ORDER GRANTING PERMIT PURSUANT TO
HEARING BEFORE GOVERNING BOARD
This Matter came on to be heard by the Governing Board of Southwest
Florida Water Management District at a Public Hearing on April 4, 1978. Said
Public Hearing, being duly and properly noticed, was conducted at District Head-
quarters, 5060 U. S. Highway 41 South, Brooksville, Florida, and all parties
hereto were present or given the opportunity to be present, and, together with
the general public, were given an opportunity to present testimony and evidence.
The Board having reviewed the application and all documents in the File of
Record, having heard testimony, and having received and examined all documentary
evidence, makes the following
FINDINGS OF FACT:
1. Applicant, Pinellas County, leases lands and controls water rights
in and to such lands consisting of 1,929 acres in parts of Sections 1, 11, 12 and
S13, Township 27S, Range 16E, Pinellas County, and Sections 5, 6, and 7, Township 27S,
: range 17E, Hillsborough County, Florida, and has developed a well field thereon
consisting of fifty-eight (58) production wells and other related facilities to
produce a portion of the total public water supply needs of the Pinellas County
Water System. The well field is known as the Eldridge-Wilde Well Field.
| 2. The well field has been operated since 1956. By 1972, production
: at the well field had expanded to such an extent that the Southwest Florida Water
Management District (Regulatory) initiated public hearings thereon. Through a
1 series of Orders beginning December 13, 1972, a well field monitor system was
developed and aquifer testing was conducted in order to establish regulatory
levels and controls for the management of the well field. Following a necessary
period of monitoring, testing, data collection, and evaluation, a program for
well field management was developed which provided for the regulation of pumping
in a manner so as not to cause the cumulative weekly average elevations of the
potentiometric surface of the Floridan Aquifer to be lower than the regulatory levels
Page 1 of 5
established for four (4) specified monitor wells. These Regulatory Levels were
accepted by the County by Stipulation dated October 22, 1974, and adopted by the
Governing Board by Order No. 74-1OR entered on November 13, 1974.
3. Chapter 16J-2, Florida Administrative Code, implemented
permitting rules governing the consumptive use of water in the District including
the well field site on January 1, 1975. From and after such date, the well field
was managed in such a manner that production was maintained at or below previous
quantities without exceeding the Regulatory Levels. The East Lake Road Well Field
was developed and placed in production to meet peak demand needs and increase
supply requirements of the Pinellas County Water System.
4. Pursuant to Chapter 373, Florida Statutes, and Chapter 16J, Florida
Administrative Code, Applicant timely applied on December 28, 1976, (Application
No. 7602673) to the Southwest Florida Water Management District for a Consumptive
Use Permit for the continued use of water in the quantities existing prior to
January 1, 1975. Such consumptive use quantity is 35,000,000 gallons per day on
an average annual basis at a withdrawal rate of 35,243,888 gallons per day (average
annual). Applicant has applied for authority to continue to make a combined
average annual withdrawal of 35,243,888 gallons of water per day, with a maximum
combined withdrawal rate not to exceed 59,300,000 gallons during any single day.
5. Applicant agrees that the maximum combined withdrawal rate shall
not exceed 55,000,000 gallons of water during any single day.
6. Objections have been filed in response to notice of this pending
application. The Board has considered the many objections and the concerns
expressed by the objectors. Some objections relate to lowered lake levels and
sink holes, but most relate to effects of production at the well field upon the
"water table beyond the well field property, and particularly adverse effects upon
surface vegetation alleged to be directly related to a decline in the mean annual
elevation of the water table. Whatever effects caused by this well field over
Page 2 of 5
the 20 years period of its existence would have commenced when the well field went
into production in 1957 and by December 31, 1974, would have reached present levels.
The water table effects directly attributable to production from this well field have
stabilized and have not worsened since 1974. Well field production has not exceeded
1974 existing use withdrawal quantities, and no increase over existing use has
"been requested by the Applicant. Permitting continued production from this well
field in the quantities of the Applicant's existing use should not cause additional
adverse effects in the area.
