Subject: November 2021 Semi -Annual Groundwater Sampling Report
North Wake Closed Unlined Landfill
Facility Permit No. 9209-MSWLF-1984
Dear Ms. Drummond:
CDM Smith Inc. (CDM Smith), on behalf of Wake County (County), is submitting an electronic copy of
the November 2021 semi-annual sampling event report. This letter report presents the results of the
semi-annual sampling event that was recently completed at the North Wake Closed Unlined Landfill
(Site) and constitutes the second semi-annual sampling event for 2021. The groundwater monitoring
network consists of the following wells: MW-11 (shallow background well), -11d (deep background
well), -5R, -6, -6d, -7, -8, -8d, -9, -10, -10d, -22, -23, -23d, -24, -28, -28d, -29d, -30, -31, -31d, -32, -33,
-34, -34d, -35, -36, -36d, TB-1a and TB-1a deep. Surface water sampling locations include SW-2, -3, -7,
and -8. Field activities, sampling results for all wells and surface water locations, an evaluation of the
groundwater corrective action effectiveness, and recommendations are discussed below.
Field Activities
Groundwater and surface water samples from the Site were collected on November 9-11, 2021,
except for MW-28, -28d, -33, and -35, which are sampled during the spring semi-annual sampling
event, and MW-24, -30, and TB-1a, which were dry during the November 2021 sampling event.
Monitoring well and surface water sample locations are shown on Figure 1. Construction details for
each monitoring well are summarized in Table 1.
Samples were collected from the monitoring wells by use of a peristaltic pump or disposable,
laboratory decontaminated bailers. Groundwater elevations were measured at each well on
November 9, 2021, prior to sampling using an electronic water level indicator with an accuracy of 0.01
feet and are presented in Table 1. These groundwater elevations were used to construct
potentiometric contours for this sampling event and are shown on Figure 1. The groundwater
elevations and potentiometric contours were also used to estimate groundwater velocities at each
well as presented in Table 2.

After depth to groundwater was measured, three well volumes of water were removed from each
well prior to sampling to provide fresh formation water within the well water column. Each well
volume and surface water sample were measured for pH, conductivity, temperature, turbidity,
dissolved oxygen (DO), and oxidation-reduction potential (ORP) using a YSI-556 multi -parameter
water quality meter and a HANNA HI 98703 turbidity meter. Wells that had elevated turbidity (i.e.,
greater than 10 Nephelometric Turbidity Units) were allowed to stabilize prior to sample collection.
The water quality measurements at the time of sample collection are provided in Table 3.
Alternate Source Demonstration
On August 17, 2020, CDM Smith submitted an Alternate Source Demonstration (ASD) for the Site on
behalf of the County. The purpose of the ASD was to demonstrate that metals exceeding the 15A
NCAC 02L .0202 (NC 2L) Groundwater Standards or Interim Maximum Allowable Concentrations
(IMAC) are naturally occurring and not related to a release from the landfill. The ASD was prepared
using analytical data from the background monitoring wells, MW-11 and -11D, that was collected on a
quarterly basis from January 2018 to April 2020 to develop upper tolerance limits (UTLs) for specific
analytes that historically exceeded their respective NC 2L Groundwater Standard or IMAC. Based on
statistical analysis, a UTL of 6 parts per billion (ppb) was proposed for cobalt and a UTL of 23 ppb was
proposed for vanadium. The North Carolina Department of Environmental Quality's (NCDEQ) Solid
Waste Section (SWS) approved these proposed UTLs on August 17, 2020.
Sampling Results
All groundwater and surface water samples were analyzed by Pace Analytical Services, LLC located in
West Columbia, South Carolina, for North Carolina Appendix I volatile organic compounds (VOCs) plus
dichlorodifluoromethane and Appendix I metals plus mercury. Samples from monitoring wells
MW-5R, -6, -8, -9, -10, -11, -34, -34d, and -36 were also analyzed for natural attenuation parameters
(i.e., biochemical oxygen demand (BOD), chemical oxygen demand, alkalinity, nitrate, chloride,
sulfate, sulfide, total organic carbon, carbon dioxide, methane, ethane, ethene, ferrous iron, volatile
fatty acids, and dissolved hydrogen) per the Corrective Action Plan (CAP) and CAP Addendum that
were approved by the SWS in March 2010 and on June 10, 2019, respectively. Monitoring wells
MW-5R, -34, and -34d were also analyzed for total iron, sodium, and total dissolved solids. The CAP
and CAP Addendum are discussed below.
In a letter dated May 29, 2018, the SWS stated that all groundwater and surface water samples
collected from landfills be analyzed for 1,4-dioxane after July 1, 2018. On June 26, 2019, the SWS
approved the removal of 1,4-dioxane from the sampling program for all monitoring wells and surface
water locations, with the exceptions of MW-6, -8, and -9, due to two non -detect events (October 2018
and April 2019). Samples were collected from the wells requiring the 1,4-dioxane analysis during the
November 2021 sampling event. Sample results are provided below.

