Second Amended Cooperative Agreement to
Provide Funding and Support Information for
Santa Rosa Plain Groundwater Study
This Agreement is made by, between, and among the Sonoma County Water Agency,
( "Agency "), and the County of Sonoma, City of Cotati, City of Santa Rosa, City of Sebastopol, City
of Rohnert Park, Town of Windsor, and Cal American Water Company, a California Corporation,
(collectively referred to as "Participants ").
RECITALS
A. Agency and Participants all utilize groundwater pumped from the Santa Rosa Plain Groundwater
Basin ( "Basin") and utilize the Basin for all or part of their municipal water supply.
B. A comprehensive study of the Basin was last completed in 1982 by the Department of Water
Resources in cooperation with the Sonoma County Water Agency.
C. Agency and the United States Geological Survey ( "USGS ") have proposed a study to evaluate the
groundwater resources of the Basin. The objective of the study is to: (1) develop an updated
assessment of the geohydrology, geochemistry, and geology of the Santa Rosa Plain, including:
development of a Geographical Information System database, identification of annual pumpage
quantities by sub -area, and estimated quantities and locations of annual recharge; (2) develop a
multi- aquifer groundwater flow model for Santa Rosa Plain; and (3) evaluate the hydrologic
impacts of alternative groundwater management strategies for the Basin.
D. The base cost of the study is estimated to be approximately $2,048,000 over five years and could
increase if the scope of work is expanded to include supplemental study activities. USGS has
indicated the study may be eligible for up to $625,000 in federal matching funds over the five -year
study period. Assuming the study qualifies for complete matching federal funds, a balance of
$1,425,000 would be paid by participating co- funding agencies over the life of the study.
E. Agency first entered into this agreement with USGS for the first year of the study, and Participants
agreed to share in the funding responsibility for that year pursuant to the terms and conditions of
the "Cooperative Agreement to Provide Funding and Support Information for Santa Rosa Plain
Groundwater Study" executed by Agency on August 17, 2005" ( "Original Agreement ").
F. The purpose of the Original Agreement was to (1) provide a funding mechanism by which
approximately $200,000 could be contributed to pay for the first year of the study of the Basin and
(2) establish a working relationship among technical staff, together with tools and protocols that
will be necessary for the success of additional studies as well as any future groundwater
management strategies.
G. After execution of the Original Agreement, each participant deposited with Agency its share for
Year 1 of the study -cost, as described in Attachment A of this Agreement.
Second Amended Cooperative Agreement to Provide Funding and Support Information for Santa Rosa Plain Groundwater Study 1
H. Since execution of the Original Agreement, Agency and Participants found it desirable to amend
the Agreement to provide additional funding for the second year of study as identified herein and
executed the First Amended Agreement dated December 14, 2006, in the amount of $333,266.
I. Agency entered into an agreement with USGS for the second year of the study and Participants will
share in the funding responsibility for that year.
J. Following technical review and discussion, and after later execution of the First Amended
Agreement, Participants have found it desirable to fund additional second year work proposed by
the USGS, including collection of high- resolution seismic- reflection data in the Santa Rosa Plain.
The cost of the additional investigation is $120,000. USGS will fund $60,000 and Participants will
fund $60,000, as described in Attachment A of this Agreement.
K. Agency and Participants agree it is in the public interest to work cooperatively with other entities
whose service areas or boundaries overlie the Basin.
L. Agency and Participants have negotiated a projected cost sharing for the study based on
groundwater usage and population served.
M. This Agreement provides for funding the first and second years only and neither Agency nor
Participants are obligated to participate in further studies or to provide funds in other years.
N. Upon execution of this Second Amended Agreement by all parties, the First Amended Agreement
will terminate and is superseded by this Second Amended Agreement.

Second Amended cooperative Agreement to Provide Funding and Support Information for Santa Rosa Plain Groundwater Study A-1
ATTACHMENT B
Study Description
Title: Evaluation of the ground -water resources of the Santa Rosa Plain
Cooperating agency: Sonoma County Water Agency (SCWA)
Period of project: 2006 -2010
Geographic Scope: The Santa Rosa Plain in Sonoma County.
