Davis County has the third largest county population in Utah, estimated at 300,827 in 2009 (Demographic and Economic Analysis Section, 2010). In 2009 Davis County residents made up 11% of Utah’s total population of 2,784,572 (Demographic and Economic Analysis Section, 2010). Based on projections made in 2005, the population of Davis County is expected to increase to 382,219 by 2030 (Demographic and Economic Analysis Section, 2005). This is an annual average increase in population of 1.2%; these estimates may be low—the projected average annual population increase in Davis County between 2000 and 2009 was 2.6% (Demographic and Economic Analysis Section, 2010). Davis County’s population will continue to grow, although the rate of population increase may be difficult to predict. The climate in the east shore area of Davis County is semi-arid with hot summers and moderately cold winters. However, due to the local topography and the large relief between the mountains and valley, the weather can be quite variable and is very much related to orographic effects and local weather patterns (Murphy, 1981). The mountains surrounding the valley typically receive substantially more precipitation and have cooler temperatures than the valley, and the southeast part of the county receives the most precipitation. 2 FACTUAL DATA Sufficient information is available to classify ground-water quality in the southern part of the east shore area aquifer system, Davis County, Utah. Data required to formally petition the Utah Water Quality Board were partly obtained from previously published studies. Most of the information required for classification is contained on maps and data tables submitted with this petition, including: • Plate 1 - Total-dissolved-solids-concentration map for the basin-fill aquifer. • Plate 2 - Ground-water quality classification map for basin-fill aquifer showing ground- water quality classification, well locations, and ground-water flow direction. • Plate 3a-c - Potential-contaminant-source map. In addition, provided along with this petition is the following previously released publication containing valuable information about the Davis County part of the lower Weber Sub-basin basin-fill aquifer: • Ground-water resources and simulated effects of withdrawals in the East Shore area of Great Salt Lake, Utah (Clark and others, 1990). • Ground-water resources and simulated effects of withdrawals in the Bountiful area, Utah (Clark, 1991). 3 GEOLOGIC SETTING The study area (figure 1) is in the southern part of the east shore area of Great Salt Lake in the Ogden Valley segment of the Wasatch Front Valleys section of the Great Basin physiographic province (Stokes, 1977). The east shore area is a basin lowland extending northward from the Salt Lake salient to the town of Willard, Box Elder County, and from the western margin of the Wasatch Range to the eastern shore of Great Salt Lake (Clark and others, 1990); this report covers the Davis County portion of the east shore area (figure 1). Because the area considered for this ground-water quality classification is part of the larger east shore area hydrologic system, we describe the geologic setting for the entire aquifer system. Elevation ranges from over 9000 feet (2700 m) for some peaks in the Wasatch Range to about 4200 feet (1280 m) at the shore of Great Salt Lake. The Weber and Ogden Rivers are the first and second largest streams in the east shore area, respectively, contributing 90 percent of the surface-water inflow (Clark and others, 1990, tables 3 and 4). The Ogden River is a tributary to the Weber River, as are Fourmile, Mill, and Burch Creeks in Weber County. Streams in Davis County are not tributaries to major river systems, but flow directly to Great Salt Lake. The major Davis County streams include Holms, Farmington, Ricks, Parrish, Centerville, Stone, and Mill Creeks (Clark and others, 1990, table 3). Dozens of other perennial, intermittent, and ephemeral streams flow westward from the Wasatch Range into the east shore area (Clark and others, 1990, table 4). Rocks in the Wasatch Range east of the east shore area consist primarily of Precambrian to Tertiary-age metamorphic and sedimentary rocks that are variably deformed and fractured, due to late Mesozoic to early Cenozoic thrust faulting. A wide variety of rock types exist north of Burch Creek, including