Please provide comments/notes on your current submittal below.
Please note that in 2016 to the existing permit for NEFCO-Quincy, MA plant were added two more NEFCO plants - in
Cumberland, MD and West Palm Beach, FL. The MD and FL plants did not ship product to NC in 2019. In fact, they
never shipped, neither in 2018, nor in 2017 and 2016. Mr. Troy Doby instructed me: in this situation, when sending
the Annual Reports, the MD and FL Plant Managers to sign the DMSDF Form, showing 0 tons shipped. These
signed forms are attached too, they are part of the report. Our old permit expired Dec 31, 2019. This 2019 annual
report is under it. We have a new permit, effective Jan 1, 2020, which has the same permit #, i.e. is an extension of
the old one.
Please attach all information required or requested for this submittal to be review here.

To Whom It May Concern:
Enclosed are three copies of the 2019 Annual Land Application Report Forms and Laboratory Analysis
Reports as required by Permit Number WQ0013276 issued to New England Fertilizer Company (NEFCO).
This permit provides for the distribution of heat -dried biosolids produced by NEFCO at the processing
facility located in Quincy, Norfolk County, Massachusetts.
In October 2016 two more NEFCO plants were added — in West Palm Beach, FL and Cumberland, MD.
None of these plants shipped to NC during 2019. Therefore a DMSDF Form, showing 0 tons shipped, is
included for each of them.
The attachments include analytical data of NEFCO's pellet biosolids during year 2019 for:
- Baseline metals, nutrients and nitrogen. The monthly composite samples were analyzed by
Eurofins Spectrum Analytical, in Agawam, MA
- Fecal coliform. The monthly grab samples were analyzed by ESS Labs, in Cranston, RI
- TCLP. The annual composite sample was analyzed by Eurofins Spectrum Analytical, in Agawam,
MA
During 2019 NEFCO-Quincy, MA shipped 87.48 dry tons of Class A EQ biosolids to the state of North
Carolina. All the product was used for agricultural land -application, and was managed by 1 user - Caines
Brothers. The shipments were in May 2019, 3 trucks.
Sincerely,
Michael V. Ryan

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J-Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 0.6 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.
See below for any non -conformances and issues relating to quality control samples and/or sample analysis/matrix.

Notes and Definitions
This parameter is outside laboratory lcs/lcsd specified recovery limits.
m This parameter is outside laboratory ms/msd specified recovery limits.
This parameter is outside laboratory rpd limits.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
PH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra- laboratory split sample which is used to document the precision of a method in a given sample matrix
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J-Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 1.9 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.

Notes and Definitions
B Present in blank, no bias suspected
el TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
PH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra- laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

Notes and Definitions
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
PH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra- laboratory split sample which is used to document the precision of a method in a given sample matrix
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

This parameter is outside laboratory rpd specified recovery limits.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
PH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra- laboratory split sample which is used to document the precision of a method in a given sample matrix
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J-Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 1.0 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.
Analyses for Total Hardness, pH, and Total Residual Chlorine fall under the state of Pennsylvania code Chapter 252.6 accreditation by
rule.
See below for any non -conformances and issues relating to quality control samples and/or sample analysis/matrix.

Notes and Definitions
el TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
QM7 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable
LCS recovery.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
PH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra- laboratory split sample which is used to document the precision of a method in a given sample matrix
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J-Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 2.2 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.
Analyses for Total Hardness, pH, and Total Residual Chlorine fall under the state of Pennsylvania code Chapter 252.6 accreditation by
rule.

Notes and Definitions
* Outside of specification
el TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
D Data reported from a dilution
DI Indicates for dual column analyses that the result is reported from column 1
GS1 Sample dilution required for high concentration of target analytes to be within the instrument calibration range.
QM9 The spike recovery for this QC sample is outside the established control limits. The sample results for the QC batch were
accepted based on LCS/LCSD or SRM recoveries within the control limits.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
PH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra- laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J-Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 4.7 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.

Notes and Definitions
Outside of specification
el TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
DI Indicates for dual column analyses that the result is reported from column 1
This parameter is outside laboratory lcs/lcsd specified recovery limits.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
PH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra- laboratory split sample which is used to document the precision of a method in a given sample matrix
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J-Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 0.6 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.

