Executive Summary
On behalf of the City of Greensboro, Golder Associates NC, Inc. (Golder) is submitting the enclosed Water Quality
Monitoring Report, which documents the results of the October 16 - 19, 2018, semi-annual compliance monitoring
event for Phase I at the White Street Landfill.
No Resource Conservation and Recovery Act (RCRA) metals were detected above their respective Practical
Quantitation Limits (PQLs) and groundwater standards during the October 2018 event. During this event,
benzene and 1,4-dichlorobenzene were detected above their respective PQLs and NC 2L Standards in the
sample from downgradient well 1-1 as they have been during previous events. The constituent 1,4-dioxane was
detected at 1-1, 1-2, 1-3, and 1-4 above the PQL and NC 2L Standard for the first time; however, this is the first time
this analyte has been sampled for and this parameter is not required by regulation or permit.
No NC Appendix I constituents were reported above their respective PQLs and applicable surface water
standards during the October 2018 event. Copper was reported at estimated concentrations below the PQL, but
above the Acute Standard in the samples from upstream monitoring point SW-2 and at estimated concentrations
below the PQL but above the Chronic Standard in the samples from upstream monitoring points SW-1 and SW-3
and downstream monitoring point SW-5. Because the concentrations are below their respective PQLs and based
on similar concentrations at upstream and downstream samples, the exceedances do not appear to be related to
landfill activities from the facility and no further action is warranted.
Based on these results, the City of Greensboro will continue groundwater monitoring in accordance with the
requirements outlined in NCSWMR 0.600 Rules. The next semi-annual monitoring event is tentatively scheduled
for April 2019.

1.0 INTRODUCTION
This report summarizes the monitoring results from the October 16 - 19, 2018, groundwater and surface water
sampling at Phase I of the White Street Landfill in Greensboro, North Carolina (NC). The closed municipal solid
waste (MSW) landfill is voluntarily monitored in accordance with Title 15A of the North Carolina Administrative
Code (NCAC) Subchapter 13B. Section 0.600.
The facility is located in central Guilford County and is comprised of a closed, unlined MSW facility (Phase 1), an
active unlined construction and demolition debris (C&D) over MSW facility (Phase 11), an active Subtitle D MSW
facility (Phase III), and an active Type I compost facility. Phase II is currently in Assessment Monitoring and
Corrective Action for several detected volatile organic constituents (VOCs) and inorganic constituents that exceed
their respective groundwater standards. Phase III is in Detection Monitoring.
The facility is owned and operated by the City of Greensboro under Permit Nos. 41-03 and 41-12 issued by the
NC Department of Environmental Quality (DEQ, formerly NC Department of Environment and Natural Resources).
The northeastern portion of the landfill property is comprised of the Phase I and Phase II landfills, which are
covered under Permit No. 41-03. The southwestern portion of the facility is comprised of the Phase III, which is
covered under permit No. 41-12. The water quality monitoring results for the Phase II and Phase III facilities are
submitted under separate cover.
1.1 Site Description and Background
The location of the facility is shown on the inlay on Figure 1. The White Street Landfill is located approximately 5
miles northeast of downtown Greensboro, NC in Guilford County. Access to the site is from Cone Boulevard,
which turns into Ralph Johnson Way and ends at White Street with the landfill entrance to the East of this
intersection.
Part of the James River watershed, North Buffalo Creek flows from southwest to northeast along the northwestern
border of the facility and then flows eastward, away from the facility near the northeastern end of the facility. The
location of this surface water feature and its associated tributaries are shown on the inlay on Figure 1.
Based on the topography as shown on Figure 1, topographic surface elevations at the facility range from
approximately 700 feet above mean sea level (AMSL) to nearly 850 feet AMSL. The site is surrounded by
wooded and agricultural properties to the northwest, residential properties to the south and southwest, and
residential and wooded properties to the east.
The Phase I landfill is located southwest of the active Phase II landfill and northeast of the active Phase III landfill.
