Mr. May,
This letter is being submitted to serve as the reporting period for the month of August 2021 for the
Nags Head Acres groundwater dewatering well system. Per the conditions of Permit No. WV0700153,
monthly groundwater samples are required to be collected from the well system during operation of
the wells on a monthly basis. Groundwater samples will be analyzed for Fecal Coliform, chlorides, and
nutrients (Total Nitrogen, Ammonia, Nitrate, Total Phosphorus). The volume of water pumped from
the well system shall be monitored and tracked with flows reported on a monthly basis.

Enclosed for your records, are the results from the August 2021 reporting period for Permit No.
WV0700153 for the Nags Head Acres Dewatering Well project. Enclosed is a spreadsheet of the
groundwater sample data for Ammonia Nitrogen, Chlorides, Total Nitrogen, Total Phosphorus, and
Fecal Coliform in addition to the total recorded flows for the monthly period.

Should you have any questions or comments regarding the submitted information, please do not
hesitate to contact me at [phone] or David Ryan, PE at [phone]. Thank you for your
assistance in this matter.