Notes and Definitions
Outside of specification
el TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
D2 Indicates for dual column analyses that the result is reported from column 2
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
PH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra- laboratory split sample which is used to document the precision of a method in a given sample matrix
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J-Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 1.0 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.

Notes and Definitions
Outside of specification
el TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
DI Indicates for dual column analyses that the result is reported from column 1
This parameter is outside laboratory lcs/lcsd specified recovery limits.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
PH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra- laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method
blank is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction.
Sample RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

Notes and Definitions
* Outside of specification
c 1 TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
D 1 Indicates for dual column analyses that the result is reported from column 1
D2 Indicates for dual column analyses that the result is reported from column 2
1 This parameter is outside laboratory lcs/lcsd specified recovery limits.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
pH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method
blank is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction.
Sample RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
Q-Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 2.2 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.
Soil Analysis for EPA 300.0 Nitrate/Nitrite Testing
The method for nitrate/nitrite via EPA 300.0 does not stipulate a specific holding time for product/soil/solids. For aqueous samples,
40 CFR 136 specifies a holding time of 48 hours from sampling to analysis. Soils are held at 4 degrees Celsius prior to extraction
with deionized water with all soil samples analyzed within 48 hours of this procedure.
See below for any non -conformances and issues relating to quality control samples and/or sample analysis/matrix.

Notes and Definitions
* Outside of specification
c 1 TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
D 1 Indicates for dual column analyses that the result is reported from column 1
D2 Dual column analysis the result is reported from column 2
1 This parameter is outside laboratory lcs/lcsd specified recovery limits.
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
pH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method
blank is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction.
Sample RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
Q-Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 4.4 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.
Soil Analysis for EPA 300.0 Nitrate/Nitrite Testing
The method for nitrate/nitrite via EPA 300.0 does not stipulate a specific holding time for product/soil/solids. For aqueous samples,
40 CFR 136 specifies a holding time of 48 hours from sampling to analysis. Soils are held at 4 degrees Celsius prior to extraction
with deionized water with all soil samples analyzed within 48 hours of this procedure.
The regulatory hold time for pH is immediately. This pH was performed in the laboratory and may be considered outside of holdtime.
Corrosivity is based solely on the pH analysis performed above.

Notes and Definitions
c 1 TKN is reported as Organic Nitrogen in the Blank, LCS, DUP and MS.
c2
c3
DI Indicates for dual column analyses that the result is reported from column 1
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
pH The method for pH does not stipulate a specific holding time other than to state that the samples should be analyzed as
soon as possible. For aqueous samples the 40 CFR 136 specifies a holding time of 15 minutes from sampling to analysis.
Therefore all aqueous pH samples not analyzed in the field are considered out of hold time at the time of sample receipt.
All soil samples are analyzed as soon as possible after sample receipt.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method
blank is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction.
Sample RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

- Please use Solid Materials Matrix for the testing. I checked the "Soil" matrix for the sample
because there is no option "Biosolids" (what our product is), "Solid" or "Other".
- Please, test Total Solids via SM 2540-G in a NJ DEP and PA DEP certified Lab for this method. Using
Eurofins Lancaster, PA Lab works; Phoenix Lab, CT does not.
- Please test Total Phosphorus in a N1 DEP and PA DEP certified Lab for solid matrix. Using Eurofins
Lancaster, PA Lab works; Phoenix Lab, CT does not.
- Please, report the data on a dry weight basis
- Please, make sure the detection limit for Selenium is 0.5 mg/Kg or less