The property also includes an active Type I compost facility located to the east of the Phase I landfill and south of
the Phase II landfill.
1.2 Compliance Monitoring History
Groundwater monitoring at the facility was initiated in 1994. The facility's approved monitoring network for the
Phase I landfill is currently comprised of five groundwater monitoring wells, which monitor the uppermost aquifer
beneath the facility. Monitoring well MW-13 is an upgradient background well for both the Phase I and the
Phase II landfills. Monitoring wells 1-1, 1-2, 1-3, and 1-4 are downgradient compliance wells for the Phase I landfill.
The monitoring well locations are shown on Figure 1. Phase I groundwater samples are analyzed for NC
Appendix I VOCs and the eight RCRA metals semi-annually.
GOLDER
February 22, 2019 1668421.103
The facility's monitoring network also includes five surface water monitoring points, which are shared with the
Phase II landfill. Surface water monitoring points SW-1, SW-2, and SW-3 are upstream monitoring locations and
SW-4 and SW-5 are downstream monitoring locations. Surface water point SW-1 is located along North Buffalo
Creek, west of the facility, along Summit Avenue. Surface water point SW-2 is located west of the facility and
collected from a tributary to North Buffalo Creek that flows from south to north. Surface water point SW-3 is
located west of the facility, downstream of SW-1 and upstream of the confluence of North Buffalo Creek and the
tributary from which SW-2 is sampled. Surface water point SW-4 is located downstream of the facility along North
Buffalo Creek. Surface water point SW-5 is located within the facility's property, at the northern end of the
Phase II landfill off of Rankin Mill Road. The locations of the surface water points are shown on Figure 2. Points
SW-1, SW-2, SW-3, and SW-4 are also shared with the Phase III landfill's monitoring network. Surface water
samples are analyzed for NC Appendix I list of constituents semi-annually.
1.3 Hydrogeologic Setting
The White Street Landfill is located within the Carolina Slate Belt of the Piedmont Physiographic Province of NC
(NCGS, 1985). Generally, the Carolina Slate Belt consists of Late Proterozoic to Cambrian volcanic and
greenschist-facies, metasedimentary rocks intruded by plutonic suites (Butler and Secor, 1991). The site geology
is characterized by a regional -scale felsic intrusive complex, which consists mainly of white to gray, fine- to
coarse -grained, massive to foliated metamorphosed granitic rock. The region is characterized by regional and
small-scale Mesozoic diabase dikes.
The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of saprolite
and partially weathered rock (PWR). Groundwater occurs at depths of approximately 1 to 20 feet below ground
surface. Depth to water measurements, obtained on October 16, 2018, are summarized in Table 1 and were
used to prepare a groundwater surface contour map presented on Figure 1.
As presented, the groundwater flow in the uppermost aquifer beneath the site is generally to the northwest toward
North Buffalo Creek, which is located along the northwestern property boundary of the site. The groundwater
surface contour map and interpreted flow directions are generally consistent with previously submitted
groundwater contour maps and flow directions for this facility.
Based on the October 2018 groundwater surface contour map, the hydraulic gradient in the shallow aquifer
underlying the site, as measured along the conceptual flow paths shown on the contour map, was calculated to be
approximately 0.018 feet/foot. Groundwater velocities were calculated using a hydraulic conductivity of
2.61 X 10-4 centimeters per second (cm/s), which is the average of the hydraulic conductivities calculated for the
hydrogeologic units present at the facility's Phase II and Phase III landfills. This average is based on slug test
data by BPA Environmental & Engineering Inc. (Phase II) and G.N. Richardson & Associates (Phase III).
Although no data is available for the Phase I landfill, it is assumed that the whole facility either share
hydrogeologic units or have similar characteristics (S&ME, 2017). The estimated effective porosity of the shallow
aquifer is expected to range from 0.20 (saprolite) to 0.09 (fractured rock). The effective porosity of saprolite was
used in calculations to provide a conservative estimate of groundwater flow.