the Precambrian Farmington Canyon Complex (described below) and 4 5 Paleozoic limestone, dolomite, shale, and quartzite (Crittenden and Sorensen, 1985; Yonkee and Lowe, 2004). South of Burch Creek, including most of Davis County, the Wasatch Range consists almost entirely of the Farmington Canyon Complex, a complex mixture of high-grade metamorphic and igneous rocks (Eardley, 1944; Bryant, 1984; Yonkee and others, 2000); these rocks include meta-ultramafic and mafic rocks, quartz-rich gneiss, biotite-rich schist, migmatitic gneiss, granitic gneiss, and pegmatite (Bryant, 1984; Yonkee and Lowe, 2004). Tertiary conglomerate crops out on the Salt Lake salient (Van Horn, 1981). The east shore area of Great Salt Lake is part of a north-south-trending structural graben that has been the site of accumulation of great thicknesses of sediment since its inception in early Tertiary time (Eardly, 1955). The active Wasatch normal fault at the base of the Wasatch Range forms the eastern margin of this depositional basin. Gravity, seismic, and drill-hole data indicate that the sediments filling this graben are locally up to 10,000 feet (3000 m) thick in some areas (Feth and others, 1966; Cook and others, 1967; Glenn and others, 1980; Zoback, 1983; McNeil and Smith, 1992). The basin fill likely includes an older sequence of tilted, Eocene to Oligocene strata consisting of a mixture of conglomerate, sandstone, reworked tuff, and minor lacustrine limestone similar to those preserved beneath parts of eastern Great Salt Lake (Constenius, 1996) and locally exposed on Antelope Island (Willis and Jensen, 2000). These older basin-fill deposits are overlain by Miocene to Pliocene rocks that are generally assigned to the Salt Lake Formation and consist of heterogeneous mixtures of poorly consolidated sedimentary rocks and reworked tuff (Miller, 1991). This Miocene to Pliocene basin fill is, in turn, overlain by less consolidated Quaternary basin-fill and surficial deposits of predominantly fluvial, lacustrine, and deltaic origin (Feth and others, 1966). The Quaternary basin-fill sediments are the primary focus of this report because they comprise the principal ground-water aquifers. 6 The study area is within the hydrologically closed Lake Bonneville basin, and water flowing into this basin generally leaves it only by evapotranspiration. The Lake Bonneville basin has been an area of internal drainage for much of the past 15 million years, and lakes of various sizes have existed in the area during most of that time (Currey and others, 1984). Due to this history of deep-lake cycles interspersed with periods when lakes stood at low levels or were not present, the Quaternary basin-fill deposits consist of complexly interfingering, overall westward-fining bodies of gravel, sand, silt, and clay deposited in lacustrine and fluvial environments (Feth and others, 1966; Sprinkel, 1993). The Quaternary lacustrine and fluvial basin-fill deposits over much of the east shore area of Great Salt Lake can be divided into a lower interval, the Delta aquifer; a middle confining interval; the Sunset aquifer; and an upper confining interval (Feth and others, 1966). The lower interval was deposited partly in a marginal lacustrine environment and consists mostly of thin- bedded silt and fine sand (Sprinkel, 1993). The Delta aquifer consists mostly of fluvial, interbedded cobble to pebble gravel and gravelly sand. The middle confining interval consists mostly of thin-bedded silt and fine sand, with some layers of pebbly sand, deposited in marginal lacustrine and fluvial environments (Sprinkel, 1993). The Sunset aquifer consists of pebble gravel, pebbly sand, and well-sorted medium to coarse sand of fluvial origin. The upper confining interval consists mostly of thin-bedded silt and sand likely deposited in a brackish lacustrine environment. The deposits forming each of these aquifers gradually thin and become increasingly finer grained away from the canyon mouths. 