The analytical results were reported to the laboratory specific method detection limit (MDL) and are
quantifiable at or below the laboratory limit of quantitation (LOQ). All monitoring wells for the Site
had detections of analytes above the MDL but below the LOQ that were qualified as estimated or "J"
flags.
In samples collected from MW-5R and -9, detections of BOD were qualified with "1" flags, indicating
that the average concentration was lower than the valid range. MW-5R and -9 also had detections of
methane with "E" flags, indicating that the quantitation of the compound exceeded the calibration
range. Additionally, MW-6 had an "E" flag detection of nitrate.
In samples collected from MW-5R, -34, and -36, detections of chloride had "D" flags, indicating that
the analyte was analyzed at a dilution greater than 1. MW-6 also had detections of nitrate and sulfate
with "D" flags. Additionally, MW-9 had a detection of methane with a "D" flag. MW-11, -34, and -36
also had detections of nitrate with "D" flags.
In samples collected from MW-6, a detection of nitrate had an "H" flag, indicating that the analyte
was analyzed outside of hold time. MW-9 also had a detection of methane with an "H" flag. In
samples collected from MW-9 and -10, detections of sulfate had "B" flags, indicating that the analyte
was detected in the method blank. In samples collected from MW-34, a detection of iron had an "S"
flag, indicating a matrix spike/matrix spike duplicate failure.
The following list summarizes which analytes were detected above the LOQ at each sample location.
Underlined analytes exceeded the NC 2L Groundwater Standard, IMAC, or UTL. There were no
detections in the surface water samples that exceeded the 15A NCAC 02B (NC 2B) or North Carolina
In -Stream Target Value Surface Water Quality Standard for Class C Waters. No "J" flag detections are
listed. A complete summary of all detected and estimated concentrations from the November 2011
through the November 2021 sampling events is presented in Table 4. Laboratory data reports are
provided in Appendix A.

"J" flags were not included in the previous list, but MW-9 had a "J" flag detection of thallium that
exceeded its IMAC. It is likely that the recent and historic detections of chloroform in wells MW-6d,
-24, -31, -31d, -32, TB-1a, and -1a deep are attributed to a release from a municipal water line in the
Falls River development and are not related to a release from the Site.
In a letter dated March 22, 2012, the SWS approved the County's request to discontinue collecting
samples from select wells for herbicide and pesticide analyses during the semi-annual spring sampling
event. However, the SWS requested that MW-29d continue to be sampled for bis(2-ethylhexyl)
phthalate during spring sampling events due to a detection from the March 2011 event.
Bis(2-ethylhexyl) phthalate was detected above the NC 2L Groundwater Standard (3 parts per billion
(ppb)) at 28.5 ppb in samples collected from MW-29d during the April 2014 sampling event. A
confirmatory sample collected from MW-29d during the November 2014 sampling event had an
estimated detection of bis(2-ethylhexyl) phthalate at 4.61 ppb, which is above the standard. Bis(2-
ethylhexyl) phthalate has not been detected above the laboratory MDL in samples collected from
MW-29d since the November 2014 sampling event, except for estimated detections below the NC 2L
Groundwater Standard in samples collected during the 2018 and April 2020 events. The concentration
trend for bis(2-ethylhexyl) phthalate in MW-29d will continue to be evaluated.
An equipment and three trip blanks were analyzed for quality control. A duplicate sample was also
collected for quality control. Acetone was detected as an estimated concentration and chloroform
was detected in the equipment blank below their respective NC 2L Groundwater Standards. There
were no detections in the trip blanks above the MDLs. The duplicate sample, identified as DUP, was
collected from MW-23d, and had similar analyte concentrations as those detected in MW-23d. Table
5 presents a summary of all analytes detected during the November 2021 sampling event that
exceeded the NC 2L Groundwater Standards, IMACs, or UTLs.