Problem: The Santa Rosa Plain, home to approximately half of the population of Sonoma County,
faces growth in population and demand for water. Water supply is provided by a combination of
ground water and water delivered via aqueduct from the Russian River. Water managers face the
challenge of meeting the increasing water demand with a combination of Russian River water, which
has uncertainties in its future availability, and local ground -water resources. The water use decisions
by the different entities in the Santa Rosa Plain will have an impact on other ground -water users.
Water managers need to determine the likely effects of future ground -water development in the Santa
Rosa Plain and to identify efficient strategies for surface - water / ground -water management that will
ensure the long -term viability of water supply.
Objectives: 1) develop an updated assessment of the geohydrology and geochemistry of the Santa
Rosa Plain; 2) develop a multi- aquifer ground -water flow model for Santa Rosa Plain; and 3) evaluate
the hydrologic impacts of alternative ground -water management strategies for the basin.
Relevance and Benefits: The proposed study will provide hydrologic information needed by SCWA,
municipalities in the Santa Rosa Plain, and other management and regulatory agencies to better
understand the potential impacts of increasing ground -water use on ground -water levels, stream -
aquifer interaction, subsidence, and water quality. The study will consider several priority USGS
water - resource issues including surface- and ground -water interactions, effects of urbanization on
water resources, and hydrologic- system management.
Approach: (1) data compilation, utilizing a Geographic Information System (GIS); (2) new data
collection, focusing on water - quality sampling; (3) data interpretation and geohydrologic
characterization - including refining hydrologic budgets and updating conceptual models of the
ground -water flow system based on the new data and the results of ongoing USGS geologic studies in
the basin; and (4) simulation of ground -water flow in Santa Rosa Plain. A set of potentially important
additional data collection activities also are presented.
Anticipated products: a summary USGS report (WRIR), a fact sheet, and several journal articles.
Second Amended Cooperative Agreement to Provide Funding and Support Information for Santa Rosa Plain Groundwater Study B -1
Water Resources Availability and Management in Sonoma County, California:
Phase 2 - Evaluation of the ground -water resources of the Santa Rosa Plain
PROBLEM
The Santa Rosa Plain, home to approximately half of the population of Sonoma County, faces growth in
population and demand for water. Water supply is provided by a combination of ground water and
water delivered via aqueduct from the Russian River.
Water managers face the challenge of meeting the increasing water demand with a combination of
Russian River water, which has uncertainties in its future availability, and local ground -water
resources. The water use decisions by the different entities in the Santa Rosa Plain will have an impact
on other ground -water users.
The two overarching ground -water management questions in the Santa Plain are:
1) What will be the effects of future ground -water development in the Santa Rosa Plain? In
particular, the increase in ground -water demand resulting from urban growth and other
land use changes will affect water levels, recharge, surface -water discharge, and water
quality. Current regional water - quality concerns in the Santa Rosa Plain include iron,
manganese, and arsenic. There also is localized contamination from volatile organics
such as PCE. Increasing ground -water development may also induce land subsidence.
2) What are efficient strategies for surface- water / ground -water management that will
assure the long -term viability of water supply in the Santa Rosa Plain? Historically,
individual ground -water users in the Santa Rosa Plain - municipal, agricultural, and
domestic -- have proceeded independently in their utilization of ground water. As
pumpage has increased, it is becoming clear that changes in pumpage in one location
can have impacts on ground -water conditions elsewhere in the basin. Similarly, Russian
River water and ground water have historically been used as separate sources of supply,
but not explicitly managed in a linked manner. The increasing water demand, potential
reduction in availability of Russian River water, likely lowering of some maximum
contaminant limits (MCLs), and increasing environmental awareness in the region,
make integrated surface- water / ground -water management essential. Management
strategies may include aquifer storage and recovery (ASR) projects. ASR projects could
be operated on a seasonal basis to capture surplus winter flows or on a multi-year
climatic basis to store water for drought protection.
