| MEMORANDUM OF AGREEMENT
AMONG
THE ARMY CORPS OF ENGINEERS
THE SOUTH FLORIDA WATER MANAGEMENT DISTRICT
AND
THE NATIONAL PARK SERVICE
FOR THE PURPOSE OF PROTECTING
THE QUALITY OF WATER ENTERING
EVERGLADES NATIONAL PARK
Since the Congress, in
connection with the Everglades National Park, has
directed the Corps and the National Park Service "to reach an early
agreement on measures to assure that the water delivered to the park is of
sufficient purity to prevent ecological damage or deterioration of the
park's environment." (River Basin Monetory Authorizations and Miscellaneous
Civil Works Amendments, Senate Report No. 91-895, p.24); and
The quality of existing water
deliveries to the park does not depart
significantly from that of waters which have not been altered by the works
of man; and
The Corps, the National Park
Service (NPS), and the Water Management
District (WMD) are concerned that surface waters delivered to the park are
not degraded;
THEREFORE, the Corps, NPS, and
WMD (parties) mutually agree to the
following:
1. Water
Quality criteria for 27 parameters as enumerated in appendix A
shall apply only to surface waters delivered to the park. Federal, State,
and local water quality criteria which are more stringent than those
appended criteria shall continue to apply.
2. The
concentrations of pesticides/herbicides in surface water deliv-
ered to the Park are to be 0.0 Actual concentrations are to be below the
limits of detection. A listing of pesticides/herbicides is shown in
Appendix B.
2
3. The Corps
shall collect and analyze for specified parameters (see
appendix A) and pesticide/herbicide residues (see appendix B) in surface
water from delivery water locations (see appendix C), sediment from the
inflow stations will also be tested for trace metals and pesticide/
herbicides. Sampling frequencies are described in appendix C.
4. The WMD
shall collect and analyze for specified parameters (see
appendix A) and pesticide/herbicide residues (see appendix B) in surface
water from watershed locations (see appendix D). Sampling frequencies are
described in appendic D.
5. The WMD
shall also conduct diurnal studies for dissolved oxygen,
specific conductance, pH, and water temperature at the inflow stations as
described in appendix C.
6. All sample
collection data analyses shall be reported monthly to
NPS, Corps, and WMD.
7. The Corps,
NPS, and WMD shall meet at such times as may be necessary
at the request of any party, but not less frequently than once a year to
review results of this agreement.
8. Should water quality
criteria not be met and a clear and present
danger to water quality has been determined to exist by the parties,
appropriate actions or such legal process as may be necessary to restore or
protect the quality of water entering the Park shall be taken by the Corps,
NPS, and WMD.
9. This agreement may be
revised upon mutual consent of all parties.
A 90-day review period will be allowed for review of proposed changes to
this agreement.
10. The Corps, NPS, and
WMD recognize that the data base for the
appended standards needs periodic review. Therefore, the standards will be
reviewed for adequacy and necessary revisions in 1984 and periodically
thereafter.
IN WITNESS THEREOF, THE PARTIES HERETO HAVE
SIGNED THIS AGREEMENT ON THE DATES INDICATED.

| RATIONALE FOR UPPER LIMITS
Water quality data from inflow stations to the Park (S-12C and L-67A) for
1970-1978 were analyzed. From this data, upper limits for each parameter
were computedbased on control chart theory wich uses the mean, standard
deviation, annual sampling frequency and control line factor.** These upper
limits are to be used as criteria against which future water quality data
could be compared.
* Annual mean not to exceed this value. For
dissolved oxygen, annual mean
not to be less than this value.
