The purpose of this project is to develop methods for restoring and creating wetland habitats in the Southern Appalachian mountains, and to educate landowners about the importance of mountain wetland systems. A training center will be established to demonstrate effective watershed best management practices (BMPs). Also, a comprehensive education program will be conducted throughout the Yadkin Basin for landowners, concerned citizens, natural resource managers, and public officials.
This project educates restoration professionals, state agencies, landowners, and consultants about proper restoration methods and the benefits of restoration efforts in the Coastal Plain. There is currently a need to restore stream, riparian, and wetland systems in the Coastal Plain of NC, due in part to mitigation requirements, state and federal water quality objectives, and increased societal value placed on these systems. Two demonstration projects, totaling approximately 700 feet of stream and riparian corridor, will be established on Coastal Plain streams which will become a focal point for a number of workshops and tours focusing on nonpoint source pollution, coastal restoration, and best management practices.

surface and groundwater from agriculture. The document discusses management
measures for nutrient management, pesticide management, erosion and sediment
control, facility wastewater and runoff from confined animal facilities, grazing
management, and irrigation water management. BMPs were evaluated based on their
cost-effectiveness of the practices in terms of: pollutant source reduction,
reduction of pollutant delivery to water resources, ease of farmer implementation
and operation, and proper installation and maintenance.

Thousands of acres of shellfish waters in NC and other coastal U.S. states are permanently or conditionally closed to harvesting due to elevated levels of bacteria. The source(s) of the bacteria is rarely known, and fecal coliform levels determined using traditional monitoring approaches do not differentiate relative contributions of human and animal sources.
This project will investigate sources and loads from two watersheds with active
crop and forestry agriculture, compare and contrast transport vectors and watershed
processes contributing to the problem, develop program protocols for monitoring
and management strategies within NC-DEH Shellfish Sanitation program to further
their capabilities to protect public health, and transfer this information to
the scientific community, students, state agencies, and public.

Streams in eleven watersheds have been identified as impaired based upon the
degraded status of the benthic macroinvertebrate community. This impairment
was due to a range of factors, including low dissolved oxygen, habitat degradation
or specific chemical pollutants. A key objective of the WARP, (Watershed Assessment
and Restoration Project) was to identify the major causal factors leading to
the impairment in each watershed, and to suggest solutions to identified problems.
Contract morphology assessment services were used only where DWQ staff had determined
that habitat degradation was likely a major contributor to the poor condition
of the benthic community.
Habitat degradation can manifest itself in a number of ways, including loss
of stable habitat due to sediment deposition, excessive bed and bank scour due
to watershed development, and habitat simplification due to channel modification,
among others. Solutions to habitat degradation problems range from the relatively
straightforward (e.g. stream bank stabilization activities to reduce local bank
sediment inputs on streams with fundamentally sound morphology) to complex projects
to recreate natural morphology for long, highly modified reaches. The required
services were limited to morphologic assessment activities undertaken to lay
the groundwork for future restoration. Restoration design was not part of the
scope of work for this contract, although a conceptual outline of the general
restoration approach was part of the required services.

Water quality in the White Oak River Basin is highly variable. Portions of the White Oak River, Core Sound and Back Sound are rated as excellent, supporting areas classified as outstanding resource waters (ORW) and high quality water (HQW). Also, the water quality in the Newport and North Rivers is generally high. However, water quality in the New River has suffered as a consequence of agricultural activities, population growth and development. These conditions have caused an increase in flooding, stream bank erosion, incidents of shellfish closures, and sedimentation. In addition, portions of the New are classified as nutrient sensitive. All rivers in the basin have periods of anoxia, as well as incidents of high fecal coliform counts and turbidity levels, according to the White Oak Basinwide Assessment Report. Water quality monitoring to evaluate the effectiveness of wetland construction and stream bank restoration BMPs includes weekly and bi-weekly grab samples data taken upstream and downstream of five targeted sub-basin will continue to be monitored monthly. Single-event composite storm samples will be collected using automatic samplers and/or a field technician at upstream/downstream sites for five storms per year. The pre- and post-BMP monitoring periods were approximately one year. Samples were analyzed for nutrients, sediment and fecal coliform bacteria.

Previous studies of North Carolina private water supply wells indicate that
up to 10% may contain nitrate-nitrogen at levels exceeding the safe drinking
water standard of 10 mg/L. A recent water testing program conducted by the NC
Division of Environmental Health found that about 10% of wells located near
swine farms were contaminated. Many private wells in eastern North Carolina
are particularly susceptible to contamination because they are shallow (typically
less than 50 feet deep) and poorly constructed. In addition, private well users
are not aware of the health risks associated with drinking contaminated water
or how to protect their wells from contamination sources including animal and
human waste and fertilizers.
This project screened a minimum of 1,000 private water supply wells for nitrate
contamination over a two-year period in the three river basins. Some of the
participating wells were found to exceed the safe nitrate-nitrogen level of
10 mg/L. Each of the well users will receive follow-up water testing and education
through the NC Farm*A*Syst/Home*A*Syst program.