To properly address these two questions requires a thorough reassessment of the geohydrology and
geochemistry of the Santa Rosa Plain and development of a computer simulation model of the ground-
water flow system.
SCOPE
This proposal describes a cooperative project that will study and report on the geohydrology and
ground -water management issues of the Santa Rosa Plain. This project will be the second phase of the
county -wide work plan delineated in the USGS proposal for study of "Water Resources Availability
and Management in Sonoma County, California." That proposal describes county -wide water
management and the importance of the linkage between the Russian River basin - the main source of
water supply —and the other basins that are dependent, in part, on Russian River water. This long
term cooperative plan involves geohydrological assessment of each of the county's major ground -water
basins, including the development of geographic - information systems (GIS) and ground -water flow
models. The ongoing first phase of the work in the original proposal focuses on the Sonoma Valley and
Russian River system.
Second Amended Cooperative Agreement to Provide Funding and Support Information for Santa Rosa Plain Groundwater Study B -2
OBJECTIVES
The primary objectives of this second phase of the program are to: 1) develop an updated assessment
of the geohydrology and geochemistry of the Santa Rosa Plain; 2) develop a multi- aquifer ground-
water flow model for Santa Rosa Plain; and 3) evaluate the hydrologic impacts of alternative ground-
water management strategies for the basin.
RELEVANCE AND BENEFITS
As in the first phase of the USGS -SCWA cooperative studies of integrated multi-basin management of
ground -water resources in Sonoma County, the proposed work in this phase will provide much of the
hydrologic information needed by SCWA, municipalities in the Santa Rosa Plain, and other
management and regulatory agencies to better understand the potential impacts of increasing ground-
water use on ground -water levels, stream discharge, stream- aquifer interaction, subsidence and water
quality. The program also will provide the information and modeling tools needed by SCWA and
others to efficiently utilize the County's surface- and ground -water resources. This project will
consider several priority water - resource issues identified in the "Strategic Directions for the Water
Resources Division, 1999-2008," including surface- and ground -water interactions, effects of
urbanization on water resources, and hydrologic- system management. The long term plan for this
cooperative program, after completion of ground -water flow models of individual basins, is to develop
a model that interrelates surface water, both local and imported, with the multiple ground -water basins
for optimization of water resources utilization in Sonoma County. Such a model will provide
transferable tools for analyzing multi-basin water - management plans in other areas of the nation.
STUDY AREA
The Santa Rosa Plain is bounded to the southwest the Mendocino mountains and to the northeast by
the Sonoma and Mayacama mountains (fig. 1). To the southeast is a structural rise separating the Santa
Rosa Plain from the Petaluma Valley. The California Dept. of Water Resources (1982) suggests that the
Adobe Creek Anticline may act as the barrier between the two basins. To the northwest, a series of hills
separates the Santa Rosa Plain from middle part of Russian River system. The two basins are linked by
a gap in the hills southeast of Healdsburg (Caldwell, 1958).
GEOLOGIC FRAMEWORK OF THE SANTA ROSA PLAIN
Ongoing work by geologists at USGS indicates several geologic aspects of the Santa Rosa Plain that
may have important implications for ground water (Robert McLaughlin, USGS, Menlo Park, written
communication 2003). The Santa Rosa Plain is separable into two basins, the Cotati and Windsor
basins, filled to 2.5 -3.0 km in depth with Miocene to Holocene sedimentary deposits and volcanic rocks.
The Cotati basin is further subdivided into two sub - basins. These basins are floored with Mesozoic
rocks of the Franciscan Complex, and could include serpentinite of the Coast Range ophiolite and strata
of the Great Valley sequence.
On the western side of the Santa Rosa Plain, the basement is overlain by Pliocene marine strata and
nonmarine Pliocene - Pleistocene fluvial deposits. On the eastern side are Pliocene - Pleistocene fluvial
deposits that may overlap the age of the marine strata to the west. Volcanic rocks of Pliocene to
Miocene age underlie and are intercalated with parts of the marine and non - marine section. The age of
the buried part of the basin section is largely unconstrained.
