Abstract
Groundwater pollutions by chlorinated hydrocarbons have been frequently happened in Japan. In Fukuoka City, groundwater pollution by tetrachloroethylene (PCE) has been recently noted. PCE and various ions in this water were quantitatively analyzed, as well as the gas concentration of PCE in the soil and content of PCE at each depth of soil layer in attempt to find countermeasures. PCE in laundry water and soil was shown to be the source of pollution, and was assumed to permeate at locations of drying machines and sludge yards. High pollution by PCE was formed to be limited inside of narrow area surrounding the source.