7 PREVIOUS STUDIES Dennis and McDonald (1944) conducted an early study of ground-water conditions in the east shore area of Great Salt Lake. Thomas and Nelson (1948) studied the geology and ground- water conditions in the vicinity of Bountiful. Dennis (1952) evaluated ground-water recharge in the east shore area. Hamblin (1954) studied the geology and ground-water conditions in northern Davis County. Feth and others (1966) conducted a comprehensive study of basin-fill deposits and hydrogeologic conditions in the northern Davis County and Weber County portions of the east shore area. Smith (1961) provided basic data on water levels and ground-water quality for the east shore area, and Smith and Gates (1963) evaluated changes in ground-water quality and water levels based on that data for the (1953-61) time period. Bolke and Waddell (1972) mapped ground-water quality and evaluated changes in water levels and ground-water quality in the east shore area for the (1960-69) time period. Clyde and others (1984) constructed a ground-water model, which they used to evaluate the potential for diverting water from the Weber River at the mouth of Weber Canyon for use as a source of artificial recharge for the Weber Delta area. Clark and others (1990) re-evaluated ground-water conditions in the Weber Delta sub-area of the east shore area and constructed a computer model for the northern Davis County and Weber County portions of the east shore aquifer to evaluate the effects of ground- water withdrawals. Clark (1991) re-evaluated ground-water conditions and constructed a ground-water model for the Bountiful sub-area of the east shore area. Nelson and Personius (1993) mapped the surficial geology of Weber and Davis Counties. Anderson and others (1994; see also Anderson and Susong, 1995) mapped ground-water recharge and discharge areas for the principal aquifers along the Wasatch Front, including aquifers in the Weber Delta district. Gates (1995) provided a description and quantification of ground-water basins along the Wasatch 8 Front, including a discussion of how water budgets changed from one ground-water study to the next. Yonkee and Lowe (2004) summarized ground-water conditions in the Ogden 7.5-minute quadrangle. Lowe and others (2003) described an aquifer storage and recovery project in Davis County near the mouth of Weber Canyon. Lowe and others (2004) evaluated ground-water sensitivity and vulnerability to pesticides for the principal aquifers in the east shore area of Great Salt Lake. Burden and others (2005) described changes in ground-water conditions in Utah, including the east shore area, from 1975 to 2005. Yidana and others (2010) developed a water budget and evaluated ground-water supply to wetlands in the Farmington Bay area of Davis County. GROUND-WATER CONDITIONS Basin-Fill Aquifers Because the basin-fill aquifer within the study area is part of the larger east shore hydrologic area, we include a description of the east shore aquifer system that includes areas outside Davis County. The east shore aquifer system can be divided into two somewhat separate hydrologic areas, the Weber Delta sub-area and the Bountiful sub-area (figure 2), both of which are in Davis County. The Weber Delta area is about 40 miles long (60 km) and 3 to 20 miles (5- 30 km) wide, and extends from the Wasatch Range westward to the Great Salt Lake, and from Willard, in Box Elder County southward to Centerville (figure 2) (Feth and others, 1966; Clark and others, 1990; Gates, 1995). The Bountiful area covers about 40 square miles (100 km2) extending from northern Centerville to the Salt Lake County line (figure 2) (Thomas and Nelson, 1948; Clark, 1991). 9 10 Important ground-water resources in the east shore area exist in unconsolidated to semiconsolidated Quaternary basin-fill deposits (Feth and others, 1966; Clark and others, 1990). These deposits include relatively coarse-grained alluvial sediments near the mountain front, and finer grained lacustrine and alluvial sediments westward away from the mountains (Feth and others, 1966; Bolke and Waddell, 1972; Clark and others, 1990) (figure 3). Deeper ground water in the east shore aquifer system is predominantly confined, but unconfined conditions exist locally in recharge areas along a narrow band at the base of the Wasatch mountain front (figures 3 and 4) (Anderson and others, 1994). Feth and others (1966) delineated two principal aquifers, the Sunset and Delta, in the central part of the Weber Delta sub-area. The Delta aquifer is the primary source of ground water for the Ogden area and is composed mostly of coarse-grained, pre-Bonneville fluvial and deltaic sediments (Clark and others, 1990). The top of the Delta aquifer is 500 to 700 feet (150-200 m) below