Subject: October 2020 Semi -Annual Groundwater Sampling Report
North Wake Closed Unlined Landfill
Facility Permit No. 9209-MSWLF-1984
Dear Ms. Drummond:
CDM Smith Inc., on behalf of Wake County (County), is submitting an electronic copy of the October
2020 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 2020. 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.
Monitoring wells MW-28, -28d, -33, and -35 are sampled annually during the spring event. 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 October 13-15, 2020.
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 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 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 or IMAC standard. Based on statistical
analysis, an UTL of 6 parts per billion (ppb) was proposed for cobalt and an 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 (formerly
Shealy Environmental Services, Inc.) located in West Columbia, South Carolina, for North Carolina
Appendix I volatile organic compounds (VOCs) plus dichlorodifluoromethane and Appendix I metals
plus mercury. Monitoring well TB-1a was not sampled during the October 2020 sampling event due to
the low volume of groundwater in the well and recharge rate.
Samples from monitoring wells MW-5R, -6, -8, -9, -10, -11, -34, -34d, and -36 were analyzed for
natural attenuation parameters (i.e., biochemical oxygen demand (BOD), chemical oxygen demand
(COD), alkalinity, nitrate, chloride, sulfate, sulfide, total organic carbon (TOC), 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
October 2020 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. Chloride, nitrate, TOC, and methane were qualified with "D" flags in samples collected from
MW-5R, indicating that the sample was analyzed at a dilution. Chloride, nitrate, and sulfate were also
qualified with "D" flags in samples collected from MW-6. Nitrate detections in samples collected from
monitoring wells MW-5R, -6, -10, -34, -34D, and -36, as well as the methane detection in MW-11,
were qualified with "B" flags, indicating that the analyte was detected in the method blank.
BOD was qualified with a "4" and "7" flag in samples collected from MW-5R, -9, -10, -11, and -34d,
indicating that the seed correction factor was above the method range and the blank depletion was
above the method limit. This indicates that the BOD results may be biased low. In samples collected
from MW-11, BOD was also qualified with a "1" flag, indicating that the G-G was out of range and the
results should be considered invalid and should only be used for estimation purposes. BOD in samples
collected from MW-5R was also qualified with a "5", indicating that sample became depleted. The
reported result was computed using the greatest dilution and the least amount of sample.
The following list summarizes which analytes were detected above the LOQ at each sample location.
Underlined analytes exceeded the NC 2L Groundwater Standard, IMAC, UTL, or 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 October 2020 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 several locations had "J" flag detections that

listed below.

Vinyl Chloride: MW-8, -36
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 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 NC 2L 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 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.
Equipment and trip blanks were analyzed for quality control. A duplicate sample was also collected for
quality control. There were no detections in the equipment or trip blanks above the MDL. There was

an estimated detection of methylene chloride above the MDL in two of the three trip blanks that were
analyzed. 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 October 2020 sampling event that exceeded the NC 2L Groundwater Standards,
IMACs, or UTLs.
As part of the ASD for the Site, an additional metals sample was collected from monitoring wells
MW-5R, -30, and -31 during the October 2020 sampling event for the laboratory to filter and analyze
due to elevated turbidity (i.e., greater than 10 Nephelometric Turbidity Units) at the time samples
were collected. Total metals that exceeded the NC 2L or IMAC Standards in these wells were analyzed
for dissolved metals to determine if turbidity was a contributing factor to total reported metals.
Based on qualitative and quantitative evaluation of current and historic groundwater sampling data,
the NC 2L, IMAC, or UTL metal exceedances from the October 2020 sampling event were determined
to be indicative of naturally occurring background concentrations as opposed to a release from the
landfill. Below is a summary of the dissolved metals exceedances. Wells with a "*' qualifier had a "J"
flag detection for that analyte. Dissolved metal sample results are provided in Table 4 and the
laboratory data report is provided in Appendix A.

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 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 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 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 concentration of 1,4-dioxane
in samples collected from MW-6 during the October 2018 and November 2019 sampling events was
26 ppb and 24 ppb, respectively. 1,4-Dioxane was also detected in samples collected from MW-6
during the April 2020 and October 2020 sampling events at concentrations of 10 ppb and 16 ppb,
respectively.

