WATER QUALITY SAMPLING PROGRAM
FOR THE LITTLE VENICE SEW AGE COLLECTION AND
TREATMENT PROJECT IN MARATHON, FLORIDA
BACKGROUND
The ocean side ofVaca key from Vaca Cut (east) to 94th Street (west), Marathon, Florida has a
large percentage of houses and trailers that are currently serviced by inadequate septic tank
systems or cesspit disposal. This area has been collectively called the "Little Venice" Service
Area, whereas in fact, Little Venice Subdivision is located on the westernmost portion of the
service area, The Little Venice Service Area includes approximately 540 residences (Figure 1).
The Little Venice Service area was selected as the first phase of wastewater improvements for
the Marathon Service Area because of the large number of homes on cesspits, the small average
size of lots, the density of the homes, and known water quality problems in the canals that occur
in the area, Water quality of the 89th - 91st Street canals was thoroughly studied in the 1984-
1985 as part of the Florida Department of Environmental Regulation Monitoring Study (FDER,
1987). That study demonstrated significant nutrient enrichment of the canals, high chlorophyll a
content, and a high coprostanol concentrations in sediments. Coprostanol is a break-down
product of cholesterol and is an indicator of fecal contamination.
The Little Venice Service Area will receive a low-pressure, vacuum wastewater collection
system that will transmit wastewater to a central treatment plant. The treatment plant will
produce effluent that meets or exceeds the current advanced wastewater treatment (A WT)
standards of 5:5:3: 1 (BOD5, TSS, TN, TP ) and will use a Class V injection well for disposal of
treated wastewater. Central collection and treatment of wastewater will remove a substantial
portion of nutrient loading into the canals by removing the sources of wastewater (Poorly
functioning septic tanks and cesspits).
SAMPLING PROGRAM
The purpose of this water quality sampling program is to document water quality improvements
in the canals of the Little Venice Service Area. The sampling program consists of two phases.
Phase 1 will be conducted for two years prior to the initiation of operation of the central sewage
treatment system. Phase 1 will establish existing conditions in the canals within the service area.
Phase 2 will be conducted for two years after initiation of the central sewage treatment system
and will document changes in water quality and sediment chemistry of the canals.
Four canals within the Little Venice Service Area will be selected for sampling (Figure 1). Canal
1 and 2 are a connected "U- shaped" canal system located at 112th Street. These canals may
receive better tidal flushing than other canals within the Service Area because of their flow-
through design and their relatively short length. Canals 1 and 2 are lined with single-family
-
residences that were constructed prior to 1970 and a high percentage of those residences are
thought to have no sewage treatment systems (cesspits). Canal 3 is located adjacent to 100th
Street and Canal 4 is located adjacent to 97th Street. Both canal 3 and 4 are dead-end canals that
are lined with single-family houses and mobile homes. Many of these residences are thought to
have poorly functioning septic systems or cesspits. The 91 st Street canal has been selected as a
reference canal and is located outside the Little Venice Service Area. Historic water quality and
sediment data exist for this canal (FDER 1987).
Field Sampling Regime
Nine sampling stations were chosen for this project: two per canal with an external site off 100th
Street canal (Figure 1). Stations were located at the mouth of the canal and at the dead -end.
Each of the 9 stations will be visited weekly via small boat. Surface and bottom measurements of
temperature, salinity, and dissolved oxygen (DO) will be preformed at each station. Duplicate
water samples will be collected in mid-channel at 1 meter below surface. Water samples will
also be collected just below the surface for bacteriological analysis. To ensure that we capture
the greatest potential terrestrial inputs, sampling will be performed on the low, low tide whenever
possible. Localized data from an ongoing study by FlU of the Florida Keys National Marine
Sanctuary will be used as the background ambient water quality in the nearshore waters for
comparative purposes.
Nutrient Analvsis
Water samples will be analyzed for total nitrogen (TN), total phosphorus (TP), and chlorophyll a
(Chla) by the Contractor's Southeast Environmental Research Center laboratory using standard
methodology outlined in the Quality Assurance Project Plan (QAPP). Once a month the samples
will be analyzed for the full suite of nutrients including ammonium (NH4 +), nitrate (NOx-)' nitrite
(N02-)' silicate (Si(OH)4)' soluble reactive phosphate (SRP), and total organic carbon (TOC).
Some parameters will not be measured directly, but calculated by difference. Nitrate (NO)-) will
be calculated as NOx' - N02'. Dissolved inorganic nitrogen (DIN) will be calculated as NOx- -
NO/. Total organic nitrogen (TON) will be defined as TN -DIN.
Diurnal Sampling
In addition to the weekly sampling program, each month two ISCO autosamplers will be
deployed at rotating sites which will be programmed to collect 12 samples per day over a 2 day
period. Water samples will be analyzed for TN and TP. Hydrolab datasnodes will accompany
the auto samplers and will measure and log temperature, salinity, DO, and pH on an hourly basis.
This will result in diurnal profiles of physical and chemical variables associated with tidal cycles
.- and precipitation events.
Bacteriological Analvsis
Water samples will be collected as above and transported to a lab for enumeration of enterococci.
Sediment Sampling
Sediment samples at each site plus a duplicate site will be collected annually (10 per year) using
a PVC core device. The top 5 cm of the cores will be analyzed in the SERC labs for a suite of
heavy metals using DEP Method MT-002-5: Microwave Digestion of soil, sediment, tissue, and
waste samples for total recoverable metal analysis and EP A Method 6020A: Inductively Coupled
Plasma-Mass Spectrometry; coprostanol using SERC-EARL-Standard Operating Procedure

Project: 1993-1996 Update, G.G. Lauenstein and A.Y. Cantillo (Eds), NOAA Technical
Memorandum NOS ORCA 130, Silver Springs, Maryland, (1998),
REPORTING
Reporting will include production of a geo-referenced station map, quarterly data reports, and an
annual interpretive report. The principal investigator will be responsible for ensuring the results
are compiled and the complete data set is submitted in a timely fashion to the Contractor.
Upon completion of the analysis of samples from each quarterly period, the principal investigator
will produce a statistical summary of the data in a logical format based on the station design.
The statistical summary will include calculated averages, sample variances, ranges, and number
of samples. When appropriate, the principal investigator will provide the summaries in a
graphical format. The principal investigator will submit a data and narrative report documenting
the results of each quarterly survey. The data report will include the raw data in SORET format
and statistical summaries in hard copy and on disc. The investigator will evaluate the data in
accordance with the data quality objectives developed in the QAPP.
After completion of analysis of samples from the fourth quarterly survey, the principal
investigator will produce statistical summaries of the data collection at each station to be
incorporated into an annual report. All data will be evaluated in relation to the data quality
objectives developed in the QAPP. The data will be analyzed using appropriate statistical tests
of significance to meet the specific objectives of the monitoring program.
COSTS
Costs for the Little Venice Water quality Sampling Program are estimated to be $363,000 for
four years of sampling (Phase 1 and 2) or $90,750 per year (Table 2). Total cost is based on the
following costs for analyses: salinity, temperature, and dissolved oxygen - $1.50 per sample:
total phosphorus and total nitrogen - $10.00 per sample: chlorophyll a - $5.00 per sample: suite
of nutrients - $15.00 per sample: fecal coliforms - $20 per sample; and enterococci - $25.00 per
sample. This includes analysis ofl0 sediment samples each year for heavy metals, pesticides,
and coprostanol at no charge to the project.
