program:

ID-A, ID-B, ID-C, ID-D and ID-E L-l, L-2, L-3, L-4, L-5 and L-6; G-6; G-7; G-21; G-27; G-28; G-35.

These wells are designated as to location on Plate 3.1.

3.2 Monitorin Fre uenc 4

The following tabulation presents the schedule of measurements for the respective wells listed in the preceeding section:

G 7i 21I 28'5 1st of January,

March, May and November G-6 and G-27 3.3 Parameters The following data shall be collected at e'ach well at the times specified in the preceeding section:

a.

Ground-water Elevation (ft.)

Measured inside the casing from top of casing.

Elevation of top of casing is known.

b.

Surface-Water Elevation (ft.) Measured outside the casing from top of casing.

c.

Conductivity (umhos)

Measured with depth to total well depth.

Readings shall be obtained at one Q) foot intervals.

d.. Temperature

( C)

Measured the same as conductivity.

e.

Water Sample Collection One water sample per well DAMSS 8 MOORS

should be obtained for laboratory titration of chloride ion content.

Depth of sample collection is not constant, but approximately half the water samples should be obtained from within the first twenty feet of the water column in the well.

Generally, this portion of the water column contains the transition from water of low chlorinity to water of higher chlorinity.

These

samples, in combination with

)

water samples from deeper

depths, should provide chloride data, which generally spans the entire spec-trum of chloride ion encountered.

3.4 Monitorin Procedure The following procedure shall be followed in collection of raw field data:

1.

Calibrate the Hydrolab TC-2 Conductivity-Temperature Meter prior to each day of the monitoring using two standard saline solutions of 15,000 umhos and 90,000 umhos.

The instrument shall be calibrated in ac-cordance with the procedures established in Section 3.7, Equipment Calibration.

2.

Measure both surface water elevation and ground-water surface elevation at each well by measuring from top of well casing.

3.

Insert Hydrolab probe to a depth of one (1). foot below water level in well; when meter needle stabilizes, read and record conductivity and temperature.

4.

Repeat procedure in Step 43 at intervals of one (1) foot to bottom of well.

DAMSS 8 MOORS

5.

Obtain water sample for chloride ion titration in accordance with recommendations in Section 3.3(e)..

Hater samples are obtained with a Masterflex Pump.

When taking a sample with the pump, a minimum of 800 ml of water from the desired sampling depth shall be pumped through the line to insure the sample is representative and not contaminated by water left in the line from a previous sampling station.

Sample water shall be pumped directly into clean, dry bottles which shall be tightly capped to prevent contamination of the sample.

6.

After monitoring every third well, the calibration of the Hydrolab probe shall be checked with the 90,000 umhos/cm standard saline'olution in accordance with procedures described in Section '3.7.

Note, however, that the instrument shall not be adjusted at this time.

7.

After each day of monitoring, the conductivity of the 90,000 umhos/cm standard solution and the calibration of the Hydrolab probe shall be checked in accordance with procedures in Section 3.7.

3.5 Data Verification Xn order to check the validity of the conductivity

data, the relationship of conductivity versus chloride is I

determined each month by regression analysis.

This analysis requires the use of an independent variable (true variable) and a dependent variable.

Chloride content determined by QAMSS S MOORS

0

laboratory titration is used as the true variable and the conductivity vaxiable is adjusted to the line of best fit by the method of least squares.

Therefore, for the conductivity-chloxide relationship to be valid for the determination of the position of isochlors, the chloride determination by laboratory titration must be correct.

In order to reduce the possibility of this source of errox, the raw titration data and raw conductivity data shall be immediately plotted on the historical conductivity-chloride relationship as shown on Plate 3.2.

The majority (75 percent} of the plotted raw data points should fall within the variance shown for the historical relationships.

The remaining 25 percent of the points. should be reasonably close to the historical relationship.

For conductivities less than 10,000

umhos, the historical relationships are less definitive.