Corrective Action via Air Sparging
The SWS expressed concern in May 2008 that VOCs may be migrating beyond the Site property
boundary and into Abbott's Creek based on detections above the NC 2L Groundwater Standard in
monitoring well MW-9. As a result, the SWS directed the County to install and sample groundwater
monitoring wells, one shallow and one deep (i.e., MW-36 and -36d), downgradient of MW-9 to
determine if VOCs may be migrating beyond the Site property boundary, possibly discharging into
Abbott's Creek. Initial groundwater samples collected from MW-36 and -36d in December 2008 had
detections of VOCs above NC 2L Groundwater Standards.
Surface water sample locations SW-7 and -8, located on Abbott's Creek, were added to the semi-
annual monitoring program in November 2008. Samples collected from SW-7 and -8 since being
added to the monitoring program have never had VOCs detected above the NC 2B Surface Water
Quality Standards.
An Assessment of Corrective Measures Report was submitted to the SWS in accordance with the
North Carolina Solid Waste Management Rule 15 NCAC 13B .1635 and approved in December 2009.
The SWS approved the selected remedy of monitored natural attenuation paired with in situ
remediation by air sparging to address groundwater contamination at the facility. A pilot test was
conducted in July and August 2010 near MW-6 and -6d to evaluate the effectiveness of the air
sparging remedy and to collect data for the full-scale system design in accordance with the CAP. The
pilot test successfully reduced the concentrations of 1,1-dichloroethane and vinyl chloride to below
their respective NC 2L Groundwater Standard in MW-6d and vinyl chloride was not detected in
samples collected from MW-6 during the October 2010 semi-annual sampling event.
The full-scale system was installed in October 2011 and was operational in August 2012. The air
sparging system consists of 15 shallow wells screened across saturated saprolite and partially
weathered rock and 14 wells screened in the shallow fractured bedrock. In addition to the air sparging
wells, the system also consists of an air compressor and control panel that are housed in a secured
on -site control building. Routine inspections are performed on the system and a Field Inspection Log
completed during each inspection is kept on file at the facility.
The County installed a vacuum extraction system around the perimeter of the Site in January 2002 to
prevent offsite migration of soil gas. The air sparging system was designed to work in tandem with the
existing perimeter migration control system (PMCS) by recovering air and gas vapors produced by the
air sparging system. Since previous work has indicated a relationship between the soil gas and the
contaminated groundwater, the installation of the PMCS is likely to further reduce groundwater
contaminant concentrations. As discussed in the approved CAP, the vacuum extraction system will be
used in conjunction with the air sparging system to reduce VOCs in the bedrock and partially
weathered rock between MW-9 and the MW-6 nested pair.

