Tepco to “improve” the ground to stop groundwater contamination spreading by crushing an observation hole
Having measured extremely high level of Tritium from groundwater [URL], Tepco is going to improve the ground in order to stop contaminated groundwater flowing to the sea.
(cf, Tepco to build over 200 underground structures of water glass to 13 m deep underground to stop Tritium spreading [URL 2])
(cf, Former Fukushima worker, “Chemical injection doesn’t solve groundwater contamination problem” [URL 3])
They are going to inject chemical material to the ground from 7/8 to the end of July 2013.
However, the underground structure will be built exactly on one of the borings, which they detected 600,000,000 Bq/m3 of Tritium from. This boring is only 4 ~ 5m from the sea. The radiation readings from the samples of this boring are important to know the potential effect to the sea contamination. It is not known how efficient to stop spread contamination the ground improvement would be but we will lose one of the most suggestive observation holes for sure.