For these conductivities, the ratio of the raw titration value (parts per thousand).

to the corresponding raw conductivity value (umhos/cm} should be reasonably close to the following historical ratios:

Conductivity umhos/cm Rat:io Less than 2000 2000 6000 6000 10000

0. 10.0

0. 237

0. 33.4 In addition to these two check methods, the raw points

should be inspected for direct proportionality.

In other words, the chloride content increases with increasing con-

ductivity.

Any two relative data points which reverse this relationship should be checked for probable error.

If, at any time, data is suspected to be in error, the following steps shall be taken:

l.

Retitrate the suspect water sample to determine chloride content.

Replot this titration data versus the corresponding conductivity data and reinspect for direct proportionality.

2. If data is still suspected to be in error after the retitration, then the well(s) in which the suspect data occurs shall be remonitored in accordance with the procedures set forth in Section 3.4.

The conductivity, temperature, water level and titration data shall be transmitted by phone to Dames 8 Moore in Boca Raton.

Dames 6 Moore will recheck the titration data for proportionality and variance from the historical relationship in accordance with methods presented in previous paragraphs.

The water level, temperature and conductivity data will be compared with the previous month's data and with historical data from periods of similar seasonal conditions.

(Water level fluctuation, precipitation and air temperature are among the factors to be considered when choosing times of similar seasonal conditions.)

If any water level, temperature and/or conductivity data exhibit abnormal

changes, the wells in which these changes occur will be remonitored in accordance with procedures set forth in.Section 3.4.

Suspect wells will be remonitored and checked until Dames a Moore is I

1 j

il PAMQS 8 MOORS

satisfied that the data represents actual ground-water conditions.

At this time, the data will be processed in accordance with Section 3.6.

The initiation of the monitoring each month shall allow sufficient time for checking suspect field data.

Therefore, the monitoring should be initiated at least five working days prior to the 1st of each month.

3e6 Data Processin The raw field data shall be entered on provided. standard forms.

This standard form is shown on Plate 3.3.

This form shall be filled out in triplicate.

Distribution of the data shall be in accordance with the following:

a.

Original To FPGL Environmental Department who will forward to FCD.

b.

One Copy Retain on file at Land Management offices at Turkey Point.

c.

One Copy Forward to Dames

& Moore in Boca Raton office.

Data shall be forwarded to FCD within-72 hours after the first day of each month.

Examples of completed forms are presented in the attached Appendix.

Conductivit Calibration Prior to each day of monitor-ing, the instrument shall be calibrated in accordance with the procedures established hereinafter and the appropriate information entered on the Calibration Log (plate 3.4). in the space designated "Before Monitoring".

The calibration of the Hydrolab TC-2 conductivity meter is accomplished by the use of two potassium chloride,NC1}

solutions prepared in accordance with ASTM D1125-64, Standard Methods of Test for Electrical Conductivity of Water.

The procedure is as follows:

'a.

Prepare one solution of approximately 90,000 umhos conductivity.

1.

Dissolve approximately 60.0 g of KCl (weighed, in air) in tap or drinking water and dilute to 1 liter.

2.

Measure conductivity of solution with a Beckman RC-19 conductivity bridge using a certified cell to determine the "true" conductivity of the s'olution.

3.

Adjust Hydrolab unit to read the value obtained with the Beckman conductivity bridge.

b.

Prepare one solution of approximately 15,00Q umhos conductivity.

1.

Dissolve approximately 7.5Q g of KCl (weighed in air} in tap or drinking water and dilute to 1 liter.

2.

Measure conductivity of solution with Beckman RC-19 conductivity unit using certified cell.

3.

Read conductivity of solution with Hydrolab unit.

DAMQS8 MOOAQ

If the reading obtained with the Hydrolab unit differs from the reading for the low conductivity solution given by the Beckman unit by more than 1,000

umhos, the conductivity of the 90,000 umhos solution shall be rechecked with the Beckman unit and the procedure repeated.

Calibrating the meter with a solution of high conductivity reduces the percent error introduced when calibrating the instrument at the lower end of 'the conductivity range.

The 15,000 umhos solutions serve as a check on the accuracy of calibration at 90,000 umhos.

