On 24 February 2015, the Tokyo Electric Power Company (TEPCO) issued a press release saying that the source of high radiation levels in one of its drains came from a puddle of rainwater that had accumulated on the rooftop of Unit 2 at the Fukushima Daiichi Nuclear Power Station. The drain leads to open seawater. It was thus suspected that contaminated water may have leaked into the sea, although TEPCO found ‘no increase in radioactivity’ in the seawater in the area.
