Scientific knowledge is meaningless unless it is widely disseminated and becomes common knowledge among the
public. The public needs to become aware in order to become involved in restoration activity. Man has upset the natural
balance of the ecosystem and must be engaged in restoring the balance. Sustainable use of water resources cannot be
achieved unless resource users agree on basic principles in resource stability and availability - in the past, in the
present and in the future, with due protection and conservation measures collectively introduced.
It is futile to make judgments on the sustainability of water resources without scientific knowledge in regard to
possible natural and anthropogenic variances. A scientifically well-informed decision is important, not because the
decision will always be correct, but, because the decision can be assessed scientifically and updated to reflect new
scientific findings over time. That is the true worth of science, and a process incorporated in Adaptive Management.
Over 30 years ago, Edward S. Deevey, Jr., delivered a statement to the National Water Commission entitled “In
Defense of Mud.” Deevey, a distinguished limnologist (one who studies inland waters) argued that mudThe habitat for essential micro-organisms, is as important as water to the health of this planet. Edward S Deevey Jr,

all have different kinds of mud and associated microorganisms.
Deevey expressed his concerns with, "a common yet dangerous misapprehension: the idea that balanced living
systems consist of animals plus plants. As long as the sun shines and the plants are green, it seems to follow that
animals and people have nothing to worry about. The truth, of course, is that no living system is ever balanced without
microbes" (1970). Microorganisms that live only in mud produce hydrogenase, a catalyst for recycling
natural materials. Hydrogenase breaks down nitrogen and sulfur in dead matter to forms that can be used by plants to
grow new tissueA group of similar cells that are organized into a structure with a specific purpose.. These microorganisms also help reduce
pollution by breaking down harmful compoundA compound is the atoms of different elements joined together. and contributing
oxygen to the atmosphere. Hydrogenase producing microorganisms are found in the mud of lakes, swamps, marshes and

conservationists, the haunts of coot and heron seemed to need no reasoned defense from anybody. Henceforth, I believe,
the ‘new conservation’ can take a more worldly stand. Its basis is that hydrogenase, like water and oxygen,
is no longer a ‘free good’, but a commodity more precious than we know” (1970).
Florida once had extensive and highly productive ecosystemsa community of organisms, including humans, interacting with one another and the environment in which they live.,
many of which were altered and degraded by urban and agricultural development. Much of the activity resulted from a lack
of knowledge concerning how ecosystemsa community of organisms, including humans, interacting with one another and the environment in which they live. function, how they
are interrelated and the ways in which they help sustain people. There is currently a need to restore the function and
integrity of what remains.
We cannot return to what used to be, but we can restore, protect and more effectively manage what we have. Sound
science needs to be the foundation, and communication, education and public involvement, the cornerstones.
Many things can be taken apart, but some, such as biological systems, are very difficult to put back together again.
On the surface, a biological system may look like it’s “fixed”, but it might not work. Some parts may
be missing, some may be forgotten or some may not be put back in the proper relationship to other parts. Complexity and
diversity tend to be hallmarks of unaltered systems, and this makes restoration very difficult. Like a broken eggshell,

Threats to Florida's Springs
We can but reflect upon the threats to a most cherished resource of North Florida - fresh water springs - to
exemplify need for concern. Too many of us fail to appreciate just how much we do things which adversely impact the
things we treasure most. Sometimes it is because we do not think what we do as an individual could possibly affect
issues which are simply beyond our understanding. Consider the following issues, for example:
Landscaping and Lawn Care
How can what we do to our tiny yard possibly have any impact? The collective impact on water qualityA term used to describe the chemical, physical, and biological characteristics of water, usually in respect to its suitability for a particular purpose. of several million yards is considerable indeed. Our choice of grass, whether we over dose with chemical
fertilizers, or herbicides to control weeds, has a significant impact on both the quality and quantity of water in the
aquifer. When we thus blindly contribute to high levels of nitratesForm of nitrogen commonly found in the soil and used by plants for building amino acids, DNA and proteins. It is commonly produced by the chemical modification of nitrite by specialized bacteria. Chemical formula for nitrate is NO3-.
in the aquifer, our source of drinking water, these nitrates in the water contribute to nuisance algae growth affecting
health and can endanger fragile plants and wildlife speciesA taxonomic category subordinate to a genus (or subgenus) and superior to a subspecies or variety, composed of individuals possessing common characters distinguishing them from other categories of individuals of the same taxonomic level.

to keep them healthy and disease-free. Nearly fifty percent of all water withdrawn for public supply is used solely to
water residential lawns and landscaping.
Sprawl and Development
Rarely do we think ourselves responsible for sprawl and development. We just live and enjoy where we live. Others
cause sprawl and so called development. Florida's rapid increase in population since 1950 has led to dramatic
changes in land use, transforming rural areas that were once dominated by forests and native grasslands into residential
developments, shopping centers, and industrial parks. The increase in pavement, roads, and other imperviousNot allowing fluid to pass through
surfaces associated with development prevents rainwater from percolating into the aquifer and increases runoffThe topographic flow of water from precipitation to stream channels located at lower elevations.