Wellhead protection is a voluntary, preventive program designed to protect public water supply wells. The goal of wellhead protection is to prevent contaminants from entering public water supply wells. The Wellhead Protection Plan is a program that assists communities in accomplishing this goal by managing the risks on the land that contributes water to the wells.
The EPA has provided guidelines and technical documents defining this program.
This is a guidance document specific to North Carolina. The target audience
of this document is local elected officials, as well as town and county employees
such as managers, clerks, and operators of public water supplies. This guidance
document increases the amount of progress the communities make independently,
and decreases the PWS and RWA time commitment required. Making the planning
process simpler to understand and more accessible will encourage more communities
to develop Wellhead Protection Plans, thus providing better protection for out
state's groundwater.

Some 56,000 acres of North Carolina's estuarine waters are permanently closed
to shellfish harvesting as a result of bacterial contamination. Jumping Run
Creek, a tributary of Bogue Sound in the White Oak River Basin, is a "conditionally
approved closed" tidal creek and shellfish harvesting is only permitted
during very dry periods, amounting to only a few open days per year. Water quality
monitoring by the N.C. Cooperative Extension Service as part of an on-going
EPA 319 project has identified high bacteria concentrations in runoff from ditches
that drain the surrounding forests, roadways, residential community and industrial
complex.
This project increased the knowledge of coastal shellfish watersheds and potential
of stormwater BMPs for improving shellfish quality. Changes in land use and
land cover in the Jumping Run Creek watershed were analyzed using aerial photography
data from the 1960's to 1990's. Using GIS, the degree and location of ditching,
paving, and vegetative cover were quantified. These data were regressed against
30 years of Shellfish Sanitation bacterial data collected in Bogue sound. This
study indicated that the extent of ditching significantly correlated and was
the best indicator of bacterial loading. In addition, comparison of storm flow
versus non-storm flow water quality data has revealed that the majority of the
bacteria loading occurs during storm flow. Monitoring of a constructed wetland
at the Carteret Craven Electric Cooperative BMP site indicated the two-phased
stormwater wetland constructed in 1999 and 2000 has significantly reduced the
volume of freshwater entering Jumping Run, thus reducing the potential survival
of bacteria in the mouth of the creek.

Portions of Sandy Creek are classified as NPS impaired by the Tar-Pamlico River Basinwide Management Plan. Current programs to implement agricultural BMPs through the North Carolina Agricultural Cost Share Program are focused on traditional practices to filter runoff as it leaves fields. To prevent runoff pollution at the source, the Cooperative Extension Service and Soil and Water Conservation Districts are promoting the adoption of conservation tillage in crops that are highly erosive and do not have no-till technology developed for field application. No-till tobacco and cucumber technology has been developed in the Devils Cradle Watershed Project in Franklin County in 1996 and 1997 and has been shown to be cost effective. This technology is still considered as a high-risk experimental practice by producers because of potential yield reductions and adverse social pressure. Transfer of this technology to other watersheds is facilitated by this project.

The engineering design problem has evolved from one of water conveyance to designing a channel that is self-maintaining, aesthetically pleasing, and provides optimum biological diversity. Historically, natural channel processes have been addressed by fluvial geomorphologists and to lesser degree biologists. More recently, stream classification and bioengineering have been used to describe stream types, condition, and to develop strategies for stream improvements. While interest in natural channel design is high, the science and technical database for accomplishing successful restoration is limited. Increasingly, land development organizations are being required to mitigate impacts to streams by utilizing natural channel design technologies. A synthesis of scientific information related to stream restoration along with a process for implementation and evaluation is greatly needed by land development organizations and resource review agencies.
Purpose of Grant:
1) Conduct a thorough research and review of scientific literature related to
stream restoration practices,
2) Develop a recommended process for stream restoration by integrating current
knowledge and practices,
3) Develop measures of effectiveness for use in evaluating successful stream
restoration and mitigation,
4) Conduct a workshop for NCDOT and resource review agency staff to present
results of the project.

