GROUND-WATER RESOURCES DATA FOR BALDWIN COUNTY, ALABAMA

By James L. Robinson, Richard S. Moreland, and Amy E. Clark

ABSTRACT

Geologic and hydrologic data for 237 wells were collected, and water-levels in 223 wells in Baldwin and Escambia Counties were measured. Long-term water-level data, available for many wells, indicate that ground-water levels in most of Baldwin County show no significant trends for the period of record. However, ground-water levels have declined in the general vicinity of Spanish Fort and Daphne, and ground-water levels in the Gulf Shores and Orange Beach areas are less than 5 feet above sea level in places.

The quality of ground water generally is good, but problems with iron, sulfur, turbidity, and color occur. The water from most private wells in Baldwin County is used without treatment or filtration. Alabama public-health law requires that water from public-supply wells be chlorinated. Beyond that, the most common treatment of ground water by public-water suppliers in Baldwin County consists of pH adjustment, iron removal, and aeration.

The transmissivity of the Miocene-Pliocene aquifer was determined at 10 locations in Baldwin County. Estimates of transmissivity ranged from 700 to 5,400 feet squared per day. In general, aquifer transmissivity was greatest in the southeastern part of the county, and least in the

o

western part of the county near Mobile Bay. A storage coefficient of 1.5 x 10 was determined for the Miocene-Pliocene aquifer near Loxley.

INTRODUCTIONBaldwin County is the largest county in the State of Alabama. The population of Baldwin

County in June 1994, was estimated at 115,685 (U.S. Bureau of Census, 1995) and is projected to be 150,000 by the year 2000. Currently, Baldwin County is the fastest growing county in Alabama. Major population centers in Baldwin County (fig. 1) are Bay Minette, Daphne, Fairhope, Foley, Gulf Shores, Loxley, Orange Beach, Perdido, Robertsdale, Spanish Fort, and Summerdale.

Baldwin County is 100 percent dependent on ground water for water supply. Ground- water withdrawals in Baldwin County were estimated to be about 7 million gallons per day (Mgal/d) in 1966 (Reed and McCain, 1971), 12 Mgal/d in 1980 (Baker and others, 1982), and 30 Mgal/d in 1990 (Baker and Mooty, 1993). The effects of future increases in ground-water withdrawals, to supply the needs of the growing county population, cannot be assessed without defining existing conditions. To address the future of ground-water development, the Baldwin County Commission requested the U.S. Geological Survey to perform a study of the ground- water resources of Baldwin County.

Purpose and Scope

The objectives of this report are to present a summary of existing ground-water data in Baldwin County, and to present data collected during the period of investigation from September 1994 to November 1995. A literature search for existing data was performed. Geologic and hydrologic data were collected from the files of the U.S. Geological Survey (USGS), Geological Survey of Alabama (GS A), Alabama Department of Environmental Management (ADEM), Alabama Department of Economic and Community Affairs (ADECA), Alabama Department of Transportation (DOT), the Northwest Florida Water Management District (NWFWMD), and from drilling companies in Baldwin County and adjacent counties. To assess current conditions, an inventory of existing wells in Baldwin County was performed; and two synoptic, mass water- level measurements were made in the inventoried wells. The second of these synoptic measurements will be summarized and published later by the USGS. Selected physical and chemical properties of water from wells in Baldwin County are presented. Aquifer-test results were analyzed for 10 public-supply wells.

Previous Investigations

Many reports describe the geology and hydrology of Baldwin County. Adams and others (1926) and Osborne and others (1989) include geologic maps of Alabama. Reed (1971) presents a study of the geology of Baldwin County. Copeland (1968), Miller (1986, 1990), Miller and Renken (1988), and Davis (1987) present regional studies of the geologic and hydrogeologic framework of Alabama and adjacent States. The subsurface geology of Baldwin County was described by Walter and Kidd (1979), Raymond (1983, 1985), Raymond and others (1993), and Smith (1989). Studies of the deep subsurface of Baldwin County include a magnetic survey (Eby and Nicar, 1936) and a gravity map (MeWilliams and Joiner, 1970). Studies of the geomorphology of Baldwin County were included in Carlston (1950), Hardin and others (1976), and Smith (1986). Studies pertaining to the ground-water resources of Baldwin County include Reed and McCain (1971), Walter and Kidd (1979), Hinkle (1984), Chandler and others (1985), Gillett and Moore (1987), Mooty (1988), and Chandler and others (1996).