7. Of the 35,243,888 gallons per day (annual average) withdrawn from
the well field, 96% is used for public supply throughout the Pinellas County Water
System, 3% is used for irrigation within the well field, and 1% is used to augment
Lake Dan which is located within the well field. The portion of the withdrawal
consumptively used is 35,000,000 gallons per day (annual average).
8. A proposed Consumptive Use Permit has been reviewed by the Board.
A copy of the proposed permit is attached hereto as Exhibit 1 and is made a part
of this Order by reference. A copy of the proposed permit was submitted to the
Applicant for review and consideration.
9. The monitoring system developed for this well field was designed
to evaluate the effects of well field withdrawals upon the water resources of the
area and particularly water quality trends indicated by chloride and conductivity
levels in selected monitor wells. The data recovered to date has been unreliable
in many instances due to inadequacies in observation well design and to variability
in sampling techniques. An adequate and reliable monitoring program is vital to
provide early warning of salt water intrusion or other water quality trends.
10. A reliable-water quality monitoring program can best be achieved by
reconstruction of six of eight monitor wells so as to isolate the open intervals
in the bore holes at the depths specified in paragraph 10(a) of the proposed permit.
Reliable sampling can be best achieved by installation of sampling tubes and samples
taken in the manner specified. It is important that reliable data be available
^ as quickly as possible, so the construction should be completed within 8 months.
It is reasonable that paragraph 10(a) be made a condition of the permit.
11. The sampling program set forth in paragraph 10(b) of the proposed
permit is a reasonable modification of the current sampling, analysis and reporting
program and should be required as a condition of the permit.
12. The first chloride data from the reconstructed monitor wells will be
submitted by February 15, 1979. The Board desires that initial data gathered
Page 3 of 5
during a period to August 15, 1980, be reviewed and reported to the Board as it
relates to actual or potential lateral or vertical salt water intrusion. The
initial Consumptive Use Permit for the well field should be short term so that this
Board can review the data in connection with the renewal of the permit. For this
reason, the initial permit shall expire on December 31, 1980. Applicant should
apply for renewal during the third calendar quarter of 1980, and all available data,
in addition to data submitted by Applicant, shall be reviewed and evaluated at that
time to the end that this Board will be fully advised regarding the effects of
withdrawals from this well field upon the regional and areal water resources.
13. Continued stability of the well field and reasonable assurance that
continued production at the well field will not cause additional adverse effects
in the area can best be achieved by continuing to regulate this well field through
the existing Regulatory Levels management program. The present Regulatory Levels
continue to be reasonable, allow for the full beneficial use of the well field
in a reasonable manner consistent with the public interest, afford protection of
the water resources of the area, have been previously stipulated to by the Applicant,
and should be reimposed by Order of this Board as a condition of a Consumptive Use
Permit. Paragraph 10(c) of the proposed permit sets forth the Regulatory Levels
management program, and compliance with such paragraph shall be a condition of
14. The existing well field flow metering system should be maintained,
and withdrawals reported to the District weekly.
In accordance with the foregoing, and in consideration of applicable
laws and regulations, the Board makes the following
CONCLUSIONS OF LAW:
1. The Applicant has established that the existing consumptive use:
^ a) is a reasonable-beneficial use; and
b) is allowable under the Common Law
of the State of Florida.
2. The intended consumptive use is in compliance with the requirements
of Chapter 373, Florida Statutes, and Chapter 16J, Florida Administrative Code.

Wherefore, upon consideration, it is
1. That the Executive Director of Southwest Florida Water Management
District, or a duly delegated member of his Staff, is authorized and directed to
issue a Consumptive Use Permit pursuant to the above numbered application, in
substantially the form, and subject to the terms and conditions set forth in
Exhibit 1, attached hereto.
