slopes and significant drainage features are located
around the perimeter. The 100-year flood boundary extends onto the landfill property. The
adjacent property to the west of the Johns River Waste Management Facility consists of
undeveloped, heavily wooded land. Properties within 2,000 feet of the landfill boundary are
covered by surface water or are heavily wooded.
An unlined municipal solid waste (MSW) landfill began operation in April 1988 on 28 acres
in the southwest corner of the landfill property, but was closed in 1997 to comply with Rule
.1627(c)(1O)(A) of the NCSWMR, a regulation governing MSW Landfills units that were not
designed with a base liner and leachate collection system. Burke County operated a
permitted Construction and Demolition (C&D) disposal area on top of the closed MSW
landfill between 1998 and 2015 that closed in 2016. The results of the November 2020
semiannual sampling event for the C&D-over-MSW landfill will be presented in a separate
report.
Permit 1203-CDLF-2014, Permit to Construct for Phase 1A of the C&D landfill expansion,
was issued in March 2014, and the County completed construction in July 2014. On August
14, 2014, a Permit to Operate for Phase 1A was issued to the County by the North Carolina
Department of Environment and Natural Resources, now the Department of Environmental
Quality (NCDEQ). A permit to construct was issued for two additional expansions (Phases 2A
and 4) by the NCDEQ on February 07, 2018.
Construction of Phase 2A was completed during the summer of 2018, and Phase 2A
received a temporary permit to operate after construction in a permit modification from the
NCDEQ dated November 7, 2018. The Phase 4 expansion is currently under construction
and is expected to be completed in mid 2021. In accordance with the facility approved
Water Quality Monitoring Plan (WQMP) dated May 2018 (revised November 2018), there
were three groundwater monitoring wells designated as compliance wells for Phase 1A of
Burke County - Johns River Landfill, C&D Expansion, Permit No. 12-03 LaBella Associates
November 2021 Semiannual Water Quality Monitoring Report March 2021

the C&D Expansion: MW-21 (background), MW-20, and MW-38. MW-22S was abandoned in
February 2018 for construction of Phases 2A and 4. In accordance with the November
2018 revision to the May 2018 WQMP, four new monitoring wells were added to the
compliance network for Phases 2A and 4. MW-23S and MW-35 are designated as
compliance wells for Phases 2A and 4, while MW-24S and MW-30 are designated as
compliance wells for Phase 4 only. In a Background Sampling Report dated June 27, 2019,
we noted that MW-24S was mislocated and we recommended it be removed from the
compliance network. In a letter dated July 9, 2019, NCDEQ approved the request.
1.2 Site Geology
The JRWMF is located in the Inner Piedmont Belt of the Piedmont Physiographic Province,
and in close proximity to the Brevard Shear Zone. It is underlain by highly metamorphosed
rocks including gneiss and schist, as well as calc-silicate rocks, felsic rocks, and
metavolcanic rocks. The dominant rock type at the facility is biotite-muscovite schist, as
seen in outcrops, boulders, and rock cores located on site. The structures within limited
outcrops indicate that these rocks are complexly -folded, with attitudes that vary from vertical
to horizontal. The site regolith is typical of the inner piedmont and consists mostly of silty
sand, clayey sand, and sandy silt. The regolith is up to 100 feet thick and varies in thickness
with topography.
An abundance of rounded gravel, cobble, and boulder -sized alluvial deposits are exposed
along the banks of the Catawba River, which borders the site. The greatest accumulation of
these deposits is along the southwestern site boundary. These river deposits are 40 feet or
more above the current river elevation and have been described as ancient river terrace
deposits.
1.3 Regulatory Status
The following report of groundwater monitoring data from the JRWMF C&D expansion has
been prepared in accordance with the NCSWMR 15A NCAC 13B §.0544-.0545 and
§.1630-.1633. The Phase 1A and Phase 2A expansions are currently operating under the
Detection Monitoring Program. The Phase 4 expansion is still under construction and does
not yet have a permit to operate.
Session Law 2018-65, House Bill 573, approved on June 25, 2018, allows for annual
groundwater monitoring frequency at stand-alone C&D landfill facilities in detection
monitoring, as noted in the NCDEQ Solid Waste Section Memorandum dated July 13, 2018.
On behalf of Burke County, La Bella submitted a Request to Reduce Water Quality
Monitoring Frequency to Annual for the Johns River C&D Expansion Landfill to the NCDEQ-
SWS on July 9, 2020. This request was approved by the NCDEQ in a letter dated July 16,
2020.

