Ms. Blalock: 

WithersRavenel, Inc. (WR) has prepared this Letter Report documenting the collection of samples 
from select supply wells at the facility.  Activities outlined herein were completed under NCDEQ 
Contract # N122019B, Task Authorization (TA) 06 for the site, issued by NCDEQ on January 23, 
2023.   

WR mobilized to the site on January 26, 2023, to complete the, purging and sampling of supply 
wells WSW‐Bracken and WSW‐Janney (Hernandez).    

Supply Well Sampling  
Samples were obtained from supply wells WSW‐Bracken and WSW‐Janney (Hernandez) on 
January 26, 2023 following purging.  By way of purging, the well pump(s) within each supply well 
were energized and allowed to operate continuously for a period of no less than 10‐minutes time, 
after which samples were decanted directly into pre‐preserved, laboratory‐grade sample 
containers provided by Waypoint.  The samples obtained from the monitoring wells were 
submitted for laboratory analysis of VOCs by SM6200B.

Laboratory Results 
Laboratory results for analysis of samples collected from supply wells on January 26, 2023 did not 
show the presence of targeted compounds by SM6200B in supply well WSW‐Bracken at 
concentrations above the laboratory method detection limit.  Data for WSW‐Janney (Hernandez) 
showed the following compounds present: 

WSW‐Janney (Hernandez) – January 26, 2023 
Compound Name Level Detected NC 2L Standard NC GCL ES‐EPA MCL 
IPE 5.05 µg/L 70 µg/L 70,000 µg/L N/A 
MTBE 8.10 µg/L 20 µg/L 20,000 µg/L N/A 

Levels of the compounds detected in the Janney (Hernandez) well were not reported at 
concentrations exceeding their NC 2L Standards.  Levels of each compound detected are 
generally consistent with those for past sampling of the well.   

The laboratory analytical report for the January 2023 event is included as Attachment A.  

WithersRavenel appreciates the opportunity to be of service to the Federal & State Lead Program.  
If you have questions or comments regarding this letter report, please contact Matthew James at

Dear Matt James:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 1/27/2023 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,
Angela D Overcash Senior Project Manager
