INTRODUCTION
REPORT PURPOSE
This report has been prepared to provide interested parties with general information
regarding the Middle Cape Fear River Basin Association’s activities during calender year
2004. The report describes the Association’s organizational structure, financial position,
current, and future monitoring and research activities. This report also includes a
summary of the current water quality findings for the middle Cape Fear River Basin.
I.B.
BACKGROUND
The middle section of the Cape Fear River stretches from NC 42 near Moncure to Lock
and Dam number 1 near Riegalwood. It includes approximately 2000 square miles of
drainage basin and approximately 2700 miles of perennial streams (approximately 22%
of the land and stream miles in the Cape Fear River Watershed). The area of study is
highlighted in red in Figure 1.
Figure 1
Prior to July of 1998 the water quality data that was being collected in the middle section
of the Cape Fear River was sporadic, uncoordinated, and lacked adequate collection
protocols to ensure data quality. Municipal and industrial wastewater dischargers did
most of the sampling and data collection as part of their NPDES permit requirements.
Each entity was responsible for ambient data collection upstream and downstream of
their respective discharge. Parametric coverage was usually minimal, including basic
field measurements and occasionally BOD, Fecal Coliform, Ammonium, and specific
metals. The sampling usually occurred from the bank of the river or stream rather than
mid-stream, and frequently resulted in data that was not representative of the true
condition of the water body.
1
In 1997, a coalition of dischargers in the middle section of the Cape Fear River
approached the North Carolina Division of Water Quality (NCDWQ) with a request to
implement a more comprehensive water quality monitoring program in the middle Cape
Fear River in exchange for a waiver of the ambient monitoring requirements in their
NPDES permits. NCDWQ agreed to the request and in July of 1998 the Middle Cape
Fear River Basin Association’s water quality monitoring program was initiated.
Members of the MCFRBA signed a Memorandum Of Agreement with the NCDWQ
binding them with participation in the monitoring program. If a member withdraws from
the Association their upstream & downstream ambient monitoring requirements in their
NPDES permit immediately go back into effect.
Aqua Tech Environmental Laboratories of Sanford, NC conducted the first three years of
the monitoring. In the spring of 2001, the Association re-competed the monitoring
project and a new contractor, SIMILABS of Burlington, NC was awarded the project.
SIMILABS (recently purchased and now known as Pace Laboratories) took over the
project in July 2001. In the Spring of 2004 the MCFRBA began experiencing problems
with Pace and their contract was not renewed. The MCFRBA entered into negotiations
with several labs and ultimately selected Meritech as the new contractor. Meritech began
collecting and analyzing the samples in July 2004.
In addition to the ambient monitoring program, the Association has initiated several
research projects to gain a better understanding of the forces driving water quality in the
Middle Cape Fear River. These projects include a clean metals study, a continuous water
quality monitoring station at Lock & Dam number 3 (parametric coverage including
dissolved oxygen [DO], pH, temperature, and conductivity), two studies to better
characterize algal productivity with nutrient influences in the mainstem of the Cape Fear
River, a sub-basin assessment of a 303(d) listed stream in Cumberland County, and a
fecal coliform study of Cross Creek in the Fayetteville area. Summaries of these projects
are included in Section III.B of this report.

ORGANIZATIONAL INFORMATION
The Middle Cape Fear River Basin Association is a legal, non-profit organization, which
was incorporated in the spring of 1998. The purpose of the Association is to better
understand the processes that influence water quality in the Cape Fear River. The
primary goals of the Association are to:
•
•
•
Maintain a stakeholder coalition
Implement a comprehensive water quality monitoring program, which provides key
data for specific water quality management decisions
Encourage effective water resource management strategies
The Association is governed by its Board of Directors, which includes one representative
from each dues paying member. The Board of Directors has ultimate responsibility for
all financial actions, membership, election of officers, and decisions affecting the
coalition.

