Case Narrative
The samples were received in accordance with the Chain of Custody and no significant deviations were encountered during the preparation
or analysis unless otherwise noted. Sample Receipt, Container Information, and the Chain of Custody are located at the back of the report.
Results contained within this report relate only to the samples submitted under this Alpha Lab Number and meet NELAP requirements for all
NELAP accredited parameters unless otherwise noted in the following narrative. The data presented in this report is organized by parameter
(i.e. VOC, SVOC, etc.). Sample specific Quality Control data (i.e. Surrogate Spike Recovery) is reported at the end of the target analyte list
for each individual sample, followed by the Laboratory Batch Quality Control at the end of each parameter. Tentatively Identified
Compounds (TICs), if requested, are reported for compounds identified to be present and are not part of the method/program Target
Compound List, even if only a subset of the TCL are being reported. If a sample was re -analyzed or re -extracted due to a required quality
control corrective action and if both sets of data are reported, the Laboratory ID of the re -analysis or re -extraction is designated with an "R"
or "RE", respectively.
When multiple Batch Quality Control elements are reported (e.g. more than one LCS), the associated samples for each element are noted in
the grey shaded header line of each data table. Any Laboratory Batch, Sample Specific % recovery or RPD value that is outside the listed
Acceptance Criteria is bolded in the report. In reference to questions H (CAM) or 4 (RCP) when "NO" is checked, the performance criteria
for CAM and RCP methods allow for some quality control failures to occur and still be within method compliance. In these instances, the
specific failure is not narrated but noted in the associated QC Outlier Summary Report, located directly after the Case Narrative. QC
information is also incorporated in the Data Usability Assessment table (Format 11) of our Data Merger tool, where it can be reviewed in
conjunction with the sample result, associated regulatory criteria and any associated data usability implications.
Soil/sediments, solids and tissues are reported on a dry weight basis unless otherwise noted. Definitions of all data qualifiers and acronyms
used in this report are provided in the Glossary located at the back of the report.
HOLD POLICY - For samples submitted on hold, Alpha's policy is to hold samples (with the exception of Air canisters) free of charge for 21
calendar days from the date the project is completed. After 21 calendar days, we will dispose of all samples submitted including those put
on hold unless you have contacted your Alpha Project Manager and made arrangements for Alpha to continue to hold the samples. Air
canisters will be disposed after 3 business days from the date the project is completed.
Please contact Project Management at 800-624-9220 with any questions.

Case Narrative (continued)
Volatile Organics in Air
Canisters were released from the laboratory on June 8, 2020. The canister certification results are provided as
an addendum.
L2027078-01 through -07: Prior to sample analysis, the canisters were pressurized with UHP Nitrogen due to
canister size. The pressurization resulted in a dilution of the sample. The reporting limits have been elevated
accordingly.
I, the undersigned, attest under the pains and penalties of perjury that, to the best of my knowledge and
belief and based upon my personal inquiry of those responsible for providing the information contained
in this analytical report, such information is accurate and complete. This certificate of analysis is not
complete unless this page accompanies any and all pages of this report.

GLOSSARY
Acronyms
DL Detection Limit: This value represents the level to which target analyte concentrations are reported as estimated values, when
those target analyte concentrations are quantified below the limit of quantitation (LOQ). The DL includes any adjustments
from dilutions, concentrations or moisture content, where applicable. (DoD report formats only.)
EDL Estimated Detection Limit: This value represents the level to which target analyte concentrations are reported as estimated
values, when those target analyte concentrations are quantified below the reporting limit (RL). The EDL includes any
adjustments from dilutions, concentrations or moisture content, where applicable. The use of EDLs is specific to the analysis
of PAHs using Solid -Phase Microextraction (SPME).
EMPC Estimated Maximum Possible Concentration: The concentration that results from the signal present at the retention time of an
analyte when the ions meet all of the identification criteria except the ion abundance ratio criteria. An EMPC is a worst -case
estimate of the concentration.

Data Qualifiers
A Spectra identified as "Aldol Condensates" are byproducts of the extraction/concentration procedures when acetone is introduced in
the process.
B The analyte was detected above the reporting limit in the associated method blank. Flag only applies to associated field samples that
have detectable concentrations of the analyte at less than ten times (I Ox) the concentration found in the blank. For MCP -related
projects, flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (I Ox)
the concentration found in the blank. For DOD -related projects, flag only applies to associated field samples that have detectable
concentrations of the analyte at less than ten times (1 Ox) the concentration found in the blank AND the analyte was detected above
one-half the reporting limit (or above the reporting limit for common lab contaminants) in the associated method blank. For NJ -
Air -related projects, flag only applies to associated field samples that have detectable concentrations of the analyte above the
reporting limit. For NJ -related projects (excluding Air), flag only applies to associated field samples that have detectable
concentrations of the analyte, which was detected above the reporting limit in the associated method blank or above five times the
reporting limit for common lab contaminants (Phthalates, Acetone, Methylene Chloride, 2-Butanone).
C Co -elution: The target analyte co -elutes with a known lab standard (i.e. surrogate, internal standards, etc.) for co -extracted
analyses.
D Concentration of analyte was quantified from diluted analysis. Flag only applies to field samples that have detectable concentrations
of the analyte.
E Concentration of analyte exceeds the range of the calibration curve and/or linear range of the instrument.
G The concentration may be biased high due to matrix interferences (i.e, co -elution) with non -target compound(s). The result should
be considered estimated.
H The analysis of pH was performed beyond the regulatory -required holding time of 15 minutes from the time of sample collection.
I The lower value for the two columns has been reported due to obvious interference.
J Estimated value. This represents an estimated concentration for Tentatively Identified Compounds (TICs).
M Reporting Limit (RL) exceeds the MCP CAM Reporting Limit for this analyte.
ND Not detected at the reporting limit (RL) for the sample.
NJ Presumptive evidence of compound. This represents an estimated concentration for Tentatively Identified Compounds (TICS), where
the identification is based on a mass spectral library search.
P The RPD between the results for the two columns exceeds the method -specified criteria.
Q The quality control sample exceeds the associated acceptance criteria. For DOD -related projects, LCS and/or Continuing Calibration
Standard exceedences are also qualified on all associated sample results. Note: This flag is not applicable for matrix spike recoveries
when the sample concentration is greater than 4x the spike added or for batch duplicate RPD when the sample concentrations are less
