Spring 2025 Semi -Annual Water Quality Monitoring Report
Greenway Waste Solutions of Apex, LLC
Apex, North Carolina
June 11, 2025
1.0 Introduction
This Semi -Annual Water Quality Monitoring Report has been prepared to document the methods
and results of the semi-annual groundwater monitoring event conducted in Spring 2025 at the
Greenway Waste Solutions of Apex, LLC (GWSA) C&D Landfill (Site). This report details well
gauging and field sampling activities, summarizes the site groundwater conditions and analytical
data, and provides conclusions and recommendations for future monitoring events.
1.1 Site Description & Background
The subject landfill facility is owned and operated by GWSA under Solid Waste Facility Permit
Number 92-30. The Site, formerly known as the Highway 55 C&D Landfill, is located at 5940
Old Smithfield Road, Apex, North Carolina. A site location map is provided as Figure 1. The
Site is bounded by the Triangle Expressway (Interstate 540) to the north, Highway 55 to the east,
the South Wake Landfill to the south, and privately -owned property to the west. Tributary
streams to Little Branch occupy the southern and western property boundaries. Site layout and
monitoring well locations are depicted in Figure 2.
The facility was originally permitted on August 20, 2002 under North Carolina Department of
Environmental Quality Solid Waste Section (NCDEQ SWS) permit number 92-30. The Phase 1
and Phase 2 landfilling area footprints contain approximately 32.6 acres, and the currently active
Phase 3 expansion contains approximately 11.2 acres.

2.0 Sampling & Analysis Conducted
Groundwater monitoring activities for the Spring 2025 sampling event were conducted in
accordance with the North Carolina Department of Environmental Quality Solid Waste Section
(SWS)-approved Updated Water Quality Monitoring Plan prepared by Civil & Environmental
Consultants, Inc. (CEC) dated February 13, 2020. Groundwater sampling activities were
conducted on April 29 and 30, 2025 by GWSA personnel. GWSA returned to the site on May
15, 2025 to resample all monitoring wells for total dissolved solids due to a laboratory error.
GWSA personnel returned to the site again on May 21, 2025 to confirm a detection of benzene in
MW-9 as well as resample MW-10 for total dissolved solids due to another laboratory error.
Project oversight was provided by an NC -licensed geologist. Sampling activities included water
level measurements, static water purging, and groundwater sample collection from fourteen
monitoring wells: MW-1, MW-2 MW-3, MW-4, MW-5, MW-6, MW-7, MW-8, MW-9, MW-10,
MW-11R, MW-12, MW-13R and MW-14. Samples were also collected from four surface water
locations: SW-1, SW-2, SW-3R, and SW-4, as well as the leachate storage tanks. The
approximate locations of these monitoring wells and surface water sampling locations are
depicted on Figure 2.
2.1 Water Level Measurements
Prior to monitoring well purging, depth -to -water was measured in each of the site monitoring
wells on April 29, 2025. Depth -to -water measurements were collected from the top of casing
utilizing a decontaminated electronic water level indicator. Water level measurements and
calculated groundwater elevations are summarized in Table 1.
2.2 Groundwater Sampling Methods
The shallow wells were purged using low flow methods in general accordance with the Solid
Waste Section Guidelines for Groundwater, Soil, and Surface Water Sampling Revision 4-08. A
peristaltic pump with polyethylene tubing was used to purge and sample each shallow well using
low flow purging and sampling techniques. The pump tubing was positioned in the approximate
mid -portion of the screened interval of each well. Water levels were monitored during the
2 e Griffin 9raMea Co
GreenWa lUaste Solutions

