Water sampled from a well at the crippled Fukushima No. 1 nuclear plant has been found to contain levels of radioactive tritium that exceeds the limit for dumping it into the Pacific, operator Tokyo Electric Power Co. said.
The discovery was the first report of over the limit tritium in groundwater at the wells since Tepco began discharging water into the ocean last week.
In samples taken from one of the 12 wells on Monday, 1,700 becquerels per liter of tritium was detected, exceeding the maximum limit of 1,500 becquerels, the utility said on Tuesday.
Tritium levels in samples taken last month also topped the limit.
Tepco stopped pumping water from the well on Tuesday night, and said it plans to step up groundwater monitoring.
The utility is now releasing groundwater from the 12 wells into the sea after temporarily storing it in tanks and checking radiation levels.
