Dear Mr. Ryals: 

WithersRavenel, Inc. (WR) has prepared this Letter Report documenting the sampling of two water 
supply wells recently installed in proximity to the Former Lois Shinn site situated at 5475 NC 
Highway 152 West in China Grove, Rowan County, North Carolina.  Activities described herein 
were authorized via email on February 17, 2020 and performed under task authorization (TA) 08 
for the site, in association with NCDEQ Contract # N17005.        

Verification of Water Line Connections 
WithersRavenel mobilized to the subject site on February 20, 2020 for the purposes of purging 
and sampling the newly installed McNeely and Roberts supply wells for laboratory testing.   

The first of the two wells id situated on the property of Carl & Beth Anne Roberts, located at 5390 
W NC 152 in China Grove, NC.  This well, designated by WR as “Roberts 3” or “WSW‐5C” was 
installed as a replacement for a supply well located on the property with documented petroleum 
contamination at concentrations exceeding NC 2L and/or US EPA MCLs.    

The second of the wells is situated on the property of Bryan & Ashlyn McNeely at 5145 W NC 
152 in China Grove, NC.  This well, designated by WR as “McNeely 2” or “WSW‐2A” was installed 
as a replacement for the supply well located on the property with petroleum contaminants 
exceeding NC 2L Standards for which a point‐of‐entry (POE) system had been operating.

Water Supply Well Sampling 
WR personnel mobilized to the site on February 2, 2020 for the purposes of obtaining supply well 
samples from the McNeely and Roberts supply wells.  Prior to the collection of the samples, each 
well was purged a minimum of ten‐minutes by opening the sample port located at each wellhead 
forcing the well pump(s) to run continuously.  After such time as purging of each well had been 
completed, WR personnel obtained samples from the wells for testing by Standard Method (SM) 
6200B.  Samples were collected in laboratory grade glassware containing chemical preservative.  
Following collection, samples were placed in a cooler containing ice and relinquished to Waypoint 
Analytical Services, Inc. (Waypoint), formerly Prism Laboratories, Inc for shipment to their 
laboratory in Charlotte, NC and eventual analysis. 

Laboratory Results 

WSW‐2A (McNeely 2) 

Laboratory results for the sample obtained from the newly installed well on the McNeely property 
(WSW‐2A or “McNeely 2”) indicated the presence of chloromethane at a concentration above the 
laboratory method detection limit for SM6200B, and above the 2L Standard for the compound: 

Compound 
Name 
Level Detected 
(µg/L) NC 2L Standard (µg/L) GCL (µg/L) US EPA MCL 
Chloromethane 4.6 3.0 3,000 Not 
Established 

The presence of chloromethane in the sample is thought to be a remnant of the PVC solvent 
utilized in the emplacement of the well casing and installation of the delivery line connection.  It is 
expected the compound will be eliminated over time through evaporation of the solvents and 
future pumping of the well.   

WSW‐5C (Roberts 3) 

Laboratory results for the sample obtained from the newly installed well on the Roberts property 
(WSW‐5C or “Roberts 3”) indicated the presence of the following targeted compounds: 

Compound 
Name Level Detected (µg/L) NC 2L Standard (µg/L) GCL (µg/L) US EPA MCL 
Acetone 28 6,000 6,000,000 Not 
Established 
Chloroform 2.4 70 70,000 Not 
Established 

The presence of acetone in the sample is considered by WR to be a laboratory artifact or cross 
contaminant associated with laboratory cleaning agents.  The presence of chloroform in the 
sample is thought to be a remnant of the PVC solvent utilized in the emplacement of the well 
casing and installation of the delivery line connection.  It is expected that chloroform will be 
eliminated over time through evaporation of the solvents and future pumping of the well.

In the case of all compounds reported in the sample, none was reported at a concentration above 
NC 2L Standards or US EPA Maximum Contaminant Levels (MCLs).  

Laboratory reports for each of the samples obtained from WSW‐2A and WSW‐5C are included as 
an attachment.   

WR recommends the collection of samples from each well in May 2020. 

WithersRavenel appreciates the opportunity to be of service to the Federal & State Lead Program.
