Abstract

Introduction: Chlorination is the most common and successful method for disinfection of drinking WATER, especially in developing countries. However, due to the probability of formation of disinfection by-products especially TRIHALOMETHANES (THMs) that are known as hazardous and usually CARCINOGENic compounds, this study was conducted to assess the investigation of THMs in drinking WATER of Abbas Abad WATER treatment plant in 2015.Methods: In this study, 81 WATER samples were gathered during autumn season of 2015. Temperature, pH, Ec, turbidity, and residual chlorine were measured on site. After samples preparation in the laboratory, THMs concentrations were determined using GAS CHROMATOGRAPHY. All statistical analyses were performed using the SPSS statistical package.Results: The results showed that the minimum and maximum mean concentrations (mg/l) for bromodichloromethane were 1.47 ± 0.57 and 1.90 ± 0.26, for bromoform were 1.47 ±0.35 and 2.36 ± 1.10, for dibromochloromethane were 1.47 ± 0.42 and 1.53 ± 0.55, and for chloroform were 3.40 ± 0.70 and 7.53 ± 1.00, and all compounds were determined for stations 1 and 3, respectively. Also comparing the mean concentrations of assessed THMs with ISIRI and World Health Organization (WHO) Maximum Permissible Limits (MPL) showed significant differences (P<0.05). Thus, the mean concentrations of all TRIHALOMETHANES compounds were significantly lower than the maximum permissible limits.Conclusion: Although the mean concentrations of THMs were lower than MPL, yet due to discharge of restaurants and gardens’ wastewater into the Abbas Abad River, prechlorination process of WATER in Abbas Abad WATER treatment plant, high retention time and increasing loss of foliage into the WATER, especially in autumn season, the formation of TRIHALOMETHANES compounds could increase. Therefore, periodic monitoring of THMs in drinking WATER distribution network is recommended.
