Abstract Based on the analysis of hazardous waste landfill (HWL)'s characteristics of construction,operation and environmental accidents,this paper identifies its maximum credible accident as the damage of linear system,and determines the safety protection objective as preventing people around the site free from the harm due to drinking groundwater contaminated by leachate leakage.Furthermore,it proposes a probabilistic-risk based method,as well as principles and procedures underlying,to determining the Safety protection distance (SPD).This method was then applied to calculate the SPD for a HWL in the central China.The result indicates that:with the consideration of different contaminants,the SPD varies from the maximum value of 620m for the protection purpose of Cr's carcinogenic effect,and the medium value of 448m and 355m for the protection purpose of Cr and inorganic fluoride's non-carcinogenic effect,to the minimum value of zero for the protection of Zn'hazardous effect.In addition,being influenced by the uncertainties of precipitation,depth of vandose and aquifer,and saturated permeability of vandose and aquifer,there is great uncertainties in the value of SPD.The corrective SPD is 990m and greater than the value of 800m regulated in the standard of GB 18598-2001.This paper finally pointed out that a specific value for each HWL with the consideration of variance in precipitation,hydrogeological condition,types and toxicities of received waste,and characteristics of linear system,rather than a uniform value for all HWL should be recommend in determining the SPD.
