WATER LEVELS IN ARTESIAN AND

NONARTESIAN AQUIFERS
OF FLORIDA, 1967-68
By
Henry G. Healy

INTRODUCTION

This report summarizes the trends and fluctuations of ground-
water levels in the principal aquifers in Florida during 1967-68 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. The index, prepared by the U. S.
Geological Survey in cooperation with the Florida Geological Survey,
(now the Bureau of Geology, Florida Division of Natural Resources),
includes the location, aquifer, and type and period of records avail-
able for 3,600 observation wells.
Since World War II, and.particularly during the last decade, the
demand for fresh water for industrial, municipal, and agricultural
uses in Florida has increased yearly. Although ground-water supplies
have been adequate for the increased demand in most areas, water
levels have declined appreciably in some. 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 present
supplies of ground water must be properly appraised before they can
be effectively utilized. Records of trends and fluctuations of ground-
water have long formed a basis for such an appraisal.
The principal objective of the investigations 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 carried out on a statewide basis
throughout the nation, the collection and compilation of basic
hydrologic data constitute an important part of the water resources
studies.

BUREAU OF GEOLOGY

Objectives of the hydrologic data program include: the evalua-
tion 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 used
to determine the base flow of streams, to portray the effects of
natural and man-induced forces that act on a water-bearing forma-
tion and to furnish information 'for use in basic research. The
hydrologic data program provides the foundation information neces-
sary for the successful and meaningful accomplishment of water
resources investigations.
The hydrologic data-collection program of the U. S. Geological
Survey is part of the cooperative investigations of the water resources
of Florida in cooperation with the Division of Geology, Florida
Board of Conservation, and other state and local agencies and
municipalities. The observation-well network in 1968 included about
920 ground-water data-collection stations in the 67 counties of the
state. Figure 1 shows the locations of selected ground-water stations
in the statewide network. Table 1 (see appendix) lists data on 348
observation wells selected from the statewide network of wells.
The hydrologic-data program consists of the collection, tabula-
tion, 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 inter-
pretative reports of investigations published by the Florida Bureau of
Geology and the U. S. Geological Survey, Data collected during an
investigation and prior to publication are available from the District
Chief, U. S. Geological Survey, 903 W. Tennessee St., Tallahassee,
Florida, 32304, and from the Chief of the Bureau of Geology, Box
631, Tallahassee, Florida, 32302.
taken from automatic water-stage recorder charts, pressure gages, and
made by 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 (appendix) summarizes well-data and water-level
information for the several aquifers. Well data include theaquifer,
depth of well, and depth of casing. The items: "Year record began" .
and "Frequency 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 most areas and records during that
period constitute a base for comparison from year to year. The
annual change of water level in the Floridan Aquifer, May 1967-May
1968, is illustrated by figure 2. Highest and lowest water levels of
record prior to 1967 are given in the table. Generally, highest and
lowest levels are highest daily levels if taken from recorder charts.
The range of fluctuations for 1967 and 1968 are shown under
"Annual range."

WELL-NUMBERING SYSTEMS
Two well-numbering systems are used in this report: serially by
counties, and grid-coordinate, based on latitude and longitude of the
well location. Frequently both numbers have been assigned to the
well; e.g., a well number may be shown as 20(008-537-2). This af-
fords a tie-in with water-level data published previously under well
number 20 in Bay County with date 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, High-
lands, 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. Two types of well numbers are used in
Table 1: a seven-digit numbering system and a nine-digit numbering
system.
The seven-digit 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 minutes that define the longitude on the east side of a 1-minute
quadrangle; 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

The first two series of three numbers each of the nine-digit well
number denotes latitude and longitude as explained under the
seven-digit well number. The third series of numbers in the nine-digit
well number gives the location of the well in a 1-minute rectangle
which has been divided into quarters, sixteenths and sixty-fourths.
The first digit of the series locates the well within the quarter
numbered 1, 2, 3, and 4 in southwest and southeast. Similarly, the
second digit locates the well within the quarter-quarter tract
numbered in a like manner -1, 2, 3, and 4. Finally, the third digit of
the series gives the quarter-quarter-quarter tract in which the well is
located numbered likewise 1, 2, 3, and 4. The locations of wells with
seven and nine digit numbers are diagrammatically shown in figure 3.