Acknowledgments

The authors wish to thank the citizens of Baldwin County who assisted the data collection efforts. The staff of the water departments at the cities of Gulf Shores, Fairhope, Bay Minette, Foley, Daphne, Robertsdale, Loxley, Summerdale, Silverhill, and Stapleton deserve special recognition and appreciation for their willingness to adjust pumping schedules so that water-level measurements could be made. The Perdido Bay, Bay Sewer and Water, Orange Beach, Stockton, Tensaw, and Spanish Fort water supply authorities deserve equal recognition. Finally, J.C. Peevy, George Kaiser, Norman and Larry Woerner, Mickey Alms, Sparky Wilson, and Jim Cherry are recognized for their help.

PHYSICAL SETTING OF BALDWIN COUNTYBaldwin County lies within the East Gulf Coastal Plain physiographic section (fig. 2). The

majority of the land area of Baldwin County lies within the Southern Pine Hills District (Sapp and Emplaincourt, 1975). The land area bordering the Alabama and Tensaw Rivers falls within the Alluvial-Deltaic Plain District, and the coastal area of Baldwin County falls within the Coastal Lowlands District.

Land surface elevation in the Southern Pine Hills District ranges from about 300 feet (ft) above sea level to about 30 ft above sea level. The Southern Pine Hills is an elevated, south ward-sloping dissected plain developed on Miocene estuarine deposits to the north and on sand and gravel deposits of the Pliocene Citronelle Formation to the south (Davis, 1987). The Alluvial-Deltaic Plain District consists of alluvial and terrace river deposits. Land surface ranges in altitude from about 100 ft to sea level. The Coastal Lowlands District includes all the coastal areas of Baldwin County up to the base of the Pamlico marine scarp at an altitude of about 25 to 30 ft (Mooty, 1988). Typical landforms in the Coastal Lowlands District include flat to gently rolling plains, tidal streams, marshes, and wetlands.

The terrain in the northern two-thirds of Baldwin County is marked by long, rolling hills, entrenched streams and rivers with steep banks. Streams draining westward to the Alabama and Tensaw Rivers drop to base level in relatively short distances, and are characterized by as much as 250 ft of relief (Davis, 1987). Relief in the southern third of Baldwin County is comparatively small; most streams and rivers have broad channels and low, gently sloping banks.

Climate

Rain is the primary source of ground water, therefore, the average-annual rainfall in Baldwin County is of use in any compilation of ground-water data for Baldwin County. Average-annual rainfall is about 66 inches (in.) with July and August the wettest months and October and November the driest months. Monthly-mean and annual-mean rainfall and temperature data for three stations in Baldwin County, based on the standard 30-year reference period of 1961-90, are listed in table 1 (National Oceanic and Atmospheric Administration, 1991). The data show that the annual-mean rainfall reported at the stations is approximately uniform throughout Baldwin County, with a range from 65.10 to 66.39 in. The difference in monthly-mean rainfall between the wettest months and the driest months is about 4 in. Based on the data in table 1, the coldest month in Baldwin County is January, and the warmest month is July. Average-monthly temperatures range from about 49 to 81 degrees (°F), and the average-annual temperature is about 66 °F.

Rainfall during the 1994 calendar year was unusual because it was unequally distributed and well below average at two of the three stations. Rainfall at Bay Minette was 13.24 in. below average, and rainfall at Fairhope was 4.97 in. below average. Rainfall at Robertsdale was 1.24 in. above aver­ age. Temperatures during the 1994 calendar year were below normal during January, above normal from February to April, below normal from May to September, and above normal for November and December. For the calendar year as a whole, temperatures were 0.7 degrees below normal for Bay Minette, 1.1 degrees below normal at Robertsdale, and 0.8 degrees above normal at Fairhope.

Rainfall during the 1995 calendar year was well above normal due to rain associated with hur­ ricane Erin on August 3 and hurricane Opal on October 4. Rainfall at Fairhope totaled 85.51 in. or 19.11 in. over normal. Temperatures extremes at Fairhope were a high of 99 °F, and a low of 23 °F, with an average of 67 °F; 1 degree above normal for the year. Weather data for calendar year 1995 for Bay Minette and Robertsdale were not available.

