Having measured the significantly high level of Tritium from groundwater on the east side of reactor2, Tepco made additonal borings and is investigating furthermore. On 7/3/2013, Fukushima Diary reported they detected 4,300,000 Bq/m3 of all β at 6m from the sea. (cf, All β nuclide level increased to be 4,300,000 Bq/m3 at 6m from the sea, "1.4 times much as 3 days ago" [URL]) On 7/5/2013, they measured 900,000,000 Bq/m3 of all β from the groundwater. The sample was collected from another boring next to the one where they detected 4,300,000 Bq/m3. All β nuclides contain Strontium-90 but the specific readins is not announced. This is the worst reading of groundwater contamination that Tepco has ever published. http://www.tepco.co.jp/cc/press/2013/1228749_5117.html

Radiation of 750 million becquerels a liter of cesium-134 and 1.6 billion becquerels a liter of cesium-137 was recorded, Tepco said. The normal limits for the two potentially harmful isotopes are 60 and 90 becquerels, respectively. In April 2011 a combined 1.8 billion becquerels was recorded.

Monitoring for Radiation in Seafood (Res. 414):The delegates adopted an amended California resolution that asks AMA to call for the federal government to continue to monitor and fully report the radioactivity levels of edible Pacific Ocean species sold in the United States that could reasonably have been exposed to radiation from the ongoing Fukushima disaster and to include the potential health implications of consuming such foods.

On 7/27/2013, Tepco announced they measured 2,350,000,000,000 Bq/m3 from retained water of seaside trench of reactor2.
