Managing ground water contamination from agricultural nitrates
Ground water contamination from agricultural nitrates poses potential adverse health effects to a large segment of the rural population of the United States. Contamination is especially prevalent in livestock intensive areas, which produce large quantities of animal waste with substantial nitrogen …

Relationships Between Hybrid Poplar Tree Extractives and Ground Water Contamination at a Phytoremediation Site
… hydrocarbons (PAH) had entered the site soil and ground water. After planting, a seasonal ground water testing program began that monitored the progress of remediation by measuring the concentration of the 10 predominant PAHs in the contaminant plume: naphthalene, acenaphthylene, acenaphthene, …

Evaluation of a nontidal riparian wetland as a naturally occurring decontamination zone
… that limit the chemicals impact on surface and ground water contamination. The agricultural practices of the Atlantic Coastal Plain in Virginia have resulted in many bottom land areas of forests and wetlands being left uncultivated, while the upland areas are being utilized for intensive …

Nitrogen utilization in tall fescue (Festuca arundinacea Schreb.) pastures fertilized with nitrogen or grown with alfalfa (Medicago sativa L.) or red clover (Trifolium pratense L.)
… red clover. Total kg N accumulated ha⁻¹ in above-ground herbage was higher (P≤ .05) for the grass-legume mixtures than N-fertilized tall fescue. Esophageally fistulated steers grazing stockpiled tall fescue-alfalfa selected forage higher (P ≤ .05) in N concentration than steers grazing the other …

Extraction of alcohols from gasoline using solid phase microextraction (SPME)
… agency (EPA) because of the possibility of ground water contamination. The current trend is to use EtOH, therefore this work focuses on the analysis and quantification of EtOH in gasoline by solid phase microextraction (SPME). The major problem in quantifying EtOH in gasoline is the …

Induced Phytoextraction of Lead from Contaminated Soils by Panicum virgatum, Enhanced with EDTA, Citric Acid, Benomyl, Propiconazole and Nitric Oxide
<p>Soil lead (Pb) contamination represents a major environmental and public health risk. Conventional Pb remediation methods are typically expensive and risk further environmental damage. Phytoextraction has emerged as an alternative heavy metal remediation method with the potential for reducing …
