Xinhua: Very high radioactivity levels were detected in groundwater from an observation well at the crippled Fukushima Daiichi nuclear plant, said the plant operator Tokyo Electric Power Co. (TEPCO) Wednesday. [...] The observation well was set up on the Pacific side of the plant’s No. 2 reactor turbine building last December to find out the reasons why radioactivity levels in seawater near the plant remained high. The company said the sampled water could be from the contaminated water that seeped into the ground.

Reuters: Testing of groundwater showed the reading for strontium-90 increased from 8.6 becquerels to 1,000 becquerels per litre between Dec. 8, 2012 and May 24

BBC News: High levels of a toxic radioactive isotope have been found in groundwater at Japan’s Fukushima nuclear plant, its operator says. [...] Strontium-90 is formed as a by-product of nuclear fission. Tests showed that levels of strontium in groundwater at the Fukushima plant had increased 100-fold since the end of last year, Toshihiko Fukuda, a Tepco official, told media.

NHK: Tokyo Electric has again drawn criticism for a delay in revealing the latest incident. Workers took a sample of the groundwater on May 24th. [...] They apologized for the delay.

NHK: [Fukushima] prefecture summoned the utility’s managing director, Akio Komori, to the prefectural government office on Wednesday. Komori apologized for the trouble