Analytical Summary
The project as described above has been analyzed in accordance with the ESS Quality Assurance Plan.
This plan utilizes the following methodologies: US EPA SW-846, US EPA Methods for Chemical
Analysis of Water and Wastes per 40 CFR Part 136, APHA Standard Methods for the Examination of
Water and Wastewater, American Society for Testing and Materials (ASTM), and other recognized
methodologies. The analyses with these noted observations are in conformance to the Quality Assurance
Plan. In chromatographic analysis, manual integration is frequently used instead of automated
integration because it produces more accurate results.
The test results present in this report are in compliance with TNI and relative state standards, and/or
client Quality Assurance Project Plans (QAPP). The laboratory has reviewed the following: Sample
Preservations, Hold Times, Initial Calibrations, Continuing Calibrations, Method Blanks, Blank Spikes,
Blank Spike Duplicates, Duplicates, Matrix Spikes, Matrix Spike Duplicates, Surrogates and Internal
Standards. Any results which were found to be outside of the recommended ranges stated in our SOPS
will be noted in the Project Narrative.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
Q-Flag).
All non -detects and all results below the reporting limit are reported as "<" (less than) the reporting limit in this report.
The samples were received 1.5 degrees Celsius, please refer to the Chain of Custody for details specific to temperature upon receipt.
An infrared thermometer with a tolerance of +/- 1.0 degrees Celsius was used immediately upon receipt of the samples.
If a Matrix Spike (MS), Matrix Spike Duplicate (MSD) or Duplicate (DUP) was not requested on the Chain of Custody, method
criteria may have been fulfilled with a source sample not of this Sample Delivery Group. If method or program required
MS/MSD/Dup were not performed, sufficient sample was not provided to the laboratory.
All VOC soils samples submitted and analyzed in methanol will have a minimum dilution factor of 50. This is the minimum amount
of solvent allowed on the instrumentation without causing interference. Soils are run on a manual load instrument. 100ug of sample
(MEOH) is spiked into 5ml DI water along with the surrogate and added directly onto the instrument. Additional dilution factors may
be required to keep analyte concentration within instrument calibration range.
Reactivity (40 CFR 261.23) Case Narrative:
These samples do not exhibit the characteristics of reactivity as defined in 40 CFR 261.23, sections (1), (2) and (4); however,
Eurofms Spectrum Analytical, Inc. does not test for detonation, explosive reaction or potential, or forbidden explosives as defined in
40 CFR 261.23, sections (3), (6), (7) and (8).
Reactive sulfide and cyanide are tested at a pH of 2 and not tested at all conditions between pH 2 andl2.5 as stated in 40 CFR 261.23,
section (5); thus reactive cyanide and sulfide results as reported in this document can not be used to support the nonreactive properties
of these samples.
The responsibility falls on the generator to use knowledge of the waste to determine if the waste meets or does not meet the
descriptive, prose defmition of reactivity.
TOC via Lloyd Kahn Case Narrative:
Following the acidification via a 1:1 phosphoric acid solution to remove the inorganic carbon, the sample is dried in a 100°C oven for
10-15 minutes. A homogenous sample is then weighed into the platinum boat and tested, on a dry weight basis, for TOC using the
Lloyd Kahn method.
Analysis Specific Comments:
SW-846 826013, GC/MS Volatiles
Sample #s: 1191186
Reporting limits were raised due to sample foaming.
SW-846 8270D, GC/MS Semivolatiles
Sample #s: 1191184
Reporting limits were raised due to interference from the sample matrix.
40 CFR 261.21(a)(2), Wet Chemistry
Sample #s: 1191184
The sample did not spontaneously ignite when exposed to air or water.
The sample did not ignite by friction.
The sample vapors did not ignite when exposed to a flame using a
closed cup apparatus.
SW-846 Chapter 7.3, Wet Chemistry
Sample #s: 1191184
Reactivity:
This sample was extracted and analyzed by the interim method described in
SW-846 Revision 3, December 1996 - Chapter 7.3. The Interim Guidance for
Reactive Cyanide and Reactive Sulfide (SW-846 Sections 7.3.3 and 7.3.4 of
Chapter 7 - December 1996) identifies a reactive material as generating
more than 250 mg/kg of hydrogen cyanide or 500 mg/kg of hydrogen sulfide.
This waste is not considered hazardous due to reactivity based on that
standard. These results do not reflect total cyanide or total sulfide. On
July 14, 2005, EPA published a rule in the Federal Register that removed
the Interim Guidance and the method referenced above. At this time there
is no specific guidance or a method to be used to evaluate "Reactivity".
There is no relevant protocol -specific QC and/or performance standards non -conformances to report.

Notes and Definitions
NEG Negative
dry Sample results reported on a dry weight basis
NR Not Reported
RPD Relative Percent Difference
[2C] Indicates concentration was reported from the secondary, confirmation column.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method
blank is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction.
Sample RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

[2C] Indicates concentration was reported from the secondary, confirmation column.
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method
blank is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non -zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction.
Sample RDLs are highly matrix -dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.
