ITEM TITLE RESOLUTION OF THE CITY COUNCIL OF THE CITY OF NATIONAL CITY AUTHORIZING THE MAYOR TO SIGN AN AGREEMENT WITH SWEETWATER AUTHORITY TO DRILL A TEST WELL AT EL TOYON PARK PREPARED BY Michael Long DEPARTMENT Public Works/Engineering 336-4580 EXPLANATION Sweetwater Authority desires to install an 800-foot deep test well at El Toyon Park for the purpose of monitoring the groundwater levels in the deep aquifer. Currently, Sweetwater Authority has two other monitoring wells in El Toyon Park, one is 150 feet and the other is also 800 feet deep. The purpose of this monitoring well is to do standard lithologic and geophysical logging, take core samples from selected depths and analyze them for physcial and chemical characteristics. The well itself will provide long term monitoring of depth dependent water levels and water quality. This information will be evaluated with other studies that have been done of the region to further understand the geology and hydrology of the San Diego area. The benefits will be substantial since this area relies on imported water from northern California and the Colorado River. The study will help implement a ground -water management plan that will decrease the problems associated with extended droughts. This agreement allows the third well to be installed, developed, and periodically monitored on City property by the Sweetwater Authority.

FAA til`J4L5 f4Cy SKr.h1IVA1EK AU111UK1 A tpJ UUG Summary Title: Hydrogeology of the San Diego Area, California Cooperating Agency: Sweetwater Authority Projects Chiefs: Wes Danskin, Clint Church (associate) Period of Project: FY02—FY04 Problem: No comprehensive geologic and hydrologic study has been made of the San Diego area. As a result it is difficult for state and federal agencies, water purveyors, and consultants to understand the effects of urbanization on the Iocal surface -water, ground -water, and biologic resources or to critique ideas and opportunities for additional ground -water development. This study will provide the integrated geologic and hydrologic knowledge necessary in this important and highly visible area of the United States. Objectives: The two primary objectives of this study ate (1) to develop an integrated, comprehen- sive understanding of the geology and hydrology of the San Diego area, focusing on the San Diego Formation and the overlying alluvial deposits, and (2) to use this understanding to evaluate expanded use of the alluvial deposits and San Diego Formation for recharge and extraction. Relevance and Benefits: This study will benefit local water purveyors by providing an improved understanding of the source of water to their production wells and the interaction of their production wells with near - surface ground water. Benefits toiothers in the San Diego area will be from having a comprehen- sive investigation of the 'primary aquifer in the region. Benefits to the nation include quantifying the resources of an important coastal city, and developing the background information necessary to manage a complex coastal biologic -hydrologic environment. This study will address five issues in the Strategic Directions for the Water Resources Division, 1998-2008. Sifically, the study will provide information about Issues 1, 2, 3, 8, and 9. Approach: To achieve the primary objectives requires (1) collection and analysis of new 'data, in particular new types of data such as naturally occurring stable and radioactive isotopes found in ground water; (2) exhaustive review of existing literature and interpretative work, (3) development of comprehensive concepts that integrate geologic, hydrologic, and water -quality data, (4) testing of these concepts with a regional ground -water flow model, and (5) evaluating regional water - management questions with a simulation -optimization model. The study involves four phases with each phase focusing on a specific coastal drainage basin. Data collection and analysis are parallel between phases, but each phase canbetailored to answer specific local questions for different cooperating agencies. Phase I, which has been funded by the Sweetwater Authority, focuses on the Sweetwater River drainage basin. Phases II —IV, which are presently unfunded, focus on the Otay, San Diego, and San Dieguito River drainage basins, respectively. Reporting is done via web and paper products for each phase, and a comprehensive USGS Professional Paper that summarizes results for the overall study.

