NUTRIENT IMPACT OF SWINE CAFO WASTE ON SURFACE WATER AND GROUNDWATER IN EASTERN NORTH CAROLINA
… in concentrated animal feeding operations (CAFOs). Swine wastewater typically contains elevated nutrient concentrations and is stored in lagoons (LG) until land application occurs. Periodically, nutrient-rich wastewater is applied to spray fields (SFs) to facilitate plant uptake by crops; …

New applications of STEPL watershed modeling of CAFO feedlot runoff and implications of surface water impacts
Concentrated Animal Feeding Operation (CAFO) cattle feedlot runoff is hydrologically modeled using the Spreadsheet Tool for Estimating Pollutants Load (STEPL). STEPL estimates the annual nutrient load of nitrogen and phosphorus, among other pollutants, by land use for a watershed. The Dry Creek …

Occurrence, Fate and Transport of the Primary Metabolites of Trenbolone Acetate in CAFO Soils and Surface Water Runoff
… in confined animal feeding operation (CAFO) surface soils following implantation. To quantify steroid concentrations, a gas chromatography/tandem mass spectrometry (GC/MS/MS) analytical method was developed and applied to the analysis of solid and aqueous samples. 17α- trenbolone, …

Phosphorus Losses From Simulated Dairy Land Uses of Management Intensive Grazing and Concentrated Animal Feeding Operations
… to concentrated animal feeding operations (CAFOs). However, questions remain regarding the amount of phosphorus (P) loss from pasture-based dairies. Therefore, the goal of this study was to quantify P losses via runoff from grazing dairy systems and CAFO hay production. Four land use …

Planning Gone Hog Wild: Mega-Hog Farm in a Mountain West County
… hog concentrated animal feeding operation, or CAFO. While a number of studies have explored the socio-economic and environmental aspects of hog farms, few studies have focused on the planning process and evaluated its effectiveness in dealing with the threats and challenges that a CAFO poses. …

Stable Isotope and Geochemical Characterization of Nutrient Sources in the Big Creek Watershed of Northwest Arkansas
… of a concentrated animal-feeding operation (CAFO) in Newton County, Arkansas near Big Creek, a tributary of the Buffalo National River, has raised concern over potential degradation of water-quality in the watershed. In this study, isotopic tools were combined with standard geochemical …

Private land, public interest : small town meets big dairy
… of a Concentrated Animal Feeding Operation (CAFO) in their county. In particular, it is an attempt to understand and document the process by which a sparsely-populated rural community organizes itself in an attempt to disallow this type of facility from being sited in their area. Like poor …

Emissions From Concentrated Animal Feeding Operations During Wet and Dry Periods in the Southeastern United States
… several concentrated animal feeding operations (CAFOs) that emit a variety of gases, including sulfur dioxide (SO<sub>2</sub>). The hypothesis was that the concentration and spread of SO<sub>2</sub> emissions from these sources would differ between wet and dry periods over the CAFO locations. In …

Cattle manure characteristics in relation to manure accumulation period and seasonal impacts in the intermountain west
… at one concentrated animal feeding operation (CAFO) from different months with different seasonal effects. For each sample collection, different manure accumulation periods were selected ranging from 7 to 90-day old manure. For each accumulation period, three cattle pens were selected based on …

Determination of particulate emissions from confined animal housing
Determining particulate emission from mechanically ventilated confined animal feeding buildings is a challenging undertaking. This is due to the relatively large particle sizes involved, wide size range and difficulties in measurement of the ventilation rate of the building. This study seeks to …

Concentrated Animal Feeding Operations: Hazards, Environmental and Health Risks as the Latent Products of Late Modernity
<p>CAFOs raise tens of thousands of animals in confined cages and feedlots, feed them high calorie diets, and ship them to slaughter in record time. These factory farms (as they are sometimes called) devastate neighboring environments with the releases of toxic methane gas and animal waste. …