purging process to ensure the purging rate did not cause significant drawdown of the water
column. Samples were collected following stabilization of field parameters and when turbidity
readings were below 10 nephelometric turbidity units (NTUs). Field measurements of pH,
temperature, specific conductivity, oxygen reduction potential (ORP), and dissolved oxygen
(DO) were measured using a YSI Pro Plus water quality meter equipped with a flow -through
cell. Turbidity was measured using an HF Scientific MicroTPW turbidity meter. Copies of the
groundwater sampling field forms are provided in Appendix A.
2.3 Surface Water Sampling Methods
Surface water samples were collected from two unnamed tributaries of Little Branch in general
accordance with Solid Waste Section Guidelines for Groundwater, Soil, and Surface Water
Sampling Revision 4-08. Surface water samples SW-1 and SW-2 were collected from the
tributary along the southern property boundary, and SW-3R and SW-4 were collected from the
tributary located west of the landfill (Figure 2). Surface water sampling was conducted starting
downstream and working upstream.
2.4 Sample Handling and Analyses
Following the well purging procedures described above, samples for laboratory analysis were
placed directly into dedicated laboratory -supplied sample bottles, labeled, and placed on ice in an
insulated cooler. A chain -of -custody record was completed and included sample identification,
analyses required, matrix, and date and time of sample collection. The samples were transported
on ice, under standard chain -of -custody protocol, to Eurofins TestAmerica's (ETA) Charlotte
office for shipment to ETA's laboratory in Chicago, I1. The laboratory analytical reports and
chain -of -custody records are provided in Appendix B.
Groundwater samples collected from each sample location were analyzed by ETA for the
constituents listed in 40 CRF 258 Appendix I, in accordance with 15A NCAC 13B
.0544(b)(1)(D):

sample, collected from MW-8, to TA for analysis of Appendix I VOCs plus THE and 1,4-
dioxane for quality control purposes. Additionally, GWSA submitted one split sample, collected
from MW-8, to Pace Analytical Services, LLC (Pace) for analysis of Appendix I VOCs plus
THE and 1,4-dioxane only.

3.0 Findings
3.1 Groundwater Flow
A summary of monitoring well gauging and water level elevation data is provided in Table 1.
Utilizing water table elevation data derived from well gauging measurements, GWSA created a
generalized potentiometric map depicting shallow groundwater flow beneath the active landfill
area (Figure 3). Shallow groundwater in the northeastern portion of the Site generally flows
southwest towards an unnamed tributary of Little Branch. Shallow groundwater movement
beneath the eastern portion of the landfill is semi -radial, such that shallow groundwater in the
northwestern portion of the Site generally flows to the northwest toward a tributary of Little
Branch located to the northwest of the landfilling area, and shallow groundwater in the central
portion of the Site generally flows west toward another tributary of Little Branch. Shallow
groundwater in the southern portion of the site generally flows southwest toward the tributary of
Little Branch which forms the southern property boundary.
Horizontal Shallow Groundwater Gradient
The horizontal hydraulic gradient (i) used in the flow velocity calculation below was estimated
between the upgradient well MW-1 and downgradient well MW-5, which are separated by a
horizontal distance of approximately 2,700 feet. Based on the calculated groundwater elevations
for the April 2025 event, the hydraulic head difference between MW-1 (347.44 ft) and MW-5
(279.58 ft) is 67.86 feet. The horizontal hydraulic gradient, which is calculated by dividing the
difference in hydraulic head (67.86 ft) by the horizontal well separation distance (2,700 ft), is
0.025 (unitless).
Horizontal Shallow Groundwater Hydraulic Conductivity and Flow Velocity
In order to estimate the horizontal hydraulic conductivity of the shallow water bearing zone, slug
tests were conducted in MW-6 during August 2013 by Elite Techniques, Inc. The mean K
calculated from the slug test data is 4.54 x 10-5 cm/sec (= 0.13 ft/day, or 47.45 ft/year). As
described in the Well Installation Report — Phase III Expansion dated March 10, 2020, additional
slug testing was performed in January 2020 by GWSA personnel in MW-12, MW-13R, and
MW-14 following the installation of these wells in accordance with the facility Permit to Operate
5 A6„ffinaomeaCo
GreenWa lUaste Solutions

