(Golder) is submitting this letter report summarizing over -drilling and decommissioning of groundwater monitoring wells MW-16S and MW-16D at the Moore County Landfill in Aberdeen, North Carolina (NC). This report details monitoring well abandonments conducted by Golder in May 2019. The planned decommissioning activities were approved by the NC Department of Environmental Quality (DEQ) in a February 22, 2019. ABANDONMENT OF PIEZOMETERS On May 17, 2019, Golder geologists provided oversight for the decommissioning of two groundwater monitoring wells in accordance with Title 15A of the North Carolina Administrative Code (NCAC) 2C .0113(b). The piezometers were decommissioned by South Atlantic Environmental Drilling and Construction Company, Inc. (SAEDACCO) of Fort Mill, South Carolina, a North Carolina certified well drilling company. Monitoring wells MW-16S and MW-16D are located in the footprint of the next proposed horizontal of the construction and demolition landfill (i.e., Phase 6). Therefore, monitoring wells MW-16S and MW-16D, were over -drilled to remove well materials and surface completions, and then grouted to approximately 2 feet below the anticipated base grades. The well locations are shown on Drawing 1. Copies of the well abandonment records (Form GW-30 Rev. 5/06) for the decommissioned monitoring wells are included as Attachment A. Details of the abandonment procedures are provided below. Decommissioning by Over -Drilling As presented, groundwater monitoring wells MW-16S and MW-16D were over -drilled with 6 5/8-inch inner diameter (ID) hollow stem augers (HSAs), which are a sufficient size to remove well construction materials from the borehole before being back -filled with neat cement grout from the bottom of the borehole to approximately 17 feet below ground surface (bgs) via tremie pipe procedures. Grouting was ceased at approximately 17 feet bgs to prevent damage to the abandonment during the construction of Cell VI as these monitoring wells are located in a future cut area. The remaining annulus was backfilled with cuttings. Surface completions of each monitoring well Golder Associates NC, Inc. 5B Oak Branch Drive Greensboro, North Carolina, USA 27407 T: +1 336 852-4903 +1 336 852-4904 Golder and the G logo are trademarks of Golder Associates Corporation golder.com Jaclynne Drummond, Hydrogeologist Project No. 0739615018 Solid Waste Section, Division of Waste Management June 17, 2019 including protective casings, pads, and bollards were removed.
