On December 4, Tokyo Electric says they found a leak in a desalinization unit. It’s not a small leak, so far 45 tons of contaminated water has poured out.
What’s really interesting is that the de-salting unit is supposed to be treating water that had already had radioactive contaminants removed. TEPCo is saying the water is contaminated with 130,000 becquerels per cubic centimeter of strontium!
Company officials say it is highly likely that the strontium contaminated water made it into the Pacific Ocean, because there is a drainage ditch nearby leading to the ocean. It’s most likely strontium 90, which has a half life of 28.8 years, and causes many cancers including bone cancer.
TEPCo also made confusing statements; one said workers had checked the unit just 21 hours prior and found no signs of leaking, but then in another statement TEPCo officials admitted they did not act fast enough (a now typical trait of TEPCo management) as it was known that water was building up inside the unit, but they thought it would not leak out.
TEPCO says it will take them two weeks to improve their leak detection of the water treatment units.
