General Operational Chemical 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支撑水体状态有效管理所需的完备信息。作为决策者的基础性工具，该类计划可用于评估已实施措施的成效，以及各项既定目标的达标合规程度。 化学监测网的设立宗旨为：补充并验证针对MSBTs及MSBT组的IMPRESS分析（尤其聚焦于化学状态维度），同时提供相关数据以评估自然条件引发的指标长期趋势变化，以及人为活动污染物所造成的影响。 为应对《欧洲议会与理事会2000年10月23日第2000/60/EC号指令》（该指令为欧盟水政策领域的共同体行动搭建了制度框架）实施过程中涌现的新挑战，启动全新监测计划以获取地下水体化学状态分类判定所需信息已成为必要之举。上述义务已在该指令的第8条及附件V中予以明确规定。