ground surface in the Ogden area, and the aquifer is about 50 to 200 feet (15-60 m) thick (Feth and others, 1966). The shallower Sunset aquifer has a lower permeability and is used to a lesser extent as a source of ground water. The top of this aquifer is 200 to 400 feet (60-120 m) below ground surface in the Ogden area, and this aquifer is about 50 to 200 feet (15-60 m) thick (Feth and others, 1966). Fine-grained confining intervals overlie both aquifers away from the mountain front. A shallow unconfined aquifer is commonly found above the upper confining beds within Quaternary surficial deposits (Clark and others, 1990). Tertiary basin fill deeper than about 1500 feet (450 m) is commonly more lithified and less permeable, contains poorer quality water, and is not considered an important ground-water source (Clark and others, 1990). Three much more poorly delineated confined aquifers, the shallow, intermediate, and deep “artesian” aquifers, are present in the Bountiful sub-area; depths to the tops of these aquifers range from 60 to 250, 250 11 12 13 to 500, and greater than 500 feet (20-80, 80-150, and greater than 150 m), respectively (Thomas and Nelson, 1948). The ultimate source of ground water recharging the east shore aquifer system is precipitation in the drainage basin (Clark and others, 1990). Recharge enters the east shore aquifer system through channel seepage along losing stretches of streams; seepage from irrigated fields, lawns, and gardens; direct infiltration of precipitation; and subsurface inflow from bedrock of the Wasatch Range (Thomas and Nelson, 1948; Clark and others 1990). Most recharge takes place in the primary recharge area along the mountain front, especially near the mouth of Weber Canyon (Anderson and others, 1994). Subsurface inflow from bedrock along the mountain front and seepage from the Weber River and other perennial streams are probably the dominant recharge sources (Thomas and Nelson, 1948; Feth and others, 1966). Discharge from the east shore aquifer system includes flow into gaining stretches of streams and to small springs, water-well withdrawal, evapotranspiration of shallow ground water, and ground-water flow to Great Salt Lake (Thomas and Nelson, 1948; Feth and others, 1966). Water-well withdrawal and flow to gaining streams and springs are the main discharge components (Clark and others, 1990). Ground-water flow in the east shore system is generally westward from recharge areas near the Wasatch Range toward Great Salt Lake (Thomas and Nelson, 1948; Feth and others, 1966). For the Weber Delta area, the horizontal hydraulic gradient for deeper wells in the Delta aquifer is about 5 feet per mile (1 m/km) in most areas, and the horizontal hydraulic gradient for shallow wells in the Sunset aquifer is about 10 feet per mile (2 m/km) (Feth and others, 1966). 14 The horizontal hydraulic gradient for wells in the shallow artesian aquifer in the Bountiful area is also about 5 feet per mile (1 m/km) in most areas (Thomas and Nelson, 1948). The vertical hydraulic gradient in the east shore aquifer system is generally downward in recharge areas near the mountain front, and generally upward where confined conditions exist west of the mountain front, but vertical flow is probably relatively slow through low-permeability confining layers (Clark and others, 1990). Transmissivity values for confined parts of the Weber Delta area aquifer system range from 270 to 40,000 feet squared per day (25-3700 m2/d), based on 17 aquifer tests conducted between 1944 and 1956 (Feth and others, 1966, table 8). Transmissivity values for unconfined conditions near the mountain front in the Weber Delta area range from 4000-5300 feet squared per day (370-500 m2/d), based on three aquifer tests conducted between 1944 and 1956 (Feth and others, 1966, table 8). Elastic storage coefficients for the Weber Delta area of the east shore aquifer system range from about 0.002 to 0.00007, based on tests conducted between 1944 and 1956 (Feth and others, 1966, table 8). Specific yields, related to dewatering of pore space, are likely in the range of 0.25 to 0.07 for the Weber Delta area, based on observed porosities and limited recharge tests (Feth and others, 1966). The Bountiful area aquifers likely exhibit similar values. Seasonal ground water levels in the Weber Delta district generally rise in the spring