Report Number: 21-245-0013
Project Description: South Durham
Dear Mary Brewer:
Waypoint Analytical Virginia, Inc. received sample(s) on 9/2/2021 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,
TCUtire &tinie ,
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.

Case Narrative
Synagro
Lot Number: WL29023
This Report of Analysis contains the analytical result(s)for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report. Where
sampling is conducted by the client, results relate to the accuracy of the information provided, and as the
samples are received.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace")
Laboratory Quality Manual, standard operating procedures (SOPs), and Pace policies. Any exceptions to
the TNI standards, the Laboratory Quality Manual, SOPs or policies are qualified on the results page or
discussed below.
Pace is a TNI accredited laboratory; however, the following analyses are currently not listed on our TNI
scope of accreditation: Drinking Water: VOC (excluding BTEX, MTBE, Naphthalene, & 1,2-
dichloroethane) EPA 524.2, E. coli and Total coliforms SM 9223 B-2004, Solid Chemical Material: TOC
Walkley-Black, Biological Tissue: All, Non-Potable Water: SGT-HEM EPA 1664B, Silica EPA 200.7,
Boron, Calcium, Silicon, Strontium EPA 200.8, Bicarbonate, Carbonate, and Hydroxide Alkalinity SM 2320

Coliform Colilert-18.
Where applicable, all soil sample results (including LOQ and DL if requested) are corrected for dry weight
unless flagged with a "W" qualifier.
If you have any questions regarding this report, please contact the Pace Project Manager listed on the
cover page.
The pH analysis associated with the sample(s) in this report was/were performed after the method
recommended 15 minute holding time.
Metals by ICP
Due to the matrix and low percent solids, the following samples had an initial weight that is 3x greater
than the standard procedure: WL29023-001. The LOQ has been adjusted accordingly.
Inorganic Non-Metals
The following sample was diluted due to the nature of the sample matrix for Nitrate and Nitrite: WL29023-
001. The LOQ has been elevated to reflect the dilution.
All samples analyzed with batch 28656 were analyzed using expired ascorbic acid reagent. This run was
a re-analysis of a previous run that was analyzed using a linear calibration range that was slightly greater
than 6 months old, per SOP criteria. The instrument was re-calibrated and the samples were re-
analyzed, using the new calibration, and similar results were obtained. Thus, re-ananlysis is not required
for samples that were within calibration range. All instrumentation check standards and method criteria
were met.

Report Number: 21-036-0008
Project Description: Durham Brown WTP
Dear Mary Brewer:
Waypoint Analytical Virginia, Inc. received sample(s) on 2/5/2021 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,
TCUtire &tinie ,
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.

Metals by ICP
Due to the low % solids, the initial sample amount used for the following sample deviated 3X greater than
the standard procedure: W127094-001. A dilution was performed due to matrix interferences. The LOQ
has been adjusted accordingly.
Inorganic Non-Metals
The following sample was diluted due to the nature of the sample matrix for Nitrate/Nitrite: WI27094-001.
The LOQ has been elevated to reflect the dilution.

Lime Ac exchangeable acidity
If testing finds that soil pH is too low for the crop(s) indicated, a lime recommendation will be given in units of either B boron
ton/acre or lb/1000 sq ft. For best results, mix the lime into the top 6 to 8 inches of soil several months before planting. BS% % CEC occupied by basic cations
For no-till or established plantings where this is not possible, apply no more than 1 to 1.5 ton/acre (50 lb/1000 sq ft) at one Ca% % CEC occupied by calcium

is applied. If MG is recommended and lime is needed, use dolomitric lime. Cu-I copper index

Recommendations for field crops or other large areas are listed separately for each nutrient to be added (in units of K-I potassium index

Agronomist's Comments:
ATTENTION: This report was flagged with a"C"and/or"Z"to alert you that copper and/or zinc have accumulated in the soil and are approaching a level that could be
detrimental to crop production. The C and Z symbols are printed on your report for soil test Zn and Cu index levels of 2000 or more for agronomic crops;for peanuts with
zinc, the level is 250.This note is designed to be a"trigger"that allows enough time to either reduce the rate of application or find another field for application of biosolids
and/or waste water.The CTL(critical toxic level)for Cu and Zn is set at a 3000 index;for peanuts with zinc,the level is 500. Maintaining a pH of 6.0 or higher may reduce
potential for toxicity, especially for Zn. These levels are used by DENR as a benchmark to determine when application of waste products should be stopped.The CTL for
copper and zinc was set to revent levels from accumulating to the point where they become toxic to crops grown on a field.

Lime Ac exchangeable acidity
If testing finds that soil pH is too low for the crop(s) indicated, a lime recommendation will be given in units of either B boron
ton/acre or lb/1000 sq ft. For best results, mix the lime into the top 6 to 8 inches of soil several months before planting. BS% % CEC occupied by basic cations
For no-till or established plantings where this is not possible, apply no more than 1 to 1.5 ton/acre (50 lb/1000 sq ft) at one Ca% % CEC occupied by calcium
time, even if the report recommends more. You can apply the rest in similar increments every six months until the full rate CEC cation exchange capacity
is applied. If MG is recommended and lime is needed, use dolomitric lime. Cu-I copper index