2.0 FACILITY MONITORING PROGRAM
2.1 Groundwater Monitoring Program
The compliance groundwater monitoring network originally consisted of one upgradient well
(MW-21), and three downgradient wells (MW-20, MW-22S and MW-38). MW-22S was
abandoned in February 2018 for construction of Phases 2A and 4. In accordance with the
WQMP dated January 2018, four new monitoring wells were added to the compliance
network. MW-35 and MW-23S are designated as compliance wells for Phases 2A and 4,
while MW-30 is designated as compliance well for Phase 4 only.
The following is a summary of the compliance monitoring wells:

Groundwater samples are collected semiannually and analyzed for constituents according to
the WQMP. The compliance well samples are analyzed for 40 CFR Part 258, Appendix I,
incorporated by reference into the NCSWMR (NC Appendix 1) organics and inorganics plus
C&D parameters and 1,4-dioxane, as required for routine assessment or detection
monitoring during both semiannual events.
In January 2014, in response to the County's permit application for the C&D expansion area,
the NCDEQ requested that additional wells and/or piezometers in the vicinity of Phases 1
and 2 of the expansion be sampled. Following is a summary of the additional non-

The additional piezometers/wells are to be sampled for the C&D-over-MSW landfill's organic
contaminants of concern (COCs) (excluding alpha-BHC and beta-BHC), plus methane.
2.2 Surface Water Monitoring Program
The current surface water monitoring points are SMP-5, SMP-6, and SMP-7. Surface water
monitoring point SMP-5 (located at the southwestern property line) and SMP-6 (located at
the southeastern property line) are both located downstream from existing sediment basins.
Surface water monitoring point SMP-7 is located downstream from the Phase 1A expansion
area. The surface water monitoring program is designed to monitor for possible impacts
from both the C&D over MSW Landfill and the C&D Expansion Landfill; surface water
samples are analyzed for the NC Appendix I list of constituents plus detected NC Appendix II
constituents from the C&D-over-MSW landfill (cyanide, tin, mercury,
dichlorodifluoromethane, alpha-BHC, and beta-BHC) and 1,4-dioxane during both
semiannual events. In addition, surface water samples are analyzed for hardness to
determine appropriate hardness -based NC2B Standards for some metals.
The surface water at JRWMF is classified as Class WS-IV, meaning that it serves as a water
supply in moderately to highly developed watersheds (15A NCAC 02B §.0101 (c)). This
classification dictates the NC 2B standard that applies for each constituent.

3.0 NOVEMBER 2020 SEMIANNUAL SAMPLING EVENT
3.1 Field Work
3.1.1 Groundwater Sampling
On November 2-4, 2021, personnel from La Bella Associates visited the JRWMF to purge and
collect groundwater samples from monitoring wells MW-15S, MW-20, MW-21, MW-23S,
MW-30, MW-35, MW-36, MW-38, PZ-12, PZ-30S, and PZ-31. Depth -to -water measurements
were obtained to the nearest 0.01 foot using an electronic water level indicator for all
Burke County - Johns River Landfill, C&D Expansion, Permit No. 12-03 LaBella Associates
November 2021 Semiannual Water Quality Monitoring Report March 2021

