Thermal Preservation: *Sample Temperature measured immediately after removal from cooler.
*Notify management immediately of any sample that did not meet temperature requirements or frozen.
*If multiple parameters, in additional to BacT are collected for a site, a receipt temperature for the BacT plus
another bottle must be measured and recorded on the COC.
Requirements: DW: 5 6'C WW: 5 6'C BacT: 5 10"C LT2 Crypto/Giardia: 5 20'C LT2 E. coli: 5 10'C
Do sample receipt temperatures meet requirements (including requirement by downward trend)? EfYes 1:1No, explain below.
Downward trend required to meet requirement? Yes
* At time of receipt into the laboratory, the allowed downward trend may be applied to meet temperature requirement. Initial temperature
from the sample collector becomes critical. If samples are received next day, receipt temperatures must meet requirements listed above.
Chemical Preservation: Note: *If samples are not preserved correctly, notify Personnel. Do not check acT, TOC, VOA, THM and HAA.
All containers needing preservation are found to be in EPA compliance? ✓(Yes �No �N/A
If no, explain.
*If the aH of a metals(excluding HgJ is incorrect these steps are followed: *If the pH of any other chemically preserved sample is incorrect
1. On COC, document sample pH prior to adding additional preservative. (not including metals), follow these steps:

Dear Cara Rusmisell:

Main 704.529.6364
www.waypointanalytical.com
Waypoint Analytical, LLC (Charlotte) received sample(s) on 8/23/2023 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.
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 were performed in accordance with guidelines established by the USEPA (including 40 CFR 136
Method Update Rule May 2021) 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,
Terri W Cole
Laboratory 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.

QUALIFIERS
Project: QUARTERLY
Pace Project No.: 92675666
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
Pace Analytical Services, LLC
9800 Kincey Ave. Suite 100
Huntersville, NC 28078
[phone]
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