(PTO). Determined K values for MW-12 (3.84 x 10-6 cm/sec), MW-13R (1.15 x 10-6 cm/sec),
and MW-14 (1.05 x 10-5 cm/sec), are generally consistent with the value determined for MW-6.
Based on the known typical absence of significant fracturing within the massive conglomerate
beneath the landfill footprint, the K values derived from slug testing appear to be higher than
typical values for unfractured rock from the scientific literature (10-8 cm/s, or 10-2 ft/year).
Monitoring well gauging data from the October 2024 monitoring event, and determined aquifer
properties described above, were used to estimate groundwater seepage velocity and specific
discharge (Table A). An average effective porosity of 0.6% (0.006) was utilized based on
calculated values for MW-12, MW-13R, and MW-14. An average K of 0.043 ft/day (1.52 x 10-5
cm/sec) was utilized based on K values derived from slug testing of MW-6, MW-12, MW-13R,
and MW-14. The groundwater seepage velocity was estimated with the following equation:
Where:
V = Kxi
Tie
V = groundwater flow velocity (ft/sec)
K = horizontal hydraulic conductivity (ft/sec)
i = horizontal hydraulic gradient (dh/dl, unitless)
dh = difference in hydraulic head between wells (ft)
d1= distance between wells (ft)
Ile = effective porosity (%)
The specific discharge of the surficial aquifer was estimated with the following equation:
Where:
q=Kxi
q = specific discharge (ft/sec)
K = horizontal hydraulic conductivity (ft/sec)
i = horizontal hydraulic gradient (dh/dl, unitless)
dh = difference in hydraulic head between wells (ft)
d1= distance between wells (ft)

3.2 Groundwater Analytical Results
A summary of Appendix I VOCs, metals, and inorganic analytes detected in the groundwater
samples at concentrations above their respective laboratory reporting limits is provided in Table
2A, and a summary of current and historical detections of PFAS compounds are provided in
Table 2B. The laboratory analytical data reports are provided in Appendix B. Historical
analytical detections above their respective laboratory reporting limits are provided in Table 4.
VOCs
The analytical data for the Spring 2025 monitoring event indicates that 1,4-dioxane was detected
at concentrations which exceed the North Carolina Administrative Code Title 15A Subchapter
2L Groundwater Classifications and Standards (2L Standards) of 3 µg/L in MW-8 (5.8 µg/L) and
MW-9 (16.0 µg/L). The detection in MW-8 was confirmed by the Pace split sample.
The analytical report indicates that benzene was detected at a concentration of 1.5 µg/L in MW-
9, which slightly exceeds the 2L Standard of 1.0 µg/L. The analytical report for the May 21
confirmation sample from MW-9 indicates benzene was detected at a concentration of 1.1 jig/L.
No other VOCs were detected at concentrations which exceed their respective 2L Standard.
PFAS
NCDEQ SWS established Interim Maximum Allowable Concentrations (IMACs) for eight PFAS
compounds in a memorandum dated October 15, 2024. PFAS compounds perfluorooctanoic
acid (PFOA) and perfluorooctanesulfonic acid (PFOS) were detected at concentrations which
exceed their respective IMACs of 0.001 ng/L and 0.7 ng/L in MW-1, MW-2, MW-3, MW-4,
7 B Griffin BraMea Co
GreenWa lUaste Solutions

MW-5, MW-6, MW-7, MW-8, MW-9, MW-11R, and MW-12. Detected PFOS concentrations
also exceeded the IMAC in MW-13R and MW-14.
The analytical reports indicate that perfluorohexanesulfonic acid (PFHxS) was detected in MW-
2, MW-3, MW-4, MW-8, MW-9, and MW-11R at concentrations which exceed the IMAC of 10
ng/L.
According to the analytical reports, perfluorononanoic acid (PFNA) was detected at
concentrations which slightly exceed the IMAC of 10 ng/L in MW-2 (11.0 ng/L), MW-4 (12.0
ng/L), MW-8 (14.0 ng/L), and MW-9 (13.0 ng/L).
Inor ag nics
The analytical report indicates that detected total dissolved solids (TDS) levels exceeded the 2L
Standard of 500,000 µg/L in MW-I, MW-2, MW-3, MW-8, MW-9, MW-10, MW-11R, MW-12,
MW-13R, and MW-14. Chloride was detected at concentrations which exceed the 2L Standard
of 250,000 µg/L in MW-I, MW-2, MW-8, MW-9, MW-10, MW-11R, MW-12, MW-13R, and
MW-14. It is important note that the highest concentration of TDS (3,400,000 µg/L) was
detected in upgradient monitoring well MW-I.
According the analytical report, barium was detected at concentrations which exceed the 2L
Standard of 700 µg/L in MW-1 (1,100 µg/L), MW-9 (1,200 µg/L), MW-10 (1,800 µg/L), MW-
13R (910 µg/L), and MW-14 (1,800 µg/L). The consistency with historical detections in these
wells, the fact that barium was detected at an elevated concentration in upgradient monitoring
well MW-I, and was detected above laboratory reporting limits in all sampled monitoring wells
at the Site, suggests that these concentrations reflect naturally occurring groundwater conditions
at the facility.
The analytical report indicates that chromium was detected in cross -gradient well MW-13R at a
concentration of 17.0 µg/L, which exceeds the 2L standard of 10 µg/L.
8 e Griffin 9raMea Co
GreenWa lUaste solutions