The Association formed a Technical Committee to plan and implement the ambient
monitoring program and special research projects. The Technical Committee meets
approximately every other month to review current projects, to plan future activities, and
to make recommendations for action to the Board of Directors.
Technical Committee members represent a broad range of stakeholders with expertise in
water quality research and management issues and they serve on a volunteer basis. The
Technical Committee is open to participation to anyone that would like to attend. The

AMBIENT MONITORING PROGRAM
III.A.1
MONITORING PROGRAM DESCRIPTION
The Middle Cape Fear River Basin Association (MCFRBA) has entered into a
Memorandum of Agreement with the NC Division of Water Quality (NC DWQ) to
conduct the upstream/downstream monitoring required by its members’ NPDES permit.
This monitoring began in July of 1998 and will continue as long as the coalition remains
active.
The current monitoring program required by the MOA for the middle Cape Fear River
(CFR) includes twenty-four stations, which were established in cooperation with the NC
DWQ to monitor water quality near point source discharges. In addition, the MCFRBA,
in cooperation with NC DWQ, has added an additional six monitoring stations at strategic
locations in the middle Cape Fear River Basin to gather data that is more comprehensive
in nature. Water quality samples are analyzed on a regular basis for a range of
parameters including temperature, dissolved oxygen, conductivity, pH, total phosphorus,
ammonium, nitrite-nitrate, TKN, and metals. All monitoring data collected as part of this
program is submitted to NCDWQ on a regular basis and is also compiled in a database
that is available to MCFRBA members, Cape Fear River Assembly, and others as
requested.
Several changes were made to some of the detection levels in the MCFRBA MOA in
June 2004. These changes are discussed in greater detail in Section IV.B of this report.
Sample stations are located throughout the middle section of the Cape Fear River and the
coverage includes the main stem of the river as well as most major tributaries. Figure 2 is
a list of station locations, and Figure 3 lists parametric coverage for each station. Station
maps are found in Appendix D.

SUMMARY OF 2004 AMBIENT MONITORING DATA
The following sections summarize the results of the data collected from the January to
December 2004. For the purpose of this summary the data has been grouped into three
areas, Upper Middle CFR, Central Middle CFR, and Lower Middle CFR. Upper Middle
CFR is the area above Fayetteville and includes sub-basins CFP07, CPF13, and CPF14.
The Central Middle CFR includes the Fayetteville metro area to above Lock & Dam #3
and includes sub-basin CPF15. The Lower Middle CFR includes the area from the
headwaters of Lock & Dam #3 to Lock & Dam #1 and includes sub-basin CPF16.

Streams were rated as Good, Fair, or Poor based on compliance with the water quality
standards for dissolved oxygen, fecal coliform, turbidity, chlorophyll a, and metals.
Stations with 0 % to 10 % violations were rated as Good, 11 % to 25 % Fair, and greater
than 25% Poor.
III.A.2.1
Dissolved Oxygen (DO)
Overall there were no significant dissolved oxygen problems in the middle section of the
Cape Fear River in 2004 (Figure 5). In the Upper Middle and Lower Middle CFR there
were no recorded exceedances of the instantaneous DO standard of 4 mg/l. In the Central
Middle Cape Fear River the chart indicates 17% of the stations had a rating of poor.
However, these exceedances all occurred at one station, B7700000, which is Rockfish
Creek at SR1432. This area is heavily influenced by swamp drainage.

Fecal Coliform
Fecal coliform levels were assessed by comparing the geometric mean of the data
collected to the water quality standard of 200 colonies per 100 milliliters, and comparing
the raw data to see if more than 20% of the data points exceeded the water quality
standard of 400 colonies per 100 milliliters. If either of these criterion was exceeded the
water quality at that station was considered poor. There were no fecal coliform problems
in either the Upper Middle or Lower Middle Cape Fear River. However, in the Central
Middle Cape Fear River 50% of the stations rated as poor for fecal coliform (Figure 6).
In 2004 fecal coliform was elevated at stations B7500000 (CFR at I-95 By-Pass),
B7700000 (Rockfish Creek at SR1432), and B7590000 (Cross Creek at US 301).

area. The stations are B6160000 (CFR above Buckhorn Dam), B8290000 (CFR above
L&D #3), B8305000 (CFR SR1316), B8339000 (CFR above L&D#2), and B8349000
(CFR above L&D#1). Figure 8 shows that 20% of the stations were rated as poor for
chlorophyll a. However, these exceedances all occurred at one station, B6160000, which
is the CFR above Buckhorn Dam.