As a result it is difficult for state and federal agencies, water purveyors, and consultants to understand the effects of urbanization on the local surface - water, ground -water, and biologic resources or to critique ideas and opportunities for additional ground -water development. This study will provide the integrated geologic and hydrologic knowl- edge necessary in this important and highly visible area of the United States. Although the San Diego area has a population of almost two million people, there is a paucity of data for the San Diego Formation and for the overlying alluvial deposits, which together comprise the predominate source of ground water in the area (fig. 2; Lluntley and others, 1998). Similarly, the interaction between ground water and surface water, which is found in four major rivers (San Dieguito, San Diego, Sweetwater, and Otay) and several small reservoirs, is not well described (figs. 1 and 3). Historic development of ground -water resources in the San Diego area for municipal use has been limited by the small areal extent of permeable deposits and by the modest recharge in this semi- arid region. As population has. continued to increase, however, there has been renewed interest in developing additional Iocal ground -water resources and using local permeable deposits for aquifer storage and recovery. Theability of local agencies to accomplish these goals has been limited by the lack of a detailed, comprehensive understanding of the hydrogeology of the area (City of San Diego, 2001). Objectives The two primary objectives of this four -phase study (fig. 3) are: (1) To develop an integrated, comprehensive understanding of the geology and hydrology of the San Diego Formation and the overlying alluvial deposits, and (2) To use this understanding to evaluate expanded use of the alluvial deposits and San Diego Formation for recharge and extraction. Secondary objectives include to; • Define the occurrence and geologic history of the San Diego Formation; • Define the hydrogeologic characteristics of the San Diego Formation and the overlying alluvial deposits, including areal and vertical variations; • Define the water -quality characteristics of the San Diego Formation and the overlying alluvial deposits; • Define the age and movement of ground water through the San Diego Formation and overlying alluvial deposits; and U.S. Geological Survey 2 Prepared 02-12-03 U4/18/2UU3 U8:58 FAA lily 425 7489 SWEETWATER AUTHORITY 142004 • Develop an integrated hydrogeologic framework for the area encompassing the San Diego Formation and the overlying alluvial deposits. Additional objectives are to integrate data and findings from this study with concurrent investiga- tions by the U. S. Geological Survey (USGS) Water Resources Discipline (WRD) for the Sweet- water Reservoir and by the USGS Biologic Resources :Discipline (BRD) in the Sweetwater River basin (fig. 4). Relevance and Benefits The Sweetwater Authority, a local water retailer, will benefit from phase I of the project which they have cooperatively funded. Phase I will provide an improved understanding of the sourceof water to their production wells and the interaction of their production wells with near -surface ground water in the riparian, alluvial channel of the Sweetwater River (fig. 4). Other water pur- veyors in the San Diego area will benefit from phases I, II, and III, which will provide new hydro - geologic data, and from phase IV, which will provide an integrated understanding of the primary aquifer in the region. Benefits to the nation include quantifying the resources of an important coastal city, and developing the background information necessary to manage a complex coastal biologic -hydrologic environment. This study will address five issues in the Strategic Directions for the Water Resources Division, 1998-2008. Specifically, the study willprovide information about Issue 1 (Effects of urbanization and suburbanization on water resources), Issue 2 (Effects of land use and population increases on water resources in the coastal zone), Issue 3 (Drinking water availability and quality), Issue 8 (Surface -water and ground -water interactions as related to water -resource management), and Issue 9 (Hydrologic -system management, including optimization of ground -water and surface - water use). Study Area The San Diego area of southern California lacks adequate local water supplies and each year as much as 90 percent of the demand is met by imported water from northern California or the Colo- rado River. Local precipitation in San Diego and the