SMARTER ENVIRONMENTAL SOLUTIONS
As requested, Hart & Hickman, PC (H&H) has prepared this letter report to document the
methods and results of additional environmental sampling conducted at the property located at
828 Martin Luther King Jr. Blvd. in Chapel Hill (Site or subject Site). The Site is comprised of
one land parcel that is approximately 10.24 acres in size and contains a two-story approximately
35,000 sq. ft building located in the north -central portion of the Site that is currently used for
police department operations. The Site topography consists of an elevated area where the police
building and associated parking lots are located which slopes along an embankment to the south
to a lower area along Bolin Creek where the Bolin Creek Trail are located. Site topography is
indicated in Figure 1.
Previous assessment activities indicate that the Site was initially used as a borrow pit from the
late 1950s to early 1960s, and then was used as a fill site from the mid-1960s to the mid-1970s.
It appears that the fill initially consisted of construction debris, and then coal combustion
products (CCPs) were placed above the construction debris for structural fill. Previous
environmental assessment activities were conducted from 2013 to 2017 which culminated in the
completion of a Phase II Remedial Investigation (RI) Report for the Site dated August 14, 2017.

Additional background information and the results of previous assessment activities are provided
in the Phase II RI Report. The results of previous assessment activities are also summarized in
the attached summary tables.
The Town of Chapel Hill recently contracted Duncklee & Dunham (D&D) and Dr. Ken Rudo of
Rudo Toxicological Consultants (Rudo) to complete a Human Health and Ecological Risk
Assessment for the subject Site. Prior to performing the Human Health and Ecological Risk
Assessment, D&D and Rudo identified certain data gaps and requested that additional
assessment be completed to support the risk assessment activities. H&H performed the
assessment activities in April 2019 which included 1) collection and analysis of an updated
round of groundwater samples from the existing monitor well network, 2) soil and CCP sampling
consisting of the collection and analysis of samples from previous sample locations as well as
additional sample locations, 3) collection and analysis of sediment and surface water samples
from previous and additional sample locations in Bolin Creek, and 4) collection of indoor air
samples from the police department building to screen the Site for potential radiological
concerns. A brief description of the methods and results of the data gap assessment activities are
provided below.
2.0 Scope of Work
H&H performed the additional assessment activities on April 3 through 8, 2019. The
assessment activities were performed in general accordance with the North Carolina Department
of Environmental Quality's (DEQ's) Inactive Hazardous Sites Branch (IHSB) Guidelines for
Assessment and Cleanup (Guidelines) and most recent versions of the U.S. Environmental
Protection Agency (EPA) Region IV Science and Ecosystem Support Division (SESD) Field
Branches Quality System and Technical Procedures.
Prior to conducting the assessment activities, H&H contacted North Carolina 811 One -Call, the
public utility locator service, to mark subsurface utilities at the site. After collection, sample

locations (other than the existing surveyed monitor wells) were estimated using a sub -meter
global positioning system (GPS) unit.
The locations of the previous and recent samples are provided in Figure 1 (groundwater, soil,
sediment, and surface water), and the locations of the indoor air samples are indicated in Figure
2. In Figure 1, the locations where H&H collected samples in April 2019 are highlighted in
yellow for ease of reference.
2.1 Monitoring Well Sampling Activities
H&H collected groundwater samples from existing monitoring wells MW-1, MW-3A, MW-4A,
MW-6, and MW-7 on April 4, 2019. Before sampling, the monitoring wells were gauged for
depth to water. The wells were then be purged to ensure that water samples obtained from the
wells were representative of the aquifer. Purging and sampling of the monitoring wells were
completed using low flow/low stress method in general accordance with EPA Region IV SESD
protocol. Monitor wells MW-3A, MW-4A, and MW-6 were purged and sampled using a
peristaltic pump with new polyethylene tubing. Due to depths to water greater than 25 ft,
monitor wells MW-1 and MW-7 were purged and sampled using decontaminated bladder pumps
connected to new polyethylene tubing.
During purging, field measurements of pH, temperature, dissolved oxygen, oxidation reduction
potential, turbidity, and conductivity were collected at 3 to 5-minute intervals. Purging was
considered complete when water quality parameters stabilized (i.e., pH f 0.1 SU, conductivity
varies no more than 5%, and turbidity is less than 10 Nephelometric Turbidity Units [NTUs]).
H&H was able to obtain samples with turbidity less than 10 NTU at each monitor well. The low
flow groundwater sampling records are provided in Appendix A.

