Re: Retention Pond Water Sample Results for Brownfields Permit
Glen Wilde, LLC Property,
State Farm Road,
Boone, NC 28607
Watauga County

Dear Mr. Duque:

On January 14, 2021, Seramur & Associates personnel visited the Glen Wilde, LLC site to collect a
surface water sample from the retention pond.

Water was present in the retention pond off the northwest corner of the apartment buildings. One
surface water sample was collected from the pond. The sample was collected in laboratory clean jars,
sealed with Teflon lined lids, labeled and placed on ice. A chain of custody was initiated. Samples were
shipped to Waypoint Laboratories in Charlotte, NC and analyzed for volatile organic compounds using
EPA Method 6200B.
Volatile organic compounds were not detected above the NCDEQ 2L Groundwater Standards by
Standard Method 6200B in the water sample. The laboratory reports and chain of custody are attached.

We appreciate the opportunity to assist you with this monitoring event. If you have any questions,
please contact me at [phone].

Sincerely,
Keith C. Seramur, P.G.
Consulting Geologist

Keith C. Seramur, P.G., PC 2
