Zusammenfassung:	PURPOSE:To provide a way to purify subterranean water or earth by decomposing and removing a volatile organic halogen compound contained in subterranean water or earth efficiently using a natural bacterium. CONSTITUTION:A volatile organic halogen compound is shifted to a gas phase in a diffusion tower 1 after gas-stepping the compound from subterranean water or earth. Then the gas containing the volatile organic halogen compound is allowed to come in contact with a natural bacterium capable of decomposing the gas in the presence of a derivative material at a processing tower 2. Consequently, this purification process is highly safe and does no longer cause a secondary contamination as the natural bacterium which can be easily obtained is used.
