WATER LEVELS IN
ARTESIAN AND NONARTESIAN
AQUIFERS OF FLORIDA, 1969-70.



By
Henry G. Healy




INTRODUCTION

This report summarizes the trends and fluctuations of ground-water lev-
els in wells tapping the principal aquifers in Florida during 1969-70 and in-
cludes the following: (1) hydrographs of 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.
The "Index to Water Resources Data Collection Stations in Florida,
1961" Florida Geological Survey Special Publication No. 11, lists the obser-
vation wells for which records are available. The index was prepared by the
U.S. Geological Survey in cooperation with the Florida Geological Survey,
(now the Bureau of Geology, Florida Department of Natural Resources)
and includes the location, name of aquifer, and type and period of records
available for 3,656 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, short-
ages will occur and may become critical in some areas. In coastal areas, de-
clining water levels may allow salt water to encroach, and shortages could
result from deterioration in quality as well as from the reduction of quan-
tity of water available. In order to prevent future shortages developing from
increasing demands, 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 ap-
praisal.
The principal objective of the investigations of the Water Resources
Division of the U. S. Geological Survey is to appraise and to evaluate the






2 BUREAU OF GEOLOGY

nation's water resources. Although many types of ground-water investi-
gations are carried out on a statewide basis throughout the nation, the col-
lection and compilation of hydrologic data constitute an important part of
the water-resource studies.
Objectives of the hydrologic data-collection program in Florida in-
clude: the evaluation 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 de-
termine 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 basic research. The hydrologic-data program pro-
vides the foundation information necessary for the successful and mean-
ingful accomplishment of water-resource 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 1970 included about 1,100 wells in the 67 counties of the
state. Figure 1 shows the locations of selected observation wells in the
statewide network. Table 1 (see appendix) lists data on 364 observation
wells selected from the statewide network of wells.
Thy hydrologic-data program consists of the collection, tabulation, and
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 interpre-
tative 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. Geolog-
ical Survey, 903 W. Tennessee Street, Tallahassee, Florida 32304.
The water-level data used in this report represent measurements taken
from automatic water-stage recorder charts, pressure gages, and made
manually by tape. Generally, measurements made by tape and automatic
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. Meas-
urements for January, May, and September are used if stage recorder or
bimonthly periodic water-level measurements are available; January and
May measurements are used if the frequency of measurement is semian-
nual. May measurements are used if the frequency of measurement is an-
nual.
Table I (appendix) summarizes well data and water-level information for
the several aquifers. Well data include the aquifer name, depth of well and
casing, the year that the record began, and the frequency of water-level
measurement. Water-level information includes the highest and lowest May

measurement for the biennial period of the report, and the biennial change.
Generally, highest and lowest levels are highest daily levels if taken from re-
corder charts. The months May or June are used because records are avail-
able for these months for most of the wells. Also, during these two months,
ground-water levels are lowest in most areas and measurements during that
period are the most reliable in comparing water-level changes from year to
year. The annual change of water levels in the Florida aquifer, May 1969-
May 1971 is illustrated on figure 2.


WELL-NUMBERING SYSTEMS

Four well-numbering systems are used in this report: serially by coun-

sixteen digits. Frequently, especially with older wells more than one sys-
tem of numbers have been assigned. In table 1, for example, well Bay 7 is
shown as 7(010-541-1) in addition to having a sixteen digit number. The
use of different numbers for each well is necessary as this affords a tie-in
with water level data published previously under the different well numbers.
The grid-coordinate well-numbering systems in Florida are derived from
latitude and longitude coordinates.-
The seven-digit well number is a composite of three numbers separated
by hyphens: the first is composed of the last digit of the degree and the two
digits of the minute thatdefine the latitude on the south side of the 1-min-
ute quadrangle; the second number is composed of the last digit of the de-
gree 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 quad-
rangle north of the 28035' parallel of latitude and west of the 81005'
meridian of longitude.
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 num-
ber. 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 south-
east. Similarly, the second digit locates the well within the quarter-quarter

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.
The sixteen-digit well number consists of degrees, minutes, and sec-
onds of latitude and longitude and a sequential number which indicates the
number of the well in a 1-second square quadrangle. Figure 4 shows a
schematic explanation of the sixteen-digit well numbering system.
The numbers for some wells listed in table 1 have 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 same number without the letter suffix. In Orange County, the
letter suffixes B and C denote shallow wells drilled in the vicinity of
well 47.