Surface-Water Drainage

The major surface-water drainages of Baldwin County are the Alabama, Tensaw, and Perdido Rivers (fig. 1). North of Bay Minette, the Little River, and Turkey, Majors, Halls, and Rains Creeks and Martins Branch flow west into the Tensaw or Alabama Rivers. South of Bay Minette a surface-water divide runs approximately down the center of the county. West of the divide, Bay Minette Creek, the Fish, Magnolia, and Bon Secour Rivers, and the tributaries Cowpen and Polecat Creeks flow into the Tensaw River or Mobile Bay. East of the divide the Styx and Blackwater Rivers, and Dyas and Hollinger Creeks flow into the Perdido River (fig. 1). The extreme southeastern section of Baldwin County is drained by localized creeks into Wolf Bay, Perdido Bay, or the Gulf of Mexico. The largest of these are Miflin, Wolf, and Sandy Creeks.

GEOLOGIC SETTINGThe geologic formations of the Alabama Coastal Plain form a wedge of seaward

thickening sedimentary deposits ranging in age from Late Cretaceous to Holocene. The sediments consist mainly of sand, gravel, silt, chalk, limestone, and sandstone (Davis, 1987). The freshwater-bearing sediments of Baldwin County, to a depth of about 800 ft (fig. 3), are composed of interbedded gravel, sand, silt, and clay of middle Miocene to Holocene age (Reed, 1971; Chandler and others, 1985; Raymond and others, 1993). The sand and gravel units compose the Miocene-Pliocene aquifer system. These aquifers generally are confined to semiconfined by the interbedded clay units (Chandler and others, 1985).

Most of the geologic structures in the subsurface of the Coastal Plain of Alabama (fig. 4) can be attributed to the movement of the underlying Louann Salt of Jurassic age (Davis, 1987). Vertical displacement along the Pollard fault in northeastern Baldwin County should be similar to displacements reported by Cagle and Newton (1963) in Escambia County; 300 ft for beds of Late Cretaceous age and 50 ft for beds of Eocene age. The Wiggins Uplift in Baldwin County is probably related to a deep salt core (MeWilliams and Joiner, 1970), and gravity anomalies to the north and southwest of Tensaw are interpreted as faults associated with the Mobile Graben. Effects of the deep structures generally are masked by thick overlying sediments (MeWilliams and Joiner, 1970).

The dip of shallow sediments in southern Baldwin County is assumed to follow the surface of the Pensacola Clay (Walter and Kidd, 1979). The Pensacola Clay, a marine clay of middle Miocene age, is estimated to dip south 28 degrees west at a rate of 38 feet per mile (ft/mi). The Pensacola Clay is absent in northern Baldwin County, and no marker bed which could be used to determine a regional structural trend has been identified in the shallow subsurface; but the top of the Claiborne Group of Eocene age is reported by Davis (1987) to have a regional dip of about 50 ft/mi to the south-south west. Me Williams and Joiner (1970) also report a regional dip for Baldwin County of 5 to 50 ft/mi to the south-southwest.

Recent studies by the Geological Survey of Alabama (Raymond, 1985; Smith, 1989, 1991; Raymond and others, 1993) have presented the results of detailed studies of the Miocene and post-Miocene subsurface stratigraphy in southern Baldwin County. Formally, sediments overlying the Pensacola Clay, excepting maximum thicknesses of 50 to 100 ft for the Citronelle Formation and recent river terrace and floodplain deposits, were classified as Miocene undifferentiated. Up to 500 ft of Pliocene age sediments are now mapped in the subsurface of southern Baldwin County by the Geological Survey of Alabama based on biostratigraphic studies (Raymond and others, 1993). Similar studies have not been made in northern Baldwin County.

GROUND-WATER RESOURCES DATAWell Inventory

A county-wide well inventory was performed to identify wells suitable for measuring ground-water levels. The objective of this work was to lay the groundwork for constructing a water-level map for the Miocene-Pliocene aquifer system in Baldwin County. Data for 237 wells are included in this report. Water-level measurements were made in 223 of these wells, and historic water-level data are available for many of the wells. Driller's logs, geologic logs, geophysical logs, aquifer-test or well-performance data, and water-quality data were also collected when possible.

