WATER LEVELS IN ARTESIAN AND NONARTESIAN
AQUIFERS OF FLORIDA, 1963-64

By

INTRODUCTION

This report summarizes the trends and fluctuations of ground-
water levels in the principal aquifers in Florida during 1963-64 and
includes the following: (1) hydrographs of ground-water levels in
the several aquifers; (2) maps showing changes in ground-water
levels during specific periods; and, (3) a table summarizing the
principal data on selected observation wells. Observation wells
for which records are available are listed in the "Index to Water
Resources Data-Collection Stations in Florida, 1961", Florida
Geological Survey Special Publication No. 11, which includes
the location, aquifer, and type and period of records available for
about 3,600 observation wells.
Since World War II, and particularly during the last decade,
the demand for fresh water for industrial, municipal, and agricul-
tural use in Florida has increased yearly. Although ground-water
supplies have been adequate for the increased demand in most
areas in Florida, water levels have declined appreciably in some
areas. Because demand for ground water continues to increase,
shortages will occur and may become critical in some areas. In
coastal areas, declining water levels may allow salt water to
encroach and shortages could result from deterioration in quality
as well as from the reduction of quantity of water available. In
order to prevent future shortages, the supplies of ground water
must be properly appraised before they can be effectively utilized.
Records of trends and fluctuations of ground-water levels have
long formed a basis for such an appraisal.
The principal objective of the Water Resources Division of
the U.S. Geological Survey is to appraise and to evaluate the
Nation's water resources. Although many types of ground-water
investigations are conducted throughout the Nation, the collection
and compilation of basic hydrologic data constitute an important
part of the water-resources studies.
Objectives of the hydrologic data program include: the eva-
luation of available ground-water supplies; the prediction of trends

of water levels; and the delineation of present or potential areas
of detrimentally high or low ground-water levels. Water levels are
also used to predict the base flow of streams, to portray the effects
of natural and man-induced forces that act on a water-bearing
formation, and to furnish information for use in research. The
hydrologic data program is an important adjunct of the several
types of geologic and hydrologic methods of study used in water-
resources investigations.
The hydrologic data-collection program of the U. S., Geol-
ogical Survey is part of the cooperative investigations of the
ground-water resources of Florida, in cooperation with the Div-
ision of Geology, Florida Board of Conservation, and other state
and local agencies and municipalities. The observation-well
network in 1964 included about 1,000 observation wells in the
67 counties of the State. Figure 1 shows the locations of these
observation wells and Table 1 lists data for 329 observation wells
selected from the statewide network.
The hydrologic-data program consists of the collection, tab-
ulation, interpretation, evaluation, and publication of water-level
and related data. Water levels for selected wells are published,
at present, once every 5 years in the U. S. Geological Survey
Water-Supply Papers.
Information pertinent to ground water is also published in
interpretative reports of investigations published by the Florida
Geological Survey and the U. S. Geological Survey. Data collected
during an investigation and subsequent to publication are available
from the District Chief, U. S. Geological Survey, P. O. Box 2315,
Tallahassee, Florida 32304.
The water-level data used in this report represent measure-
ments taken from automatic water-stage recorder charts, pressure
gages, and made by wet tape. In general, water-level measurements
made by tape and stage recorder are shown to the nearest hundredth
of a foot, and those made with a pressure gage are shown to the
nearest tenth of a foot.
Table 1 summarizes well-data and water-level information for
the several aquifers. Well data include the aquifer, depth of well,
and depth of casing. The items: "Year record began" and "Fre-
quency of measurements" are included as part of the well data.
In the water-level portion of the table, levels for May or June are
used because records are available for these months for a large
percentage of the wells. Also, ground-water levels generally are
lowest during May or June in many areas and records during that

Table l.--Summary of well data and water levels in selected-observation vells.