Metals
Metals are collected at five stations in the Middle Cape Fear River Basin’s sample area.
These stations include B6370000 (CFR at US 401 in Lillington), B6840000 (CFR at NC
217 at Erwin), B7500000 (CFR at I95 By-Pass below Fayetteville), B8290000 (CFR
above L&D #3), and B83490000 (CFR above L&D #1). Data comparisons were made to
the North Carolina water quality standards and action levels. There were no exceedances
of the water quality standard for Pb, Ni, Cr, Cd, Mn, Hg, or As. The action level was
exceeded for Cu, Zn, and Fe quite frequently at several stations (Figure 9). For Al, the
Federal criterion was used, however, the State of North Carolina has not yet adopted the
Federal standard.

LONGTERM TRENDS
The following sections summarize the long-term trends of the data collected during the
July 1998 to December 2004 time period and conclusions that have been reached from
this analysis.
III.A.3.1
Dissolved Oxygen (DO)
Average DO saturation above Buckhorn Dam and Lock & Dam #3 is consistently
elevated. The Chlorophyll a (Chl. a) data suggests this is due to photosynthetic activity.
The Chl. a levels above Buckhorn Dam are higher than would typically be expected in a
river. Average summer values were 19.7 and 24.1 ug/l behind Buckhorn Dam and Lock
& Dam #3, respectively (Fig. 10) in the ’99 through ’04 period. Chl a levels show a high
negative correlation with elevated DO saturation at these stations.

River Mile
Figure 10
The trend analysis shows DO levels in the section of the river below Lock and Dam #3
tend to be relatively low. While the “average” DO values for the entire stretch were
above the 5 mg/l water quality standard (Figure 11), the “minimum” values were often
below the 5 mg/l daily average standard and in several instances dipped below the
instantaneous standard of 4 mg/l (figure 12).
In 2001, Dr. Don Francisco conducted an evaluation of Sediment Oxygen Demand
(SOD) data collected by NC DWQ, Long Term BOD data, and the NPDES discharger’s
data. Based on the available information, the calculations of BOD loading do not account
for the amount of oxygen demand being exerted on the system. Part of the problem could
be elevated turbidity levels, which will reduce photosynthesis, thereby reducing oxygen
inputs into the system.
13
It has also been noted that during low flow conditions there is very little current in the
river. Below the confluence of the CFR and Rockfish Creek the river basin narrows
considerably and there is relatively little input from tributaries. It has been hypothesized
that since there doesn’t appear to be enough BOD loading to account for the oxygen
demand being exerted, but the DO is still low in the river, the re-aeration rate must also
be low. Therefore, the low DO values are not likely due to a large oxygen demand, but
more likely due to a slight increase in oxygen demand combined with very low reaeration rates, which is not atypical for a low-slope river in the coastal plain.

Two tributaries frequently exhibit low DO conditions. Lick Creek and Buies Creek were
often below the instantaneous DO standard of 4 mg/l (Figure 13). The Buies Creek
station was moved in July 2003 due to problems obtaining a representative sample. The
new station has recorded no violations of the water quality standard for DO. There are no
known point source discharges upstream of these sample stations, therefore the low DO
levels are the result of non-point sources or natural conditions. Neills Creek, Rockfish
Creek, and Turnbull Creek also exhibited some low DO conditions.

