EXECUTIVE SUMMARY
Stockton Town (Stockton) plans to drill one (1) new well built to public water well standards. The
planned location of the Old Tank Well (Well) is on the eastern margins of Stockton, Utah in Tooele
County. The Utah Drinking Water Source Protection (DWSP) Rule (R309-600, Utah Administrative
Code) requires each Public Water Supplier (PWS) to develop, submit, and implement a Preliminary
Evaluation Report (PER) for new sources of public drinking water. Stockton has contracted Bowen,
Collins & Associates (BC&A) to prepare this PER.
It is anticipated that the Well will be completed in the Holocene Younger Fan Alluvium, Pleistocene
Lacustrine Gravel, and Pennsylvanian Oquirrh Group, Butterfield Peaks Formation. The two
Holocene and Pleistocene alluvium formations are 50 to 100 feet thick and consist of
unconsolidated to semi consolidated poorly sorted boulders, gravel with sand, silt, and clay. The
Pennsylvanian Oquirrh Group is composed of cyclically interbedded limestone and clastic intervals
and is estimated to be 3,650 feet thick.
The Old Tank Well will be screened in the Oquirrh Group interbedded limestone and clastic layers
between 300 and 700 feet. The groundwater flow direction in the aquifer flows to the west-
northwest through the proposed Well site. It is anticipated that the aquifer is unconfined in the
Well area. For the purposes of this PER the Well is considered to be located in an unprotected
aquifer per the Utah DWSP Rule definition.
DWSP Zone for the Well were determined by groundwater modeling using WHPA (RESSQC).
WHPA is a program developed by the U.S. Environmental Protection Agency (EPA) for the
delineation of wellhead protection areas (Blandford, 1993). DWSP Zone 1 is simply a 100-foot
radius boundary around the well. DWSP Zones 2, 3, and 4 were delineated with WHPA using
estimated local aquifer parameters and the planned maximum pumping rate for the proposed Well.
The Old Tank Well was pumped at 600 gpm for the 250-day, 3-year and 15-year time periods
specified by the Utah DWSP Rule. This is the maximum projected pumping rate anticipated for the
new well.
A potential contamination source (PCS) inventory and assessment was conducted by BC&A and
Stockton for the proposed Well. The Utah DWSP program checklist was used as the basis for the
survey. BC&A conducted a search of the Utah DEQ Geographical Information Database (SGID). The
search did not locate any sources in the DWSP Management Area of the well. Stockton
representatives conducted field reconnaissance of the delineated DWSP zones to locate other PCSs
and provided that information to BC&A for evaluation. Each PCS was evaluated to identify
associated hazards, determine its’ location within the DWSP zone, assess whether it is adequately
controlled, and develop a priority ranking. The prioritization was based on hazard of source,
quantity of source, proximity of source to well, and relative location of source to well
(e.g., upgradient). Based on this assessment, septic tanks (PCS-4 & PCS-5) were identified as not
adequately controlled, while sparsely trafficked rural roads were found to be properly managed
and adequately controlled. However, not all adequately controlled PCS lie outside of DWSP Zone 2.
Stockton Town has adopted the Tooele County Drinking Water Source Protection Ordinance
(Tooele County, Title 9 – Chapter 5. Ground Water Protection). The delineated DWSP zones for the
Well are within the boundaries of Tooele County. The Ordinance establishes certain standards and
restrictions intended to prevent contamination of the public drinking water supply as a result of
toxic substances entering into groundwater. The Ordinance specifically defines the four Utah DWSP
Rule zones for zoning overlay and development restrictions. The Ordinance provides the ability to
adequately protect groundwater and manage both existing and future PCS’s. When constructed, the

Well and DWSP Zones will be managed and protected by the Ordinance. The existing PCSs within
the Well DWSP Zones are either permitted or conditionally permitted land uses in the Ordinance.

