INTRODJUCTIOr

This investigation was made for the purpose of manping the locations

of the numerous drainage and sanitary wells in Orlando and viinity, to

compile data ron.erning these wells, and to assemble geologic and hydro-

login information relative to the effect of such wells on the ground-water

resources of this area.

The investigation was under the general supervision of 0. E. Meinzer,

Geologist in Charge of the Division of Ground Water, U. S. Geologi'.al

Survey, and Herman Gunter, Director of the Florida Geological Survey, and

under the immediate supervision of V. T. Stringfield and H. H. Cooper, Jr.,

of the U. S. Geological Survey. Captain A. B. DeWolf, of the Corps of

Engineers, U. S. Army, made preliminary arrangements for the investigation

and gave many helpful suggestions.

During the field work much valuable assistance was given by Lt. Col.

J, P. Larsen and Exr. D. D. Riddle of the U. S. Engineers Offie at the

Orlando Air Base. Mr. F. L. Holland, of the Orange County Road and Bridge

Department, supplied information regarding County-owned wells, and aided

in the location of these wells. 'r. A,.B. Herndon, City Engineer, and

,r. Jesse Burkett, of the Orlando City Engineers Offi'e, furnished infor-

mation nonierning City-owned drainage and sanitary wells, and furnished

pumping equipment and operators during the well exploration. Valuable

suggestions were made by Miessrs. J, B.,Iiiller and Fred Eidsness of the

Bureau of Sanitary Engineering, Florida State Board of Health. Well logs

and cuttings of numerous wells were supplied by Mr. Clyde Freeman, of

Libby and Freeman Company, and Mr. J, E. Cousins, of Layne-Atlantii

Company, Mr, .Freeman also gave freely of his time to aid in the location

of many of the wells.. The altitudes of the measuring points








on many wells used for water-level observation were determined by

leveling parties supplied by the U. S. Engineer Department.


TOPOGRAPHY AND DRAINAGE


Orange County may be roughly divided into three physiographic

regions. The eastern part of the County, between the St. Johns and

E-onloikhatnhee Rivers, is a relatively flat lowland ranging in

altitude from about 10 feet along the St. Johns River to as much as

60 feet in the area just east of the Econlookhathhee River. This

lowland contains many swamps and marshy areas. Most of the lowland

is drained by eastward flowing tributaries of the St. Johns River, but

the extreme western part is drained by short tributaries of the

Econlookhat 1hee.

The region west of the Ennnlookhatehee River, extending nearly

to Orlando, consists of a series of northwest trending, parallel,

elongate ridges and intervening elongate low areas. Altitudes in

this region range from 50 to 80 feet. The northern portion of the

region is drained by a branch of the E.onloe.khatn.hee, and the southern

portion is drained into Lake Hart, Lake Mary Jane, and other smaller

lakes

Except for the lowland area in the headwater region of the Wekiva

River, most of Orange County west of the region of parallel ridges

is a rolling upland whinh extends northward and westward into Seminole

and Lake Counties, and southward and westward into Osneola and Polk

altitude from about 10 feet along the St. Johns River to as much as

portion is drained into Lake Hart, Lake Mary Jane, and other smaller

Except for the lowland area in the headwater region of the Wekiva

River, most of Orange County west of the region of parallel ridges

is a rolling upland whinh extends northward and westward into Seminole

and Lake Counties, and southward and westward into Osneola and Polk









Counties. Within Orange County, the upland ranges in altitude from

70 to 140 feet and has a maximum local relief of about 50 feet. This

upland area contains numerous closed depressions, many of which con-

tain lakes or ponds. Some of the depressions, especially the steep-

walled ones, appear to have originated as the result of lo.al sub-

sidenre of underlying formations consequent to the collapse of caverns

and solution channels in the substratal marls and limestones. There

is very little surface drainage in the upland area. vith the exception

of drainage into Howell Creek and Wekiva River, which flow northward

and eastward to the St, Johns River, and of drainage into Shingle and

Reedy Creeks, which flow southward to the Kissimmee River Basin, all

natural drainage is into the closedd depressions, Probably many of

these depressions are drained by seepage through pervious material

into the underlying limestone.

formations. The closed depressions in the upland, which might be

expected to provide, exposVres, are either filled with water or mantled

Sby sand. Sandy, phosphatic limestone of the Hawthorn formation is











exposed at Rook Spring, about five miles north of Apopka, and red

clays, which are probably residual from the Hawthorn,' are exposed in

several clay pits in the northw~ternr part of the County.

