Groundwater pollution control and remediation technologies have been studied abroad, some technologies have been used successfully in field practice. The remediation study of contaminated groundwater in China is highly concerned recently, the national wide groundwater pollution survey has been conducted and the pollution prevention planning is ongoing, and the groundwater remediation comes into the demonstration studying stage. For a contaminated groundwater site, different kind of risk management methods can be used, and many remediation technologies can be chosen. It is very important to develop risk management strategies, and to screen the right remediation technology or the combination of technologies for a specific contaminated site. The authors deal with the risk management and the screening of remediation technologies. The major groundwater remediation methods have been discussed and analyzed through the analysis of existed groundwater pollution risk management strategies, and with the consideration of author's experiences in groundwater contaminated site study. Finally the screening procedure and methods of groundwater pollution remediation technologies have been proposed for the contaminated sites.%国际上对于地下水污染场地的控制与修复研究已经取得了许多成果,已有成功的修复实例.我国虽然起步晚,但非常重视地下水污染的防治,开展了全国范围的地下水污染调查,并进行了地下水污染的防治规划.地下水污染的控制与修复已经逐渐进入示范性研究阶段.面对地下水污染场地风险管理的不同方法,以及众多的污染修复技术,如何制定风险管理策略,如何在各种各样的修复技术中筛选合适的技术或技术组合,对于地下水污染场地的防治具有非常重要的意义.笔者分析了发达国家地下水污染风险管理策略,结合在地下水污染场地研究方面的经验,对一些主要的地下水污染修复技术进行了分析论述,提出了考虑污染物特征、场地水文地质条件的地下水污染修复技术的筛选过程和方法.
