1.0 INTRODUCTION
Three Oaks Engineering retained Eaton Scientific, LS to conduct benthic macroinvertebrate
(benthos) surveys as part of the National Pollutant Discharge Elimination System (NPDES)
permit requirement for Bay Valley Foods near Faison in Duplin County,North Carolina. The
project evaluated six sites. Benthic macroinvertebrate community surveys were conducted at
two sites in Panther Branch(Sites 1 and 2) and three sites in Goshen Swamp (Sites 3, 5, and 6).
Only water quality data was collected for Site 4 (Figure 1). Panther Branch and Goshen Swamp
are tributaries of the Cape Fear River and are located within USGS Hydrologic Unit Code
(HUC) 03030007.
2.0 SITE DESCRIPTIONS
Collections of benthic macroinvertebrates were made from five sampling locations: Site 1, 2, 3,
5, and 6 (Appendix A, Figure 1). See Appendix C for site photos.
Site 1. Site 1 is the most upstream site located on Panther Branch along NC 50. The stream was
located near a residence and active farm. At the time of the survey, the wetted width of the
channel was approximately 7 m, with a water depth mostly greater than 1.5 m. No flow was
observed in this reach despite normal flow levels at nearby stream gages. The aquatic habitat
consisted mainly of a long pool with wooded wetlands in the adjacent floodplain. Substrate was
composed of mainly sand and silt. Aquatic vegetation was present in backwaters and as a
narrow band at the stream edge. The riparian buffer consisted of wetlands on both sides of the
stream. Vegetation included mature trees, shrubs, herbs, and grasses. Mosquitofish(Gambusia
holbrooki) and a Bluespotted sunfish(Enneacanthus gloriosus)were collected and released. The
meiofauna Daphnia and Nematoda were observed but not collected.
Site 2. Site 2 is located approximately 2.3 kilometers(kin) downstream of Site 1 on Panther
Branch just off of the 1-40/US 117 connector and below the discharge of the Bay Valley pickle
processor. The stream was flowing swiftly through this reach of Panther Branch and the channel
had some sinuosity. Stream wetted width was approximately 4 m and the water depth ranged
from approximately 0.4-0.8 m. Flow conditions were normal. Stream habitat consisted of a
riffle/pool/run sequence with a substrate composed almost entirely of sand. There was a good
amount of aquatic vegetation, sticks and snags. In contrast to Site 1,the riparian zone at Site 2
was comprised mostly of grasses with small trees providing partial canopy cover in the utility
easement. An empty hydroptilid case was collected and Daphnia and Cladoceran meiofauna
were observed but not collected.
Site 3. Site 3 is the most upstream sampling site on Goshen Swamp along NC 50. Stream
wetted width ranged from 35-50 m and stream depth was beyond wader depth(approximately
1.5 in) in all but edge areas. No flow was observed. Silt was the dominant substrate here with
some sand throughout. Stream habitat consisted of snags and small patches of aquatic
vegetation. The riparian buffer was mature and extensive with minimal canopy cover over the
large,'main channel. Meiofaunal Daphnia were abundant here,but\not collected.

Eaton Scientific 1

Site 4. Site 4 is located approximately 3.1 km downstream of Site 3 on Goshen Swamp along I-
40/US 117 connector. Only water quality data was collected at this Site(Table 2). No habitat
information was recorded.
Site 5. Site 5 is located approximately 1.3 km downstream of Site 4 on Goshen Swamp just off
of US 117. Fresh deposits of sand, approximately 10-20 cm deep, covered most of the flood
plain, likely from hurricanes Florence and/or Michael. Stream wetted width was about 12 m.
The water depth ranged from approximately 0.8-1.4 m. Stream habitat consisted of ample
aquatic vegetation and snags in good flowing run habitat with several pools. The substrate was
composed mainly of sand with smaller amounts of silt. The riparian buffer zone here was wide
with a mix of small and mature trees giving the stream about a 70% canopy cover. Shells of
Elliptio complanata and Uniomerus carolinianus were observed but not collected as were the
meiofauna Daphnia, Collembola, and Nematoda.
Site 6. Site 6 is the most downstream site of Goshen Swamp on NC 403. The wetted width was
approximately 12-18 m with water depth ranging from 0.5-1.5+m once one moved far enough
away from the bridge pool. Flow slow to moderate with habitat consisted of aquatic vegetation
along the margin and snags in flow. The riparian buffer was wide, consisting of a mix of young
and mature trees and shrubs, once again, with heavy deposits of sand, including sharks' teeth.
Vertebrates seen, but not collected, included a turtle and a water moccasin, while the meiofauna
Daphnia and Collembola were also seen, but not collected.
3.0 METHODOLOGY
3.1 Benthic Macroinvertebrate Sampling
The benthic macroinvertebrate surveys were conducted for Sites 1,2 and 3 on March 13, 2019 and
Sites 5 and 6 on March 14, 2019. Water chemistry information was collected from ite 4 on
March 14. Collections were made by Larry Eaton(Eaton Sci),Tom Dickinson(3 Oaks), and
Lizzy Stokes-Cawley(3 Oaks).
3.1.1 Field Methods
Water quality monitoring programs have been implemented by NCDWR to assess water quality
trends in North Carolina. One method used is the monitoring of benthic macroinvertebrates, or
benthos, to assess water quality by sampling the aquatic community. The species richness and
overall community tolerance to stress, as well as the presence of various groups intolerant of
water quality degradation, are reflections of water quality.
Sites were sampled utilizing the NCDWR Swamp method described in the NCDWR's Standard
Operating Procedures for Collection and Analysis of Benthic Macroinvertebrates, Version 5.0
(NCDENR 2016). Qualitative collections of aquatic macroinvertebrates were made with aquatic
dip nets, 300 micron midge collectors, and hand picking organisms from substrates. A multiple
habitat approach was used,where specimens from all available habitats(stream margins, leaf packs,
aquatic vegetation, detritus, woody debris and logs, and sand accumulations) are combined to
form one aggregate sample. Macroinvertebrates were sorted from detritus and preserved in the
field with 90% ethyl alcohol.

