TOKYO, Sept. 6 (UPI) -- Toxic water at the crippled Fukushima nuclear power plant may have mixed with groundwater near a leaky water storage tank, Tokyo Electric Power Co. said.
Tepco officials said detection of radioactive substances indicates the possibility that toxic water from the tank may have reached the groundwater, estimating that about 300 tons of highly toxic water had leaked from the tank, the Kyodo news agency reported Friday.
