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 (MSL). 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 May 2019
semiannual sampling event for the C&D-over-MSW landfill will be presented in a separate
report.
A 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. 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), on August 14, 2014. A
permit to construct was issued for two additional expansions (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 2019. 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: 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
Burke County - Johns River Landfill, C&D Expansion, Permit No. 12-03 LaBella Associates
May 2019 Semiannual Water Quality Monitoring Report August 2019

May 2018 WQMP, four new monitoring wells were added to the compliance network for
phases 2A and 4. MW-35 and MW-23S 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.

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.
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-24S and MW-30 are designated as compliance wells for Phase 4 only.
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. The County agreed to sample PZ-31, PZ-30S, PZ-34,
MW-36 (formerly PZ-36), PZ-12, and MW-15S semiannually beginning with the spring 2014
sampling event. The County also agreed to sample the following wells/piezometers in the
event of Groundwater Protection Standard (GWPS) exceedances in the referenced
wells/piezometers, as follows:
• PZ-30D will be added in the event that there are GWPS exceedances at PZ-
30S;
• PZ-35 will be added in the event that there are GWPS exceedances at PZ-34;
• MW-15D will be added in the event that there are GWPS exceedances at
MW-15S;
• PZ-16S will be added in the event that there are GWPS exceedances at PZ-35
or PZ-12; and
• PZ-16D will be added in the event that there are GWPS exceedances at
PZ-16S.
PZ-34 was inadvertently destroyed during the spring of 2014; so, PZ-35 was
sampled instead; however, PZ-35 was converted to MW-35 in February 2018
and is now a compliance well.

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).
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 Phase 1A C&D 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. 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 213 standard that applies for each
constituent.

3.0 FIRST SEMIANNUAL SAMPLING EVENT OF 2018
3.1 Field Work
3.1.1 Groundwater Sampling
On May 7-8, 2019, personnel from LaBella Associates visited the JRWMF to purge and
collect groundwater samples from monitoring wells MW-15S, MW-20, MW-21, MW-23S,
MW-24S, MW-30, MW-35, MW-36, MW-38, PZ-12, PZ-30S, and PZ-31. On May 22, 2019,
personnel from LaBella Associates visited the JRWMF to purge and collect the remaining
groundwater samples from monitoring well MW-21. Depth -to -water measurements were
Burke County - Johns River Landfill, C&D Expansion, Permit No. 12-03 LaBella Associates
May 2019 Semiannual Water Quality Monitoring Report August 2019

obtained to the nearest 0.01 foot using an electronic water level indicator for all monitoring
wells in the compliance network prior to purging. The May 2019 groundwater elevations
data are presented in Table 1. A resampling event was conducted on July 24, 2019, for
monitoring well MW-35. 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 data logs for the May 2019 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 the 12-volt pump 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.
On July 24, 2019, personnel from LaBella were on -site to collect a detection verification
sample from monitoring well MW-35. The monitoring well was sampled using low -flow
methodology, and measurements of temperature, pH, specific conductance, dissolved
oxygen, oxidation reduction potential, and turbidity were recorded in the site log book and on
the sampling data log prior to purging, at five minute intervals during purging, and at the
time of sampling. The groundwater sample from monitoring well MW-35 was collected
directly from the discharge tube of the geotech bladder pump in the laboratory -provided
sample bottle immediately after purging. Immediately after collection, the sample was
placed on ice in a laboratory -provided cooler. Analytical reports, chain -of -custody
documents, and field sampling logs for the resampling event are provided in Appendix 1.
3.1.2 Surface Water Samalin
Surface monitoring points SMP-5, SMP-6, and SMP-7 were sampled during the May 2019
sampling event. 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. After sample collection, the samples were placed in a laboratory provided
cooler and chilled on ice. Field data logs are provided in Appendix 1.

May 2019 Semiannual Water Quality Monitoring Report August 2019

3.2 Laboratory Analysis and Quality Control
The May 2019 groundwater and surface water samples, as well as the July 2019
groundwater samples, were submitted to Pace Analytical Services, Inc. of Huntersville, North
Carolina under chain -of -custody control for analysis. The May 2019 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 11 constituents from the old C&D-over-MSW
landfill (cyanide, tin, mercury, dichlorodifluoromethane, alpha-BHC, and beta-BHC). As a
quality control measure, LaBella Associates requested a Level 11 data report for the final
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 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 11 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 and
tetra hyd rofu ra n.
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 package was 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);
• Detections exceeding the North Carolina 15A NCAC 2L .0202 Groundwater
Standards (NC2L), NCDEQ-SWS Groundwater Protection Standards (GWPS),
and North Carolina 15A NCAC 2B Surface Water Standards (NC2B); 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 alluvium, 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
Burke County - Johns River Landfill, C&D Expansion, Permit No. 12-03 LaBella Associates
May 2019 Semiannual Water Quality Monitoring Report August 2019