PRINCIPAL AQUIFERS

Ground-water supplies for agricultural, industrial, and municipal uses in
Florida are obtained 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.
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 Flor-
ida. In these areas, shallow artesian and nonartesian aquifers are the source
of supply. Areas of artesian flow and the potentiometric surface of the
Floridan Aquifer is illustrated by figure 5.
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 use-
fulness 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 beneath all of Escambia
and Santa Rosa counties and part of western Okaloosa County.
This report of ground-water conditions has been divided into four sec-
tions as follows: (1) northwestern Florida; (2) northern, northeastern, and
north-central Florida, (3) central Florida; and (4) southern and southeastern
coastal Florida.



NORTHWESTERN FLORIDA

The northwestern section includes the Florida panhandle extending from

The principal sources of ground-water supply in this section are the
sand-and-gravel aquifer in Escambia and Santa Rose counties and the
Floridan Aquifer in Okaloosa County eastward to the Apalachicola River.
Minor supplies of ground water are obtained from shallow nonartesian
aquifers.
Pensacola, Ft. Walton Beach, and Panama City are growing rapidly
in industry and population.

like many areas in the State, is undergoing rapid economic development
accompanied by increasing use of water by industry and municipalities.
For example, figure 7 shows that the total 1970 pumpage for the city of
Pensacola was about four times that of 1945. Total yearly municipal pump-
age at Pensacola increased from 1.470 mgy (million gallons per year) in
1945 to 6,313 mgy in 1970 (figure 7).
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 6 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 4 wells in Santa Rosa County. Figure
8 shows fluctuations and long-term trends of artesian water levels in the
sand-and-gravel aquifer in the Pensacola area from 1945 through 1970.
Hydrographs (fig. 8) and table 1 (appendix) show that water levels
declined in some areas during 1969, but rose in most areas in 1970 in
central and southern Escambia County. In those areas affected by pump-
ing, 1970 water levels ranged from less than 1 foot to 234 feet lower than
those of 1969. End-of-year levels near Cantonment and well Escambia 45
rose less than 1 foot above 1969 levels. Water levels near Ensley and well
Escambia 46 rose nearly 4 feet above those of 1969.
In the coastal area at Pensacola, at the end of 1970 the artesian water
level in well Escambia 62 was less than 1 foot above that of January 1969.
Trends and fluctuations of artesian levels in well Escambia 62 and depar-
tures from monthly average rainfall at Pensacola, 1969-1970, are shown on
figure 9.


FT. WALTON BEACH 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 mgd (mil-
lion gallons per day). As a result of continuing heavy pumping, water lev-
els have declined in about a 640-square mile area since 1936.
The hydrographs of well Okaloosa 3 at Fort Walton Beach and wells
Okaloosa 25 and 31 about 15 miles north of Fort Walton Beach show the
decline of ground-water levels in a broad area as shown in figure 10. From
August 1936 to May 1970 the level in well Okaloosa 3 declined 110.8 feet,
from 46 feet above land surface in 1936 to 65.2 feet below. The areas
where, in the vicinity of Fort Walton Beach, decline in artesian level has
occurred is shown on figures 11 and 12.

PRINCIPAL AQUIFERS

Ground-water supplies for agricultural, industrial, and municipal uses in
Florida are obtained 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.
Highly mineralized water precludes the use of the Floridan Aquifer as a

NORTHERN, NORTHEASTERN, AND NORTH-CENTRAL
FLORIDA

The northern, northeastern, 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, and includes 24 counties
and parts of Levy, Marion, and Volusia counties, as shown on figure 15.
This section includes two areas undergoing rapid expansion in population
and industry theTallahassee area and the Jacksonville-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 Tal-
lahassee. 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 educational com-
plex in northern Florida. Since 1945, annual municipal pumpage at Talla-
hassee has increased about 420 percent, from 850 mgy to 4,393 mgy in
1970. Figure 16 shows pumpage for the city of Tallahassee during
1945-70.

