Dear Bob Branch:
Waypoint Analytical Virginia, Inc. received sample(s) on 1/12/2022 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,
TaWIT Mt (slvwy/
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.

Dear Bob Branch:
Waypoint Analytical Virginia, Inc. received sample(s) on 2/2/2022 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,

Dear Bob Branch:
Waypoint Analytical Virginia, Inc. received sample(s) on 6/2/2022 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,
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.

Dear Mr. Bob Branch:
Waypoint Analytical, LLC. received sample(s) on 7/14/2022 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. Where the laboratory was not responsible for the sampling
stage (refer to the chain of custody) results apply to the sample as received.
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 2021) and NELAC unless otherwise indicated. Any parameter
for which the laboratory is not officially NELAP accredited is indicated by a '—' symbol. These are not included in
the scope because NELAP accreditation is either not available or has not been applied for. Additional
certifications may be held/are available for parameters, where NELAP accreditation is not required or applicable.
A full list of certifications is available upon request.
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,
Randy Thomas
Project Manager
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.

Dear Mr. Bob Branch:
Waypoint Analytical, LLC. received sample(s) on 8/17/2022 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. Where the laboratory was not responsible for the sampling
stage (refer to the chain of custody) results apply to the sample as received.
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 2021) and NELAC unless otherwise indicated. Any parameter
for which the laboratory is not officially NELAP accredited is indicated by a '—'symbol. These are not included in
the scope because NELAP accreditation is either not available or has not been applied for. Additional
certifications may be held/are available for parameters, where NELAP accreditation is not required or applicable.
A full list of certifications is available upon request.
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,
Jimmy R. Ferguson
Assistant Technical Director
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.

Dear Mr. Bob Branch:
Waypoint Analytical, LLC. received sample(s) on 9/21/2022 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. Where the laboratory was not responsible for the sampling
stage (refer to the chain of custody) results apply to the sample as received.
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 2021) and NELAC unless otherwise indicated. Any parameter
for which the laboratory is not officially NELAP accredited is indicated by a'—' symbol. These are not included in
the scope because NELAP accreditation is either not available or has not been applied for. Additional
certifications may be held/are available for parameters, where NELAP accreditation is not required or applicable.
A full list of certifications is available upon request.
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,
Iry
Randy Thomas
Project Manager
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.

Dear Mr. Bob Branch:
Waypoint Analytical, LLC. received sample(s) on 11/22/2022 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. Where the laboratory was not responsible for the sampling
stage (refer to the chain of custody) results apply to the sample as received.
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 2021) and NELAC unless otherwise indicated. Any parameter
for which the laboratory is not officially NELAP accredited is indicated by a '—'symbol. These are not included in
the scope because NELAP accreditation is either not available or has not been applied for. Additional
certifications may be held/are available for parameters, where NELAP accreditation is not required or applicable.
A full list of certifications is available upon request.
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,
Connie Cook
Project Manager
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.

I certify that I have examined and I am familiar with the information submitted herein. The results pertain only
to sample(s) identified and their condition at time of receipt. Based on my inquiry of the individuals
responsible for the analysis, I believe the data to be true, accurate, and complete. Sampling and field data was
obtained from submitted documents. The analysis was authorized and commissioned by the client. The
resulting data are representative of the analysis conducted on the material/samples/articles provided by the
client (or client's representative) and it's/their condition at the time of analysis. The sample(s) were analyzed
in accordance with the appropriate method , however due to the inherent limitations of the methods,
microorganisms may avoid detection. BCS Laboratories offers no express or implied warranties concerning
the quality, safety, and/or purity of any sample, batch, source, or the process they are derived from. Quality
assurance controls were performed as outlined in the method and as per Good Laboratory Practices. The
analysis and results presented in this report meet the requirements of the standards of The NELAC Institute