Using the above values, the estimated rate of groundwater flow for the uppermost aquifer beneath the facility was
calculated using the following modified Darcy equation:
Vgw = Ki/ne
4 GOLDER
February 22, 2019 1668421.103
where Vgw = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic
gradient, and ne = effective porosity.
The average estimated linear groundwater flow velocity under the waste management unit is approximately 239
feet/year toward the northwest, which is generally consistent with previous estimates (Table 2). The linear
velocity equation above makes the simplified assumptions of a homogeneous and isotropic aquifer. Therefore,
this equation represents a likely average value for the uppermost aquifer and does not account for heterogeneous
and/or anisotropic conditions that may be present in the uppermost aquifer at the facility.
2.0 FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION
Field activities conducted as part of the October 2018 sampling event are discussed in the following sections.
2.1 Visual Inspection Program
In order to detect a potential release at the earliest possible time, the visual inspection program is used at the
Phase I landfill by the sampling personnel. This program includes physical indicators such as potential water
table mounding beneath the waste management unit, physical examination of any stresses in biological
communities, visible signs of Ieachate migration (i.e., Ieachate seeps), unexplained changes in soil
characteristics, and any other change to the environment due to the waste management unit. During the October
2018 compliance monitoring event, no physical indicators of a potential release were observed in the vicinity of
the waste management areas by the sampling personnel.
It should be noted that during periods of heavy precipitation from Hurricane Florence and Hurricane Michael in
September and October 2018 respectively, City of Greensboro employees observed groundwater monitoring
wells 1-2 and 1-4 to be submerged due to localized flooding. Well 1-4 is located in a low-lying area in relatively
close proximity to North Buffalo Creek, while 1-2 is located at the edge of a drainage feature. There are no visible
signs of damage following the storm events.
2.2 Well Network and Groundwater Elevation Measurements
The current network of groundwater monitoring wells at the Phase I landfill consist of one upgradient well
(MW-13) and four downgradient wells (1-1, 1-2, 1-3, and 1-4). Available monitoring well construction information for
the Phase I monitoring wells is summarized on Table 3, and the well locations are shown on Figure 1. The well
locations were selected to yield groundwater samples representative of the conditions in the uppermost aquifer
underlying the facility, and to monitor for potential releases from the landfill unit. Three upstream surface water
monitoring points (SW-1, SW-2, and SW-3) and two downstream surface water monitoring points (SW-4 and
SW-5) are also monitored.
Depth -to -water measurements are recorded to the nearest 0.01 foot prior to initiating groundwater purging and
sampling activities. The respective groundwater level elevations for this event are presented in Table 1. The
historical water level data are also shown on this table. As presented, recent groundwater elevation data for the
monitoring well network indicate that the hydraulic head level in the uppermost aquifer beneath the facility is fairly
consistent, with temporal variation from the long-term average limited to approximately 5 - 20 feet (plus or minus)
under normal conditions.
2.3 October 2018 Monitoring Event
Personnel from Golder visited the facility from October 16 - 19, 2018, to purge and sample monitoring wells and to
sample surface water monitoring points
GOLDER
February 22, 2019 1668421.103
Monitoring wells were purged and sampled using the dedicated pumps at the facility following low -flow micropurge
procedures. Measurements of temperature, pH, specific conductivity, turbidity, dissolved oxygen, and oxidation
reduction potential were recorded on approximately 5-minute intervals, depending on the purge rate. In general,
the purge rate for each well was matched to the yield of the monitoring well, as determined by continuously
monitoring the depth to the water, up to a maximum purge rate of 200 milliliters per minute. Purging was
continued until stabilization was indicated by the water quality parameters.
Prior to sampling, the laboratory -supplied sample containers were prepared. Each sample container was labeled
with the sample identification number, sampling personnel, date and time of sample collection, project name and
number, and requested chemical analyses.