In order to insure that the instrument is maintained in calibration throughout each day of monitoring, the 90,000

'mhos/cm standard saline solution used in the initial calibration shall be carried to the field and the solution should be read after monitoring every third well.

The reading given by the instrument should be recorded on the standard calibration log (Plate 3.4} in spaces designated "During Monitoring".

However, the instrument shall not be adjusted in the field to the reading given by the standard solution.

Upon returning to the laboratory after each day of

. monitoring the conductivity of the 90,000 umhos/cm solution shall be checked with the Beckman RC-19 Bridge in order to assure that the conductivity of the standard solution has not changed throughout the day.

The standard solution shall

\\

then be read with the Hydrolab.

This calibration sequence shall be entered on the calibration sheet in the space labeled "After Monitoring".

easveas 8 svaoosaa

The calibration will be used to develop "drift curves" to be used in correcting the data.

If the "After Monitoring" Examples of "completed forms are presented in the attached a.

Turn the instrument to "temperature zero" and adjust calibration sequence yields a reading deviation exceeding five (5) percent of the total reading, the data shall be corrected using the drift curve.

In summary, the maximum "I

allowable reading deviation for a 90,000 umhos/cm solution 1

would be + 4,500 umhos/cm.

Tem erature Calibration The Hydrolab TC-2 temperature lI;,

meter standard for calibration is internal and the procedure used shall be as follows:

to read -5 C.

b.

Turn the instrument to "temperature calibrate" and adjust to read 45 C.

c.

Prepare two H20 solutions at temperatures of approxi-mately 20 C and 30 C.

d.

Compare the temperatures measured with the Hydrolab unit to those obtained with a highly accurate labora-tory thermometer.

e. If the Hydrolab and the thermometer agree within 0.5 C, the temperature meter is considered calibrated.

f. If the two do not agree, use the following procedure:

l.

Adjust the Hydrolab unit to read the measurement given by the thermometer in the 20 C solution. DAMSELS 8 IVEODRH

2.

Read the 30 C solution with the'Hydrolab unit and thermometer.

If the readings differ, adjust the Hydrolab unit to read the same as the thermometer.

3.

Again read the 20 C solution with both instruments.

If there is a difference, adjust the Hydrolab to equal the thermometer reading.

4.

Repeat, this alternating procedure until the Hydro-lab 'unit will read both solutions within 0.5 C.

'4. 0 INTERCEPTOR DITCH OPERATION 4.1 Introduction The purpose of the Interceptor Ditch is to prevent inland movement of cooling canal water by maintaining a

seaward ground-water gr'adient during times when a natural seaward gradient does not exist.

During the wet season and the early part of the dry season, a natural seaward gradient usually does exist.

During the rest of the year,

however, it is necessary to artificially generate a seaward gradient east of Levee 31 Borrow Canal by pumping water out of the Interceptor Ditch.

The procedure for monitoring the ground-water gradient and operation of the Interceptor Ditch are presented in the following sections.

4.2 Monitorin Locations Surface water elevations shall be monitored at staff gages located in Cooling Canal 32, Levee 31 Borrow Canal and the Interceptor Ditch at five locations relative to Lines A,.

B, C, D and E, as shown on the inset, Plate 3.1.

Hhen pumping of the Interceptor Ditch commences, additional data shall be obtained at each of the two ID'pump stations.

Locations of the pump stations are also shown on Plate 3.1.

A generalized Interceptor Ditch pump station is shown on Plate 4.1.

Each station consists of two variable discharge pumps with the maximum capacity of each equaling 15,000 gpm. MMES 8 i%'TOO$ZD

0

charts, both of which are located in each discharge weir.

A pump rating curve relating water elevation (ft.) in the discharge weir versus pumping rate c ~

(gpm) is shown on Plate 4.2.

Stevens recorders Stevens continuous water level recorders shall be in operational mode at each pump discharge weir at commencement, of Xnterceptor Ditch pumping.

Procedure for operating the recorders are presented in the attached Appendix.

