INTRODUCTION
Ocean disposal of dredged materials can affect the environment of a disposal site by
disturbing the benthic community and potentially causing long-term reduction of oxygen in
the pore waters of the sediments and the overlying waters. Natural oceanographic
processes can also be responsible for transporting disposed materials offsite into nearby
habitats.
As part of Region 4's strategy to monitor the effects of dredged material disposal
within the marine environment, routine surveys of the benthos and water column within
and adjacent to our sites are conducted so that their status may be assessed. In addition,
the data is archived so that over time, trends which may occur can be observed. These
status and trends surveys are consistent with the requirements of 40 C.F.R. 228.9. The
present study being discussed was conducted aboard the Ocean Survey Vessel (OSV) Bold
on May 4-5, 2006.
BACKGROUND
The Savannah ODMDS was designated by EPA in 1987. The ODMDS has typically
received an annual average of over 900,000 cubic yards. The exception to those volumes
was during the deepening of the entrance channel from 1993-94, when volumes averaged
3 million cubic yards per year.
A Site Management and Monitoring Plan was developed for the Savannah ODMDS in
1997. Annual bathymetry surveys have been conducted at the site by the U. S. Army Corps
of Engineers. The first status and trends survey conducted at this site was in 1992.
Survey Area and Location
The study area is within and surrounding the Savannah, GA ODMDS located offshore
Tybee Island. The ODMDS is approximately 4.26 square nautical miles (nmi) in area.
Twelve stations were selected in order to analyze the sediment grain size, chemical, and
biological characteristics of two areas - one where disposal has occurred and the other one
undisturbed by disposal. Of these 12, one (1) station received water quality sampling.
Depths in this area average 37 feet. The ODMDS boundary corner coordinates are:
31°55'53"N 80o44'20"W
31°57'55"N 80°46'48"W
31°57'55"N 80°44'20"W
31°55'53"N 80°46'48"W
The ODMDS, survey area and station locations are shown in Figure 1.

METHODS AND MATERIALS
Method Rationale: Characterization of the benthic community and sediment size/chemistry at
selected stations, followed by analysis of community parameters via statistical treatment,
allows for identification and interpretation of changes in the community structure. Such
community statistics can be used to draw inferences regarding perturbations to the benthic
macroinvertebrate community and subsequently allow for judgments regarding the
likelihood of impact from dredged material disposal.
Sampling Stations
The boundaries of the Savannah ODMDS measure approximately 2X2 nmi. Twelve
stations (see Table 1 and Figure 1) were established by selecting half within and half
outside of the site, which provides two treatments with 6 replicates/treatment. Station
locations were selected by a stratified, random method.
Water Quality
To characterize the general water quality associated with the dump site, the following water
column parameters were sampled: conductivity, dissolved oxygen (DO), salinity,
temperature, density, turbidity, % light transmission and Chlorophyll a.
All measurements were collected utilizing the ship's CTD. Go Flow® bottles attached to the
CTD/rosette frame were tripped at the bottom and near the surface to obtain water
samples for the laboratory analysis. Once the rosette was back aboard the ship, the bottles
were emptied directly into the appropriate sample containers, labeled, and refrigerated until
demobilization. Laboratory analyses of the water include nutrients, metals, PAHs, PCBs and
pesticides. In addition, one other sample container was filled with bottom water and
analyzed for dioxins.
Sea floor Sampling
Bottom sampling at all twelve stations was accomplished by a minimum of two deployments
of a Young grab (surface area = 0.04 m 2; depth of 10 cm) from the stern of the ship.
After retrieval of the grab and confirmation of an adequate sample, the device was either
sub-sampled in order to obtain discrete samples for sediment particle size analyses and
sediment chemical analyses, or used entirely for benthic macroinvertebrate identification.
The sampling device and handling/preservative protocol for each type of sample follows
below:
Sediment Particle Size
Two separate samples for particle size were collected from the Young grab by acrylic
5 cm diameter coring tubes. The subsamples were placed into whirl packs, labeled, and
frozen for return to the lab. The samples were analyzed by subcontractor utilizing a wet
sieve method (see Vittor, 2007).
-------
•: .¦ •/' ' ¦ JVl ' ''x% »
Sediment Chemistry
Analyses for the following parameters were conducted at the SESD lab in Athens,
Georgia: heavy metals scan, nutrients which includes total phosphorous (TP), N02+N03,
NH3, and TKN, extractable organic compounds, pesticides, and PCBs. The sample was
transferred to a glass pan and thoroughly mixed. The sample was alloquated into two
236.6 ml. glass containers and preserved by storing at 4 C until analyzed. One container
was analyzed for extractable organic compounds and the other was analyzed for metals and
nutrients. In addition, at stations SA04, SA07, SA08 and SA12, one additional container
was filled from the sample and analyzed for dioxins. The limited number of dioxin samples
were due to budgetary constraints.