The required groundwater samples were collected directly from the dedicated bladder pump's discharge lines in
the labeled, laboratory -supplied, pre -preserved sample containers after purging was completed based on
stabilization of all water quality parameters. After collection, the samples were placed in a cooler on ice, under
chain -of -custody control. Copies of the sampling logs are presented in Appendix A. Included in each log is a
description of the sampling equipment, sampling method and location, field observations, and water quality
measurements.
The surface water samples were collected directly from the stream, by lowering the sample containers into the
stream flow with the opening facing away from the current flow, taking care to prevent the overflow of the sample
containers and to minimize sample -induced turbidity. However, due to access limitations, SW-3 was collected by
lowering a bailer into the stream from a bridge and then filling the sample containers directly from the bailer.
Measurements of temperature, pH, specific conductivity, turbidity, dissolved oxygen, and oxygen reduction
potential were measured directly from the stream and recorded during the collection of the surface water samples.
After collection, the surface water samples were placed in a cooler on ice, under chain -of -custody control. Copies
of the sampling logs are presented in Appendix A. Included in each log is a description of the sampling
equipment, sampling location, sampling method, field observations, and water quality measurements.
Laboratory Analysis Program
The October 2018 groundwater, surface water, and leachate samples were submitted to Environmental
Conservation Laboratories, Inc. (ENCO) of Cary, NC under chain -of -custody control for analysis. Groundwater
samples were analyzed for NC Appendix I VOCs and RCRA metals. The Phase I and Phase II landfills share
background monitoring well MW-13 and therefore, MW-13 was analyzed for Appendix I inorganic and VOCs plus
mercury. Surface water samples were analyzed for NC Appendix I constituents. Surface water and groundwater
samples were also analyzed for 1,4-dioxane per the May 29, 2018, memorandum from the NC Department of
Environmental Quality (DEQ). The samples were received at the laboratory in good condition and were properly
preserved.
3.0 LABORATORY AND FIELD QA/QC
A laboratory -prepared trip blank accompanied the volatile sample containers to and from the laboratory. ENCO
analyzed the trip blank for NC Appendix I VOCs. Reviews of the laboratory data were performed by Golder
personnel and are included in Appendix B. There were no detections of RCRA metals or NC Appendix I
constituents in the laboratory method blanks and therefore no data qualification was needed.
4.0 DATA EVALUATION
The results of the data evaluations are presented in the following sections.
GOLDER
February 22, 2019 1668421.103
4.1 North Carolina Groundwater and Surface Water Quality Standard
Comparisons
As presented in Table 4, no Resource Conservation and Recovery Act (RCRA) metals were detected above their
respective Practical Quantitation Limits (PQLs) and groundwater standards during the October 2018 event.
During this event, benzene and 1,4-dichlorobenzene were detected above their respective PQLs and NC 2L
Standards in the sample from downgradient well 1-1 as they have been during previous events. The constituent
1,4-dioxane was detected at 1-1, 1-2, 1-3, and 1-4 above the PQL and NC 2L Standard for the first time; however,
this is the first time this analyte has been sampled for and this parameter is not required by regulation or permit.
As shown in Table 6, no NC Appendix I constituents were reported above their respective PQLs and applicable
surface water standards during the October 2018 event. Copper was reported at estimated concentrations below
the PQL, but above the Acute Standard in the samples from upstream monitoring point SW-2 and at estimated
concentrations below the PQL but above the Chronic Standard in the samples from upstream monitoring points
SW-1 and SW-3 and downstream monitoring point SW-5. Because the concentrations are below their respective
PQLs and based on similar concentrations at upstream and downstream samples, the exceedances do not
appear to be related to landfill activities from the facility and no further action is warranted.
5.0 CONCLUSIONS
Based on the results summarized herein, the City of Greensboro will continue monitoring the uppermost aquifer
beneath this facility in accordance with the requirements outlined in NCSWMR 0.600. The next sampling event is
tentatively scheduled for April 2019.

