corporate and politic of the State of California ("Water Agency") and City of Petaluma, ("City"). The
Effective Date of this Agreement is the date the Agreement is last signed by the parties to the
Agreement, unless otherwise specified in Paragraph 7.1 (Term of Agreement).
RECITALS
A. The Water Agency provides potable water to the City via its transmission system.
B. The City utilizes groundwater pumped from the Petaluma Valley Groundwater Basin (Basin) as a
supplemental source of water supply and has the need to increase groundwater supply to bolster
local supply targets to augment regional supply from the Water Agency during periods of supply
curtailments caused by drought or emergency order conditions. The City wishes to evaluate
technical factors related to use of existing and future wells; conjunctive use of surface, recycled,
and ground waters; and water quality implications of groundwater utilization.
C. A comprehensive study of the Basin was last completed in 1982 by the Department of Water
Resources in cooperation with the Water Agency.
D. Water 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 develop an updated
assessment of the hydrogeology, geochemistry, and geology of the Petaluma Valley, including
development of a Geographical Information System (GIS) database, collection, and interpretation
of water quality data and streamflow measurements, estimates of groundwater recharge and
annual groundwater pumping, and development of a MODFLOW groundwater model.

Title: Evaluation of the groundwater resources of the Petaluma Valley
Cooperating agency: Sonoma County Water Agency (SCWA) and City of Petaluma
Period of project: 2014-2016
Geographic Scope: The Petaluma Valley in Sonoma County.
Problem: The city of Petaluma, located in the Petaluma Valley and home to about 12 percent of the
population of Sonoma County, faces growth in population and demand for water. Water supply is
provided primarily by water delivered via aqueduct from the Russian River; however, groundwater is a
vital supplemental source of water for the city of Petaluma and is the primary source of supply for
agriculture and domestic use by rural property owners. 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 groundwater resources. Water managers need to determine the likely
effects of future groundwater development in the Petaluma Valley and to identify efficient strategies
for surface-water/groundwater management that will assure the long-term viability of water supply.
Objectives: The primary objective of this study is to develop an updated assessment of the
geohydrology and geochemistry of the Petaluma Valley. This new information will establish the
framework for the future development of a coupled watershed/ groundwater -flow model for the
Petaluma Valley. The model will provide a tool to evaluate the hydrologic impacts of alternative
groundwater management strategies for the basin.
Relevance and Benefits: The proposed study will provide hydrologic information needed by Sonoma
County Water Agency, the city of Petaluma, and other management and regulatory agencies to better
understand the potential impacts of increasing groundwater use on groundwater levels, stream -
aquifer interaction, and water quality. The proposed study addresses USGS strategic science directions
"A Water Census of the United States" (accessed at URL:
http://Pubs.usgs.gov/circ/2007/1309/pdf/C13O9.pdf). The study will consider several priority U.S.
Geological Survey (USGS) water -resource issues including surface- and groundwater interactions,
conjunctive use of surface water and groundwater, effects of urbanization on water resources, and
hydrologic -system management.
Approach: Specific tasks will be: (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
groundwater -flow system based on the new data and the results of ongoing USGS geologic studies in
the basin; (4) development of a groundwater -flow model. The results of all four parts of the study will
be summarized in a USGS report.
Anticipated products: A USGS scientific investigation report (SIR) will describe the updated
geohydrologic characterization of the Petaluma Valley as well as the development, calibration, and
application of the groundwater -flow model. This groundwater -flow model is anticipated to be the first
step in the development of a coupled surface water/groundwater-flow model.

Water Resources Availability And Management In Sonoma County, California:
Phase 4— Evaluation Of The Groundwater Resources Of The Petaluma Valley
PROBLEM
The city of Petaluma, located in the Petaluma Valley and home to about 12 percent of the population
of Sonoma County, faces growth in population and demand for water. Water supply is provided
primarily by water delivered via aqueduct from the Russian River; however, groundwater is a vital
supplemental source of water for the city of Petaluma and is the primary source of supply for
agriculture and domestic use by rural property owners. 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 groundwater resources.
The two overarching groundwater management questions in the Petaluma Valley are:
1. What will be the effects of future groundwater development in the Petaluma Valley?
In particular, the increase in groundwater 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 Petaluma Valley
include iron, manganese, arsenic, nitrate, and high salinity.
What are efficient strategies for surface- water/groundwater management that will
assure the long-term viability of water supply in the Petaluma Valley? Historically,
individual groundwater users in the Petaluma Valley—municipal, agricultural, and
domestic — have proceeded independently in their utilization of groundwater. As
pumpage has increased, it is becoming clear that changes in pumpage in one location
can affect groundwater conditions elsewhere in the basin. Similarly, Russian River
water and groundwater 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, and increasing
environmental awareness in the region make integrated surface-water/groundwater
management essential. Management strategies may include enhanced groundwater
recharge projects, such as aquifer storage and recovery (ASR) projects or stormwater
retention/groundwater-recharge projects. Enhanced groundwater -recharge 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 Petaluma Valley and the development of a groundwater -flow model of the valley.
