Dear Mary Brewer:
Waypoint Analytical Virginia, Inc. received sample(s) on 1/20/2022 for the analyses presented in the following
report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method. Sub -contracted testing is noted on the Sample Summary Table
if applicable.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters (NELAP and non-NELAP) were performed in accordance with guidelines established by the USEPA
(including 40 CFR 136 Method Update Rule May 2012) and NELAC unless otherwise indicated.
Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time
Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as -
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report.
Please do not hesitate to contact me or client services if you have any questions or need additional information
Sincerely,
�aw,'c MC G19"./

Case Narrative
Synagro
Lot Number: XD22055
This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report. Where
sampling is conducted by the client, results relate to the accuracy of the information provided, and as the
samples are received.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace")
Laboratory Quality Manual, standard operating procedures (SOPs), and Pace policies. Any exceptions to
the TNI standards, the Laboratory Quality Manual, SOPs or policies are qualified on the results page or
discussed below.
Pace is a TNI accredited laboratory; however, the following analyses are currently not listed on our TNI
scope of accreditation: Drinking Water: VOC (excluding BTEX, MTBE, Naphthalene, & 1,2-
dichloroethane) EPA 524.2, E. coli and Total coliforms SM 9223 B-2004, Solid Chemical Material: TOC
Walkley-Black, Biological Tissue: All, Non -Potable Water: SGT-HEM EPA 1664B, Silica EPA 200.7,
Boron, Calcium, Silicon, Strontium EPA 200.8, Bicarbonate, Carbonate, and Hydroxide Alkalinity SM 2320
B-2011, SM 9221 C E-2006 & SM 9222D-2006, Strontium SW-846 6010D, VOC SM 6200 B-2011, Fecal
Coliform Colilert-18.
Where applicable, all soil sample results (including LOQ and DL if requested) are corrected for dry weight
unless flagged with a "W" qualifier.
If you have any questions regarding this report, please contact the Pace Project Manager listed on the
cover page.
The pH analysis associated with the sample(s) in this report was/were performed after the method
recommended 15 minute holding time.
Inorganic Metals
The following sample was classified as biosolids therefore in order to maintain proper digestion they were
weighed out between 3.0-4.0 grams: XD22055-001. The LOQ has been adjusted accordingly.
Inorganic Non -Metals
The solid Nitrate LOQ standard analyzed during the analytical run did not pass criteria. The aqueous
standard analyzed did meet criteria.
Run 1 analyses are associated to an LCS that was misspiked due to a preparation error with the LCS
spiking solution. Run 2 analyses were outside of holding time and are associated to a solid LOQ that did
not recover or pass criteria. All other associated QC are passing.

Dear Mary Brewer:
Waypoint Analytical Virginia, Inc. received sample(s) on 10/10/2022 for the analyses presented in the following
report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method. Sub -contracted testing is noted on the Sample Summary Table
if applicable.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters (NELAP and non-NELAP) were performed in accordance with guidelines established by the USEPA
(including 40 CFR 136 Method Update Rule May 2012) and NELAC unless otherwise indicated.
Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time
Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as -
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report.
Please do not hesitate to contact me or client services if you have any questions or need additional information
Sincerely,
�aw,'c MC G19"./
Pauric McGroary
Agronomist
Laboratory's liability in any claim relating to analyses performed shall be limited to, at laboratory's option, repeating the
analysis in question at laboratory's expense, or the refund of the charges paid for performance of said analysis.

WorkOrder Narrative:
21121829: This report in its entirety consists of the following documents: Cover Letter, Case Narrative,
Analytical Results, QC Summary Report, Applicable Accreditation Information, Chain -of -Custody,
Cooler Receipt Form, and other applicable forms as necessary. All documents contain the Summit
Environmental Technologies, Inc., Work Order Number assigned to this report.
Summit Environmental Technologies, Inc., holds the accreditations/certifications listed at the bottom of
the cover letter that may or may not pertain to this report. Please refer to the "Accreditation Program
Analytes Report" for accredited analytes list.
The information contained in this analytical report is the sole property of Summit Environmental
Technologies, Inc. and that of the customer. It cannot be reproduced in any form without the consent of
Summit Environmental Technologies, Inc. or the customer for which this report was issued. The results
contained in this report are only representative of the samples received. Conditions can vary at different
times and at different sampling conditions. Summit Environmental Technologies, Inc. is not responsible
for use or interpretation of the data included herein.
All results for Solid Samples are reported on an "as received" or "wet weight" basis unless indicated as
"dry weight" using the "-dry" designation on the reporting units.
This report is believed to meet all of the requirements of the accrediting agency, where applicable. Any
comments or problems with the analytical events associated with this report are noted below.
Analytical Sequence Sample Notes:
21121829-OOIA MTL-TCLP-7(6010D): LCS-54130 exhibits high recovery for Silver. Sample is ND
for this analyte.
21121829-OOIA TCLP-SVOC_8270E: Corresponding MS/MSD exhibited high RPD for
Hexachlorobutadiene and Hexachloroethane due to suspected sample inhomogeneity. Individual
MS/MSD percent recoveries are within acceptable criteria. Possible low bias for Pyridine due to low
recovery in LCS-54159.
Analytical Sequence QC Notes:
LCS-54130 Mtl-TCLP-7(6010): LCS-54130 exhibits high recovery for Silver. Associated samples are
ND for this analyte.