demand can result in diminished water flow at the springs and harm to sensitive plants and animals. The negative
downstream impact can also be quite significant for rivers like the Crystal and Chassahowiska Rivers that are supported
by the springs' flow.
Runoff and Stormwater
Stormwater run-off and pollution represents one of the most serious threats to the health of Florida's
groundwater and springs, which should be taken care of corporately by the communities we live in. As voters and the
concerned we have a duty to add to the strength of the corporate voice to ensure our city and county officials do take
that care. As stormwater flows off of highways, county roads, parking lots, and residential developments, it carries

quality and the springs.
Water Consumption and Overuse
How easy it is for us to fall into the fool's belief that Florida's water supply is unending when we are
caught in a summer storm. Florida's abundance of aquatic environments does not mean that we have water to spare.
Every day, over four billion gallons of groundwater are consumed to satisfy the demands of agriculture, industry, power
plants, development, and municipal and public water supplies, and as a result, we are depleting our natural, underground
water resources faster than they can be replenished. Excess groundwater use does not simply mean we may one day run out
of water, however. It also has a direct, negative impact on the biological communities of the springs as well as
possibly leading to the collapse of the underground geologic structures and the formation of more sinkholes.
Although creative new ways of conserving water are being instituted , at many springs water flow levels have been
dramatically reduced. For example, flow at Blue Spring in Volusia County, has decreased significantly thereby reducing
critical habitatThe place or set of environmental conditions in which a particular organism lives. for more than 100 manatees that visit the
spring each winter. Kissengen Spring in Polk County was once a popular swimming area and place for recreation. By the
1950s, pumping of water in the spring recharge area caused the spring to dry up.
Being dumb headed can do great harm. Throughout the state sinkholes have been targets for illegal dumping for many
years. Yet, sinkholes don't make trash go away. Instead, dangerous refuse such as lead-acid batteries, oil filters,
household chemicals, and construction materials are introduced directly into the aquifer, our water supply and springs.
Illegal dumping into sinkholes can also have a negative impact on plants and animals in the springs. Sinkholes located
in urban areas or close to roads and parking lots are particularly vulnerable to illegal dumping. In 1998, volunteers
removed more than a one and a half tons of debris from Columbia County's Rose Sink alone.
Row Crop Agriculture
Even striving for efficiency and increased profits can have a negative effect. Row-crop agriculture is a $5.5 billion
dollar business in Florida and yet impairs both quality and quantity of Florida's groundwaterWater in the ground. Water that occupies the pore spaces found in some types of bedrock..
Every year, millions of tons of fertilizers and pesticidesA chemical that kills, controls, drives away, or modifies the behavior of pests.
are applied to fields to improve crop yields, kill insects and prevent disease. Unfortunately, excess quantities of
these pesticides and fertilizers leach directly underground or enter the aquifer through sinkholes and surface rivers.
Like chemicals used in residential landscaping, agricultural fertilizers and pesticides can pollute our drinking water
and harm sensitive biological communities at the springs. Row-crop agriculture is also Florida's second largest
consumer of groundwater, accounting for significant percentage of the more than 1.5 billion gallons withdrawn from the
aquifer for agriculture each day. Thinking outside the box should reduce the quantity of agricultural chemicals applied
and add to the bottom line.
Florida's dairy and livestock industry is one of the largest in the country, occupying over 700,000 acres of land.
However, livestock farms can have a significant impact on both the quality and quantity of the water stored in Florida's
aquifer. Each year, over 400,000 tons of animal wastes enter our groundwater through surface streams, sinkholes, and
through direct infiltration into the soil. Weeks, months, and sometimes even years later, these contaminantsSomething that contaminates.
end up in our drinking water and in the springs themselves where they can harm sensitive underwater plant and

The quality of the returned water may not be the same as when it was originally removed. Compare with water consumption. for irrigation.
For a golfer this is difficult to write. Over fifteen hundred golf courses exist in Florida, more than any other
state in the country, and the number continues to grow each year. Like other conversion of natural open spaces, golf
courses can also harm Florida's aquifers, altering traditional, rural land uses within spring recharge basins as
well as increasing nutrient loads and water withdrawals. Fairways, tees, and greens require specialized varieties of
grass, like Bermuda grass, that are regularly fertilized. If applied improperly, fertilizers can leach past the root
systems and soil, and eventually infiltrate the aquifer. In many areas of Florida, golf courses are also associated with
residential "country club" communities that introduce additional threats to the springs by increasing
residential landscaping, household water use, and direct recreational impacts.
Springs recreation and attractions are a multi-million dollar industry in north Florida. In 1999 alone, more than two
million people visited the twelve state parks named for springs, contributing over $7 million in revenue. Yet, due to
their immense popularity as locations for camping, swimming, tubing, diving, and canoeing, some springs are being "loved
to death". During the peak summer months, Ichetucknee Springs State Park's daily limit of 750 tubers on the
upper river can be reached within an hour after the park opens. Such concentrated human use can have a direct impact on
the springs as well as the animals and plants that live there. Tubers and swimmers can unknowingly trample native
