| 摘 要： | An integrated evaluation system under randomness and fuzziness was developed in this work to systematically assess the risk of groundwater contamination in a little town, Central China. In this system, randomness of the parameters and the fuzziness of the risk were considered simultaneously, and the exceeding standard probability of contamination and human health risk due to the contamination were integrated. The contamination risk was defined as a combination of ＂vulnerability＂ and ＂hazard＂. To calculate the value of ＂vulnerability＂, pollutant concentration was simulated by MODFLOW with random input variables and a new modified health risk assessment （MRA） model was established to analyze the level of ＂hazard＂. The limit concentration based on environmental-guideline and health risk due to manganese were systematically examined to obtain the general risk levels through a fuzzy rule base. The ＂vulnerability＂ and ＂hazard＂ were divided into five categories of ＂high＂, ＂medium-high＂, ＂medium＂, ＂low-medium＂ and ＂low＂, respectively. Then, ＂vulnerability＂ and ＂hazard＂ were firstly combined by integrated evaluation. Compared with the other two scenarios under deterministic methods, the risk obtained in the proposed system is higher. This research illustrated that ignoring of uncertainties in evaluation process might underestimate the risk level.