As part of the corrective action effectiveness evaluation, contaminant concentration trends for
monitoring wells MW-6, -6d, -9, -36, and -36d were evaluated. Total VOC concentration trends for
each well are presented on Figures 2 through 6. Trend results for each well are discussed below.
Figure 2 presents a total VOC concentration trend analysis for samples collected from MW-6. VOCs in
MW-6 significantly decreased after January 2002 when the PMCS was operational and were not
detected from November 2004 to April 2007. The total VOC concentration in MW-6 increased in May
2008 to 24 ppb compared to the November 2007 concentration of 14 ppb. The total VOC
concentration in MW-6 showed a decreasing trend from May 2008 to April 2018 but has increased
since the introduction of the 1,4-dioxane analysis in October 2018. The total VOC concentration in
MW-6 has fluctuated since October 2018.
Vinyl chloride has not been detected above the laboratory MDL in MW-6 since the April 2013
sampling event. Benzene detections in MW-6, which historically have exceeded the NC 2L
Groundwater Standard, have been below the laboratory MDL since April 2013 except for the
November 2014 sampling event when it was detected slightly above the standard at 1.1 ppb and
October 2018 when it was detected above the MDL at 0.61 ppb.
The trend analysis for total VOC concentrations in MW-6d is presented on Figure 3. VOCs were not
detected at MW-6d from December 2001 through November 2007. The increase in total VOCs from
samples collected during the May 2008 sampling event is a result of reporting "J" flag detections as
required by the SWS. VOC concentrations in MW-6d have been below the NC 2L Groundwater
Standards since the March 2011 sampling event and show a decreasing trend.
Figure 4 presents a total VOC concentration trend analysis for samples collected from MW-9.
Historically, MW-9 has had the highest concentration of VOCs compared to the other monitoring
wells. VOCs were not detected as an estimated concentration above the NC 2L Groundwater
Standards in MW-9 from October 2012 through April 2015. Benzene, 1,4-dichlorobenzene, 1,2-
dichloroethane, 1,4-dioxane, and vinyl chloride have recently been detected above their respective
NC 2L Groundwater Standards in MW-9. The total VOC concentration trend has been slightly
increasing at MW-9 since the October 2018 sampling event.
Trend analyses for total VOC concentrations in MW-36 and -36d are presented on Figures 5 and 6,
respectively. Vinyl Chloride was detected above its NC 2L Groundwater Standard during the October
2020 sampling event for the first time in samples collected from MW-36 since March 2011, and was
detected above the standard during the November 2021 sampling event. However, total VOC
concentrations have shown a decreasing trend since the air sparging system has been operational. No
VOCs have been detected above the NC 2L Groundwater Standards in MW-36d since the October
2015 sampling event. Total VOC concentrations in both monitoring wells will continue to be
monitored and are expected to decrease while the air sparging system is operational.

Additional groundwater samples were collected from MW-51R, -6, -8, -9, -10, -11, and -36 for
evaluation of monitored natural attenuation parameters as part of the corrective action program as
required by SWS guidelines. Geochemical results are presented in Table 6. The laboratory data for the
additional parameters is included in Appendix A.
As discussed in the approved CAP, concentrations of some of the natural attenuation data from select
wells indicates that environments are present which favor reductive dechlorination; notably, the
concentrations of nitrate, ferrous iron, sulfate, and carbon dioxide. The following evidence indicates
that one or more mechanisms of natural attenuation and/or reductive dechlorination may be
occurring at the site:
• VOC concentrations in contaminated wells continue to decline;
• The ratio of parent to daughter compounds continues to decrease over time;
• Nitrate, ferrous iron, sulfate, and carbon dioxide continue to be detected at concentrations
favoring reductive dechlorination; and
• Concentrations of cis-1,2-dichloroethene continue to be greater than dichloroethene isomers
trans-1,2-dichloroethene and 1,1-dichloroethene.
Corrective Action via In Situ Bioremediation Injection
VOCs that exceed the NC 2L Groundwater Standards, including benzene, 1,4-dichIorobenzene,
1,1-dichloroethane, methylene chloride, PCE, TCE, and vinyl chloride, have been detected in the area
of MW-51R, -34, and -34d. MW-5R is located near the Site property line and the MW-34 cluster is
located east of MW-5R on the adjacent parcel, more than 900 feet from the air sparging system. The
VOC exceedances are likely from the migration of leachate from the Site into the surficial aquifer.
In accordance with the CAP Addendum that was approved by the SWS on July 10, 2019, and an
injection permit obtained from the Division of Water Quality — Underground Injection Control
Program on July 24, 2019, an in situ enhanced anaerobic bioremediation (EAB) injection was
completed by adding sodium lactate and emulsified vegetable oil (EVO) substrates through a
biobarrier injection system to reduce total VOC concentrations at the property line. Sodium lactate
and EVO enhance biologically reducing conditions that favor and support dechlorination of VOCs to
non -toxic end products.
On August 26-28, 2019, eight injection wells (i.e., NWIW-1 through -8) were installed upgradient of
MW-51R, -35, and -34d, as shown on Figure 1. An initial injection of sodium lactate was completed
from October 8-16, 2019. A total of 54,181 gallons of a 2.4 percent sodium lactate solution were
injected. Post -sodium lactate injection samples were collected 1 month after the injection during the
November 2019 semi-annual sampling event. Samples collected from monitoring wells MW-51R, -34,

