Dear Mr. Marks,
This letter report presents our analysis of hydrogeologic conditions at the property listed
above on Marrowstone Island, Washington. Our analysis addresses "relevant
components of an Aquifer Recharge Area Report per UDC 3.6.10e" as required by UDC
Groundwater Protection/Seawater Intrusion Amendments, March 3, 2003. Our
discussion with Jefferson County indicated that the "relevant components" were those
pertinent to exacerbating or causing seawater intrusion effects on neighboring wells
(personal communication, David Christensen, Jefferson County Division of Natural
Resources, 2003). Other components are not addressed in this report.
Our proposal of March 4, 2003 was authorized by Paul Marks on March 19, 2003. Our
work was performed, and this report prepared, in accordance with generally accepted
hydrogeologic practices at this time and place, for the exclusive use of Paul Marks, and
for exclusive application to the two primary wells on the subject property. This is in lieu
of other warranties, express or implied.
Propd'rty and Project Description
The Marks' property consists of about 8 acres on two parcels in the community of
Nordland on Marrowstone Island (Figure 1). The property currently has the following
dwellings and water-use attributes:
A two bedroom, one bath house (Johnson house) that is supplied off the dug well
· A one bedroom, one bath "cabin" that is supplied offthe dug well
· A front parcel of about 3 acres (976200402), some of which is irrigated with
water from the dug well
· A back parcel of about 5 acres (976200501) that is grazed and not irrigated. Two
unused wells are located on this back parcel (wells ACC057 and ACC059).

water & environmental consultiug
The property is for sale and the prospective new owner proposes to make changes to the
dwellings that will require a building permit. Changes to the structures proposed by the
buyer are:
Building a new two bedroom, 1.5-bath house on the front parcel that would be
supplied by the better of the two wells on the back parcel (well ACC059)
· Possibly moving the cabin to the back parcel and also supplying it off well
ACC059
· Maintaining the Johnson house as an "accessory dwelling", and maintaining the
water supply off of the dug well
If the cabin is moved, the total increase in bedrooms and baths on the combined parcels
will be 2 and 1.5, respectively (Table 1). If the cabin is not retained, the total increase in
bedrooms and baths will be 1 and 0.5, respectively. ~
As implied above, three wells exist on the two parcels. These wells, and othe'r wells
located within about 1000 feet, are shown on Figure 1. The Marks' wells are:
The dug well, which is located about 35 feet east of the JohnsOn house, i§ about 5 feet in
diameter and extends to 38 feet below land surface. It probably produces water from the
Qva aquifer with a water .level about 10.6 feet below ground surface on April 3, 2003.
Access to the well is through a 5fi x 5fi x 6.5ft deep concrete vault which rises 2.5 feet
above ground surface. The concrete vault serves as-an (unconventional) surface seal
which penetrates into glacial till. The till extends to below water level. Elevation of the
top of the concrete vault is 2.5 feet above local ground surface. Ground surface elevation
was estimated to be between 20 and 25 feet above mean sea level based on LIDAR data
provided by the County. Based on that elevation, the bottom of the well is between 13
and 18 fe~t below mean sea level, and the water level elevation is between 8 and 14 feet
above mean sea level. That water level is unusually high for Marrowstone Island and
indicates unusually high groundwater storage near the well.
'Well .ACC059 was drilled in 1995 near the center of the back parcel. Its well log
(attached) indicates it is 54 feet deep, has a surface seal to 18 feet depth, and penetrates
30 feet of surface soil and glacial, till. Water bearing sand and gravel of the Qva aquifer
was logged at 30 to 35 feet depth, and 44 to 50 feet depth. Bedrock was not encountered
within the drilled depth. The driller reported a water level 27 feet below ground in
October-1995. Water level in the well was 24.4 feet below the top of the steel casing
(2.2.6 feet below ground) on April 3, 2003. The 6-inch casing rises 1.8 feet above ground
surface and is capped with a pitless adaptor, although no pump is in the well. Elevation
of the top of the steel, casing was estimated at 39 feet above mean sea level based on
LIDAR data provided by Jefferson County. Based on that elevation, the bottom of the
well is at about 17 feet below mean sea level, and the water level is 15 feet above mean
sea level. The water level elevation in ACC059 ~is ~simi.'!ar to :..that~ ~o~th~ ;d? ~eI1

Well ACC059 was pump-tested in September 2000 by Bayview Pumps (see attachment).
A pumping rate of between 3.18 and 4.47 gallons per minute (gpm) was maintained fbr 2
hours. Water level in the well declined from a static level of 23.5 feet below the
measuring point to stabilize near the bottom of the well at 54 feet below measuring point
after about 70 minutes of pumping. Although the well experienced complete drawdown,
a pumping rate of over 3 gpm was maintained for the last hour of the test. The test was
not analyzed further for this report.
