Chlorine is widely used disinfectant and reacts with natural organic matter (NOM) in  waters to form disinfection by‐products (DBPs). Trihalomethanes (THMs) and haloacetic acids (HAAs) are the most common DBPs and potentially hazardous to environment and human health. In this study, water sample was obtained from Altinapa Dam, which has been used for the domestic and industrial water supply purposes in Konya. Dissolved organic matters in the dam water sample were isolated using a reverse osmosis membrane. The isolate was diluted with distilled water to adjust the different organic matter concentrations. Formation and speciation of four THM compounds were determined at different organic matter concentrations. The range of total THMs concentrations are 58‐108 μg/L and chloroform (CF) is 63‐89 % of total THMs. Increasing organic matter concentrations increase THMs concentrations
