The groundwater vulnerability is a basic issue for the groundwater to be protected and used reasonably, so it is one of the hot topics in the hydrogeology field. The DRASTIC method and the GOD method are used to assess the groundwater vulnerability of the second Songhua River basin, and then the assessment is evaluated by using the measured values of Cr. The results show that the DRASTIC method is better, and it could reflect realistically the vulnerability of the researched area. The groundwater environment near a river is vulnerable and easy to be polluted. In order to take advantage of the groundwater resources effectively, the well of the water source should be constructed far away from the high-risk areas.