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 Standard,
have been below the laboratory MDL since April 2013 with the exception of 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 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 above the NC 2L Standards in MW-9 from October 2012 through April
2015. There were "J" flag detections of 1,2-dichloroethane above the NC 2L Standard in samples
collected from MW-9 during the October 2015, and 2020 sampling events. Vinyl chloride was
detected above the NC 2L Standard in samples collected in April 2016 and from April 2019 to October
2020. Benzene was detected above its NC 2L Standard in April 2019 and in the 2020 sampling events.
1,4-DichIorobenzene was detected above its NC 2L Standard in the 2020 sampling events.
Additionally, 1,4-dioxane was detected above the standard during the 2020 sampling events in
samples collected from 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 standard for the first time in samples
collected from MW-36 since the March 2011 sampling event, but 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 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
0

Smith
Ms. Jaclynne Drummond
December 18, 2020
Page 11
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 Standards, including benzene, 1,4-dichlorobenzene, 1,1-dichloroethane,
methylene chloride, tetrachloroethene, trichloroethene, 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 in order 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 -5) 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 is currently being evaluated with quarterly sampling of MW-5R,
-34, and -34d. The first and second quarterly sampling events were completed in February and April
2020, respectively. The third quarterly sampling event was completed on July 30, 2020. The fourth
quarterly sampling event was completed as part of the October 2020 semi-annual sampling event. A

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 11 constituent, bis(2-ethylhexyl) phthalate (sampled at MW-29d only during the spring
sampling event), samples collected from MW-5R, -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 2021.
If you have any questions or require further explanation, do not hesitate to call me at [phone].
Sincerely,

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. (4) - Monitoring well TB-1a was not sampled due to an insufficient volume of water in the well.
5.1- Indicates the analytical result is an estimated concentration between the method detection limit and the limit of quantitation.
6. B - The analyte concentration detected in the method blank was greater than the method detection limit.
7. Monitoring wells MW-28, -28d, -33, and -35 are sampled yearly during the spring event.
8. Dissolved metal samples were collected to evaluate the influence of turbidity on total metal concentrations as part of an ongoing Alternate Source Demonstration.
9. NA - Not Analyzed
10. D - Dilution > 1
Concentration exceeds the 15A NCAC 02L .0202 (North Carolina 2L) or IMAC Standard.
Indicates the result is below the detection limit.

Geochemical Data
October 2020 Semi -Annual Sampling Event
North Wake Unlined Landfill - 9209-MSWLF-1984
Notes.
1. All units are in milligrams per liter ((mg/L) parts per million), unless otherwise noted.
2. µg/L - micrograms per liter (parts per billion)
3. CaCOs - Calcium Carbonate
4. MW-11 is a background well for the North Wake Unlined Landfill.
5. • - Field analysis performed using a HACH kit.
6. (--) - Not Measured
7.1 - Indicates the analytical result is an estimated concentration between the method detection limit and the limit of quantitation.
8. B -The analyte concentration detected in the method blank was greater than the method detection limit.
9. D, d -Analyzed as dilution.
10. U% - The compound was analyzed for, but not detected. 1 mL HNO3 was added to MW-6 for metals upon receipt to get the pH to Q.
11. (1) - BOD was measured following dilution and did not meet the oxygen depletion criterion of at least 2 mg/L. The elevated BOD concentrations are a result of laboratory error and were not used to evaluate natural attenuation for the April and
November 2014 sampling events.
12. 1- The average BOD for M W-9, -10, -36, and -11 is lower than the valid range.
13. (-) Samples not collected and analyzed for the spring 2016 sampling event.
14. H - The analyte was analyzed outside of holding time.
151�s1- 7 flag - The seed correction factor was above the method range. Results may be biased low.
16. I1°I - 75 flag - The sample became depleted. The reported result was computed using the greatest dilution and the least amount of sample.
17. I"I - M3 flag - The matrix spike duplicate sample recovery was outside laboratory control limits.
18. Issl - M5 flag -The matrix spike sample recovery was outside laboratory control limits.
19. I"I - 47 flag - Indicates a blank depletion >0.20 mg/L and a seed correction factor out of range.
I- Blank cells indicate no data collected