PRINCIPAL AQUIFERS

Ground-water supplies for agricultural, industrial, and municipal
uses 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. Th-geraizelr areal-

The Floridan Aquifer, which underlies all of the state, is the
principal source of water in central, northern, and most of north-
western Florida. Areas of artesian flow and the potentiometric
surface of the Floridan Aquifer is illustrated by figure 4.. Highly
mineralized water precludes the use of the Floridan Aquifer as a
source of potable water in some coastal areas and in most of
southern Florida. In these 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 irrigation. 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 supplies, of
ground water for industries and municipalities. The aquifer extends

lowest during May or June in most areas and records during that
period constitute a base for comparison from year to year. The
annual change of water level in the Floridan Aquifer, May 1967-May
1968, is illustrated by figure 2. Highest and lowest water levels of
record prior to 1967 are given in the table. Generally, highest and
lowest levels are highest daily levels if taken from recorder charts.
The range of fluctuations for 1967 and 1968 are shown under

NP denote Geological Survey wells, supply wells, fire wells, and
National Park Service wells, respectively. In Dade, Escambia, High-
lands, 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

the City of Pensacola was about four times that of 1945. Total
yearly municipal pumpage at Pensacola increased from about 1,500
million gallons per year (mgy) in 1945 to 5,970 mgy in 1968.

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 5
shows locations of observation wells selected from the hydrologic-
data network for which hydrographs are given in this report, and
table 1 (appendix) presents data on 13 wells in Escambia County and
3 wells in Santa Rosa County. Figure 7 shows fluctuations and long-
term trends of artesian water levels in the sand-and-gravel aquifer in
the Pensacola area from 1960 through 1968.

Comparison of the hydrographs for the period 1967-68 reveals
that while water levels at the end of 1968 declined in some areas in
central and southern Escambia County they remained essentially at
1965-66 levels near Cantonment and at Pensacola. Declines ranged
from about 12 feet in well Escambia 46 near Ensley to about 4 feet
in well Escambia 62 at Pensacola. At the end of 1968, levels at
Ensley had declined to approximately those of the 1954-56 drought
while levels near Cantonment and at Pensacola remained 8/2 and 10

FT. WALTON AREA

The Ft. Walton area includes the Ft. Walton Beach area and
Eglin Air Force Base. The rate of growth of industry and population
is accelerating. Pumpage from the Floridan Aquifer for all uses is
about 10.0 million gallons per day (mgd). 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
9, shows a maximum decline of 109.0 feet from 18.5 feet above land
surface in 1947 to 90.5 feet below land surface in July 1967. In

entirely from surface water from the Deer Point reservoir. Cessation
of pumping of ground water by Panama City and a change in the site
of the source of ground-water supply for the pulp industry allowed
ground-water levels to rise sharply during 1967-68 in spite of a rain-
fall deficiency of nearly 30 inches in the area. Levels at Panama City
rose about 42 feet, from 66 feet to 24 feet below land surface during
1967-68 in well Bay 7. The hydrograph of this well is shown on
figure 13. The areal rise of water levels at Panama City and vicinity is
illustrated on figure 14.
Regional rainfall deficiency in northwestern and northern
Florida, which began in the DeFuniak-Caryville-Marianna areas in
1966 and really intensified and spread as far south as Apalachicola
and eastward to Madison and Lake City during 1967-68, is
graphically reflected by the sharp decline of ground-water levels in
observation wells in much of the affected area.

NORTHERN AND NORTH-CENTRAL FLORIDA

The northern and north-central Florida section extends from
the Apalachicola River eastward to the Atlantic Ocean and from the
Georgia line southward to the latitude of Ocala, figure 15, and
includes 24 counties and parts of Levy, Marion, and Volusia
counties. This section includes two areas undergoing rapid expansion
in population and industry the Tallahassee area and the Jackson-
ville-Fernandina area.
The Floridan Aquifer is the principal source of ground-water
supply in coastal areas in eastern St. Johns, Flagler and Volusia
counties. Another important source of water in these areas is a
shallow, nonartesian, sand-and-shell aquifer.

TALLAHASSEE AREA

The Tallahassee area includes central Leon County and the City
of Tallahassee. The area is primarily residential with only sparse light
industry.
The principal water user, the City of Tallahassee, supplies water
for municipal use to the most rapidly growing residential and educa-
tional complex in northern Florida. Since 1945, annual municipal
pumpage at Tallahassee has increased about 457 percent from 850
mgy to about 3,888 mgy. Figure 16 shows pumpage for the City of
Tallahassee during 1945-68.