monitoring wells in the compliance network prior to purging. The November 2021
groundwater elevations data are presented in Table 1.
Monitoring wells were purged and sampled using disposable bailers or a 12-volt
submersible pump. Measurements of temperature, pH, specific conductivity, dissolved
oxygen, oxidation reduction potential, and turbidity were recorded in the site log book as well
as on field data logs prior to purging, after each purge volume, and before sampling. Field
sampling logs for the November 2021 event are provided in Appendix 1.
Laboratory -supplied containers were prepared and labeled (either by the laboratory or in the
field, as indicated) with the following information:
• Monitoring well number (completed by field personnel),
• Date and time of sample collection (completed by field personnel),
• Initials of sampling personnel (completed by field personnel),
• Project name and number (completed by the laboratory),
• Chemical preservative (completed by the laboratory); and
• Requested chemical analysis (completed by the laboratory).
Groundwater samples from each monitoring well were dispensed directly from the
disposable bailers or directly from the 12-volt pump discharge tube into the provided
laboratory containers within 24 hours of the final purge volume. Immediately after
collection, the samples were placed in a laboratory -provided cooler and chilled with ice.
3.1.2 Surface Water Samoling
Surface monitoring point SMP-6 was sampled during the November 2021 sampling event;
however, SMP-5 and SMP-7 did not have sufficient flow to sample. Surface water samples
were collected directly from stream flow by lowering a clean, unpreserved sample container
into the stream flow, and then carefully dispensing it into the laboratory -prepared sample
containers. Care was taken to avoid sample -induced turbidity. At the time of sampling,
surface water was measured for temperature, pH, specific conductivity, dissolved oxygen,
oxidation reduction potential, and turbidity and recorded in the site log book as well as on
field data logs. After sample collection, the samples were placed in a laboratory -provided
cooler and chilled on ice. Field sampling logs are provided in Appendix 1.
3.2 Laboratory Analysis and Quality Control
The November 2021 groundwater and surface water samples were submitted to Pace
Analytical Services, Inc. of Huntersville, North Carolina under chain -of -custody control for
analysis. The November 2021 groundwater samples were analyzed for the NC Appendix I
list of constituents, plus additional required C&D parameters and 1,4-dioxane. Surface
water samples were analyzed for the NC Appendix I list of constituents plus detected NC
Appendix II constituents from the old C&D-over-MSW landfill (cyanide, tin, mercury,
dichlorodifluoromethane, alpha-BHC, and beta-BHC), plus 1,4-dioxane and hardness. As a
quality control measure, LaBella Associates requested a Level II data report for the final
Burke County - Johns River Landfill, C&D Expansion, Permit No. 12-03 LaBella Associates
November 2021 Semiannual Water Quality Monitoring Report March 2021

laboratory report. As stated in the laboratory reports, the samples were received by the
laboratory in good condition, properly preserved, and within required hold times.
In addition to samples collected for compliance monitoring at the JRWMF and as a quality
control measure, a Field Blank was collected by LaBella personnel as part of the November
2021 sampling event. Also, a Trip Blank prepared by the laboratory accompanied the
volatile sampling containers from and to the laboratory. The Field Blank was analyzed for
the NC Appendix I, plus previously detected NC Appendix II list of constituents, plus iron,
manganese, tetrahydrofuran, and 1,4-dioxane, and the Trip Blank was analyzed for NC
Appendix I list of constituents plus additional detected NC Appendix II volatile organic
compounds, tetrahydrofuran, and 1,4-dioxane.
Upon receipt of the laboratory data package, LaBella personnel reviewed the data package
for quality assurance/quality control (QA/QC) purposes and for possible regulatory issues. If
any QA/QC or regulatory issues were found, the laboratory would be contacted to resolve the
issue, and a resampling event might be scheduled, if needed. The laboratory analytical
packages can be found in Appendix 1 of this report. The data packages were reviewed for
the following:
• General typographical errors;
• Correct analyses performed and within method specified hold times;
• Biased data results based on Surrogate Recoveries, Matrix Spike, Matrix Spike
Duplicate, and Laboratory Control Samples;
• Blank -qualified data (B-flags);
• Groundwater detections exceeding the North Carolina 15A NCAC 2L .0202
Groundwater Standards (NC2L) or Interim maximum Allowable Concentrations
(IMAC);
• Surface water detections exceeding North Carolina 15A NCAC 2B Surface Water
Standards (NC2B), NC In -Stream Target Values (ISTV), or EPA National
Recommended Water Quality Criteria (NRWQC); and
• Detections that are above historical levels.
4.0 HYDROGEOLOGICAL CONDITIONS
Based on outcrop and drilling information, the water table appears to occur within regolith
everywhere across the site. This regolith consists of residual soils, and saprolite. Beneath
the regolith lies variably fractured and weathered metamorphic bedrock. Water in the
bedrock is transmitted primarily through fractures; however, even in the saprolite there is
often enough relict structure for former fracture zones to influence groundwater flow. Along
the low-lying areas of the Catawba River and its tributaries, the water table occurs within
surficial alluvial deposits overlying the residual soils and weathered bedrock.
Static groundwater depth was measured in the compliance monitoring wells at the site prior
to sampling. The November 2021 groundwater elevations are provided in Table 1 and the
Burke County - Johns River Landfill, C&D Expansion, Permit No. 12-03 LaBella Associates
November 2021 Semiannual Water Quality Monitoring Report March 2021
6