Figure 18
A detailed watershed analysis is needed to determine the relative contributions of nutrient
sources. 1The nutrient data suggests that the Total Nitrogen to Total Phosphorus ratio
(TN:TP) is widely variable from year to year (Figure 19). Investigations conducted by
Dr. Steve Whalen at UNC Chapel Hill demonstrate that the system is neither limited by
TN or TP, but rather limited by light penetration and detention time. A trend analysis of
Chlorophyll a verses turbidity and flow seems to verify these findings. Figure 20 shows
a strong relationship between flow, turbidity, and Chlorophyll a levels.
1
TN:TP Ratio calculated using the Redfield Ratio, which was developed by measuring C:H:O:N:P in a
sample of algae. The N:P ratio was about 7.0 –7.5:1 (weight). Redfield assumed that if the concentration
of the nutrient present in the environment was at that ratio, the supply was balanced to the demand. It
should be noted that this is just an indicator of nutrient conditions and not a firm law.

Figure 21 shows this trend in more detail. This graph demonstrates the relationship
between flow, turbidity, and Chlorophyll a at station 14 (above L&D #3) for the summer
months of 2000, 2001, 2002, 2003, and 2004. The chart shows that as river flow
increases, the Chlorophyll a levels decrease. Conversely, as river flow decreases
Chlorophyll a levels increase.

Figure 21
When Tn and TP are added to the graph there is no strong relationship between nutrient
load and Chlorophyll a levels (Figure 22). This is particularly clear in the instances
where TP and TN loads rise with the flow in the river and there is a corresponding
decrease in Chlorophyll a levels. Higher flows mean more input into the river from the
watershed. It also means higher turbidity, which equals lower productivity, which equals
a lower demand for nutrients.

which is located on the CFR at US401, shows an upward trend in TN and TP loading
(Figures 23 & 24). However, this trend appears to be heavily influenced by the January
to July ’03 time period, which corresponds to near record rainfall and stream flows.

The drainage area above Lock & Dam #3 is much larger, accounting for about 70%
percent of the overland flow that enters the middle section of the CFR. Below the
Rockfish Creek WRF the drainage basin narrows and there is relatively little tributary
input that reaches the mainstem. In addition to a proportionally larger drainage area,
most of the urban development is located in the upper portion of the middle CFR, which
could account for the higher fecal counts.

pH
Several stations have exhibited low pH since the inception of the monitoring program
(Figure 37). The low pH readings do not appear to be related to point source discharges
and are probably related to natural conditions such as swamp drainage.

AMBIENT DATA SUMMARY
The data collected from July 1998 through December 2004 indicates chlorophyll a,
dissolved oxygen, and fecal coliform are the most problematic parameters of concern in
the middle Cape Fear River basin. Above Buckhorn Dam and Lock and Dam #3 the
dissolved oxygen levels appear to be heavily influenced by algal productivity, which is
validated by the elevated Chlorophyll a levels and episodes of dissolved oxygen super
saturation. Low flow conditions tend to create a backwater effect behind the dams
causing the system to respond like a series of lakes. This allows algae sufficient time to
reproduce and utilize the abundant nutrients in the system and as a result the DO levels
fluctuate significantly.
Algal productivity does not appear to have the same effect in the lower section of the
river from Lock & Dam #2 to Lock and Dam #1. In fact, during the last five years the
MCFRBA has not recorded a single Chlorophyll a value that exceeded the water quality
standard of 40 micrograms per liter at station 25, which is just above Lock & Dam #1 at
Riegelwood. The low DO levels in this part of the river are likely the result of BOD load
and swamp drainage combined with a very low re-aeration rate. A TMDL is currently
being developed for dissolved oxygen in the Cape Fear River estuary, which begins
immediately below L&D #1. Depending on the results of the modeling for this TMDL
this issue could become a larger issue in the future.
Cross Creek has the highest fecal coliform counts of all of the stations in the Middle Cape
Fear River Basin. This stream runs through downtown Fayetteville. The annual
geometric mean for 1999, 2000, 2001, 2002, 2003, and 2004 was 406, 266, 184, 536,
654, and 236 respectively. The Middle Cape Fear River Basin Association is searching
for ways to try to identify the fecal source. An infrared aerial survey was conducted in
early March of 2004, all potential hot spots identified in the infrared survey were visited
in the fall of 2004, and a two-month intensive sampling regime was conducted in January
to March 2005. Results from this sampling are still being evaluated, however one of the
27
tributaries, which drains the western side of the Cumberland County Landfill exhibited
significantly higher fecal counts than the other sampling stations.
Metals don’t seem to be an issue of concern anywhere in the middle Cape Fear River.
For lead (Pb), chromium (Cr), cadmium (Cd), mercury (Hg), and arsenic (As), there were
no detected exceedances of the Water Quality Standard during the July 98 through
December 04 time period. Nickel (Ni) exceeded the standard in 6% of the samples at
stations #5 and 25, Copper (Cu), zinc (Zn), iron (Fe), and aluminum (Al) (EPA criterion)
exceeded the Action Level on a fairly regular basis, however these metals are common
constituents for this geologic region and it is not unusual to see these levels in the water
column. It should also be noted that the State of North Carolina has not adopted an
action level or water quality standard for aluminum. A summary of the data collected
using clean methodologies is included in Section III.B.3 of this report.
A summary of the frequency of exceedance of the Water Quality Standards/Action levels
is provided in Figure 38.