In the nbsenco of sufficient exposures, information regarding

the characteristics of underlying formations must be obtained from

studies of well cuttings. Such studies indic'-to, that the formations

penetrated by wells in Orarlge County and ndj.acent regions are, in

nsconding ordor; middle Eocene limestone, Oc9la limestone (upper

Eocuno), Hawthorn formntiou (lovwr Miocene), rmrl b..ds which n.-y be

of Choctnwhatohoe r : (upper fiocenia), and surficiil sRnd t'nd clay

(Ploistocenu and Rec..;nt).


Eocene


In public-atisns that -:pposar.d prior to 1937, all Eocene iime-

stones penetrated by we31s in central Florida were generally referred

to the Ocala. Although it was genera-lly recognized that the lower

part of the section penetrated contained bads older than typical Ocala

limestone, the term Ocal! had not been restricted, and.the contact

between the Ocala and underlying beds had not boon defined.

Stringfield (1936) stated:

"The lithilogy of the Ocala and the underlying Eocene
rooks is similar, and it is therefore necessary to dis-
tinguish the two units on the basis of a study of the
fossils collected from the well cuttings. No diagnostic
fossils have beeon reported near the contact, and the lower
limit of the Ocala has therefore not been definitely
determined."

Stubbs (193?) tentatively assigned a middle Eocene age to a zone which

he called the "Coskinolina Zone." According to Stubbs, this zone

".. lies directly below the Ocnla formation" and well cuttings

from it ". .. revealed a predominance of thi Foraminifer Coskinolina

and an absence of typical Ocaln Foraminifera." The forms referred

to Coskinolina by Stubbs are now recognized as Dictyoconus cookei

(Moberg). Cole (1941 and 1942), reporting on wells in Polk and Levy

Counties, used the uppermost occurrence (within the Eocene) of

Dictyoconus cookei (Moberg) to define the upper limit of the middle

Eocone. At the same time, he divided the middle Eocene into seven

zones, the uppermost of which he called the Dictyoconus cooksi zone,

Later (1944) Cole included this zone, with others, in the Lisbon

formation as extended westward from Mississippi and Alabama.


Middle Eooene


Logs of three wells in Orange County that are 1,000 feet or more

in depth indicate that the middle Eocene limestone is at least 750

feet thick and that it may be roughly divided into two distinct

portions.

The lower portion is at least 550 feet thick and consists of

light to dark brown, porous, recrystallized, dolomitic limestone,

with a few irregularly spaced beds or lenses of dense, reddish brown,

cherty limestone. Disseminated throughout this lower portion are

numerous minute inclusions of pyrite, and a few molds and casts of

small molluscs, Owing to recrystallization, however, the fossils

cannot be identified.









The upper portion is about 200 feet thick and consists almost

entirely of porous, white to aream, highly fossiliferous, forami-

niferal limestone, in which Diityoconus iookej is very abundant,

Interbedded through this upper portion are thin beds of light buff,

porous, renrystallized limestone.

The permeability of the middle Eonene limestones allows circu-

lation of water, and the circulating water has formed naverns and

channels which are often encountered in drilling. The recrystalliza-

tion so prevalent in these limestones is due to the precipitation of

material from mineralized solutions and the deposition of this

material in interstices in the rocks,


Ocala limestone


The term, Ocala limestone, is here applied to the Eocene lime-

stone above the top of the middle Eocene as defined by Cole (1941 and

1942). The Ocala is penetrated by most wells in Orange County, but a

few scattered wells, whith appear to have been drilled in sinkholes

or solution cavities, enter middle Eonene beds immediately beneath

the Hawthorn. In such wells the interval normally onnupied by the

Ocala and upper beds of the middle Eocene consists of a heterogeneous

mixture of Hawthorn marl and limestone with irregularly disseminated

small fragments of Unala and middle Eocene limestone (see well 82 in

figure 3). The logs of wells that penetrate the Onala indicate that

it ranges in thickness from. 4 to 120 feet. As the contact between

the Ooala and the underlying middle Eocene limestone appears to be
N.










conformable, the variations in thickness of the Ocala suggest that it

was subjected to surface erosion prior to the deposition of the

Hawthorn.

The O0ala in Oala in Orange County is similar to the Ocala exposed

in other parts of Florida and consists of white to cream, porous,

relatively pure limestone, composed almost entirely of foraminifera

tests, It also contains molds and lasts of larger molluscs and echi-

noids. The permeability of this limestone allows free nirnulation of

water, and the solvent action of the water has resulted in the formation

of subterranean cavities and channels.


Mionene

Upper Mionene


There is some uncertainty regarding the presence of upper Miocene

deposits in Orange County. Cooke and Mossom (1929) do not map, or

mention the oncurrence of, deposits of this age in this area.

Stringfield (1933) mentions the occurrenne of the upper Mimene

Chontawhatnhee formation in Orange County but does not give informa-

tion nonrerning its thickness or area extent.

