Nitrate-Affected Water Control Network

The main objective of groundwater monitoring programmes is to generate the information necessary for effective management of the status of water bodies. They are a basic tool for decision-makers as they make it possible to assess the effectiveness of the measures taken and the degree of compliance with the objectives set. The Chemical Monitoring Network aims to complement and validate the IMPRESS analysis especially with regard to chemical status, of MSBTs, or MSBT group; and provide information to assess changes in long-term trends of indicators due to natural conditions and pollutants due to anthropogenic activity. The implementation of new monitoring programmes to obtain information to classify the chemical status of groundwater bodies has been necessary in order to meet the new challenges arising from the implementation of Directive 2000/60/EC of the European Parliament and of the Council of 23 October 2000 establishing a framework for Community action in the field of water policy. That obligation is set out in Article 8 of and Annex V to that directive.地下水监测计划的核心目标是生成有效管理水体状态所需的必要信息。此类计划是决策者的基础工具，可用于评估已采取管控措施的有效性，以及达成既定目标的合规程度。 化学监测网旨在对IMPRESS分析进行补充与验证，尤其针对MSBTs或MSBT组的化学状态；同时可提供相关信息，以评估自然条件及人为活动污染物引发的指标长期趋势变化。 为应对欧洲议会与欧盟理事会2000年10月23日发布的《建立水政策领域共同体行动框架指令（2000/60/EC）》实施所带来的新挑战，需启动全新监测计划以获取相关信息，进而对地下水体的化学状态进行分类。此项义务已在该指令的第8条及附件V中明确载明。
