WATER QUALITY -QUANTITY MONITORING
AND ANALYTICAL SERVICES
Prepared By
Environmental Research & Design, Inc.
August 3, 2001
EXHIBIT A: SCOPE OF SERVICES
Environmental Research & Design, Inc. (ERD) will perform, at a minimum, the following
services for the City of Sebastian (City):
Task 1: Attend Project Kick -Off Meeting: The ERD Project Director will attend a
project kick-off meeting with the City of Sebastian and the SJRWMD to review
the overall project objectives, scope of services, primary contacts for each
organization, project schedule, and meeting schedule.
Task 2: Prepare/Submit Project 0 -AM ERA will develop a QAPP for all proposed
field and laboratory activities. The plan will be based on existing ERD field
collection and laboratory analysis procedures outlined in ERD's CompQAP.
Field monitoring and laboratory activities will be performed over a six-month
period which includes both wet and dry season conditions.
Task 3- Install Automatic Samplers and Cpllect Samples fStonecrop Basin): ERD will
install automatic sequential samplers with integrated flow meters at the two m4jor
inflow points and at the outfall from the pond (3 locations total). The flow
meters will continuously measure flow rate, including stormwater runoff and dry
weather baseflow, for a six-month period, including three wet months and three
dry months. At least one flow composite sample will be collected from each of
the three samplers once each week for the six-month monitoring period (3
samples/week x 26 weeks = 78 samples total). All collected samples will be
analyzed for the following parameters:
a.
Total Phosphorus
b,
Orthophosphorus

Task 4: Perform Fidd Measurements and Collect Samples Routh Prong): ERD will
perform field measurements of water flow rate and collect water quality samples
at the S.R. 512 Bridge, the West Canal, the Radial Gate, and the Elkcam Dam
(4 locations total). Field measurement of water flow rate and collection of
baseflow water quality samples will be performed once every two weeks for a
period of six months (3 wet season and 3 dry season). A total of 52 baseflow
samples will be collected for analysis.
Once every two weeks, ERD will perform field measurements of flow rate at the
S.R. 512 Bridge, the West Canal, the Radial Gate, and Elkcam Dam using the
velocity/cross-sectional area method at each site. Velocity measurements will be
performed at known distances across the cross-section using a Marsh-McBimey
electromagnetic velocity meter. The spacing between the velocity measurements
will be determined in the field and will be such that not more than 10% of the
total flow is represented by any one vertical cross-section. The depth at each
section will also be measured using the flow meter measuring rod. If the water
depth is less than 2.5 ft (0.75 m), velocity will be measured at 60% of the total
water depth. If the water column depth exceeds 2.5 ft (0.75 m), velocity
measurements will be performed at 20% and 80% of the total water depth, with
the mean channel velocity determined by taking the average of the two
measurements. A graduated tape will be stretched across each channel so that
reference locations can be determined for each simultaneous measurement of
velocity and water depth.
The velocities will be integrated over the cross-sectional area to determine the
actual flow rate. The field measurements will be used to calibrate the stage and
rating curve information available from the SJRWMD and USGS so that the
approximate flow rate at any point in time can be estimated based on the stage
information.
Discrete water samples will be collected at each monitoring site prior to
performing flow measurements. The samples will be returned to the ERD
laboratory and analyzed for the following parameters:
a. Total Phosphorus (filtered and unfiltered)
b. Orthophosphorus
C. Total Suspended Solids
d. Volatile Suspended Solids
e. NO,
f. TK13 (filtered and unfiltered)
g. Ammonia
In addition to the baseflow flow measurements and sample collection, ERD will
utilize the existing District cellular communication system to identify storm event
conditions in the watershed. During a minimum of six storm events during the
six-month monitoring period, ERD will perform additional measurements of flow
rates and collect stormwater samples at each of the four locations. Selection of
target storm event characteristics will be performed jointly by ERD and the City.
The stormwater samples will be analyzed for the same parameters as the baseflow
samples. For at least 10 of the baseflow and stormwater samples, grain size
distribution will be determined for the inorganic suspended solids component of
the water sample,

Task 5: Estimate Basefl /Runoff Volumes: The total baseflow and stormwater
volumes for the three wet months and the three dry months will be estimated by
ERD for each of the seven locations. Water volumes for the Stonecrop Basin will
be based on continuous flow monitoring of the two inflows and outflows. For the
S.R. 512 Bridge, the West Canal, the Radial Gate, and the Elkcam Dam, water
volumes will, be estimated using the field measured flow rate in conjunction with
curve data from the SJRWMD. The field measurements of flow rates will be
used to calibrate the rating curves at each of the four locations to estimate a total
baseflow volume and stormwater volume for the three wet months and three dry
months.
Task 6: Develop Mass Loadings: Using the estimated water volumes and measured
pollutant concentrations, ERD will develop mass pollutant Ioadings for the three
wet months and three dry months at each location. Overall mass pollutant load
reductions will be calculated for each parameter for the Stonecrop Basin and for
other locations where pre -BMP data is provided by the SJRWMD,
Task 7: Prepare/Submit S3RWMD QA/QC Forms: ERD will prepare and submit
appropriate SJRWMD QA/QC forms for field sampling and laboratory analysis
in accordance with SJRWMD requirements.
Task 8: Review Meeting - Project Results: The ERD Project Director will attend a
review meeting with the City of Sebastian and SJRWMD to discuss the project
results.
Task 9: Prepare Draft Rept: Once all project tasks have been completed, a Draft
Final Report will be prepared and submitted to the City of Sebastian and the
SJRWMD for review which summarizes all project work tasks, A total of 6
copies of the Draft Final Report will be submitted.
Task 10: Review Meeting - Draft Report: Once all reviews have been completed, ERD
will attend a review meeting to discuss comments on the Draft Final Report.
Task 11: Prepare Final Report: ERD will prepare and submit 6 copies of the Final
Report to the City of Sebastian and SJRWMD based on comments received on the
Draft Report.

