This paper used the contaminant fate and transport multimedia model (EPACMTP model) to assess the risk classification method for a national soil quality survey program. Regional sensitivity analysis, global sensitivity analysis and empirical verification were conducted. The work focused on the completeness of indicators, credibility of classification and robustness of weighting and scoring. The result showed that almost all (13in total) sensitive parameters were covered by the risk classification method, except for leachate concentration. Parameters with high sensitivity and importance were usually given relatively high weights. The scores for site area and distance to receptor were shown to be reasonable. The classification for low-risk sites were generally accurate. This study recommended that more attention should be paid to contaminant transport process. Suggestions were given on indicator weighting and scoring. We also suggested focusing on medium-and high-risk sites, as well as arsenic contaminated sites.
