TEPCO is expanding its storage capacity to about 1.9 billion gallons by clearing forest and other areas around the compound. While this would probably suffice for another three years, the site is running out of storage space. Additionally, some of the storage tanks have begun to leak and contaminated water is leaking into the soil.

To address these difficulties, TEPCO is proposing to treat its radioactive water to remove some of the radioactivity, and then release the rest into the Pacific Ocean. There is local opposition to this plan, especially from fishermen.
In July 2012, as some officials were assuring the public that fish from the Pacific were safe to eat, the Japan Fisheries Agency compiled statistics showing the opposite. As reported by a Canadian website, Vancouver's straight.com:
"The numbers show that far from dissipating with time, as government officials and scientists in Canada and elsewhere claimed they would, levels of radiation from Fukushima have stayed stubbornly high in fish.
"In June 2012, the average contaminated fish catch had 65 becquerels of cesium per kilo. That's much higher than the average of five Bq/kg found in the days after the accident back in March 2011, before cesium from Fukushima had spread widely through the region's food chain. In some species, radiation levels are actually higher this year than last."
What We Know is Dwarfed by What We Don't Know About Radioactivity
In March 2013, researchers from the Stanford University Hopkins Marine Station issued a report on Bluefin tuna caught off the California coast and tested for radioactive cesium. The report found that Bluefin tuna were 100 per cent contaminated, that not one was cesium-free. The report did not address such questions as whether cesium would continue to accumulate in tuna or whether it was appearing in other fish species.
