Re: Health Risk Evaluation of Water Supply
Tracking ID: RAST Incident Number 3303

Dear Mr. Rudolf:

Please find attached the Sample Analytical Results for a water sample collected from your well, identified as 7918
Holman, located at 7918 Holman Mill Road, Snow Camp, Alamance County, on May 11, 2023. The sample was
collected and analyzed as part of the investigation of a petroleum release in the vicinity. The water sample was
analyzed for specific target analytes (contaminants), which are listed on the attached Sample Analytical Results.
Contaminants were detected in the water sample, as shown on the attached Sample Analytical Results.

Because contaminants were detected in the water sample, a Health Risk Evaluation of the water supply was performed
by an environmental toxicologist in the Division of Waste Management. The Health Risk Evaluation, which is
attached also, compares the detected concentration of contaminants to acceptable concentrations and provides a
recommendation for safe use of the water.

If you have any questions, please contact Dave Lilley at [phone] or contact me at the address or telephone
number listed below for the Winston-Salem Regional Office, or via email at [e-mail].

Sincerely,

Aaron R. Williamson, L.G.
Hydrogeologist

RE: Health Risk Evaluation Incident # 3303 Rudolf Leitner Well Sampling Results 7918 Holman Mill Road Snow Camp, NC
During this sampling event, two contaminants were detected in the well water. The standards used to determine if the water is suitable for drinking and cooking are the United States Environmental Protection Agency’s Maximum Contaminant Levels (MCLs) or, if no MCLs exist, North Carolina Groundwater Standards (2L).
If any contaminant concentrations exceed applicable standards for using the water for drinking and cooking, those contaminant concentrations are further analyzed to determine if the water is suitable for other household uses, such as showering, bathing, washing dishes, flushing toilets, and hand washing. The chart below compares the detected contaminant concentrations with the applicable
standards:
Sample ID Contaminant Concentration (µg/L) MCL (µg/L) 2L (µg/L)
µg/L – Stands for micrograms of contaminant per liter of water and is roughly equivalent to parts per billion.
* This value is based on odor, the health-based value is 2,000 µg/L.
RECOMMENDATION: None of the contaminants detected exceeded the applicable water values. Therefore, no restrictions on the use of this water are recommended at this time.

Case Narrative
NCDEQ-UST
Lot Number:YE12074
This Report of Analysis contains the analytical result(s)for the sample(s)listed on the Sample Summary following this
Case Narrative.The sample receiving date is documented in the header information associated with each sample.
All results listed in this report relate only to the samples that are contained within this report.Where sampling is
conducted by the client,results relate to the accuracy of the information provided,and as the samples are received.
Sample receipt,sample analysis,and data review have been performed in accordance with the most current
approved The NELAC Institute (TNI)standards,the Pace Analytical Services,LLC ("Pace")Laboratory Quality
Manual,standard operating procedures (SOPs),and Pace policies.Any exceptions to the TNI standards,the
Laboratory Quality Manual,SOPs or policies are qualified on the results page or discussed below.
Pace is a TNI accredited laboratory;however,the following analyses are currently not listed on our TNI scope of

Insufficient sample volume was provided to perform matrix spike/matrix spike duplicate (MS/MSD)for analytical batch
75663.An LCS/LCSD was run in lieu of an MS/MSD.

SVOA 625.1
The Fluorophenol surrogate recovery for sample YE12074-001 was outside the lower control limit.This sample was
used for the MS/MSD.This surrogate in the MS failed the same as the parent sample and the MSD was on the low
end of the control limit range.The surrogate failure is attributed to matric and a re-extraction was not performed.
YE12074-001 (7918 Holman)(Run 1)(Analysis Batch 75875)(Prep Batch 75540)
Also,MS/MSD for batch 755470 and parent sample YE12074-001 (7918 Holman),recovered outside the upper
control limit for Phenol.The associated LCS passed acceptance criteria.
The method blank associated with batch 75540 had Di-n-butyl phthalate detected at a concentration that was above
the DL but below the LOQ. All samples associated with this method blank that have detections for Di-n-butyl
phthalate have been flagged with a "B”.
EPH
The method blank associated with batch 75524 had C9-C18 Aliphatics detected at a concentration that was above
the LOQ.The associated sample,YE12074-001 (7918 Holman)was non-detect;therefore,the results have been
reported.
If you have any questions regarding this report,please contact the Pace Project Manager listed on the
cover page.
