In 1979 the United States Environmental Protection Agency (USEPA) state that the maximum of the concentration for the tri halo methane is 1 μg/L of potable water. But the 80mg/L is the maximum level of the contaminant. There are several method that can measure the tri halo methane such as High Performance Liquid Chromatography (HPLC) and gas-chromatography with electron capture detection (ECD), static headspace system and dynamic headspace (purge and trap) with ECD, electrolytic conductivity and mass-spectrometry and gas chromatography flame ionization detector (FID). The most popular method that are used in Europe is purge and trap method. After identify the component in the water the different of temperature contact with THMs will give effect would be identify. Based on the several sample are taken such in Perak Tengah was measured such as institute area, houses area, refinery area and industries area. These source can shows the different level of THMs with different level of temperature and concentration. THMs formation is accelerate by high temperature of 60ᵒC and 90ᵒC. The THMs found in waste water from industrial site using spike chlorine sample at 5ppm dosage is 4.46 ppm at 90ᵒC.