SCOPE
This proposal describes a cooperative project that will study and report on the geohydrology and
groundwater -management issues of the Petaluma Valley. This project will be the fourth phase of the
countywide work plan delineated in the U.S. Geological Survey (USGS) proposal for study of "Water
Resources Availability and Management in Sonoma County, California." That proposal describes
countywide 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
Resolution No. 2014-089 N.C.S. Page 13
water. This long-term cooperative plan involves geohydrological assessment of each of the county's
major groundwater basins, including the development of geographic -information systems (GIS) and
groundwater -flow models. Phase 1 addressed Alexander Valley, Phase 2 addressed the Sonoma Valley,
and Phase 3 addressed the Santa Rosa Plain watershed.
Phase 4 will be completed in two parts: (1) develop an updated assessment of the geohydrology and
geochemistry of the Petaluma Valley using available data and data that can be collected from existing
wells and (2) using the results from part 1, develop a groundwater -flow model. These new data and the
model will refine the understanding of the dynamics of groundwater flow in the valley The model will
be used to evaluate the hydrologic impacts of alternative groundwater -management strategies for the
valley. In addition, the assessment and model will be used to identify data gaps (e.g. locations where
depth -dependent water -quality and geologic data are needed).
RELEVANCE AND BENEFITS
The USGS cooperative program with the Sonoma County Water Agency (SCWA) has been developed to
study the integrated multi -basin management of groundwater resources in Sonoma County. As in the
first three phases, the proposed work in this phase will provide much of the hydrologic information
needed by SCWA to better understand the potential affects of increasing groundwater use on
groundwater levels, stream discharge, stream -aquifer interaction, and water quality. In particular,
municipalities in the Petaluma Valley (primarily the city of Petaluma), and other associated
management and regulatory agencies will benefit from this phase of the work. Through the
hydrogeologic characterization efforts associated with this study, which includes groundwater -level
monitoring, information and possible data sources could be identified to assist in the city of Petaluma's
efforts in complying with the California Statewide Groundwater Elevation Monitoring (CASGEM)
Program. The proposed study also will provide the information needed by SCWA and others to
efficiently utilize the County's surface- and groundwater resources. Researchers with the Central
Mineral and Environmental Resources Science Center (CMERSC) are currently studying the
geohydrologic framework of coastal basins in California, including the Petaluma Valley. The timing of
the proposed cooperative water -resource study in Petaluma Valley with the ongoing CMERSC study of
the coastal basins will allow researchers with California Water Science Center (CAWSC) and CMERSC to
collaborate and develop a more thorough understanding of the Petaluma Valley geohydrology than
would result from CAWSC and CMERSC working individually. In addition, combining the efforts of
CAWSC and CMERSC will result in a better product at a reduced total cost to the cooperators by
reducing any duplication of effort. The proposed study addresses USGS strategic science directions "A
Water Census of the United States" (accessed a URL:
http://Pubs.usgs.gov/circ/2007/1309/pdf/C13O9.pdf). This project will consider several priority water -
resource issues including surface- and groundwater interactions, conjunctive use of surface water and
groundwater, effects of urbanization on water resources, and hydrologic -system management. The
long-term plan for this cooperative program, after completion of groundwater -flow models of
individual basins, is to develop a model that interrelates surface water, both local and imported, with
the multiple groundwater 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.

GENERAL HYDROLOGIC DESCRIPTION OF THE PETALUMA VALLEY
The Petaluma Valley (fig. 1) is located in southern Sonoma County and is one of several valleys in the
Coast Ranges Geomorphic Province of Northern California defined by bordering northwest -southeast
trending mountains. The proposed study area stretches from Penngrove south to the Marin County
line and San Pablo Bay, encompassing about 94 of the approximately 146 square miles (miz) of the
Petaluma River Watershed. The Petaluma River and its tributaries provide the main surface drainage
for the area, flowing generally from north to south into San Pablo Bay. The Petaluma River had an
average discharge of about 300 cubic feet per second (cfs) during water years 1999-2008 at the USGS
gaging station 11459150 in the city of Petaluma. In comparison, the average discharge of the Russian
River at USGS gaging station 11467000 near Guerneville was about 2,000 cfs (U.S. Geological Survey,
2010).
The USGS (Cardwell, 1958) and the California Department of Water Resources (Herbst, 1982) have
completed studies of the Petaluma Valley. Cardwell 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. Herbst (1982) stated that the two major water -producing zones in the Petaluma
Valley 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.