Well ACC057 was drilled in 1995 near the north end of the back parcel. Its well log
indicates it is 58 feet deep, has a surface seal to 18 feet depth, and penetrates 37 feet of
surface soil and glacial till. Water bearing sand and gravel of the. Qva aquifer was logged
at 37 to 42 feet depth. Bedrock (gray sandstone) was logged from 45 to 58 feet depth.
The driller reported a water level at 25 feet below ground in October 1995. The well is
welded closed and no water level was measured in April 2003. The 6-inch casing rises
2.2 feet above ground surface. Elevation of the top of the steel casing was estimated at
about 35 feet' above sea level based on LIDAR data provided by the County. Based on
that elevation, bedrock in the well was encountered about 10 feet below mean sea level at
this location. The well log reports a well yield of 0.3 gpm.
Hydrogeology
The hydrogeology of Marrowstone Island has been extensively studied, most recently as
a result of seawater intrusion concerns. The following description of the hydrogeology in
the vicinity of the project is derived from the well logs discussed above, a recent
reconnaissance, and Geology, Water ReSources, and Seawater Intrusion Assessment of
Marrowstone Island, Jefferson CoUnty, Washington, Washington State Department'of
Ecology Water Supply Bulletin No. 59, by Kirk Sinclair and Robert Garrigues, 1994.
Marrowstone Island rises gently to the east of Mystery Bay in the vicinity of the site.
The lower parcel occupies much of that west-facing gentle slope. The upper parcel is
relatively flat; and occupies part of the central portion of the island, although lands
further east are of higher elevation. The eastern shore of Marrowstone at that location is
a cliff, with nearby land surface elevations as high as 150 feet above sea level. The
distance between Mystery Bay and the eastern shore of the island is about 1600 to 1800
feet. The Marks' parcels span the western 600 to 700 feet of that distance.
Groundwater on Marrowstone is derived from infiltration of precipitation on the island.
Sinclair and Garrigues-(1994) estimated that in an average year 2.2 inches of water
infiltrate to recharge the aquifer. The volume of recharge water for the entire island was
estimated to be 730 acre-feet per year. Pammetrix and Pacffic Groundwater Group
(2000) estimated that recharge was about 5 inches in the average year' near the site.
Although the percent difference between those recharge estimates is large, the absolute
difference is only about 3 inches of water per year, which is within a .tTpical range of
precision for such calculations. The reason for the different- reehar_g?-estimates.w~ not
researched. The high groundwater head in the vic~y ~f ~he ~a~s !~a.!ls ~aY!indicate
i~ ~:' MAY 19 2003
unusually high recharge rates for the island. Infiltration through the relatively flat upper
parcel, and similar lands to the north and south, may contribute to this effect.
Once groundwater reaches the aquifer, it moves mostly laterally toward the island's
shorelines. In island environments, the fresh groundwater typically floats as a lens on top
of deeper groundwater that is saline. The fresh groundwater discharges to the sea along
the shorelines or is withdrawn by wells. Water that is extracted by wells and used inside
houses is mostly discharged back into the ground through septic syste, ms, thus resuming
its path toward the shorelines. Water used to irrigate lawns and other maintained
vegetation is added to the water that is transpired into the atmosphere from natural
vegetation and does not discharge to the sea:
Four geologic layers are involved with water movement and storage near the site.
Starting at land surface, they are as follows:
Surface soils are derived fi:om the underlying glacial till and were observed to be
moderately to poorly drained, organic rich, and relatively fine grained. Surface water
was observed in shallow depressions during April 2003, following a very wet March.
The upper parcel and nearby lands, comprising the central island terrace had extensive
areas of shallow groundwater and standing surface water. Detention of~ater within and
upon the surface soils of flat upland areas likely plays an imPortant role in maintaining
groundwater recharge in this vicinity.
Vashon till lies below the surface soils within a few feet of land surface. It is a very
dense, unsorted mixture of gravel and sand in a silt and clay matrix. Till is sometimes
called "hardpan" or "glacial concrete". Based on observations of shall.ow water and the
till penetrated by the dug well, the till has low permeability and causes retention of water
in surface soils dUring the wet season. The two on-site-well logs indicate that the till
extends to at least 30 feet below land surface.