A few of the wells in the County penetrate 30 to 40 feet of shell

marl immediately under the surfinial sand. This marl contains molluscs

and foraminifera which appear to be contemporaneous with Chontawhatthee

forms, but proof of this age relationship will require detailed exami-

nation of many well cuttings. The shell marl may represent highly

fossiliferous portions of the Hawthorn, or it may actually be a deposit







of Ohontawhatihee time. As the shell marl has been reported in only

a few wells, its area extent is not known. In the profiles ai.ompa-

nying this report (figs. 1, 2, and 3) this marl is tentatively

referred to the Hawthorn formation.


Hawthorn formation


The Hawthorn formation, whinh unionformably overlies the O'ala

limestone, consists of a series of sandy, phnsphatin marl beds and

interbedded layers of limestone. It ranges in thickness from 45 to

nearly 200 feet. The thickness is dependent upon the surface elevation

and the irregularities in the surface of the O.ala.

The lower part of the Hawthorn is predominantly a light buff to

greenish gray, silty, granular limestone whioh ncntains many small

brown phosphatio grains. This limestone appears to be interbedded

with thin layers of sandy phosphatin marl,

The upper part of the Hawthorn consists of alternating beds of

gray, sandy, phosphatin marl and very fine, thinly laminated, al-

nareous noly, A well indurated, coarsely nonglomeratin limestone is

penetrated at irregular intervals in many of the wells. This non-

;lonerate consists of a gray limestone matrix .nntaining quartz sand,

phosphate pebbles, fish teeth, and rounded, solution-pitted fragments

of bluish-gray limestone.

The only indurated rook exposed in Orange County is a nart of

the Hawthorn formation. Rook Spring, about five miles north of

Apopka, issues from a nave-like opening at the base of a vertical









bluff in which a thickness of about 15 feet of buff to brown, sandy,

phosphatic limestone is exposed. Wekiva Spring, about three miles

northeast of Apopka, also issues from an opening in the Hawthorn

formation, but the opening is belew the water level. Elsewhere in

the northwestern part of Orange County, rod clays, which are probably

residual from the Hawthorn, are exposed in several clay pits.

Some of the sand and limestone beds of the Hawthorn formation

are fairly permeable and will therefore yield small quantities of

water to wells. However, the Hawthorn also contains relatively im-

pervious layers of marl and clay which act as confining beds for the

artesian water in the Oola and middle Eocene limestones. Although

Rock Spring and Wekiva Spring issue from openings in the Hawthorn,

this formation may not be the source of the water. Probably the water

flowing from these springs comes from the Ocala aid middle Eocene

linmstones, and flows to the surface through crevices and solution

channels in the Hawthorn.


Pleistocene and Recent


Overlying all other formations in most of Orange County and large

portions of adjacent counties is a covering of unconsolidated sand

interbedded with clay, which ranges in thickness from a few inches

to nearly 100 feet. The sand yields small quantities of water to

shallow driven wells,









Structural Geology


Orange County lies on the southeast slope of the Ocala uplift,

where the general dip of the Ocala and middle Eocene limestones is

southward and eastward. Structural features cannot be determined from

the altitude of the upper surface of the Ocala because this surface is

irregular owing to solution and erosion. However, the top of the

middle Eocene is more regular, and its shape, as determined from

studies of well logs, suggests that a minor structural basin exists

in the vicinity of Orlando. Other minor .structural features may exist,

but they cannot be determined until more subsurface data is obtained.


GROUND 'ATER

General Conditinns


Small supplies of vwter are obtained from shallow wells ~fding

in the surficial sand, but the water from these wolls is often colored

and is susceptible to pollution by seepage from the surface. Also,

some wells obtain moderate quantities of water from pervious layers of

the Hawthorn formation. However, the principal water-bearing forma-

tions of Orange and adjacent courtties are the Ocala and middle Eocene

limestones.

The water in the Ocala and middle Eocene limestones is under

artesian pressure, that is, when the confining beds are perforated

it will rise in the well to a level higher than the top of the water-

bearing bed. In the lowlands along the St, Johns River, in eastern

Orange Uounty and northeastern Seminole County, and around the margins









of Lake Apopka, the water in wells penetrating the Eocene limestone

will rise above the land surface. Also water in wells penetrating

these limestone will rise above the surface in the lowlands of

Oscenla County in the headwater region of the Kissimmee River. Some

of the drainage wells in OrlandA and vicinity have flowed during

periods of heavy rainfall. In the summer of 1930, well 47, a drainage

well nortbwest of Orlo Vista, began to flow and flooded the highway

to a depth of about two feet. At the same time, some of the wells in

southeastern Orlando ceased to drain water and allowed streets to

become flAoded.