The analytical results indicate that cobalt was detected at concentrations which exceed the 2L
Standard of 1.0 µg/L in MW-3 (16.0 µg/L), MW-4 (3.1 µg/L), MW-5 (8.7 µg/L), MW-6 (1.2
µg/L), MW-7 (1.4 µg/L), MW-8 (2.2 µg/L), MW-9 (6.9 µg/L), and MW-11R (6.8 µg/L). The
consistency of these detections with historical detections suggests that they are representative of
naturally occurring cobalt concentrations.
Iron and manganese were detected at concentrations which exceed their respective 2L Standards
in the majority of the samples collected from Site monitoring wells. Detected concentrations of
both iron and manganese were above their 2L Standards of 300 µg/L and 50 µg/L, respectively,
in MW-2, MW-3, MW-4, MW-5, MW-7, MW-8, MW-9, and MW-11R. Manganese was also
detected at a concentration in excess of the 2L Standard in MW-6, MW-10, MW-12, and MW-
14.
Mercury was detected in upgradient monitoring well MW-1 at a concentration of 1.3 µg/L,
which exceeds the 2L standard of 1.0 µg/L. Mercury was also detected at concentrations which
are below the 2L Standard in nearby upgradient/cross-gradient wells MW-14 (0.89 µg/L) and
MW-13R (0.37 µg/L), however mercury was not detected above laboratory reporting limits in
the Leachate sample. The concentration of mercury detected in MW-1 during the Spring 2025
sampling event is consistent with historical detections in this well, which suggests that mercury
may be locally naturally occurring.
Per the NCDEQ SWS-approved Alternative Source Demonstration Addendum, dated April 20,
2018 and prepared by CEC, an alternative source demonstration is being performed to address
2L Standard and IMAC exceedances for chromium, cobalt, iron, manganese, thallium, and
vanadium. CEC will submit an addendum alternative demonstration report to NCDEQ SWS
upon the completion of statistical data analysis, in which an alternative concentration will be
proposed for metals listed above.
3.3 Surface Water Results
A summary of the analytical results for the surface water samples is provided in Table 3. The
9 A6„ffinaomeaCo
GreenWa lUasre Solutions

laboratory analytical data reports are provided in Appendix B. Historical analytical results are
provided in Table 5. Analytical data for surface water is compared to the North Carolina 15A
NCAC 02B Water Quality Standards for Surface Waters (213 Standards) for Aquatic Life &
Secondary Recreation (ALSR), Fish Consumption (FC), and In -Stream Target Values (ISTV) for
Class C streams.
Surface water samples were collected from four locations from Little Branch along the western
property boundary (SW-1 and SW-2) and the tributary to Little Branch which forms the southern
property boundary (SW-3R and SW-4). The approximate surface water sampling locations are
depicted on Figure 2. Surface water samples were analyzed for Appendix I VOCs, THF, and
1,4-dioxane via EPA Method 8260 as well as PFAS by EPA Draft Method 1633. Surface water
regulatory standards for PFAS have not been established, and the analytical results indicate that
no VOCs were detected at concentrations above laboratory reporting limits.