1.0 INTRODUCTION
Stockton Town (Stockton) plans to drill a new public supply well in Tooele County, Stockton, Utah.
The planned location of the Old Tank Well (Well) is on the eastern margins of Stockton, Utah in
Tooele County, or approximately South 924 feet and West 26 feet from the N4 Corner of Section 25,
Township 4S, Range 5W, SL B&M. Figure 1 provides a vicinity map for the proposed new Well.
As of July 26, 1993, public water systems (PWSs) in the State of Utah are required by the Drinking
Water Source Protection (DWSP) Rule (R309-600, Utah Administrative Code) to develop, submit,
and implement a PER for new sources of public drinking water. The DWSP rule requires that all
PWSs tentatively delineate DWSP Zones, develop a listing of potential contamination sources within
the DWSP Zones, and have land use agreements in place to ensure protection of the groundwater
within the Delineation Zones for new sources of public drinking water. Stockton has contracted
Bowen, Collins & Associates (BC&A) to prepare this Preliminary Evaluation Report (PER) for the
proposed well. This report is prepared in accordance with the Utah Division of Drinking Water
(UDDW) standard report format for PERs and is intended to meet the PER requirements of the
DWSP rule for the new Well.
It is anticipated the production well will be drilled and constructed during the Fall/Winter of 2024.
Once the Well has been completed and aquifer characteristics further defined, a DWSP Plan will
need to be prepared for the Well.

2.0 DELINEATION REPORT - R309-600-9(5)
A records search was conducted to obtain existing literature and data regarding the hydrogeology
for the area surrounding the proposed Well. The information sources included:
• United States Geological Survey (USGS) – Local hydrogeology
• UDDW – Well information, Rule Clarification
• Utah Division of Water Resources – Hydrogeology
• Utah Division of Water Rights – Well details and logs.
A complete listing of references used in the preparation of this report is provided in the Reference
section.
2.1 GEOLOGIC DATA – R309-600-9(5)(A)(I)
The geology and hydrogeology around the Well east of Stockton, Utah has been previously
described by Clark and others (2023) and Gardner and Kirby (2011). Appendix A provides a
general geologic map of the project area.
Generally, the Holocene to the uppermost Pleistocene basin fill deposits of Rush Valley share a
similar composition. This layer was formed by the actions of streams, debris flows, and flash floods
on alluvial fans and mountain valleys, merging with the stream alluvium unit and including a mix of
alluvium and colluvium. This section is also characterized by the presence of eolian deposits and
lacustrine fine-grained deposits below the Bonneville shoreline. The thickness of these deposits is
variable, potentially reaching 50 feet or more (Garden and Kirby, 2011).
The subsurface geology of the proposed Well location is characterized by a sequence of distinct
geologic units. The first is the Lacustrine gravel, from the upper Pleistocene, consisting of sandy
gravel to boulders composed of locally derived rock fragments deposited in shore zones of
transgressive and regressive phases of Lake Bonneville. Its variable thickness can exceed 100 feet,
potentially encompassing smaller areas of newer alluvial deposits (Clark and others, 2023).
The subsurface strata also include the Oquirrh Group, specifically the Butterfield Peaks Formation
from the Middle to Lower Pennsylvanian period (Desmoinesian-Morrowan). This formation is
notable for its cyclically interbedded limestone and clastic intervals, with the limestone ranging
from medium gray and locally fossiliferous to variations that are arenaceous, cherty, and
argillaceous across varying bed thicknesses. The thickness of the Butterfield Peaks Formation is
estimated to be 3,650 feet in the area of the proposed Well (Clark and others, 2023).
Located east of Stockton are two prominent high-angle normal faults, the Stockton and Continental
faults. Running approximately northeast to southwest, these faults exhibit a westward strike (Clark
and others, 2023).
2.2 WELL CONSTRUCTION DATA – R309-600-9(5)(A)(II)&(III)
The proposed Well will be located on the eastern margins of Stockton, Tooele County. Information
on the proposed Well and its anticipated construction is as follows:
• Wellhead Elevation: Approximately 5,234 feet above MSL
• Borehole Diameter: 24 inches

• Casing/Screen Diameter: 12 inches
• Borehole Depth: Approximately 1,100 feet
• Drilling Method: Flooded reverse circulation mud-rotary
• Screened interval: Discontinuous 600 to 1100 feet
• Pump Setting Depth: 400 feet
• Pump Type: Submersible
• Maximum Pumping Rate: 600 gallons per minute (gpm).
Figure 2 shows the location of other nearby wells. Well drilling is planned for as soon as permits
and approvals are obtained (Fall/Winter 2024). Information from the drilling, construction, and
testing of the well will be used to prepare a DWSP Plan for the new well.

