Bypass water discharge increased groundwater level in Fukushima plant

Contrary to expectation, bypass water project increased a part of the groundwater level, from Tepco’s report released on 9/25/2014.

On 9/16/2014, Tepco compared the groundwater level at 3 sub-drains beside the reactor buildings to the water level before bypass water project.

As a result, in 2 sub-drains the recent water levels didn’t show significant improvements from the regression line based on the data from 4/1/2012 to 5/20/2014, which Tepco concluded that “Water level decreased at least by 10 ~ 15cm due to bypass water project”.

In the 3 rd sub-drain, the recent water levels were above the regression line for some reason, which means the water level went higher than before. Regarding this data, Tepco stated “No decrease of groundwater level was observed” however Professor, Okamoto from Tokyo University, a member of contaminated water task force commented Tepco should clearly state the water level INCREASED due to the bypass project.

The exact cause is not identified yet, however Tepco simulated groundwater bypass would end up gathering water from the surrounding areas in 2013 by themselves.
