Ms. Price: 

WithersRavenel, Inc. (WR) has completed this Letter Report to document the limited groundwater 
sampling event described in our proposal number TA-02 for the above referenced facility, approved
by the Federal & State Lead Program on July 26, 2023 under Contract # N70522-C. WithersRavenel 
mobilized to the subject site on September 8, 2023 for the purposes of gauging, purging and 
sampling monitoring wells MW‐3, MW‐4, MW‐8 and MW‐10 (Figure 1).   

Groundwater Sampling 

Prior to the purging and sampling of the monitoring wells as described below, each well was 
gauged using a decontaminated electronic water level indicator.  In performance of well gauging, 
no free product/LNAPL was detected in any of the wells measured.  Results of well gauging are 
summarized below:

Following gauging, monitoring wells MW‐3, MW‐4, MW‐8 and MW‐10 were purged with 
dedicated, disposable polyethylene (PE) bailers.  Following purging and adequate recharge of 
groundwater within the wells, samples were decanted directly into pre‐preserved laboratory 
grade sample containers provided by Waypoint Analytical, LLC (Waypoint) for analysis of VOCs 
by Standard Method (SM) 6200B. 

Laboratory Results 

Analytical results for groundwater samples obtained from site monitoring wells September 
showed the following:  

 Several targeted compounds were reported in the samples from MW‐3, MW‐4, MW‐8 and 
MW‐10 at concentrations exceeding their NC 2L Standards.   
 Benzene was reported in the samples collected from MW‐3 and MW‐4 at concentrations 
exceeding the GCL for the compound.   

Analytical results from the September 2023 groundwater sampling event are included in Table 
B‐4 (Abbreviated).  Field notes and site photos are included as Attachment A, while the 
laboratory analytical report is provided as Attachment B. 

WR completed a receptor survey update at the site in association with the current TA.  Results 
of the receptor survey update are outlined under a separate cover.  Results of the update 
revealed that no active water supply wells are located within a 1,500‐ft radius of the site, while 
all occupied properties within that radius are connected to the Craven County municipal water 
system.   

WR appreciates the opportunity to be of service to the Federal & State Lead Program.  Should 
you have any questions regarding the attached, please do not hesitate to contact 
WithersRavenel at (919) 469‐3340. 

Cordially,

Dear Matt James:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 9/12/2023 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
