with the environment and be of maximum benefit to the publ ic. Some
sort of authority or regulatory agency operating under rules and regu-
lations is needed to insure that development of the water resources
fits the environmental conditions and is in the public interest.
In Florida, like most of the nation, population was relatively
sparse and cities were relatively small during the early years of
water resource development. Domestic and industrial water needs
were small; irrigation of crops in Florida was essentially non-existent.
Under these conditions the development of a water supply, such as from
a well for a household, was an individual matter. The success or
failure of such individual act-ions was essentially the concern only
of the particular developer. The effects of development were hardly
noticed by others.
However, present water demands by cities, industries, agriculture,
and others are large, and .a-ch development has an effect upon the other.
Uncoordinated development without order may lead to chaos; it is
competitive, promiscuous, and ruinous. Without overall planning,
certain detrimental effects occur or will occur. Some of the detri-
.-"aTT2 (w.t,.. elor. uncoo.rd i nated develop-
ment of water are: inordinate reduction of supply, deterioration of
supply, excessive lowering or drying of lakes, and significant decrease
in flow of springs and streams. Other possible effects are pollution
of waters by surface and underground disposal of wastes and encroach-
ment by salt water.
Inordinate reduction of supply results when wells of large
capacity are closely spaced and the total pumpage taxes the ability
of the aquifer system to supply the water. As a result, water levels
in the aquifer system lower to such an extent that the yields of the
wells are significantly reduced.
Deterioration of supply results when inferior water moves to wells.
This is brought about by a number of interrelated situations. First,
inferior water may move upward from depth to the wells because of
excessive pumping and consequent uncurbed lowering of water levels.
Second, inferior water may move into fresh-water aquifers by wells
drilled overly deep into salt water or by wells that are poorly or
inadequately cased. Third, inferior water may migrate laterally to
wells due to inadequate control of surficial canals or to locating
pfwells too close to the coast.
Excessive lowering of lakes and significant decrease in flow of
springs and streams result when wells of significant capacity are
located so that pumping inordinately affects a lake, stream, or spring.
Pollution of ground waters results from injecting wastes into
fresh-water aquifers. This can be done by means of wells finished
In a fresh-water aquifer or by infiltration to the fresh-water aquifer
of liquid and .solid wases from disposal sites. Waste disposal wells
completed at dei into oor qua) mty water may also pollute fresh
H waters if not properly cased or if the geologic and hydrologic con-
ditions are such that the fresh and salt-water systems are interconnected.
Encroachment of salt water results from lowering of water levels
by wells, as mentioned above, and from construction of canals and
drains so that salt water moves inland through the aquifer system.
Detrimental effects mentioned can be mitigated by coordinated
development tailored to the geologic and hydrologic conditions and to
the existing and planned development of the particular area. Simply,
the depth, construction, location, and rate of extraction of water
from wells, and the location and construction of drains and canals
are key elements in effectuating efficient use of our water resources.
The fact that such detrimental effects as yet are not widespread
in Florida is due to Florida's good fortune in having a naturally
abundant supply of water. Because of burgeoning population in Florida,
particularly as exemplified in the west-central part, the side effects
of the many individual and uncoordinated water developments may
potentially inflict costly and irreparable harm on the water resources
of the area. Rules and regulations are the guideposts of civilization.
Conservation of natural resources with due regard to physical laws
I Water is a dynamic resource, being continually renewed by nature
and continually depleted by man. Further, both the natural environ-
S:mental i' t orRf-atd-the -vej" e nts by man are not uniform every-
"where. Rules and regulations promulgated to conserve and promote
wise and effective development and management of water and land resources
thus must be flexible and tailored to particular areas and situations.
The proposed rules and regulations of the Southwest Florida
Water Managment District (Regulatory) for the development, control,
conservation and use of water resources, with particular reference to
ground water, are a step in the direction of bringing about coordinated
development that will be compatible with the hydrologic and geologic
environment and will promote conservation of the resource to the
benefit of all.
The proposed rules and regulations are flexible and provide a
means by which decisions as to well construction, such as depths and
casing, and well location, can be tailored to the particular environ-
ment through the mechanism of applications to drill and the issuance
of permits. The rules and regulations provide for maintaining current
knowledge of water developments and water use as deemed necessary.
This is an aspect of water resource accounting and evaluation by
which decision as to current and potential adequacy of supply may
be based, The regulatiOns should not only conserve and protect the
water resources bat also should promote beneficial use.