RESEARCH & SPECIAL PROJECTS
III.B.1.
WATER QUALITY EVALUATION BEHIND LOCKS & DAMS
In 1999, the MCFRBA contracted for a study of the influence of the Lock and Dam
system on water quality in the Cape Fear River. Steve Whalen, UNCCH, and PV
Sundareshwar, Duke University conducted the research. The overall goal of the project
was to assess the impact that each lock and dam has on downstream river water quality,
in particular the effect on dissolved oxygen levels and productivity of algae. The full
reports of the projects are available upon request.
III.B.2
NUTRIENT REDUCTION EVALUATION
For the past three years Steve Whalen and Lindsay Dubbs have been conducting
experiments in laboratory mesocosms to empirically evaluate the impact of nutrient
reduction on water quality in the Middle Cape Fear River. They have evaluated the
effect of reduced nutrients on phytoplankton biomass (chlorophyll a), primary production
(14C uptake) and community composition. The final report has yet to be published but a
summary of the findings is available upon request.
III.B.3
CLEAN METALS
The Clean Metals Study was initiated due to concerns about accuracy of some analytical
methodologies at very low detection levels, which are typically found in streams, lakes,
and rivers in our geographical area. The parameters of concern included Mercury,
Cadmium, Chromium, Copper, Nickel, Lead, and Zinc. The results of the study showed
that significant differences in conclusions can be drawn when analytical methods are
employed where the detection levels are below the level of concern. In this study, the
clean results generally indicated lower metals levels and less variability in sample results.
A copy of the full report is available upon request.
Additionally, the MCFRBA began using clean metals methodologies on all samples
collected as part of the ambient monitoring program in July 2003. In Figure 39 is a
summary of the data collected during 2004 using the clean methodologies. There were
no samples that exceeded any Water Quality Standards. Notably, all of the Mercury
samples were well below the standard of 0.012 mg/l. Copper, Zinc, Aluminum, and Iron
exceeded the Action Level occasionally, however, it is not unusual to see these metals at
these levels in this geographic area of North Carolina.
The MCFRBA initiated a rigid QA/QC protocol for the clean metals analysis beginning
in July 2003. Unfortunately, Pace Laboratories was unable to meet the requirements
established by this protocol. As a result, the protocol was not fully implemented until the
sampling program was taken over by Meritech in July 2004. QA/QC data is tabled in
Figures 40, 41, and 42.