DATA QUALIFIER CODES
SYMBOL MEANING
B Results based on counts outside the acceptable range.
X Sample received without prior notification or delayed delivery. Analysis performed outside of
associated method required QC data set (1 QC data set per 20 samples per 168 hours).
I Value is between the laboratory method detection limit & the practical quantitation limit.
J1 The sample matrix interfered with the ability to make any accurate determination.
J2 No Quality Control criteria exist for the component.
J3 The data are questionable because of improper laboratory or field protocols.
L Off scale high. Actual value is known to be greaterthan value given.
N Presumptive evidence forthe presence of material. There is an indication thatthe analyte is
present, but the confirmation requirement was not met.
O Sampled, but analysis not performed.
Q Sample held beyond the accepted holding time.
U Indicates that the compound was analyzed for but not detected. The specified component was
not detected. The reported value is the method detection limit.
V Analyte was detected in both sample and the method blank. Data may not be accurate.
Y Laboratory analysis was from an improperly preserved sample; the data may not be accurate
Z Too many colonies present (TNTC); the numeric value given represents the upper end of the
value that can be determined based on the volume.
7 Data are rejected and should not be used. QC data for analyte did not meet acceptance criteria.
Presence or absence of analyte could not be confirmed.

SYMBOL MEANING
B Results based on counts outside the acceptable range.
X Sample received without prior notification or delayed delivery. Analysis performed outside of
associated method required QC data set (1 QC data set per 20 samples per 168 hours).
I Value is between the laboratory method detection limit &the practical quantitation limit.
J1 The sample matrix interfered with the ability to make any accurate determination.
J2 No Quality Control criteria exist for the component.
J3 The data are questionable because of improper laboratory or field protocols.
L Off scale high. Actual value is known to be greater than value given.
N Presumptive evidence for the presence of material. There is an indication that the analyte is
present, but the confirmation requirement was not met.
O Sampled, but analysis not performed.
Q Sample held beyond the accepted holding time.
U Indicates that the compound was analyzed for but not detected. The specified component was
not detected. The reported value is the method detection limit.
V Analyte was detected in both sample and the method blank. Data may not be accurate.
Y Laboratory analysis was from an improperly preserved sample; the data may not be accurate
Z Too many colonies present (TNTC); the numeric value given represents the upper end of the
value that can be determined based on the volume.
7 Data are rejected and should not be used. QC data for analyte did not meet acceptance criteria.

I certify that I have examined and I am familiar with the information submitted herein. The results pertain only
to sample(s) identified and their condition at time of receipt. Based on my inquiry of the individuals
responsible for the analysis, I believe the data to be true, accurate, and complete. Sampling and field data was
obtained from submitted documents. The analysis was authorized and commissioned by the client. The
resulting data are representative of the analysis conducted on the material/samples/articles provided by the
client (or client's representative) and it's/their condition at the time of analysis. The sample(s) were analyzed
in accordance with the appropriate method , however due to the inherent limitations of the methods,
microorganisms may avoid detection. BCS Laboratories offers no express or implied warranties concerning
the quality, safety, and/or purity of any sample, batch, source, or the process they are derived from. Quality
assurance controls were performed as outlined in the method and as per Good Laboratory Practices. The

DATA QUALIFIER CODES
SYMBOL MEANING
B Results based on counts outside the acceptable range.
X Sample received without prior notification or delayed delivery. Analysis performed outside of
associated method required QC data set (1 QC data set per 20 samples per 168 hours).
I Value is between the laboratory method detection limit &the practical quantitation limit.
J1 The sample matrix interfered with the ability to make any accurate determination.
J2 No Quality Control criteria exist forthe component.
J3 The data are questionable because of improper laboratory orfield protocols.
L Off scale high. Actual value is known to be greater than value given.
N Presumptive evidence forthe presence of material. There is an indication that the analyte is
present, but the confirmation requirement was not met.
0 Sampled, but analysis not performed.
Q Sample held beyond the accepted holding time.
U Indicates that the compound was analyzed for but not detected. The specified component was
not detected. The reported value is the method detection limit.
V Analyte was detected in both sample and the method blank. Data may not be accurate.
Y Laboratory analysis was from an improperly preserved sample; the data may not be accurate
Z Too many colonies present (TNTC); the numeric value given represents the upper end of the
value that can be determined based on the volume.
7 Data are rejected and should not be used. QC data for analyte did not meet acceptance criteria.
Presence or absence of analyte could not be confirmed.
** Not reported due to interference.