H&H conducted the soil sampling activities on April 3 and 5, 2019. H&H advanced eight soil
borings in the following locations using a decontaminated stainless -steel hand auger:
• H&H collected additional background samples at borings BG-6, BG-7, and BG-8 in
an area located west of Martin Luther King, Jr. Blvd. At each location, samples were
collected for laboratory analysis at depths of 0-1 ft and 2-3 ft below ground surface
(bgs).
• H&H collected samples of CCP at previous sample locations GP-5 and GP-6.
Samples were collected for laboratory analysis at the same approximate depths as
samples collected from the borings in 2014 (4-6 ft bgs at GP-5 and 10-12 ft bgs at
GP-6).
• H&H collected sample HH-9 at a depth of 0-1 ft bgs from the western portion of the
embankment where CCP is under 2 ft of cover.
• H&H collected samples HH-10 and HH-I I at a depth of 0-1 ft bgs from the eastern
portion of the embankment where exposed CCP is present at the surface.
In addition, H&H collected soil samples from identified potential wet weather drainage pathways
in the lower portion of the Site between the embankment and Bolin Creek. The locations of
these samples, labeled SED-8, SED-9, and SED-I I through SED-21, are indicated in Figure 1.
Samples at these locations were collected at depths of 2 to 6 inches bgs. Sample SED-10 was
collected from a location on the south stream embankment of Bolin Creek (other side of Bolin
Creek from Site) at a depth of 2-6 inches. In addition, samples SED-3A and SED-5A were
collected at a depth of 0-1 ft bgs from the northern embankment of Bolin Creek just north of in -
stream sediment samples SED-3 and SED-5 for comparison between embankment and adjacent
in -stream sample concentrations.
At the desired sampling interval, soil and CCP samples for laboratory analysis were collected
from the center of the decontaminated hand auger bucket at each boring and then placed into
laboratory containers for analysis.

2.3 Surface Water and Sediment Sampling Activities
H&H collected seven co -located in -stream sediment and surface water samples from Bolin Creek
on April 4 and 5, 2019. Samples SW-1/SED-1 through SW-5/SED-5 were collected in the same
locations as samples with the same identifications collected in November 2016 as part of the
Phase II RI. Samples SW-6/SED-6 and SW-7/SED-7 were collected downstream of the Site and
downstream of sample location SW-5/SED-5. Samples SW-1/SED-1 and SW-2/SED-2 served
as background samples and were collected west of Martin Luther King, Jr. Blvd.
Samples were collected from downstream locations moving to upstream locations. Surface
water and sediment samples SW-5/SED-5, SW-6/SED-6, and SW-7/SED-6 were collected on
April 4, and the remainder of the samples were collected on April 5. The samples were collected
under baseflow conditions prior to rain which occurred on April 5. On April 5, rain began to fall
mid -morning after the collection of the surface water and sediment samples. During the rain
event (which total approximately 0.75 inch of rain according to National Weather Service
records), H&H observed the Site for stormwater runoff in the potential drainage channels in the
lower portion of the Site. Stormwater runoff was only identified in the far southeastern portion
of the Site at location SW-21 just downgradient of a culvert that extends below the Bolin Creek
Trail (see Figure 1). Therefore, a water sample was collected at this location for analysis.
Because of the presence of elevated turbidity in the sample, a filtered and unfiltered sample were
collected for analysis at SW-21.
H&H collected the surface water samples by placing the sample bottles directly into the flowing
stream and allowing the bottles to fill with water. During sampling at each location, H&H
utilized water quality meters to collect measurements of pH, temperature, dissolved oxygen,
turbidity, and specific conductivity. H&H collected the sediment samples with a decontaminated
stainless -steel scoop from areas of observed sediment accumulation. Please note that the bottom
of the Bolin Creek near the Site is primarily comprised of large gravel and boulders with small
pockets of sand -sized and finer sediment. The sediment samples were collected from these small