historical groundwater elevations are provided in Appendix 2, Table A2-1. The elevations
were calculated relative to the surveyed measuring point (top of casing) for each monitoring
well. A groundwater potentiometric surface map, developed from the static water level data
is presented as Drawing 1. The potentiometric surface map depicts groundwater flow
primarily to the south. Groundwater discharges into creeks to the east and west of the
landfill and to the Catawba River to the south.
Horizontal groundwater gradients along representative flow paths were estimated from the
November 2021 groundwater contours shown on Drawing 1 and are summarized in Table 2.
Horizontal gradients across the site ranged from 0.0327 to 0.0481, with an average of
approximately 0.0399. This is consistent with previous estimates.
Linear groundwater flow velocities for wells screened in saprolite were computed using the
modified Darcy equation:
V = Ki/ne,
where:
V = average linear velocity (feet/year),
K = hydraulic conductivity (feet/day),
i = horizontal hydraulic gradient, and
ne = effective porosity.
The average of hydraulic conductivities from slug -tests conducted at the facility (K = 3.28
feet/day) was used in these calculations, along with an effective porosity of ne = 0.40 (40%)
based on laboratory porosities for soil samples from the facility. The estimated linear
groundwater flow velocity under the facility ranged from 100-150 feet/year, with an
average flow velocity of approximately 119 feet/year (Table 2). The modified Darcy equation
makes the simplified assumptions of a homogeneous and isotropic porous aquifer.
Migration of groundwater contaminants are expected to follow the general groundwater flow
paths and there are no known preferred pathways or barriers to groundwater flow that could
significantly affect plume migration or the effectiveness of the groundwater monitoring
network to monitoring plume migration. The current groundwater monitoring network
remains sufficient for monitoring the groundwater at this facility.
5.0 ANALYTICAL RESULTS
The complete laboratory reports and chains -of -custody for the November 2021 sampling
event for the C&D Expansion Area, as well as the February 2022 resample, are included in
Appendix 1. The constituents detected above the Method Detection Limit (MDL) in one or
more of the compliance monitoring wells, additional wells/piezometers, or surface
monitoring points are presented in Table 3. The constituents in exceedance of their
respective standards in one or more of the compliance monitoring wells, additional
wells/piezometers, or surface monitoring points are presented in Table 4. Field parameters

