at this time concerning seasonal rainfall and water table elevation extremes
and characteristics, levels cannot be assigned at this time. A letter dated
April 3, 1974 from Mr. Craig Hutchinson, Hydrologist with the U.S. Geological
Survey in Tampa, to Mr. Rod Cherry, Director of the Water Resources Division,
SWFWMD, along with attached maps indicating the water table and potentiometric
surface configurations was entered as Exhibit 1. The staff recommended that
the Board defer establishing regulatory monitor levels for the shallow aquifer
until its meeting in September. Concern was expressed that a delay until
September might impose difficulties in timing since the wording in the docu-
ment calls for the levels to be effective by October 1. After discussion the
Board took the following action. ^ 'ti on was made 'y Mr. Vauihn that: regu,

tonrJed b, ;r. Grw. and passed unanii;;ouslyzf Motion was mniade by Mr. Vaughn,
seconded' by Mr.. Graw, that-the-action on the shallow well monitoring system
for the Section 21, Cosme-Odessa and South Pasco Well Fields be deferred until
an August hearing to take place during the Board's normal meeting and with the
understanding that if adequate data is not available at that time the hearing
will be continued until the Board's September meeting. Motion unanimously
passed. Mr. Blain stated that both of these actions will be embraced in
Order 74-2R, amending Order 73-6R, to be drafted as soon as possible. This
Order will be made a part of these minutes as if set out herein in full, but
for convenience sake will be filed in the permanent orders file of the District.
Motion was then made by Mr. Vaughn, seconded by Mr. Hill, that the public
hearing be terminated. Motion unanimously carried.

Mr. Carl Linn, Attorney for the City of St. Petersburg, commented upon the
current status of the Cypress Creek Well Field. He expressed concern over
the fact that land acquisition is approximately two months behind schedule.
Mr. Pick Talley of Pinellas County also expressed concern on behalf of the
County over the delay in land acquisition. Mr. Blain stated that the problem
has stemmed from the fact that the District has no authority for an order of
quick taking except for flood control purposes and then only if the District
is ready to begin construction immediately, which the District is not in a
position to do at this time. He stated that in the meantime he has been urging
the City of St. Petersburg, Pinellas and Pasco Counties to adopt the necessary
resolutions that would provide the justifications and time schedules that would
allow the District to proceed toward obtaining orders of quick taking based
upon the authority the counties and city have once the necessity has been estab-
lished by the resolutions.

At this point the meeting was recessed.for lunch. Following the recess Chair-
man McAteer presented


explaining that in making these three rivers "Works of the District" the Dis-
trict is provided with the capability of preventing further degradation of the
rivers as valuable resources. The staff recommends approval. Motion was made
by Mr. Vaughn, seconded by Mr. Graw, that Resolution No. 542 be approved.
Motion passed unanimously. This resolution is made a part of these minutes as
if set out herein in full, but for convenience sake is filed in the permanent
resolution files of the District.

Motion was made by Mr. Vaughn, seconded by Mr. Beville that the applications
submitted by Mlr. Benton Mlurphey for well permits outside the Water Shortage
Area be removed from the table. Motion passed with Chairman McAteer, Mr.
Anderson and Mr. Graw voting "no". The background data on these permit
applications for ten 16-inch wells with an estimated production capacity of
2,300 gpm, per well was reviewed by the Board. Mr. Murphey offered his com-
ments with regard to the applications. It was the general consensus of the
Board that sufficient information has not been furnished by Mr. Murphey as to
the proposed usage of the water to be produced. After a full discussion it
was moved by Mr. Vaughn that the permit applications be denied. Motion sec-
onded by Mr. Anderson and unanimously approved.

and distribution of photogrammetric aerial mapping which provides for making
them available to private individuals at a cost of $25 per sheet and free of
charge to governmental agencies. This photogrammetric mapping has a scale of
1" = 200 ft. and 1" = 400 ft. Since the adoption of this policy, aerial
mosaics have become available that are based on a scale of 1" = 1,000 ft.
with 2 ft. contour intervals. These mosaics are now being purchased in addi-
tion to the photogrammetric mapping. The staff is requesting that a policy
fo.r the sale and distribution of these mosaic sheets be established. After
considerable discussion motion was made by Mr. Vaughn that the photogrammetrico
aerial mapping as well as the mosaic sheets be sold to private individuals for
$10 per sheet and furnished free of charge to governmental agencies. Motion
seconded by Mr. Van der Veer and unanimously approved.
Mr. Blain reported on the status of legislative action as follows:
1. He stated that Representative Spicola has introduced a bill which would
give all water management districts certain water production responsi-
bilities. One section of this bill contains a provision which states
that the water management districts would have the authority to exercise
the power of eminent domain to acquire municipally owned well fields
located outside the municipality and county owned well-fields located
outside the county. A companion bill has also been introduced by Senator
Lane in the Senate.
2. With regard to changes to the fiscal year, a bill has been introduced
by Representative Ogden which would give the District the authority to
adopt either a 15-month fiscal period or a 12-month and 3-month fiscal
period in order to allow transition into the October 1 fiscal year. Mr.
Blain stated that he hopes this bill will pass very early in the session.

