Groundwater is an important part of water resources, but also the sustainable development of China is an important limiting factors. According to statistics, about 70% of the population in the groundwater as the main source of drinking water. In the northern region, groundwater development and utilization rate is higher, the percentage is even more than 90%, groundwater has become the people's living and production main source of water, the quality of people's life and production is closely related with the groundwater conditions. Hutuo alluvial fan is located in the North China Plain in two, including Shijiazhuang City and subordinate counties, an area of about 6000km ~ 2. Groundwater is the main source of water supply in this area, with the increase in human activity brought a variety of harmful substances in the groundwater pollution increases every year, declining groundwater quality, seriously endangering the safety of drinking water. Since the late 1970s, Groundwater Contamination began to attract attention. However, preliminary assessment of groundwater quality domestic use more conventional inorganic indicators characterize groundwater quality can not be the real situation, so far, the region has not been carried out for the safety of water supply system of investigation and evaluation of groundwater pollution, groundwater contamination (especially organic pollution) overall condition lack of understanding. The study, \Field investigations and hydrogeological field survey sampling groundwater contamination test results, the regional water quality analysis, and use a variety of methods for groundwater quality assessment comparative evaluation to find a suitable method for evaluating this study, a comprehensive evaluation of water quality in the region, as residents of the region's water security to provide technical assurance. Research shows: single factor index method results represent the lower boundary of groundwater quality status; comprehensive index evaluation results lighter, which Nemerow index improved after application of pollution typical to the region; Grey Clustering Evaluation Method evaluation results distorted by adjusting the weights obtained after the evaluation results can provide a reference for the regional groundwater quality; fuzzy comprehensive evaluation method is more suitable evaluation index system, and the multiplication operator evaluation results add significantly classification, information utilization and accuracy are relatively high, is more appropriate in this area can be utilized. The evaluation found that local water quality is good in most areas, ultra-Class Ⅲ water points are mainly distributed in Shijiazhuang City, the new music, OK Don, Xinji and Fukasawa and other places, and mainly in urban areas, cities and towns around the area, sewage both sides of the river, surface water pollution and the introduction of sewage distribution irrigation regions. Visible, groundwater pollution is caused by human activity is the direct cause. In this paper, comparison of different evaluation methods to explore summed up the advantages and disadvantages of each method, and Nemerow index method and gray clustering method to be improved for future evaluation work provides a reference for the other by comparing the existing \
