Attn: Mr. Scott Ryals    Reference:  Letter Report ‐ Verification of Water Line Connections & Supply Well Sampling  Former Lois Shinn Site  5475 NC Highway 152 West  China Grove, Rowan County, North Carolina  Groundwater Incident Number: 40772  WR Project Number:  02141214.31    Dear Mr. Ryals:     WithersRavenel, Inc. (WR) has prepared this Letter Report documenting the verification of water  line connections and sampling 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 on October 17, 2019 and performed under  task authorization (TA) 06 for the site, in association with NCDEQ Contract # N17005.           Verification of Water Line Connections  WithersRavenel mobilized to the subject site on December 6, 2019 for the purposes of verifying  the connection of the newly installed McNeely and Roberts supply wells to the residences serviced  by these wells, followed by the collection of samples from each well for laboratory testing.      The first of the two wells was installed between September 24 and 25, 2019 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.  WR verified connection of this well to the residence through the  physical observation of the supply line to the wellhead.  Connection of the residence to the supply  well was accomplished through the installation of ½‐inch diameter (dia.) cross‐linked polyethylene  (PEX) tubing running from the wellhead to a central connection point located beneath the  residence.  The PEX tubing is run through a 1‐inch dia. trace pipe, buried approximately 18‐inches  beneath surface grade.  Photographs of the supply line connections are included as an attachment.          WithersRavenel Our People. Your Success.  Letter Report – Verification of Water Line Connections & Supply Well Sampling     Former Lois Shinn Site  January 2020  Page 2 of 4    The second of the wells installed 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 has been  operating.  WR verified connection of this well to the residence through the physical observation  of the supply line to the wellhead.  Connection of the residence to the supply well was  accomplished through the installation of ½‐inch dia. PEX tubing running from the wellhead to the  line formerly connecting the residence to the effluent side of the POE system on the property  (within the well house associated with the now out‐of‐use supply well on the property).  The PEX  tubing is run through a 1‐inch dia. trace pipe, buried approximately 18‐inches beneath surface  grade.  Photographs of the supply line connections are included as an attachment.        WR also sampled each of these wells on December 6, 2019, however, the samples were mis‐placed  or lost by the laboratory after they had been relinquished to the lab’s courier service and not  analyzed.  As a result, WR returned to the locations on December 31, 2019, and re‐sampled the  wells as described below.      Water Supply Well Sampling  WR personnel returned to the site on December 31, 2019 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”) did not indicate the presence of targeted compounds at concentrations  above the laboratory method detection limit for SM6200B.     WithersRavenel Our People. Your Success.  Letter Report – Verification of Water Line Connections & Supply Well Sampling     Former Lois Shinn Site  January 2020  Page 3 of 4  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  Methyl‐Ethyl‐ Ketone (MEK) 27 4,000 4,000,000 Not  Established  Chloroform 5.9 70 70,000 Not  Established  Toluene 22 600 258,000 1,000    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 MEK, chloroform and  toluene in the sample are thought to be a remnant of the PVC solvent utilized in the emplacement  of the well casing and emplacement of the delivery line connection.  It is expected these  compounds 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 on a quarterly basis over the next  year.    WithersRavenel appreciates the opportunity to be of service to the Federal & State Lead Program.