2.3 AQUIFER DATA – R309-600-9(5)(A)(IV)
Appendix B contains well drillers logs for nearby wells. The Well is targeted to be completed in
Holocene Younger Fan Alluvium, Pleistocene Lacustrine Gravel, and Pennsylvanian Oquirrh Group,
Butterfield Peaks Formation. The aquifer is anticipated to be unconfined in the area; however, the
unconfined aquifer conditions assessment may be revised after the well is drilled. Based on nearby
well logs and the 2023 UGS Geologic Map of the Rush Valley 30' X 60' Quadrangle written by Clark
and others, the target aquifer at the Well site will consist predominately of alluvium and cyclically
interbedded limestone and clastic intervals.
Existing hydrogeologic data for wells located in the vicinity of the proposed Old Tank Well were
evaluated for aquifer zones and well production rates. Water rights, well logs, and pump test data
were gathered from the Utah Department of Water Rights web site. Most all the nearby wells are
irrigation wells with a few public supply wells. Appendix B contains copies of selected well logs in
the area. Data from the well driller log pump tests (Appendix B) near Stockton were analyzed to
determine the specific capacity of nearby wells. There are a few available wells in the area with
pumping information. The existing wells are within 2 miles of the sites. Transmissivity for the
proposed Old Tank Well was calculated based on pump test results from the nearest wells.
The results of this analysis are summarized in Appendix B, Table B-1.
Specific capacity is a measure of production rate per amount of drawdown. Specific capacity
estimates provide a general indication of the production efficiency of the well, however, they are
dependent on the well depth (screened intervals) and pump test duration and therefore do not
provide a direct comparison of aquifer properties between well sites.
The majority of the wells in the immediate area are less than 500 feet deep. The depth to water
varies from approximately 38 to 319 feet. The aquifer thickness for the Old Tank Well is 50-670
feet based on nearby irrigation wells. The groundwater flow direction is from the east-southeast
due to topography and as mentioned in Gardner and Kirby, 2011.

Existing wells located at similar depths and deposits yield 5-400 gpm, apart from Stockton Town’s
emergency Well with a yield of 1,120 gpm. The available data on pump tests for wells in the vicinity
is somewhat limited, leading to a constrained understanding of their specific capacities and
transmissivities. Despite this, information extracted from drillers' logs suggests an average specific
capacity of approximately 14.7 gpm/ft for the larger wells in the area. Transmissivity values were
tentatively estimated based on Gardner and Kirby's 2011 study, which cites a median value of 3,000
ft2/d for fractured bedrock. This assumption is made in the absence of more extensive, localized
testing data (refer to Table B-1, Appendix B for detailed data).

It does not appear that formal pump tests were performed on the nearby irrigation wells, though
data available on the Drillers Reports was used for the parameters for the Old Tank Well.
An aquifer test is not required for the Preliminary Evaluation Report. It is anticipated that an
aquifer pump test will be conducted when the wells are constructed, and the results will be
incorporated into final DWSP Plan for the Well.
2.4 HYDROGEOLOGIC METHODS AND CALCULATIONS – R309-600-
9(5)(A)(VII)
The preferred delineation procedure was used for delineating protection zones around the
proposed Well. The Preferred Delineation Procedure requires that four zones be delineated for
management purposes as follows:
PRELIMINARY EVALUATION REPORT
FOR THE OLD TANK WELL

