Abstract: With the development of economy and the continuous expansion of cities, the environmental risks of many water sources are increasing day by day. Nowadays, there are many studies on the environmental risk evaluation of centralized surface water area or lake-reservoir drinking water source area, but few on centralized groundwater source area. Comprehensively considering the potential risk source, the vulnerability of groundwater source, the environmental risk prevention and controling and emergency response capability of water source, the environmental risk evaluation index system and evaluation method for centralized groundwater drinking water source area were established. It was applied in 7 groundwater sources in Shenbei New District, Shenyang city. The conclusions were as follows: the potential sources of risk and vulnerability were external and internal factors respectively, which were the main factors affecting the environmental risk of groundwater sources. The CLJPSC Water Source (2793), YJ Water Source (2322) and HJ Water Source (2082) were the medium-risk water sources, and the remaining NCGSB water source (1969), HJJSC water source (1790), SMJT water source (1551) and GGSYGLC Water Source (1464) were at low environmental risk.