during net recharge and decline in the summer, with greatest declines near the mountain front (Thomas and Nelson, 1948; Clark and others, 1990). Long-term water levels in the east shore aquifer system for most areas have declined slightly over time, probably related to increased withdrawals from wells for municipal and industrial use (Clark and others, 1990). From 1953 to 15 1985, ground-water levels declined an average of 27 feet (8 m) for wells in the confined part of the aquifer system in the Weber Delta area, with a maximum drop of 50 feet (15 m) near the principal pumping center for the aquifer system (Clark and others, 1990). From 1953 to 1985, water levels in the unconfined part of the aquifer system in the Weber Delta area declined as much as 40 feet (12 m) in wells near the mouth of Weber Canyon (Clark and others, 1990), indicating that ground-water mining is a concern. The trend in declining water levels in the east shore aquifer system does not appear to have slowed; Burden and others (2005) documented water-level declines of up to 36.7 feet (11.2 m) from 1975 to 2005 (figure 5). Burden and others (2005) attribute the rise in water levels in the Plain City and North Ogden areas from 1975 to 2005 (figure 5) to decreased local pumpage. Ground-Water Quality from Previous Studies Ground-water quality in the east shore area aquifer system is generally good, with total- dissolved-solids (TDS) concentrations ranging from 92 mg/L in the Weber Canyon area to 9800 mg/L in the southwest North Ogden area, based on ground-water quality data from Smith (1961, table 3), Smith and Gates (1963, table 4), Feth and others (1966, table 9), Bolke and Waddell (1972, table 2), Plantz and others (1986, table 5), Clark and others (1990, table 13), and Anderson and others (1994, table 2). Geochemically, ground-water types in the east shore aquifer system are calcium-magnesium-bicarbonate, sodium-bicarbonate, sodium-chloride, and no predominant type (Smith and Gates, 1963; Feth and others, 1966; Bolke and Waddell, 1972; Clark and others, 1990). The calcium-magnesium-bicarbonate type is the predominant ground- water type in the east shore area of Great Salt Lake, and generally contains less than 300 mg/L TDS (Feth and others, 1966, figure 14). The sodium-bicarbonate type ground water is along the 16 17 eastern margin of Great Salt Lake in the northern and southern parts of the study area, and generally contains less than 400 mg/L TDS (Smith and Gates, 1963). The sodium-chloride type occurs mostly north in the southwest North Ogden/northeast Plain City area and in a few areas along the shore of Great Salt Lake, and contains from 500 mg/L TDS at the mouth of Ogden Canyon to more than 9,000 mg/L TDS in the southwest North Ogden area (Smith and Gates, 1963, figure 8; Feth and others, 1966, figure 14). Mixed-type water exists in an area extending westward from Ogden Canyon and in the Bountiful/North Salt Lake area, and contains from 500 to 1000 mg/L TDS (Smith and Gates, 1963, figure 8; Feth and others, 1966, figure 14). Concentrations of organic solvents, such as toluene and trichloroethane, exceeding ground-water quality standards (U.S. Environmental Protection Agency, 2010) have been identified in the shallow unconfined aquifer in the Hill Air Force Base area south of Riverdale and are currently being remediated (Dalpias and others, 1989). Smaller plumes may also be present at other sites in the area, such as the Ogden Defense Depot west of Ogden. Ground-water quality data from Smith (1961, table 3), Smith and Gates (1963, table 4), Feth and others (1966, table 9), Bolke and Waddell (1972, table 2), Plantz and others (1986, table 5), and Clark and others (1990, table 13) indicate that water samples from wells have exceeded U.S. Environmental Protection Agency (2010) secondary ground-water quality standards for manganese in four wells in western Weber County; additionally, five wells have yielded ground-water with high nitrate concentrations (greater than or equal to the ground-water quality standard of 10 mg/L for nitrate). 