BOWEN COLLINS & ASSOCIATES
STOCKTON TOWN 7
• Zone 1 is the area within a 100-foot radius from the margin of the collection area.
• Zone 2 is the area within a 250-day, groundwater time of travel to the margin of the
collection area, the boundary of the aquifer(s) which supplies water to the groundwater
source, or the groundwater divide, whichever is closer.
• Zone 3 is the area within a 3-year, groundwater time of travel to the margin of the collection
area, the boundary of the aquifer(s) which supplies water to the groundwater source, or the
groundwater divide, whichever is closer.
• Zone 4 is the area within a 15-year, groundwater time of travel to the margin of the
collection area, the boundary of the aquifer(s) which supplies water to the groundwater
source, or the groundwater divide, whichever is closer.
Groundwater modeling was used to determine these zones around the well. Zone 1 is simply a
100-foot radius boundary around the well. Zones 2, 3, and 4 were delineated using WHPA
(RESSQC) a program developed by the U.S. Environmental Protection Agency (EPA) for the
delineation of wellhead protection areas (Blandford, 1993). WHPA has been used extensively for
DWSP zone delineations. The Old Tank Well was modeled using the parameters as shown in Table
1 taken from seven adjacent irrigation/domestic wells, as well as past hydrogeologic studies (see
References) (Appendix B). Rates for the wells were assumed based on the available Well Drillers
Reports. WHPA simulated aquifer parameters under pumping conditions of the proposed well to
project wellhead protection zones. The Well was pumped at 600 gpm for the 250-day, 3-year and
15-year time periods specified by the DWSP Rule. This is the maximum projected pumping rate
anticipated by Stockton for the new well.
Table 1 lists the parameters used for the Well time-related capture zone WHPA analysis.

2.6 PROTECTED AQUIFER CLASSIFICATION – R309-600-9(3)&(6)
The aquifer surrounding the proposed Well is considered an “Unprotected Aquifer” as per the
definition in the Utah DWSP rule at this time. A Protected Aquifer means a producing aquifer in
which the following conditions are met:
1. A naturally protective layer of clay, at least 30 feet in thickness, is present above the aquifer.
2. The clay layer is laterally continuous over the extent of Zone 2.
3. The well(s) is grouted with a grout seal that extends from the ground surface down to at
least 100 feet below the surface, and through the protective layer.
At the proposed well site groundwater will likely be under unconfined or semi-confined conditions.
Although some geologic logs in the area show clay layers are present above the water table, it is not
appropriate at this time to assume that a confined aquifer, or “protected aquifer” status as defined
by the DWSP Rule will be found. Based on existing information the Well site is not located in a
Protected Aquifer. This means that the 250-day time of travel capture zone (DWSP Zone 2) around
the new Well must be protected from Potential Contaminant Sources (PCSs) by land use
agreements or groundwater protection ordinance. Criteria 3 will be incorporated into the well
design and specifications for construction of the Well.

3.0 INVENTORY OF POTENTIAL CONTAMINATION SOURCES –
R309-600-10
3.1 LIST OF POTENTIAL CONTAMINATION SOURCES – R309-600-10(1)
As required by the DWSP program, a survey was conducted to inventory PCSs within the Well
DWSP delineation zone. A search of the Utah DEQ Geographical Information Database was used to
locate CERCLA, RCRA, Toxic Release Inventory, and UST/LUST sites within and near the Well DWSP
Management Areas. In addition, a local field survey was conducted by Stockton to obtain
information and inform any identified PCS’s that they are located within the DWSP zones for the
new well. The field survey was used to identify additional potential point source and non-point
source contamination sources within the DWSP Protection Areas. The DEQ database indicated that
there are no uncontrolled PCSs in the delineated DWSP Zones for the Well. Appendix C contains
Utah DEQ database information and field PCS inventory and assessment forms. Table 3 provides the
name, address, and contact information for each PCS.

the PCS is located, an assessment if the PCS is adequately controlled, and the priority ranking for
the PCS. The list of PCSs was prioritized based on the relative risk they pose to the Well. The
prioritization was based on hazard of source, quantity of source, proximity of source to well, and
relative location of source to well (e.g., upgradient). Each of the PCS’s identified fall within DWSP
zones.