Shaded areas designate the applicable time and gage scales for these recorders.

4.5 Pum in Criteria As long as a natural seaward ground-water gradient

exists, pumping of the Xnterceptor Ditch is not required.

The following criteria defines when a natural seaward gradient exists and when the Xnterceptor Ditch must be pumped to create an artificial gradient east of Levee 31 Borrow Canal.

'Seaward Gradient A natural seaward gradient exists when the Levee 31 water surface elevation (ft.,

MSL) is greater than 0.2 feet higher than the water surface elevation (gt.,

MSL) in Cooling Canal 32.

Xf this criterion is not met, a natural seaward l'radient still exists if the water surface elevation (ft., MSL) in Levee. 31 is.greater than 0.3 feet 0

higher than the water surface elevation (ft., MSL) in the Interceptor Ditch.

I Landward Gradient If a seaward gradient condition is not met, then pumping of the Interceptor Ditch must'e initiated to artificially create such a seaward gradient.

Pumping rates shall be adjusted so that the water surface elevation (ft., MSL) in the Interceptor Ditch is on the order of 0.3 feet lower than the water surface elevation (ft., MSL) in Levee 31.

Pumping shall be terminated when the criteria for a natural seaward gradient is met. (see preceding subsection entitled Seaward Gradient).

The flow chart on Plate 4.3 depicts the requirements for pump operation.

This chart shall be referred to each time a set of water elevations is obtained to determine when II pumping is or is not required.

The above criteria apply to each section of,the Inter-ceptor Ditch, individually.

As can be seen on Plate 3.1, the pump stations divide the Interceptor Ditch into three segments.

Each segment is evaluated separately with respect to the operating criteria.

One section, therefore, might require pumping while another might not.

In those segments V

of the Interceptor Ditch where two lines of staff gages occur (the northern and the southern segments),

pumping shall be initiated when either one of the lines of staff gages fails to meet the specified criteria for a seaward VAWI~SQTv1OC'A~J

gradient.

Adjustable intake gates (stop-logs) in each pump intake basin allow for various pump combinations to diawdown specific Interceptor Ditch segments.

4.6 Data'rocessin Upon seasonal initiation of pumping of any section of the Interceptor Ditch, the Director of the Resources Planning Department, Central G Southern Florida Flood Control District.,

located in Nest Palm Beach, shall be immediately notified by telephone.

The data, as described in the preceding section, shall be submitted monthly to the Flood Control District.

The data shall be compiled on the provided forms.

These forms are shown on Plates 4.4, through 4.7.

Examples of completed forms are presented in the Appendix.

'I The forms shall be filled out in triplicate.

Distribu-tion shall be in accordance with the following:

a.

Original To FPGL Environmental Department who will forward to FCD.

b.

One Copy Retain on file at FPGL Land Management offices at Turkey Point.

c.

One Copy Forward to Dames 6 Moore in Boca Raton.

4.7 E ui ment Maintenance Occassional cleaning of the staff gages is required when algae and other marine gxowths inhibit reading of the staff gages.

Care must be taken when cleaning to prevent, damage or movement to the staff gages.

When pumping of the Xnterceptor Ditch is required, Stevens continuous water level recorders must be operating in each pump discharge weir.

General operation and mainten-ance procedures for these recorders are given in the Appendix.

The specifications for the recorders located at the pump stations are highlighted on Appendix pages by shading of applicable information.

Constant improvements since the year 1911 perfected through field use and the skill gained over a half century of manufacturing precision engi-neering instruments have made it the preferred recorder for river hydrography, and for any installation where long term operation is required or in which wide fluctuations in water levels occur.

Operation is Simple Reduced to its basic function, the recorder accomplishes the following:

A strip chart is moved at a predetermined rate controlled by a clock movement. A marking stylus moves laterally across the chart in direct prooortion to changes in water level.

Thus, the result is a graphic record of water levels against time.

A single strip chart will last from 25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> to 2 years, de-pending upon gearing and type of chart drive. Both English and nlefric models are offered.