and -34d were analyzed for natural attenuation parameters, sodium, total iron, and total dissolved
solids. Analytical results are summarized in Tables 4 and 6.
The EVO injection was completed on November 18-30 and December 1-6, 2019, with a 3.3 percent
solution of 98 percent LactOil° EVO formulation. A total of 80,751 gallons of the solution was injected.
The effectiveness of the EAB injection was evaluated with quarterly sampling of MW-5R, -34, and -34d
on February 4, April 8, July 30, and October 15, 2020. A report summarizing the results of the EAB
injection was submitted to the SWS on June 23, 2021. Chlorinated VOC data were reviewed to
evaluate concentration trends over time and to determine if dechlorination is occurring. Total VOC
concentration trends for each well are presented on Figures 7 through 9. Trend results for each well
are discussed below.
The VOC trend analysis for MW-5R is presented on Figure 7. TCE has never been detected above the
NC 2L Groundwater Standard in MW-5R and PCE has never been detected above the MDL, except
during the April 2019 sampling event when PCE was detected as an estimated concentration below
the standard. Vinyl chloride was the most recent analyte detected above the NC 2L Groundwater
Standard (April 2019). The geochemical data indicates reducing conditions to support anaerobic
dechlorination at MW-5R, shown by decreasing levels of sulfate, nitrate, DO, and negative values of
ORP. Additionally, total VOC concentrations show a decreasing trend since the injection events.
The trend analyses for MW-34 and -34d are presented on Figures 8 and 9, respectively. Since the
injections, total VOC, PCE, TCE, and 1,1-dichloroethane concentrations have fluctuated.
Concentrations of methylene chloride and cis-1,2-dichloroethene show a decreasing trend in MW-34.
Total VOC concentrations in MW-34d have slightly increased, but concentrations of chlorinated VOCs
are expected to decrease as the reducing conditions at the upgradient biobarrier support
dechlorination.
Recommendations
The County will continue with the semi-annual assessment monitoring program. In addition to
sampling for Appendix I metals plus mercury, Appendix I VOCs plus dichlorodifluoromethane, and the
Appendix II constituent, bis(2-ethylhexyl) phthalate (sampled at MW-29d only during the spring
sampling event), samples collected from MW-51R, -6, -8, -9, -10, -11, -34, -34d, and -36 will continue to
be analyzed for natural attenuation parameters during the semi-annual events. MW-6, -8, and -9 will
continue to be analyzed for 1,4-dioxane.
The air sparging system will continue to operate and the effectiveness of the system will be
re-evaluated after the next semi-annual sampling event in the spring of 2022.

Notes:
1. All units are in micrograms per liter (parts per billion).
2. * - Interim Maximum Allowable Concentration (IMAC)
3. ** - The upper tolerance limits (UTL) were calculated as part of the North Wake Unlined Alternate Source Demonstration and were approved by the
Solid Waste Section on August 17, 2020.
3. dup - Duplicate Sample
4. (41 - Monitoring wells were not sampled due to an insufficient volume of water in the well.
5. J - Indicates the analytical result is an estimated concentration between the method detection limit and the limit of quantitation.
6. S - Matrix spike/matrix spike duplicate failure
7. B - The analyte concentration detected in the method blank was greater than the method detection limit.
8. D - Dilution greater than 1
9. Monitoring wells MW-28, -28d, -33, and -35 are sampled yearly during the spring event.
10. Dissolved metal samples were collected to evaluate the influence of turbidity on total metal concentrations.
11. NA - Not Analyzed

Revised Report 12/21/2021:
Per client, this PDF report has been revised to report VOA samples WK10045-001 (MW-7), -002
(MW-23d), -003 (MW-10d) & -004 (MW-9) all on one result form with the H flag reported for trans-
1,4-Dichloro-2-butene. Sample WK10045-033 (MW-11) that was outside of holding time for toluene
& xylenes has also been reported all on one result form with H flags for these two analytes.
Sample WK10045-022 (Trip Blank) was originally analyzed outside the 7 day holding time for the
intimal analysis and the Run 2 for this sample has been combined on one form. All other sample
results are as reported in the original PDF report. This report supersedes and replaces any prior
reports issued under this lot number.
This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample. All results listed in this report relate only to the samples that are contained
within this report.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace")
Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to
the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or
discussed below.