4.0 Conclusions & Recommendations
Groundwater samples were collected from fourteen Site monitoring wells at the Greenway Waste
Solutions of Apex, LLC C&D Landfill by GWSA personnel and Groundwater sampling
activities were conducted on April 29 and 30, as well as May 15 and May 21, 2025. In addition,
four surface water samples were collected from tributary creeks of Little Branch along the
southern and western property boundaries.
4.1 Conclusions
Historically, dissolved VOC/SVOC constituents in groundwater at this site have been generally
below NCDEQ 2L standards since the development of Phase I of our C&D Landfill. Analytical
data from the Spring 2025 sampling event indicates that 1,4-dioxane, which is one of the most
prevalent VOCs in C&D Landfills across the state due to its relatively high solubility in
groundwater, was detected at low-level exceedances of the 2L Standard in MW-8 and MW-9.
The only other VOC detected slightly above the 2L Standard is benzene in MW-9. Based on
industry experiences with VOC detections in groundwater resulting from landfill gas (LFG)
integrating at the groundwater interface, GWSA has elected to preemptively install an active
LFG extraction system to limit LFG contact with groundwater. Continuous operation of this
LFG extraction system is expected to lead to a decrease in detected concentrations of VOCs such
as 1,4-dioxane and benzene over time.
Metals barium, cobalt, iron, and manganese were detected at concentrations which exceed their
respective 2L Standard in the majority of samples collected from Site monitoring wells. An
addendum alternative source demonstration report will be submitted by CEC to propose
alterative standard concentrations based on naturally occurring metals concentrations at the Site.
Chromium was detected in cross -gradient monitoring well MW-13R at a concentration of 17.0
µg/L, which exceeds the 2L Standard of 10 µg/L. The fact that MW-13R is located upgradient
of the current extent of landfilled waste, and this concentration is generally consistent with the
historical range of detections for chromium in MW-13R, suggests that the detected concentration
reflects naturally occurring groundwater conditions.
1 1 e Griffin 9raMea Co
GreenWa lUaste solutions

Mercury was detected at a concentration of 1.3 µg/L in upgradient monitoring well MW-I,
which slightly exceeds the 2L Standard for of 1.0 jig/L. Mercury was also detected below the 2L
Standard in cross -gradient monitoring wells MW-13R (0.37 µg/L) and MW-14 (0.89 µg/L), both
of which are currently located upgradient of landfilled waste. Additionally, mercury was not
detected in the Leachate sample and has never been detected in leachate since analysis began in
April 2023. The consistency of these upgradient and cross -gradient mercury detections with
historical detections in these wells, and the fact that mercury was not detected in the leachate
sample, suggests that they may be representative of naturally occurring groundwater conditions
at the facility.
The analytical data indicates that TDS and chloride were detected at concentrations which
exceed their respective 2L Standards in samples collected from both upgradient and
downgradient monitoring wells. Consistent with historical analytical results, the highest
concentration of TDS was detected in upgradient monitoring well MW-I. An upgradient source
for the elevated concentrations of TDS and chloride has not been identified.
4.2 Recommendations
Additional evaluation is required to determine the source of the elevated concentrations of TDS
and chloride which were detected in MW-1, MW-2, MW-3, MW-8, MW-9, MW-10, MW-11R,
MW-12, MW-13R, and MW-14. GWSA will closely monitor concentrations of mercury in
MW-13R and MW-14 as construction and demolition waste is landfilled in more of an
upgradient direction to these wells in the future. Also, additional well purging will be conducted
during sampling activities to minimize turbidity prior to collecting samples.

