Abstract:

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.

Key words: groundwater contamination, risk management, in situ remediation, ex situ remediation, natural attenuation, remediation technology screening
