Abstract: The cancer risk assessment model recommended US EPA was used to access the carcinogenicity of disinfection byproducts (DBPs) in water distribution network in a Southern City of Jiangsu. The trihalomethanes (THMs) and haloacetic acids (HAAs) with carcinogenic risk was considered to be the research focus on the cancer risk assessment. The carcinogenic risk along the pipeline was explored through monitoring the changes of the THMs and HAAs .The results showed as follows: the disinfection by-products increased along the pipe network and cancer risk increased too. The maximum cancer risk within the area of water supply pipe network was calculated. The R_Tmax was 4.72×10^-5, which was between5.10^-5 and 10^-6. So the carcinogenic risk could be accepted and some measures could be considered to be taken to reduce the carcinogenic risk.

Abstract: According to the fuzziness of water quality in water distribution system, based on the simulation data of water quality obtained by using EPANET software,and applying entropy weight theory in the fuzzy evaluation of water quality, fuzzy evaluation model of water quality based on entropy weight and EPANET is established. Water quality in water distribution system of Hengshanqiao town is evaluated by using this method.Evaluation results are relatively objective and credible, proving that the method is simple and practical, scientific and reliable.
