Water may have leaked at Fukushima due to gauge errors

Contaminated water might have leaked from the damaged Fukushima nuclear reactors after erroneous settings on water gauges lowered groundwater levels nearby, the plant operator said Friday. Tokyo Electric Power Co. said the settings on six of the dozens of wells around the reactors were 70 centimeters (3 feet) below the requirement. Groundwater at one well briefly sank below the contaminated water inside in May, possibly causing radioactive water to leak into the soil. Groundwater samples have shown no abnormal increase in radioactivity and leaks to the outside are unlikely, TEPCO spokesman Shinichi Nakakuki said. Groundwater levels at wells dug closer to the reactors have stayed above minimum safety levels, suggesting that risks of a leak are unlikely, he said. The problem in the six wells launched in April was caught this week during preparation at another well nearby. The company said it is investigating.