Well number: Well numbers are based on county numbering system e.g. Bay County well Bay 20, or on the lati-
tudinal and longitudinal system e.g. well 008-537-2. Both numbers 20 and 008-537-2 are given where this
well has been reported previously in a publication under the county number. Letters prefixed to well
numbers in Broward and Dade Counties; G, Geological Survey wells,; S, supply wells; F, fire wells; and
NP. National Park Service wells. Letter suffix A, shallow well adjacent to deep well.
Aquifer: B, Biscayna; F, Floridan; G, sand-and-gravel; H, Hawthorn; NA, nonartesian; S, shallow sand.
Depth of well: Measured unless otherwise noted. R, reported depth.
Frequency of measurement: Refers to current biennium. B, bimonthly; C, continuous; M, monthly; S, semi-
annually; W, weekly.
Prior to 1963: When only one measurement is available prior to current biennium, measurement is arbitrarily
Listed as a low level.
Water level: To hundredth of a foot if measured by vet-tape method or taken from recorder chart; to nearest
tenth of a foot if measured by pressure gage or airline.
Annual range: Based on measurements available during year. For wells equipped with recorder, range is
based on every 5th day measurements.
Remarks: B, water level below measuring point; D, measurements discontinued on date shown in Remarks;
L. lowest water level; M, water level with reference to mean sea level; P, water level affected by
pumping of nearby wells; R, recorder installed on date shown in Remarks; S, water level affected by
seasonal or regional pumping; T, water levels affected by ocean tides.

WELL-NUMBERING SYSTEM

Two well-numbering systems are used in this report. 'Obser-
vation wells in Florida are numbered serially by counties and/or by
a grid-coordinate system on latitude and longitude of the well
location. Frequently, both numbers are assigned to a well e.g. a
well number may be shown as 20(008-537-2). This affords a tie-in
with water-level data published previously under well number 20
in Bay County with data that may be published for the same well
under number 008-537-2.
Some wells used in table 1 have numbers with a letter prefix
or suffix. In Broward and Dade counties, the letter prefixes G, S,
F, and NP denote Geological Survey wells, supply wells, fire
wells, and National Park Service wells, respectively. In Dade,
Escambia, Highlands, Holmes, and Leon counties, the letter
suffix A denotes a shallow well near a deeper well having the
corresponding number without the letter suffix. In Orange County,
the letter suffixes B and C denote shallow wells drilled in the
vicinity of well 47.
The grid-coordinate well-numbering system in Florida is
derived from latitude and longitude coordinates. The latitude and
longitude prefix north and west and the first digit of the degree
number are not included in the well number.
The well number is a composite of three numbers separated
by hyphens: the first number is composed of the last digit of the
degree and the two digits of the minute that define the latitude on
the south side of the 1-minute quadrangle; the second number is
composed of the last digit of the degree and two digits of the min-
utes that define the longitude on the east side of a 1-minute quad-
rangle; and, the third number gives the numerical order in which
the well was inventoried in the 1-minute quadrangle. For example,
well number 835-105-1 is the first well inventoried in the 1-minute
quadrangle north of the 28035' parallel of latitude and west of the
81005' meridian of longitude. The location of well 835-105-1 is
shown diagrammatically in figure 2.

PRINCIPAL AQUIFERS

Ground-water supplies for industrial, agricultural, and mun-
icipal use in Florida are available from three principal aquifers:
the Floridan aquifer in central and northern Florida; the Biscayne
aquifer in southeastern Florida; and, the sand-and-gravel aquifer
in the extreme northwestern part of Florida. The generalized
areal extent of the aquifers supplying most of the ground water
is shown in figure 1.
The Floridan ,aquifer, which underlies all of the State, is
the principal source of water in central, northern, and most of
northwestern Florida, as shown on figure 3. Highly mineralized

Figure 3. Map showing piezometric surface and areas of 'flow of the
Floridan Aquifer, in Florida, July 6-17, 1961.

