Date of Report: ______May 18, 2023______
Brendon Reali of Atlantic Design Engineers arrived at the 810 Wakeby Road property (Site) at
approximately 2:15PM to locate four (4) existing groundwater morning wells and obtain existing
groundwater measurements. Monitoring wells MW-1 through MW-4 were located within the
northern portion of the property (Figure 1) and groundwater was measured using a GeoTech
Portable Water Level Meter. The monitoring wells were approximately 2-inches in diameter and
composed of PVC (Figures 2-5). The wells were protected with a steel casing, with the exception
of MW-1, and extended approximately 2-feet above grade. The elevation of existing grade at the
base of each monitoring well was surveyed using a GPS unit.
The Cape Cod Commission’s (CCC) has provided a method to use current water level
measurements at the project site in conjunction with monthly index well data to estimate the
maximum seasonal high groundwater level. A review of the Cape Cod Commission’s (CCC) High
Groundwater Level Data Viewer was conducted to estimate seasonal high groundwater levels at
the Site. Based on provided information, the Index Observation Well for the Site is SDW-253R,
which was measured on April 9, 2023, at 48.22-feet below ground surface (b.g.s). The associated
Water-Level Range Zone for the Site is Zone B and the water level adjustment for is 4.50-feet.
Subtracting this adjustment from the Site’s depth to water yields the depth to estimated high

groundwater. High Ground-water Level Computation forms have been completed for each
monitoring well and provided as Appendix A.
Additionally, an existing irrigation well was located on the southern portion of the Site
approximately 300-feet north of the entrance along Wakeby Road. An associated Flexcon Flex-
Lite Pressure Tank is housed within a wooden shed (Figure 6).
Standing groundwater depth below the ground surface (b.g.s) was measured with the following