FIG. 2 Unlimited Range Reversal of the marking stylus at each margin assures unlim-ited range without interruption, or reduction in scale. For easier interpretation, an optionci reversal indicator can be installed at the factory-or in the field. The stylus marks the chart so that reversals on rising stages can be distinguished from falling stages (See Optional Equipnterfrj.

Synchronous Motor Drive-for time scales up to 864 inches per day. For AZ operation only.

Where water flow is artificially controlled (such asin the fore-bays and tailraces of power plantsJ a faster time scale is de-sirable for making the record of the wide and rapid fiuctua-tions more legible. In all cases, the slowest time scale consis-tent with legibilityshould be used.

The weight drops from 4.7 to 5.7 feet per month, depending on time scale, and this can be reduced by increasing the weight and interposing movement reduction sheaves in the clock weight cable.

A capillary pen (of special Stevens designJ containing ample ink in its Lucite reservoir for several months'peration is pro-vided as standard equipment. A pencil may be substituted if desired, but pen is recommended where sensitivity is essential.

A supply of ink (or pencils) is furnished with each Recorder.

Stevens Chart Ink (black, red or greenJ is prepared from a special formula that flows freely regardless of seasonal tem-perature.

Strip Charts

-with English or Metric Scales Strip charts are printed on high rag.content tracing quality paper to minimize humidity effects. Several days of record are normally visible with recorder in operation.

Time Scales Designated by the number of inches of chart utilized in one day, standard time scales are easily interchanged in the field by substituting, gears.

Faster time scales may require a clock change as well.

English Charts are graduated with inch and 0.10 inch divisions.

Chart size 10.inch wide x 25 yards (22.8 m) long.

Metric Charts are divided into centimeters and fifths. Chart size: 25-cm. wide x 25 yards (22.8 m) long.

The relationship between the rotation of the float pulley and the marking stylus movement is set by gearing.

Changes in the gearing, or pulley circumference, thus affect the ratio between the chart record and water-lettel changes. This ratio is known as Gage Scale and designates size of record in relation to the level fluctuations. For

example, a 1:6 Gage Scale means that the record will be 1/6 actual size. (Standard English Scales are mulliples of the ratio 1: 12-Metric scales are multiples ofI:10.)

Changes in gage scale, within a specific pair as listed in Table 3 (such as a change from 10:12 to 5:12), are accom-plished by adding an annular ring to change pulley circum-ference from 18 to 36 inches (or from 375mm to 750mm). Changing scale between standard pairs (such as from 1:6 to 10:12) is accomplished by exchanging float pulley standards.

Either change may be done easily, with-out special tools.

Instruments may be converted in field 1'rom English sys-tem to Metric system, and vice versa. IVrite for details.

c-FIG. 5 Schematic Cutaway illustration of a typical Stevens Type A Water. level Recorder installation with stilling well and gauge house.

Tilne Marker. With this accessory an auxiliary pen marking on thc left margin of the chart makes a jog at certain elapsed time intervals. The action is controlled by the clock so that the jogs correspond to clock time and not to time divi-sions on the chart. The Time Marker record serves as a basis for applying corrections to the graph for possible errors due to humidity effects.

The iogs are adjusted to correspond to even hou.s or other even tim intervals by an index setting on a

graduated disk. Time intervals are marked every 2A inches corresponding to 6, 8, 12, 24 or 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> depending on the time scale. Re-corders may be ordered with this accessory or it may be installed in the field without special tools.

Reversal Indicator. This device eliminates pos-sible confusion in interpreting graphs on which t

reversals of the stylus occur. Indicator makes a continuous pen line on right margin of chart, with a long indentation for a reversal in one direction and a short indentation for a reversal in the other direction. Recorders may be ordered with this accessory or it may be installed in the field without special tools.

Counter Indicator.

Gage heights can be read directly, with indicator visible through glass po'rt in recorder. Indicator can be factory or in-the-field installed, without special tools.

r AuxiliaryPencil. Insures against loss of record in the event pen ceases to function. This accessory attaches onto stylus carriage and provides a

duplicate pencil record.