INFORMATION CIRCULAR NO. 52

water precludes the usefulness of the Floridan aquifer as a source
of potable water in some coastal areas and in most of southern
Florida. In those areas, shallow artesian and nonartesian aquifers
are the source of supply.
The Biscayne aquifer in southeastern Florida is the chief
source of water supply for industries, municipalities, and irrig-
ation. This aquifer, one of the most highly productive aquifers in
the world, underlies about 3,500 square miles of Broward, Dade,
and Palm Beach counties. The usefulness of the Biscayne aquifer
is sharply restricted in areas adjacent to the coast because of the
presence of saline waters.
The sand-and-gravel aquifer in extreme northwestern Florida
is the principal source of water supply, yielding large quantities
of water for industries and municipalities. The aquifer underlies
all of Escambia and Santa Rosa counties and part of western
Okaloosa County.
This report of ground-water conditions has been divided into
four geographical areas as follows: (1) northwestern Florida,
(2) northern, northeastern, and north-central Florida; (3) central
Florida; and, (4) southern and southeastern coastal Florida.

NORTHWESTERN FLORIDA

Northwestern Florida as used here includes the Panhandle
region extending from the Apalachicola River westward to the
Florida-Alabama line, figure 4.
The principal sources of ground-water supply in the region
are the sand-and-gravel aquifer in Escambia and Santa Rosa
counties and the Floridan aquifer in the rest of the region. Minor
supplies of ground water are obtained from shallow nonartesian
aquifers.
The Florida Panhandle includes three rapidly growing areas
of industry and population: the Pensacola area, the Ft. Walton
Beach area, the Panama City area.

PENSACOLA AREA

The Pensacola area includes Escambia and Santa Rosa coun-
ties. This area, like many others in the State, is undergoing rapid
economic development. Industrial and municipal water uses are
increasing. Pumpage in the Pensacola area in 1964 was about five
times that in 1940. Figure 5 shows pumpage for the City of Pensa-
cola, 1933-64.

Figure 5. Graph of total yearly pumpage, City of Pensacola.

The observation-well program in the Pensacola area began in
1939 as part of the investigation to determine the adequacy and
permanency of ground-water supply in Escambia County. Figure 4
shows locations of the observation wells selected from the hydro-
logic-data network for which hydrographs are given in this report,
and table 1 presents data on 13 wells in Escambia County and
5 wells in Santa Rosa County. Figure 6 shows fluctuations and
long-term trends of artesian water levels in the sand-and-gravel
aquifer in the Pensacola area from 1940 through 1964.
Comparison of the hydrographs for the period of record reveals
that while water levels at the end of 1964 declined in central
Escambia County, water levels in the southern part of the county
near the coast were above 1940 levels. Declines of artesian
water levels in the sand-and-gravel aquifer ranged from a maximum
of nearly 35 feet in well Escambia 45 at Cantonment to a minimum
of less than 2 feet in well Escambia 46 near Ensley during 1941-
64.
In the coastal area, at Pensacola, the artesian water level
in well Escambia 62, at the end of 1964, was about 2 feet above
the 1942 level. The trends and fluctuations of artesian ground-
water levels in well Escambia 62 and departures from monthly
average rainfall at Pensacola, 1960-64 are shown in figure 7.

counties and the Floridan aquifer in the rest of the region. Minor
supplies of ground water are obtained from shallow nonartesian
aquifers.
The Florida Panhandle includes three rapidly growing areas
of industry and population: the Pensacola area, the Ft. Walton
Beach area, the Panama City area.

PENSACOLA AREA

The Pensacola area includes Escambia and Santa Rosa coun-
ties. This area, like many others in the State, is undergoing rapid
economic development. Industrial and municipal water uses are
increasing. Pumpage in the Pensacola area in 1964 was about five
times that in 1940. Figure 5 shows pumpage for the City of Pensa-
cola, 1933-64.

FT. WALTON AREA

The Ft. Walton area includes the Ft. Walton Beach area and
Eglin Air Force Base at Niceville. The rate of growth of industry
and population is accelerating. Pumpage from the Floridan aquifer
for all uses is about 10.0 mgd (million gallons per day). As a
result of continuing heavy pumping, water levels have declined in
about a 640 square-mile area.
The hydrograph of well Okaloosa 3 at Ft. Walton Beach,
figure 8, shows a maximum decline of 98.3 feet from 18.5 feet
above land surface in 1947 to 79.8 feet below land surface in
1964. In August 1936, the artesian water level was 46 feet above

1964, the water level in well Okaloosa 3 declined 125 feet, from
46 feet above land surface to 79 feet below land surface. The
areal extent of the decline in artesian levels in the vicinity of
Ft. Walton Beach is shown by the net change of water levels
map, figures 9 and 10. Water-level changes during 1951-62 are
shown by figure 9. Changes of groundwater levels for the current
period May 1962-64 are shown by figure 10.