pockets of accumulated smaller -sized sediment; no gravel or boulders were included in the
samples for laboratory analysis.
2.4 Groundwater, Soil Surface Water, and Sediment Laboratory Analyses
Based upon previous analytical data, the groundwater, soil, surface water, and sediment samples
were analyzed for the metals arsenic, barium, beryllium, cadmium, total chromium, cobalt,
copper, manganese, nickel, and selenium by EPA Methods 6020/7470/7471 and strontium by
EPA Method 6010. In addition, the soil and sediment samples were analyzed for hexavalent
chromium by EPA Method 7199. Surface water samples were also analyzed for hardness by
Standard Method 2340B to calculate North Carolina surface water standards for metals which
are hardness dependent.
Upon collection, samples were placed directly into laboratory -supplied sample containers. After
sample collection, sample containers were sealed, labeled, placed into a laboratory -supplied
sample cooler, and covered with ice. The coolers were then delivered under standard chain -of -
custody protocols to Pace Analytical Services.
2.5 Indoor Air Radon Sampling Activities
To screen the Site for potential radionuclides, H&H deployed five indoor air radon sampling
canisters in representative sample locations in the first floor of the Police Department building.
H&H collected the radon samples using a charcoal -type radon test kits which were deployed on
April 5, 2019 and collected on April 8, 2019 (approximate sample period of 73.5 hours at each
location). Following the sampling period, the test kits were sealed and sent to AccuStar
laboratory for analysis of radon by EPA Method #402-R-92-004. The locations of the samples
are indicated in Figure 2.
2.6 Quality Assurance/Quality Control (QA/QC)

In addition to standard analytical method QA/QC procedures performed by the laboratory, H&H
conducted the following activities for QA/QC evaluation purposes:
• Non -dedicated equipment and tools were decontaminated prior to use at each boring or
sampling location, or following exposure to soil, sediment, groundwater, or surface
water.
• A duplicate indoor air sample was collected for radon analysis to evaluate data
reproducibility. The duplicate sample was collected in the First Floor Administrative
Office.
• Duplicate soil, groundwater, surface water, and sediment samples were collected to
evaluate data reproducibility. The duplicate sample were collected at GP-6 (CCP), MW-
6 (groundwater), SW-4 (surface water), and SED-2 (sediment).
• Equipment/field blanks were collected by passing laboratory supplied deionized water
through decontaminated equipment prior to use and then collecting the water for analysis
of metals. The groundwater sample rinse blank was collected by pouring the water
through the peristaltic pump tubing (sample labeled RB-MW), the soil and sediment rinse
blanks were collected by pouring water over a decontaminated hand auger or scoop
(samples labeled RB-Soil and RB-SED), and the surface water rinse sample was
collected by pouring water in a laboratory supplied unpreserved container (sample
labeled RB-SW).

3.0 Results Summary
The results of analysis of the data gap samples are summarized in Tables 1 through 8 along with
the historical analytical data. In the tables, the April 2019 sample dates are highlighted in yellow
for ease in referencing the additional data. The laboratory analytical data is provided in
Appendix B. Some brief observations concerning the data and are provided in the following
sections.
3.1 Groundwater Analytical Data
A summary of the monitor well construction and groundwater elevation data are provided in
Table 1, a summary of the groundwater analytical data is provided in Table 3, and a summary of
groundwater field geochemical parameters is provided in Table 4. In Table 3, groundwater
analytical data are compared to background (MW-5) and the North Carolina 2L groundwater
standards.
Some brief observations concerning the data are provided below:
• Groundwater elevations were approximately 2 to 5 ft higher than in November 2016.
This is expected considering the large amount of rainfall that occurred in 2018 and early
2019 prior to the April 2019 monitoring event.
• Groundwater flow direction is to the southeast consistent with previous data.
• Groundwater metals concentrations for the downgradient and cross -gradient wells (MW-
3A, MW-4A, MW-6, and MW-7) were generally similar to the previous sampling event
in November 2016. Overall concentration decreases were observed in the furthest
downgradient well MW-4A. In MW-1, arsenic, barium and strontium increased in
concentration, but manganese and cobalt decreased. Of the metals analyzed in the April
2019 sampling event, arsenic, barium, cobalt, and manganese in MW-1, selenium in
MW-3A, and manganese in MW-6 exceeded background and 2L standards.
3.2 Soil/CCP Analytical Data