Exhibit 1 - City of Sebastian, Stonecrop Basin & Elkcam Dam BMPs
BACKGROUND
In 1996 the City of Sebastian entered into a cooperative agreement with FbEP (through
management of a 319 EPA Grant and with the St. Johns River Water Management District
(District) to develop, construct and monitor for efficiency two stormwater BMPs.
Pre -BMP monitoring was performed 1998-1999 at three locations as indicated in figure 1.
The data was used to perform initial calibration of an HSPF/Basins model for the South Prong
of the Sebastian River. The model allows estimation of annual pollutant loads conveyed by
the South Prong and two of its main tributaries: Central Canal (SRWCD) and the Elkcam-
Collier-Shumann waterway system for which the Elkcam Dam is the control structure. Since
this monitoring occurred prior to the new dam's construction, the results will be considered as
pre -BMP loads for that reach. Pre -BMP monitoring was not conducted for the Stonecrop
Basin.
SJRWMD monitoring stations currently exist at the Elkcam Dam, West Canal and Radial
Gate stations. These stations are equipped with staff gauges, stage recorders, tipping bucket
rain gages, CRI OX dataloggers and cellular communication systems. The USGS operates a
stage recorder at the S. R. 512 Bridge and receives the data through telemetry. Stage -
discharge rating curves currently exist for all of the above sites except the Elkcam Dam.
SJRWMD personnel are in the process of developing a rating curve for this new structure.
Monitoring equipment has not been deployed at Stonecrop Basin, so no flow or loading data
is available.
BMP DESIGN
Figure 1 shows the locations of the structural BMPs and required monitoring stations. For
Stonecrop Basin, determination of treatment efficiency must involve upstream/downstream
monitoring. Basin design, showing points of inflow and outflow, is depicted in figures 2 and 3.
MONITORING PLAN REQUIREMENTS
The primary goal of the monitoring is twofold,
calculate the annual load of TN, TP and TSS
Sebastian River. Second, data collected will
annual TN, TP and TSS loads that are attain
Practices (BMPs).
First, data will be collected and used to
being discharged to the South Prong of the
be used to estimate the percent reduction in
,d by recently constructed Best Management
As a secondary goal, the data collected will be used by SJRWMD staff to calibrate a District
HSPF/BASINS model for the South Prong of the Sebastian River. For this reason, some
monitoring sites will require discrete sample collection, while composite samples may be
collected at others (those associated with the Stonecrop Basin BMP).
Approximately 94% of the Stonecrop drainage area enters the treatment basin through the
two northern culverts. The remaining six percent drains to three small culverts located on
either side of the basin at the lower end near the weir (see figure 2). Flow measurements
and water quality monitoring may only be performed at the two northern inflow points.
Pollutant loading rates for the ninety-four percent of the contributing drainage area will be
determined from these data. Loading from the remaining six percent may then be calculated
by area -weighting the aforementioned loading rate for each pollutant and applying these
values to the unmonitored areas.
A determination of the pollutant loads leaving the Stonecrop treatment basin may be made
directly through measurements and monitoring at the outfall (weir); alternatively, loading
leaving the treatment basin may be estimated by using the data collected from the other
stations, i.e., loading values determined at Elkcam Dam, Radial Gate, and West Canal would
be subtracted from loading values determined at the S.R. 512 bridge.
The scope of work should include a detailed monitoring plan for 1) the collection and analysis
of ambient and storm -event surface water samples, 2) the continuous measurement and
recording of flow rates, 3) the continuous measurement and recording of rainfall within the
project boundaries, 4) calculation of pollutant loads both on an event basis and normalized
for annual loading, and 5) reporting of data and other information. Water quality and flow
data shall be obtained at the locations shown in figure 1 . Parameters to be analyzed (at a
minimum) are: Total Phosphorous (TP -filtered and unfiltered), Orthophosphate (1304), Total
Suspended Solids (TSS), Volatile Suspended Solids (VSS), Nitrate plus Nitrite (NOx), Total
Kjeldahl Nitrogen (TKN — filtered and unfiltered), Ammonia as N.
The filtering of samples for TP and TKN analyses is necessary to provide data on the
fractions of dissolved versus particulate nutrient concentrations needed for model calibration.
Thus, a sufficient volume of surface water will be needed to allow the splitting of each sample
into filtered and unfiltered portions. However, samples collected for the Stonecrop BMP
treatment efficiency analysis need not be analyzed for the dissolved fractions of TP and TKN;
therefore, those samples do not require filtering.
Additional samples will be collected and analyzed over the course of the monitoring period
(storm and ambient sampling events) for the purpose of determining the grain size fractions
(sand, silt & clay) of the inorganic suspended solids within the water column.
Applicants are encouraged, but under no obligation, to make use of existing equipment and
data for the selected sites. This will require coordination with the SJRWMD and USGS to
obtain access to their equipment and/or data. Applicants will need to evaluate the adequacy
of monitoring stations at Elkcam Dam, Radial Gate, West Canal and S.R. 512 Bridge in terms
of useable area, accessibility, safety and security. Applicants should also evaluate the
adequacy of available data, including status of the ratings on structures, to achieve the goals
of this project. It is anticipated that additional flow measurements as checks on existing
rating curves and changes in physical controls will be required for some stations.