At Dunedin, the chloride content of well Pinellas 166 decreased during
1969-70 and reached the lowest concentration since 1966. During 1969-
70, the chloride content ranged from 575 mg/1 (milligrams per liter) in
January 1969 to 122 mg/1 in May 1970.
At Bay Pines, during 1969-70, the chloride content in water from well
Pinellas 592 fluctuated from 625 mg/1 in January 1969 to 1750 mg/1
during May 1969. During 1970, chloride ranged from 860 mg/1 in Jan-

water from both wells had a narrower range of fluctuations in 1969-70
than 1967-68.



LAKELAND AREA

In the Lakeland area, ground water is being pumped at an increasing
rate commensurate with the economic growth of the area. Since 1945,
municipal pumpage increased from about 1,250 to 5,237 mgy. Annual
pumpage reached a maximum of 5,300 million gallons in 1967, decreased
to 4,486 million gallons in 1969, as shown on figure 27, and then increased
to 5,237 million gallons in 1970.
Fluctuations of water levels in the Floridan Aquifer in the vicinity of
Lakeland are shown in figure 28. The level in well Polk 45 remained about
average during 1969, but declined about 17 feet during early 1970, then
rose during June, July and August.
In many parts of northern Polk County, water levels declined to new
record lows during 1960-62, rose sharply in 1963, then declined to still
lower levels in 1965, 1967, and 1968. The level in well Polk 45 tapping the
Floridan Aquifer declined nearly 31 feet during 1964-68 in the heavily
pumped area south of Lakeland. The artesian level in well Polk 44 near
Davenport in northeastern Polk County rose 2.0 feet during 1969 then
declined an equal amount in 1970. Levels in well Polk 47 in the nonartesian
aquifer near Davenport rose 2.5 feet to the highest level of record since
1949. The trend of levels in artesian and nonartesian aquifers was
generally slightly downward in comparison with sharp declines of 1967-68,
which were primarily caused by deficient rainfall and increased pumping
in northern Polk County during 1967 and early 1968. At Lakeland rainfall
was deficient during 1961 through early 1968. Rainfall ranged from 1.6
inches above average in 1969 to 4.8 inches below average in 1970. Long-

near Frostproof, and well Highlands 10 near Sebring. During 1970, levels
in both wells rose to the highest of record since 1948. In sharp contrast,
the level in well Polk 51 in the Hawthorn Aquifer near Frostproof declined
sharply during 1970, but by the end of 1970 had risen nearly to 1968 levels.

Winter Park increased markedly. At Orlando, total yearly pumpage in-
creased 411 percent during 1945-70 and at Winter Park 377 percent
during 1951-70. At the Cocoa well field, the decrease in total annual pump-
age during 1969-70 reflects to a degree the diminished activity at Cape
Kennedy.

are agricultural-truck and citrus farming and stock raising. The coastal
section, however, is rapidly developing as a retirement and year-round
tourist center.
The hydrograph of observation well Sarasota 9 tapping the Floridan
Aquifer shows a well-defined decline. The water level declined 26.07 feet,
from 5.20 feet above land surface in March 1931, the highest recorded
level, to a record low of 20.87 feet below land surface in May 1968. During
1969-70 the level declined seasonally and fluctuated in response to rainfall
and areal pumping.
The hydrograph of well Sarasota 9 shows the decline is continuing and
that the range of annual fluctuations reached a maximum during 1967-68.
The regional extent of the decline is shown by hydrographs of well Hills-

In the coastal areas of Martin and Palm Beach Counties and in south-
western coastal Florida and inland areas, nonartesian shallow-sand aquifers

BUREAU OF GEOLOGY


The principal source of water supply in the Stuart-West Palm Beach area
is the nonartesian shallow-sand aquifer. The hydrograph of well Martin 147
at Stuart (fig. 41) shows the downward trend of nonartesian water levels.
Levels declined to a record low of about 2 feet above mean sea level in the
spring of 1962, 1963, and 1965. During 1968 and 1970 levels declined
below 1 foot above mean sea level, and at the end of 1970 the level declined
to nearly .-ean sea level. The declines were caused in part by increased
pumping in the Stuart well field and rainfall deficiency late in 1970. Figure
43 shows trends of water levels and departures from normal monthly pre-
cipitation recorded at Stuart, 1965-70.
The chief source of water supply in southern Palm Beach, Broward,
and Dade Counties is the Biscayne Aquifer. Figure 44 shows the trends
and fluctuations of end-of-month wdter level in well Palm Beach 88 and de-
partures from normal monthly precipitation data at West Palm Beach.
Fluctuations of water levels for several selected wells are shown in figures
45 and 46.