The soil and CCP analytical data are summarized in Table 2. The data in Table 2 are compared
to Site -specific background sample concentrations and DEQ's Preliminary Soil Remediation
Goals (PSRGs). Note that the range of soil background concentrations and the 95% Upper
Confidence Level (UCL) of the mean of the background data are provided in Table 2 and have
been updated from the values included in the Phase II RI Report based upon the results of
analysis of the additional background samples collected in April 2019.
Some brief observations concerning the data are provided below:
The additional background samples (BG-6, BG-7, and BG-8) indicated similar
concentrations to the previous background samples, although a relatively higher
concentration of hexavalent chromium (5.34 mg/kg) was detected in background sample
BG-6 (0-1 ft) as compared to previous samples.
Metals concentrations in CCP samples (GP-5, GP-6, HH-10, and HH-11) were similar to
previous samples, with arsenic being the primary metal detected. At GP-5 and GP-6
where samples were collected previously in 2014 at similar depths, metals concentrations
were generally similar in GP-5 and lower in GP-6 as compared to the previous sample
analyses.
• Consistent with previous data from the erosional CCP areas, the drainage pathway
samples collected from the areas near where erosional CCP is present indicated elevated
levels of arsenic and barium (SED-11, SED-13, SED-15, SED-16, and SED-17) although
at lower concentrations than the samples of CCP. Drainage pathway samples located
away from the erosional CCP areas generally did not indicate significantly elevated
metals or only slightly elevated metals (SED-3A, SED-5A, SED-8, SED-9, SED-12,
SED-14, SED-18, SED-19, SED-20, SED-21). Consistent with most samples located
away from areas of erosional CCP, sample SED-10, located on the south side of Bolin
Creek, did not indicate elevated concentrations of metals.

The surface water analytical data are summarized in Table 5, and the surface water geochemical
parameter data are summarized in Table 6. The data in Table 5 are compared to Site -specific
background sample concentrations from SW-1 and SW-2, the DEQ 2B surface water standards,
and the EPA Region 4 surface water screening criteria (chronic). Note that for some metals, the
2B surface water standard is hardness dependent. For metals which the surface water standard is
hardness dependent, the 2B surface water standards were calculated using the mean hardness
value of samples SW-1 through SW-7 of approximately 54.5 mg/l.
Some brief observations concerning the data are provided below:
• Similar to the previous sampling event, the downstream sample concentrations were
generally consistent with background levels. As before, there was a potentially slightly
elevated level of manganese at the SW-3 location, although the concentration was less
than the surface water standard. Copper was also potentially elevated in SW-3 but was
also less than the surface water standard.
• During rainfall, the only location where we identified water flowing in the low area near
Bolin Creek Trail was at SW-21 which is in the far southeastern portion of site where a
culvert crosses under Bolin Creek Trail. Metals concentrations at SW-21 were similar to
those in SW-3 with potentially slightly elevated levels of manganese and copper below
the 2B surface water standard.
3.4 Sediment Analytical Data
The in -stream sediment analytical data are summarized in Table 7. The data in Table 7 are
compared to Site -specific background sample concentrations from samples SED-1 and SED-2,
the range and 95% UCL of the mean of background soil sample concentrations, the PSRGs, and
the EPA Region 4 sediment screening criteria.

