Abstract： Currently， the progress of study goes well，the target is basic reasonable， the job of research is carried out smoothly according to the plan， parts of study have already developed in advance. Two typical demonstrate place were chosen， one is MSW landfill which is located in Shunyi County in Beijing， the other one is breeding base in Haiyan County in Zhejiang province. At the two research bases， information collecting， hydrogeological investigation， monitoring wells building， water quality monitoring， slug and infiltration testing， all of these already have been finished， and hydrogeological parameter have been achieved. These results can be used in the design of engineering demonstration. On the basis of a great deal of laboratory data， theoretical basis are built about the remediation technology of the pollution of nitrate in groundwater， which was based of the research background of engineering demonstration field. Three kinds of remediation materials developed， including activated carbon material， slow-releasing material of oxidation and biochemical integrated material. Two innovative scientific remediation technology are studied. One is unfilled PRB in situ remediation technology of groundwater pollution， which is proposed basing deeper groundwater pollution in in the north. The remediation technology has advantages of low investment， simple process flow and low cost. The multi semi-in situ remediation of groundwater system is a new groundwater remediation technology which is researched and developed through our research. The system integrated the Wetland treatment technology， Permeable reactive barriers technology and groundwater well irrigation technology as a whole. The advantages of this system are lower cost of construction and operation， easy construction， small disturbance to the groundwater environment， strong flexibility and adaptability. In terms of achievements， there have been five applied patents， two received patents. six papers， which including three SCI， and two innovative technologies in the research group.
