Rapid increases in the swine (Sus scrofa domestica) population in the 1990s and associated potential for nitrate N pollution of surface waters led the state of North Carolina to adopt stringent waste management regulations in 1993. Our objectives were to characterize (i) nitrate N movement from waste application fields (WAFs) in shallow ground water, and (ii) soil, hydrologic, and biological factors influencing the amount of nitrate N in the adjacent stream. A ground water monitoring study was…

Mitigation of shallow groundwater nitrate in a poorly drained riparian area and adjacent cropland.
TLDR
Within 6 m of the riparian/cropping system transition, NO3 was virtually undetectable and chloride data suggested that NO3 dilution occurred from recharge by precipitation, however, a sharp decrease in NO3/Cl ratios as water moved into the riparians area indicated that additional dilution of NO3 concentrations was unlikely.
Surface water and groundwater nitrogen dynamics in a well drained riparian forest within a poorly drained agricultural landscape.
TLDR
Data suggest that the riparian forest plays a role not only in reducing export of NO3- from the cropping system to the river but also in processing nutrients from river water.
MONITORING NITRATE CONCENTRATION IN SHALLOW WELLS BELOW A VEGETABLE FIELD E
The development of best management practices (BMP) and allocation of pollution among land users in a watershed through the total maximum daily load process (TMDL) requires an understanding of the…
Detecting groundwater contamination of a river in Georgia, USA using baseflow sampling
Algal blooms and fish kills were reported on a river in coastal Georgia (USA) downstream of a poultry-processing plant, prompting officials to conclude the problems resulted from overland flow…
Nitrate, phosphate, and ammonium loads at subsurface drains: agroecosystems and nitrogen management.
TLDR
The results demonstrate that fall manuring increased nutrient losses in subsurface-drained cropland, and hence this practice should be redesigned for improvement or discouraged.
Measurements of Nitrate Leaching from a Hillslope Cropland in the Central Sichuan Basin, China
Nitrate losses through leaching were studied in a crop field in the central Sichuan Basin, southwestern China, during 2003 to 2006. Nitrate accumulations and losses via leaching were measured using…
Surface-water quality in agricultural watersheds of the North Carolina Coastal Plain associated with concentrated animal feeding operations
The effects of concentrated animal feeding operations (CAFOs) on water quality were investigated at 54 agricultural stream sites throughout the North Carolina Coastal Plain during 2012 and 2013.…
Nitrogen mass balance in fields irrigated with liquid swine waste
Over the past 15-years, swine-producing confined animal feeding operations (CAFOs) have proliferated throughout the Southeastern United States, particularly in North Carolina. Waste at these…
Nitrate contamination in groundwater on an urbanized dairy farm.
TLDR
The isotope and Cl/Br ratios indicate that nitrate contamination in these drinking wells are not from septic systems, but are the result of animal waste leached from pastures into groundwater during 35 years of dairy operations which did not violate any existing regulations.
Identifying Riparian Buffer Effects on Stream Nitrogen in Southeastern Coastal Plain Watersheds
TLDR
It is suggested that stream TNC could potentially be reduced by 34 % if buffers were adequately restored on all cropland, and model comparisons of AICc values indicated that non-headwater buffers may contribute little to stream T NC.

Tracing nitrate transport and environmental impact from intensive swine farming using delta nitrogen-15.
TLDR
This study shows that riparian buffers are not always adequate to prevent discharge of concentrated nitrate in ground water from commercial swine farms in the Mid-Atlantic Coastal Plain, and that additional measures are required to ensure non-discharge conditions.

TLDR
Riparian buffers appear effective in reducing nitrate in ground water discharging to Coastal Plain streams.
Long-term effects of nitrogen fertilizer use on ground water nitrate in two small watersheds.
TLDR
Determining ground water quality responses to new agricultural practices may take decades in some watersheds, but time-of-travel calculations and tritium data showed ground water resides in these watersheds for decades.

TLDR
By developing a better understanding of the hydrogeologic settings in which riparian buffer zones are likely to be inefficient the authors can develop improved nutrient management plans.

TLDR
Nutrient removals in the riparian forest are thought to be of ecological significance to receiving waters and indicate that coupling natural systems and managed habitats within a watershed may reduce diffuse-source pollution.
Where did all the nitrogen go? Fate of nitrogen inputs to large watersheds in the northeastern U.S.A.
To assess the fate of the large amounts of nitrogen (N) brought into the environment by human activities, we constructed N budgets for sixteen large watersheds (475 to 70,189 km2) in the northeastern…