surrounding mountains is modest and what precipitation does fall, mostly as rain, nearly all during the winter months, quickly runs off to the Pacific Ocean. Several small reservoirs in the area (fig. 1) capture some local runoff, but they are used primarily to store imported water delivered in one of several large pipelines. Local ground- water resources are minimal and are found in small river channel deposits or in relatively low - yielding sedimentary rocks overlying nearly impermeable granitic and metavolcanic bedrock (fig. 2; Ellis and Lee, 1919). During multi -year droughts, both local and regional water supplies are reduced, and the San Diego area in particular is at risk of not being able to meet water demand, even that reduced by conservation efforts. Water rights for many of those providing imported water to the San Diego area are junior to others in California and the western United States. As a result, residents and businesses in the San Diego region risk being adversely affected both aesthetically and economi- cally by an extended drought. U.S. Geological Survey 3 Prepared 02-12-03 04/16/2003 08:58 FAX 619 425 7469 SWEE'1'WATER AUTHORITY 4005 To help minimize this risk and provide increased water supply during a drought, ground -water management plans are being developed to enhance the yield of the San Diego Formation, which is one of the few areally extensive aquifers in the area. The success of these plans is jeopardized by the meager hydrogeologic information that is available about the San Diego Formation (Boyle Engineering Corp., 1994; Boyle Engineering Corp. and Huntley, 1996). Also, operation of any new wells or artificial -recharge facilities needs to be optimally integrated with existing water -sup- ply infrastructure including reservoirs, regulated streams, wells, imported water, and demineral- ization facilities. In order to design and optimally operate new facilities, the hydrogeology of the area, and in particular the ground -water quality as it varies areally and with depth, need to be bet- ter understood. The San Diego Formation is located along the coastal plain in southwest San Diego County, and extends over an area of more than 120 square miles, from the coastal mountains in the east to San Diego Bay and the Pacific Ocean in the west, from La Jolla in the north to Tijuana, Mexico in the south (figs. 1 and 2). The formation is composed of thinly bedded sandstone and conglomerate, which originated as marine and non -marine sediment during the late Pliocene and early Pleis- tocene. The San Diego Formation ranges in thickness from about 100 feet to more than 800 feet and is overlain, apparently conformably, by about 100 feet of unconsolidated Quaternary deposits. The formation is underlain by as much as a 6,000 feet of Tertiary and Cretaceous sedimentary rocks, which in turn are underlain by metavolcanic and plutonic rocks (Elliott, 1970; Kuper, 1977). Most potable ground water in this stratigraphic sequence is extracted from the San Diego Forma- tion or the overlying Quaternary deposits (fig. 2). Ground water with a greater salinity is found in some parts of the San Diego Formation and in the underlying Miocene and Eocene rocks; how- ever, the distribution and source -Of the saline water is not known. Similarly, only limited informa- tion is available about 'the areal and vertical distribution of aquifer characteristics. Even the boundary between the unconsolidated deposits and the San Diego Formation, and between the San Diego Formation and underlying rocks is uncertain. Most hydrogeologic investigations of the area, including those by the USGS (Dwell, 1990; Even - son, 1989; Izllicki, 1983, 1985; Kaehler 1990; Kaehler and Hsieh, 1994; and Woolfenden, 1989) have focused on a specific subarea or project. Unlike in many other southern California basins, no comprehensive, integrative hydrogeologic work has been done except for an initial investigation by the USGS (Ellis and Lee, 1919) and a survey study by the California Department of Water Resources (1967). In 1998, a task force summarized the state of knowledge about the San Diego Formation and concluded that there was a paucity of data and a difficulty relating information from one area to another (Huntley and others, 1998). Geologic mapping of the land surface has been done for the entire study area and includes detailed maps of faults and geologic hazards (Marshall, 1979; Kennedy and Tan, 1975, 1977; Kennedy and Welday, 1980). The most recent geologic maps are beingprepared