To confirm the possibility of sure and efficient decomposition of pollutant in a polluted region by microorganisms present in situ through a decomposition experiment of the pollutant in situ.
The confirmation method includes processes of: pumping up groundwater in the polluted region 1 by a liquid metering pump 3 through a pumping hose 2; activating and growing anaerobic microorganisms present in the groundwater by passing the groundwater through a microorganisms growth space 4 packed with a microorganism activating agent; returning the underground water containing grown anaerobic microorganisms to the vicinity of a pumping point through a return hose 5; and measuring the concentration of the pollutant by sampling part of the groundwater before returning with a sampling bottle 6. Lowering state of the measured concentration after lapse of a predetermined time allows the confirmation of the applicability of the microorganism purification method.