Some brief observations concerning the data are provided below:
• Sediment concentrations were generally consistent with background.
• The manganese concentration at SW-5, which appeared elevated in the November 2016
sampling, was consistent with background levels in the April 2019 sampling event.
• Strontium appears slightly elevated at SED-4 as compared to the previous sampling event
and background sediment, although the concentration is consistent with background soil
data. The strontium concentration is significantly below the PSRGs.
3.5 Radon Analytical Data
The results of analysis of the radon samples collected from the first floor of the police station are
summarized in Table 8. In Table 8, the data are compared to the EPA radon action level of 4
pCi/L.
The results of the radon sample analyses indicate that radon was not detected in three of the five
samples, and was detected at the detection limit of 0.4 pCi/L in two of the samples. The detected
concentrations are well below the EPA action level.
3.6 QA/QC Sample Summary
A brief summary of the QA/QC sample analyses is provided below:
• The results of analysis of the duplicate samples indicated generally good correlation with
the parent sample, except for the duplicate sediment sample collected at SED-2 where
there were some differences in metals concentrations between the two samples. This is
likely the result of sample heterogeneity.
• The results of analysis of the rinse blank samples indicated the presence of trace levels
(less than 1 µg/1) of the metals arsenic, barium, chromium, copper, manganese, nickel,
and or strontium in one or more samples. Given the trace levels detected of these metals
in comparison to the sample concentrations detected and/or screening levels/standards,
the concentrations of the metals in the rinse blanks are not expected to have a significant
effect on interpretation of the data.

Summary of Soil Analytical Data
828 Martin Luther King, Jr. Blvd.
Chapel Hill, North Carolina
H&H Job No. TCH-003
Notes:
Yellow highlighting indicates samples collected as part of April 2019 data gap sampling
Soil concentrations are reported in milligrams per kilogram (mg/kg).
PSRG = North Carolina Department of Environmental Quality (DEQ) Preliminary Soil Remediation Goals (PSRGs) (February 2018); UCL = Upper Confidence Limit
95% UCL of site specific background ranges were calculated using EPA ProUCL 5.1
North Carolina Soil Background Range taken from Elements in North American Soils, 2nd Edition by James Dragun and Khaled Chekiri
"Not available for North Carolina. Used Eastern US Background Range
Bold denotes concentration above protection of groundwater PSRG and significantly above background.
Shading indicates concentration above residential PSRG and significantly above background.
Underlining indicates concentration above industrial PSRG and significantly above background.
ND = Not Detected; NA = Not Analyzed; NS = Not Specified; -- = statistical test not applicable to data set
J = Detected above method detection limit but below laboratory reporting limit; therefore, result is an estimated concentration
01 = Analyte failed the method required serial dilution test and/or subsequent post -spike criteria. These failures indicate matrix interference.
J6 = The sample matrix interfered with the ability to make any accurate determination; spike value is low.
BH = Method blank greater than one-half laboratory reporting limit, but sample concentration greater than 1 Ox the method blank.
A = Continuing Calibration Verification standard recovery (82%) is less than the lower control limit (90%). Result has possible low bias.
' denotes duplicate sample taken
2 95% UCL of Site Specific Background Values were calculated using values from samples collected through the Phase II RI
Analytical Methods
Metals by EPA Method 6010C or 6020B
Hexavalent Chromium by EPA Method 7196 or 7199 (Phase II RI and April 2019 Data Gap Samples)
Mercury by EPA Method 7471 B

Yellow highlighting indicates samples collected as part of April 2019 data gap sampling
All results in ug/I, except turbidity which is NTUs
2L Standard = North Carolina Department of Environmental Quality (DEQ) 15A NCAC 02L.0202 Groundwater Standards (April 2013).
IMAC = Interim Maximum Allowable Concentration
Bold denotes above the 2L standard or IMAC and background levels
ND = Not Detected; NA = Not Analyzed; NS = Not Specified
J = Detected above method detection limit but below laboratory reporting limit; therefore, result is an estimated concentration
U = Below method detection limit
*reported to the method detection limit instead of laboratory reporting limit
Denotes sample labeled as "Well #1" in the lab report associated with the Limited Phase II ESA prepared by Falcon
2 Denotes duplicate sample taken.
3 Denotes sample labeled as "Well 1" in the lab report associated with the October 3, 2014 letter prepared by Falcon
4 Denotes filtered samples
5 An unfiltered sample was also collected from MW-4 on August 20, 2014 and the results were reported in mg/kg-wet, presumably because of the high sediment load. These data are not included in this table.
Analytical Methods:

Sediment concentrations are reported in milligrams per kilogram (mg/kg).
denotes duplicate sample taken
2 EPA Region 4 Ecological Screening Value from EPA (2018)
3 95% UCL of Site Specific Background Values were calculated using values from samples collected through the Phase II RI
PSRG = North Carolina Department of Environmental Quality (DEQ) Preliminary Soil Remediation Goals (PSRGs) (February 2018); UCL = Upper Confidence Limit
ND - Not Detected; NA - Not Analyzed; NS - Not Specified
J = Detected above method detection limit but below laboratory reporting limit; therefore, result is an estimated concentration.
B = Analyte is found in the associated blank.
01 = Analyte failed the method required serial dilution test and/or subsequent post -spike criteria. These failures indicate matrix interference.
J3 = The associated batch QC was outside the established quality control range for precision.
J6 = The sample matrix interfered with the ability to make any accurate determination; spike value is low.
Bold denotes concentration above protection of groundwater PSRG and significantly above background.
Underlining indicates concentration above industrial PSRG and significantly above background.
Analytical Methods:
Metals by EPA Method 6010C, 6020A, or 6020B
Mercury by EPA Method 7470A
Hexavalent Chromium by EPA Method 7199A

CASE NARRATIVE
ONE LAB. NATIONWIDE.
FP1
Unless qualified or notated within the narrative below, all sample aliquots were received at the correct
temperature, in the proper containers, with the appropriate preservatives, and within method specified
holding times. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental
FTC
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
FSS
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
ONE LAB. NATIONWIDE.
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.
Abbreviations and Definitions
(dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry) Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry) Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG
Sample Delivery Group.
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.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
Dilution
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.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
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.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
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.
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"
Result
(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.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
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
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
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.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
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.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
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.
E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial
calibration (ICAL).
J The identification of the analyte is acceptable; the reported value is an estimate.
J3 The associated batch QC was outside the established quality control range for precision.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
01 The analyte failed the method required serial dilution test and/or subsequent post -spike criteria. These failures indicate
matrix interference.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
Unless qualified or notated within the narrative below, all sample aliquots were received at the correct
temperature, in the proper containers, with the appropriate preservatives, and within method specified
holding times. 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
ONE LAB. NATIONWIDE.
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.
Abbreviations and Definitions
(dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry) Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry) Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG
Sample Delivery Group.
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.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
Dilution
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.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
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.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
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.
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"
Result
(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.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
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
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
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.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
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.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
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
J
The identification of the analyte is acceptable; the reported value is an estimate.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
FP1
Unless qualified or notated within the narrative below, all sample aliquots were received at the correct
temperature, in the proper containers, with the appropriate preservatives, and within method specified
holding times. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental
FTC
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
FSS
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
ONE LAB. NATIONWIDE.
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.
Abbreviations and Definitions
(dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry) Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry) Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG
Sample Delivery Group.
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.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
Dilution
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.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
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.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
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.
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"
Result
(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.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
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
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
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.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
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.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
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
E
The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial
calibration (ICAL).
J
The identification of the analyte is acceptable; the reported value is an estimate.
J6
The sample matrix interfered with the ability to make any accurate determination; spike value is low.
01
The analyte failed the method required serial dilution test and/or subsequent post -spike criteria. These failures indicate
matrix interference.

CASE NARRATIVE
ONE LAB. NATIONWIDE.
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
ONE LAB. NATIONWIDE.
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.
Abbreviations and Definitions
(dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].
MDL Method Detection Limit.
MDL (dry) Method Detection Limit.
RDL Reported Detection Limit.
RDL (dry) Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG
Sample Delivery Group.
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.
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
Dilution
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.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
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.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
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.
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"
Result
(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.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
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
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
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.
This is the document created in the field when your samples were initially collected. This is used to verify the time and
Sample Chain of
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
Custody (Sc)
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.
This section of your report will provide the results of all testing performed on your samples. These results are provided
Sample Results (Sr)
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
J
The identification of the analyte is acceptable; the reported value is an estimate.
J6
The sample matrix interfered with the ability to make any accurate determination; spike value is low.