The reanalysis for the following samples was analyzed outside holding time for trans-1,4-Dichloro-2-
butene: WK10045-001 (MW-7), WK10045-002 (MW-23d), WK10045-003 (MW10d) and WK10045-004
(MW-9). Both runs have been reported together.
The following sample was analyzed outside of analytical holding time due to the labor shortage along with
an abundance of samples for trans- 1,4-Dichloro-2-butene: (Trip Blank). The sample was also reanalyzed
outside of hold time due to trans-1,4 marked off for ICAL associated with run 1.
WK10045-033 (MW-11) were analyzed outside of analytical holding time due to oversight and the
abundance of samples in the lab.
The method blank for analytical batch 22900 contained analytes: Carbon Disulfide, 1,2-Dibromo-3-
chloropropane, 1,2-Dibromoethane, Dibromomethane, trans- 1,4-Dichloro-2-butene, 1,2-Dichlorobenzene,
1,4-Dichlorobenzene, cis-1,3-Dichloropropene and trans- 1,3-Dichloropropene greater than the
acceptance criteria. The associated samples, WK10045-021 (MW-31) and WK10045-023 (MW-23), did

not contain detections for the target analyte; therefore, re -analysis of sample(s) was not performed. The
data has been reported.
Reanalysis of the following sample(s) was performed outside of the analytical holding time for trans-1,4-
Dichloro-2-butene due to failing in the ICAL: WK10045-001 (MW-7), WK10045-002 (MW-23d), WK10045-
003 (MW-10d), and WK10045-004 (MW-9). Also, reanalysis of sample WK10045-001 (MW-7) was
performed outside of the analytical holding time for Xylenes due to carryover.
Reanalysis of sample WK10045-033 (MW-11) was performed outside of the analytical holding time. The
Run 1 had suspected carry over of Toluene and Xylenes.
Dissolved Gases RSK175
Samples WK10045-004 (MW-9) and WK10045-027 (MW-5R) required a dilution which was performed
outside of the analytical holding time. Both runs have been reported.
Metals 6020B
The MSD for batch 22464 and parent sample WK10045-026 (MW-34), recovered marginally outside the
lower limit. The associated LCS and MS passed acceptance criteria.
Sulfate
The method blank for analytical batch 22344 contained sulfate greater than the acceptance criteria. The
associated samples, WK10045-018 (MW-10) and WK10045-020 (MW-9), did not contain detections for
the target analyte; therefore, re -analysis of samples was not performed. The data has been reported.
The following sample WK10045-027 (MW-5R) was diluted due to the nature of the sample matrix. The
LOQ has been elevated to reflect the dilution.
The method blank associated with batch 22344 had Sulfate detected at a concentration that was above
the LOQ. All samples associated with this method blank that have detections for Sulfate have been
flagged with a "B".
Nitrate-N
The following samples, WK10045-020 (MW-9) and WK10045-027 (MW-5R) was diluted due to the nature
of the sample matrix. The LOQ has been elevated to reflect the dilution.
Reanalysis of sample WK10045-020 (MW-9) was performed outside of the analytical holding time. This
sample was reanalyzed OOH due to matrix interference upon initial analysis. Both runs have been
reported.
This sample WK10045-014 (MW-6) was reanalyzed OOH due to the sample's raw result being over linear
range, yielding a reported result of 18mg/L. The sample was diluted at a 5x during run 2 and yielded a
reported result of 18mg/L, as well. Both runs have been reported.
Sulfide
The MS/MSD for batch 22578 and WK10045-01 (MW-10), recovered outside the lower control limit. The
associated LCS passed acceptance criteria.

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.