as GIS coverages by the Califomia Division of Mines and Geology, though these are not yet available electronically (M.P. Kennedy, oral commun., 2002). Mapping of offshore bathymetry is being done by the USGS (B.D. Edwards, oral commun., 2002) and by the Scripps Institute of Oceanography (S.P. Miller, written commun., 2002). Once these offshore data are processed, they will be available electroni U.S. Geological Survey 4 Prepared 02-12-03 04/16/2003 08:59 FAX 619 425 7469 SWEETWATER AUTHORITY 4 006 cally as GIS coverages and may aid in extending terrestrial geologic maps and stratigraphy onto the coastal shelf and into submarine canyons. Monitoring of surface water in the San Diego area is done by a variety of agencies including the USGS (fig. 5). Gaging stations are located on the major streams and reservoirs, and some water - quality data are available, including that collected as part of ongoing USGS studies of Sweetwater Reservoir (fig. 4; Majewski and others, 2002). Monitoring of ground water in the San Diego area has been done sporadically by the USGS and others (fig. 5; California Department of Water Resources, 1967). Data on more than 300 wells is available in the USGS electronic database, and information on another nearly 500 wells is avail- able on paper copy. Several deep borings in the area, made by oil companies, provide geologic information to depths of more than 5,000 feet (San Diego County Water Authority, written com- mun., 1998). Approach This study is designed as a sequence of phased investigations in order to most effectively gather detailed information about the largely unresearched and areally extensive San Diego Formation. Each phase focuses on gaining an understanding of part of the overall study area (fig. 3), and can be funded separately by different cooperating agencies that may have more focused questions or needs. As the study progresses, results from each phase will be integrated to create a comprehen- sive understanding of the San Diego Formation and overlying alluvial deposits. Phase I focuses on the Sweetwater River drainage basin and is funded by the Sweetwater Authority. Phases II and III focus on the Otay and San Diegp River drainage basins, respectively, and are presently unfunded. Phase IV integrates the results from phases I, II, and m as well as from three other ongoing USGS studies in the area (fig. 4). Phase I Phase I focuses on the Sweetwater River drainage basin (fig. 3). Small coastal drainage basins north of the Sweetwater River drainage basin are included in phase I. Phase IA, which has been initiated, involves limited water -quality data collection mostly from existing production wells in the city of Chula Vista (figs. 1 and 4). Phase IB involves expanded water -quality sampling includ- ing from two National City wells, development of a Geographical Information System, and pre- sentation of data on a website. Phase IC involves literature review, analysis of satellite InSAR data, aquifer tests, installation of a multiple -depth monitoring well, and preparation of a report. Scientific integration with three other ongoing USGS studies in the Sweetwater River drainage basin will add to the existing knowledge of surface -water quality and discharge (fig. 4). The first study, conducted by the USGS WRD, involves monitoring precipitation and surface water at Loveland and Sweetwater Reservoirs with the goal of identifying the effects of airborne contami- nation on a municipal surface -water supply (Majewski, 2001). The second study, also conducted by the USGS WRD, involves identifying ways to reduce the formation of disinfection by-products in water from Sweetwater Reservoir (Fram and others, 2001). The third study, conducted by the USGS BRD, involves monitoring biologic resources along the Sweetwater River and the effect of U.S. Geological Survey 5 Prepared 02-12-03 U4/10/L0U0 U ;UU 4L3 140:1 JWr.Y.1YA1Lx Autnuxl1Y ICJ 3.119 releases from the upstream Loveland Reservoir on habitat and breeding of the Arroyo Toad (Bufo Califomicus), a federally endangered species. Phase IA: Initial water -quality sampling and analysis. This phase, which was funded previ- ously by the Sweetwater Authority as a proof -of -concept investigation, focuses on gaining an ini- tial understanding of the water quality in part of the Sweetwater River channel (fig. 4). The primary objective of the Sweetwater Authority is to determine if production wells that penetrate the San Diego Formation are obtaining a significant amount of water from near -surface alluvial deposits. Ground water in the deposits supports riparian vegetation that has shown signs of stress in the vicinity of the wells. As of January 2003, all data have been collected and nearly all laboratory results have been received. Tritium results are expected to be received during spring 2003. Two briefings have been made to the cooperator about the data collected and preliminary conclusions. Tasks for phase IA include: • Task IA-1: Measure depth -dependent flowrate in selected production wells. Depth -dependent fiowrate was measured in three production wells (SDF-2, SDF-3, and SDF-5), wells that also were sampled for depth -dependent water quality in task IA-2. • Task IA-2: Collect depth -dependent samples of ground -water quality. Three wells were sampled:for depth -dependent water -quality (SDF-2, SDF-3, and SDF-5). Six samples per well were collected and analyzed for major and minor ions, selected trace elements, nutrients, dissolved oxygen, and stable isotopes of oxygen and hydrogen. Selected samples will be analyzed for carbon-14 and noble gases depending nn other lab results. • Task IA-3: Areal and depth distribution of ground -water quality. A single composite water sample was obtained from seven wells and was analyzed for major and minor ions, selected trace elements, nutrients, dissolved oxygen, - noble gases, tritium, carbon-14, and stable isotopes of oxygen and hydrogen. Ground -water samples were obtained from two wells known to be perforated in the alluvial aquifer (A-1 and A-4) and from two wells known to be perforated in the San Diego Formation (SDSW-2 and SDSW-4). Composite samples also were obtained from the wells used for depth -dependent sampling (SDF-2, SDF- 3, and SDF-5). A surface -water sample will be taken from the Sweetwater River. • Task IA-4: Data analysis. Data will be analyzed to define the water quality of the individual production zones of the San Diego Formation, the water quality of the overlying alluvial deposits, and the probable hydraulic interaction between the two. Phase IB: Expanded water -quality sampling and analysis. In phase 18, the areal extent of sam- pling done in phase IA will be expanded to include wells in National City and additional wells in Chula Vista that were not sampled previously. The focus of the areal sampling will be to collect both shallow and deep samples in order to extend three-dimensional water -quality characteristics throughout the coastal part of the Sweetwater River drainage basin. Although the eastern part of the drainage basin is expansive and an important source of runoff and eventual likely recharge to U.S. Geological Survey 6 Prepared 02-12-03 04/16/2003 09:01 FAX 619 425 7459 SWEETWATER AUTHORITY tQ.1009 that summarizes the findings in phases IA,1B, and IC. The audience for the report will be both the local water purveyors and thenational audience interested in investigating coastal hydrogeology with emerging techniques. • Task IC-1: Compile geohydrologic reports and data. This background infor- mation includes geologic maps and sections, geophysical data, offshore bathym- etry, water and oil well construction and lithologic data, ground -water -quality data, and surface -water discharge and quality data. These data are needed to fully interpret results from phases IA and IB. A comprehensive literature review will be done to augment information that was collected as part of phases IA and 1B. Electronically available USGS surface -water, ground -water, and water -qual- ity data will be reviewed and integrated into the GIS. Surficial geologic maps of the area will be obtained, digitized, and incorporated in the GIS. • Task IC-2: Analyze InSAR data. This type of remotely sensed data obtained from satellites can be used to help determine aquifer structure, presence of faults and other hydrologic barriers, areas of recharge and discharge, and how the aqui- fer responds to different pumping amounts and temporal distribution. This infor- mation will be combined with surficial geologic mapping to help define the three-dimensional geologicframework. • Task IC-3: Conduct aquifer tests. Define the hydraulic response of the San Diego Formation and its interaction with the alluvial system and water near the land surface. The Sweetwater Authority has planned packer tests, which isolate selected perforated depths in production wells, as part of their investigation of the effect of production wells on riparian vegetation. This opportunity likely will permit calculation of, Hydraulic