The general direction of groundwater flow is from the uplands to the east and west of the valley
towards the center of the valley. Cardwell (1958) noted that the streams in the Petaluma Valley were
generally fed by discharge from groundwater and that most groundwater recharge is from direct
precipitation. As groundwater pumpage has increased, the stream -aquifer dynamics have likely
changed.
Water supply in the Petaluma Valley is met by combinations of surface -water delivery from the Russian
River and groundwater from local basins. Petaluma is the largest city in the valley with a population of
57,941 people as of April 1, 2010 (California Department of Finance, 2010). It utilizes primarily Russian
River water for water supply, but maintains wells as a supplementary source. Historically, the city's
annual groundwater production has ranged from 0 to more than 1,400 acre-ft/year (Dodson-Psomas
Engineers, 2007). For the 2009 calendar year, groundwater accounted for more than 12 percent (1,071
acre -ft) of Petaluma's water supply (Kim Rosmaier, California Department of Water Resources, unpub.
data, 2010). In addition, numerous private wells in the Petaluma Valley provide water for agriculture,
livestock, and domestic use.

The study will characterize the hydrogeology and geochemistry of Petaluma Valley by means of 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 on water -quality sampling; and (3) data interpretation and geohydrologic characterization
— including refining hydrologic budgets, and updating conceptual models of the groundwater -flow
system based on the new data and the results of ongoing USGS geologic studies in the basin; and (4)
development and application of a groundwater -flow model. The results of all four parts of the study
will be described in a USGS report.
Resolution No. 2014-089 N.C.S. Page 15
All water -level and water -quality data will be entered into the USGS NWIS (National Water Information
System) database. Approximately 10 percent of the number of environmental samples collected will be
added as quality -control samples. These samples will include blanks and replicates, and will be
targeted for selected constituents as needed. All GIS metadata will be documented according to USGS
guidelines (http://gio.usgs.gov/egis/metadata/).
1. Development of Geographic Information System (GIS)
The USGS will work collaboratively with SCWA and the city of Petaluma to develop a GIS database of
the Petaluma Valley. This work will build on the existing databases that have been developed for the
Petaluma Valley by SCWA, the city of Petaluma and the U5G5. Additional sources of data include the
California Department of Water Resources, California Department of Public Health, and the Sonoma
County Department of Health Services. The GIS will form the basis for all subsequent tasks, including
determination of needs for new data collection. The GIS developed for this study will include the
following information: drillers' logs; electric logs; historic groundwater levels; historic pumpage; land
use; aquifer tests and specific -capacity tests; and chemical analyses.
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 SCWA
technical staff. Sampling will focus on delineating the source and age of groundwater in the main
water—bearing zones in the Petaluma Valley and characterizing the current water quality. The sampling
will build on the recent water -quality data collected as part of the USGS Groundwater Ambient
Monitoring and Assessment (GAMA) program (Kulongoski and others, 2006; 2010). For this study,
water -quality analysis 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
and/or carbon-14 analyses will be used to provide information on groundwater age and travel time.
Specific analyses of constituents of particular concern, such as arsenic, iron, manganese, and nitrate
also will be conducted. Elevated concentrations of sodium and chloride associated with saltwater
intrusion from bay mud deposits bordering San Pablo Bay (Herbst, 1982) have been a concern in past
years and could once again become a concern with increasing groundwater pumpage. As such,
particular attention will be paid to physical parameters and inorganic constituents (specific
conductance, sodium, chloride, boron, bromide, and iodide) that could signal possible reemergence of
saltwater intrusion in the southern portion of the study area. Specifically, 10-20 wells will be sampled
per year for the first two years of the project. All wells will be analyzed at the USGS National Water
Quality Laboratory (NWQL) for major and minor ions; basic nutrients; trace metals; and stable isotopes
of oxygen and hydrogen. Selected wells would be analyzed for tritium/helium and/or carbon-14 age -
dating analyses. Sampling locations and analytes would be chosen based on a review of existing water -
quality data.
In addition to the basic suite of constituents proposed for sampling in the current proposal, there is a
broad range of additional water -quality sampling and analyses that could be conducted. These include
additional isotopes such as strontium, nitrogen, boron, and possibly more extensive carbon-14 and
tritium/helium analyses. The collected water -quality data will be evaluated to determine if additional
sampling is warranted. SCWA will then determine if funding is available for the sampling.
