TAMURA, Fukushima Prefecture--Bulk bags filled with greenery collected during decontamination efforts after the nuclear disaster at the Fukushima No. 1 nuclear power plant were swept into a river during Typhoon No. 19 on Oct. 12.
According to the Tamura city government, the bags were among 2,667 that have been stored temporarily at a site in the Miyakoji-machi district here.
The facility was flooded after heavy rains brought by the typhoon, and the water carried an unknown number of the bags to a river about 100 meters away.
A city government official received a phone call at around 9:20 p.m. on Oct. 12 from a nearby civil engineering firm, saying six of the bulk bags had been recovered from the river.
Each of the bulk bags was 1 cubic meter in size. No sheets had been placed over the bags as a precaution against the rain and wind from the typhoon.
A city official said consultations will be held with the Environment Ministry to determine possible effects on the environment.
The decontamination effort involved removing debris, such as soil, leaves and plants, containing radioactive substances released after the 2011 triple meltdown at the Fukushima No. 1 plant.