I certify that I have examined and I am familiar with the information submitted herein. The results pertain only
to sample(s) identified and their condition at time of receipt. Based on my inquiry of the individuals
responsible for the analysis, I believe the data to be true, accurate, and complete. Sampling and field data was
obtained from submitted documents. The analysis was authorized and commissioned by the client. The
resulting data are representative of the analysis conducted on the material/samples/articles provided by the
client (or client's representative) and it's/their condition at the time of analysis. The sample(s) were analyzed
in accordance with the appropriate method , however due to the inherent limitations of the methods,
microorganisms may avoid detection. BCS Laboratories offers no express or implied warranties concerning
the quality, safety, and/or purity of any sample, batch, source, or the process they are derived from. Quality
assurance controls were performed as outlined in the method and as per Good Laboratory Practices. The

SYMBOL MEANING
B Results based on counts outside the acceptable range.
X Sample received without prior notification or delayed delivery. Analysis performed outside of
associated method required QC data set (1 QC data set per 20 samples per 168 hours).
I Value is between the laboratory method detection limit & the practical quantitation limit.
J1 The sample matrix interfered with the ability to make any accurate determination.
J2 No Quality Control criteria exist forthe component.
J3 The data are questionable because of improper laboratory orfield protocols.
L Off scale high. Actual value is known to be greaterthan value given.
N Presumptive evidence forthe presence of material. There is an indication that the analyte is
present, butthe confirmation requirement was not met.
O Sampled, but analysis not performed.
Q Sample held beyond the accepted holding time.
U Indicates that the compound was analyzed for but not detected. The specified component was
not detected. The reported value is the method detection limit.
V Analyte was detected in both sample and the method blank. Data may not be accurate.
Y Laboratory analysis was from an improperly preserved sample; the data may not be accurate
Z Too many colonies present (TNTC); the numeric value given represents the upper end of the
value that can be determined based on the volume.
7 Data are rejected and should not be used. QC data for analyte did not meet acceptance criteria.
Presence or absence of analyte could not be confirmed.

I certify that I have examined and I am familiar with the information submitted herein. The results pertain only
to sample(s) identified and their condition at time of receipt. Based on my inquiry of the individuals
responsible for the analysis, I believe the data to be true, accurate, and complete. Sampling and field data was
obtained from submitted documents. The analysis was authorized and commissioned by the client. The
resulting data are representative of the analysis conducted on the material/samples/articles provided by the
client (or client's representative) and it's/their condition at the time of analysis. The sample(s) were analyzed
in accordance with the appropriate method , however due to the inherent limitations of the methods,
microorganisms may avoid detection. BCS Laboratories offers no express or implied warranties concerning
the quality, safety, and/or purity of any sample, batch, source, or the process they are derived from. Quality
assurance controls were performed as outlined in the method and as per Good Laboratory Practices. The
analysis and results presented in this report meet the requirements of the standards of The NELAC Institute
(TNI), ISO 17025, and the FL DOH Environmental Laboratory Certification Program, as applicable unless

DATA QUALIFIER CODES
SYMBOL MEANING
B Results based on counts outside the acceptable range.
X Sample received without prior notification or delayed delivery. Analysis performed outside of
associated method required QC data set (1 QC data set per 20 samples per 168 hours).
I Value is between the laboratory method detection limit & the practical quantitation limit.
J1 The sample matrix interfered with the ability to make any accurate determination.
J2 No Quality Control criteria exist for the component.
J3 The data are questionable because of improper laboratory or field protocols.
L Off scale high. Actual value is known to be greaterthan value given.
N Presumptive evidence forthe presence of material. There is an indication that the analyte is
present, but the confirmation requirement was not met.
0 Sampled, but analysis not performed.
Q Sample held beyond the accepted holding time.
U Indicates that the compound was analyzed for but not detected. The specified component was
not detected. The reported value is the method detection limit.
V Analyte was detected in both sample and the method blank. Data may not be accurate.
Y Laboratory analysis was from an improperly preserved sample; the data may not be accurate
Z Too many colonies present (TNTC); the numeric value given represents the upper end of the
value that can be determined based on the volume.
7 Data are rejected and should not be used. QC data for analyte did not meet acceptance criteria.