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.
Groundwater discharges into creeks to the east and west of the landfill and to the Catawba
River to the south. A groundwater potentiometric surface map, developed from static water
level data obtained in May 2019 is presented as Drawing 1. The potentiometric surface
map depicts groundwater flow primarily to the south.
Static groundwater depth was measured in the compliance monitoring wells at the site prior
to sampling. The May 2019 groundwater elevations are provided in Table 1 and the
historical groundwater elevations are provided in Table A2-1. The elevations were calculated
relative to the surveyed measuring point (top of casing) for each monitoring well. Horizontal
groundwater gradients along representative flow paths were estimated from the May 2019
groundwater contours shown on Drawing 1 and are summarized in Table 2. Horizontal
gradients across the site ranged from 0.0514 to 0.0542, with an average of approximately
0.0532. This is consistent with previous estimates.
Linear groundwater flow velocities for wells screened in saprolite were computed using the
modified Darcy equation:
V = Kiln,
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
ft/day) was used in these calculations, along with an effective porosity of n = 0.40 (40%)
based on laboratory porosities for soil samples from the facility. The estimated linear
groundwater flow velocity under the facility ranged from 154.0-162.3 feet/year, with an
average flow velocity of approximately 159.3 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

compliance monitoring wells, additional wells/piezometers, or surface monitoring points are
presented in Table 3. The constituents in exceedance of their respective NC2L or IMAC in
Burke County - Johns River Landfill, C&D Expansion, Permit No. 12-03 LaBella Associates
May 2019 Semiannual Water Quality Monitoring Report August 2019

one or more of the compliance monitoring wells, additional wells/piezometers, or surface
monitoring points are presented in Table 4. Field parameters for the May 2019 sampling
event are presented in Table 5, and the historical field parameters are presented in Table
A2-2. The complete laboratory reports and chains -of -custody are included in Appendix 1.
5.1 Analytical Results for Inorganic Constituents
Eleven inorganic constituents (barium, chloride, chromium, cobalt, copper, iron, manganese,
nickel, thallium, vanadium, and zinc) were detected above the method reporting limit (MRL)
in one or more monitoring wells during the May 2019 sampling event. Five inorganic
constituents were detected above their respective NC 2L or IMAC in one or more monitoring
wells during the May 2019 sampling event. Iron was reported above its NC 2L standard in
monitoring wells MW-20, MW-21, MW-23S, MW-24S, MW-30, MW-35, and MW-38.
Manganese was reported above its NC 2L standard in monitoring wells MW-20, MW-21,
MW-23S, MW-30, MW-35, and MW-38. An Alternate Source Demonstration (ASD) was
approved for iron and manganese by NCDEQ for the Johns River facility on April 12, 2012;
however, the NCDEQ has asked for ASD's approved before July 2017 be revised in
accordance with the NCDEQ Guidance document for ASD's dated July 2017. May 2019
concentrations of iron and manganese are generally consistent with historical data. Cobalt
was detected above its GWPS in monitoring well MW-38. Vanadium was detected above its
GWPS in monitoring wells MW-21, and MW-35. In all wells that had exceedances of
inorganic constituents, the turbidity was greater than 10 NTU at the time of sampling. The
turbidity and other field parameters at the time of sampling during the May 2019 sampling
event can be found in Table 5.
These results are mostly consistent with historical data (found in Table A2-3 and Table A2-4)
with the exception of new exceedances of iron in monitoring wells MW-23S and MW-35,
manganese in monitoring well MW-23S, and vanadium in monitoring well MW-35. With the
exception of iron and manganese, which have an approved ASD, all of the inorganic
constituents in exceedance of their respective standards display either a stable or
decreasing trend in concentration overtime (Chart A3-2).
5.1.1 Resampling Event
As stated previously, a resampling event was conducted on July 24, 2019. This sample was
collected to confirm the presence of vanadium in monitoring well MW-35, which was in
exceedance of its IMAC during the May 2019 sampling event. Based on the analytical
results of the resampling event, the initial exceedance of vanadium was confirmed. The
results of the resampling event are displayed in Table 4.
5.2 Analytical Results for Organic Constituents
Eight organic constituents (1,1-dichloroethane, 1,4-dichlorobenzene, 1,4-dioxane, benzene,
methylene chloride, tetrachloroethene, trichloroethene, and vinyl chloride) were detected at
Burke County - Johns River Landfill, C&D Expansion, Permit No. 12-03 LaBella Associates
May 2019 Semiannual Water Quality Monitoring Report August 2019