Measurements made during th3 last fourteen years show that the

water levels in Orlando and vicinity fluctuate considerably. AFctors

contributing to these fluctuations are: variations in rainfall in

areas where the formations are recharged naturally or artificially

through wells; changes in the rate of pumping from wells; and changes

in atmospheric pressure, -FltUuaxtions of the water levels in three

wells in Orange County are shown graphically in figure 4. In this

graph, measurements of water levels aro indicated by small niroles,

and the probable general trends are represented by broken lines. The

rainfall values shown on thls griph represent averages of the monthly

totals re neded at Weather Bureau Stations at'Orlando and Orlando Air

Base in Orange County, and at Lakeland, winter Haven, and Lake Alfred,.

in Polk County. These rainfall stations were selented be~ausa the

water-level flutuations in Orlando and vicinity are related to

variations in rainfall not only at Orlando but also ova the natural









recharge area whinh extends over Polk County and parts of Orange,

Highlands, and Lake Counties.

The highest stage for which water-level measurements are available

occurred in the summer of 1934, and the second highest in the summer

of 1930, The lowest stage for whi-h measurements are available

occurred in the spring of 1933, but measurements made during the

summer of 1943 indicate a stage nearly as low as that of 1933.

Automatic water-level recording instruments have been installed

on well 47, near Orlo Vista, and on wells 923 and 224 it the Orlando

Air Base. It is intended that these recorders be maintained indefinitely

to obtain continuous records of water-lnvel fluctuations.


Piozomotrin Surface


The height to which water will rise above mean sea level in

tightly cased wells penetrating the Ocala and mid-Eocene limestones

in Florida and part of Ueorgia is shown by the contour lines in

Figure 5. The imaginary surface represented by those contour lines

is called the piezometrin surface. In order to plot a map of the

piezomotric surface for a given area, measurements of the static water

levels, in feet above or below a fixed reference point, are made on

a number of wells throughout the area. The altitudes of the reference

points are determined and the water-level measurements are added to

or subtracted from these altitudes to obtain the altitude of the water

levels in the wells. These water-level altitudes are then used as

controls in plotting the contour lines representing the piezometric

surface,









As the water levels fluctuate the piezometrin surface changes

in shape and altitude, and when represented for any one time shows

only approximately the conditions for any other time. Although the

general form of the surface is constant, variations in local conditions

may cause some change in details from time to time. In general, areas

where the piezometric surface is hih are regarded as areas of recharge

and areas where it is low are regarded as areas of discharge. The

horizontal movement of the water in the aquifer is in general from

the hihi areas of the piezometric surface toward the low areas in

directions normal to the contour lines, Thus it ncn be seen from

Figure 5 that the movement of the water in Orange County is in general

toward the northeast..

The lat region of Orange County is part of a large recharge

area which extends over most of Polk County and into the lake region

of northwestern Highlands County and south-eontral Lake County.

Water-level measurements have been made in Orlando and vicinity

at various times in the past. From measurements made by Stringfield

in 1930 and 1931, and measurements made during this investigation,

maps representing the piezometrin surfaces for May 1930, August 1931,

and August 1943 have been plotted. A study of these (Figs, 6-10)

shows that the general shape of the piozometric surface is persistent,

but that it varies from time to time in altitude and in local details.

Anotable eharanteristic of the piezometric surfaces shown in Figures

7 and 9 is tle shelf-.like feature in the vicinity of Orlando. This

feature results from local recharge through the drainage wells.









The piezometric surface for August 1930 is representative of

high water levels, and its most striking feature is the mound in

southeastern Orlando. This mound is undoubtedly due to recharge through

drainage wells and lakes,

Figures 7, 8, 9, and 10 represent the piezometric surface as of

August 1931 and August 1943. Its general shape at these times was

approximately the same except that in 1931 was higher. The mound in

southeastern Orlando, so prominent in 1930, was not present in 1931

and 1943, but a anall spur in the same area indicates that the shape

of the surface is influenced by local recharge even at tim3s of low

water levels.

The Ocala and middle Eonene limestone have.bi-n separated

geologically on differences in texture, color, and fossil content.

Hydrologically, however, they appear more or less as a unit, that is,

the water levels in wells drilled into the upper part of these lime-

stones rise to the same heights as in walls drilled to deeper horizons.

In order to determine and study the relationship between the

water in upper and lower portions of the Eocene aquifer, two wells

were drilled at th3 Orlando Air Base. One of these, well 223, is

453 feet deep and is cased to 180 feet; the other, well 224, is 1,000

feet deep and is cased to 569 feet. Records from automatic water-level

recorders installed on both wells indicate that the water in the two

wells rises to the same level, and that the water levels are affected

similarly and simultaneously by the pumping of nearby walls. This

shows that the upper and lower parts of the aquifer are under equal









artesian pressure and that there is probably free vertical exchange of

the water within the aquifer.


Springs


Two large springs, whiih yield water from openings in the Haw-

thorn formation, m.ur in Orange County.

