1.0 INTRODUCTION
ATC Associates of North Carolina (ATC) has completed the Remedial Investigation Groundwater
Monitoring and Landfill Gas Monitoring Report for sampling activities at Elon College LDFL
(NONCD0000730) located in Elon, Alamance County, North Carolina. The scope of work includes the tasks
outlined in the Work Plan for Task Orders 730RI-3 and 730RI-4 prepared by ATC and dated December 8,
2023 and approved by the Pre-Regulatory Landfill Unit (“the Unit”) staff on January 23, 2024.
ATC performed the field activities at the site from February 19 through February 21, 2024, which included
the following tasks:
Groundwater samples collected from seven existing monitoring wells (MW-01 through MW-07) and
analyzed for the following:
o Volatile Organic Compounds (VOCs) by SW-846 Method 8260
o 1,4-Dioxane by SW-846 Method 8270SIM
o Semi-Volatile Organic Compounds (SVOCs) by SW-846 Method 8270
o Inorganic hazardous substances by SW-846 Method 6020 (antimony, arsenic, barium,
beryllium, cadmium, chromium, cobalt, copper, lead, manganese, nickel, selenium, silver,
thallium, vanadium, and zinc)
Sample collection from landfill gas probes (LFGP-1 and LFGP-2), and six permanent soil gas
probes (SGP-6, SGP-8, SGP-10 and SGP-11). The probes were also screened using field
instrumentation. Samples collected from the landfill gas probes and the soil gas probes were
analyzed for the following:
o VOCs by Method TO-15
o Hydrogen Sulfide by Method 15/ASTM D5504
o Methane by ASTM D1946
A site map is included in Figure 1. The global positioning satellite (GPS) coordinates of the monitoring
wells, and landfill gas probes are included in Table 1. Field notes, sampling logs, and calibration documents
for all phases of site activities are included in Appendix A. Site photographs are included in Appendix B.
2.0 GROUNDWATER MONITORING
2.1 GROUNDWATER SAMPLING AND RESULTS
ATC gauged groundwater depth at all the monitoring wells and collected samples from each well (MW-01
through MW-07). Depth to groundwater ranged from 2.90 feet bgs (MW-02) to 25.88 feet bgs (MW-5).
Monitoring well construction and depth to groundwater information is summarized on Table 2. A
groundwater contour map is provided as Figure 2. Groundwater flow direction is to the south towards Travis
creek.
Groundwater samples were collected from monitoring wells MW-01 through MW-07. Purging was
performed using a peristaltic pump and Teflon® tubing. Purging and sampling were performed by low-flow
methodology on all wells. A Hanna 98194 water quality meter and flow-through cell were used to monitor
temperature, specific conductivity, pH, and dissolved oxygen (DO) during purging. A Geotech Turbidity
Meter was used to measure turbidity. Prior to conducting the groundwater sampling, ATC calibrated the
water quality meters per the specifications to insure proper calibration. Calibration procedures were
documented in the field as well as information detailing the equipment manufacturer, model number, serial
number, set up parameters, measurement units, and types of calibration gas or fluid used during calibration.
The water quality parameters recorded immediately prior to sampling indicated adequate stabilization. Field
parameter data is included in Table 3. The samples were placed in laboratory-provided containers, properly

