CTL|Thompson, Inc. is performed 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. Table 1 summarizes our
groundwater measurements to date.
We appreciate the opportunity to work with you on this project. If you have any
additional questions or concerns, please contact the undersigned.
Sincerely,
CTL|THOMPSON, INC.