III B.4
CONTINUOUS MONITORING STATION & L&D 3
In June of 2000 the Middle Cape Fear River Basin Association, in cooperation with the
US Geological Survey (USGS), installed a continuous monitoring station above Lock &
Dam #3 on the Cape Fear River. This station was in operation through December 2003
and collected continuous real-time water quality data for dissolved oxygen, temperature,
pH, and Conductivity. The data is available upon request.
III.B.5
LITTLE CROSS CREEK BMP STUDY
The Middle Cape Fear River Basin Association, in cooperation with the Public Works
Commission (PWC) of the City of Fayetteville, is working to install retrofit BMPs in the
Little Cross Creek watershed. Previous water quality investigations have raised concerns
regarding inputs of suspended sediment, phosphorus, and bacteria from non-point sources
in the watershed.
The first phase of this effort resulted in a list of watershed improvement projectsA total
of 98 potential projects were identified. The estimated capital cost for these projects is
approximately $16 million and these projects would reduce estimated loads of suspended
sediment from the watershed by about 50%. However, the top 35 projects will achieve
approximately 35% of the sediment reduction for a capital cost of about $7.5 million.
The Public Works Commission has submitted a grant application to the Clean Water
Management Trust Fund to implement five of the BMPs identified in the study. The
CWMTF has approved $766,000 in funds for the design, engineering, and property
acquisition for these five projects. PWC has entered into an agreement with CH2M Hill
for engineering services to design the projects. Design has begun on the project and
acquisition of property is underway. Additional information is available upon request.

QA/QC ISSUES & MONITORING EXCEPTION REPORT
Pace Analytical Services, Inc (formerly SIMALABS International) performed sampling
and analytical requirements of the Memorandum of Agreement (MOA) from January
through June 2004. Due to missed sampling events and inability to meet detection levels
for certain metals Pace was relieved of their contractual commitments and MCFRBA
hired Meritech Laboratories to conduct the sampling and analysis as specified in the
MOA between the MCFRBA and the State of North Carolina’s Division of Water
Quality. All known QA/QC issues are denoted in the remarks section of the monthly
spreadsheets that have been submitted to NCDWQ. The following significant exceptions
occurred:
January 2004
Data was not collected at B8290000, B82302000, B8305000, B8306000, B8320000,
B8339000, B8340130, B8340650, B8348000, B8349000, B8315000, and B8340100 due
to extreme weather conditions and high water levels. Contractor was also unable to meet
35
the minimum detection levels specified in the clean metals section of the MOA for Cd,
Cr, Pb, and Zn.
February 2004
Data was not collected at B8290000, B82302000, B8305000, B8306000, B8320000,
B8339000, B8340130, B8340650, B8348000, B8349000, B8315000, and B8340100 due
to failure of contractor to properly schedule sampling events. Contractor had problems
due to weather but it was to late in the month to re-schedule the sampling event.
March 2004
Contractor was unable to meet the minimum detection levels specified in the clean metals
section of the MOA for Cd, Cr, and Zn.
May 2004
Contractor was unable to meet the minimum detection levels specified in the clean metals
section of the MOA for Cd, Cr, and Zn. Also, the contractor did not collect temperature,
ph, and dissolved oxygen at several stations. This missing info is denoted in the remarks
column on the data spreadsheet that was submitted to the state.
IV.B
ASSOCIATION SIGNIFICANT ISSUES
During calendar year 2003, the following key events occurred.
•
The MCFRBA revised its Memorandum of Agreement with the State of North
Carolina. Changes were made to the detection levels required by the MOA to better
reflect the limits of technology. Figure 43 lists the changes.

Phase II of the productivity study was finalized and Dr. Whalen presented his
findings at the August annual meeting. We are awaiting a final report.
The design and acquisition for the Little Cross Creek BMP project was initiated.
SIMILABS/Meritech collected ambient data for the period January 1, 2004 through
December 31, 2004 and this data was reported to NCDWQ. Exceptions noted above
and on the monthly data submittals.
An aerial infrared survey was conducted on Cross Creek. Follow-up site visits were
made, and follow-up sampling was scheduled for January through March 2005.
The MCFRBA worked with the Western Wake Partners to develop a proposed
nutrient management strategy for the middle Cape Fear River. The strategy was
submitted to NCDWQ in December 2004.
The protocol for chlorophyll a sample collection was changed from a surface grab
sample to a depth-integrated sample in November 2004. Additionally, the
chlorophyll a samples will now be collected on a year round basis instead of only in
the summer months as the MOA specifies as the minimum requirement.
IV.C
FIELD AUDIT
No field audit was conducted by NCDWQ, therefore there is nothing to report for
calendar year 2004.