NOTES
1. TOPOGRAPHIC CONTOUR INTERVAL = 10 FEET.
2. GROUNDWATER SURFACE CONTOUR INTERVAL = 2 FEET.
3. GROUNDWATER ELEVATIONS MEASURED ON OCTOBER 16, 2018.
4. GROUNDWATER CONTOURS ARE BASED ON LINEAR INTERPOLATION BETWEEN AND
EXTRAPOLATION FROM KNOWN DATA, TOPOGRAPHIC CONTOURS, AND KNOWN FIELD
CONDITIONS. THEREFORE, GROUNDWATER CONTOURS MAY NOT REFLECT ACTUAL
GROUNDWATER CONDITIONS.
5. GROUNDWATER CONTOUR LINES SHOW THE WATER TABLE SHAPE AND ELEVATION.
THESE CONTOURS ARE INFERRED LINES FOLLOWING THE GROUNDWATER SURFACE
AT A CONSTANT ELEVATION ABOVE SEA LEVEL. THE GROUNDWATER FLOW
DIRECTION IS GENERALLY PERPENDICULAR TO THE GROUNDWATER SURFACE
CONTOURS, SIMILAR TO THE RELATIONSHIP BETWEEN SURFACE WATER FLOW AND
TOPOGRAPHIC CONTOURS.
6. ELEVATIONS SHOWN IN THIS DRAWING ARE IN FEET ABOVE MEAN SEA LEVEL
DATUM ("MEAN SEA LEVEL DATUM" REFERS TO THE NATIONAL GEOTETIC VERTICAL
DATUM (NGVD) OF 1929) AND COORDINATES ARE EXPRESSED IN TERMS OF THE
STATE PLANE COORDINATE SYSTEM.
7. SURFACE WATER LOCATIONS ARE APPROXIMATE.

Dear Dusty Reedy,
Enclosed is a copy of your laboratory report for test samples received by our laboratory on
Thursday, October 18, 2018.
Unless otherwise noted in an attached project narrative, all samples were received in
acceptable condition and processed in accordance with the referenced methods/procedures.
Results for these procedures apply only to the samples as submitted.
The analytical results contained in this report are in compliance with NELAC standards, except
as noted in the project narrative if applicable. This report shall not be reproduced except in
full, without the written approval of the Laboratory.
This report contains only those analyses performed by Environmental Conservation
Laboratories. Unless otherwise noted, all analyses were performed at ENCO Cary. Data from
outside organizations will be reported under separate cover.
If you have any questions or require further information, please do not hesitate to contact me.
Sincerely,
Stephanie Franz

PROJECT NARRATIVE
Date: 31 October 2018
Client: Golder Associates, Inc. (G0007)
Project: White Street LF-Phase 1,11 GW/SW
Lab ID: CB15730
Overview
(� �Eo
www.encolabs.com
Environmental Conservation Laboratories, Inc. (ENCO) analyzed all submitted samples in accordance with the methods
referenced in the laboratory report. Any particular difficulties encountered during sample handling by ENCO are discussed in
the QC Remarks section below.
Quality Control Samples
Bis(2-ethylhexyl)phthalate, a common laboratory contaminant, was detected in the 8270D Method Blank, and the Continuing
Calibration Verification sample (CCV) exhibited a high bias for 2,4-Dinitrophenol, 2-Acetylaminofluorene, 5-Nitro-o-toluidine,
methapyrilene, and Parathion; however, these analytes were not detected in the associated samples, reducing the impact of
the deviation. The CCV exceeded the lower control limits for 3-Nitroaniline; the reported results should be considered
minimum estimates.
The spike recovery of Mercury was outside of control limits for the Post Spike sample. The QC batch was approved based
on acceptable LCS recovery of this element.
The spike recovery of Cyanide was outside of control limits for the MS and MSD samples. The QC batch was approved
based on acceptable LCS recovery of this analyte.