PANAMA CITY AREA

The Panama City area includes 250 square miles in Bay
County, including Tyndall Air Force Base.
The Floridan aquifer supplies most of the water for munici-
pal, industrial, and military needs in the area. Figure 11 shows
total pumpage from the Panama City well fields at St. Andrews
and Millville for the period 1944-64. Pumpage of ground water for
municipal use declined from an average of 1,200 mgy (million
gallons per year) in 1961-62 to an average of 860 mgy in 1963-64.
To some extent, reduced pumpage by Panama City and a change
in locale of source of water by the pulp industry allowed water
levels to rise sharply during 1963-64. Instead of the usual fall
and winter rise of 2 to 7 feet, water levels rose 24 feet from 78
feet to 54 feet below land surface from June 1963 through Dec-
ember 1964. The alteration of the pattern of fluctuations of water
levels was probably also the result of above average annual rain-
fall in the area during 1964.
The long-term trends and fluctuations of ground-water levels
at Panama City are shown by the hydrograph of well Bay 7, figure
12. The decline of water level in well Bay 7 represents the max-
imum known decline in the area and is caused by pumping in near-
by wells. In August 1936, the water level in well Bay 7 was about
36 feet below land surface, while in June 1963, it was about 78
feet below land surface, a maximum decline of 42 feet.

NORTHERN AND NORTH-CENTRAL FLORIDA

Northern and north-central Florida as used in this report
extends from the Apalachicola River eastward to the Atlantic
Ocean and from the Georgia line southward to the latitude of
Ocala, figure 13, and includes 24 counties and parts of Levy

TALLAHASSEE AREA

The Tallahassee area includes central Leon County and the
City of Tallahassee. The area is primarily residential and only
sparse light industry is located in this area.
The principal water user, the City of Tallahassee, supplies
water for municipal use to the most rapidly growing residential
and educational complex in the Big Bend. Since 1945, annual
municipal pumpage at Tallahassee has increased 365 percent
from about 850 mgy to 3,100 mgy. Figure 14 shows pumpage during
1933-64 for the City of Tallahassee.
Fluctuations of water levels in the Floridan aquifer at Tall-
ahassee are shown by the hydrograph, figure 15, of well Leon 7,
which shows a downward trend during 1960-63 and an upward trend
in response to above average rainfall during 1964. The graph
shows characteristic seasonal trends with high levels in the spring
and low levels in the fall. Figure 16 shows water levels in well
Leon T for the period 1945-64.

FERNANDINA-JACKSONVILLE AREA

The Fernandina-Jacksonville area is one of the largest indus-
trialized areas in the State, with water use increasing as a result
of the rapid economic expansion. Figure 17 shows total yearly
municipal pumpage for Jacksonville from 1921-64.
Ground-water levels in the Fernandina-Jacksonville area
have been declining for a considerable period of time. Trends and
seasonal fluctuations of the. water levels in the Floridan aquifer
at Jacksonville are shown for well Duval 122 and for well Duval
164 near Mayport. IHydrographs of wells'in the Floridan. aquifer
in Nassau and Duval counties are shown in figures 16 and 18.
Water levels declined to near record low levels in many wells
in the area during 1963. Maximum decline of water levels occurred
in well Nassau 12 in the Fernandina area. Levels, in this well,
declined 47 feet from 29 feet above to 18 feet below land surface
during 1946-63. The maximum decline was 59 feet for the period
of record 1939-63. In contrast, water levels in well Nassau 51,
approximately 20 miles inland, declined only .about 13 feet during
1945-46. Water levels in well Duval 122 at Jacksonville declined
nearly 22 feet from 1930 to 1964, while along the coastal area in
Duval County water levels generally declined about 18 feet in
well Duval 164. These declines are part of the broad regional

The principal source of ground-water supply in western coas-
tal and central peninsular Florida is the Floridan aquifer. In the
eastern coastal area, the nonartesian shallow-sand aquifer is the
chief source.
Central Florida includes four rapidly growing centers of pop-
ulation and industry: the Tampa-St. Petersburg area, the Lakeland
area, the Orlando-Cape Kennedy area, the Sarasota-Bradenton area.