Rook Spring, about five miles north of Apopka, in the north half

of section 15, T. 20 S., R. 28 E., is one of few springs in Florida

whinh issue from an opening above the water surface. This spring

issues from a nave-like opening at the base of a 15-foot vertical

exposure of brown, phosphatio, sandy limestone, and flows into Rook

Spring Run and thenne into the Wekiva River. The discharge of the

spring is about 50 to 60 second feet.

Wekiva Spring, about three miles northeast of Apopka, in the

northeast portion of section 36, T. 20 S., P. 28 E., issues from an

opening below the water surface and flows into the W 'kiva River. The

discharge from this spring is about 65 second feet.

Sanlando Spring is smaller than either of the springs mentioned

above. It is in Seminole County, near the border between sections 2

and 3, T. 20 S., R. 29 The opening of this spring is below the water

surface, and overflow from the spring basin flows into the Little

Wekiva River.








Wells


Wells have been constructed in Orange County for two purposes:

to obtain water and to dispose of water. A few wells hqve been non-

strunted to serve both purposes, that is, they are used to obtain

water for irrigation during dry seasons and to drain surplus water

during wet seasons,


Supply Wells


With the exception of a few wells ending in the surfinial sand,

and a few drawing water from the pervious layers of the Hawthorn

formation, the supply wells of Orange County are drilled into the

c0ala and mid-Eo ene limestones. Most of the privately-owned supply

wells used to obtain water for domestic and irrigation purposes are

less then 200 faet deep. tells used for industrial or municipal

supplies range in depth from 200 to 1,000 feet.

During the present investigation emphasis was placed on the

collection of information relating to drainage and sanitary wells.

Annordingly, the Table of Well Reamrds (Table 1) an ompanying this

report contains Information nn only a few supply wells.


Drainage Wells


Annording to Sellards (1908, p. 62-63 and 1910, p. 71) and

Stringfield (1953, p. 21), the first drainage well in Orange County

was drilled about 1904. In April of that year, a sinkhole (probably

Lake Greenwood), whi^h had previously carried away surplus surface

water through its connections with underground drainage channels,








became logged, and a considerable area in southeastern Orlando was

flooded by heavy rains., After several unsurccessful attempts to reopen

the sink, a drainage well was drilled as an experiment, In August,

a two-inch test vell was drilled, and it proved suteessful enough to

warrant the construction of larger wells, The next year two more wells,

one 8-innh and one 12-innh, were completed and these drained a large

part of the flooded area. Those wells, however, were not sufficient

to drain the area completely, so in the winter of 1906 two more 12-inch

wells were onstruited, and by February 1907, a fourth 12-inch w-ll

had been completed, By the end of March 1907, the water was almost

bark to its normal level.

In the following years many wells were drilled for drainage, not

only to dispose of surplus water during storms, but also to lower and

control lake levels, and to drain lowlands rmd swamps to make additional

land suitbblo for cultivation. Sanitary wells were also constructed

to drain away the effluent from septic tanks.

The most intensive period of drainage well construction was

during the years 1926, 1927, and 1928, but such wells were still being

drilled in 1943. In August 1943 at least 182 drainage wells were in

operation in Orlando and vicinity. These may be grouped as follows':

90 Storm drainage wells, owned by the City of Orlando.

40 Storm, swamp, and lake drainage wells, owned by
Orange County.

12 Drainage wells at the Orlando Air Base.

40 Privately- and munintipally-owned .drainage wells used
for various purposes, including at least one used
to dispose of citrus parking waste.









Structural Geology


Orange County lies on the southeast slope of the Ocala uplift,

where the general dip of the Ocala and middle Eocene limestones is

southward and eastward. Structural features cannot be determined from

the altitude of the upper surface of the Ocala because this surface is

irregular owing to solution and erosion. However, the top of the

middle Eocene is more regular, and its shape, as determined from

studies of well logs, suggests that a minor structural basin exists

in the vicinity of Orlando. Other minor .structural features may exist,

but they cannot be determined until more subsurface data is obtained.


GROUND 'ATER

General Conditinns


Small supplies of vwter are obtained from shallow wells ~fding

in the surficial sand, but the water from these wolls is often colored

and is susceptible to pollution by seepage from the surface. Also,

some wells obtain moderate quantities of water from pervious layers of

the Hawthorn formation. However, the principal water-bearing forma-

tions of Orange and adjacent courtties are the Ocala and middle Eocene

limestones.