quantified concentrations above the MRL in one or more of the monitoring wells during the
May 2019 sampling event. Five organic constituents (benzene, 1,4-dichlorobenzene, vinyl
chloride, tetrachloroethene, and trichloroethene) were detected above their respective
NC2L/IMAC in one or more of the monitoring wells during the May 2019 sampling event.
Both benzene and 1,4-dichlorobenzene were in exceedance of their NC 2L standards in
monitoring wells MW-36 and MW-38. Tetrachloroethene and trichloroethene were in
exceedance of its NC 2L in monitoring well MW-36, and vinyl chloride was in exceedance of
its NC 2L in monitoring well MW-38.
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. In general, the detections and concentrations are
consistent with historical data and display trends of decreasing concentrations over time,
with the exception of vinyl chloride and 1,4-dichlorobenzene, which show a slight increase in
concentration overtime (Chart A3-1). Historical data for groundwater constituents in
compliance wells are presented in Table A2-3, and historical data for groundwater
constituents in the additional wells/piezometers are presented in Table A2-4.
5.3 Analytical Results for Surface Water
During the May 2019 sampling event, barium, iron, and manganese were detected above
their respective MRL in all surface monitoring points (SMP-5, SMP-6 and SMP-7). Vanadium
was detected in surface monitoring point SMP-5 only. Only copper in SMP-5 was in
exceedance of the NC 2B standards for Class WS-IV waters, which are water supplies in
moderately to highly developed watersheds according to 15A NCAC 02B §.0101(c);
however, iron was detected above the EPA NRWQC in SMP-5 and SMP-6, and manganese
was detected above the EPA NRWQC in SMP-6 and SMP-7. Historical surface water data can
be found in Table A2-5.
5.4 Statistical Analyses
The iron and manganese detections are covered by an approved ASD and the cobalt
exceedance in MW-38 is discussed in the WQMR for the C&D-over-MSW landfill; therefore,
no statistical analyses were conducted for the May 2019 sampling event for the C&D
Expansion area.
6.0 CONCLUSIONS
Benzene, 1,4-dichlorobenzene, tetrachloroethene, trichloroethene, and vinyl chloride were
detected above their respective NC2L standards in MW-38 and/or MW-36 during the May
2019 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 that was approved by
the NCDEQ in a letter dated February 7, 2018. No other organic constituents were detected
Burke County - Johns River Landfill, C&D Expansion, Permit No. 12-03 LaBella Associates
May 2019 Semiannual Water Quality Monitoring Report August 2019

above the IMAC in any of the C&D Expansion compliance monitoring wells. These results
are consistent with historical data from the site, which can be found in Table A2-3 and Table
A2-4. Trend charts showing changes in concentration over time for organic constituents that
have had recent exceedances of NC 2L or GWPS standards can be found in Chart A3-1.
The inorganic constituents in exceedance of NC 2L or GWPS standards during the May 2019
sampling event include iron (MW-20, MW-21, MW-23S, MW-24S, MW-30, MW-35, MW-38),
cobalt (MW-38), manganese (MW-20, MW-21, MW-23S, MW-30, MW-38), and vanadium
(MW-21, MW-35). The exceedance of vanadium in monitoring well MW-35 was confirmed in
the July 24, 2019 resampling event. An ASD was approved for iron and manganese by
NCDEQ on April 12, 2012, and the fact that iron and manganese concentrations during the
May 2019 sampling event are generally consistent with historical data indicates that the
exceedances of these constituents are not related to the landfill. The historical groundwater
data can be found in Table A2-3 and Table A2-4. Trend charts showing changes in
concentration over time for constituents that have had recent exceedances of NC 2L or
IMAC standards can be found in Chart A3-2. Cobalt was detected above its respective IMAC
in MW-38; however, it is addressed in the WQMR for the C&D-over-MSW landfill. All
inorganic results are consistent with historical data.
There were no organic detections above the NC2B Surface Water Standards for surface
water samples from the May 2019 sampling event. Iron was detected above the EPA
NRWQC in SMP-5 and SMP-6, and manganese was detected above the EPA NRWQC in SMP-
6 and SMP-7. Copper exceeded the NC2B Surface Water Standard in SMP-5.
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 May 2019 sampling event, Phases 1A and 2A of the
Johns River Landfill will remain in Detection Monitoring. The next semiannual sampling
event is tentatively scheduled for December of 2019.

QUALIFIERS
Project: BURKE CO. JOHNS RIVER C&D EXP.
Pace Project No.: 92428642
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.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.

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.
me = 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/1) = parts per billion.
RL = Method Reporting Limit
DL = Laboratory Method Detection Limit.
NI = Monitoring well not yet installed.
AB = Monitoring well abandoned.
- = Not sampled for this parameter or Not reported
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).
D = Sample was diluted when analyzed.
NC 2B = Groundwater Standard from 15A NCAC 2B.
NE = No NC 2B established.
Values above the NC 2B 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.
