Nitrates and Their Control in the EEC Aquatic Environmentwo major consequences: (1) an increased risk of degradation of drinking water; and (2) eutrophication of continental and coastal aquifers, which can harm fishing and tourism. EEC Member States have individually and collectively taken action to prevent further increases in nitrate levels in water and

Risk Analysis for Water Supply from a River Polluted by Nitrate Runoffe from fertilized fields. Both the runoff of nitrate and the river discharge are random variables whose combination yields the desired probability. The problem is formulated in terms of reliability theory, and the model is formally extended to cover both input variable uncertainty and risk assessmen

Nitrate Ground-Water Modeling for Agricultural and Other Nonpoint Sourcesnalytic models, and numerical transport models. Ongoing studies in Nebraska are used to illustrate several modeling approaches. Although there are a range of models that could be useful in modeling nitrate pollution in Nebraska, the data base limits the choices to relatively simple models in most ca

Principles of Monitoring and Analysisd by the standard deviation of the distribution of the predicted nitrate exposure. In the case of basin-wide nitrate monitoring, the spatial pattern of the nitrate concentration and the estimation variance are obtained by geostatistical analysis. In the second case, which refers to the impact assess

Nitrate Balances in Aquifers disposal of liquid and solid manure in rural areas, but nitrate levels are also increasing in ground water in urban areas. Input, output and storage of nitrate are investigated for some aquifers in west Germany. It is concluded that more nitrate will intrude in pumping wells and surface water cours

Integrated Water and Nitrogen Management but effective management is difficult because of the complex interactions between soil, water, and nitrogen (N). It is widely recognized that N and water management must be addressed simultaneously to develop production systems that reduce nitrate leaching. Difficulties with N and water management