properties for selected strata. The tests also may identify boundary conditions that can aid in inferring the presence of faults and stratigraphic interfaces. • Task IC-4: Install a multiple -depth monitoring well. In addition to standard lithologic and geophysical logging, core samples will be taken from selected depths and analyzed for physical and chemical characteristics. The well will be constructed to provide long-term monitoring of depth -dependent water levels and water quality. Additional wells will be drilled if additional funding becomes available. • Task IC-5: Prepare report. A USGS report or journal article will be prepared as a preliminary assessment of the San Diego Formation, emphasizing the geo- logic and hydrologic interrelations in the Sweetwater River drainage basin. Phase II Phase II extends the findings of phase I into the adjacent Otay River drainage basin, which is on the south side of the Sweetwater River drainage basin (fig. 3). The approach is similar to phase I, focusing primarily on integrating geologic data with ground -water -quality constituents that iden- tify the age, source, and three-dimensional movement of ground water. • Task II-1: Measure depth -dependent flow rate and collect depth -dependent water -quality samples from selected production or monitoring wells. Fol- U.S. Geological Survey 8 Prepared 02-12-03 V4/1U/ZUU3 U`J: UV FAA bLV 4Za 1469 Sw'Ei5'. AJ R AU'rt{JR11 the San Diego Formation and overlying alluvial deposits, this area is composed primarily of nearly impermeable crystalline rock. Therefore, most water -quality samples will be collected near the coast from wells in the thick sequence of permeable deposits (fig. 2). Electronic mapping and reporting capability will be developed to display the data and to better communicate the results to the cooperator and public. Depth -dependent flow and water -quality data will facilitate understanding the three-dirnensi onal ground -water flow system, and in particu- lar the interaction between the San Diego Formation and the overlying alluvial deposits in the Sweetwater River drainage basin. • Task IB-1: Develop a geographic information system (GIS) to interpret and present data and results. This mapping tool will be critically important in inte- grating complex, multi -layer data, in selecting wells to sample as part of phase II, and in facilitating hydrogeologic interpretatiions of the water -quality data. As well as the USGS, the locally supported SANGIS database has many of the GIS coverages needed for the area including hydrology and land use. San Diego State University has compiled coverages of pLuiemetric and land use data, in particu- lar for areas on either side of the United States Mexican border. The California Division of Mines has produced several surfieial geologic maps that will be digi- tized (M.P. Kennedy, oral commun., 2002). Offshore bathymetry data is available digitally from the USGS Geologic Discipline (B.D. Edwards, oral commun., 2002). • Task IB-2: Develop a website to display data collected in phases IA and IB. The GIS will be used to present geologic, hydrologic, and water -quality data col- lected in phases IA and IB. The ability of a website to be incrementally updated makes it flexiblev-.andlirghly responsive to cooperator needs. • Task IB-3: Measure depth -dependent flow rate and collect depth -dependent water -quality samples from selected production or monitoring wells. Fol- lowing measurement of the depth -dependent flowrate of the well, samples will be collected from specific depths and will be analyzed for the same constituents as in task IA-2 (major and minor ions, selected trace elements, tritium, and sta- ble isotopes of oxygen and hydrogen). Candidate wells include: SDF-1, SDF-4, two National City wells, A-4 because of anomalous dissolved oxygen detected in phase 1A, possibly A-1, A-2, and A-3, and two SDSW wells). • Task IB-4 Collect areal samples of ground -water quality. A single compos- ite water sample will be obtained from selected wells and will be analyzed for major and minor ions, selected trace elements, nutrients, dissolved oxygen, noble gases, tritium, carbon-14, and stable isotopes of oxygen and hydrogen. Wells to be sampled will be selected based on their broad areal distribution to build upon data collected in phase IA. Phase IC: Hydrogeologic interpretation. Phase IC initiates the background research necessary to fully interpret data collected in phases IA and IB, as well as data that will be collected in