Second Amended Cooperative Agreement to Provide Funding and Support Information for Santa Rosa Plain Groundwater Study B -3
Along the western margins of the Santa Rosa Plain are north - trending, down -to -the -east normal faults
of Pliocene and younger age, exposed only in a few places. Along the northeastern margins are the
active north - northwest trending Healdsburg and Rodgers Ck faults. The Windsor and Cotati basins
are separated by a basement high associated with the west - northwest trending, northeast - dipping
Trenton thrust fault, which is exposed only locally. The Cotati basin is subdivided by a deeper
basement ridge which is sub - parallel to the Trenton fault. The origin of this ridge is uncertain.
GENERAL HYDROLOGIC DESCRIPTION OF SANTA ROSA PLAIN
Water supply in the Santa Rosa Plain is met by combinations of surface -water delivery from the
Russian River and ground water from local basins. Santa Rosa is the largest city in the county (136,000
people in 1998) and has had the most rapid growth. It utilizes primarily Russian River water, but
maintains wells for emergency supply. Rohnert Park and Sebastopol currently use ground water for
most of their supply. Windsor receives water from the aqueduct as well as its own wells located near
the Russian River. Windsor also has wells within the Santa Rosa Plain for emergency supply. Cotati
primarily uses aqueduct water, but maintains wells to provide backup supply and meet peak summer
demands. SCWA operates three deep wells in the Santa Rosa Plain that are tied into the aqueduct. In
addition, there are numerous private wells in the Santa Rosa Plain that provide water for vineyards,
cattle, and domestic use.
The USGS (Cardwell, 1958) and the California Department of Water Resources (1982) have completed
studies of the Santa Rosa Plain. Caldwell identified the main water - bearing units to be the Pliocene
Merced Formation, the Pliocene -to- Pleistocene Glen Ellen Formation, and the Pleistocene and Recent
alluvium. The California Department of Water Resources (1982) stated that the two major water -
producing zones in the Santa Rosa Plain are the Merced Formation and the alluvial fan deposits
(Pleistocene to Holocene). Other potential water bearing units in the basin include the Pliocene
Petaluma Formation and Sonoma Volcanics.
Santa Rosa Creek, Mark West Creek, and the Laguna de Santa Rosa (Laguna) provide the main surface
drainage for the area. Santa Rosa and Mark West Creeks originate in the mountains to the east of the
Plain. The Laguna runs along the western margin of the basin in the northern part of the Plain and is
described by Caldwell (1958) as "a swampy, intermittent drainage course" that "discharges to the
Russian River through a narrow outlet." The USGS annual California water data summary states the
following about the Laguna. "The Laguna is a natural water channel and overflow basin connecting
the Santa Rosa Creek, Mark West Creek, and other smaller creeks with the Russian River. During
floods, directions of flow may be either to or from the Russian River, and the Laguna acts as a natural
regulator of floods on the lower Russian River." (Friebel and others, 2002)
Caldwell (1958) noted that the streams in the Santa Rosa Plain were generally fed by discharge from
ground water and that most ground -water recharge is from direct precipitation. As ground -water
pumpage has increased, the stream - aquifer dynamics have likely changed.
The general ground -water flow pattern is toward the center of the plain from the uplands to the east
and west.

APPROACH
The study has four principal tasks: (1) data compilation -- a GIS will be the primary means of
organizing data for archiving, searching, interrelating, and displaying hydrologic and related
information; (2) collection of new data, with a focus of water - quality sampling; (3) data interpretation
and geohydrologic characterization - including refining hydrologic budgets, and updating conceptual
models of the ground -water flow system based on the new data and the results of ongoing USGS
geologic studies in the basin; and (4) simulation of ground -water flow in Santa Rosa Plain. In this
document, the basic required components of these four principle tasks are delineated. In addition, a set
of potentially important additional data collection activities are presented.
1. Development of Geographic Information System (GIS)
The USGS will work collaboratively with SCWA to develop a GIS of the Santa Rosa Plain. This work
will build on the existing data bases that have been developed for the Sonoma Valley and Russian
River areas by SCWA, the Sonoma Ecology Center, and the USGS. The GIS will form the basis for all
later tasks, including determination of needs for new data collection. A partial list of data that would
be included in the GIS is provided in tabled.