Benthic Macroinvertebrate Infauna
Sediment from a separate deployment of the grab were collected to obtain benthic
macroinvertebrate organisms. On-board processing involved washing the sample through a
#35 screen (0.5mm). The sample retained on the screen after washing was preserved in
10% seawater formalin with staining solution. Benthic containers were labeled both
internally and externally and stored for transfer to contract lab facilities. The details of
sorting and identification of infaunal taxa are described in Vittor, 2007.
All sampling procedures and sample preservation for analyses were according to the SESD
Standard Operating Procedures (SOP), (US EPA 1996, 2002).
RESULTS AND DISCUSSION
Water Quality
The results of the water quality profiles are summarized in Table 2. In general, the
narrow range of values seen within the data demonstrates the well-mixed nature of the
ODMDS's water column.
Turbidity ranged from 0.55 to 1.06 NTUs, while dissolved oxygen (DO) readings
ranged from 6.50 mg/L to 6.84 mg/L (see Table 2 and Figure 2).
Temperature and salinity profiles also showed that the waters within and around the
Savannah ODMDS are very well-mixed. Temperatures ranged from 20.93 to 21.57 oc;
salinities ranged from 31.37 to 32.58 ppt (see Table 2 and Figure 3).
Chemical analyses of the water samples collected as part of this study showed all
analytes to be at or below the detection limit with the limited exceptions of arsenic, copper
and a few of the least problematic dioxin congeners (see Appendix D).

Sea floor Sampling
Sediment Particle Size.
The results of the sediment particle size analyses are given in Table 3. In general,
all stations were found to be predominantly sand with small amounts of gravel and silt/clay.
The two most notable exceptions were Stations SA01 and SA06, which both had more than
16% gravel.
Sediment Chemistry.
The sediment chemistry showed nearly all contaminants to be below detection limits
with the notable exception of ten metals (see Table 4) and a variety of dioxin congeners.
Because the average concentration for stations from within the ODMDS was consistently
lower than the average concentration for stations from outside the site, for all metals, a test
for statistical difference between these two treatments was deemed unnecessary.
The results of dioxin analyses are provided in Appendix C. Although several dioxin
congeners were detectable across the four sediment stations, no distinctive pattern can be
discerned, either within the two stations inside the ODMDS or outside the ODMDS. The
most notable pattern found within the data seems to be the relatively higher concentrations
found at SA07, which did have 4-5 times the amount of silts and clays found at the other
three stations analyzed for dioxin. Despite the substantially higher silt/clay fraction found
at SA07, it still did not average more than 2.8 % of the total sediments for that station.
Benthic Macroinvertebrate Infauna.
The benthic infauna data is detailed and summarized in "Savannah, Georgia ODMDS
2006 Benthic Community Assessment "(Vittor, 2007). Polychaetes dominated the total
assemblage (60.3%), and also ranked first in number of taxa (54.7%) represented. In
terms of abundance, the polychaetes were followed by malacostracans (9.1%) and bivalves
(8.0%): by taxa, the polychaetes were followed by malacostracans (19.3%) and bivalves
(10.0%).
The dominant taxa found outside the ODMDS were the polychaete, Spiophanes
bombyx(9.B>0/o), the chordate, Branchiostoma [LPIL] (8.6%) and the bivalve, Crassineiia
iunuiata (5.5%). Inside the ODMDS, the dominant taxa were the polychaete, Spiophanes
bombyx(20.2%), the polychaete, Spio pettiboneae (6.9%), the amphipod, Rhepoxynius
hudsoni (6.7%), the bivalve, Tel Una [LPIL] (5.7%), the cumacean, Oxyurostylis smithi
(5.2%) and the polychaete, Mediomastus californiensis (5.1%).
Mean densities ranged from 1175 organisms/m2at Station SA05 to 31000
organisms/m2 at Station SA01. Although densities averaged 9950 outside the ODMDS
-------
•: .¦ •/' ' ¦ JVl ' ''x% »
compared to 3687.5 inside the ODMDS, there was not a significant difference in densities
between stations inside vs. outside (Vittor, 2007).
The mean number of taxa ranged from 21 taxa/station at Station SA05 to 61
taxa/station at Station SA01. Again, although taxa richness averaged 42.5 outside the
ODMDS compared to 34.8 inside the ODMDS, there was not a significant difference in mean
number of taxa between stations inside vs. outside (Vittor, 2007).
The results of cluster, ANOSIM and SIMPLER analyses are discussed in detail within
Vittor, 2007. In summary, these results indicate that assemblages inside and outside the
ODMDS are similar. Table 5 lists the infaunal community parameters by station.
CONCLUSIONS
When comparing the various study parameters between stations located within the
ODMDS and those outside the ODMDS, no significant differences can be found. Table 6
summarizes the main parameters of this study, demonstrating that no physical, chemical
nor biological difference can be seen.