Case Narrative
CDM Smith
Lot Number: VJ15046
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.
Nitrate-N 300.0
The following samples were diluted due to the nature of the sample matrix: VJ15046-011 (MW-5R) and
VJ15046-012 (MW-6). The LOQ has been elevated to reflect the dilution.
Reanalysis of sample VJ15046-014 (MW-9) was performed outside of the analytical holding time. Sample
VJ15046-014 (MW-9) had matrix interferences during the initial analysis, therefore the samples needed to
be diluted and a spiked aliquot of the same dilution was also analyzed to confirm sample results, the data
will be reported. Both sets of results have been reported.
The method blank for analytical batch 70269 contained nitrate greater than the acceptance criteria. The
associated sample, VJ15046-013 (MW-8), did not contain detections for the target analyte; therefore, re-
analysis of sample was not performed. The data has been reported.
The method blank for analytical batch 70269 contained nitrate greater than the acceptance criteria. The
associated samples, VJ15046-012 (MW-6), VJ15046-018 (MW-34D) and VJ15046-019 (MW-36)
contained detections for nitrate at concentrations greater than 10X the value found in the method blank;
therefore sample results are not impacted. The data has been reported.
Samples VJ15046-011 (MW-5R), VJ15046-015 (MW-10) and VJ15046-017 (MW-34) were put in for a
reanalysis (Run 2) due to the fact that the opening CCB/MB had a detection for analyte, nitrate, greater
than 1/2 the LOQ. Upon reanalysis, which was done outside of the analytical hold time, the sample results
were confirmed. Therefore since run 1 was analyzed in hold, this run has been reported.
Chloride 300.0
Sample VJ15046-011 (MW-5R) was diluted due to the nature of the sample matrix. The LOQ has been
elevated to reflect the dilution.
Sulfate 300.0
The following samples were diluted due to the nature of the sample matrix: VJ15046-011 (MW-5R) and
VJ15046-012 (MW-6). The LOQ has been elevated to reflect the dilution.

VOA 8260D
Due to the large number of spiked analytes, there is a high probability that one or more analytes will
recover outside acceptance limits. The laboratory's SOP allows for 10% of analytes to recover marginally
outside criteria. The following analytes recovered marginally outside LCS criteria in batch 70507: trans-
1,4-Dichloro-2-butene (68%).
Reanalysis of sample VJ 15046-001 (MW-11) was performed outside of the analytical holding time:
VJ15046-001. The sample was initially analyzed out of an unpreserved vial at a 5x based on screening
data but was over diluted. The sample was reanalyzed out of an unpreserved vial at a 1x and was out of
hold time with concurring results. Both sets of data have been reported.
BOD
Qualifier 1 - The G-G associated with BOD batch 13640 was out of range at 6.3 mg/L (valid range is
167.5 — 228.5 mg/L). This batch 1340 is only associated with VJ15046-001 (MW-11). The associated
BOD results for this one sample should be considered invalid and only used for estimation purposes. With
the 48 hour holding time and the 5 day BOD process the sample could not be reprocessed.
Qualifier 4 - The blank depletion associated with BOD batch 13641 was 0.35 mg/L (limit is 0.20 mg/L).
This demonstrates a high bias on analytical results.
Qualifier 5 - For sample VJ15046-011 (MW-5R), the BOD result has been reported as a greater than
value due to excessive oxygen depletion at each sample dilution. The sample was prepared with a
standard series of dilutions based on the COD result. The sample depleted out. All sample dilutions
resulted in a final DO concentration of < 1.0 mg/L. The reported BOD/CBOD value is 100 mg/L, which
was computed using the sample dilution volume having the lowest DO concentration (greatest
dilution/least amount of sample). [The sample dilutions performed were appropriate based on the dilutions
noted in the "BOD/CBOD Pre -Established Dilutions" logbook (F-AD-115).
Qualifier 7 — The SCF associated with BOD batch 13640 was 0.08 mg/L (valid range is 0.6 - 1.0 mg/L)
Qualifier 7 — The SCF associated with BOD batch 13641 was 1.6 mg/L (valid range is 0.6 - 1.0 mg/L).