The water in the Ocala and middle Eocene limestones is under

artesian pressure, that is, when the confining beds are perforated

it will rise in the well to a level higher than the top of the water-

bearing bed. In the lowlands along the St, Johns River, in eastern

Orange Uounty and northeastern Seminole County, and around the margins









The wells used for storm and swamp drainage range in depth from

120 to 1,000 feet, and are vased to depths ranging f'om 74 to about

400 feet. They range from 5 to 18 inches in di'mater,

The range of depths to which drainage wells are drilled and

cased shows that surface water is being introduced into a considerable

thickness of Ocala and mid-E~cene limestones and into the lower portion

of the Hawthorn formation Drillers' records indicate that some of

the wells end in open cavities and that others penetrate only permeable

limestone, In either case the drained water mingles with, and becomes

part of, the ground water, and moves in the direction of the slope

of the piezometric surface. At a time when a large quantity of wat.r

is entering a well, a slight mound is created in th3 piezometric

surface in the immediate vicinity of the well so that the drained

water moves for short distances in all directions from the well.

The capacity of a drainage well is dependent upon the diameter

of the well, the permeability of the receiving formation, and the

head under which water flows into the well. The cnpacities of the

wells in Orlando and vicinity range from less than one hundred to as

much as several thousand gallons a minute. Well 50, at the southeast

edge of Lake Lawne, is reported to have a cnpnaity of 9,500 gallons a

minute (Stringfield, 1933, p.' 22),








Si S -anitary Wells


The term, sanitary well, is used to designate a well which receives

sewage or the effluent from septic tanks or sewage treatment plants,

There are at least eighteen sanitary wells in Orl-ndo end vicinity.

Seventeen of these, owned by the City of Orlando, are used to drain

septic tanks at cloven scattnred localities in the City. Records of

total depths and depths of casing are not available on 41 these wells,

but those for which rnnords are available range in depth from 231 to

863 feet, and are cased to depths ranging from 67 to nearly 400 fe3t.

The casings in these wells range from 8 to 12 inc.hes in diameter.

In addition to the seventeen wells owned by the City, another

owned by the Army receives effluent from the sewage treatment plint

of the Orlando Air Base. This well is 431 feat deep 9nd is basedd to a

depth of 183 feet with 10-inch casing.

As these sanitary wells are widely separated, and as they range

greatly in total depth and depth of easing, it is evident that septic

tank and sewage treatment effluent is boing introduced into a con-

siderable area and thickness of Ocilq and mid-Eonene limestone. A few

of the wells v ich are not deeply icsed probably introduce some effluent

into the lower part of the Hawthorn formation.








Exploration of Drainage and Sanitary Wells


One of the most frequently asked questions connerning drainage

and sanitary wells is "Where does all the water go?" The water entering

such wells mingles with, and becomes part of, the ground-water supply,

but it is desirable to know at what levels the water is being absorbed

by the underlying formations. Although drillers' records show how much

of a well' is cased and how much is uncased, no information has been

available to indicate the depths of the strata that actually absorb

drainage water and sewage effluent. To obtain such information eight

wells in the vicinity of Orlando were explored with a deep-well current

meter,


Method


The deep-well current meter used consists of a srew-propeller-

type rotor mounted, with its axis vertical, on a pointed bearing

inside a iylindrinal brass case. The upper end of the rotor axis is

an eccentric shaft ihieh touches a contact wire each time the rotor

revolves, thus opening and elosing-an electric circuit. The contact

wire is attached to a binding post which is insulated from the meter

case, The meter is enclosed in a five-foot length of three-inch pipe,

which protects it and prevents it from being carried into scverns by

the velocity of the water, The assembly is lowered into the well at the

end of a double-conductor cable.. This cable consists of steel wire

wrapped around a orje of insulated popper wire. The .cpper wire is

connected to the binding post on the contact chamber and forms one
*\. .* *.









side of the electric nirnuit; the steel wire is connected with the

three-inch pipe, whinh is in enntqnt with the ease of the meter, and

forms the other side of the 'nirnuit. The electric current is provided

by a dry-nell battery, and a headphon connected into the circuit pro-

dunes sound eash tima the rotor revolves. Water flowing through the

meter will cause the rotor to revolve at a rate proportional to the

velocity of the water,

In use, the metar assembly is lowered into a wall a few feet at

a time, and the revolutions of the rotor at the several depths are

timed with a stop wateh. The rate of revolution at the various depths

indicates approximately the relative mean velocities of water at those

depths. The interpretation of the observations is based on the ex-

pression, q = av, in which g is the quantity of water per unit of time,

a is the' ross section area of the well, and v is the mean velocity of

the water passing through the well. Throughout that portion of a well

which is lined with tight easing of the same diameter the velocity

should be the same, inasmuch as the quantity of water moving through

that portion must be the same at all depths and the crossrsecttion area

is constant. However, in the uncased portions of a well differences

in velocities nt various depths may be due either to differences in

the cross-seation area of the well or to differences in the quantity of

water moving through it.