Vashon Advance Outwash (Qva) deposits constitute an aquifer that underlies the till at
depths of 30 to 40 feet at this location. The deposit appears to be a stratified mixture of
sand and gravel, with occasional, clay lenses. The sand and ~avel strata constitute the
primary aquifer east of Mystery Bay, although the aquifer may have different zones,
separated by horizontal aquitards (low permeability layers) and by ._geologic
discontinuities of various orientations.' Groundwater in the aquifer at ~:~"~i~"i:

location. The bedrock has low permeability and tends to restrict groundwater storage ~[
movement - although wells develop small quantities of groundwater from fractures
within the bedrock when no alternative exists. On Griffith Point west of Mystery Bay,
bedrock is within a few feet of land surface, and directly underlies glacial till. Because of
Page 4
the absence of the Qva aquifer at that location, wells develop water from fractures in the
.bedrock. Bedrock was logged below 45 feet depth (estimated elevation of 10 feet below
sea level) in on-site well ACC057 where it underlies the Qva aquifer. Sinclair and
Garrigues (1994) report a well log (AAB083) that shows bedrock at an elevation of 20
above sea level near the Marks' property. That bedrock elevation is above the
potentiometric surface in any well in the vicinity - thus establishing the potential for
physical separation of the Qva aquifer zones by a buried bedrock ridge. The bedrock
ridge is generally depicted in Plate 5 of Sinclair and Gardgues (1994).
Groundwater Quality
The primary water quality concem that is related to water use is the possible increase in
dissolved constituents because of seawater intrusion. The discussion below focuses on
chloride concentration as an indicator of seawater intrusion. ~
Jefferson County recently classified all of Marrowstone Island as a high risk salt water
intrusion zone (SIPZ). The basis for the classification is the proximity of the shoreline to
almost all of the land on the island, and the presence of many wells on the island that
produce water that'contains more than 100 mg/I, chloride. -:
The Marks' dug well was sampled on April 3, 2003. Field analyses indicated that the
water was 54 degrees Fahrenheit, had a specific conductance of 465 uS,. a pH of 7.8, and
a chloride concentration of 45 mg/L (Iow). Although well ACC057 was not sampled, the
well log reports a chloride concentration of 30 to 45 mg/L. Well ACC059 was tested and
sampled in September 2000 and had a chloride concentration of 29.6 mg/L (see attached
Twiss Analytical report).
GroundwAter chloride concentrations in Marrowstone Island are reported in a map on the
Jefferson County website]. The Marks' .wells are not reported on that map; however,
many surrounding wells are. The data are shown on Figurel and indicate that the two
wells closest to the Marks' parcels'are low in chloride (<100 mg/L) but that many wells
in the vicinity have chloride concentrations greater than 100 mg/L. That data set,
combined wihh recent data from the on-site wells, indicates that the Marks' property is
underlain by a portion of the Qva aquifer that is not degraded by seawater intrUSion.
A high risk of seawater intrusion is indicated by the County's data on Griffith Point along
the western shore of Mystery Bay.' The Qva aquifer is absent 'in that area, and wells
produce water from the bedrock. Mystery Bay lies between Griffith Point and the Marks'
property. Because of the geographical and stratigraphic separation between the Griffith
Point bedrock aquifer and the Marks' property Qva aquifer, chati"~g;e~';'i~:~.41m~."d'"~i.s~

Page 5
A high risk of seawater intrusion is also indicated by the County's data for the eastern
shore of the island and for areas along East Marrowstone Road, all east of the Marks'
property. Wells in that area produce from a portion of the Qva aquifer that appears to be
in poor hydraulic continuity with the portion of the Qva aquifer under the Marks
property. The separation may be related to a ridge of bedrock that rises near-to or above
the potentiometric surface of the aquifer and thus splits the Qva aquifer into eastern and
western portions. Sinclair and Garrigues (1994) report that the bedrock elevation in well
AAB083 begins at an elevation of 20 feet above sea level. That elevation is above the
potentiometric surface, in any well in the vicinity - thus establishing the potential for
physical separation of the Qva aquifer zones by the buried bedrock ridge. The bedrock
ridge is generally depicted in Plate 5 of Sinclair and Garrigues (1994). Other evidence
for the isolated nature of the portion of the Qva aquifer near the Marks' residence
consists of high groundwater heads (8 to 15 feet above sea level) and low chloride
concentrations compared to the surrounding aquifer zones.
Seawater Intrusion
The thickness of the fresh groundwater lens is directly related to the amount of fresh
groundwater that floats on the saline groundwater below. As groundwater is extracted by
wells, the fresh water lens thins, and the saline water interface moves laterally inward and
upward toward pumping wells. Effects of pUmping are usually limited to establishment
of a new equilibrium position of the groundwater/sea water interface without actual
pumping of seawater by wells; however, under conditions where pumping water levels
are maintained below sea level for long periods of time, wells may begin to pump highly
saline water and become non-potable. At intermediate levels of effect, chloride
concentrations increase, particularly in wells near the shoreline, or in the deepest wells.
In the UI~? Groundwater Protection/Seawater Intrusion Amendments of March 3, 2003,
Jefferson County has identified that many locations on 'Marrowstone Islag.. al,are at~.n..'~..gf~
seawater intmsion. It is the purpose of the amendments to prevent de~.'.d~i~ti~fi
potable water resource.