constituents are presented in Tables A2-3 and A24 in Appendix 2. Historical detected
surface water constituents are presented in Table A2-5 in Appendix 2.
5.1 Inorganic Constituents in Groundwater
On June 3, 2020, Labella submitted an Alternate Source Demonstration (ASD) for metals to
NCDEQ and NCDEQ approved the ASD on June 9, 2020. The ASD established background -
based Groundwater Protection Standards (GPS) for cobalt, iron, manganese, and vanadium.
The following 17 inorganic constituents were detected above the method reporting limit
(MRL) in one or more monitoring wells during the November 2021 sampling event: Alkalinity
(total as CaCO3), arsenic, barium, beryllium, cadmium, chloride, chromium, copper, iron,
lead, manganese, nickel, silver, sulfate, thallim, vanadium, and zinc. Four inorganic
constituents were detected above their respective NC2L, IMAC, or background -based
standards in one or more monitoring wells during the November 2021 sampling event.
Chromium, iron, and lead were reported in exceedance of their background -based standard
in monitoring wells MW-20, MW-35, and MW-38. Vanadium was reported above its
background -based standard in monitoring wells MW-35 and MW-38. Cobalt was reported
above its background -based standard in monitoring well MW-36. Additionally, arsenic and
manganese were detected above their background -based standard in monitoring well
MW-38. The results of the February 17t", 2022 resampling event confirmed the exceedance
of chromium MW-20. These results are generally consistent with historical data found in
Table A2-3 and Table A2-4 (Appendix 2).
5.2 Organic Constituents in Groundwater
The following organic constituents were detected at quantified concentrations above the
MRL in monitoring wells during the November 2021 sampling event: 1,1-dichloroethane,
1,4-dichlorobenzene, 1,4-dioxane (p-dioxane), acetone, benzene, chlorobenzene, cis-1,2-
dichloroethene, ethylbenzene, tetrachloroethene, tetrahydrofuran, trichloroethene, vinyl
chloride, and xylene. 1,4-dichlorobenzene, 1,4-dioxane (p-dioxane), benzene, and
tetrahydrofruan were in exceedance of their NC2L standards in monitoring wells MW-36 and
MW-38. In general, the detections and concentrations are consistent with historical data
presented in Tables A2-3 and A24 (Appendix 2).
MW-36 and MW-38 are located between the old C&D-over-MSW landfill and the C&D
Expansion landfill. It appears that the VOCs detected in monitoring wells MW-36 and
MW-38 are related to landfill gas migration from the old C&D-over-MSW landfill and do not
represent a release from the C&D Expansion Landfill. For more detailed discussion of these
exceedances, see the November 2020 WQMR for the C&D-over-MSW landfill.
5.3 Analytical Results for Surface Water
During the November 2021 sampling event, iron and manganese were detected in SMP-6 in
exceedance of the EPA's National Recommended Water Quality Criteria (NRWQC). There
were no other exceedances of NC213 standards, ISTVs, or NRWQCs. SMP-5 and SMP7 were

November 2021 Semiannual Water Quality Monitoring Report March 2021

dry and could not be sampled. Historical surface water data can be found in Table A2-5
(Appendix 2).
5.4 Statistical Analyses
Statistical evaluation of background for iron, manganese, thallium and vanadium were
presented in the June 2020 Alternate Source Demonstration (ASD). We recommend
preparing an addendum to the ASD to calculate a background value for chromium.
6.0 CONCLUSIONS
Arsenic, chromium, cobalt, iron, lead, manganese, vanadium, benzene, 1,4-dioxane,
1,4-dichlorobenzene, tetrachloroethene were detected above their respective groundwater
protection standards (GPS) in monitoring wells MW-36 and MW-38 during the November
2021 sampling event; however, these exceedances are believed to be due to landfill gas
migration from the C&D-over-MSW Landfill and are being addressed in the January 2018
addendum to the August 2013 Corrective Action Plan for that landfill, which was approved
by the NCDEQ in a letter dated February 7, 2018. These results are generally consistent
with historical data from the site.
The exceedances for chromium, lead, and iron in MW-20 and MW-35 and for vanadium in
MW-35 are unusual. The resampling results for chromium in MW-20 confirmed that
exceednacne. We recommend further sampling and examination of chromium and possible
development of an Alternate Source Demonstration (ASD).
Iron and manganese were detected in SMP-6 in exceedance of the NRWQC. The
groundwater flow regime is consistent with previous events and the groundwater monitoring
network remains adequate to monitor the site.
Based on analytical results from the November 2021 sampling event, the C&D Expansion
Area of the Johns River Landfill will remain in Detection Monitoring pending the results of
the ASD. The next annual sampling event is tentatively scheduled for May 2022.