4.0 IDENTIFICATION AND ASSESSMENT OF CURRENT CONTROLS
– R309-600-10(2)
This section identifies and assesses the hazard controls that are already in place to control each PCS
identified in the previous sections for the Old Tank Well.
Stockton owns and controls the property within DWSP Zone 1 for the Old Tank Well. There are no
PCS’s located in Zone 1 for the Well.
One PCS is located in Zone 2, identified as PCS-2, Copper Street. Copper Street is a rural road
utilized for residential use and recreational access to Soldier Canyon. Due to the rural nature of the
road, transportation of hazardous material on an industrial scale is not anticipated on Copper
Street. Additionally, the delineated DWSP zones for the proposed well are within the incorporated
boundaries of Tooele County and their ordinance. The ordinance establishes certain standards and
restrictions intended to prevent contamination of the public drinking water supply as a result of
toxic substances entering into the groundwater. The ordinance specifically defines the four DWSP
zones for zoning overlay and development restrictions. Stockton believes the ordinance provides
the ability to adequately protect groundwater and manage PCSs. Copper Street is assessed as
adequately controlled due to negligible quantities and the Tooele County ordinance.
There are two PCSs located in Zone 3 that have not been previously identified. They include Mining
Road (PCS-3) and a residential septic system (PCS-4). Mining Road is a rural dirt road that is poorly
maintained and is used mainly for recreational use by passenger vehicles and personal ATVs. PCS-3
is considered adequately controlled due to the negligible quantities involved, the rural nature of the
road and the Tooele County ordinance. The residential septic system (PCS-4) is assessed as not
adequately controlled due to the potential risk of contaminant discharge to the groundwater.
Two PCSs are located in Zone 4 that have not been previously identified. They include Calumet Mine
Road (PCS-1) and a residential septic system (PCS-5). Calumet Road is a rural dirt road that is used
mainly for recreational use by passenger vehicles and ATVs. PCS-1 is considered adequately
controlled due to the negligible quantities involved, the rural nature of the road and the Tooele
County ordinance. The residential septic system (PCS-5) is assessed as not adequately controlled
due to the potential risk of contaminant discharge to the groundwater.

5.0 LAND OWNERSHIP MAP AND LIST – R309-600-13(2)(C)
A land ownership map and list are not required if ordinances are used to protect the DWSP zones.
The delineated DWSP zones for the Well are within Tooele County boundaries. Stockton Town has
adopted a Drinking Water Source Protection Ordinance (Tooele County Code (Title 9, Chapter 5)) to
protect these areas. Therefore, a land ownership map and list have not been provided. A copy of
the Tooele County Water Source Protection Areas Ordinance is included in Appendix D.

6.0 LAND USE AGREEMENTS, LETTERS OF INTENT, OR ZONING
ORDINANCES - R309-600-13(2)(D)
Groundwater protection within Tooele County is being managed under a zoning ordinance.
Appendix D contains a copy of the Tooele County Water Source Protection Areas Ordinance (Tooele
County Code (Title 9, Chapter 5)). The Ordinance establishes standards and restrictions intended
to prevent contamination of the public drinking water supply wells as a result of toxic substances
entering into groundwater. The Ordinances specifically define the four DWSP zones. The
Ordinances make provisions for review and approval of development plans and permits by the
County and allow the County to assign additional conditions or Best Management Practices (BMPs)
as necessary to protect groundwater resources. The Ordinances do not allow uncontrolled PCSs
within DWSP Zone One. The Ordinances are in place to allow for inspection and enforcement by
Tooele County. The Ordinance gives the County ability to adequately protect groundwater and
manage existing and future PCSs. When constructed the Well and DWSP Zones will be managed
and protected by the Ordinance.

CHAPTER 5. DRINKING WATER SOURCE
PROTECTION.
9-5-1.Short Title and Purpose.
9-5-2.Definitions.
9-5-3.Establishment of Drinking Water Source
Protection Zones.
9-5-4.Permitted Uses.
9-5-5.Prohibited Uses.

