Biochemistry of a Plume of Nitrate-Contaminated Ground Waterlume was delineated using three surface geophysical techniques, and sampled on vertical profiles along two transects. The plume was found to consist of an anoxic core surrounded by a halo of nitrate. The groundwater chemistry indicates that nitrification is limited by oxygen diffusion into the anoxi

Nitrate Contamination of Ground Water in Southern Ontario and the Evidence for Denitrificationtudies suggest that nitrate contamination is ubiquitous in surficial aquifers in areas of intensive agricultural activity, with concentrations commonly exceeding the drinking water limit of 10 mg/L NO.-N. There is little doubt that agricultural fertilizer is a major contributor to the elevated nitra

Nitrogen Management Research in the President’s Water Quality Initiativethe public and private sectors are required to develop safer pest controls and to adopt environmentally sensitive farm production practices. The President’s Water Quality Initiative is based on three policy objectives (Bush, 1989): First, the federal government is committed to protecting ground-wate
