CTL|Thompson, Inc. is performing a groundwater monitoring study at the above
referenced project. This letter presents the most recent groundwater measurements from
piezometers at the site.
On June 19th through 26th, 2023, twelve borings were drilled at the locations shown on
Figure 1 (TH-1 through TH-12) using solid-stem augers and a truck-mounted drill rig. The
monitoring holes were fitted with temporary PVC piezometers to facilitate monthly groundwater
measurements. Groundwater was measured relative to the existing ground surface by a
representative from our firm. The table below summarizes our groundwater measurements to
date.
