Groundwater environmental assessment is a useful tool for environmental planning and decision-making. In this paper, an index system, with multi-level structure, was first established for groundwater environmental risk assessment, by using twenty-two qualitative and quantitative indicators. Meanwhile, the groundwater environmental risk was defined as a multiplication between grade of risk and importance of risk, and the classification standards for grade of risk and importance of risk were also primarily established, individually. On the bases, a fuzzy multi-attribute decision-making model was proposed for the assessment of groundwater environmental risk.
