Dear Mr. Ryals:

CES Group Engineers, LLP (CES), while under contract with the North Carolina Department of
Environmental Quality (NCDEQ), Contract No.: N042023, executed on February 24, 2023, is
submitting this Well Abandonment Letter Report to you for the above referenced property, via
email transmission.

The subject site is located at 2127 Wilkinson Boulevard, in an urban and commercial area of
Charlotte, Mecklenburg County, North Carolina, as depicted on Figure 1.

On July 3, 2023, four groundwater monitoring wells, MW-1, MW-1A, MW-4 and MW-5, with well
depths totaling 193-feet, as depicted on Figure 2, were abandoned by Daniel Summers of
Carolina Soil Investigations, LLC, Olin, NC, a North Carolina Certified Well Contractor (License
Number 2579-A). Photographs of the abandoned monitoring wells are attached in Appendix A.

The monitoring wells were generally abandoned by pouring tremie grout into the well casing to a
depth of approximately 6-inches below grade, then completing the abandonment with neat
cement to grade, including filling in the well vault, securing the well by placing the well cover back
on the well vault, and then bolting the well cover tight, as applicable.

Copies of the well abandonment records are included in Appendix B.

The performed work was authorized by NCDEQ Task Authorization (TA) #02, approved on June
8, 2023. Should you have any questions in regards to this submittal, please do not hesitate to
contact me at [phone].

Regards,

Greg Hans, PMP