Task Order 730RI-4
ATC Project No. PRLU0730W 2 Pre-Regulatory Landfill Unit
labeled, and stored on ice pending delivery to Pace Analytical Services (Pace), a North Carolina accredited
laboratory for analysis by the methods discussed above. The analytical data is summarized in Table 4.
Cumulative Carcinogenic Risk and Non-Carcinogenic Hazard Index values were calculated for all of the
recent groundwater samples and historical groundwater samples using the NCDEQ DWM Risk Calculator
(version February 2024). Groundwater use and groundwater to indoor air exposure pathways were
considered for both residential and non-residential worker land use scenarios. Risk was calculated for
individual sample data and considered only the compounds targeted and detected as described herein. No
modifications to the default parameter values and equations inherent to the NCDEQ DWM Risk Calculator
were made. As specified in N.C.G.S. 130A-310.68, residential and non-residential cumulative risk is
acceptable when the carcinogenic risk is less than 1.0E-04 and the hazard index for systemic toxicants is
less than 1.0. No values exceeded either residential or non-residential. The calculated risk at each
monitoring well is shown on Figure 2 and on Table 4. The laboratory report is included in Appendix C.
Risk calculator output is provided in Appendix D.
3.0 LANDFILL GAS PROBE MONITORING
3.1 LANDFILL GAS PROBE SAMPLING
ATC collected samples from landfill gas probes LFGP-1 and LFGP-2 and from soil-gas probe SGP-6, SGP-
8, SGP-10, and SGP-11. Landfill gas probe locations are shown on Figure 3A and 3B. Soil-gas probes
SGP-7 and SGP-9 were scheduled to be sampled, however, due to shallow groundwater, a sample was
unable to be collected during this sampling event.
To confirm the integrity of the sampling process line, a shut-in test was conducted by applying vacuum
pressure to the lines and observing for vacuum loss at each of the sample locations. The preliminary air
samples were screened with the field helium meter to ensure that less than 10 percent of the helium
concentrations observed within the shroud existed in the preliminary sir sample. Samples were collected
for VOC and methane analysis in batch certified stainless-steel Summa canisters and submitted to Eurofins
Air Toxics LLC in Folsom, California for analysis by the methods described above. Hydrogen sulfide
samples were collected in Tedlar bags. The Tedlar bags were packaged and shipped daily to Air
Technology Laboratories LLC, in City of Industry, California. The laboratory analytical reports are included
in Appendix E. The landfill gas probe analytical data is summarized on Table 6 and are depicted on Figure
3A.
Cumulative Carcinogenic Risk and Non-Carcinogenic Hazard Index values were calculated for all of the
landfill gas samples using the NCDEQ DWM Risk Calculator (version July 2023). Only the soil gas to indoor
air exposure pathway was considered for both residential and non-residential worker land use scenarios.
Risk was calculated for individual sample data and considered only the compounds targeted and detected
as described herein. No modifications to the default parameter values and equations inherent to the
NCDEQ DWM Risk Calculator were made. As specified in N.C.G.S. 130A-310.68, residential and non-
residential cumulative risk is acceptable when the carcinogenic risk is less than 1.0E-04 and the hazard
index for systemic toxicants is less than 1.0. No values exceeded either residential or non-residential. The
calculated risk at each landfill gas probe is shown on Figure 3B. Risk calculator output is provided in
Appendix F.
3.2 LANDFILL GAS PROBE SCREENING
After the samples had been collected, ATC screened landfill gas probes LFGP-1 and LFGP-2 and soil gas
probes SGP-8, SGP-10 and SGP-11. Although ATC was able to collect a sample from SGP-6, water had
entered the sampling line before the screening process. SGP-7 and SGP-9 were also not included in the
screening due to water in the sampling line.

To perform the testing, ATC used a GEM 5000+ (GEM), MiniRAE 3000, and manometer to measure target
landfill gases and other parameters by connecting directly to the Teflon® tubing in each of the soil gas
probes. Soil gas probes gas measurements collected from each location included methane, oxygen, carbon
dioxide, temperature, humidity, barometric pressure, hydrogen sulfide, and VOCs. A manometer was also
used to measure differential pressure.
Prior to conducting the landfill gas survey, ATC calibrated each instrument in the field per the
manufacturer’s specifications and conducted bump tests before, periodically during, and after the landfill
gas survey to insure proper calibration. Calibration procedures were documented in the field as well as
information detailing the equipment manufacturer, model number, serial number, date of factory calibration
and maintenance, set up parameters, measurement units, detection limits, and types of calibration gas and
their expiration dates. In addition, field logs were kept that included the name of the person conducting the
evaluation, a description of weather conditions, and alternate forms of cross-contamination, as well as
hourly ambient temperature, humidity, and barometric pressure readings.
The landfill gas probe screening data is summarized in Table 7. The landfill gas probe screening is also
presented in Figure 3B as comparison between the laboratory results and the screening data.
4.0 QUALITY CONTROL
The following quality control samples were collected:
Duplicate samples– Duplicate samples were collected from all media which included:
groundwater (MW-02), and soil gas (LFGP-2). Both the parent and duplicate readings
depicted similar concentrations for all samples.
Equipment blanks- Equipment blanks (Equipment-Blank-1) was collected by running
deionized water through clean Teflon® tubing directly into sample containers. Barium,
manganese, zinc, and 2-butanone were detected in Equipment-Blank -1 at concentrations
above the method detection limit (MDL), but below the laboratory reported detection limit
(RDL). 2-butanone was not detected within the groundwater samples and is considered to
not be associated with the groundwater sample results. Barium, manganese, and zinc were
detected in the groundwater samples for multiple wells. The resulting concentrations in the
equipment blank constituents are low and therefore are not considered to impact the
groundwater results.
As part of ATC’s quality assurance measures, a data review of the laboratory reports was conducted.
During the review, it was found that the samples were received from the laboratory in acceptable condition
and properly preserved. All samples were analyzed within correct holding times and reported within the lab
report, and the chain of custody was properly completed by all parties. The laboratory method blank for
laboratory report L1707788 dated April 5, 2024, did not detect any compounds above the MDL. Targeted
compounds detected in the duplicate samples were within range for relative percent difference (RPD). Refer
to the laboratory reports in Appendices C and E for details regarding QC results for the laboratory samples
and any noted exceptions.