18 GROUND-WATER QUALITY CLASSIFICATION DATA To facilitate this ground-water quality classification, the Utah Geological Survey used data from 20 sampled wells. The Utah Department of Epidemiology and Laboratory Services analyzed ground water from all of the wells for general chemistry, dissolved metals, and nutrients (appendix A); of these wells, ground water from two wells was analyzed for organics and pesticides and ground water from one well was analyzed for radionuclides (appendix A). The samples were also measured for field parameters (specific conductance, dissolved oxygen, pH, and temperature). These data were augmented by specific conductance, total-dissolved- solids concentration, and selected data from other ground-water constituents from 39 samples collected from public-supply wells as reported by the Utah Division of Drinking Water and 64 samples from the U.S. Geological Survey (USGS) (appendix A). The Utah Water Quality Board’s drinking-water quality (health) standard for total dissolved solids is 2000 mg/L for public-supply wells. The secondary ground-water quality standard is 500 mg/L (U.S. Environmental Protections Agency, 2002), and is primarily due to imparting a potential unpleasant taste to the water (Bjorklund and McGreevy, 1971). Plate 1 shows the distribution of total dissolved solids in the Davis County part of the east shore area’s basin-fill aquifer. Based on data from ground-water samples from 123 wells (20 wells sampled by the UGS, 39 public water-supply wells, 64 samples from the USGS), TDS concentrations in the east shore aquifer system in Davis County range from 82 to 1780 mg/L, with only three wells exceeding 1000 mg/L TDS and an overall average TDS concentration of 369 mg/L and median value of 290 mg/L (appendix A, plate 1). Total-Dissolved-Solids Concentrations 19 The ground-water quality (health) standard for nitrate is 10 mg/L (U.S. Environmental Protection Agency, 2002). More than 10 mg/L of nitrate in drinking water can result in a condition known as methoglobinemia, or “blue baby syndrome” in infants under six months (Comley, 1945), which can be life threatening without immediate medical attention (U.S. Environmental Protection Agency, 2010). This condition is characterized by a reduced ability for blood to carry oxygen. Based on data from ground-water samples from 107 wells in the aquifer, nitrate-as-nitrogen concentrations range from less than 0.02 to 8.2 mg/L (appendix A). A majority of wells (56%) had concentrations of less than 1 mg/L, only two wells had nitrate concentration exceeding 5 mg/L and no wells exceeding the EPA standard. Based on the data presented in appendix A, three wells exceeded the EPA primary water- quality standard of 10 μg/L for arsenic. Small amounts of arsenic can cause skin damage or circulatory system problems, and may increase the risk of cancer (U.S. Environmental Protection Agency, 2010). Water samples from three wells exceed the alpha gross 15 pCi/L standard. No other wells exceeded primary ground-water quality standards for any constituent; 20 wells exceeded the secondary standard for iron (300 μg/L) (appendix A). Nitrate Concentrations Other Constituents 20 PROPOSED CLASSIFICATION Under “Administrative Rules for Ground Water Quality Protection R317-6, March 3, 2003,” Section 317-6-3, Ground Water Classes, Utah Administrative Code, Utah’s ground-water quality classes are based on TDS concentrations as shown in table 1. Two other classes, IB and IC, are not based on ground-water chemistry. Class IB ground water, called Irreplaceable ground water, is a source of water for a community public drinking-water system for which no reliable supply of comparable quality and quantity is available because of economic or institutional constraints; this class has not been considered as part of this petition. Class IC ground water, called Ecologically Important ground water, is a source of ground-water discharge important to the continued existence of wildlife habitat. Ground-water protection levels for classes IA and IB, as set under “Administrative Rules for Ground Water Quality Protection R317-6, March 3, 2003,” Section 317-6-4, Ground Water Class Protection Levels, Utah Administrative Code, are more stringent than for other ground-water quality classes. Davis County is petitioning the Utah Water Quality Board to classify the principal basin- fill aquifer of the east shore aquifer system of Davis County as shown on plate 2. The classification is based on ground-water data from the 123 wells presented in appendix A. Where insufficient data exists, extrapolation of ground-water quality conditions is required. We based the extrapolation on local