The groundwater level still keeps increasing as it has been, according to Tepco.
On 12/5/2014, Tepco published the report of the groundwater levels in Reactor 2 seaside. The report shows the water levels rapidly increased from 11/25 to 11/27 due to the rainfall and are still in the continuous increasing trend until 12/4/2014.
The trend is observed at least in 4 borings to show the groundwater level is rising in the entire area.
Tepco announced the pumping well is under maintenance, which can be the cause. However the purpose is not explained. It is not announced when it is going to end either.