phases II and III. The long turnaround time required to receive water -quality results back from the lab as well as the desire to meet immediate cooperator needs requires the atypical order of initiating water -quality sampling prior to completing the background research. A report will be prepared U.S. Geological Survey 7 Prepared 02-12-03 04/16/2003 09:01 FAX 619 425 7469 SWEETWATER AUTHORITY r�o10 lowing measurement of the depth -dependent flowrate of the well, samples will be collected flora specific depths and will be analyzed for major and minor ions, selected trace elements, tritium, and stable isotopes of oxygen and hydrogen. • Task II 2: Collect areal samples of ground -water quality. A single composite water sample will be obtained from selected wells and will be analyzed for major and minor ions, selected trace elements, nutrients, dissolved oxygen, noble gases, tritium, carbon-14, and stable isotopes of oxygen and hydrogen. Wells to be sampled will be selected based on their broad areal distribution cov- ering the areal distribution of the San Diego Formation in the Otay River drain- age basin. Candidate wells include a multiple -depth piezometer that was previously sampled by the USGS (J.A. Izbicki, written commun., 1996). • Task II 3: Install multiple -depth monitoring wells. In addition to standard lithologic and geophysical logging, core samples will be taken from selected depths and analyzed for physical and chemical characteristics. The wells will be constructed to provide long-term monitoring of depth -dependent water levels and water quality. Ideally a total of 2-4 wells will be drilled through the San Diego Formation in the Otay River drainage basin. • Task 11-4: Data analysis acid interpretation. Data collected as part of phase II will be analyzed together with data from phase I in order to critique and expand the findings from phase I. The interpretation will include the regional geologic mapping, lithologic data from wells, surface and borehole geophysical data, InSAR data, GIS coverages, and historical surface -water and ground -water qual- ity data. • Task 11-5: Prepare mart_ Information from this phase will be reported on a USGS website, in a USGS report, or in a journal article. Phase III Phase III extends the findings of phases I and II into the adjacent San Diego River drainage basin, on the north side of the Sweetwater River drainage basin (fig. 3). Small coastal drainage basins north of the San Diego River drainage basin will be included as needed in phase III. The approach is identical to phase II, except more monitoring wells are needed for this larger area. • Task III-1: Measure depth -dependent flow rate and collect depth -depen- dent water -quality samples from selected production or monitoring wells. Following measurement of the depth -dependent flowrate of the well, samples will be collected from specific depths and will be analyzed for major and minor ions, selected trace elements, tritium, and stable isotopes of oxygen and hydro- gen. • Task 111-2; Collect areal samples of ground -water quality. A single compos- ite water sample will be obtained from selected wells and will be analyzed for major and minor ions, selected trace elements, nutrients, dissolved oxygen, noble gases, tritium, carbon-14, and stable isotopes of oxygen and hydrogen.

In addition to standard lithologic and geophysical logging, core samples will be taken from selected depths and analyzed for physical and chemical characteristics. The wells will be constructed to provide long-term monitoring of depth -dependent water levels and water quality. Ideally a total of 4-6 wells will be drilled through the San Diego Formation in the San Diego River drainage basin. • Task III-4: Data analysis and interpretation. Data collected as part of phase III will be analyzed together with data from phases I and II in order to critique and expand prior findings. The interpretation will include regional geologic mapping, lithologic data from wells, surface and borehole geophysical data, InSAR data, GIS coverages, and historical surface -water and ground -water qual- ity data. • Task III-5: Prepare report. Information from this phase will be reported on a USGS website, in a USGS report, or in a journal article. Phase IV Phase IV focuses on integrating data and interpretations from phases I, II, and III, each of which was focused on a specific drainage basin. Phase IV also adds a more quantitative interpretation of the ground -water system by developing an integrated water