Draft Hydrogeologic Assessment
Stirling Property
267 Sierra Trail, Quilcene, WA 98376
Dear Mr. Stifling,
This report presents our analysis ofhydrogeologic conditions at the' Stirling property
located at 267 Sierra Trail, Quilcene, Jefferson County, Washington. The general
location of the property is shown on Figure 1. This assessment addresses the relevant
components of an Aquifer Recharge Area Report per Jefferson County Uniform
Development Code (UDC) Section 3.6A 0 as required by the -UDC Groundwater
Protection/Seawater Intrusion Amendments, March 3, 2003. Mr. Charles Stirling
authorized our services on July 2, 2003.
It is my understanding that a water sample from your well, submitted as a required '-. ' . "'
element of an application for a residential building permit (received May 6, 2003),
exceeded a concentration of 200ppm for chl0ride. According to UDC ordinance 03-303-
03 and subsequent revisions, a single well water measurement above 200-ppm chloride
triggers a high-risk salt-water intrusion zone (SIPZ). A SIPZ is defined in the UDC as
"aquifers and laq...d overlying aquifers with some degree of vulnerability to seawater."
SIPZ are "defined either by proximity to marine shoreline or by proximity to
.
groundwater sources that have demonstrated high chloride reading."
-SCOPE
The UDC mandates, among .other things, that for a well to be approved by the JefferSon
County Community Development Center as source of potable water, the owner must
provide evidence through a hydrogeol0gical assessment that a reasonable probability
exist that use Of the proposed well will not degrade the subject aquifer. This report
proposes to show, using currently acceptable methods of analysis, .tt~.~t pumping of water
from the Stirling well will not degrade the water quality ofneighborihg wells and
therefore not degrade the aquifer.
Draft Stirling Property Assessment 1 of 9 7/22/2003
In preparing this hydrogeologic assessment, we reviewed the following reports and
d~ument:
1) Water Well Reports on file with the Washington State Department of Ecology.
2) On-site yield test data.
3) On-site well water quality data..
4) Jefferson County Unified Building Code. .
5) Property Maps Jefferson County.

SITE DESCRIPTION
The Stifling property is located on the southwestern end of the Toandos Penim. ula in
Jefferson County (Fig~e 1). The Toandos Peninsula is bounded by the Dabob Bay on
the west and Hood canal on the east. The property is a located in Lot 3, SW ¼ Section
32, Township 26N, Range l W. The Jefferson County parcel number is 601324003
(Figure 2)
Chxrrently the developments on the property consist ora trailer pad, trailer septic, and
water well.(ABPS06) and a small building used as a shop and for storage. Mr. Stifling
proposes to build a house on the property, which requires a building permit. The .
proposed building site is located on the eastern portion of the 1 O-acre rectangular-shaped
parcel.
The current SIPZs within the vicinity of Stifling property are shown on Figure 3, 'A