3. Mr. Anderson questioned the status of the bill mentioned last month re-
garding the creation of a drainage district in Hillsborough County. Mr.
Blain replied that this is a local bill and he believes the sponsors of
the bill will have no objection to including in that bill the same pro-
visions contained in Chapter 298 of the Florida Statutes which gives the
water management districts the opportunity for input prior to the estab-
lishment of any additional drainage districts.
4. Mr. Graw asked Mr. Blain if he had heard any discussion as to the Flood
Protection Disaster Act of 1973 in connection with floodplain zoning. Mr.
Blain said there is serious concern on the part of those reviewing the
federal act and its provisions for regulation of construction within the
100-year flood. He said he had not heard it discussed in relation to
the State's floodplain zoning act.
Mr. Vaughn commented that Mr. Blain has secured several rooms in Tallahassee
for use as office space. Mr. Blain explained that Capitol Services has actually
rented this office space and it is available for use by District personnel. Mr.
Vaughn suggested that the District appropriate funds for equipping this office
for use by the District. After a full discussion motion was made by Mr. Vaughn
that $300 be authorized for expenditure by Mr. Blain for the purchase of files,
equipment or whatever might be needed for the office on behalf of the District
and for specific use by the District. Motion seconded by Mr. Beville and passed

Mr. McAteer arrived at the meeting at this time and assumed the Chair. Follow-
ing a short recess the meeting was declared a public hearing at precisely 11:00
a.m. with regard to Regulatory Order 73-6R issued to the City of St. Petersburg.
Formal notification of the public hearing was accepted on behalf of the City by
Mr. Duynslager at the March 13 Governing Board meeting. The hearing was mechan-
ically recorded and the tapes of the proceedings will be available in the Dis-
trict files. The two issues to be considered during the hearing are: (1) the
status of the regulatory monitor well, E-100, located in the Cosme-Odessa Well
Field; and (2) establishing of regulatory monitor levels for the shallow aquifer
of the City's Section 21, Cosmie-Odessa and South Pasco Well Fields. With regard
to the E-100 well, the staff recommends the following: (1) that E-100 be modi-
fied by the City of St. Petersburg before April 1, 1975 to provide a valid salt-
water encroachment monitor well; (2) that Wel No. 3 at coordinates 280607N-
0823530W be designated as a regulatory well and the regulatory level of 20 ft.
above msl be adopted; and (3) that a totalizing flow meter be installed on
production Well No. 3A (280607N-0823528W). In connection with the establish-
ment of regulatory levels for the shallow aquifers of the City's well fields,
Mr. Smith of the District staff reported that because insufficient data exists

Relative to E-100, the staff must approve the plans for correcting E-100
whenever St. Petersburg's consultant submits them to us. The plans must
be approved in writing and the corrective measures completed by April 1975.


It was determined that regulatory well E-100 was inefficient as a chloride
monitor well. Grace 3 has been accepted by the Governing Board as a replace-
ment but the official notice is delayed in legal paper work. Consequently,
E-100 is still being used as a regulatory well. Approval of the corrective
nmasures for E-100 and reading tne regulatory well are the only future staff
responsibilities at this tine."

L. Using a total of 12 mwjd withdrawal, equally distributed over the
entire well field, the drawdon In Grace 3 was calculated to oe 8.05
feet. Using tve June 1973 potentionetric surface maps issued periodically
since June 1971 by the U. S. Geological Survey, a potentioretric level
was interpreted to be 28 feet at Grace 3, assum-.ing thie well field was
not in existence, This allowed for the low water period of the
year and natural and surrounding effects on the water level. Therefore,
28 feet minus 38.05 feet of drawdown equals a regulatory level of 19.95 feet
above imean sea level, .