geologic characteristics. The classes (plate 2) are described below. Wells having elevated arsenic concentrations are not mapped as extensive contaminant plumes, and are dominantly isolated wells that are typically adjacent to water wells having low levels of these concentrations; we do not classify single wells, only areas of extensive contamination are considered as Class III. 21 Table 1. Ground-water quality classes under the Utah Water Quality Board’s total-dissolved- solids- (TDS) based classification system (modified from Utah Division of Water Quality, 1998). Ground-Water Quality Class TDS Concentration Beneficial Use Class IA/IB1/IC2 Less than 500 mg/L3 Pristine/Irreplaceable/ Ecologically Important Class II 500 to less than 3000 mg/L Drinking Water4 Class III 3,000 to less than 10,000 mg/L Limited Use5 Class IV 10,000 mg/L and greater Saline6 1Irreplaceable ground water (Class IB) is a source of water for a community public drinking-water system for which no other reliable supply of comparable quality and quantity is available due to economic or institutional constraints; it is a ground-water quality class that is not based on TDS. 2Ecologically Important ground water (Class IC) is a source of ground-water discharge important to the continued existence of wildlife habitat; it is a ground-water quality class that is not based on TDS. 3For concentrations less than 7000 mg/L, mg/L is about equal to parts per million (ppm). 4Water having TDS concentrations in the upper range of this class must generally undergo some treatment before being used as drinking water. 5Generally used for industrial purposes. 6May have economic value as brine. Class IA- Pristine ground water: For this class, total-dissolved-solids concentrations in the Davis County part of the east shore aquifer system range from 86 to 488 mg/L (appendix A). Class IA areas are throughout most of the Davis County part of the east shore aquifer system (plate 2). Areas having Pristine water quality cover about 85% of the total basin-fill material. Class II- Drinking Water Quality ground water: For this class, TDS concentrations in the Davis County part of the east shore aquifer system range from 520 to 1780 mg/L (appendix A). Total basin-fill area coverage of Class II water quality is 15% (plate 2). Class II ground-water quality is dominantly found in the southeastern part of the study area (plate 2). 22 CURRENT BENEFICIAL USES In Davis County, ground water from the basin-fill aquifer is an important source of domestic and municipal culinary water for people living within the valley; surface water, including drains, is an important source of water (Handy and others, 2009). Most water use for all of Davis County as summarized by 2008 municipal water users for Davis County is from drains (35%), followed by wells (25%), streams (23%), and other (17%) (Handy and others, 2009). Total estimated well water withdrawal in 2008 for Davis County was 26,201 acre-feet. Domestic use for 2008 was approximately 40%, wholesale use was 37.5%, commercial use was 10%, industrial use was 5.5%, irrigation and stock water use was about 4%, and other use was about 1% (Handy and others, 2009). WATER-SUPPLY WELLS There are 2785 approved perfected water wells in the Davis County part of the east shore aquifer system based on Utah Division of Water Rights records, 134 of which are public-supply wells (Mark Jensen, Division of Drinking Water, personal communication, August 2010). The locations of all wells are on plate 2. POTENTIAL CONTAMINANT SOURCES We mapped 1798 potential contaminants in the Davis County part of the east shore aquifer system which include some facilities related to mining, agricultural practices, industrial uses, fuel storage, and junkyard/salvage areas (appendix B, plate 3). We located 997 of the 1798 23 potential contaminants from field observations via a windshield survey. We compiled an additional 801 potential ground-water contaminant sources using information obtained from the U.S. Environmental Protection Agency (U.S. EPA), the Utah Department of Environmental Quality (DEQ), the Davis County Health Department and the Utah Automated Geographic Reference Center (AGRC) (2010). The DEQ provided, toxic release inventory (TRI), Tier II, and water-related land-use data. The U.S. EPA provided underground storage tank (UST and LUST) data. The AGRC