Water. Use Analysis
This section presents estimates of water usc on the Mar~s' prope~ un~-h~te~[ ......
proposed ~tture conditions. The conditions are-s~zcd in ~able 1. Sin(~e all the
Marks'wells produce from the same aquifer and have similar bottom elevations, the
analysis does not differentiate between wells.
The analysis assumes that historical water use is near the high end of the per-capita range
cited by Sinclair and Garrigues .(1994): 150 gallons per day (gpd). per person'is the
assumed total water use. A high value was used because the Marks' property has old,
high-water-use fixtures and one of the largest lawns observed during our reconnaissance
on the island. For calculation purposes, we assume that the water supply for the property
Page 6
includes irrigation of 0.1 acres of shrubs and lawn, with an annual irrigation depth of 6'
inches per year. We also assume that the average bedroom houses 1.5 people. Under
those conditions, we expect that the Qva aquifer supplied a total of 675 gpd of water to
the property, of which an average of 45 gpd was for irrigation (Table 2).
Under the proposed conditions, it is assumed that fixtures in all dwellings will be
changed to low-flow varieties, which is assumed to result in a 25% reduction of in-house
water use. Conditions where irrigation remains unchanged, or reduces to zero are
analyzed. Total water use under the proposed conditions is estimated to reduce to 113
gpd per person. 'Given the increased number of bedrooms under the proposed condition,
slightly more to slightly less water will be used under the proposed conditions compared
to the historic conditions (Table 2), depending on whether the cabin is retained or not,
and whether groundwater continues to be used for irrigation or'not.
Although these calculations are approximate and contain several assumptions that may
not perfectly reflect historic or future conditions, they demonstrate that the proposed
change in land use can be approved without an increase in groundwater use. Key to
avoiding an increase in groundwater use is implementing water conservation measures
stipulated in the UDC and listed below in this report.
Impact Analysis
Based on the hydrogeologic conditions -at the property, potential impacts are limited to
wells in the local Qva aquifer zone. Impacts to wells currently experiencing high
chloride concentrations (wells on Griffith's Point and along East Marrowstone-Road) are
not likely because those wells draw water from aquifers that apparently have a low
permeability connection with the portion of the Qva aquifer from which the Marks' wells
draw water.
Impairment of the local wells will not occur if water use does not increase-and
groundwater recharge is preserved. The water use analysis indicates that water use
increase can be avoided or limited to a small increase. Groundwater recharge potential
can be protected through land and water use regulations (this is particularly important on
the nearly flat terrace near the center of the island, of which the Marks' upper parcel is a
part. Under these conditions, impacts to the local wells will be avoided.

Recommendations
We recommend that the Mandato . ^ctions listed for development in
and Ma~owstone Island S]PZ (UDC. 3.6.$ - Groundwater Protection/Seawater Intrusion
Page 7 g
Amendments) be required for approval of the proposed construction. These actions are
listed below along with other recommendations specific to these parcels and wells:
Water meters should be installed on the dug well and well ACC059. Meter
readings should be made in accordance with any coordinated effort for the island,
or at least quarterly.
2. Samples of water should be collected from each well and analyzed for chloride, in
coordination with any program coordinated by the County.
A minimum 1000 gallon storage-tank is required along with a pumP for well
ACC059 that is designed to provide the required flow at reduced drawdown in the
well (by increasing pumping time duration, and reducing pumping rate). The
maximum allowed pumping rate for each property is 3 gpm (Jefferson County
Water Conservation List, October 25, 2002). In add~ition, the volume pumped
from each Well is limited to 1000 gpd. Retrofitting the dug well with a new pump
and storage tank will not achieve much because the large diameter of the well
bore already provides a large in-ground storage capacity. The large well bore and
storage capacity naturally reduce drawdown spikes in the dug well.
Well ACC057 should be properly decommissioned, or converte~f to a monitoring
lOcation in'coordination with a County program, if desired.
5. All current water fixtures should be replaced with low-flow fixtures, and low-flow
fixtures should be used in all new construction.
Intercepted precipitation (roof drains, road runoff, etc) should be detained, and
infiltrated to the extent' possible, by approved means. (See the paragraph below
regarding use of catchment water for irrigation.)
T~e Water Conservation Measures List stipulates that well water cannot be used
to irrigate lawns or gardens, but that roof and other mn off can be retained in a
catchment and used for irrigation/ Depending on whether the cabin is retained or
not, this measure may be unnecessary to achieve a zero-net-impact based on the
water use analysis in this report. BecaUse of the limited volume of typical
catchments, implementing this measure could result in a reduction in total water
use on the Marks' parcels if implemented for new and existing water supPlies.
The owner may therefore wish to limit this restriction to the new construction, and
maintain limited irrigation capacity from -the. dug well, if 'allowed by the County
through this permitting process· An increase in irrigation could increase future
water use compared to historical uses and should be avoided.
