The leaked water was some of the most severely contaminated water following the 2011 tsunami. Of the leaked water, a liter contained [on average] 230 million becquerels of particles giving off beta radiation, as reported by Tepco. Among the 230 million particles, about half are believed to be strontium 90. Strontium 90 can be directly linked to bone cancer and leukemia if absorbed by the body. The water surpassed the safety levels by 3.8 million times the amount of strontium 90 allowed.
Despite criticism, the government has left Tepco the responsibility of cleanup following the 2011 tsunami. Critics claim that Tepco is too slow in recognizing and caring for any problems and they fail to alert the public as to the true conditions the plant is facing.
One problem Tepco has been constantly dealing with is the water that has been seeping into the damaged buildings. They must pump the water out of the plant and into special containers to prevent it from running into the Pacific Ocean. So far, they've contained over 340,000 tons of the contaminated water.