Requirements.
9-5-7.Administration.
9-5-1.Short Title and Purpose.
(1)This ordinance shall be known as the
"Drinking Water Source Protection Ordinance."
(2)The purpose of this ordinance is to ensure the
provision of a safe and sanitary drinking water supply
to the residents of Tooele City who receive water for
culinary and domestic use from the City by the
establishment of drinking water source protection zones
surrounding the wellheads and springs for all wells and
springs used by the City and by the designation and
regulation of property uses and conditions that may be
maintained within such zones.
(Ord. 2000-12, 08-02-2000)
9-5-2.Definitions
(1)When used in this ordinance the following
words and phrases shall have the meanings given in this
Section:
(a) "Design Standard" means a control that is
implemented by a potential contamination source to
prevent discharges to the groundwater. Spill protection
is an example of a design standard.
(b) "Drinking Water Source Protection
(DWSP) Zone" means the surface and subsurface area
surrounding a groundwater source of drinking water
supplying a public water system through which
contaminants are reasonably likely to move toward and
reach such groundwater source.
(c) "Groundwater Source" means any well,
spring, tunnel, adit, or other underground opening from
or through which groundwater flows or is pumped from
subsurface water-bearing formations.
(d) "Pollution source" means point source
discharges of contaminants to groundwater or potential
discharges of the liquid forms of "extremely hazardous
substances" which are stored in containers in excess of
"applicable threshold planning quantities" as specified
in SARA Title III. Examples of possible pollution
sources include, but are not limited to, the following:
storage facilities that store the liquid forms of extremely
hazardous substances, septic tanks, drain fields, class V
underground injection wells, landfills, open dumps,
land filling of sludge and septage, manure piles, salt
piles, pit privies, drain lines, and animal feeding
operations with more than ten animal units.
(i)The following definitions clarify the
meaning of "pollution source:"
(A) "Animal feeding operation"
means a lot or facility where the following conditions
are met: animals have been or will be stabled or
confined and fed or maintained for a total of 45 days or
more in any 12 month period, and crops, vegetation
forage growth, or post-harvest residues are not
sustained in the normal growing season over any
portion of the lot or facility. Two or more animal
feeding operations under common ownership are
considered to be a single feeding operation if they
adjoin each other, if they use a common area, or if they
use a common system for the disposal of wastes.
(B)"Animal unit" means a unit of
measurement for any animal feeding operation
calculated by adding the following numbers; the
number of slaughter and feeder cattle multiplied by 1.0,
plus the number of mature dairy cattle multiplied by
1.4, plus the number of swine weighing over 55 pounds
multiplied by 0.4, plus the number of sheep multiplied
by 0.1, plus the number of horses multiplied by 2.0.
(C)"Extremely hazardous
substances" means those substances which are
identified in the Sec. 302(EHS) column of the "TITLE
III LIST OF LISTS - Consolidated List of Chemicals
Subject to Reporting Under SARA Title III," (EPA
560/4-91-011). A copy of this document may be
obtained from: Section 313 Document Distribution
Center, P.O. Box 12505. Cincinnati, OH 45212.
(e)"Potential contamination source" means
any facility or site which employs an activity or
procedure which may potentially contaminate
groundwater. A pollution source is also a potential
contamination source.
(f)"Public water system" means a system,
either publicly or privately owned, providing water for
human consumption and other domestic uses, which:
(i)Has at least 15 service connections,
or
(ii)Serves an average of at least 25
individuals daily at least 60 days out of the year.
Such term includes collection, treatment, storage and
distribution facilities under control of the operator and
used primarily in connection with the system.
Additionally, the term includes collection, pretreatment
or storage facilities used primarily in connection with
the system but not under such control.
(g)"Sanitary Landfill" means a disposal site
where solid wastes, including putrescible wastes, or
hazardous wastes, are disposed of on land by placing
earth cover thereon.
(h)"Sanitary sewer line" means a pipeline
Tooele County - Title 9, Chapter 5
(March 13, 1998)9-4.2
that connects a residence or other building with a
sanitary sewer.
(i) "Septic tank/drain-field system" means a
system which is comprised of a septic tank and a drain
field which accepts domestic wastewater from buildings
or facilities for subsurface treatment and disposal. By
their design, septic tank/drain field system discharges
cannot be controlled with design standards.
(j) "Spring" means the ground surface outlet
of a natural underground spring including Spring
collection and control boxes, valves, piping and other
attachments.
(k)"Storm water infiltration structure" means
a structure that is intended to discharge storm water so
that it infiltrates groundwater.
(l)"Underground storage tanks" means
underground tanks used for the storage of gas, oil, or
other hazardous substances.
(m) "Wellhead" means the physical structure,
facility, or device at the land surface from or through
which groundwater flows or is pumped from
subsurface, water-bearing formations.
(Ord. 2000-12, 08-02-2000)
9-5-3.Establishment of Drinking Water Source
Protection Zones.
(1)There is hereby established the following four
use districts to be known as drinking water source
protection zones one, two, three, and four:
(a)?Zone one" is the area within a 100-foot