The principal source of ground-water supply in western coastal
and central peninsular Florida is the Floridan Aquifer, while in the
eastern coastal area the nonartesian shallow-sand aquifer is the chief
source of water supply. In central peninsular Florida, the level in well

LAKELAND AREA

In the Lakeland area, ground water is being pumped at an
increasing rate commensurate with the economic growth of the area.
Municipal pumpage increased from about 1,250 to 4,378 mgy during
1945-68. From 1945 through 1955 pumpage increased 83 percent
with an average increase of 113 mgy. During 1956 through 1966
pumpage increased about 98 percent with an average rate of increase
of 206 mgy. Annual pumpage reached a maximum of 5,300 million
gallons in 1967, then declined to 4,738 million gallons in 1968.
Figure 27 shows the total yearly municipal pumpage at Lakeland for
1945-68.
The marked decline of water levels in the Floridan Aquifer in
the vicinity of Lakeland is shown in figure 28. A maximum decline
of about 20 feet. in well Polk 45 occurred during October 1960
through May 1962. During 1964-68, the decline was resumed with
levels falling to the lowest of record in 1968.
In northern Polk County, water levels declined to new record
low levels in many areas during 1960-62, rose shaIply in 1963, then
declined to new record low levels in 1965, 1967, and 1968. Levels in
the Floridan Aquifer declined nearly 31 feet during 1964-68 in well
Polk 45 in the heavily pumped area south of Lakeland. In contrast,
artesian levels in well Polk 44 near Davenport in northeastern Polk
County declined only about 3.0 feet during the same period. Levels
in well Polk 47 in the nonartesian aquifer near Davenport declined
about 2.0 feet to a new low of record in 1968. The continuing
downward trend of levels in artesian and nonartesian aquifers was
accentuated by rainfall deficiency and increased pumping in northern
Polk County during 1967 and early 1968. Precipitation recorded at
Lakeland shows deficient rainfall in the Lakeland area during 1961
through early 1968. During 1967-68 water levels ranged from 4 feet

CAPE KENNEDY AREA

One of the most rapidly growing areas in the state is the Cape
Kennedy area, which includes the cities of Cocoa, Cocoa Beach, and
Titusville in Brevard County. In this area, water in the Floridan
Aquifer is generally brackish and is used primarily for irrigation.
Water-level fluctuations in eastern coastal Florida in Brevard, Indian
River and St. Lucie counties are shown in figure 37.
Hydrographs of wells in Brevard County generally show a
long-term downward trend of artesian levels in the Floridan Aquifer.
From 1946 through 1968 artesian levels have declined nearly 10 feet
in well Brevard 79 in northern Brevard County and about 10 feet in
well Brevard 159 on the northern end of Merritt Island. Levels in
wells 79 and 148 declined to new record low levels in 1968. For the
first time of record well Brevard 79 ceased to flow during the first
five months of 1968. Near Cocoa, the artesian level in well Brevard
148 declined below land surface in May 1968, at which time the well
ceased to flow for the first time of record. In contrast, nonartesian
levels in the shallow sand aquifer in Indian River and St. Lucie
counties have generally shown no downward trend during the period
of record. Levels in wells Indian River 25 and St. Lucie 42 declined
about 5 feet and 2 feet, respectively, during 1965-67. During 1968,
levels in both wells were about average for the period of record.
Increased water use for irrigation and deficiency of rainfall
during 1967 contributed to the 1967 decline of artesian levels in
many areas in Brevard County. During 1968, levels rose in response
to above normal rainfall. Annual rainfall at Titusville was 7.00 inches
below normal during 1967, and 8.41 inches above normal rainfall
during 1968.

SARASOTA-BRADENTON AREA

The Sarasota-Bradenton area includes Manatee and Sarasota
counties in southwestern coastal Florida. Principal economic
activities in the area are agricultural-truck and citrus farming and
stock raising. The coastal section, however, is rapidly developing as a
retirement and year-round tourist center.
Figure 38 shows trends and fluctuations of water levels in
observation well Sarasota 9.
The hydrograph shows a well-defined decline of artesian water
level in the Floridan Aquifer. Levels in well Sarasota 9 have declined
26.07 feet from 5.20 feet above land surface in March 1931, the

46 BUREAU OF GEOLOGY

highest recorded level, to a new record low level of 20.87 feet below
land surface in May 1968. Levels in well Sarasota 9 have been declin-
ing at an average rate of about 0.5 foot per year since 1931.