TAMPA-ST. PETERSBURG AREA

This area, particularly in the vicinity of Tampa and St. Peters-
burg, is undergoing a rapid expansion in both industry and popul-
ation.
The long-term trends and fluctuations of ground-wations of ground-water levels
in the Floridan aquifer in the Tampa-St. Petersburg area are
shown in figure 21. The hydrographs show a similarity of water-
level fluctuations in well Pasco 13 near Ehren and well Hillsbor-
ough 13 near Citrus Park, during the period 1945 through 1962.
Drought conditions and increased pumping during 1961-64 caused
water levels in Hillsborough 13 to decline to the lowest levels of
record in 1964. Rainfall recorded at Tampa and the fluctuations

ty, water levels in well Hillsborough 30 declined to the lowest
level of record in 1963, shown in figure 23. This decline is part
of an extensive regional lowering of water levels which extends
from southern Hillsborough County into Sarasota County. (See
figure on page 54).
Water levels in two Pinellas County wells, Pinellas 13 and

13. However, a slight downward trend from 1946 through 1956 can
be noted for Pinellas 246. This downward trend .was reversed dur-
ing the latter part of 1956 and levels continued to rise through
1959 and were about average for the period of record 1963-64.

figure 28 are the fluctuation of water levels in the artesian aquifer
and in the shallow-sand aquifer caused by the droughts of 1955-56
and 1961-62 and subsequent recovery of levels during post-drought
periods.
In southern Polk County at Frostproof, water levels declined
about 11 feet in the artesian aquifer in well Polk 51 from January
1960 to May 1962. In central Highlands County near Sebring, levels
declined nearly 6 feet in the nonartesian aquifer in well Highlands
10 during the same period. During 1962 ground-water levels rose
sharply. However, in most wells, the recovery of levels in 1963-64
did not exceed those of 1960. Water levels during 1964 ranged from
1.5 feet below 1960 highest levels in the artesian aquifer at Frost-
proof to 5.1 feet lower than 1960 levels in the nonartesian aquifer
in central Highlands County. In southern Osceola and southeastern
Highlands counties, 1963-64 water levels in the nonartesian aquifer
ranged from 1 foot lower in wells Osceola 183 and Okeechobee 3
to 2.4 feet lower than 1960 levels in well Highlands 13. Figure'29

SOUTHERN FLORIDA

The southern Florida region includes all counties south of a
line through Desoto County and covers an area of about 17,500
square miles. The region and the locations of selected observation
wells for which hydrographs are presented are shown on figure 34.
In southern Florida, nonartesian aquifers are the principal
source of water supply. In the coastal areas of Martin and Palm
Beach counties, a nonartesian shallow-sand aquifer is the chief
source of supply; in Broward and Dade counties, the Biscayne
aquifer is the principal source; and in southwestern coastal Flor-
ida and inland areas, nonartesian shallow-sand and shell aquifers
are the main sources.

FT. MYERS AREA

The Ft. Myers area includes Lee and Charlotte counties, and
like the Bradenton-Sarasota area to the north is developing rapidly
as a winter tourist and retirement center.
The principal source of ground water in the Ft. Myers area is
the nonartesian aquifers. Figure 35 shows the seasonal fluctua-
tions of ground-water levels in well Lee 246 and rainfall at Ft.
Myers for the period 1960-64. Generally, seasonal fluctuations of
water levels in nonartesian aquifers closely correspond to seasonal
fluctuations in the amounts of rainfall. Figure 36 shows the trends
and fluctuations of water levels in nonartesian aquifers for selec-
ted wells in southern Florida.