2. New Data Collection
Water quality samples will be collected from selected wells, springs, and streams. Initially, existing
wells will be used and selected based on compiled data in the GIS and in consultation with County
technical staff. As described in the section on "Possible additional data collection," there would be
great value to drilling and installing multiple -well monitoring sites in the Santa Rosa Plain. Such
monitoring sites would allow for discrete depth- dependent sampling/ measuring of water quality,
water levels, and hydraulic properties.
Sampling will focus on delineating the source and age of ground water in the main water - bearing
zones in the Santa Rosa Plain and characterizing the processes of (potential) water - quality degradation.
The sampling will build on the recent water - quality data collected as part of the Groundwater Ambient
Monitoring and Assessment (GAMA) program. Water - quality analysis in this study will include basic
inorganic constituents and nutrients. The stable isotopes of oxygen and hydrogen will be used to
provide information on sources of recharge, and tritium /helium will be used to provide information
on ground -water age and travel time. Specific analyses of constituents of particular concern, such as
arsenic, iron, and manganese, also will be conducted. Specifically, we propose to sample
approximately 20 wells in each of the first two years of the project. All wells would be analyzed at the
USGS Central Lab for major and minor ions; basic nutrients; trace metals; arsenic, iron, and chromium
speciation; and stable isotopes of oxygen and hydrogen. Selected wells would be analyzed for
tritium /helium dating and /or carbon -14 /Carbon 13/12 analyses. Limited additional sampling would
be conducted in year 3. Sampling locations and analytes would be chosen based on the results from the
first two years of sampling. Other additional constituents that could be considered for sampling and
analysis are listed in the section on "Possible additional data collection."
Quality assurance plans will be developed. All new data collected in this study will be input into the
project GIS. In addition all these data will be entered into the USGS national data bases (NWIS or
GWSI).
Supplemental Work for Year 2:
Originally described under "Possible Additional Data Collection Activities" this supplemental work
will include the collection of high - resolution seismic- reflection data in the Santa Rosa Plain. The data
collected will be used to image basin structure and stratigraphy in critical areas as defined by current
interpretation of borehole, geologic, and geophysical information. In particular, the seismic- reflection
Second Amended Cooperative Agreement to Provide Funding and Support Information for Santa Rosa Plain Groundwater Study B -5
data will constrain the geometry and depth extent of the Trenton Ridge, a completely concealed
basement high that may restrict groundwater flow within the Santa Rosa Plain. The seismic- reflection
data will (1) constrain how close to the ground surface this impermeable basement ridge extends,
(2) evaluate whether the basement ridge folds or truncates sedimentary layers (aquifers) present above
the ridge and in the adjacent basins, and (3) test whether the Trenton thrust fault extends east across
the Plain, disrupting the sedimentary section. Project deliverables will include a data release, an
interpretive report, and a presentation describing the results.
3. Data Interpretation and Geohydrologic Characterization
The geohydrologic characterizations of the Santa Rosa Plain based on previous USGS and DWR studies
will be updated using data collected for this program and the results of modeling. This will involve
reassessing the hydrostratigraphy, quantifying the distribution and quantity of recharge and discharge
(including pumpage), and evaluation of basin water quality. The main goals are to develop an updated
representation of the hydrostratigraphy of the basin, obtain improved estimates of the hydraulic
properties of the water - bearing deposits, determine the sources and ages of ground water, characterize
the general ground -water quality characteristics, quantify the three- dimensional basin ground -water
budget, and evaluate the dynamics of surface - water / ground -water interaction. There will be
particular focus collecting information on the changing dynamics stream aquifer interaction along
Santa Rosa Creek, Mark West Creek, and the Laguna as ground -water pumpage increases. Note that
there are currently eight active USGS gaging stations in the Santa Rosa Plain, but none of these stations
have a long -term historical discharge record.