The observed relative velocities in drainage and sanitary wells

are not as consistent as those in flowing wells because the Aurrent

meter ensemble wab designed to measure upward flow of water instead of

dowhnwrd flow, and because the fall of water from the mouth of the well

apparently produces turbulence to a considerable depth,








A progressive decrease in velocity with increasing depth indicates

that the water entering the well is being absorbed by the surrounding

formations. When a level is reached below which the velocity is non-

sistently zero, it seems reasonable to assume that the water entering

the mouth of the well is not passing below that level and must there-

fore be leaving the well and entering the formations above.


Velocity Measurements in Wolls


During this investigation, five sanitary wells (Nos. 9, 19, 80,

110, and 146c) and three drainage wolls (Nos. 91, 93, and 94) were

explored, and the results are shown graphically in,Figure 11. In this

figure nre Ehown the reported drilled deoth of each well, the reported

depth of easing,' and the velocities of the current meter plotted acnord-

ing to depth. In all cases, it was impossible to exnlore the total

drilled depth because in some wells obstructions prevented the passage

of the current meter, and in others the lower portion was apparently

filled with sediment. However, in wells 80, 93, and 94, pra.ti.ally

the entire drilled depth was explored.

teoll 9, in southeastern Orlando, at the southwest edge of Lake

Davis, receives effluent from a septic tank. This w311 is reported

to have been drilled to a depth of 811 feet and cased with 8-inch

easing to a depth of 67 feet. At the time of exploration, an obstruc-

tion was eneountere- in the well at a depth of about 610 feet so that

no volocity measurements were made below that depth, A'gradual decline

in ;'velocity was noted between depths nof 60 nd 160 feet, and below

1.60- feet the~velocity wa consistently. zero t .appears, therefore,








that the septic tank effluent entering this well is being absorbed by

the formations between altitudes of 10 feet above and 90 feet below

sea level.

Wells 19 and 146' are on the south side of South St., west of Farn

Croek, at the Jouth Street Imhoff tank of the city of Orlando. With

two other wells, they receive effluent from this tank. Well 19 is

reported to be 865 feat deep and cased to 408 feot with 8-in-h casing,

The downward flow through the easing of this well was apparently

irregular, probably due to changes in the diameter of the casing, or

to defeats in the casing resulting from norrosion. Below the bottom

of the casing, the velocity was irregular but gradually decreased to

zero between the bottom of the casing and a depth of 468 feet and

remained so through the rest of the depth explored. Thus, it seems

that this well is, introducing septic tnnk effluent into the limestone

in the interval between 325 and 400 feet beloW soa level. If the

irregularities in flow through the casing are due to defects caused by

corrosion, there may also be some effluent leaving the well above the

bottom of the casing.

Thedepth of well 146c and the depth to which it is cased are not

definitely known, but it is reported to have been drilled to about 700

feet. This well is located about 50 feet south of well 146b, and its

mouth is at a lower elevation than the mouth of that well. These two

wells are. connected by underground cavities or channels in such a way

that when well 146b is receiving large quantities of effluent well 146c

becomes filled to overflowing, and the affluent flows upward through

4t and drains through a'ditch into Fern Creek and_ thence into Lake







Gra'nwood, whiih is drained by a group of five wells. At the tinm of

exploration, this upward flow was taking place in well 146n, and the

flow measured was upward instead of downward. Howiver, from a depth

of 130 feet down to 215 feet, where an obstruction was encountered,

there was no flow. The lank of flow at this depth is believed to indi-

cate that the formations below 130 feet are not receiving effluent in

appreciable quantities.

Uell 110 is in west-central Orlando, near the intersection of

Amelia Avenue and .'estmorelnnd Drive. It is one of two wells in this

locality used to drain a septic tank located beneath Amelia Avenue. This

well is 500 feet deep and is cased to a depth of 131 feet with 12-inch

casing, Below the bottom of the casing, the velocity of downward flow

varied greatly, probably due to variations in the diameter of the well.

However, it became zero at a depth of 165 feet and remained so through

the rest of the explored depth,. indicating that the effluent introduced

into the well is entering the formations in the interval between 25

and 60 feet below sea level.

Well 80 is on the north edge of a small lake northwest of the

'Orlando Air Base Sewage Treatment Plant, and receives effluent from

this plant. It is 431 feet deep, 10 inches in diameter, and eased to

a depth of 183 feet. No progressive decrease in velocity was noted in

this well, Instead, the rotor of the meter continued to revolve

throughout the explored depth and varied through a wide range near the

bottom. Accordingly, it. is probable that the entire uncased portion of

this well is introducing sewage plant effluent into a 825-foot thickness

of Oeala and mi dle iEoneeto imstone between 75 and 300 feet below sea

1evo;




29


Well 91 is at the Orlando Air Base, in the east side of A Avenue

at the intersection of Sixth Street. It is 800 feet deep, and the 6-inch

easing extends to a depth somewhere between 150 and 180 feet. This well

is used for general drainage of streets and storm run-off. The veln.ities

observed within the casing of the well were mu.h more irregular than in

other wells. This may have been due to the fast that the diameter of

the sasing was only slightly larger than that of the meter tube, so

that changes in the position.of the meter assembly may have caused the

flow to be more irregular or turbulent. An obstruction was encountered

at a depth of 312 feet, and some flow was indicated at this delth.