This area includes coastal parts of Martin and Palm Beach
counties and is a segment of the rapidly growing, populous, coastal
complex extending from Jacksonville southward through the Keys.

graph of well Martin 147 shows a downward trend of nonartesian
levels. Levels declined to a record-low level of about 2 feet above
mean sea level in the spring of 1962 and 1963. The declines during
1961-63 were caused, in part, by increased pumping in the Stuart
well field. Although pumpage increased during 1964, water levels
rose in response to above average rainfall. Figure 38 shows trends
of water levels and rainfall recorded at Stuart, 1960-64.

DIVISION OF GEOLOGY

MIAMI AREA

The Miami area includes Broward and Dade counties and is
the most populous area in the State. The principal source of water
supply is the Biscayne aquifer, the extent of which is shown on
figure 1.
The locations of selected observation wells in the Miami
area for which hydrographs are given, are shown by figure 34.
Water-level observations were made as early as -1933 near
Homestead in well Dade S196A. Long-term record of water-level
fluctuations at Homestead are shown in figure 41. Figure 43 shows
trends of water levels and rainfall recorded at Homestead Experi-
mental Station 1960-64.
Except for the relatively narrow coastal strip, most of the
Miami area is occupied by the Everglades. Fluctuations of ground-
water levels in the Everglades are shown by hydrographs of wells
Dade G72, G596, G618, and G620, figures 44 and 45.
Fluctuations of ground-water levels in the Biscayne aquifer
in the vicinity of Miami are illustrated by hydrographs of wells
Dade G10 about 5 miles west of Miami, Dade S19 at Miami Springs
(fig. 44), and well Dade F179 at Miami (fig. 41). The water level
in well Dade S19 is affected by pumping in the municipal well
field of the City of Miami.
In the Miami area, as in other coastal areas, the presence of
salty water in an aquifer is signalled by high chloride content of
the ground water. The seaward reaches of the Biscayne Aquifer
contain sea water and some encroachment of sea water into the
aquifer has occurred through the years. Water control measures
have checked the encroachment and as a result a freshening of
the ground water has occurred in some areas.
Generally, chloride content of ground water decreased in the
Miami area and in southern coastal Dade County during 1963-64.
Figure 42 shows fluctuations of chloride content of ground water
in the Biscayne aquifer in the Miami area. Chloride content of
ground water in well Dade F64 in Miami decreased to the lowest of
record since 1947. During 1963-64, chlorides ranged from 250 to
550 ppm in this well. Chloride content of ground water in the
Biscayne aquifer ranged from 400 to 700 ppm in well F296 on the
coast north of Miami. Chloride content was generally lower during
1963-64 than during 1962. Near the eastern edge of the Miami well
field area in Miami Springs, chloride content decreased from 900

ppm in 1946 to 100 ppm in 1962 in well Dade G354. During 1963-64,
chloride content decreased to the lowest of record in this well.
In southern coastal Dade County, chloride content of ground
water in the Biscayne aquifer generally decreased or remained at
low concentrations in several areas during 1963-64. Chloride
content decreased to less than 500 ppm in well Dade S529 on the
coast and that of well Dade G212 southeast of Homestead remained
at less than 200 ppm during 1963-64. In sharp contrast, the chloride
content in well Dade G469 near the coast south of Miami increased
from about 20 ppm in 1961 to about 8600 ppm in 1964 as a result
of new canal construction in that area.
In the Miami area, as in other coastal areas, the contamination
of the Biscayne aquifer by the encroachment of salty water is an
ever-present problem. Through intensive practice of water control
the problem of prevention of salt-water contamination has been
solved. In many areas where contamination existed the situation

SOUTHERN FLORIDA

The southern Florida region includes all counties south of a
line through Desoto County and covers an area of about 17,500
square miles. The region and the locations of selected observation
wells for which hydrographs are presented are shown on figure 34.
In southern Florida, nonartesian aquifers are the principal
source of water supply. In the coastal areas of Martin and Palm
Beach counties, a nonartesian shallow-sand aquifer is the chief
source of supply; in Broward and Dade counties, the Biscayne
aquifer is the principal source; and in southwestern coastal Flor-
ida and inland areas, nonartesian shallow-sand and shell aquifers
are the main sources.