The California Department of Water Resources (DWR) maintains a monitoring network of nearly 40
wells in the Santa Rosa Plain. Water levels in these wells are measured semi - annually. The network
will be evaluated to determine if additional wells need to be added in order to provide adequate data
for continuing hydrologic studies. Data from the networks will be analyzed to assess any long -term
trends in ground -water levels and relations between precipitation and water levels.
As part of this study, USGS researchers in Geologic Discipline in Menlo Park will develop a geologic
framework model of the major water - bearing units in the Santa Rosa Plain. This framework model will
provide the starting point for our reassessment of the geohydrology of the area and initial development
of the ground -water simulation model This framework modeling will be conducted as part of a
geologic/ geophysical project being coordinated by Robert McLaughlin. The overall goal of that project
is to define the three- dimensional geology through areal geologic mapping, geophysical surveys, and
various topical studies (including geochronology, sediment transport patterns, and fault histories).
A particularly valuable benefit of the parallel geologic/ geophysical study in the Santa Rosa plain
relates to the possible additional data collection activities described later. These activities could
provide a wealth of new hydrologic and geologic information. The Menlo Park geologists and
geophysicists, whose salaries are already covered, would be interested and available to analyze such
new data if the costs of the field work and some student assistants were covered.
We will coordinate with the USGS geologic/ geophysical study to compile the most recent geologic and
soil mapping, geologic and geophysical well logs, and regional geophysical surveys. We will use these
data along with newly collected geochernical data to reassess the hydrostratigraphy of the ground-
water basins. GIS coverages of aquifer geometries will be created. As much as possible, pumpage data
will be complied from the relevant entities. When that is not available, especially for historical periods,
pumpage will be derived from land -use and well- location data. Recharge areas will be identified using
topography, geologic and soils maps, ground -water level records, and stable isotopes. Estimates of
annual recharge will be made using data from precipitation stations, ground -water levels, water
Second Amended Cooperative Agreement to Provide Funding and Support Information for Santa Rosa Plain Groundwater Study $ -6
chemistry, and environmental isotopes (tritium). Estimates of evapotranspiration along the creeks,
particularly the Laguna, will be estimated based on hydraulics and vegetation types and densities.
Chemical data from this study, combined with data from other sources, will be used to identify
geographic areas and depth zones where poor quality water exists and diminishes the quantity of
potable water available. Particular concerns with iron, manganese, and arsenic will be addressed.
Sampling for volatile organics compounds (VOCs) is not included as part of the basic data collection
for the study, but is listed as a possible additional task. If such sampling is undertaken,
characterization of the presence of low -level VOCs is in the regional ground -water system would also
be completed. Note that data on low -level VOCs for the Santa Rosa Plain has recently been collected as
part of the GAMA study.
4. Simulation Model of the Santa Rosa Plain
A ground -water simulation model using MODFLOW will be developed for the Santa Rosa Plain. The
model serves first as an analytic tool for synthesizing all available geohydrologic information. The
completed model then can be used as a management tool to assess the hydrologic impacts of
alternative water - management scenarios.
As noted above, the initial determination of model layering will be based very closely on the three -
dimensional geologic framework model to be developed by the USGS Geologic Discipline in Menlo
Park. Based on the previous hydrologic investigations, the model will be designed to simulate
conditions in the recent and older alluvium, the Glen Ellen Formation, the Merced Formation, and the
Sonoma Volcanics. The model development will be based very closely on the new geologic framework
work being conducted by the USGS Geologic Discipline. Data from the existing DWR water level
monitoring network will be used for model calibration. Both steady state and transient simulations
will be conducted. In the current modeling of the Sonoma Valley, 1974 is being used for a steady state
simulation. Because of the more extensive ground -water development in the Santa Rosa Plain, an
earlier period may have to be used for steady -state simulation. The transient simulation would then
extend from the steady state time period through to present conditions.