Hence, the lower limit of the downw-rd movement of the water is below

the depth of 312 feet, which is 215 feet below se. level.

Well 92, also at the Orlando Air Base, is at the northwest corner

of A and First Avenues, about 250 feet south-southwest of well 91. Like

well 91, this well receives general street drainage and storm run-off.

It is reported to hnve been drilled to a depth of 350 feet 'nd is

cased with 12-inch casing. The depth of the easing is not kno.n, but

changes in velocity observed during the exploration suggest that it

is about 175 feet, Below 175 feet, the velocities observed were

irregular, and no zone of zero velocity was found in the explored portion

*of the well. As an obstruction was encountered at 319 feet, the lower

limit of flow in this well is not. known.

Well 94 is on the.northwest edge of a snill lake, north of the

Qrlando Air Dase Laundry. VWste water from the laundry is emptied

into the lake, which in tura overflows into the well. This well is

482 feet deep and is cased for 221 feet with 8-inch casing. Exploration








revealed a progressive decrease in velocity from a depth of 200 feet

to 390 feet, below which it remained at zero. Seemingly, therefore,

this well is introducing laundry waste into the surrounding formations

through an interval between the altitudes of.100 and 275 feet below

sea level.


Possibility of Pollution


The possibility of pollution of the ground-water supply by the

use of drainage wells has been mentioned by Sellards (1908, pp. 64-67,

and 1910, p. 169) and Stringfield (1933, pp. 22-23).

In regions underlain by porous or cavernous limestone, the use

of sinkholes or drainage wells to dispose of sewage or surplus surface

water constitutes a threat to supply wells drawing water from the

limestone. Water which drains from roadside ditches or street gutters,

and especially that discharged from septi. tanks, is almost certain

to be polluted, and the freedom of circulation alloed by cavernous

limestones may permit such waters to enter supply wells without being

subjected to filtration, This threat is especially great for wells

located down the slope of the piezometric surface from the drainage wells.

Recent outbreaks of typhoid Fever and gastro-enteritis have

resulted from pollution of private and municipal water supplies in

Fillmore and Olmstead Counties, Minnosota. The pollution of these

supplies was traced to sinkholes and stone quarries through which

partly treated sewage and excreta were being introduced into the

limestone aquifer which yielded water to ths supply wells (Kingston,









1943), Several rcses of pollution In Orange County, seemingly due to

drainage wells, have been reported but are not supported by fartul

data,

The purpose of this investigation has been to obtain geologic

and hydrologic information relating to the possibilities of pollution.

Further chemical and ba^teriological investigations are desirable, and

it is expected that the State Board of Health will make such studies.

There has been a somewhat prevalent idea that all the drainage

wells in Orange County were relatively shallow nnd that therefore deeper

wells should be safe from pollution. Data herewith presented indicate

that drainage wells as deep as 1,000 feet, and sanitary wells exceeding

850 feet, are in use. The depth of casing in these wells ranges from

67 to 400 feet, Exploration of several wells indicates that water

from them is entering the surrounding formations at depths ranging from

70 to at least 400 feet, and that in the deeper wells it may go to

greater depths.

Geologin studies hnve indicted that the formations penetrated by

the drainage wells are porous and contain ramifying solution channels.

The interconnected pores and solution thannals allow free circulation

of the water. Equal artesian pressures in the lower and upper portions

of the aquifer will permit interchange of water batwemn the upper and

lower parts of the formation. The general horizontal direction in which

this water moves after entering the aquifer is determined by the shape

of the piezometric surface.

The piezometric surface in Orange County has a general northeast-

ward slope. However, the ioncentration of drainage wells in and around










Orlando appears to contributee to the res-hrge in sufficient quantities

to niuse a lonal flattening of this surface, and at timos of heavy

rainfall, aresat a small mound in it in southeastern Orlando. Within

the flattened area of the piezometri. surface, there is pronbbly free

intermingling of the drainage water with the ground water, and from

this area the water moves down the slope of the piezometrie surf ae.

Therefore, it seems thet the areas most susceptible to pollution qar

those surrounding the wells, and adjacent areas down the slope of the

piezometri" surface. VWells drilled in the regions up the piezometrie

slope from the areis in whiih drainage and snlitary Jwells re concen-

trated should be relatively froe from pollution.