Russell well which has a history of chloride concentrations greater than 200 mg/L. The
Stifling well is currently located outside, the SIPZs.
HYDROGEOLOGICAL ASSESSMENT
.,Well Log Information
Water Well Reports on file with the Washington State Department of Ecology (Ecology,
2003) were obtained and reviewed for the area within the vicinity of the Stifling Property.
There are three Wells located on properties adjacent to the Stit~g property. The
locations of the wells are shown in Figure 4. The well logs and a table of well
construction values are '.included in Attachment A. .
Well ABPS06, the Stifling well, was drilled in 1995 and is located ~out 70 feet west of
the eastern boundary of the Stifling property (Figure 4). The well is"loeated
Stifling Property Assessment 2 of 9 7/22/2003
approximately 1,500 feet from the shoreline of Dabob Bay. The well has been used to
supply a trailer septic system and a shop at the property. This well has been in service
since 3/3/95. The only available record of its water quality prior to this study is that
submitted with the building application. Review of the United States Geological Survey
(USGS) Seabeck topographic map (Seabeek 7 ~A" Quad) indicates .that the well is located
a[ an approximate elevation of 360 feet above sea level. The well log indicates that it is
438 feet deep with a surface seal to 18 feet depth. The well penetrates about 426 feet of
material described as "claybound gravel", "hardpan", and sand and gravel. Water bearing
silty gravel is recorded from 426 to 438 feet depth. Bedrock was not encountered by the
boring. The depth to water in the well at the time of well completion (March 1995) was
recoi'ded at 360 feet below the top of the casing.
The Holt well is located on the adjacent property (601324008) north of the Stifling
property. The well is located approximately 1,200 feet from the shoreline of Dabob Bay.
Based on the USGS topographic map (Seabeck 7 ½" Quad). The top of well casing is
estimate to be at an elevation of 370 feet. The Holt well was drilled to a depth of 430 feet
below ground surface (bgs) in November 1992. The well is completed in a unit described
in the log as a "lt. bm. clay w/gravel & wood-chips and water." Currently the well is
capped and not in use. The depth to water at the time of completion (November 1992)
was recorded as 358 feet below the top of the casing.
The Barron well is located on the Soini property (601333012) located east of the Stirling
property. The Barron well.is located approximately 2,500 feet from the shoreline of
Dabob Bay. The top 0fwell casing is estimate to be at an elevation of 190 feet. The well'
was completed in November 1983 to a depth of 214 feet bgs. The well is open to a
water-bearing unit described as a '~brown packed W/B (i.e. water bearing) sand and
gravel. The depth to water in the well at the time of completion (November 1983) was
recorded at 148 feet below the top of the casing.
Two wells were completed on the Russell property. The Russell wells are located" ..... -'-
approximatel~.l,100 feet northwest of the Stifling well..The ground surface elevation at
the wells is estimated to be 390 feet. The wells are approximately750 feet fi'om the
shoreline of Dabob Bay.
The first Russel.1 well (ABC310) was completed in August 1994 to a depth of 448 feet
bgs. The well is open to a water-bearing zone described as coarse gravel. The depth to
water at the time of completion (September 1998) was recorded as 387 feet below the top
of the casing.
The second Russell well (AEA529) was completed in' September 1998 to a depth of-417
feet bgs. The well is open to a water-bearing zone described as brown' sand and grave[
The depth to water at the time of completion (September 1998) was recorded as 350 feet
below the top of the casing. The Russell well is defined as a high n~sk 8IPZ because it
has a history of chloride analyses above 200 mg/L. ~ '
·
Draft Stifling Property Assessment 3 of 9 7/22/2003
Based on Soil strata, well completion depth, elevations above sea level and distance to the
shoreline, it is appears that the Holt, Russell and Stifling wells may draw water from the
.same aquifer. The Russell wells are significantly closer to the.shoreline than the Holt and
Stifling wells. Based on its stratigraphie position and water level elevation, the Barton
well may draw water from a different aquifer than the Holt, Russell and Stifling wells.
Ground Water,Elevation
Ground water flows from areas of high head to areas of low head. Based on the topology
of the property and the proximity to shoreline, groundwater is assumed to be flowing in a
westerly direction and discharging into the Dabob Bay. The depth to water in the Stifling
well at the time the well completion (March 1995) was recorded at 360 feet below the top
of the casing. Assuming an elevation at the top of the well of 360 feet, the ground water
elevation is 0 feet, relative to mean sea level. The depth to the water measured in June
2003 was 358 'feet indicating that the water level has not changed significantly since
1995.
Well Wa. ter,Flow Test Data
_
Gresham Well Drilling of Poulsbo, Washington, performed a well water flow test on the
Stifling well on March 8, 1995. The well is equipped with a 2 horsepower Goulds brand
submersible pump (serial number 10GS20). The well was pumped at a flow rote of 14
· gallons per minute (gpm) for a period of 60 minutes. At the end of the test a drawdown
of 31 feet was recorded. Water levels in the well fully recovered with 3 minutes after
pumping was terminated.
A second well water flow test was conducted by Mr. Charles Stifling on Juno 15, 2003.
The well was pumped at flow rates of 3, 6 and 12 gallons per minute. Ground water level
drawdown measurements, flow measurements and conductivity measurements' were "
recorded during the test. Attachment B contains the flow test data eolleeted-xt-~g test.--
........ A maximumdrawdown of 5.08 feet was recorded during the 12-gpm test, Water--levels~:
in the well fully recovered within a few minutes aftei pumping was terminated.
Downgradient Capture, Zone
Based on data obtained from well testing, a distance to the seaward or downgradient
stagnation point was calculated. The downgradient stagnation point is the area in the
ground water flow field where water is not moving towards the well. This parameter is a
quantitative' indicator of the extent of seawater intrusion caused by well pumping. This
distance (D, ft) is determined by tho following relationship (EPA, 1994, p. 77):

gradient is estimated to be 0.02.
Substituting the average T for Kb and simplying the original formulation of the equation
for DSP the following relationship is obtained: '~

