The day when Acti-Aid will be
widely used to harvest citrus fruit is
near But you can start getting ready
for Acti-Aid today...and enjoy its
many benefits while you're at it.
Acti-Aid is an abscission agent
that loosens fruit by reducing the pull
force required to remove fruit from
the stem from 15 pounds down to

as little as 3. That can increase your
current hand harvesting efficiency
by an average of 57% according
to research trials.
By gaining experience now with
Acti-Aid on various blocks, you'll
be laying the ground work for future
full scale use with hand or mechan-
ical harvesting.

So contact your Acti-Aid
distributor. Asgrow Florida Com-
pany, today Try Acti-Aid on a few
blocks this year. Youll be ready
for the years to come.

20-foot contour of water to move
inland into southwestern Hardee
County-a distance of 54 miles.
Water tables have been depressed
during the dry season by as much
as 70 feet south of Bartow and
However, Parker adds, this in-
land depression is caused by other
withdrawals besides agricultural
uses. This large depressed area has
been caused by the removal of
some 350 MGD (million gallons a
day) for phosphate mining and ore
processing, 250 MGD for agri-
cultural irrigation and fruit pro-
cessing, and another 50 MGD for
all other uses, chiefly municipal.
This adds up to 650 MGD- more
than six times as much water as is
used in the Tampa-St. Petersburg
metropolitan areas.
"Although the U.S. Geological
Survey has not completed its test-
ing program, we know the water
quality in many wells within 40
miles of the coast is deteriorating.
A larger number of wells have
become salty in just the past year.
Salt-water encroachment is taking
place, and it's moving inland. For
example, wells along the coast in
Pasco County are now yielding salt
water, and the city of New Port
Richey recently lost its well field
because of salt water intrusion.
Years ago, Tampa and St. Peters-
burg lost their downtown well
fields in the same manner," Parker
The location and design of large
well fields for the cities of Tampa
and St. Petersburg have aggravated
the drawdown problem in Hills-
borough and Pasco counties, he
explains. Ths four major well fields
that supply Pinellas County and
St. Petersburg are so close to one
another that they actually rob one
another of their water supply.
"The problem with these big well
fields is that they were not de-
signed to account for the cone of
depression that develops around
each of them. Water levels may
drop by as much as 35 feet in the
center of each well field, and each
cone of depression overlaps the
others, producing one huge cone
that extends outward for many
miles. Water levels have been de-
pressed over a wide area, and

Water use restrictions-includ-
ing the use of flow meters-may
be needed in the future to protect
big agricultural and industrial users
from ruining their own water
supply, says one of the nation's
leading water resource experts.
Garald G. Parker, consultant
with P.E. LaMoreaux & Associates,
Inc., Tampa, and former president
of the American Water Resources
Association, believes that Florida
has plenty of water for the future if
it isn't wasted.
But, even with no waste, the big
problem in the years ahead will be
the high costs of getting water into
the rapidly expanding, high-use
urban areas along the coast where
water tables are already dropping
and the danger of salt-water intru-
sion looms ever larger, he says.
Parker, former chief hydrologist
with the Southwest Florida Water
Management District (SWFWMD),
Brooksville, points out that energy
costs for pumping water from ever-
greater depths or distances for
agricultural irrigation may eventu-
ally outweigh any possible profits
from crops. The problem is poten-
tially most serious in the coastal
areas of SWFWMD, especially
south and southwest of the Tampa
Bay area. SWFWMD includes 15
counties extending from Levy and
Marion counties on the north to
Charlotte County on the south.
He cited studies by the U.S.
Geological Survey which indicate
the line of contact between salt
water and fresh water is moving
inland from the coast. Water levels
in the artesian aquifer along the
coast were 20 feet above sea level
in 1964, but heavy pumping during
irrigation seasons has caused that

plants either die or show signs of
severe stress because they are un-
able to send roots down fast
enough to cope with the change,"
Parker says.
Regarding the recently deve-
loped area of drawdown in the
interior of SWFWMD, the water
resources expert believes that large
quantities of water can be safely
drawn in southern Polk and eastern
Hillsborough for the next 20 or 30
"Even though water tables in


this inland area may be lowered
near sea level, such as we experi-
enced during the 1975 irrigation
season in the area south of Bartow,
the hindrances to salt-water intru-
sion in that area are great. It will
take a long time for salt water to
break through. I believe we can
continue pumping at present rates
for a number of years yet, but we
are going to have to watch it care-
fully. If salt water does break
through, then we will have to dras-
tically reduce water use or bring
about a greater amount of artificial


recharge," Parker states. I
He says vast amounts of water
could be saved if growers and
ranchers would adopt less wasteful
irrigation practices. Hundreds of
abandoned irrigation wells were
also cited as a big source of waste.
"The problem, as I see it, is that
many growers in Manatee, Sara-
sota and southern Hillsborough
counties have been careless in
their use of irrigation water. In-
stead of using only what crops
require, many growers keep the
ditches between the furrows full of
water, allowing vast quantities of
water to escape into roadside
ditches, which eventually dis-
charge into the Gulf of Mexico.
This is obviously a very great waste
of water," Parker asserts.
"Another source of waste in-
volves hundreds of old wells scat-
tered all along the coastal areas of
SWFWMD, particularly in the zone
south of Tampa. When water from
these wells became salty years ago,
many growers simply moved in-
land and abandoned the wells. As
a result, there are some 1,000 old
wells that are still flowing-run-
ning night and day, wasting water
like crazy," Parker says.
Many of these wells are in areas
that are now highly urban. These
abandoned wells need to be
plugged, but many urban land
owners are unwilling to pay the
high cost of plugging. Because of
this, he explains, the SWFWMD is
now beginning to tackle the prob-
lem itself, plugging wells with con-
crete from the bottom up. But this
is a slow and costly project, requir-
ing years of work.
On the complex question of
water rationing for the future, Par-
ker says it may eventually be
necessary to establish some sort of
hazard line along the coast and
limit the amount of water that can
be pumped in areas coastwardd"
of that line.
"Decisions of this kind involve
people and politics. Politicians are
not likely to cut off someone's
water because there is a chance
pumping might cause salt-water
intrusion. It may eventually be
necessary to establish some limits
on the depth from which water
can be pumped as well as the
amount of water that can be drawn
from a particular area," Parker