provided locations for cemeteries, parks, mines, and health care facilities. A primary objective was to identify potential contaminant sources to establish a relationship between water quality and land-use practices. We mapped contaminants in the following categories based on pollutants described the Utah Division of Drinking Water: (1) Mining, which includes abandoned and active gravel, phosphate, and carbonate mining operations. (2) Agricultural practices, which consist of irrigated and non-irrigated farms, animal feeding operations, and cropland; active and abandoned animal feed lots, corrals, stables/barnyards; and animal wastes that are dominantly produced from feeding facilities, waste transported by runoff, and excrement on grazing or pasture land that potentially contribute nitrate. (3) Junkyard/salvage areas that potentially contribute metals, solvents, and petroleum products. 24 (4) Government facility/equipment storage associated with a variety of sources such as salt storage facilities, and transportation/equipment storage that may contribute metals, solvents, and petroleum. (5) Cemeteries, nurseries, greenhouses, ball parks, and golf courses that may contribute chemical preservatives, fertilizer, and pesticides. (6) Storage tanks that may contribute pollutants such as fuel and oil. (7) Equipment vehicle storage and maintenance that may contribute pollutants such as fuel and oil. (8) Manufacturing and industrial uses that may contribute pollutants such as fuel and oil. (9) Rural and residential homes that may contribute pollutants from septic tanks, fuel, household hazardous waste, equipment, and animal by-products. (10) Remediation efforts that may contribute pollutants associated with hazardous material contamination remediation. (11) Wastewater treatment plants and sewage lagoons which may contribute pollutants such as nitrates, fuel, and oil. 25 In addition to the above-described potential contaminants, septic tank soil-absorption systems in the Davis County part of the lower Weber Sub-basin are common and may potentially pollute ground water. There are approximately 257 private septic systems in the Davis County part of the lower Weber Sub-basin (Davis County Health Department, written communication, August 24, 2010). Septic-tank systems may contribute contaminants such as nitrate and solvents. All approved water wells, shown on plate 2, are also considered potential contaminant sources. EXISTING POLLUTION SOURCES Existing pollution sources include those contaminants that have been documented and/or are currently being treated; potential contaminants address pollutants that have the potential to deteriorate ground water. There are known existing sources of pollution in the Davis County part of the east shore aquifer system. Concentrations of organic solvents, such as toluene and trichloroethane, exceeding ground-water quality standards (U.S. Environmental Protection Agency, 2010) have been identified in the shallow unconfined aquifer in the Hill Air Force Base area south of Riverdale and are currently being remediated (Dalpias and others, 1989). Smaller plumes may also be present at other sites in the area, such as the Ogden Defense Depot west of Ogden. GROUND-WATER FLOW Ground-water flow is from the Wasatch Mountains on the eastern margin toward the basin center and Great Salt Lake (plate 2) (from Clark and others, 1990). 26 SUMMARY Ground water is an important source of drinking water in the Davis County part of the east shore aquifer system. Ground-water quality classification is a tool that can be used in Utah to manage potential ground-water contamination sources and protect the quality of ground-water resources. The results of the proposed ground-water quality classification for the Davis County part of the east shore aquifer system indicate that the basin-fill aquifer contains mostly high- quality ground-water resources that warrant protection. Eighty-five percent of the basin-fill area in the Davis County part of the east shore aquifer system is classified as having Class IA ground water, and 15% is classified as having Class II ground water, based on chemical analyses of water from 20 wells sampled during 2010 by the UGS, 39 wells sampled from 1991 to 2009 for data from the Utah Division of Drinking Water, and 64 samples collected by the U.S. Geological Survey from 1960 to 2010.
