Abstract: Chlorination has been the major strategy for disinfection of drinking water in Taiwan. The objective of this study is to classify and evaluate the factors of temporal-spatical explicitly for the influence of total trihalomethanes (TTHMs) concentration. The temperature for finished water increasing from northern to southern ranged from 20.4–27.1 °C. pH ranged from 6.7–8.3. TCM is the main content of THMs, the range was from 1.3–18.5 μ g/L, and the DCBM range was from 0.2–6.2 μ g/L. That conformed to the tendency of temperature of spatical factor in Taiwan. DBCM and TCM were predominant in Peng-Hu (11.2 and 24.8 μ g/L, respectively) because the water source was groundwater which near the coast and had higher bromide concentration.
