A common challenge in many cities in Europe is endangerment of natural resources due to soil and water pollution. Despite extensive investigation and remediation measures over decades and current practices of environmental management, residues of pollutants persist in soil and groundwater, reducing the functionality of many urban areas. In complex hydrogeological systems, where contaminated plumes are overlapping and/or diffuse contamination is present, technical and administrative activities have to be thoroughly planned and executed in the long term to secure the recovery of groundwater quality. Communities need a management strategy (MS) to manage soil and groundwater contamination in urban areas, especially where contamination exceeds local scales but does not reach the national level. A MS drives administrations to understand hydrogeological system properties, define new, reachable target values and give practical guidance for the implementation of necessary measures. Implementation of a MS fosters the early involvement of key stakeholders and their contribution to the development of MS itself. The strategy has proven to be an appropriate and flexible tool for the transfer of scientific knowledge to the planning, coordination and implementation necessary for the remediation of large-scale groundwater contamination.

制定七个区域含水层的地下水污染物修复策略

欧洲许多城市面临的一个共同挑战是土壤和水污染导致自然资源受到威胁。尽管几十年来进行了广泛的调查和补救措施以及当前的环境管理实践，污染物残留仍然存在于土壤和地下水中，削弱了许多城市地区的功能。在复杂的水文地质系统中，污染羽流重叠和/或存在扩散污染，必须长期彻底规划和执行技术和管理活动，以确保地下水质量的恢复。社区需要一项管理策略（MS）来管理城市地区的土壤和地下水污染，特别是在污染超过当地规模但未达到国家水平的地区。MS 促使主管部门了解水文地质系统特性，定义新的、可达到的目标值，并为实施必要措施提供实际指导。MS 的实施促进了关键利益相关者的早期参与以及他们对 MS 本身发展的贡献。该战略已被证明是一个适当且灵活的工具，可将科学知识转移到大规模地下水污染修复所需的规划、协调和实施中。