Notes:
Hydraulic conductivity (K =3.28 ft/day) is based on the average K from individual slug tests in saprolite wells at the facility.
Effective Porosity (n e = 0.40) is assummed to be slightly less than the average laboratory porosity for site soil samples (saprolite) = 44% (0.44).
Gradient segments are based on the November 2021 groundwater potentiometric surface map (see Drawing 1).
V = Kiln e; assumes a homogeneous, isotropic, porous aquifer.

QUALIFIERS
Project: BURKE CO JOHNS R BACKGROUND
Pace Project No.: 92570480
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
IH This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results 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.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
R1 RPD value was outside control limits.
ST Surrogate recovery was above laboratory control limits. Results may be biased high.
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.

QUALIFIERS
Project: BURKE CO JOHNS R BACKGROUND
Pace Project No.: 92571068
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: BURKE CO JOHNS RIVER C&D EXP
Pace Project No.: 92571062
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
IH This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be
considered an estimated value.
R1 RPD value was outside control limits.
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.

QUALIFIERS
Project: Burke Co. Johns River C&D Exp.
Pace Project No.: 92570731
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
R1 RPD value was outside control limits.
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.

QUALIFIERS
Project: Burke Co. Johns Riv. Add. MWs
Pace Project No.: 92570738
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: BURKE CO JOHNS RIV ADD MWsPZs
Pace Project No.: 92571054
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.

QUALIFIERS
Project: BURKE CO JOHNS RIVER RESAMPLE
Pace Project No.: 92589126
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.

Notes:
All concentrations in micrograms per liter (pg/1) = parts per billion.
RL = Reporting Limit (SWSL).
DL = Laboratory Detection Limit.
--- = Not sampled for this parameter or Not reported.
ND = Not Detected at or above the DL.
J = Estimated value - concentration is less than the RL but greater than the DL.
B = Blank -Qualified (Similar concentrations detected in field, trip, or method blanks).
NC2L = Groundwater Standard from 15A NCAC 2L.O2O2.
GWPS = Groundwater Protection Standard set by NC-DEQ-SWS for constituents with no listed NC2L standard (no longer used).
IMAC = NC Interim Maximum Allowable Concentration for constituents with no listed NC2L standard.
Values above the NC2L Standard, IMAC, or GWPS are bold.

Notes:
All concentrations in micrograms per liter (pg/1) = parts per billion.
DL = Laboratory Detection Limit.
RL = SWSL = Solid Waste Section Reporting Limit.
NC 2L = Groundwater Standard from 15A NCAC 2L.0202.
nle = No longer exists (MW-34 was accidentaly destroyed during construciton activties).
--- = Not reported or not monitored
MW-36 was converted from PZ-36.
ND = Not Detected above the DL.
J = Estimated value - Concentration is less than the SWSL but greater than the DL.
B = Blank -Qualified (Similar concentration detected in field, trip, or method blank).
Values above the NC 2L Standard are bold
Italics = Constituent of Concern (COC).
*Resampling event due to laboratory error.

Notes:
All concentrations in micrograms per liter (pg/I) = parts per billion.
RL = Method Reporting Limit
DL = Laboratory Method Detection Limit.
ND = Not Detected at or above the RL (prior to Dec. 2006) or the DL (after Dec. 2006).
J = Estimated value - concentration is less than the RL but greater than the DL.
B = Blank -Qualified (Based on similar concentrations detected in field, trip, or method blanks).
INC 2B = Groundwater Standard from 15A NCAC 2B.
NI = Monitoring well not yet installed.
AB = Monitoring well abandoned.
= Not sampled for this parameter or Not reported
NE = No NC 2B established.
Values above the NC 213 Standard are bold.
Surface waters classified as WS-IV (water supply IV, highly developed), B (primary recreation, fresh water), and CA (critical area).
*NC 2B Groundwater Standards and Protective Values include acute and chronic exposure levels for designated metals
based on dissolved metal and in -stream water hardness results. Site specific values may be calculated based on water hardness at time of sampling.