Notes:
1) ppm = parts per million.
2) LEL = Lower Explosive Limit.
3) μg/mᶟ = Micrograms per Cubic Meter.
4) Hg = Mercury.
5) VOCs = Volatile Organic Compounds.
6) Methane (%LEL) calculated using the following formula: = (% by volume)*(100% LEL) / (5% by volume).
7) Methane (μg/mᶟ) calculated using the following formula: = [(% by volume)*10,000*16.04 / 24.45]*1000 where 16.04 grams/mol is the molecular weight of methane and 24.45 is a conversion factor that
represents the volume of one mole of gas in liters.
8) Hydrogen Sulfide (μg/mᶟ) calculated using the following formula: = [(ppm by volume)*34.08 / 24.45]*1000 where 34.08 grams/mol is the molecular weight of hydrogen Sulfide and 24.45 is a conversion factor that represents the
volume of one mole of gas in liters.
9) * = duplicate reading.
10) BG = Background.

CASE NARRATIVE
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times, unless qualified or notated within
the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples
have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control
are within established criteria except where addressed in this case narrative, a non-conformance form
or properly qualified within the sample results. By my digital signature below, I affirm to the best of my
knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the
quality of the data have been identified by the laboratory, and no information or data have been
knowingly withheld that would affect the quality of the data.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
(S)Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
B The same analyte is found in the associated blank.
C3 The reported concentration is an estimate. The continuing calibration standard associated with this data responded low.
Method sensitivity check is acceptable.
J The identification of the analyte is acceptable; the reported value is an estimate.
J1 Surrogate recovery limits have been exceeded; values are outside upper control limits.
J3 The associated batch QC was outside the established quality control range for precision.
J4 The associated batch QC was outside the established quality control range for accuracy.

LABORATORY NARRATIVE
Modified ASTM D-1946
ATLAS (Formerly ATC Associates)
Workorder# 2402559B
Seven 1 Liter Summa Canister samples were received on February 23, 2024. The laboratory
performed analysis via Modified ASTM Method D-1946 for Methane in air using GC/FID. The
method involves direct injection of 1.0 mL of sample.
Method modifications taken to run these samples are summarized in the table below. Specific project
requirements may over-ride the EATL modifications.
Requirement ATL ModificationsASTM D-1946
Calibration A single point
calibration is performed
using a reference
standard closely
matching the
composition of the
unknown.
A minimum of 5-point calibration curve is performed.
Quantitation is based on average Response Factor.
Reference Standard The composition of any
reference standard must
be known to within
0.01 mol % for any
component.
The standards used by ATL are blended to a >/= 95%
accuracy.
Sample Injection Volume Components whose
concentrations are in
excess of 5 % should
not be analyzed by
using sample volumes
greater than 0.5 mL.
The sample container is connected directly to a fixed
volume sample loop of 1.0 mL on the GC. Linear range is
defined by the calibration curve. Bags are loaded by
vacuum.
Normalization Normalize the mole
percent values by
multiplying each value
by 100 and dividing by
the sum of the original
values. The sum of the
original values should
not differ from 100%
by more than 1.0%.
Results are not normalized. The sum of the reported
values can differ from 100% by as much as 15%, either
due to analytical variability or an unusual sample matrix.
Precision Precision requirements
established at each
concentration level.
Duplicates should agree within 25% RPD for detections >
5 X's the RL.
Receiving Notes
There were no receiving discrepancies.
There were no analytical discrepancies.