Well Numbering System

The well-numbering system used in this report is based on the Federal system of subdivision of public lands. Each township is divided into 36 sections numbered from 1 in the northeast corner to 36 in the southeast corner. Each township is assigned a letter in the same order that sections are numbered from "A" through "Z," with "A" being assigned to the northeastern- most equal township and "Z" to the southeasternmost township. Letter designations are doubled or tripled as needed. Wells in each subdivision are numbered consecutively such as K-5.....K-9 (fig. 5) in the order that the wells are inventoried. Other numbering systems have been used in previous studies of Baldwin County. For this reason, many wells inventoried in this report have other number designations, in most cases assigned by the Geological Survey of Alabama.

Well-Site Data

Basic data for all wells used in this study are listed in Appendix 1 by well number. Included in Appendix 1 are data describing owner, location, construction, altitude of land surface, water-level measurements, date of measurement, and use of the water. Well location and land- surface altitude were determined by site visit and locating the well on both USGS 7 1/2-minute quadrangle maps (1 in. = 24,000 in.) and county road maps of various scales. Site locations generally are considered accurate to within about 100 ft. The accuracy of the land-surface altitude is dependent on the contour interval of the USGS 7 1/2-minute map and the accuracy of the estimated location. Land-surface altitude is considered accurate to within plus or minus 2.5 ft for most wells, and to within 5 ft for all wells. Land-surface altitude for seven wells was determined either by previous studies or during this study by standard survey leveling. The locations of selected inventoried wells are shown on figure 6.

Ground-Water Use

The Miocene-Pliocene aquifer system is currently the sole source of public-water supply in Baldwin County. It is also heavily utilized for self-supplied domestic, agricultural, and recreational purposes. The aquifer system can yield up to 1 Mgal/d to properly constructed wells. Wells supplying private homes rarely need be more than 200 ft deep, with the most common depth being about 100 ft. Public-supply wells generally are between 100 and 300 ft deep.

The estimated average daily ground-water use by category in Baldwin County in 1995 was based on most recent (1990) tabulations of water use in Alabama (Baker and Mooty, 1993) and the Alabama Department of Economic and Community Affairs (ADECA) water-use reporting program that began in 1993. The ADECA program requires reporting for all uses over 100,000 gallons per day (gal/d). Ground-water use data for Baldwin County from Baker and Mooty (1993) and the ADECA water-use reporting program are summarized in table 2. Total estimated ground-water use in Baldwin County is about 41 Mgal/d. Agricultural use accounts for about 68 percent, public water supply accounts for about 30 percent, and the other 2 percent is for self-supplied domestic, commercial, and industrial uses. Major centers of ground-water withdrawal in Baldwin County are shown on figure 7.

Ground-Water Levels

Water-level measurements were made in 223 of the 237 wells inventoried for this study. These data were summarized in the form of a map of the potentiometric surface of the Miocene- Pliocene aquifer system (Robinson and others, 1996). Ground-water levels ranged from a high of 259 ft above sea level near the Baldwin County/Escambia County border to about sea level at some locations near the Gulf Coast. A ground water high is oriented roughly north-south along a line that extends from the Baldwin County/Escambia County border to about 10 miles south of Bay Minette. A pronounced area of low ground-water levels occurs in the Spanish Fort Area. Ground-water levels along the entire Gulf Coast of Baldwin County were less than 5 ft above sea level during October and November 1995.

At many locations, multiple wells completed at different depths were measured. These data provided information about vertical ground-water gradients within the ground-water system (fig. 8). In general, ground-water levels decreased with depth in most areas of Baldwin County. This indicates a potential for aquifer recharge in these areas. Near the Gulf Coast, major rivers, and Mobile Bay, ground-water levels increase with well depth indicating discharge areas for the ground-water system. Table 3 presents water-level data for selected well clusters in Baldwin County, and figure 8 shows the locations of those well clusters.

In November 1994, a continuous water-level recorder was installed in well ZZ-10, an inactive well of the city of Gulf Shores. The mean daily water-level in well ZZ-10 (fig. 9) shows the effects of ground-water withdrawals and seasonal rainfall patterns. Short term water-level fluctuations probably represent the effects of nearby pumping from the aquifer for agricultural irrigation. Long term trends result from the effects of seasonal rainfall. In general, water levels in well ZZ-10 declined from late spring to late summer, and rose from late summer until mid-spring. The lowest water levels occurred during the tourist season, when pumping for public supply was greatest

Historic ground-water level data were collected from the files of the Geological Survey of Alabama, USGS, and from the public-water suppliers in Baldwin County. These data are presented in table 4. No significant long-term trends were indicated by the historic water-level data, except for the Spanish Fort and Daphne areas where a water-level decline of 35 ft from 1966 to 1991 was observed in the Miocene-Pliocene aquifer system (fig. 10). Water-level measurements in well LL-6 (fig. 10) in 1992 and 1994 suggest that water levels in the Miocene- Pliocene aquifer may be recovering.