Quality Control Remarks
No Comments
Other Comments
All samples received under this work order arrived in acceptable conditions. The samples were not checked for residual
chlorine, as it is not required.
The analytical data presented in this report are consistent with the methods as referenced in the analytical report. Any
exceptions or deviations are noted in the QC remarks section of this narrative or in the Flags/Notes and Definitions section of
the report.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
J The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
0-01 This compound is a common laboratory contaminant.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.
QM-08 Post -digestion spike did not meet method requirements due to confirmed matrix effects
(dilution test).
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is
ND, there is no impact.
QV-02 The associated continuing calibration verification standard exhibited low bias; the reported
result should be considered to be a minimum estimate.

3.0 LABORATORY QUALITY CONTROL REVIEW
EV Laboratory analyzed at least one internal blank for each method, where applicable.
EV Laboratory blank is interference -free.
Bis(2-ethylhexyl)phthalate, a common laboratory contaminant, was detected in the 8270D Method Blank,
and the Continuing Calibration Verification sample (CCV) exhibited a high bias for 2,4-Dinitrophenol, 2-
Acetylaminofluorene, 5-Nitro-o-toluidine, methapyrilene, and Parathion; however, these analytes were not
detected in the associated samples, reducing the impact of the deviation. The CCV exceeded the lower
control limits for 3-Nitroaniline; the reported results should be considered minimum estimates.
EV Surrogate recoveries are provided for each analytical method, where applicable.
EV Surrogate recoveries for each method are within the acceptable limits (i.e., at least
50% of the surrogates were within range).
EV MS/MSD/LCS data results are provided for each analytical method.
EV MS/MSD/LCS recoveries for each method are within the acceptable limits (i.e., at
least 1 of the 3 were within range).
The spike recovery of Mercury was outside of control limits for the Post Spike sample. The QC batch was
approved based on acceptable LCS recovery of this element. The spike recovery of Cyanide was outside of
control limits for the MS and MSD samples. The QC batch was approved based on acceptable LCS
recovery of this analyte.
4.0 ANALYTE LISTS/METHODS
EV The proper number of constituents are present for each analyte list as identified
above (including detects where applicable).

LABORATORY DATA REVIEW
Page 3 of 3,
EV Proper EPA SW-846 analytical methods were used for analysis.
5.0 DATA REPORTING
EV All analytical reporting associated with the event was performed by the contracted lab
EV Trip, field and/or equipment, and laboratory blank results have all been reported. All
detects for blanks are listed below by constituent. All laboratory method blanks, if any,
have been `flagged' with a `B' where detected in other samples as appropriate and a
laboratory narrative was provided. If the sample was flagged by the laboratory and is
not within 5X of the concentration in the blank (or 1 OX for commonly detected laboratory
contaminants -acetone, methylene chloride and phthalates), list below with explanation
if flags should be removed. If flags need to be added for samples, also list below.
EV It is clear from the laboratory report that samples have or have not been diluted during
analysis, and if the samples have been diluted, the result is reported as a multiple of
the dilution (e.g., a sample diluted 1 Ox resulting in an analytical detection of 1.0 should
be reported as 10). Those that have been diluted are listed below with the dilution
factor.
EV The report provides the reporting limit for each constituent.
EV The results were reported at or below their proper reporting limits (i.e. at or below
standards at MDLs). Those that are not reported correctly are listed below (by
constituent) with the proper reporting limit listed beside them. State if the reporting limit
error is due to dilutions.
EV No inorganic or organic constituents were reported above their respective NC 2L
Drinking Water Standards or Interim Maximum Allowable Concentrations (IMACs) or
surface water standards in wells or field/equipment/trip blanks or above applicable
Surface Water Standards for surface water points.
➢ Cobalt (IMAC = 0.3 ug/L)
• MW-13 @ 4.20 ug/L (J)
➢ Copper (Chronic SW Std = 2.7, acute = 3.6 ug/L)
• SW-5 @ 3.55 ug/L (J)
EV No quantifiable inorganic or organic constituents were detected in a well or surface
water point at concentrations outside of their historical range (more than 5X previous
concentrations or first-time detections).