II, Using 640,000 gpd/jni2 as the allowable water crop, the generally accepted
regional transiiissivity equal to 400,000 gpd/ft, (also deterridned by the
City of St. Petersourg's consultant of Legett, Brashears and Graham from
the well field's 1949 putiop test data) and a staff's value for leaKance
equal to 1.25 x 10-- gpd/ft.l3 (no leakance value was determined from the
pump test data due to a lack of data), a h.ad difference of 19 feet would
be required to pass the water crop at the well field boundary. Again using
1973 water level maps, tne potentiometric surface was interpolated to be
28 feet and the water table was interpolated to be 3) feet. This indicates
a natural head difference of 11 feet or an allowable drawdown of eight
feet at the well field boundary. With these constraints the drawdown in
Grace 3 was computed to be 10.05 feet or a regulatory level of 17.95 fcet
above ican sea level. The City of St. Petersburg's consultant was conducting
an independent study of the problem during this sarm tire. Tneir recom;1nded
regulatory level was 20.0 feet above risl. Due to the flexibility of leak-
ance values, tne lack of data, and the closeness of our figures we agreed
that 20.0 feet above msl was a reasonable regulatory level.


On April 19, 1974 the staff's recommendation to replace E-100 with the
number 3 well as a regulatory well was presented to thie Governing Board
and accepted by them. Tie naihe Grace 3 was later proposed and accepted .
as thie official name for the number 3 well. At the same meeting, St. Peters-
burg was ordered to begin procedures for making E-100 a valid chloride
monitor well within one year.

As of this writing E-100 is still being used as regulatory well although
Grace 3 has been equipped witn a recorder. Grace 3 has not been considered
tile regulatory well because official notice hias not been issued to the staff.
It appears that tne conversion is being delayed in Tallahiassee.

As with all other regulatory wells thie staff has assumed the responsibility
of reading Grace 3 wienever It is legally declared thle regulatory well.

To determine the validity of the well as a monitor, the foll wing sets
of data were analyzed:

A. Well inventory within four surrounding square miles.
B. Lateral distances to major irrigation wells and their drawdown
effects on E-100.
C. Chloride data for all "E" series wells.
"D. Chloride values relative to time. : **- -
E. Chloride level changes at various depths.
F. Chloride values relative to puripage rates and production
well location.
G. Chloride values and trends relative to water levels.
H. Past conductivity and temperature lons of the well.
I. Conductivity, temperature, and flow logs done by the U. S. Geological
Survey at our request on February 21, 1973.
J. Strategraphic log of the well.
K. The vells construction.
L. Pur;page records compared to water level trends.
MO. Delay tirxA from close production wells. -. lb : o

The results of this analysis indicated that E-100 did not give expected
results. The present state of well construction was the greatest factor
effecting the validity of E-100 as a chloride monitor well. It was decided
that E-100 should have corrective construction or be replaced to provide .
accurate monitoring of the chloride levels.

In order to maintain monitoring in this area of the well field two nearby
abandoned production wells were considered as replacement regulatory wells.
The use of an abandoned production well would allow tne monitoring of the
production zone and create consistency in our regulatory .ethiods.
Recorders were placed on both of these wells, nur.bers 3 and 17 in late
December 1973. After analyzing the recorder charts, effects of pumping,
location, and surrounding conditions, it was decided that well number 3
was the more suitable well. Since other regulatory wells were nancd for nearby
lakes such as James 11 and Cal;r 33A, this well was designated as Grace 3.

Two nrethlods were used to determine the regulatory method in Grace 3. Tie
first was based on the total allowable witndrawal as interpreted from the
Five Party Agreement aid tihe second mrthod was based on the water crop

S.The "Water Plant E-100" well has been used as the regulatory well for the
southwest section of the Cosme-Odessa Well Field since regulations were
imposed in June of 1973. At the April 10, 1974 Governing 8oard meeting
it was reconriended by the staff that this well be discontinued as a regulatory
well. In its place an abandoned production tel11 known as Grace 3 was
adopted as the new regulatory well. The following is a synopsis of the
study of ootn wells and suggestions, for the future responsibilities of
the staff.


Well E-100 becarv one of the three regulatory wells for the Cosme-Odessa
Well Field as stipulated in Order 72-1 and dated February 9, 1972. Well
E-100 was ciosed to be a regulatory well on the basis of its location,
availability, long period of record, and purpose. Since rany private
Irrigation wells were in close proximity to the well field it was decided
that chloride contamination of the Floridan Aquifer should be the criteria
for estaoblishing the regulatory level. The regulatory level was developed
using tle Gnyucn-lierzburg Theory which is based on thie density differences
"between fresh and salt waters. The theory"that for every foot of fresh
water stored in tne ground above mean sea level, 40 feet of fresh water
will occur below ncean sea level.

Althoughi the regulatory level was based on chloride contamination the
. actual water levwl in the well should reflect well field conditions.
Continued difficulty by St. Petersburg to maintain regulatory levels,
even wien production in the lower part of t;e well field was reduced,
indicated this to not bo the case and also indicated a need for an
evaluation of tnie well. Approximately ten nontns ago an evaluation
was begun to determine if E-100 ias a valid chloride monitor and/or
regulatory well.