It will be important that the model adequately represent the interaction between ground water and the
major streams. As noted earlier, the surface water regime is likely to change as a result of changes in
ground -water conditions. It also will be essential to accurately represent the hydraulic linkage between
the Santa Rosa Plain and the adjacent basins - the middle Russian River system to the northwest, the
Petaluma Valley to the south, and the Bennett, Rincon, and Kenwood Valleys to the east. The model
will be a useful tool for testing the hydraulic impact of mapped faults in the basin using the Horizontal -
Flow- Barrier package. Finally, the model will be formulated with the Inter -Bed Storage package, in
order to have the capability of simulating subsidence.
The model will be particularly valuable for simulating the likely long -term hydrologic consequences of
alternative future scenarios. Scenarios would include a base case representing continued operation
under current conditions. Other scenarios would likely consider shifts in pumping locations (both
areally and vertically) and rates, ASR projects, and changes in delivery of Russian River.
The model can also be used in a particle tracking mode. This enables detailed evaluation of the
ground -water flow field and assessment of the potential advective transport of contaminants.

POSSIBLE ADDITIONAL DATA COLLECTION ACTIVITIES
In addition to the sampling and monitoring of existing wells and surface waters, there are additional
data collection activities that could provide invaluable geohydrologic data. Many of these activities
would take advantage of the available expertise in the USGS Geologic Discipline. These data collection
tasks are described briefly here. A more detailed presentation of the specifics of the monitoring well
drilling and coring is provided a separate document. Similarly detailed information, including costs,
on the other possible additional data collection activities also can be provided.
Drilling, coring, and logging deep (1200 -1500 ft.) drill holes and installation of multiple -well
monitoring sites -- This task is described in detail in a separate document. In the course of evaluating
existing well data - predominantly production wells with only driller's logs -- as part of the current
cooperative USGS -SCWA study, it has become clear that there is a crucial need for strategically located
deep multiple -well monitoring sites. Without at least a few such monitoring sites, it is not possible the
thoroughly characterize the three - dimensional ground -water flow system in the Santa Rosa Plain or in
the other Sonoma County basins. During the drilling of such sites, there would be detailed logging by
USGS geologists providing accurate characterizations of lithology. At selected sites continuous coring
would be conducted. The cores provide in situ sample of the materials and allow for direct assessment
of lithology, detailed stratigraphy, paleontology, tephra , paleomagnetic orientation, hydraulic and
thermal properties, and pore fluid chemistry. Once drilled, a broad suite of geophysical logs would be
conducted in the borehole. Finally, four -to -six individual piezometers would be installed at different
depths to allow for long term monitoring of depth- dependent water levels and water quality.
Additional water - quality sampling -- There is a broad range of additional water - quality sampling and
analyses that could be conducted, including low -level VOCs, additional isotopes such as strontium,
nitrogen, and boron. More extensive carbon and tritium helium analyses could also be considered.
Depth- dependent sampling - The USGS has specialized equipment for conducting depth dependent
water - quality sampling within production wells. Combined with flow -meter logging, this procedure
can quantify the different vertical chemical inputs that are contributing to the overall bulk water -
quality of water pumped from a production well.
Areal Geologic Mapping -This would be used to focus and improve the 1:24,000 -scale geologic
mapping around the Santa Rosa plain, to better carry surface stratigraphy into the third dimension, and
to better define the distribution and recency of faults.
Potential Field Geophysics - This would involve collection and interpretation of new detailed gravity
data along with existing high- resolution aeromagnetic data. This work would be used to improve
constraints on the shape of the basement (Franciscan) surface beneath the water bearing units, the
location, shape, and offset of faults within and bounding the Plain, and the distribution of mafic
volcanics of the Sonoma Group.
REPORTS
As currently planned a summary USGS report (WRIR), a fact sheet, and several journal articles would
be completed as part of this study. In addition to the formal reports, progress reports, frequent
meetings, and a website will be utilized to facilitate communication and coordination with SCWA and
other relevant stakeholders.

PERSONNEL
The project will require four senior hydrologists/ geographers (1/3 to 1/2 time per year) focusing on
the geohydrology, geochemistry, simulation modeling, and GIS. In addition, there would be a 1/4-
time field technician in years 1 -4. At least two researchers from the USGS Geologic Discipline will
work 1/8 to 1/4 time in years 1 and 2.
