Objectives To investigate the pollutant levels of regulated disinfection by-products trihalomethanes (THMs) and haloacetic acids (HAAs) in raw water from the Huangpu River,the Yangtze River and different treatment processes and finished water, and to explore the changes tendency in transmission and distribution pipeline network. Methods A total of 65 ml water samples with two replicates were collected from different raw water, corresponding treatment processes, finished water and six national surveillance points in main network of transmission and distribution,water source for A water plant and B, C water plant was the Huangpu River and the Yangtze River, respectively. Regulated THMs and HAAs above water samples were detected by gas chromatography. Results The total trihalomethanes (THM4)concentration in different treatment processes of A water plant was ND - 9.64 μg/L, dichlorobromomethane was the highest (6.43 μg/L). The THM4 concentration in B and C water plant was ND to 38.06 μg/L,dibromochloromethane ( 12.24 μg/L) and bromoform ( 14.07 μg/L) were the highest in the B and the C water plant respectively. In addition to trichloroacetic acid in A water plant from the raw water, the other HAAs came from different treatment processes. The total haloacetic acids ( HAA6 ) concentration of different treated processes in A water plant was 3.21 - 22.97 μg/L, mobromoacetic acid ( 10.40 μg/L) was the highest. Dibromoacetic acid was the highest both in B (8.25 μg/L) and C (8.84 μg/L) water plant,HAA6 concentration was ND to 27.18 μg/L. The highest and the lowest concentration of THM4 were found from the main distribution network of C and A water plant respectively, but the concentration of HAA6 in the main water pipes network of A water plant was the highest, and the lowest in C water plant The THMs concentration was 21.11 - 31.18 μg/L in C water plant and 6.72 - 8.51 μg/L in A water plant. The concentration of HAA6 was 25.02 -37.31 μg/L in A water plant and 18.69 -23.32 μg/L in C water plant. The highest concentrations of brominated disinfection by-products in B and C water plant were 54.57 μg/L and 45.38 μg/L respectively,those were higher than A water plant ( 18.98 μg/L) ,and higher than the chlorinated disinfection by-products in B and C water plants (30.23 μg/L and 30.60 μg/L).Conclusions The THM4 concentrations of finished water treated from Huangpu River was lower than finished water from the Yangtze River, while the HAAs concentrations in finish water from Huangpu River was higher than the two water plants of Yangtze River. The fluctuations of THMs and HAAs concentration in distribution network were low during transmission and distribution process.