➢ 1,4 Dioxane was detected for the first time in SW-5. However, this was the
first time this surface water was analyzed for this constituent.

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
J The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
QM-10 LCS/LCSD were analyzed in place of MS/MSD.

detects for blanks are listed below by constituent. All laboratory method blanks, if any,
have been `flagged' with a `B' where detected in other samples as appropriate and a
laboratory narrative was provided. If the sample was flagged by the laboratory and is
not within 5X of the concentration in the blank (or 1 OX for commonly detected laboratory
contaminants -acetone, methylene chloride and phthalates), list below with explanation
if flags should be removed. If flags need to be added for samples, also list below.
EV It is clear from the laboratory report that samples have or have not been diluted during
analysis, and if the samples have been diluted, the result is reported as a multiple of
the dilution (e.g., a sample diluted 1 Ox resulting in an analytical detection of 1.0 should
be reported as 10). Those that have been diluted are listed below with the dilution
factor.
➢ 1,4 Dioxane (10x): 1-1, 1-2, and 1-3
EV The report provides the reporting limit for each constituent.
EV The results were reported at or below their proper reporting limits (e.g., MDLs). Those
that are not reported correctly are listed below (by constituent) with the proper reporting
limit listed beside them. State if the reporting limit error is due to dilutions.
EV No inorganic or organic constituents were reported above their respective NC 2L
Drinking Water Standards or Interim Maximum Allowable Concentrations (IMACs) in

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
J The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
P Greater than 25% concentration difference was observed between the primary and secondary GC column.
The lower concentration is reported.
QM-10 LCS/LCSD were analyzed in place of MS/MSD.
QR-06 The RPD value for the LCS/LCSD was outside of QC acceptance limits.

5.0 DATA REPORTING
EV All analytical reporting associated with the event was performed by the contracted lab.
EV Trip, field and/or equipment, and laboratory blank results have all been reported. All
detects for blanks are listed below by constituent. All laboratory method blanks, if any,
have been `flagged' with a `B' where detected in other samples as appropriate and a
laboratory narrative was provided. If the sample was flagged by the laboratory and is
not within 5X of the concentration in the blank (or 1 OX for commonly detected laboratory
contaminants -acetone, methylene chloride and phthalates), list below with explanation
if flags should be removed. If flags need to be added for samples, also list below.
EV It is clear from the laboratory report that samples have or have not been diluted during
analysis, and if the samples have been diluted, the result is reported as a multiple of
the dilution (e.g., a sample diluted 10x resulting in an analytical detection of 1.0 should
be reported as 10). Those that have been diluted are listed below with the dilution
factor.
EV The report provides the reporting limit for each constituent.
EV The results were reported at or below their proper reporting limits (i.e. at or below
standards, at MDLs). Those that are not reported correctly are listed below (by
constituent) with the proper reporting limit listed beside them. State if the reporting limit
error is due to dilutions.
LCS/LCSD were analyzed in place of the MS/MSD for the 8260C SIM ID analysis. Precision
between duplicate spikes of 1,4-Dioxane exceeded acceptance criteria for the LCS/LCSD.
EV No inorganic or organic constituents were reported above their applicable Surface
Water Standards for surface water points.
Copper (acute = 3.6 ug/L, chronic 2.7 ug/L) — consistent with
historical — all estimated below PQL of 10 ug/L
• SW-1 (3.11 J ug/L)
• SW-2 (3.84 J ug/L)
• SW-3 (2.72 J ug/L)
• SW-5 (3.55 J ug/L)
EV No quantifiable inorganic or organic constituents were detected in a well or surface
water point at concentrations outside of their historical range (more than 5X previous
concentrations or first-time detections).
➢ 1,4 Dioxane was detected for the first time at SW-4 and SW-5. However, this
was the first time surface water was analyzed for this constituent.