Resolution No. 2014-089 N.C.S. Page 16
3. Data Interpretation and Geohydrologic Characterization
The geohydrologic characterizations of the Petaluma Valley, based on previous USGS and DWR studies,
will be analyzed and updated based on new interpretations and data collected for this study. This will
involve reassessing the hydrostratigraphy and geometry of the water -bearing units quantifying the
distribution and quantity of recharge and discharge (including pumpage), and evaluation of
geochemical characterists of the basin. 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; quantify the groundwater budget; evaluate the dynamics of surface-
water/groundwater interaction; characterize the general geochemical characteristics and the sources
and ages of groundwater; and identify geochemical and hydrogeologic data gaps.
As part of this study, USGS researchers with CMERSC in Menlo Park, CA and Denver, CO, working
closely with project personnel from this study, will develop a geologic framework model of the major
water -bearing units in the Petaluma Valley. 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). We will use these data
along with newly collected geochemical data to reassess the hydrostratigraphy and geometry of the
major water -bearing units of the groundwater basin. GIS coverages of major water -bearing unit
geometries will be created as part of this task. This framework model will provide the starting point for
our reassessment of the geohydrology of the area and will be the foundation used to develop the
groundwater -flow model.
The California Department of Water Resources (DWR) maintains a monitoring network of nearly 20
wells in the Petaluma Valley. 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 groundwater levels and relations between climatic variables (precipitation) and water levels.
Recharge areas will be identified using topography, geologic and soils maps, groundwater -level
records, stable isotopes, and a seepage run on the Petaluma River. Estimates of annual recharge will be
made using data from a calibrated Basin Characteristic Model (BCM) (Flint and others, 2004).
Evapotranspiration along the creeks will be estimated based on vegetation types and densities and
depth to water. As much as possible, pumpage data will be compiled from the relevant entities. When
those data are not available, especially for historical periods, pumpage will be derived from land -use
and well -location data.
There will be a particular focus on collecting information on the changing dynamics of stream/aquifer
interaction along the Petaluma River as groundwater pumpage increases. Records from the USGS
Petaluma River gage (114591500), along with seepage runs, will provide historic and current
information to define gaining and losing reaches of the stream. Specific plans for seepage runs will be
made after historic data are reviewed and field reconnaissance completed. However, in general, two
seepage runs are planned: one in the Fall and the second in the Spring.
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 may affect the quantity of
potable water available. In particular, the magnitude and distribution of iron, manganese, arsenic,
nitrate, and salinity will be assessed.
Resolution No. 2014-089 N.C.S. Page 17
Gaps in the geochemical and hydrogeologic data will be identified using the available data compiled in
Task 1 and the new data collected in this task. These gaps may include identifying wells where depth -
dependent water -quality data are needed or locations where multiple -piezometer monitoring sites are
needed. If available, these additional data will help refine the three-dimensional characterization of
Petaluma Valley.
All the proposed water -quality samples will likely be collected from long -screened production wells
that do not give depth -dependent water -quality data. The USGS has specialized equipment and
procedures 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.
In the course of evaluating existing well data — predominantly production wells with only drillers 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 to thoroughly characterize a three-dimensional groundwater -flow system such
as the Petaluma Valley. Available data will be evaluated to determine the location and number of
multiple -well monitoring sites needed to better describe the complex geohydrologic conditions of the
Petaluma Valley.
4. Development and Application of Groundwater -Flow Model
Groundwater flow in the Petaluma Valley will be simulated using MODFLOW-NWT (Niswonger and
others, 2011). In general, the horizontal model domain will include the entire watershed; this will allow
the groundwater -flow model to be coupled at a later date with a watershed model. The bottom
boundary will be either bedrock or a depth where minimal water is contributed to the groundwater
system. The upper boundary will be the water table. At a minimum, the model will represent all major
water -bearing units in Petaluma Valley, including the Merced, Glen Ellen, and Recent and older
alluvium. The Petaluma Formation and Sonoma Volcanics may also be included. The results from the
lithologic and geologic modeling will be used to define the distribution of hydraulic parameters. The
results from BCM (Flint and others, 2004) will be used to estimate temporally and areally distributed
natural recharge. Pumping data and other stresses will be identified and quantified from data collected
as part of tasks 1 and 2. Both steady state and transient models will be formulated. The simulation
horizon of the transient groundwater -flow model will be determined after compiling and assessing
historic data.
The MODFLOW-NWT model will be calibrated systematically using PEST (Doherty, 2010) to water -level
and seepage data collected as part of tasks 1 and 2. It is likely that Tikhonov regularization will be used
to incorporate a priori knowledge of the groundwater system and singular value decomposition will aid
in identifying unique parameter estimates.
5. REPORTS
As currently planned, one USGS Scientific Investigations Report (SIR) would be completed as part of
this study. Frequent meetings, where possible by telephone and webex, and a website will be utilized
to facilitate communication and coordination with SCWA and the city of Petaluma.