The hydrograph of well Sarasota 9 shows the decline is con-
tinuing and that the range of fluctuations has increased, particularly
during 1967-68. The regional extent of the decline is shown by
hydrographs of well Hillsborough 30 (figure 25) and of well Sarasota
9 (figure 38).

The principal source of water supply in the Stuart area is the
nonartesian shallow-sand aquifer. Trends of water levels in well
Martin 147 at Stuart are shown in figure 41. The hydrograph of well
Martin 147 shows a slight downward trend of nonartesian levels.
Levels declined to a record low level of about 2 feet above mean sea
level in the springs of 1962, 1963 and 1965. The declines were
caused, in part, by increased pumping in the Stuart well field.
Although pumpage increased during 1965-66, water levels declined,
then rose in response to above average rainfall during 1967-68.

FT. LAUDERDALE AREA
The Ft. Lauderdale area includes the populous coastal part of
Broward County extending from the Deerfield-Boca Raton area in
the northern part of Broward County to the Hollywood area in the
southern part of the county. Long-term downward trends of water
levels in the Biscayne Aquifer in and adjacent to the Ft. Lauderdale
area are shown by the hydrograph of well Broward S329 at Ft.
Lauderdale (figure 46).
The Biscayne Aquifer contains salty water in areas adjacent to
the coast and along tidal canals. Figure 47 shows graphs of the
chloride content of water in wells Broward G515, G820A, and S830,
all in the vicinity of the Ft. Lauderdale Dixie well field. The chloride
content of water in well Broward S830 decreased from about 3,700
mg/1 in 1947 to about 50 mg/l in 1958. From 1958 through 1968,
chloride content increased to about 2,000 mg/1. The chloride, content
of well Broward G515 increased from slightly over 500 mg/1 to 750
mg/1 in 1955 then decreased gradually to about 700 mg/l in 1968.
The chloride content of well Broward G820A decreased from a high
of 85 mg/l in 1956 to 15 mg/l in 1961, then increased to 33 mg/l in
1967, and decreased in 1968 to 22 mg/l.

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 39.
Water-level observations were made as early as 1933 at Home-
stead in well Dade S196A. The long-term record of water-level
fluctuations at Homestead is shown in figure 46. Figure 48 shows
trends of water levels and rainfall recorded at Homestead Experi-
mental Station 1965-68.
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
G596, G618, and G620, figures 49 and 50.
In the vicinity of Miami, fluctuations of ground-water levels in
the Biscayne Aquifer are illustrated by hydrographs of wells Dade
G10 about 5 miles west of Miami, Dade S19 at Miami Springs (figure
48), and well Dade F179 at Miami (figure 45). The water level in well
Dade S19 is affected by pumping in the City of Miami municipal well
field.

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. Sea water is contained in the seaward reaches of the
Biscayne Aquifer 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.

INFORMATION CIRCULAR NO. 68

Generally, chloride content of ground water increased in most
areas of Dade County during 1967-68.
In northern Dade County, chloride content of ground water in
the Biscayne Aquifer in well Dade S68 at Miami Springs well field
near Miami increased from about 30 to nearly 50 mg/1. Chloride
content in well Dade D151, North Miami, increased from 59 to 105
mg/l in early 1968, then decreased to 31 mg/1 in September 1968.
Chloride content in wells Dade F64 and F296 remained essentially
the same as in 1965-66. However, chloride concentration in well
Dade F64 had a wider range of fluctuation than that of well Dade
F296 during 1967-68.
In southern coastal Dade County, chloride content generally
remained at low concentrations in most areas during 1967-68.
Chloride content decreased slightly in well Dade S529. In contrast,
the chloride content of well Dade G469 near the coast south of
Miami increased from 8,700 mg/l in 1967 to 9,400 mg/l in late 1968.
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 salty water contamination has been
solved. In many areas where contamination existed the situation has
been alleviated by water control. The effectiveness of the method of
control is graphically illustrated in figure 51 by the chloride graph of
well Dade S529.

highest recorded level, to a new record low level of 20.87 feet below
land surface in May 1968. Levels in well Sarasota 9 have been declin-
ing at an average rate of about 0.5 foot per year since 1931.

The hydrograph of well Sarasota 9 shows the decline is con-
tinuing and that the range of fluctuations has increased, particularly
during 1967-68. The regional extent of the decline is shown by
hydrographs of well Hillsborough 30 (figure 25) and of well Sarasota
9 (figure 38).