Method 8260D SIM: The following sample was diluted to bring the concentration of target analytes within the calibration range
Leachate (500-267618-15). Elevated reporting limits (RLs) are provided.
Method 8260D: The continuing calibration verification (CCV) analyzed in batch 500-816639 was outside the method criteria for the
following analyte(s): 1,2-Dibromo-3-Chloropropane, 2-Butanone (MEK), 2-Hexanone, 4-Methyl-2-pentanone (MIBK) and Acetone.
A CCV standard at or below the reporting limit (RL) was analyzed with the affected samples and found to be acceptable. As
indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered
estimated.
Method 8260D: The method blank for analytical batch 500-816639 contained Tetrahydrofuran above the method detection limit.
This target analyte concentration was less than the reporting limit (RL) in the method blank; therefore, re -extraction and/or re-
analysis of samples was not performed.
Method 8260D: The continuing calibration verification (CCV) analyzed in batch 500-816859 was outside the method criteria for the
following analyte(s): Bromomethane and lodomethane. A CCV standard at or below the reporting limit (RL) was analyzed with the
affected samples and found to be acceptable. As indicated in the reference method, sample analysis may proceed; however, any
detection for the affected analyte(s) is considered estimated.
Method 8260D: The following sample(s) was collected in a properly preserved vial; however, the pH was outside the required
criteria when verified by the laboratory. The sample was analyzed outside the 7-day holding time specified for unpreserved
samples but within the 14-day holding time specified for preserved samples: Leachate (500-267618-15).
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
Metals
Method 6020B: The method blank for preparation batch 500-816796 and analytical batch 500-817255 contained Antimony above
the method detection limit. This target analyte concentration was less than the reporting limit (RL) in the method blank; therefore,
re -extraction and/or re -analysis of samples was not performed.

LCMS
Method 1633: The low level continuing calibration verification (CCVL) associated with batch 320-850974 recovered above the
upper control limit for N-ethylperfluorooctanesulfonamidoacetic acid (NEtFOSAA). The samples associated with this CCV were
non -detects for the affected analytes; therefore, the data have been reported. The associated samples are:MW-1 (500-267618-1),
MW-11R (500-267618-2), MW-10 (500-267618-3), MW-2 (500-267618-4), MW-3 (500-267618-5), MW-5 (500-267618-6), MW-6
(500-267618-7), MW-7 (500-267618-8), MW-4 (500-267618-9), MW-12 (500-267618-12), MW-13R (500-267618-13), MW-14
(500-267618-14), Leachate (500-267618-15) and (CCVL 320-850974/5).
Method 1633: The "I" qualifier means the transition mass ratio for the indicated analyte was outside the established ratio limits. The
qualitative identification of the analyte has some degree of uncertainty. The associated analytes have been flagged: MW-11 R
(500-267618-2), MW-7 (500-267618-8), MW-4 (500-267618-9), MW-8 (500-267618-10), MW-13R (500-267618-13) and Leachate

