HARVEY WELL CONSTRUCTION HISTORY
The Harvey Well was drilled in 1961 to a total depth of 510 feet. The well was cable tool drilled,
and a 16-inch mild steel casing was installed and perforated from a depth of 330 feet to 510 feet
(See attached Driller’s Report from 1961).

In 1999, the well was fitted with a sanitary seal by drilling three 6-inch holes on the outside of the
well casing to a depth of 100 feet and pressure grouted to surface. The well was also lined with
14-inch mild-steel wire-wrap screens from 360 feet to 500 feet and mild-steel blank casing
extended to the surface (See attached Driller’s Report from 1999).

The Harvey well has experienced a significant decline in production over several years of use and
it was determined that the well would need significant renovations to restore the original
production. The City of Cedar Hills and Hansen, Allen & Luce Engineers determined that it was
best to renovate the well and deepen it to approximately 800 feet. On October 13, 2022, Water
Well Services began drilling and driving 10-inch mild steel casing to a total depth of 810 feet. The
10-inch casing was perforated (see attached Well Design Memo) and cutoff at 495 feet below
ground level. The 14-inch screen and casing that was originally installed in 1999 was removed
from the well and 12-inch stainless-steel wire-wrap screens were installed from 380 feet to 480.
Stainless steel blank was installed from 480 feet to 500 and tightly fitted around the 10” blank
casing. Stainless steel blank was installed on top of the screens from 340 feet to 380 feet with
mild steel blank casing extended to the surface (see attached Driller’s Report and Figure for the
as-built construction details). A 6-9 gradation artificial filter pack was installed between the existing
16-inch and the newly installed 12-inch liner. The well was redeveloped using a dual-swab tool
and test pumped with a line-shaft turbine pump. A constant rate test was performed at 1,500 gpm
with a sustained drawdown of approximately 6 feet (see attached Memo detailing the test
pumping).

CONFORMANCE
This Memo certifies that in all aspects, the Harvey Well was drilled and constructed in accordance
with the Utah Division of Water Rights (R655-4) and Utah Division of Drinking Water (R309-515)
Rules.

CONSTANT RATE TEST
A constant rate pump test was performed on the Harvey Well on August 23, 2024, at a flow rate
of 1,500 gpm. The test began at 11:15 AM and ran until 9:15 PM which resulted in 6.3 feet of
drawdown. Drawdown increased steadily for about the first 40 to 50 minutes of the test until it
stabilized at a drawdown of 6.3 feet. There was no increase in drawdown for the remainder of
the 10-hour test. Transmissivity was computed using AQTESOLV software developed by
HydroSOLV and evaluated using the Cooper-Jacob solution for confined aquifers. Long-term
pumping water levels were predicted based on the best fit curve using this solution (See Attached
AQTSOLV Solution). Results of the AQTESOLV analysis are shown in Table 1. Figures 1 & 2
detail the stabilizing trend of the pumping water relative to the static water level and drawdown.
Also depicted is the stabilizing trend of the specific capacity of the well.

WATER QUALITY
Water samples were collected on August 23, 2023, and all parameters are within drinking water
standards for a public water supply well. The full results of the water quality reports from
Chemtech Ford are attached to this Memo.

CONCLUSIONS
The chosen rate for the constant-rate test (1,500 gpm) was due to the limitations on the diameter
of the well which prevented a larger pump from being installed. It is likely that the actual safe
yield of the aquifer supplying this well is much larger than the tested rate of 1,500 gpm. The test
was terminated after 10 hours of pumping because there was no observable change in the
pumping level of the well for a duration of 9 hours. This test meets the requirements of a constant-
rate test as defined by R309-515-6(10)A(iv).

The tested rate is easily below the safe yield of the aquifer based on the limited drawdown
observed (only 6.3 feet) and the calculated high specific capacity (238 gpm/ft). The Harvey Well
is very stable and efficient at 1,500 gpm and the predicted long-term pumping level at 1,500 gpm
is between 8 and 9 feet of total drawdown.