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 the 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 (fig. 46).
Adjacent to the coast and along tidal canals the Biscayne Aquifer con-
tains salty water. Figure 47 shows graphs of the choloride 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
G515 is increased slightly over 500 mgl/ (milligrams per liter) to 750
mg/1 in 1955, then decreased to about 700 mgll in 1968. During Decem-
ber 1970 chloride content increased to a record high of 870 mg/1. The
chloride content of water from well Broward G820A decreased from 85
mg/1 in 1956 to 15 mg/1 in 1960, then gradually increased to 33 mg/1 in
1967. Chloride content ranged from 34 mg/1 in October 1969 to 24 mg/1
in October 1970. The chloride content of water in well Broward S830
decreased from about 3,700 mg/1 in 1947 to 50 mg/1 in 1958, then
gradually increased to 2,750 mg/1 in 1969, then decreased sharply to
1,760 mg/1 late in 1970.
Contours of ground-water levels in the Biscayne Aquifer in eastern
coastal Broward County for May 1969 and May 1970 are shown on

INFORMATION CIRCULAR NO. 73


Declines, which ranged from less than 1 foot to nearly 2 feet, were the
result of rainfall deficiencies in the latter half of 1970.
In the vicinity of Miami, fluctuations of water levels in the Biscayne
Aquifer are illustrated by hydrographs of wells Dade G10 west of Miami,
Dade S19 at Miami Springs (fig. 51), and well Dade F179 at Miami (fig.
46). The water level in well Dade S19 is affected by pumping in the city of
Miami municipal well field. Total yearly pumpage for Miami is shown in
figure 54.
Generally, chloride content of water from the Biscayne Aquifer de-
creased in most areas of Dade County during 1969-70. In northern Dade
County, chloride content of water from well Dade S68 at Miami Springs
well field near Miami decreased from 50 to 29 mg/1. Chloride content
in water from well Dade D151, North Miami, decreased from 105 to 6 mg/l
in the fall of 1969, then increased to 28 mg/1 in January 1970 (fig. 53).
The chloride content in water from well F296 remained nearly the same as
in 1969-70 (fig. 47).
In water from wells in most of southern coastal Dade County, chloride
content generally remained low during 1969-70. Chloride content in water
from well Dade S529 remained about the same from 1968 through the
period of record (fig. 53).
In the Miami area, as in other coastal areas, the presence of salt 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 sea water has encroached into the aquifer through the years.
In the Miami area, the contamination of the Biscayne Aquifer by the
encroachment of salt water is an ever-present problem. In some places
through intensive practice of water control, salt-water contamination has
been prevented. In other areas, where contamination already existed,
the situation has been relieved by water control. The effectiveness of the
method of control is graphically illustrated by the chloride graph of well
Dade S529, as shown in figure 53. Chloride content of water from this well
decreased from nearly 3,000 mg/1 in 1947 to less than 500 mg/1 in 1964.

section, however, is rapidly developing as a retirement and year-round

The hydrograph of observation well Sarasota 9 tapping the Floridan
Aquifer shows a well-defined decline. The water level declined 26.07 feet,
from 5.20 feet above land surface in March 1931, the highest recorded
level, to a record low of 20.87 feet below land surface in May 1968. During
1969-70 the level declined seasonally and fluctuated in response to rainfall
and areal pumping.
The hydrograph of well Sarasota 9 shows the decline is continuing and
that the range of annual fluctuations reached a maximum during 1967-68.
The regional extent of the decline is shown by hydrographs of well Hills-

DeSoto County arid covers an area of about 17,500 square miles. The re-
gion and locations of selected observation wells for which hydrographs are
presented are shown on figure 39.
In the coastal areas of Martin and Palm Beach Counties and in south-
western coastal Florida and inland areas, nonartesian shallow-sand aquifers
are the chief sources of supply. In Broward and Dade Counties, the Bis-
cayne Aquifer is the principal source.