Method 1633: The Isotope Dilution Analyte (IDA) recovery associated with the following samples is below the method
recommended limit: MW-11 R (500-267618-2), MW-8 (500-267618-10), MW-9 (500-267618-11) and Dup-1 (500-267618-16).
Generally, data quality is not considered affected if the IDA signal-to-noise ratio is greater than 10:1, which is achieved for all IDA
in the sample(s).
Method 1633: Isotope Dilution Analyte (IDA) recovery is above the method recommended limit for the following sample: Leachate
(500-267618-15). Quantitation by isotope dilution generally precludes any adverse effect on data quality due to elevated IDA
recoveries.
Method 1633: Internal standard (ISTD) response for the following samples were outside control limits: MW-1 (500-267618-1),
MW-11R (500-267618-2), MW-10 (500-267618-3), MW-2 (500-267618-4), MW-3 (500-267618-5), MW-4 (500-267618-9), MW-8
(500-267618-10), MW-13R (500-267618-13), MW-14 (500-267618-14), Leachate (500-267618-15) and Dup-1 (500-267618-16).
The samples were re -analyzed with concurring results; therefore, the data have been reported.
Method 1633: The "I" qualifier means the transition mass ratio for the indicated analyte was outside the established ratio limits. The
qualitative identification of the analyte has some degree of uncertainty. The associated analytes have been flagged: Leachate
(500-267618-15).
Method 1633: Internal standard (ISTD) response for the following sample was outside control limits: Leachate (500-267618-15).
The sample(s) was re -analyzed and ISTD response was outside control limits.
Method 1633: The "I" qualifier means the transition mass ratio for the indicated analyte was outside the established ratio limits. The
qualitative identification of the analyte has some degree of uncertainty. The associated analytes have been flagged: Leachate
(500-267618-15).
Method 1633: Results for samples MW-9 (500-267618-11) and Leachate (500-267618-15) were reported from the analysis of a
diluted extract due to high concentration of the target analyte and matrix interference in the analysis of the undiluted extract. The
dilution factor was applied to the labeled internal standard area counts and these area counts were within acceptance limits
Method 1633: The Isotope Dilution Analyte (IDA) recovery associated with the following sample is below the method recommended
limit: Leachate (500-267618-15). Generally, data quality is not considered affected if the IDA signal-to-noise ratio is greater than
10:1, which is achieved for all IDA in the sample(s).
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
General Chemistry
Method SM 2540C: The following samples were analyzed outside of analytical holding time because the analysis was added after
the hold time had expired. MW-1 (500-267618-1), MW-11R (500-267618-2), MW-10 (500-267618-3), MW-2 (500-267618-4), MW-3
(500-267618-5), MW-5 (500-267618-6), MW-6 (500-267618-7) and MW-7 (500-267618-8).
Method 9056A: The method blank for analytical batch 500-817823 contained Chloride above the method detection limit. This
target analyte concentration was less than the reporting limit (RL) in the method blank; therefore, re -extraction and/or re -analysis of
samples was not performed.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
Organic Prep
Method 1633: The following samples in preparation batch 320-849840 were observed to have a thin layer of sediment present in
the bottom of the bottle prior to extraction: MW-11 R (500-267618-2), MW-2 (500-267618-4), MW-3 (500-267618-5), MW-6
(500-267618-7) and MW-9 (500-267618-11).
Method 1633: Due to an excess amount of particulates, the following samples were fortified with Isotope Dilution Analyte (IDA)
then centrifuged and decanted back into the original containers: MW-5 (500-267618-6), MW-4 (500-267618-9) and Leachate
(500-267618-15).
Method 1633: The following sample in preparation batch 320-849840 was cloudy and green in color prior to extraction: Leachate
(500-267618-15).
Method 1633: The following samples in preparation batch 320-849840 were yellow in color following extraction: MW-9
(500-267618-11) and Leachate (500-267618-15).

Job Narrative
500-267738-1
Receipt
The samples were received on 5/2/2025 9:20 AM. Unless otherwise noted below, the samples arrived in good condition, and
where required, properly preserved and on ice. The temperatures of the 4 coolers at receipt time were 2.20 C, 5.21 C, 5.20 C and
5.70 C.
GC/MS VOA
Method 8260D: The following analyte(s) recovered outside control limits for the LCS/LCSD associated with analytical batch
500-817054: Bromomethane. This is not indicative of a systematic control problem because these were random marginal
exceedances. Qualified results have been reported.
Method 8260D: The continuing calibration verification (CCV) analyzed in batch 500-817054 was outside the method criteria for the
following analyte(s): Bromomethane, Chloromethane, Trichlorofluoromethane and Vinyl chloride. A CCV standard at or below the
reporting limit (RL) was analyzed with the affected samples and found to be acceptable. As indicated in the reference method,
sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
LCMS
Method 1633: The low level continuing calibration verification (CCVL) associated with batch 320-850974 recovered above the
upper control limit for N-ethylperfluorooctanesulfonamidoacetic acid (NEtFOSAA). The samples associated with this CCV were
non -detects for the affected analytes; therefore, the data have been reported. The associated samples are:SW-1 (500-267738-1),
SW-2 (500-267738-2), SW-3R (500-267738-3), SW-4 (500-267738-4) and (CCVL 320-850974/5).
Method 1633: The "I" qualifier means the transition mass ratio for the indicated analyte was outside the established ratio limits. The
qualitative identification of the analyte has some degree of uncertainty. The associated analytes have been flagged: SW-3R
(500-267738-3) and SW-4 (500-267738-4).
Method 1633: Internal standard (ISTD) response for the following sample was outside control limits: SW-3R (500-267738-3). The
samples were re -analyzed with concurring results; therefore, the data have been reported.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
Organic Prep
Method 1633: The following samples in preparation batch 320-849840 were observed to have a thin layer of sediment present in
the bottom of the bottle prior to extraction: SW-1 (500-267738-1), SW-2 (500-267738-2) and SW-4 (500-267738-4).
No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
VOA Prep
No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.
