Mr. Ryals: 

WithersRavenel, Inc. (WR) has completed this Letter Report to document the groundwater 
sampling event described in our proposal number TA‐02 for the above referenced site approved 
by the Federal & State Lead Program on May 26, 2023 under Contract #N70522‐C.  
WithersRavenel mobilized to the subject site on June 23, 2023 for the purposes of gauging, 
purging and sampling monitoring wells MW‐2R, MW‐3, MW‐9R and MW‐10. WR could not 
locate monitoring well MW‐10 in dense vegetation and overgrowth. 

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.  Results of well gauging are 
summarized below:

Following gauging, well MW‐3 was purged with a dedicated, disposable polyethylene (PE) bailer.  
Following purging and adequate recharge of groundwater within the well, 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 monitoring well MW‐3 in June 2023 
showed the following:  

 Several targeted compounds were reported in the sample from MW‐3 at concentrations 
exceeding their NC 2L Standards.   
 Results for samples from MW‐3 showed total VOC decreases of 26% over data for the well 
from March 2023. 

Analytical results from the June 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. 
The nearest water supply well previously reported in proximity to the release is WSW‐1, 
(reportedly) located 192 feet cross‐gradient from the site.  WR previously sent the owner of 
WSW‐1 a letter confirming the water supply well is inactive, but a response has not been 
received to date. Based on information from the Town of Pollocksville, the property on which 
WSW‐1 is located is connected to the municipal water supply.   
One municipal water supply, WSW‐2, is located 659 feet cross‐gradient from the site.  An 
additional municipal water supply well, WSW‐3, is located 1,517 feet cross‐gradient from the 
site. 
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, 
WithersRavenel

Dear Kevin Buchanan:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 6/23/2023 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,
Angela D Overcash Senior Project Manager
