The impact of swine lagoon seepage on shallow groundwater quality: Groundwater remediation through lagoon closure and pumping
January 1, 2008By Jon M. Hathaway
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...

Detection and occurrence of antimicrobially resistant E-coli in groundwater on or near swine farms in eastern North Carolina
January 1, 2005By Anderson
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
January 1, 2005By Gary M. Pierzynski
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
January 1, 2004By Ronald L. Huffman
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...

Impacts of swine manure pits on groundwater quality
January 1, 1999By I. G. Krapac
Manure deep-pits are commonly used to store manure at confined animal feeding operations. However, previous to this study little information had been collected on the impacts of deep-pits on...