budget and a regional ground -water flow model. Evaluation of alternative water -management options is done via use of the flow model linked to a constrained_ optimization model. Hydrogeologic information from the San Die- guito River drainage basin, whiehis north of outcrops of the San Diego Formation (figs. 2 and 3), will be included as necessary. • Task IV-1: Develop a water budget. A comprehensive surface -water and ground -water budget will facilitate understanding of these systems as well as provide the necessary data for development of simulation and optimization mod- els_ , , • Task IV-2: Develop a regional ground -water flow model. This interpretative tool will facilitate a better understanding of how the surface -water and ground- water systems inter -relate and will provide a basis for quantitative analysis of regional water operations. Task IV-3: Develop a simulation -optimization model. A constrained optimi- zation model will be linked to the regional ground -water flow model in order to quantitatively analyze water -management plans. • Task IV-4: Evaluate optimal water management. Alternative water -manage- ment plans will be evaluated and compared with results from the simulation - optimization model. Specific topics to be analyzed can include aquifer recharge and recovery, effects of ground -water extraction, areas of potential new extrac- tion, and enhanced interaction between rivers and near -surface ground water. • Task IV-5: Prepare final report. A USGS Professional Paper will be prepared documenting and summarizing the geologic and hydrologic understanding of the U.S. Geological Survey 10 Prepared 02-12-03 04/16/2003 09:03 FAX 619 425 7469 SWEETWATER AUTHORITY t¢]012 San Diego area. The content will be regional in nature and focus on the findings from phase IV withcitations of prior publications from phases I, IL and III. Reports For phase I, two report products will be prepared_ First, a wPbsite will be developed to communi- cate the data and project information to the general public. Second, a Water -Resources Investiga- tion Report or journal article will be published to communicate the interpretative findings about the San Diego Formation to the cooperator, local water purveyors, and government agencies. This report will be in draft form by February 2004, approved by June 2004, and published by Septem- ber 2004:Technical results also will be communicated to the professional community via confer- ences. For. phases 11 and III, specific report products will be determined when cooperators and funding are identified, but will likely parallel those prepared for phase I. For phase IV, a professional paper will be the primary report product. Budget. Budget requirements for this project are listed below and in table I for phase I of the project, which has been funded by the Sweetwater Authority. Phase IA of this study was funded at $82,000 with the USGS contributing $20,000. Total cost for phases IB and IC is $421,000, with the total USGS contribution 'proposed to be $104,000, or about 25%. Proposed timeline. to com- plete phases IB and IC is 2 years, fiscal years 2003-2004, as shown in the attached workplan. Work can begin as soon as USGS funding and approval to proceed is made. 11 Prepared 02-12-03 EXHIBIT "B" 04/28/2003 14:27 9169656847 ACWA:JPIA PAGE 03/03 ADDENDUM to the Memorandum of Liability Coverage for the ASSOCIATION OF CALIFORNIA WATER AGENCIES JOINT POWERS INSURANCE AUTHORITY MEMBER AGENCY: Sweetwater Authority COVERAGE PERIOD: 10/01/02 - 10/01103 EFFECTIVE DATE: 04/28/03 ADDENDUM NUMBER: 04 Change in WHO IS COVERED The following entities are hereby added as Additional Covered Parties: City of National City, its officers, agents and employees, but solely with respect to those causes of action arising directly out of the activities covered by the Agreement to install deep groundwater monitoring wells into the shallow aquifer at El Toyon Park, A_P.N. 554-050-15, and subject to a $1,000,000 per occurrence and annual aggregate limit of liability_ Signed by: orized Represe 7 Date: April 28. 2003 MOLG190102 05/02/2003 10:55 FAX 619 425 7459 SWEETWATTER AUTHORITY 05/01/2023 15:13 91.696561347 ACWA:1PIA V'002 PAiac: 02/02 CE ' TlFICATE OF 1L.IABILriFY COVERAGE* for ttts9 ASSOCIATION OF CALIFORNIA WATER AGENCIES JOINT POWERS INSURANCE AUTHORITY *This: Certificate is issued ae a matter of information only and vailars no ril hts la)on the certificate holder_ This certificate does n0 t emend, extend or alter the covenDde afforded below.