The drainage areas within the North Carolina Upper Cape Fear River basin are designated as high priority watersheds by the State. Urbanization and agriculture have contributed to impaired water quality in the basin. Urban nonpoint pollutants include sediment from construction activities, impervious surface runoff, and runoff of over-applied fertilizers and pesticides from lawns. A key agricultural concern is livestock access to streams. Through training and demonstration programs on stormwater management and stream restoration, this project involved local governments and agents on innovative site planning, design and policy tools to protect water resources over the long term, while facilitating responsible growth management in the watershed. Training for youth educators of underprivileged students was also included.
The objectives are to: 1) to develop an interactive internet educational program focusing on our research with water reclamation and reuse utilizing multimedia developed in cooperation with local secondary schools, N. C. Cooperative Extension Service, Chatham 4H, and local businesses; 2) to engage public school students of Chatham and Randolph Counties in the development and utilization of web page interactive tools to conduct, monitor and discuss experiments within our local water reclamation and research projects; 3) to provide technical assistance to public school teachers to develop content materials which focus on our water reclamation and reuse research and related water quality issues. We will a) create computer software that will convey complex environmental engineering relationships within a user friendly format accessible by a wide range of academic abilities, b) prototype an environmental monitoring network connecting the research system to the classrooms to convey real time data from water reuse system sensors for compilation and evaluation by the public school students, c) increase the understanding by students and teachers of the water quality issues that face North Carolina, d) provide the basis to engage public school teachers and students with university personnel on a larger scale, and e) assist NCSU faculty with enhancing their teaching skills and organizing complex information and effectively communicating it to individuals generally unfamiliar with the subject matter.
This project reduces fecal coliform levels in Bear Creek sufficiently to enable opening of its SA waters to shellfishing with greater frequency and maintains acceptable levels on a long-term basis. Residential, agricultural, roadway, and forestry best management practices were installed and evaluated for their ability to reduce coliform, sediment, and nutrient loads. Indicators of success were increased numbers of shellfish acres conditionally open and higher amount of rainfall required for closure of conditionally open shellfish areas.
Though numerous studies have evaluated the impacts of boat pump out waste, recommendations for a treatment system design are conservative, based on a lack of detailed information and a limited management strategy. These conditions present an economic disincentive for compliance. Volume, chemical and biological characteristics of boat pump out waste will be monitored monthly at 3 marinas in coastal North Carolina for 1 year. The measure of BOD is considered one of the critical parameters for assessing potential water quality impacts and treatment system design. The measure is a general one, and may not be a good indicator of the potential water quality impacts of boat pump out waste, especially when managed differently. Wastewater reuse strategies will be developed based on characterization data and water quality parameters or combinations of parameters will be suggested to better assess potential water quality impacts.
The Watauga River Watershed (HU-06010103) is located in Watauga and Avery Counties. The watershed drains 184 mi2 of forested, agricultural, urban, residential, and resort land uses, including 9 golf courses and 3 ski resorts. The Elk River and Shawneehaw sub-watersheds is targeted for water quality monitoring, BMP implementation and demonstration. Streambanks in both watersheds are eroding as a result of cattle access to the stream, increases in impervious cover and subsequent increases in peak runoff. All pollution sources in these sub-watersheds is inventoried in order to develop a comprehensive system of BMPs and educational programs.
This purpose of this project is to prevent water quality degradation in the Watauga River Basin through a combination of land acquisition, implementation of best management practices, educational programs and workshops, and coordination with other public programs. Degraded streams were returned to their natural function of supporting aquatic habitat, including trout; wetland function and habitat were restored; stormwater controls and management were improved through educational workshops and pollution prevention; and future stream degradation was prevented through riparian land acquisition, preservation, and education.
An effective nutrient management system for domestic sewage should reduce and reuse sewage. The research emphasis is on treatment and reuse rather than disposal. The continual disposal of sewage with minimal treatment into natural soils and its parent materials has increasing potentials for contributions to surface and groundwater contamination. Low cost, low maintenance and effective sewage treatment and management prior to use within the landscape lessens the potentials for adverse impacts on public and environmental health. The wastewater treatment system for Neon Impressions proposed to be installed as a part of the renovation of Triangle School, Chatham County, is designed to utilize the combination of a septic tank, two constructed wetland cells in series, UV and chlorination for disinfection, soil filters and the reuse of treated water to flush toilets. The general objectives of this project are to demonstrate and conduct preliminary evaluations of the feasibility of treating and recycling 1200 gal/day of domestic wastewater for flushing toilets. The results will be evaluated as a part of our continuing research program with wastewater treatment systems, presented at conferences and workshops and published in scholarly journals.
The Upper French Broad Basin (HU 06010105 and DWQ 04-03-01) is located in Transylvania County. Streams in this river basin are classified as High Quality Waters, Outstanding Resource Waters (ORW), and Trout Waters (TR). Water quality monitoring conducted by the NC Division of Water Quality has documented water quality impairments resulting from agriculture and development along case sensitive trout streams. The proposed CWMTF project will support riparian restoration to reduce impacts of sedimentation and improve trout habitat and water based recreation. Funding requested from CWMTF is $300,000. This funding will be used to repair degraded stream channels and streambanks, restore riparian wetlands, establish riparian forested buffers, and conduct educational programs to prevent future degradation from land use changes.
In a time of increasing public awareness of environmental concerns and dynamic policy and regulation related to the agricultural sector, it is important that agricultural producers be appraised of environmental requirements affecting them and the ways in which they can both meet those requirements and continue production as economically as possible. The goal of this project is to 1) assist the farming community in identifying environmental requirements potentially affecting them, 2) help assess potential problems this community experiences or may experience with regard to compliance, and 3) assist this community in complying with environmental requirements in a prudent and cost-effective manner. The farming community includes both agricultural producers and local agency personnel who are the information providers to producers. To achieve these goals, a team of experts from a number of organizations has been assembled.
The project has been divided into eight tasks, which focus on development of
material and training programs, identification of experts, cataloging of material,
quality control, assessment, and project continuation.
