Improvement of technology for identifying sources and range of pollution is key in field surveys, investigation of pollutant migrations processes, and remediation processes. This project is constituted of two parts, one is the comparison of available technology for pollution identification, and the other is investigation of pollutant migration mechanisms.At first, seven cases of NAPLs pollution have been chosen to make clean how effects of geomorphology, geology and groundwater movement on the pollution processes. Secondly, available technologies for pollutant detection were compared with each other to check their feasibilities used in field. Thirdly, TCE solution and gaseous TCE behaviors in saturated-unsaturated zone have been investigated on small scale (columns) and median scale (lysimeter). Finally, NAPLs pollution, remediation measures and groundwater pollution information in Internet have reviewed.According to our researches, many NAPLs pollution cases were found in unsaturated zone. However, little research has been done to make clean the present, behaviors of pollutants there. Improvement of detection technology is not meant only to develop new method, but depends largely on our knowledge on pollutants'behaviors. It should be said that the date and knowledge obtained here can be used as the guideline for improving pollutant detection technology in future.

改进查明污染源和范围的技术是实地调查、调查污染物迁移过程和补救过程的关键。本研究分为两部分，一部分是污染识别技术的比较，另一部分是污染物迁移机制的研究，首先选取了7个非水相污染案例，分析了地貌、地质和地下水运动对污染过程的影响。其次，对现有的污染物检测技术进行了比较，以检验其在现场应用中的可行性。第三，在小尺度（柱）和中尺度（蒸渗仪）上研究了饱和-非饱和带中TCE溶液和气态TCE的行为。最后，本文综述了NAPLs污染、修复措施以及互联网上的地下水污染信息，根据我们的研究，在包气带中发现了许多NAPLs污染案例。然而，很少有研究已经做了清理的现状，污染物的行为。检测技术的进步不仅仅是开发新的检测方法，更重要的是对污染物行为的认识。可以说，本文所获得的数据和知识可以作为今后改进污染物检测技术的指导。
