Fukushima workers were building the underground wall only a few meters away from the location that they measured 5,000,000,000 Bq/m3 of Strontium-90 from the groundwater of. However, Tepco didn’t inform the workers of the contamination level for over half a year.
The extremely contaminated water got on the boots of workers while they were injecting the chemical material underground. They had to pile macadams up to 1m high with the lead plate on the top to avoid the contamination, according to Tepco.

Background information on Fukushima
Arjun Makhijani, nuclear expert and President of the Institute for Energy and Environmental Research: Ground water is contacting the molten fuel and becoming extremely contaminated […] The fuel is molten and the bottom of the reactor building is undoubtedly damaged. So that’s why the ground water flowing past the trenches and pipes and past the basement of the reactor building is getting into the reactor building where the molten fuel is. It may also be that the molten fuel is in the cracks of the foundation.
Associated Press: The turbine buildings at the Fukushima Dai-ichi plant are about 150 meters (500 feet) from the ocean. According to a Japan Atomic Energy Agency document, the contaminated underground water is spreading toward the sea at a rate of about 4 meters (13 feet) a month. At that rate, “the water from that area is just about to reach the coast,” if it hasn’t already, said Atsunao Marui, an underground water expert […] on a government committee studying the contaminated water problem. “We must contain the problem as quickly as possible.”

A record high level of 710,000 becquerels of beta-ray sources, such as radioactive strontium, was detected per liter of water in an observation well at the crippled Fukushima No. 1 nuclear plant.
Tokyo Electric Power Co. said Nov. 12 the water was taken Nov. 10 at the well 10 meters north of a tank that leaked 300 tons of highly contaminated water before the problem was discovered in August.
The previous high reading of 550,000 becquerels per liter was found in water sampled Nov. 9 at the same well.

Hirose Takashi, journalist/former engineer: As we speak, radioactive material is seeping through Fukushima’s ground. It makes its way underground, reaches the ocean, to finally end up in the sky.
This kind of fact does not make the news, so everyone forgets about it. If that was talked about every day in the news, the Japanese population couldn’t ignore it. […] In my opinion mass media bear most of the responsibility for it. […] Incidents happen because mass media never take the problem seriously.
Georgia Straight (Canada), Oct. 2, 2013 (Emphasis Added): […] Two nuclear experts who saw the Straight’s figures said the real cancer toll could be 100 times higher—or 80,000 cancers. […] That could be the toll, [Daniel Hirsch, a nuclear-policy lecturer at the University of California at Santa Cruz, said in a phone interview], if all factors are taken into account, including: future fish consumption; highly damaging isotopes that were released in the disaster but aren’t being monitored, such as strontium 90 and plutonium 239; consumption of contaminated fish caught in the entire Pacific; and research suggesting that radiation causes many more cancers than official formulas predict. […] “Apologists say it’s a large ocean and dilution is the solution to pollution […] Dilution actually does nothing except expose a larger population.” […] The cancer numbers also don’t include other possible health impacts from radiation in the fish, such as heart disease, stillbirths, and genetic damage to subsequent generations.

– Japan finds highly toxic strontium in Fukushima groundwater (Reuters, June 19, 2013):
TOKYO (Reuters) – High levels of a toxic substance called strontium-90 have been found in groundwater at the devastated Fukushima nuclear power plant in Japan, the utility that runs the facility said on Wednesday.
Strontium-90 is a by-product of the fission of uranium and plutonium in nuclear reactors as well as nuclear weapons, the U.S. Environmental Protection Agency says on its website.
The discovery of rising levels of such radioactive material is likely to complicate efforts by the utility, Tokyo Electric Power Co, to get approval to release into the Pacific Ocean what it calls water contaminated with low levels of radiation.
“This contaminated water should not be released to the ocean,” said Michiaki Furukawa, a nuclear chemist and professor emeritus at Nagoya University. “They have to keep it somewhere so that it can’t escape outside the plant.”
Plutonium – the deadliest substance on the planet – has been injected into dogs and no dose was low enough to not give those dogs cancer, according to Dr. Helen Caldicott.
– Radioactive water problems at Fukushima nuke plant force rethink (Kyodo News, April 20, 2013):
TOKYO – The government and Tokyo Electric Power Co. will present broad new thinking in May on ways to prevent radioactive water from increasing at the crippled Fukushima Daiichi nuclear power plant, industry minister Toshimitsu Motegi said Friday.
Motegi made the remarks during a meeting to discuss the decommissioning process of the plant’s stricken reactors, as TEPCO continues to grapple with water leaks found recently at several underground storage tanks at the site.
The Nuclear Regulation Authority released an estimate the same day that the leaks could lead to the density of radioactive strontium in groundwater exceeding the legal limit in about 10 years in the coastal area of the plant.
