The impact of swine lagoon seepage on shallow groundwater quality: Groundwater remediation through lagoon closure and pumping
Anaerobic lagoons have been used extensively since about 1960 to temporarily store and partially treat livestock waste from concentrated animal production facilities. An earlier study characterized...

Tile water quality following liquid swine manure application into standing corn
The quality of water draining fields fertilized with liquid swine (Sus scrofa) manure (LSM) sidedressed into standing corn (Zea mays L.) at rates ranging from 0 to 94 m(3) ha(-1), either topdressed...

Detection and occurrence of antimicrobially resistant E-coli in groundwater on or near swine farms in eastern North Carolina
The use of antibiotics for growth promotion and disease treatment by the commercial swine industry has led to high proportions of multiple antibiotic-resistant enteric bacteria being shed by these...

Movement of lagoon-liquor constituents below four animal-waste lagoons
Movement of liquor constituents from animal-waste lagoons has the potential to degrade ground water quality. The depth of movement and concentrations of lagoon-liquor constituents in the soil...

Seepage evaluation of older swine lagoons in North Carolina
Thirty-four swine waste lagoon systems in North Carolina were examined for evidence of seepage losses to the shallow groundwater. All were constructed prior to the state's January 1993 adoption of...

Simulating Swine Manure Transport in Soils Using the Mobile-Immobile Contaminant Transport Model
Modeling swine manure transport is an important initial step not only in understanding the behavior of this potential contaminant in the subsurface environment but also in providing a basis for...

Occurrence and diversity of tetracycline resistance genes in lagoons and groundwater underlying two swine production facilities
In this study, we used PCR typing methods to assess the presence of tetracycline resistance determinants conferring ribosomal protection in waste lagoons and in groundwater underlying two swine...

Nitrate leaching as affected by liquid swine manure and cover cropping in sandy soil of southwestern Ontario
To assess the risk that liquid swine manure (LSM) application posed to groundwater quality and determine how to manage excess nitrates, LSM pre-plant injected at 75% (LSMlow) and > 100% (LSMhigh) of...

N-source effects on temporal distribution of NO3-N leaching losses to subsurface drainage water
Understanding the temporal distribution of NO3-N leaching losses from subsurface drained ?tile? fields as a function of climate and management practices can help develop strategies for its...

Shallow subsurface drains to reduce nitrate losses from drained agricultural lands
Nitrate losses from subsurface drainage systems remain an important environmental concern. Data were collected from two drainage systems near Plymouth, North Carolina, to evaluate the effect of...