3.1.2 Water Chemistry
Water chemistry was measured at each site in conjunction with benthic macroinvertebrate sampling.
Parameters measured were temperature, dissolved oxygen(DO), specific conductivity, and pH
(Table 2).
3.1.3 Sample Processing
Eaton Scientific, LS, a North Carolina certified laboratory(North Carolina Certification#043),
identified the benthic macroinvertebrates collected to the lowest practical taxonomic level with
microscopic techniques and taxonomic keys(Table 1,Appendix B). Habitat Assessment Field
Data Sheet for Coastal Plain Streams were completed for each sampling site (Appendix D).
3.1.4 Data Analysis
Analysis of, and comparison between,the benthic macroinvertebrate communities at each site were
determined with established indices and metrics described in the Standard Operating Procedures
for Collection and Analysis of Benthic Macroinvertebrates, Version 5.0. (NCDENR 2016). The
metrics used in this evaluation of swamp sites in DWR Swamp Area A to assign bioclassifications
included the total taxa richness,Ephemeroptera,Plecoptera and Trichoptera(EPT)taxa richness,
DWR Habitat Score, and NC Biotic Index(BI) (Tables 1 and 3). The primary output was a taxa list,
with species totals and a record of each taxon's relative abundance.
Total taxa,EPT(Ephemeroptera+Plecoptera+Trichoptera)taxa richness, and the BI values were
compared between sites.These metrics are based on the idea that unstressed streams and rivers have
many invertebrate taxa and are dominated by intolerant species. Conversely,polluted or otherwise
stressed streams have fewer numbers of invertebrate taxa and are dominated by tolerant species.
The diversity of the invertebrate fauna is evaluated using taxa richness counts. The tolerance of the
stream community is evaluated using a BI. In general,higher EPT taxa richness values and lower
BI values usually indicate better stream quality. BI ratings range from 1-10 with a score of 1
generally reflecting high stream quality based on benthic macroinvertebrate diversity and habitat
availability while a higher score generally reflecting a stream receiving greater stress.

4.3 Habitat Assessment Scores
Habitat scores were determined using the Habitat Assessment Field Data Sheet for Coastal Plain
Streams and are shown in Table 3. These visual-based habitat evaluation scores consist of seven
parameters that rate channel modification, instream habitat,bottom substrate,pool variety,bank
stability and vegetation, light penetration, and riparian vegetation zone width for each sampling
reach. A numerical score is used to rate each parameter and the total score gives a relative
measure of overall habitat quality(Appendix D).

5.0 DISCUSSION/CONCLUSIONS
The benthic macroinvertebrate communities seem to be driven more by the presence or absence of
flow than potential impairments from the discharge. The two sites that had no visible flow,Panther
Branch 1 and Goshen Swamp 3,were rated Severely Stressed,while the three sites with flow,
Panther Branch 2, Goshen Swamp 5 and Goshen Swamp 6,were all rated Moderate Stress. The
only indications that there may be an impact from the discharge was that Panther Branch below the
outfall was rated Moderate with 5 points, a Biotic Index of 7.47 and no stoneflies,while the lower
Goshen Swamp sites were rated Moderate with 6 points, a Biotic Indices 0.2 lower(7.26)with one
stonefly(Perlesta). These differences are likely too small to be significant.
While possibly not germane to the question of Bay Valley discharge impacts on Panther Branch and
Goshen Swamp, it is worth noting abnormally high pH and DO values(for non flowing swamp
systems). Swamp systems in North Carolina are defined as systems with low pH and DO,however
the 8.5 pH and 9.3 mg.l DO recorded at Panther Br 1 is elevated to the point of indicating an algae
bloom(NCDENR 2013b). Algae blooms require two things, sunlight and excess nutrients. The
sunlight part of bloom conditions here must include the lack of buffer on the stream just above the
road,where the farm mows its large lawn right down to the water's edge,providing ample direct
sunlight. The source of nutrients is not so obvious. It could be runoff from the well manicured
lawn or it could be coming from one of the many fields in the watershed.Whatever the source,the
effects of the algae bloom upstream on Panther Branch might be difficult to tease apart from any
potential impacts from the discharge.
Conductivity, a measure of the number of ions in the water, is the best chemical metric for tracking
the effects of the ions from the Bay Valley brine discharge. While the below-discharge(Panther Br
2)conductivity value of 506 µs/cm is high for water in North Carolina not associated with tides,it is
still far lower than values recorded here in the 1980s,when pickle plant discharge studies collected
brine flies. The good habitat and good flow at this site appear to offset much of the stress from the
high conductivity. There does appear to be a slight increase in conductivity in Goshen Swamp
related to the discharge,increasing from 145 pS/cm at Sites 3 and 4 above Panther Branch to 192 at
Site 5 below the confluence.'Since there was essentially no difference in the aquatic communities
of Goshen Swamp sites 5 and 6 (BI 7.26 at both sites)even though conductivity at Site 6 had
dropped to 174,it does not appear that small changes in conductivity in Goshen Swamp had much
impact on the invertebrate community.