Ground-Water Quality

The quality of the water in the Miocene-Pliocene aquifer system generally is good, and many self-supplied homeowners use ground water with no treatment. Water-quality data for all of Baldwin County were published by Reed and McCain (1971); Walter and Kidd (1979) and Chandler and others (1985) published water-quality data for southern Baldwin County.

In general, ground water is more acidic in the southern part of the county. Ground water with dissolved-solids content exceeding 1,000 milligrams per liter (mg/L), a chloride content of 500 mg/L, and having a sulfurous odor occurs in the areas adjacent to the Mobile River and locally near the Gulf of Mexico. Ground-water quality in the inland areas is acidic and low in mineral content. In coastal areas, hydrogen sulfide and methane may occur. Problems with iron and sulfur occur in the Spanish Fort and Orange Beach areas.The results of chemical analyses of water from selected wells in Baldwin County are presented in table 5. The well locations are shown on figure 11.

Aquifer Test Results

Prior estimates of the hydraulic characteristics of the Miocene-Pliocene aquifer system, reported by Walter and Kidd (1979), give a range of transmissivity from 1,150 to 2,400 feet squared per day (ft2/d) and storage coefficients ranging from 0.00014 to 0.00115. During this study, hydraulic characteristics for the Miocene-Pliocene aquifer system of Baldwin County were estimated at 10 locations using data from 11 wells (table 6). All of the aquifers tested were con­ fined.

All but one of the aquifer tests were single-well tests. In general, only moderate confidence can be placed on the results of a single-well test, and transmissivity is the only hydraulic characteristic that can be estimated. A multi-well aquifer test was performed for the city of Loxley public-supply well number 2 (KK-8) by the Geological Survey of Alabama (Tackle and others, 1993). It was possible to estimate the transmissivity and storage coefficient of the aquifer at this location.

/^

Estimates of aquifer transmissivity in Baldwin County ranged from 700 to 5,400 ft/d. Transmissivities were greatest in the southeastern part of the county, and least in the western part of the county near Mobile Bay (fig. 12). A storage coefficient of 0.0015 was determined for the Miocene-Pliocene aquifer near Loxley.

SUMMARYBaldwin County lies within the East Gulf Coastal Plain physiographic section. The major

surface-water drainages are the Alabama, Tensaw, and Perdido Rivers. The freshwater-bearing sediments are composed of interbedded gravel, sand, silt and clay. These aquifers generally are confined to semiconfined by the interbedded clay units.

The Miocene-Pliocene aquifer system is currently the sole source of public-water supply in Baldwin County. It is also heavily utilized for self-supplied domestic, agricultural, and recreational purposes. Wells supplying private homes rarely need be more than 200 feet deep, with the most common depth being about 100 feet. The depth of public-supply wells generally ranges between 100 and 300 feet.

The ground-water resources data presented in this report represent conditions for the Miocene-Pliocene aquifer system for the period of September 1994 to November 1995. Total daily withdrawal from the Miocene-Pliocene aquifer system was estimated to be 41 million gallons per day. Agricultural use accounts for about 68 percent, public water supply accounts for about 30 percent, and the other 2 percent is for self-supplied domestic, commercial, and industrial uses.

Comparison of historic and current ground-water level data indicate that there has been no significant decline in ground-water levels in most of Baldwin County. This suggests that current ground-water use levels in Baldwin County are sustainable. However, ground-water levels may be declining in the general area of Spanish Fort and Daphne. Ground-water levels in the Gulf Shores and Orange Beach areas are less than 5 feet above sea level in places.

Water quality generally is good, and many self-supplied homeowners use ground water with no treatment. Problems with water quality occur near the Mobile River, Spanish Fort, and Orange Beach areas.

The transmissivity of the Miocene-Pliocene aquifer system of Baldwin County, estimated at 10 locations using pump test data from 11 wells, ranged from 700 to 5,400 feet squared per day. Transmissivities were greatest in the southeastern part of the county, and least in the western part of the county near Mobile Bay.
