Mr. Ryals, WithersRavenel, Inc. (WR) has prepared this Letter Report documenting the completion of monitoring and recovery well abandonment activities at the B&G Grocery site located at 2896 East
Maiden Road, Maiden, Catawba County, North Carolina. Activities outlined herein were completed
under NCDEQ Contract # N70522-C, Task Authorization (TA) 02 for the site, issued by NCDEQ on October 3, 2023. WR mobilized to the site on October 11-12, 2023 to complete the abandonment of monitoring and recovery wells MW-1, MW-4R, MW-6, MW-9R, MW-11, MW-12, MW-13, MW-15, VRQ-3, OBS-
1, RW-1, RW-2, RW-3, RW-4, RW-5, RW-6, RW-7, RW-8, RW-9, RW-10, RW-13, RW-14, RW-15, RW-16, RW-17, and RW-18. The activities completed in association with this TA are discussed in the following paragraphs. Monitoring & Recovery Well Abandonments Monitoring wells MW-1, MW-4R, MW-6, MW-9R, MW-11, MW-12, MW-13, MW-15, VRQ-3, OBS-1 were gauged on October 11-12, 2023 using a decontaminated electronic oil/water interface meter. No light non-aqueous phase liquid (LNAPL) was measured within the wells.
Each monitoring well was abandoned through the emplacement of 3/8-in dia. bentonite chips to within 1-ft of each wells’ top of casing (TOC). The remainder of each well was filled with neat cement grout extending out of the TOC filling the monitoring well manways.

2023 using a decontaminated electronic oil/water interface meter. No light non-aqueous phase
liquid (LNAPL) was measured within the wells. Each recovery well was abandoned through the emplacement of 3/8-in dia. bentonite chips to within 1-ft of each wells’ TOC. The remainder of each well was filled with neat cement grout, filling
the casing. The approximately 2x2x2-ft well vaults were then filled with sand to the surface.
A table is provided below documenting the total depth of each monitoring and recovery well at the time of abandonment.
