Dear Ms. Ghiold:
Terracon Consultants, Inc. (Terracon) is pleased to submit this Letter Report for monitoring well
abandonment activities conducted at the former North Hickory Furniture site, located at 1079
3rd Avenue Drive NW, Hickory in Catawba County, North Carolina (Figure 1). This letter report
has been prepared in general accordance with North Carolina Department of Environmental
Quality (NCDEQ), Underground Storage Tank (UST) Section Assessment Guidelines, dated
January 19, 2021, and Task Authorization No. 06, approved on April 10, 2023.
Terracon personnel mobilized to the site on May 2, 2023, to locate monitoring wells MW-1R and
MW-2R, measure total well depths, oversee well abandonment activities and the removal of well
pads for former monitoring wells MW-1, MW-1R, and MW-6D, and document site conditions
prior to and following site activities. Monitoring well construction information and groundwater
elevation data is provided in Table 1. Locations of the monitoring wells and relative site
features are illustrated on Figure 1. Field notes and photographs from site activities are
included in Appendix A.
Environmental Drilling and Probing Services (EDPS), a North Carolina Certified drilling
contractor, completed the monitoring well abandonment activities. The monitoring wells were
abandoned with neat cement grout, tremie-piped into the well casing from the bottom of the