The results show that at a pumping rate of 12 gpm the Stifling well will draw ground
Water from the downgradient or seaward side of a distance of only 37 feet, leaving a
buffer zone of more than a 1000 feet. between the sea and the downgradient influence of
the well. .
..Water,Quali _tv Data
-The primary water quality concern that is related to water use is the possible increase in
dissolved comfiments because of saltwater intrusion. Chloride concentration is the
primary indicator of seawater intrusion. Typical concentrations of chloride in seawater
range from 18,000 to 19,000 rog/L, whereas in freshwater chloride concentrations are less
than 100 mg/L. The EPA see6ndary drinking water standard for chloride is 250 mg/L is
based upon taste, corrosion and staining, effects, not risk to health.
When groundwater is pumped fi'om aquifers that are in hycira~ic connection with the sea,
the gradients that are set up.may induce a flow of salt water from the sea toward the well. -
Under natural conditions, the flow of freshwater towards the sea.will limit the. landward .-.-.
movem_ent of .s,gl......~._..a.t...er~_.With the development.of ground-water supplies, and subsequent .............................
lowering of the water table, the dynamic balance between'fresh and seawater is disturbed,
permi~g seawater to intrude into parts of the aquifer,
The Stifling well was first sampled for chloride on'April 30, 2003. The water samples
were collected from a water faucet in the shop building. A chloride concentration of 249
mg/!~' was detected in the sample. Three chloride samples from a tap at the wellhead
were collected on June 3, 2003 during the water well flow test: The. water samples were
collected at the end of the each 0fthe pumping steps. The concentration of chloride
detected in the samples collected during the flow test tests was 160, 128 and 175 mg/L.
The lab results are provided in Attachment C. A summary of chloride concentrations is
provided in the .following table. ·

Conductivity is a measure of the ability of.water to conduct electricity and is measured in
units ofuhmos/cm. Conductivity was measured with field monitoring equipment and
provides a good field tool for evaluating the relative level of dissolved constituents in
ground water. Recorded conductivity values range from 820 to i287 uhmos/cm.
Conductivity values showed a decreasing trend dropped during each test (Attachment C).
The conductivity'reading collected throughout pumping do not show an increasing trend
as would be expected if saltwater intrusion were occurring.
Water quality data was available from Jefferson County for the Barron well. The
chloride concentration detected in the Barron was reported as 154 mg/L.
RECOMMENDATIONS
We recommend the following actions for the Stifling Property to address the actions for
development as required bY the UDC.
'--I,- ~ water meter should be installed on the Stifling well to monitor water iisage:
. ._
Meter readin-g-~-should be submitted to the JeffemonCounty at least twice a year. ' ' --
2. Samples of water should be collected from the well and analyzed by a certified
laboratory for conductivity and chloride twice a year (recommended sampling in
April and August). The water samples should be collected from a tap at the
wellhead. The sample should be placed in a pre-cleaned plastic bottles preferably -.
obtained fi'om the laboratory. Before sampling water should be purged fr6m the
pump and well casing for a minimum of 10 minutes. The purging will remove ·
water that has been in contact with the pump and associated piping and allow
sampling of water from the aquifer. The laboratory results should be submitted to
Jefferson County.
3. Water conservation measures are recommended. Recommended measures
include.installing low-flow fixtures, limiting krigation, and Ilae use of dishwasher
and clothes washer only with full'loads.

Intercepted Precipitation (roof drains, drive runoff, etc) should be detained, and
infiltrated on-site to the extent possible.
CONCLUSIONS
The following conclusions are developed based on the hydrogeologic data reviewed in
preparing this report:
1. The Stifling well is completed in water-bearing sand-and gravel unit that
contributes water to several other wells in the area. The Russell well, which
appears to be cbmpleted in the same water-bearing zone has a history of detected
·
concentrations greater than 200 mg/L. The Russell well is located significantly
closer to the sea than the Stifling well, which probably accounts for the difference
in chloride concentrations.
2. Chloride concentrations collected from the Stifling well range from 120 to 249
m.g~. Only one sample from the Stirling well contained concentrations of
chloride above 200 mg/L.
3. The Stifling well appears to be able to sustain pumping rotes of up to 12 gallons
per minute. At this pumping rote the downgradient radius of influence of the well
would not extend to within 1000 feet of the sea.
4. Recommended water conservation measures will minimize the impact of seawater
intrusion in the future. Chloride monitoring is recommended to monitor future
water conditions. ' '
5. Based on the data avail~ble for review, it appears that there is a reasonable
probability that ptmaping at' the Stifling well will not cause significant degradation .-
from seawater inmasion to the aquifer.
