abstract = "This contribution describes the methodology for monitoring the effectiveness of the EU Nitrates Directive Action Programmes in Denmark (EC, 1991 and EC, 1999). The legal requirements for this type of monitoring are set down in the Nitrates Directive, Article 5(6). Denmark is an intensive farming country (60% of the country area) and during the last 15 years the pig and poultry production has increased considerably. Thus agriculture is the main source of nitrate pollution in groundwater and surface water. More than 40% of the shallow groundwater (0-30 m) is heavily polluted with nitrate and periods of oxygen depletion in the inner Danish seas are common. Natural and human factors influence the nitrate concentrations and action programmes for reducing nitrate pollution in the aquatic environment are presented. Finally, the effect of monitoring programmes for groundwater and surface water is described and some results are presented.",
